Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for a gas steam boiler. Background Technique

[0002] A gas steam boiler is a boiler that uses gas as fuel. It generates heat by burning gas, heats water to generate steam, and then utilizes the high temperature and high pressure of the steam to drive equipment or provide heat energy. Gas steam boilers are usually used in industrial production, heating systems, power generation and other fields. When burning gas, gas steam boilers will generate waste gas, which contains some harmful substances and pollutants, such as sulfur dioxide, nitrogen oxides, particulate matter, etc. In order to protect the environment and human health, these waste gases need to be treated and purified.

[0003] After retrieval, the patent with the Chinese patent authorization number CN216604575U discloses a waste gas treatment device for a gas steam boiler, including a treatment box. An electric heating plate is provided on the inner wall of the bottom of the treatment box. Support blocks are respectively provided on the inner walls of the opposite sides of the treatment box. A filter screen is provided between the upper walls of the two support blocks. A water pump is provided at the bottom of the outer wall of one side of the treatment box. The input end of the water pump is communicated with the treatment box. A water spray pipe is provided on the inner wall of the treatment box above the filter screen. A plurality of atomizing nozzles are provided on the bottom wall of the water spray pipe. The output end of the water pump is communicated with the water spray pipe through a pipeline passing through the side wall of the treatment box. Support blocks two are respectively provided on the inner walls of the two sides of the treatment box above the water spray pipe. The following deficiencies exist in the waste gas treatment device for a gas steam boiler in the above patent: 1. When the device evaporates water to form water vapor and rises, and the water vapor descends to remove dust from the soot, both pass through the same filter plate. This way, the movement paths are relatively conflicting, which leads to relatively crowded filter channels of the filter plate, thus affecting the filtration speed; 2. The device only filters the soot once through a filter plate, and the overall filtration quality is poor. As a result, a large part of the soot is carried by the water on the filter plate into the water storage space, polluting the circulating water, reducing the number of times of water circulation, and at the same time, the water pump is blocked after a long time of use and needs to be cleaned or repaired. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that the same filter plate is used for both the water vapor and the soot to descend, which affects the descending speed of the soot, and the soot is only filtered once through the filter plate, which easily pollutes the circulating water and causes the water pump to be blocked, and to propose a waste gas treatment device for a gas steam boiler.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A waste gas treatment device for a gas steam boiler, including a treatment box, the top wall of the treatment box is fixedly connected with an arc-shaped plate, and further includes:

A handle is fixedly connected to the outer wall of the filter plate, a second inclined plate is fixedly connected to the outer wall of the guiding block, and a first inclined plate is fixedly connected to both the inner wall of the processing box and the outer wall of the special-shaped block;

[0010] The evaporation and rising assembly is arranged on the inner wall of the processing box;

[0011] The spraying assembly is arranged on the outer wall of the processing box.

[0012] As a preferred technical solution of the present application, the evaporation and rising assembly includes a special-shaped block fixedly connected to the inner wall of the processing box. The inner wall of the special-shaped block is provided with evenly distributed water outlets, and the outer wall of the special-shaped block is fixedly connected with evenly distributed arc-shaped covers.

When the water is heated and evaporated by the heating plate, it will rise through the shape of the special-shaped block and the arc-shaped plate. At the same time, it is divided by the first inclined plate, one-third of the filter plate and the space for filtering soot, so that the dust reduction filtration and the steam rising do not affect each other, thus eliminating the influence of water vapor on the soot falling filtration, improving the speed of the soot falling filtration, and solving the problem in the prior art that the water vapor and the soot falling both pass through the same filter plate, which affects the soot falling speed;

[0018] 2. The waste gas treatment device for the gas steam boiler extends the path of the soot passing through by setting the first inclined plate and the second inclined plate, and conducts three filtrations through the same filter plate, improving the filtration quality, avoiding incomplete filtration of soot from polluting the circulating water, prolonging the usage times of the circulating water, and reducing the risk of water pump blockage, thus solving the problems in the prior art that the soot is only filtered once through its filter plate, which is easy to pollute the circulating water and cause water pump blockage.

[0028] A heating plate 15, fixedly connected to the inner wall of the treatment tank 1, through which water is evaporated and moves upward;

[0029] A fan 6, fixedly connected to the top wall of the treatment tank 1, and the air inlet end of the fan 6 is fixedly connected to the inner wall of the treatment tank 1, through which the filtered soot is conveniently discharged;

[0030] A circulating filtration assembly, the circulating filtration assembly includes a guide block 12, and two to three groups of guide blocks 12 are provided. A filter plate 13 is slidably connected to the inner wall of the guide block 12, and the filter plate 13 is slidably connected to the inner wall of the treatment tank 1. A handle 14 is fixedly connected to the outer wall of the filter plate 13. By pulling the handle 14, the filter plate 13 can be pulled outwards to facilitate cleaning or replacement of the filter plate 13. A second inclined plate 20 is fixedly connected to the outer wall of the guide block 12. First inclined plates 11 are fixedly connected to both the inner wall of the treatment tank 1 and the outer wall of the special-shaped block 10. Through the first inclined plates 11 and the second inclined plate 20, the filter plate 13 is divided into four parts of space, so that the soot passes through the filter plate 13 three times, that is, three filtrations are carried out, reducing the proportion of soot polluting water resources and increasing the number of times of using circulating water;

[0031] An evaporation and rising assembly, arranged on the inner wall of the treatment tank 1;

[0032] A spraying assembly, arranged on the outer wall of the treatment tank 1.

[0033] Refer to Figure 2 and Figure 4 The evaporation and rising assembly includes a special-shaped block 10 fixedly connected to the inner wall of the treatment tank 1. The inner wall of the special-shaped block 10 is provided with uniformly distributed water outlets 17. The outer wall of the special-shaped block 10 is fixedly connected with uniformly distributed arc-shaped covers 18. Through the arc-shaped covers 18, it can be avoided that the water sprayed by the atomizing nozzle 8 carries unpurified soot and enters the circulating water through the water outlet 17.

[0034] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0035] Refer to Figure 1 and Figure 4 An air inlet pipe 9 is fixedly connected to the inner wall of the treatment tank 1, and a water inlet pipe 3 is fixedly connected to the inner wall of the treatment tank 1. One end of the water inlet pipe 3 away from the treatment tank 1 is rotatably connected with a sealing cover 4. The required amount of water is injected through the water inlet pipe 3 and the water inlet pipe 3 is covered by the sealing cover 4 to achieve the sealing effect.

[0036] Refer to Figure 4 An activated carbon filter screen 19 is fixedly connected to the inner wall of the treatment tank 1. A small amount of soot is filtered through the activated carbon filter screen 19 to improve the overall waste gas treatment effect.

[0037] Specifically, when this waste gas treatment device for a gas-fired steam boiler is in operation / use: First, water is injected through the water inlet pipe 3 and the sealing cover 4 is closed on the water inlet pipe 3. Then, the water injected into the treatment tank 1 is heated by the heating plate 15 to form water vapor and move upward. The water vapor will be blocked by the special-shaped block 10, the first inclined plate 11 and the filter plate 13, so as to prevent the water vapor from entering above the treatment tank 1 through the first inclined plate 11. Therefore, the water vapor flows into the space to be dust-reduced through the inclined surface of the special-shaped block 10 and the arc-shaped plate 16 towards the water outlet 17. At the same time, the soot enters the treatment tank 1 through the air inlet pipe 9 and meets the water vapor to achieve dust reduction. The particles in the soot freely fall through the water vapor and flow onto the first inclined plate 11 and the second inclined plate 20 through the inclined surface at the top of the special-shaped block 10. There are two groups of the first inclined plate 11 and the second inclined plate 20 respectively, so that the dust-reduced soot passes through the filter plate 13 three times, that is, three times of filtration. The filtered water flows back into the circulating water again. At the same time, the water is pumped out by the water pump 2 and flows into the pipeline 5 through the water outlet end, and finally flows into the spray plate 7, and the water is sprayed through the atomizing nozzles 8 for auxiliary dust reduction. The arc-shaped cover 18 can effectively prevent the non-dust-reduced soot from entering the circulating water through the water outlet 17. Part of the smoke will move upward through the gap between the treatment tank 1 and the spray plate 7 and is further filtered through the activated carbon filter screen 19. Finally, the treated smoke is exhausted by the blower 6.

[0038] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
