Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, and specifically to a waste gas treatment system. Background Art

[0002] In the prior art, explosives are destroyed by incineration in an explosion-proof furnace. When the explosives in the explosion-proof furnace reach a certain temperature, they will explode. A large amount of high-pressure gas is generated by the explosion, and a large amount of waste gas is also generated. The waste gas generally contains certain harmful components, especially when dealing with explosives that are toxic in themselves. Therefore, it is necessary to treat the waste gas to prevent the waste gas from escaping into the air and polluting the environment. At the same time, a large amount of high-pressure gas and explosion residue will be generated when the explosive explodes, and the high-pressure gas will carry the residue everywhere. The residue accumulates in the pipeline, which can easily cause blockage of the gas pipeline. Therefore, it is necessary to provide a waste gas treatment system that can handle the waste gas and residue generated by the explosives to avoid air pollution. Utility Model Content

Then the remaining exhaust gas is guided by the air guide, discharged from the cyclone dust collector, and enters the next treatment process. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment 1

[0045] Reference Figure 1 and Figure 3 , which is the first embodiment of the utility model, proposes an exhaust gas treatment system.

[0046] In this embodiment, the buffer tank 1, the cyclone dust collector 2 and the air guide 5 are specifically included, and the debris collecting part 6 and the partition plate 23 are also included; when in use, the explosive explodes in the explosion-proof furnace, and the waste gas generated enters the buffer tank 1. The buffer tank 1 has a large volume. With the effect of the increased volume of the buffer tank 1, the waste gas pressure is reduced, and the waste gas has a flow and pressure stabilizing effect. At the same time, the buffer tank 1 can precipitate explosive fragments and large particles; then the pressure-reduced and stabilized waste gas enters the cyclone chamber 3 The exhaust gas enters the cyclone chamber 3 along the direction tangent to the inner wall of the cyclone chamber 3. With the help of the cylindrical cyclone chamber 3, the exhaust gas rotates in the cyclone chamber 3. As the exhaust gas rotates, the solid residue in the exhaust gas is affected by its own gravity and gradually settles to the bottom of the cyclone chamber 3 along the spiral moving direction, driving the partition plate 23 to slide, connecting the cyclone chamber 3 and the collection chamber 7, and the solid residue falls into the collection chamber 7, completing the separation and collection of the solid residue in the exhaust gas. Then the remaining exhaust gas is guided by the air guide 5, discharged from the cyclone dust collector 2, and enters the next treatment process.

[0047] The number of partition plates 23 is preferably two, one partition plate 23 is used for connecting or canceling the connection between the cyclone chamber 3 and the miscellaneous collecting chamber 7, and the second partition plate 23 is located at the bottom of the miscellaneous collecting chamber 7. When the solid residue in the miscellaneous collecting chamber 7 accumulates to a certain extent, the gas in the miscellaneous collecting chamber 7 is ventilated with the help of the built-in air inlet and air outlet of the miscellaneous collecting chamber 7 until the gas in the miscellaneous collecting chamber 7 is completely replaced, and the replaced gas is introduced into the outlet of the air guide 5 to continue the subsequent exhaust gas treatment. At this time, the second partition plate 56 is opened to release the solid residue in the miscellaneous collecting chamber 7, and then the second partition plate 23 is closed to wait for the next release of the solid residue.

[0048] Embodiment 2

[0049] Reference Figure 1 and Figure 3 , which is the second embodiment of the utility model. On the basis of the first embodiment, this embodiment further adds a burner 8 and a heat exchange quenching tower 9; when in use, the gas discharged from the cyclone dust collector 2 enters the burner 8 for combustion. The burner 8 can use diesel, natural gas or plasma heating to provide combustion, which is used to remove toxic gas components, carbon monoxide, hydrogen and dioxin precursors in the exhaust gas, purify the exhaust gas, and obtain high-temperature exhaust gas; then the high-temperature exhaust gas is cooled by means of the heat exchange quenching tower 9 to facilitate subsequent gas treatment. The cooling form of the heat exchange quenching tower 9 can be selected from one or a combination of wall heat exchange, spray or spray.

[0050] Embodiment 3

[0051] Reference Figure 1 and Figure 3 , which is the third embodiment of the utility model, is based on the second embodiment, and further adds a bag filter 10, an electrostatic precipitator 11, a photo-oxidation activated carbon integrated machine 12, an induced draft fan 13, a deacidification washing tower 14 and a low-temperature denitrification tower 15; wherein, a treatment process is added between the bag filter 10 and the heat exchange quenching tower 9, a filler treatment, and activated carbon is used to adsorb heavy metals to prevent heavy metals from flowing into the subsequent treatment process.

[0052] The bag filter 10 and the electrostatic precipitator 11 can be used either alone or together; the two can be used together for explanation. When used, the cooled exhaust gas will enter the bag filter 10 and the electrostatic precipitator 11 in turn; the bag filter 10 is used to adsorb dust and activated carbon powder, and the electrostatic precipitator 11 uses the ionization adsorption effect of the high-voltage electric field to purify small particles of dust; the exhaust gas after two dust removals enters the photo-oxidation activated carbon integrated machine 12, and the UV photolysis and oxidation module in the photo-oxidation activated carbon integrated machine 12 is used to degrade organic exhaust gases such as alcohols, aldehydes, and benzene; then the activated carbon filter is used to re-adsorb the organic exhaust gas in the exhaust gas to improve the exhaust gas purification effect. In the process, the exhaust gas is driven to flow in an orderly manner by the negative pressure provided by the induced draft fan 13.

[0053] The waste gas is then introduced into the deacidification scrubber 14 and the low-temperature denitration tower 15 in sequence, and the acidic gases such as SO are removed in the deacidification scrubber 14 by spraying with an alkaline solution. X 、N X O, H X S, HCI, etc.; and then use the low-temperature denitrification tower 15 to remove N X O, complete the purification of exhaust gas.

[0054] Embodiment 4

On the basis of the first embodiment, this embodiment further adds an air intake pipe 16, a filter element 18, a filter plate 20 and a debris collection piece 22, wherein the diameter reducing portion 17 on the air intake pipe 16 changes in size from small to large. With the help of the diameter reducing portion 17, the high-pressure gas generated by the explosion-proof furnace is initially depressurized to reduce the pressure drop of the gas in the buffer tank 1; the filter plate 20 is used to intercept large fragments generated by the explosion, and the filter plate 20 is inclined. The intercepted large fragments settle into the debris collection piece 22 under the action of their own gravity. With the help of the filter plate 20, the filtering and collection of large fragments are completed, and the separation and classification of solid residues are achieved at the same time.
