Description

Technical Field

[0001] This utility model relates to the field of chemical exhaust gas treatment, and in particular to a device for treating exhaust gas from chemical product preparation. Background Technology

[0002] During the production of chemical products, a large amount of chemical exhaust gas is generated. Chemical exhaust gas refers to the toxic and harmful gases discharged from chemical plants during chemical production. Chemical exhaust gas often contains a wide variety of pollutants with complex physical and chemical properties and varying degrees of toxicity, seriously polluting the environment and affecting human health. The composition of chemical exhaust gas varies greatly between different chemical production industries. For example, the exhaust gas from the chlor-alkali industry mainly contains chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene, etc.; the exhaust gas from the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc.; and there is also automobile exhaust, etc.

[0003] In existing technologies, the treatment of chemical exhaust gas mostly involves first filtering larger impurities in the exhaust gas through a filter screen, and then directly absorbing harmful substances in the exhaust gas through a treatment liquid. However, chemical exhaust gas is mostly high-temperature gas, and spraying the treatment liquid directly without cooling it will result in poor absorption effect of the treatment liquid. In addition, the treatment liquid is easily heated into a gaseous state by the high-temperature exhaust gas and discharged together, making the existing chemical exhaust gas treatment devices ineffective.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a chemical product preparation tail gas treatment device to solve the aforementioned technical defects.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A chemical product preparation tail gas treatment device includes a treatment box, an air inlet square pipe fixedly connected to the lower side of one side of the treatment box, an air pump fixedly installed on the upper side of one side of the treatment box by bolts, and an inclined mounting frame fixedly installed inside the upper part of the treatment box, and a filter frame slidably connected inside the inclined mounting frame.

[0008] The filter frame is equipped with a filter screen. A connecting pipe with internal communication is fixedly provided on the top of one side of the processing box. A cooling treatment mechanism is provided at the other end of the connecting pipe. The cooling treatment mechanism includes a processing box, and a partition is fixedly provided in the middle section of the interior of the processing box.

[0010] Preferably, a discharge chute is provided above the connection between the inclined partition and the processing box, and a waste box is provided on the outside of the processing box, with a fixedly connected card plate on the side of the waste box near the processing box.

[0011] Preferably, the inclined mounting bracket is arranged parallel to the inclined partition plate 2, an integrally formed handle is fixedly provided on one side of the filter frame, a fixedly connected through pipe is provided inside the processing box 1, an array of air blowing pipes is fixedly provided below the through pipe, the air blowing pipes are connected to the inside of the through pipe, and the through pipe is connected to the inside of the air outlet of the air pump.

[0012] Preferably, the second processing box is fixedly connected to the connecting pipe and internally connected. The partition divides the interior of the second processing box into an upper chamber and a lower chamber. An arc-shaped connecting pipe is fixedly connected between the upper chamber and the lower chamber. A flow equalization plate is fixedly installed on the top of the second processing box by bolts.

[0013] Preferably, a water inlet pipe is fixedly connected and internally communicated above the flow equalization plate, and an array of water spray pipes is fixedly arranged at the bottom of the flow equalization plate. The lower end of the water spray pipes passes through the second treatment box and extends into the interior of the second treatment box.

[0014] Preferably, a baffle is fixedly provided on one side of the inner wall of the upper chamber of the second treatment box, and a sprinkler is fixedly connected in the lower chamber of the second treatment box. An array of sprinkler holes is opened below the sprinkler, and an inlet pipe is fixedly provided at one end of the sprinkler.

[0015] The sprinkler is also equipped with a slidingly connected activated carbon box above it. A drain pipe is fixedly installed on one side of the bottom of both the upper and lower chambers. An exhaust pipe is fixedly connected to the bottom of the other side of the treatment box, and the exhaust pipe is connected to the interior of the treatment box.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model connects the air inlet square pipe to the exhaust pipe of the chemical exhaust gas. The chemical exhaust gas enters the treatment box one through the air inlet square pipe, and then passes through the gap between the inclined baffle one and the inclined baffle two, and then passes through the filter screen for filtration. At this time, larger impurities are left below the filter screen or slide down into the waste box through the inclined baffle two and the inclined baffle one. When the filter screen begins to get clogged, the air pump is started to blow air through the air pipe to clean the filter screen. After the exhaust gas passes through the filter screen, it enters the treatment box two through the connecting pipe. At this time, the water spray pipe starts to spray water to cool down the exhaust gas and simultaneously adsorb and treat the fine dust in the exhaust gas.

[0018] After cooling, the exhaust gas enters the lower chamber through the arc-shaped connecting pipe, and then undergoes adsorption treatment at the activated carbon box. The adsorbed exhaust gas then enters below the sprinkler, where treatment liquid is added to the sprinkler through the liquid inlet pipe for further treatment of the exhaust gas. The treated exhaust gas is then discharged through the exhaust pipe. Before using the treatment liquid to treat the exhaust gas, this device first removes impurities of all sizes from the exhaust gas through a filter, water spraying, and activated carbon adsorption, and also cools the exhaust gas to reduce the amount of treatment liquid used, thereby reducing the cost of exhaust gas treatment and improving the treatment efficiency.

[0037] After being filtered by filter 21, the exhaust gas enters the treatment chamber 31 through connecting pipe 22. At this time, water spraying begins at water spray pipe 34 to cool the exhaust gas and treat fine dust. The cooled exhaust gas enters the lower chamber through arc-shaped connecting pipe 37, and then undergoes adsorption treatment at activated carbon box 38. The adsorbed exhaust gas enters below water sprayer 39. At this time, treatment liquid is added into water sprayer 39 through liquid inlet pipe to further treat the exhaust gas.
