[0002] In the chemical production process, demister is an important equipment, widely used in various reactions and separation processes, to remove foam or impurities in liquid or gas. The gas passes through the wire pad of the demister to remove the entrained mist. The wire mesh demister is mainly composed of a wire mesh, a wire mesh grid to form a wire mesh block and a support device to fix the wire mesh block. The wire mesh is a gas-liquid filter mesh made of various materials, and the gas-liquid filter mesh is composed of metal wire or non-metal wire. The wire mesh demister can not only filter out larger liquid foam suspended in the airflow, but also filter out smaller and tiny liquid foam, and its defoaming effect is good.

[0033] The beneficial effects to be expressed by this scheme are as follows: by setting a sealed inspection cover 3, a load-bearing and placing ring 5 is provided on the outer side of the defoamer plate main body 2, and the load-bearing and placing ring 5 is supported and placed on the supporting mounting ring 4. By opening the sealed inspection cover 3, the defoamer plate main body 2 can be conveniently taken out, and the later maintenance is relatively simple and convenient. The closed cross arm plate 6 cooperates with the switch closing component 7 to isolate the upper part of the defoamer shell 1 to form a cleaning chamber. The two flushing pipes 9 cooperate with the spray component 10 to flush and clean the upper and lower sides of the defoamer plate main body 2. After the flushing is completed, the accumulated water source is used to soak and clean the defoamer plate main body 2 for a second time. The self-cleaning and sewage discharge effect is good, so that the device has an independent cleaning structure, and the wire pad can be cleaned and flushed quickly and conveniently. The later maintenance is convenient, and the maintenance cost is relatively low.

[0034] Furthermore, gas flow guide pipes 11 are provided on both sides of the demister housing 1, and the two gas flow guide pipes 11 are respectively located above and below both sides of the demister plate body 2, and a drain pipe 12 is provided at the bottom of the demister housing 1;

[0038] Furthermore, a lifting hook ring 13 is provided on the top of the carrying and placing ring 5, and the foam removal plate body 2, the supporting and mounting ring 4 and the carrying and placing ring 5 are all made of anti-corrosion materials;

[0039] By providing the lifting hook ring 13, the carrying and placing ring 5 can be directly lifted by the lifting device, so that the removal plate body 2 is convenient to take and place, has good practicality, and is convenient for later maintenance.

[0040] Furthermore, the closed cross arm plate 6 is correspondingly installed in the middle of the inner side of the demister housing 1, and the closed cross arm plate 6 is arranged directly below the demister plate body 2. The closed cross arm plate 6 and the two switch closing components 7 are spliced ​​and combined to separate the interior of the demister housing 1 into a cleaning chamber and a separation chamber.

[0041] By setting a closed cross arm plate 6 and a splicing combination of two switch closing components 7, the interior of the demister housing 1 can be divided into a cleaning chamber and a separation chamber. The cleaning chamber can be cleaned stably, and the demister plate body 2 is located inside the cleaning chamber. The demister plate body 2 can be sprayed and cleaned stably and efficiently by a spray device. At the same time, water can be accumulated inside the cleaning chamber to perform secondary immersion cleaning on the demister plate body 2, making the overall cleaning convenient.

[0042] Further, the switch closing assembly 7 includes a semicircular closing plate 71 and a telescopic hydraulic cylinder 72. The two semicircular closing plates 71 are hinged to the two sides of the interior of the demister housing 1. The two semicircular closing plates 71 are respectively matched with the two sides of the bottom of the closing cross arm plate 6. The two ends of the telescopic hydraulic cylinder 72 are hinged to the semicircular closing plates 71 and the demister housing 1. The two semicircular closing plates 71 and the closing cross arm plate 6 can form a circular shape to close the upper part of the interior of the demister housing 1. The telescopic hydraulic cylinder 72 can be hinged and telescopic as a whole.

[0043] By setting up the switch closing component 7 including the semicircular closing plate 71 and the telescopic hydraulic cylinder 72, the telescopic hydraulic cylinder 72 is operated to push the semicircular closing plate 71 and the closing cross plate 6 to close, so that the two semicircular closing plates 71 cooperate with the closing cross plate 6, the upper half of the inner side of the demister shell 1 can be completely isolated to form a cleaning chamber, thereby facilitating the cleaning operation of the demister plate main body 2 in the later stage, and the practicability is good.

[0050] The demister shell 1 is provided with a closed cross arm plate 6, and switch closing components 7 are provided on both sides of the interior. The switch closing component 7 includes a semicircular closing plate 71 and a telescopic hydraulic cylinder 72. The telescopic hydraulic cylinder 72 is operated to push the semicircular closing plate 71 and the closed cross arm plate 6 to close, so that the two semicircular closing plates 71 cooperate with the closed cross arm plate 6 to completely isolate the upper half of the inner side of the demister shell 1, and then two flushing pipes 9 cooperate with the spray assembly 10 to flush and clean the upper and lower sides of the demister plate body 2. The sewage is supported by the closed cross arm plate 6 and the semicircular closing plate 71 to form a cleaning chamber. After the internal flushing is completed, the accumulated water source is used to perform secondary immersion cleaning on the demister plate body 2.
