The system also includes a filtration unit between the sampler and privatbrauerei station. The filtration unit consists of a sealed overflow capacity with located in it the element of the controlled diaphragm foot valve, overflow fitting, diaphragm discharge valve and the capacity of accumulation of filtrate for subsequent regeneration of the filter element. The filter element is sealed to the storage capacity of the volume of the filtrate for subsequent regeneration of the filter element. To the bottom of the overflow tank attached driven diaphragm bottom valve. The upper part is made with overflow and drain connected to a diaphragm relief valve.

The disadvantage of this device is that the filtering is done outside of the working environment, resulting in changes of physical parameters (temperature, pressure) at which the separation of the solid phase from the solution, which in turn changes the composition of the filtrate.

The technical result is to improve the accuracy of obtaining representative samples of the chemical composition of environments occurring in conditions of high temperatures and pressures that will improve the accuracy of control of the chemical composition of the solution, in particular the technological parameters of the hydrometallurgical autoclave systems.

the Technical result is achieved by filter element is located in a working environment which is hermetically connected with the storage capacity of the volume of the filter attached to the line of withdrawal of the sample, and for the regeneration of the filter surface introduced hydraulic pulsator pressure which is set on the line of withdrawal of the sample between the ball valve and washer resistance, which also provides the sample into the sample receptacle in a sealed vessel having vodoohlazhdaemogo shirt button, located at the end of the line for discharging the filtrate, is equipped in its lower part a controllable two-way valve, fitting for supplying water used for the delivery lines of the sample.

The essence of the technical solution is illustrated by drawings. A device for filtering and sampling consists of a filter element 1 made of porous Ti, resistant to chemical attack from aggressive working environment. The filter is made in the form of a cylinder installed on the 2 for discharging the filtrate. In line 2 mounted ball valve 10, then a hydraulic pulsator pressure 4, which creates excessive hydraulic pressure in line 2 for cleaning the filter surface. Washer resistance 5 changes the ratio of the quantities allocated for the washing of the filter element and into the sample receptacle. This function can be performed by using a spherical cluster�Ana 11. The receptacle 6 and line 2 are made of chemically resistant materials Ti or from various alloy steels. For the operation of the receptacle used the ball valve 12 to reset abhasa and two-way diaphragm valve 9 is to drain the filtrate. The receptacle 6 is provided with a water-cooled 7. Filter control is carried out by differential pressure gauges installed in the production environment, the pressure gauge 14 and the line of drainage of the filtrate - pressure gauge 15. Flushing of the system is performed by applying water 3 in a line through the ball valve 13. System management and transmission of information produced by the controller 8, the control solenoid ball valves 10-13 and three-way membrane valve in accordance with the sequence diagram.

Filter element made of porous titanium metal, resistant to aggressive influences of environments, which is hermetically connected with the storage capacity of the volume of the filtrate. When sampling the filtered fluid passes through the filter element due to the pressure created by the working environment. To ensure uniform sampling of leachate from slurries with a high content of solid particles in the sampling line used hydraulic pulsator pressure (GPA). Part of the filtered liquid goes on cleaning the filter element, and the part enters in probable�nick. Thus, each time the excessive pressure of the AAPS in line 2 is cleaning of the filter element, which makes the flow of the filtrate stable.

For sending larger quantities on the filter element and not in the receptacle, in-line sampling set washer resistance. Additionally to regulate the flow of solution is used as the throttle valve ball located between the washer resistance and receptacle.

The pressure gauge on the line of withdrawal of the sample, performs the function of monitoring the filter. The difference between the pressure of the working medium and the pressure in the line to judge the condition of the filter.

The receptacle is made in the form of sealed containers, equipped with water-cooled jacket for cooling the filtrate. To drain the solution in the bottom of the sampler using a controlled ball valve and dochodowy diaphragm valve. Valve located above the receptacle, correct abhasa, lower to drain the solution. For washing line delivery samples use fitting, feeding wash water into it.

Line for discharging the filtrate is made of resistant alloy due to the effects of corrosive fluids, high temperatures and pressures.

The control unit, readout and data transfer is provided with a programmable logic�skim the controller and the program for the control sample. A device for filtering and sampling of liquids in pressure vessels can operate both in automatic and in manual mode.

A device for filtering and sampling of liquids in pressure vessels operates as follows. Initially, all valves are closed. At a signal from the controller 8 is the opening of the ball valve 10, line 2 of the drainage of the filtrate is filled with a solution. When the minimum differential pressure gauges 14 and 15 switches the hydraulic pulsator pressure 4. Open the ball valve 11, the filtrate enters the receptacle. When the pressure difference on the pressure gauges 14 and 15 are zero, which controls the filling of the sampler closes the valve 11. After a while the filtrate is cooled by a water-cooled 7 to an acceptable temperature, then drain the filtrate by sequential opening of the ball valve 12 and the two-way diaphragm valve 9 for draining the vessel for the filtrate 16. Then rinsed the water supply system 3 in a line through the ball valve 13 and switching the three-way diaphragm valve to drain into the tank for the washing solution 17. If necessary, the filling cycle of the sampler again. At the end of the selection disconnects the hydraulic pulsator pressure, closes the ball to�of apan 10 and sequentially open the valves 11, 9 and 12 for relief of pressure in line 2.
