Description

Technical Field

[0001] This utility model belongs to the field of coke oven gas treatment, specifically a coke oven gas circulation washing and purification device. Background Technology

[0002] Coke oven gas, also known as coke oven gas, is a high-calorific-value gas with a high content of combustible components. It is also called crude coal gas or raw coal gas. It is a combustible gas produced when coke and tar products are produced by high-temperature dry distillation of several types of bituminous coal in a coke oven after the coal is blended into coking coal. It is a by-product of the coking industry.

[0003] When coke oven gas is produced, it often contains many solid components. If it is directly compressed and used, these solid impurities can easily affect the normal operation of the compressor. Therefore, coke oven gas needs to be washed and purified when it is produced. Currently, spraying is generally used to wash and purify coke oven gas. However, when using a circulating pump to circulate the washed water, the traditional direct injection nozzles are easily affected by the coke oven gas and become clogged.

[0004] Therefore, we propose a coke oven gas circulating scrubbing and purification device. Utility Model Content

[0005] The purpose of this invention is to provide a coke oven gas circulating washing and purification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coke oven gas circulating washing and purification device, comprising a washing tank, a circulating pump body placed on the right side of the washing tank, a cleaning component installed inside the washing tank, a spray cylinder fixedly embedded in the upper surface of the washing tank, an umbrella-shaped spray nozzle fixedly connected to the bottom surface of the spray cylinder, a spiral groove formed on the lower part of the inner wall of the spray nozzle, a spiral groove fixedly installed on the upper part of the inner wall of the washing tank, ceramic filler placed on the upper surface of the spiral groove, a filter screen installed on the lower part of the inner wall of the washing tank, and an auxiliary component installed on the left side of the washing tank.

[0007] Preferably, the top of the spray cylinder is fixedly connected to the output pipe of the circulating pump body, and the input end of the circulating pump body is fixedly connected to the lower part of the inner wall of the washing tank through a pipe, which is used to provide power for circulating the washing liquid inside the washing tank.

[0008] Preferably, the auxiliary component includes two fixed square rings embedded on the left side of the washing tank. Each of the two fixed square rings has a square plate that matches the size of its inner wall. A rubber block is fixedly connected to the right side of each square plate. The rubber block contacts the fixed square ring to fill the gap between the rubber block and the fixed square ring.

[0009] Preferably, the rubber block and the inner wall of the fixing square ring are interference fit, which can fill the gap between the rubber block and the fixing square ring, and make the overall sealing effect of the washing tank better.

[0010] Preferably, a set of symmetrical limit handles is fixedly connected to the left side of each of the two square plates, so that the workers can hold the limit handles and pull the square plate out from the inside of the fixed square ring.

[0011] Preferably, the cross-sectional shape of the limiting handle is the English letter "Z", and the installation position can be determined by the collision between the limiting handle and the fixed square ring.

[0012] Preferably, a ramp is fixedly connected between the upper surface of the spiral groove and the inner wall of the washing tank for guiding and diverting the washing liquid.

[0013] Preferably, the surface of the ceramic filler is coated with titanium dioxide for catalytic decomposition of tar in coke oven exhaust gas.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When the device is needed to wash and purify coke oven gas, the coke oven gas from the outside first enters the washing tank from the bottom. The gas then passes through the filter screen and the ceramic packing on the surface of the spiral groove, entering the top of the washing tank and exiting from there. At this point, the power switch connected to the circulating pump body is turned on, allowing the washing liquid inside the washing tank to circulate. The washing liquid then passes through the output pipe of the circulating pump body, which is fixedly connected to the spray nozzle. The washing liquid is then sprayed out from the output end of the spray nozzle, thus washing and purifying the coke oven gas inside the washing tank. When the coke oven gas passes through the filter screen, solid particles are filtered out. Next, the ceramic packing catalytically decomposes the tar in the coke oven gas. By setting the spray nozzle shape to be wider at the top and narrower at the bottom, with a spiral groove at the bottom, tar can be prevented from clogging the spray nozzle.

[0016] By incorporating cleaning components, the entire device can perform multi-stage washing and purification of coke oven gas, and can avoid spray blockage when spraying washing liquid.

[0017] 2. After prolonged use of the entire device, if the filter screen is to avoid excessive solid matter adhering to it, and the ceramic filler needs to be replaced after a long period of use, the operator can hold the limit handle and pull the square plate along with the rubber block out of the fixed square ring. At this time, it is easy to reach into the washing tank to clean it. After cleaning and replacement, insert the rubber block into the fixed square ring and then push the square plate into the fixed square ring. At this time, make the limit handle contact with the left side of the fixed square ring to determine that the rubber block is installed in place.

[0018] By incorporating auxiliary components, the device can be made easy to clean and can prevent water and air leaks during operation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] Example 1: A coke oven gas circulating washing and purification device includes a washing tank 3, a circulating pump body 4 placed on the right side of the washing tank 3, a cleaning component 1 installed inside the washing tank 3, a spray cylinder 5 fixedly embedded on the upper surface of the washing tank 3, an umbrella-shaped spray nozzle 6 fixedly connected to the bottom surface of the spray cylinder 5, a spiral groove 7 opened on the lower part of the inner wall of the spray nozzle 6, a spiral groove 7 fixedly installed on the upper part of the inner wall of the washing tank 3, a ceramic filler 9 placed on the upper surface of the spiral groove 7, a filter screen 10 installed on the lower part of the inner wall of the washing tank 3, and an auxiliary component 2 installed on the left side of the washing tank 3.

[0029] The top of the spray cylinder 5 is fixedly connected to the output pipe of the circulating pump body 4, and the input end of the circulating pump body 4 is fixedly connected to the lower part of the inner wall of the washing tank 3 through a pipe, which is used to provide power for circulating the washing liquid inside the washing tank 3.

[0030] The cross-sectional shape of the limit handle 14 is the English letter "Z". The installation position can be determined by the collision between the limit handle 14 and the fixed square ring 13.

[0031] A ramp 8 is fixedly connected between the upper surface of the spiral groove 7 and the inner wall of the washing tank 3, which is used to guide and drain the washing liquid.

[0032] The surface of the ceramic filler 9 is coated with titanium dioxide for catalytic decomposition of tar in coke oven exhaust gas.

[0033] When the device is needed to wash and purify coke oven gas, the coke oven gas from the outside first enters the washing tank 3 from the bottom. At this time, the coke oven gas will enter the top of the washing tank 3 through the filter screen 10 and the ceramic packing 9 on the surface of the spiral groove 7, and then be discharged from the top of the washing tank 3. At this time, the power switch connected to the circulating pump body 4 is turned on, which allows the washing liquid inside the washing tank 3 to circulate. The washing liquid will then pass through the output pipe of the circulating pump body 4 and be fixedly connected to the spray cylinder 5. The washing liquid will then be sprayed out from the output end of the spray nozzle 6, which can wash and purify the coke oven gas inside the washing tank 3. When the coke oven gas passes through the filter screen 10, solid particles will be filtered out. Then, the ceramic packing 9 will catalytically decompose the tar in the coke oven gas. By setting the shape of the spray nozzle 6 to be wider at the top and narrower at the bottom and having a spiral groove 7 at the bottom, tar can be prevented from clogging the spray cylinder 5.

[0034] By setting up cleaning component 1, the entire device can perform multi-stage washing and purification of coke oven gas, and can avoid spray blockage when spraying washing liquid.

[0035] In the second embodiment, the auxiliary component 2 includes two fixed square rings 13 embedded on the left side of the washing tank 3. The inside of each fixed square ring 13 is fitted with a square plate 11 that matches the size of its inner wall. A rubber block 12 is fixedly connected to the right side of each square plate 11. The rubber block 12 contacts the fixed square ring 13 to fill the gap between the rubber block 12 and the fixed square ring 13.

[0036] The rubber block 12 and the inner wall of the fixed square ring 13 are interference fit, which can fill the gap between the rubber block 12 and the fixed square ring 13, so that the overall sealing effect of the washing tank 3 is better.

[0037] A set of symmetrical limit handles 14 are fixedly connected to the left side of each of the two square plates 11, which makes it easy for the staff to hold the limit handles 14 and pull the square plate 11 out from the inside of the fixed square ring 13.

[0038] When the entire device has been used for a long time, if the filter screen 10 is to avoid excessive adhesion of solid matter, and the ceramic filler 9 needs to be replaced after long-term use, the operator can hold the limit handle 14 to pull the square plate 11 along with the rubber block 12 out from the inside of the fixed square ring 13. At this time, it is easy to reach into the inside of the washing tank 3 to clean it. After cleaning and replacement, insert the rubber block 12 into the inside of the fixed square ring 13 and then push the square plate 11 into the inside of the fixed square ring 13. At this time, make the limit handle 14 contact the left side of the fixed square ring 13 to determine that the rubber block 12 is installed in place.

[0039] By setting auxiliary component 2, the device can be made easy to clean and can also avoid water and air leakage when in operation.
