Abstract
The utility model discloses a recovery VCM filter, which comprises a sealed barrel, wherein the upper end and the lower end of the barrel are respectively provided with an upper closure head and a lower closure head, the barrel is provided with a feed inlet, a screen plate is arranged in the barrel, a plurality of filter elements are vertically arranged on the screen plate, the barrel is communicated with the lower closure head through the filter elements, and an absorbent cotton layer is coated outside the filter elements. When in work, recovery gas is shunted through an air current distributing plate arranged on a feed inlet position after recovery gas enters through the feed inlet, recovery gas is evenly distributed on each filter element best, and the recovery VCM filter prevents gas with higher flow velocity from damaging the filter elements on an inlet, and leads each filter element to play a filter function, gas flows out from the middle portion of the filter elements after filtering by the filter elements, and enters the lower closure head, clean gas flows out through a discharge hole, and enters a next procedure. Filter precision is led to reach 1000 micron through filtering by a plurality of filter elements, and impurities in feed liquid can be effectively filtered.
Description
Technical field
The utility model relates to a kind of filter that the tetrabromobisphenol A production process is reacted the back feed liquid that finishes that is used for, and relates to a kind of recovery VCM filter specifically.
Background technology
Reclaim after the polymerization in process of production because big in the blowpit with recovery system pressure reduction, the gas phase flow velocity is fast during recovery, the top gas-phase space can produce a large amount of foams and entrained particles when the blow tank liquid level is high, will and reclaim compressor to the recovery condenser of postorder and result in blockage even damage as not carrying out filtration treatment, because the PVC particle that foam is carried secretly generally all is superfine, the particle that unreacted is intact, general net type filter can not filter it fully, the filter that uses must can reach this filtering accuracy, it could be filtered fully.
The utility model content
The technical problems to be solved in the utility model is a kind of recovery VCM filter that good filtration effect is provided at the deficiency of technique scheme.
For solving the problems of the technologies described above the technical solution of the utility model be:
A kind of recovery VCM filter, the cylindrical shell that comprises sealing, the two ends up and down of described cylindrical shell are respectively equipped with upper cover and low head, described cylindrical shell is provided with charging aperture, be provided with filter in the described cylindrical shell, some filter cores vertically are set on the described filter, and cylindrical shell is communicated with low head by filter core, and described filter core coats degreasing cotton layer outward.
Below be to further improvement in the technical proposal:
The position of charging aperture is provided with the airflow-distribution board that is used for shunting gas in the described cylindrical shell.
The lowermost end of described low head is provided with sewage draining exit, and the position near low head on the cylindrical shell is provided with discharging opening.
Use technique scheme, during work, after recovery gas enters by charging aperture, shunt by the airflow-distribution board that is arranged on the charging aperture position, the recovery air-flow is evenly distributed on the every filter core as far as possible, prevent that higher gas flow rate from causing damage to the filter core of porch, every filter core can both be played a role in filtering, and gas is behind filter element filtering, by flowing out in the middle of the filter core, enter low head, clean gas flows out by discharging opening, and next step operation that enters uses the utility model to filter by a plurality of filter cores, make filtering accuracy reach 1000 microns, can filter the impurity in the feed liquid effectively.
The utility model is described in further detail below in conjunction with the specific embodiment of accompanying drawing:
Description of drawings
Accompanying drawing 1 is to reclaim VCM structure of filter schematic diagram among the utility model embodiment;
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to cutaway view.
Among the figure: the 1-cylindrical shell; The 2-filter core; The 3-charging aperture; The 4-discharging opening; The 5-evacuation port; The 6-sewage draining exit; The 7-bracing frame, 8-upper cover, 9-filter, 10-low head, 11-degreasing cotton layer, 12-airflow-distribution board.
The specific embodiment,
Embodiment, as accompanying drawing 1, shown in 2, a kind of recovery VCM filter, the cylindrical shell 1 that comprises sealing, the two ends up and down of described cylindrical shell 1 are respectively equipped with upper cover 8 and low head 10, described cylindrical shell 1 is provided with charging aperture 3, be provided with filter 9 in the described cylindrical shell 1, on the described filter 9 some filter cores 2 are set vertically, cylindrical shell 1 is communicated with low head 10 by filter core 2, the described filter core 2 outer degreasing cotton layers 11 that coat, have many small pores on the filter core 2, degreasing cotton layer 11 forms the twice filter course with filter core 2, and gas is filtered, and the position of charging aperture 3 is provided with the airflow-distribution board 12 that is used for shunting gas in the cylindrical shell, the lowermost end of described low head 10 is provided with sewage draining exit 6, cylindrical shell 1 is provided with support 7, and the position near low head 10 on the cylindrical shell 2 is provided with discharging opening 4, and upper cover 8 is provided with evacuation port 5.
During work, after recovery gas enters by charging aperture 3, shunt, the recovery air-flow is evenly distributed on the every filter core 2 as far as possible by the airflow-distribution board 12 that is arranged on charging aperture 3 positions, gas is after filter core 2 filters, by flowing out in the middle of the filter core, enter filter bottom, clean gas flows out by discharging opening 4, next step operation that enters, use the utility model to filter, make filtering accuracy reach 1000 microns, can filter the impurity in the feed liquid effectively by a plurality of filter cores.
