Description

one

The invention relates to apparatuses of chemical technology and can be used in vapor condensers by its own cooled condensate in the chemical, petrochemical, and other industries.

The purpose of the invention is to increase the efficiency of the installation by reducing the stops for cleaning.

FIG. 1 shows a schematic representation of the proposed installation, the general view; in fig. 2 - section AA 1 in FIG. 3 - device for cleaning the sprayer hole of the installation.

The installation contains a condenser 1, with a sprayer 2 having a jet spin box with a central opening 3, as well as a cooled condensate collector 4. The latter is connected by a bar of an eteric pipe 5 to a condenser 1. A collector 4 is equipped with a submersible pump 6 connected by a pipe 7 to a spray gun 2. Inside the collector 4 there is an overflow threshold 8 located between the pipe 5 and the pump 6, made in the form of a vertical partition with a bent in direction to the pump 6, the upper edge 9, under which the filtering element 10 is installed, which is located adjacent to the cleaning port 11. The atomizer 2 is equipped with a device for cleaning the opening 3.

Inside the filter element 10 is installed auger 12 (Fig. 2).

The device for cleaning the chamber with a hole 3 (Fig. 3) of the spray gun 2 is made in the form of a cleaning rod 13 with a counter-drift mechanism and two cups 14. The last connections

They are located one to another with edges, are made with holes in the bottom pins and are installed in the lower part of the dispenser 2 coaxially with its central hole 3. In the first place of the jaws 14 on their edges there are holes 15 forming the tangential channels 16, which connect the cavity 17 formed by the cups 14 , with an internal volume of the sprayer 2. In the hole of the upper pulley 14 a cleaning rod 13 is installed, connected to the countercurrent mechanism. Upper pulley 14 has a reciprocating drive in the form of a rod 18 connected with a counter-flow mechanism.

This mechanism is made in the form of a rhomboid frame with links 19, hinged to each other. One of the hinges 20 is connected to the rod 18, the opposite hinge 21 is connected to the rod 13. Another pair of frame hinges 22 is installed perpendicular to the rod 18. The latter can be equipped with a piston 23 separating the cavity of the inner volume of the atomizer from the cavity 24 formed by the cap 25. In cavity 24 on handle 18, a handle 26 is installed, a spring 27 is compressed between the latter and the cap 25. The piston 23 and spring 27 together constitute the reciprocating mechanism of the counter-flow.

The installation works as follows.

Collection 4 is filled with refrigerant. Pump 6 delivers refrigerant to sprayer 2 through line 7. Refrigerant is sprayed in condenser 1 and condenses on its surface

steam removed, for example, from the apparatus of the de-monomeriser of the polymerization line (not shown). The mixture of refrigerant and condensate through barometric tube 5 is poured into collector A, from where overflow threshold 8 along edge 9 is poured into filtering element 10. Hardened particles, which can be formed during condensation of vapors of low molecular weight compounds, are precipitated together with extraneous solid inclusions in the coolant on the surface of the filter element 10 and removed from the collector 4 through the pipe 11 by the screw 12, C helps the heat exchange jacket condensate in the collector 4 is cooled.

As the refrigerant is filled with condensate, which is determined by the liquid level or sample analysis, part of the refrigerant / condensate mixture is pumped from pump 6 from collector 4 and used for technological purposes in the polymerization line, and fresh refrigerant is added to collector 4.

Spray 2 works as follows.

When channels 16 or a chamber with an opening 3 are blocked by particles formed in pipe 7, the pressure in the volume of atomizer 2 rises, so that piston 23 moves into cavity 24. At that, rod 18 raises cup 14, as a result of which particles blocked in channels 16 are released. At the same time, by transferring the counter-flow, the rod 13 is pushed into the hole 3 and cleans it. The flow of fluid through the spray gun 2 is resumed, the pressure in the pipe 7 and the volume of the gate 2 decreases, the rod 18 is closed by the cups 14 due to the action of the spring 27, and the normal operation of the spray gun 2 is restored. Solid particles are carried away with the mixture of condensate and coolant to collector A, where the filter element 10 is caught. The reciprocating movement of the rod 18 can be done manually with the help of the handle 26, for which the cap 25 from the top of the atomizer 2 is previously removed.

The organization of a free-flowing fluid flow in collection A for

by overflowing the threshold 8 with a bent edge 9 protruding toward the pump 6, installing the filter element 10 under it allows trapping solid particles in the liquid and cleaning the filter element 10 without stopping the installation. The installation in the filter element 10 of the screw 12 makes it possible to remove the filtered sediments without depressurizing the collector A, the refining of the sprayer 2 according to the proposed scheme allows cleaning the channels of the sprayer 2 without disassembling it, as a result of which the productivity of the installation increases.
