Description

Technical Field

[0001] This utility model relates to the field of desulfurization equipment technology, specifically to a purification and desulfurization device for coal gas emissions. Background Technology

[0002] Most of the sulfur in coal gas exists in the form of H2S. After the coal gas is burned, H2S is converted into SO2. Excessive SO2 content in the air will form local acid rain, which will harm people's living environment. Therefore, coal gas needs to be desulfurized before it is released.

[0003] For example, the authorized patent with announcement number CN213835188U (a gas desulfurization device) includes an air inlet pipe, a cooling and cleaning mechanism, a desulfurization mechanism, a filtering mechanism, and a driving mechanism. The upper surface of the cooling and cleaning mechanism body is provided with a through hole. One end of the air inlet pipe body is connected to the through hole. One end of the first air guide pipe is connected to one side surface of the cooling and cleaning mechanism body. One end of the second air guide pipe is connected to one side surface of the filtering mechanism body. One end of each of the two first shock-absorbing springs is connected to the lower surface of the cooling and cleaning mechanism body. One end of each of the two second shock-absorbing springs is connected to the lower surface of the filtering mechanism body.

[0004] While the existing technologies described above can dissolve dust in coal gas in water, they also generate a large number of gas bubbles when the coal gas is introduced into the desulfurization tank, which leads to unstable desulfurization of the coal gas. Furthermore, the content of desulfurizing agent inside the desulfurization tank will gradually decrease, affecting the continuous desulfurization of the coal gas. Therefore, there is an urgent need in the market to develop a purification and desulfurization device for coal gas emissions to help people solve the existing problems. Utility Model Content

[0032] Working principle: During use, coal gas flows into the gas delivery pipe 2 through the external delivery pipeline and then into the filter box 9. The filter plate 10 filters the coal gas, removing dust and impurities. The coal gas then flows into the distribution box 12 through the delivery pipe 11, and then out through different outlets 23 on the distribution box 12, allowing the coal gas to rise evenly into the packing box 15. The purification packing 16 ensures sufficient contact with the coal gas for desulfurization and purification. Simultaneously, liquid desulfurizing agent is delivered through the liquid supply pipe 18 and sprayed through the atomizing nozzle 19, allowing the desulfurizing agent to enter the purification packing 16, achieving continuous desulfurization of the coal gas. After being dehumidified by the dehumidifier 21, the coal gas flows into the top box 3, where activated carbon particles inside the activated carbon box 22 adsorb the desulfurized coal gas. Finally, the coal gas is output through the output pipe 4.
