Invention relates to water engineering, particularly, to water treatment systems. Tricking filter comprises casing, waste water feed system, sprayer and bed. Said casing is composed of rectangular unit with dual bottom. upper bottom composed by fire grate and lower solid bottom with reinforced concrete walls and cover. Besides it comprises waste water dispensing tanks, waste being fed thereto via waste water feed system intake branch pipe. Note here that the height of bottom-to-bottom space should be at least 0.6 m. Trickling filter drainage should be made up of reinforced concrete plates to be laid on concrete supports. Note also that total area of opening for water flows into drainage system should make at least 5÷8% of trickling filter surface area. Water velocity therein should make at least 0.6 m/s. Note that waste water feed system comprises branched system of pipelines with sprayers equally spaced apart above filter bed. Note that lower bottom inclination to collection chutes makes at least 0.01 while lengthwise inclination of said chutes equals 0.005. Filter walls are made of prefabricated reinforced concrete and tower above bed surface for 0.5 m to decrease wind influence on water distribution over filter surface. Filter bed represents crushed stone and gravel. |

In the foam generator of vortex type the sprayer is connected to the housing of an ejecting nozzle made in the form of a diffuser mounted axially relative to the sprayer axis. On the housing of the ejecting nozzle in a part located closer to the sprayer at least three windows for ejecting air are made. Inside the ejecting nozzle by at least three spokes rigidly connected to the housing of the ejecting nozzle a dissector of two-phase flow in the form of a truncated cone, made of grid or perforated material is fixed. The smaller base of the cone is directed towards the sprayer, and the larger - towards the cut of the diffuser. The housing of the sprayer consists of two coaxial interconnected cylindrical sleeves. One of the sleeves has a larger diameter and the other - the smaller diameter. Inside the sleeve of smaller diameter, coaxially to it a screw is located, which is pressed into it. The outer surface of the screw represents a helical groove. Inside the screw an opening with a screw thread is made. In the sleeve of greater diameter, coaxially to it, a fitting is located, rigidly mounted in it by a threaded connection through the sealing gasket. Inside the fitting a cylindrical opening is coaxially passing into axially located diffuser, which is connected to the cylindrical chamber. The cylindrical chamber is formed by the inner surface of the sleeve of smaller diameter and the end surface of the screw. |

Vortex straying drier for disperse materials Proposed drier comprises cylindrical drying chamber with nozzles arranged in chord to feed heat carrier, axes of said nozzles being located tangentially to imaginary circle. Besides it incorporates sprayer located in chamber axis. Note here that said drying chamber is composed by two different-diameter cylinders, smaller of which features diameter making 1.0-1.5 of said imaginary circle diameter. Note also that nozzles are located at the distance from smaller cylinder cross-section not exceeding two diameters of the nozzle. Blades are arranged in drying chamber, level with nozzles in planes parallel with chamber axis, at h=aR therefrom and inclined opposite nozzle gas flow, where a is location of nozzles in chord and R is chamber diameter. Said blades can displace in chamber axis and turn in the plane perpendicular to said axis. At least two slotted nozzles are arranged at larger cylinder inner wall. Note that nozzles are arranged in manifolds communicated via pipelines with manifold for feed hot gases and directed tangentially to larger cylinder diameter at contact points between manifold and larger cylinder inner wall. Atomiser comprises cylindrical hollow case with fluid feed channel and coaxial sleeve rigidly coupled with said case and having nozzle secured at its bottom. Said nozzle is composed of cylindrical two-step sleeve. Top cylindrical step of the latter is screwed to central core composed of cylindrical part and hollow cone aligned therewith. The latter is fitted with clearance relative to cylindrical sleeve inner surface. Said circular clearance is communicated with, at least, three radial channels made in said two-step sleeve to communicate with circular cavity formed by sleeve inner surface and top cylindrical step outer surface. Note that circular clearance is communicated with case fluid feed channel. Sprayer is screwed to cone bottom. Said sprayer is composed by round end plate with edges bent towards said circular clearance. Note here that at least two rows of cylindrical orifices are made in the cone side surface in planes perpendicular to cone axis. Each row has, at least, three holes. Axes of aforesaid throttling holes of one line are displaced relative to those of the other lines through the angle varying from 15° to 60°. Helical grooves are made on cylindrical orifice inner surface, at cone side surface, and features axes located in the pane perpendicular to case axis. |

Device for hermetic storage of fluid substances and their delivery Invention refers to device for hermetically stored fluid substances delivery by means of manually controlled pump and may be used for storage and delivery of cosmetic or medical substances. Device for fluid substances hermetic storage and their delivery contains a rigid container with a threaded neck restricting an opening. The neck opening provides access to the container cavity. The device is also provided with a bag from thermoplastic material enclosed in container with its own neck, a flange passes radially from the container. The flange restricts an opening in order to provide access to the bag cavity and to enclose a housing of manually controlled pump for removal of fluid substance from the bag and its delivery outside through the pump delivery rod. Pump housing is pressed to form a packing on the bag flange by the first annular cap. The device contains the second annular cap screwed on container neck and attached to the bag. The first annular cap is attached to the second annular cap. Engagement means are provided between the first and the second annular caps in order to make the first and the second cap torsionally rigid with each other. Rotation applied to the first annular cap of the pump results in corresponding rotation of the second annular cap thus facilitating an empty bag removal from container caused by pump removal from the container. Provided is at least one channel for air penetration outside the container in a gap between inner surface of the container and outer surface of the bag enclosed in it. The second annular cap is attached to the bag by a flange located between the second annular cap and the first annular cap. |
