If not cleaned, the nozzles will become clogged, affecting the purification effect.

[0005] Therefore, there is an urgent need to test coke oven gas purification devices to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that nozzles are easily clogged due to the adhesion of impurities, which affects the desulfurization effect on coke oven gas. Therefore, an experimental coke oven gas purification device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An experimental coke oven gas purification device includes a spray box. A top box is fixedly installed on the top of the spray box, and a base box is installed on the bottom of the spray box. Two spray mechanisms are installed inside the spray box from bottom to top. Each spray mechanism includes a second uniform distribution plate and a spiral spray pipe installed on the second uniform distribution plate. Multiple nozzle assemblies are evenly installed at the bottom of the spiral spray pipe. Each nozzle assembly includes a nozzle communicating with the spiral spray pipe.

The top of the spray seat is connected to the inner side of the nozzle through multiple return springs. Multiple spray nozzles are opened on the outer side of the spray seat. A scraper is fixedly installed at the bottom end of the sleeve.

[0009] As a preferred technical solution of this application, a conical cylinder is fixedly installed at the bottom of the top box, and a baffle is installed inside the conical cylinder. The baffle is conical, and the top of the conical cylinder is connected to an air outlet pipe installed on one side of the top box.

[0010] As a preferred technical solution of this application, a support plate is fixedly installed at the bottom end of the conical cylinder, and the bottom end of the conical cylinder is fixedly connected to the inner side of the spray box through the support plate.

[0011] As a preferred technical solution of this application, an air inlet pipe is installed on one side of the base box, a drain pipe is installed on the other side of the base box, and a suction head is installed on one end of the drain pipe located inside the base box.

[0012] As a preferred technical solution of this application, a first uniformly distributed plate is installed at an angle inside the base box.

[0013] As a preferred technical solution of this application, a liquid inlet pipe is fixedly installed at one end of the spiral spray pipe, and the liquid inlet pipe passes through the spray box.

[0014] As a preferred technical solution of this application, a support rod is installed on the spiral spray pipe, and the spiral spray pipe is connected to the inner wall of the spray box through the support rod.

[0015] Compared with the prior art, this utility model provides an experimental coke oven gas purification device, which has the following beneficial effects:

[0016] 1. The coke oven gas purification device in this experiment uses a spray seat, which is connected to the nozzle by a return spring. Multiple return springs can drive the spray seat to reset after spraying is stopped. During the reset process, the outer surface of the spray seat is cleaned by a scraper at the bottom of the sleeve, which helps to reduce the adhering substances on the outside of the spray seat and effectively reduce clogging. This solves the problem in the prior art that the nozzle is easily clogged by impurities, which affects the desulfurization effect on coke oven gas.

[0017] 2. The coke oven gas purification device in this experiment uses a conical cylinder and baffles inside the conical cylinder. After the gas enters the conical cylinder, it collides with the baffles, changing the airflow direction. Liquid droplets are captured by impacting the surfaces of these obstacles due to inertia, which helps to reduce the liquid content in the purified gas. Attached Figure Description

Two spray mechanisms are installed inside the spray box 3 from bottom to top. The spray mechanism includes a second uniform distribution plate 20 and a spiral spray pipe 12 installed on the second uniform distribution plate 20. One end of the spiral spray pipe 12 is fixedly installed with a liquid inlet pipe 4, which passes through the spray box 3. Multiple nozzle assemblies are evenly installed at the bottom of the spiral spray pipe 12. Each nozzle assembly includes a nozzle 14 communicating with the spiral spray pipe 12. A sleeve 18 is fixedly installed at the bottom of the nozzle 14. An inner cylinder 15 is slidably installed inside the sleeve 18. A spray seat 17 is fixedly installed at the bottom end of the inner cylinder 15. The top of the spray seat 17 is connected to the inner side of the nozzle 14 through multiple return springs 16. Multiple spray ports are opened on the outer side of the spray seat 17, and the liquid inlet pipe... 4. Connect an external liquid supply pump. The pumped liquid drives the inner cylinder 15 and the spray seat 17 to descend, exposing multiple spray nozzles on the spray seat 17 and spraying the liquid into the interior of the spray box 3. After spraying stops, the spray seat 17 resets under the action of the return spring 16 and enters the sleeve 18. A scraper is fixedly installed at the bottom of the sleeve 18. During the reset process of the spray seat 17, the outer surface of the spray seat 17 is scraped by the sleeve 18 to remove the adhering substances and reduce blockage. The two sets of spraying mechanisms can be started simultaneously or alternately as needed, so that the outer surface of the spray seat 17 can be cleaned by the scraper on the sleeve 18 after spraying stops. A support rod 13 is installed on the spiral spray pipe 12. The spiral spray pipe 12 is connected to the inner wall of the spray box 3 through the support rod 13 to improve the stability of the spiral spray pipe 12 during use.

[0028] Reference Figure 2 and Figure 3 Furthermore, a conical cylinder 9 is fixedly installed at the bottom of the top box 5, and a support plate 8 is fixedly installed at the bottom end of the conical cylinder 9. The bottom end of the conical cylinder 9 is fixedly connected to the inside of the spray box 3 through the support plate 8. A baffle 10 is installed inside the conical cylinder 9. The baffle 10 is conical, and there are two baffles 10 installed opposite each other with a height difference. After the gas is sprayed, the liquid inside the baffle 10 collides with it, which helps to reduce the liquid in the baffle and makes subsequent processing more convenient. The top of the conical cylinder 9 is connected to the air outlet pipe 6 installed on one side of the top box 5, and the purified gas is discharged through the air outlet pipe 6.

A first uniform distribution plate 11 is installed at an angle inside the base box 1. The sprayed liquid collides with the first uniform distribution plate 11 and comes into contact with the gas entering the base box 1 first. The mixing effect is improved by the first uniform distribution plate 11, and the gas entering through the air inlet pipe 2 can also be initially evenly distributed by the first uniform distribution plate 11, thereby improving the mixing efficiency of the gas entering and the sprayed liquid.

[0030] Specifically, when the coke oven gas purification device in this experiment is working: the coke oven gas is introduced into the base box 1 through the inlet pipe 2, and then mixed with the sprayed liquid through the first uniform distribution plate 11 before entering the spray box 3. After being desulfurized by two sets of spraying mechanisms, it enters the conical cylinder 9. The conical cylinder 9 reduces the liquid carried by the gas, and then it is discharged through the outlet pipe 6.
