The invention is illustrated in the drawing, which schematically presents the production line cleaning paste for cleaning a solid surface on the basis of mineral sludge from a waste product of protein-vitamin concentrate and slag dry gas purification smelter JSC "Volgograd steel works "Red October".

Information confirming the possibility of implementing the claimed invention are as follows.

H is stasha paste for cleaning a solid surface contains the following known components: sulfonic acid (alkylbenzenesulfonate sodium), soda ash, perfume, mineral sludge from a waste product of protein and vitamin production and brine natural mineral bischofite.

Mineral sludge from a waste product of protein and vitamin production contains mainly nevadacalifornia the rest of the map. Physico-chemical characteristics of mineral sludge are presented in table 1. To improve disinfection ability of pasta in its composition brine natural mineral bischofite (bishofit) formula MgCl₂·6N₂About density of 1.2-1.3 t/m³. Natural deposits of mineral bischofite according to geological exploration only in the Volgograd region are estimated at billions of tons. The composition of the samples of bischofite brine, extracted in the fields of the Volgograd region in salt form, are shown in table 2. Chemical analysis of the samples and the content of macro - and micronutrients are presented in table 3. Analysis of samples bischofite brine from different fields are shown in table 4. The composition of bischofite brine, extracted within regional, is given in table 5.

Declared pasta is made in the following ratio, wt.%:

The sulfonic acid is introduced into the composition of the paste as a bactericide. He refers to the anionic surface-active substances, to the group of alkylarylsulfonates. It is the product of alkylation of benzene fraction of olefins in the presence of aluminum chloride catalyst composed of a mixture of sodium salts of alkylbenzenesulfonic with alkyl residues predominantly normal structure containing 11-12 carbon atoms.

By the looks of the sulfonic acid - liquid paste yellowish-brown color. The content of sodium salts alkylbenzenesulfonic - 50-55%; sodium sulfate is about 6%; desulfuromonas compounds is about 1%. The sulfonic acid is highly soluble in water and alcohol.

The sulfonic acid in p is edlagaemoe recipe at the same time plays the role of a disinfectant component and the role of surfactants, informing the song good wetting and washing ability. In addition, the composition with him has a good pastos without the introduction of the formula water.

As the primary cleaning agent used recycled mineral sludge from waste production of microbial protein from carbohydrates oil obtained at the stage of preparation of a solution of nutrient salts. The formation of mineral slurry of protein-vitamin concentrate (paprika), for example Svetly Yar plant for the production of protein-vitamin concentrate in the Volgograd region is annually 5000 so currently in the dumps accumulated more than 70,000 tons of sludge waste. Physico-chemical and thermal characteristics of mineral sludge from the waste production of protein-vitamin concentrate (paprika) and scouring pastes based on it are shown in table 6. The content of the identified chemical elements in dry sludge waste production of protein-vitamin concentrate is given in table 7. Recycled waste in this composition not only provide a cleaning effect, but also partially remove unpleasant food odors that remain on the dishes. To enhance the deodorizing effect of the used brine natural mineral bischofite, which simultaneously ensures the sanitation of dishes.

Entered into a paste flavoring gives it matched the existing flavor.

Technical measures pastes are shown in table 8.

As agents that enhance the cleaning ability of the surfactant due to dispersing and emulsifying action, the recipe is entered sodium carbonate (soda ash). Soda ash technical, as a component of the paste must meet the requirements of GOST 5100-85.

Waste production of protein-vitamin concentrate, not used and going to the dump, in this part of the cleaning paste is used in its natural form and do not require additional deep processing. The introduction of the scouring pastes other abrasives is not required. In these waste contains finely dispersed calcium oxide (15%), phosphorus (up 13%), potassium (to 4.5%), iron (up to 4.4%) and nitrogen (up to 13.5%) (see table 7) with a particle size of 20-30 μm, which are a good abrasive. They are stretchy and contributes to the mechanical cleaning of contaminated surfaces. In addition, the phosphates are good detergent component. The content of other salts in the waste is low, and therefore completely harmless to humans.

The paste contains as filler slag dry gazoochistnoe smelting fraction of 5-100 μm from 12 to 18 wt.%. The chemical composition of the solid sludge from dust dry gas cleaning plant electric plant -1 CJSC "Volgograd metallurgical plant the Red October" are shown in table 9. Prepared after magnetocapacitive fractional composition of the slag dry gas purification is filler paste for removing rust and stubborn dirt in the micropores on the surface.

Example. Prepare three recipes pasta (1, 2, 3 - see table 10) based on the waste production of protein-vitamin concentrate and slag from the dust of dry gas purification. For this waste and slag add sulfonic acid, soda ash, odorant, brine natural mineral bischofite and water in amounts shown in table 10, and carefully, for 30 minutes, stirred to obtain a homogeneous mass. Prepared formulations suffer in comparison with the known pastes "Sanita" and "Supercall". The test results of physical and mechanical properties are given in table 11.

The data in table 11 show that the developed pasta has advantages over known as cleans the surface from rust. In addition, the paste has a number of other properties, in particular disinfectant, and protects the surface from corrosion.

Due to the MgCl₂in bischofite brine pasta is active against bacteria causative agents of intestinal infections, tuberculosis, upper respiratory infections (diphtheria, scarlet fever and other), fungi of the genus Candida, dermatophytes and viruses (pathogens influenza, and other acute respirato the different viral infections, viral hepatitis, HIV, herpes, rotavirus gastroenteritis).

Production line cleaning paste for cleaning a solid surface on the basis of slag from the dust of the dry gas cleaning system of steel production, mineral sludge from waste products of protein-vitamin concentrate and brine natural mineral bischofite includes a container 1 for dry and preparirovania sludge in the form of powder from waste production of protein-vitamin concentrate, capacity for 2 sulfonic acid, capacity 3 for soda ash, capacity for 4 odorants, means of transportation 5 interchangeable buckets 6, a mixer 7, the vibrator 8 for issuing a finished product from the mixer 7, the reserve tank 9 for the finished paste, working capacity for 10 ready paste, screw feeder 11, means 12 for filling and packaging of finished products, the conveyor 13 issue scouring pastes in the package in the interim storage. Backup and working tanks 9 and 10 are mutually connected by pipelines and pumps for pumping paste from one container to another or screw feeder 11.

The line is equipped with a capacity of 14 for brine natural mineral Sofit and capacity 15 for water. Containers 14 and 15 are connected hydraulically through the valves 16 and 17 with a mixer 7.

Standard sludge from the tank 23 in dosed quantities, according to the recipe in table 10, enters the tank 1.

Supplied slag from the dust of the dry gas cleaning plant electric plant -1 CJSC "Volgograd steel works "Red October" from the wagons unloaded in a closed processing space. Slag means of transportation 5 interchangeable buckets 6 (see process diagram) serves in an electromagnetic separator 29, and then the conveyors in the classifier 30 for separating slag fractions with fraction sizes 5-100 μm from the larger mass. The metal fraction and the coarse grinding back to the metallurgical plant as charge. Slag with fractional composition of 5-100 μm is sent to the mixer 7 together with other components.

Production line cleaning paste for cleaning hard surfaces is as follows.

Sludge ammophos waste production of protein-vitamin concentrate is supplied for the production of h is stasha paste with a moisture content (depending on time of year) 45-58% and stored on-site, protected from rain, for natural drying. The moisture content of sludge raw after natural drying should be no more than 45%. To obtain a paste bead size in the slurry should not exceed 0.2 mm, It will provide a high cleaning ability and will prevent abrasive damage to surfaces.

Sludge waste after natural drying using removable buckets 6 and means of transportation 5 (electric crane on the track) in the amount of 181,4 kg load into a hopper 18. Described line designed for 300 tons per year scouring pastes. Hourly capacity - 150 kg From the hopper 18, the portion of the slurry raw goes into the dryer 19. The carrier for drying is hot air, which is supplied from a heater in the dryer 19 in such quantity that the temperature of the drying unit in the zone of compaction of the sludge was not below +75°C. the drying portion of the sludge lasts no more than 1 hour. As the drying of the sludge (residual moisture not more than 5%), it enters into the intermediate hopper 20 and is cooled to ambient temperature.

Then in dosed quantities by a slide valve dry sludge is sent to the grinder 21. After fracture of the sludge mass is sent to the classifier 22. With the classifier 22 conforming fraction of sludge with a grain size less than 0.2 mm) is fed into the variable capacity 23 for condition the first slurry. Nonconforming fraction of the sludge from the portable tank 24 is re-directed into the intermediate hopper 20 for re-grinding. Dry conditioned slurry with the required mass is moved into the container 1.

When drying sludge raw together with the exhaust fluid is flue dust fraction of the sludge. Therefore, in the line at the exit of the coolant from the dryer 19 is provided by the cyclone 25, bag filter 27 and the fan 26. Due to the suction channel by the fan 26 is collecting dust fraction from the classifier 22. Settled dust from the cyclone 25 through the sliding gate 28 return into the intermediate hopper 20.
