Description

Technical Field

[0001] The utility model relates to the field of gas purification washing towers, in particular to a washing tower for acetylene replacement gas using a calcium carbide process. Background Art

[0002] In the existing calcium carbide-based PVC production industry, acetylene generators produce acetylene gas through the hydrolysis reaction of calcium carbide. Calcium carbide is intermittently fed into the generator through a storage hopper. To prevent air from coming into contact with acetylene gas during the discharge process, the hopper must be purged with nitrogen after each discharge. However, this purged gas, containing impurities such as calcium carbide, is then discharged. This impurity-laden gas not only pollutes the environment but also wastes raw materials and increases energy consumption.

[0003] Therefore, a washing tower for acetylene replacement gas produced by the calcium carbide process is provided to solve the problems raised in the above background technology. Utility Model Content

[0009] The beneficial effect of adopting the above further solution is: starting the water pump to discharge water into the vortex spray group through the water outlet pipe. After being sprayed by the vortex spray group, the water enters the water pump through the water inlet pipe, forming a circulating spray, thereby improving work efficiency.

[0010] Furthermore, the water inlet pipe is provided with a water inlet valve, and the water outlet pipe is provided with a water outlet valve.

[0011] The beneficial effect of adopting the above further solution is that the staff can control the working conditions of the water inlet pipe and the water outlet pipe through the water inlet valve and the water outlet valve.

[0031] The replaced mixed gas enters the scrubber 1 from the air inlet 3 and moves evenly from bottom to top in the scrubber 1 after passing through the distributor 2. The circulating spray device 5 is activated to spray the replaced mixed gas in the scrubber 1.

[0034] On the basis of the above scheme, the circulating spray device 5 includes a water pump 501, a water inlet pipe 502, a water outlet pipe 503 and a vortex spray group 504, one end of the water inlet pipe 502 is connected to the bottom of the washing tower 1, the other end of the water inlet pipe 502 is connected to the inlet of the water pump 501, the outlet of the water pump 501 is connected to one end of the water outlet pipe 503, the other end of the water outlet pipe 503 is connected to the vortex spray group 504, the vortex spray group 504 is fixedly connected to the washing tower 1, and the vortex spray group 504 is arranged in the washing tower 1 and is located above the distributor 2.

[0035] Start the water pump 501 and discharge water into the vortex spray group 504 through the water outlet pipe 503. The water sprayed by the vortex spray group 504 enters the water pump 501 through the water inlet pipe 502, forming a circulating spray to improve work efficiency.

[0036] Specifically, in this embodiment, the water inlet pipe 502 is horizontally arranged, and the water outlet pipe 503 is vertically arranged. The water inlet pipe 502 and the water outlet pipe 503 can also be arranged to be inclined according to actual needs.

[0037] On the basis of the above solution, a water inlet valve 505 is provided on the water inlet pipe 502 , and a water outlet valve 506 is provided on the water outlet pipe 503 .

[0038] The staff can control the working conditions of the water inlet pipe 502 and the water outlet pipe 503 through the water inlet valve 505 and the water outlet valve 506.

[0039] On the basis of the above solution, there are multiple vortex spray groups 504 , which are vertically spaced apart, and each of the vortex spray groups 504 is connected to the water outlet pipe 503 .

[0040] The multiple vortex spray groups 504 spray the replaced mixed gas, which can improve the wettability of the mixed gas containing impurities, thereby improving the mud washing effect.

[0041] Specifically, there may be three, four, or five vortex spray groups 504. The multiple vortex spray groups 504 are all equidistantly arranged to better contact the mixed gas.

[0042] Based on the above solution, the vortex spray groups 504 are three groups.
