Description
Technical Field
The utility model relates to a carbon fiber environmental protection technology field especially relates to an acrylonitrile exhaust treatment device.
Background
Acrylonitrile is the most important raw and other materials in the PAN base carbon fiber preparation process, and acrylonitrile has volatile gas in the airtight environment of storage tank, because the rising of material liquid level when the acrylonitrile tank car is unloaded, volatile gas can enter into to follow-up processing system along with the breather valve in, leads to the stage nature to increase system load, for the treatment effeciency that improves follow-up exhaust-gas treatment, guarantees that exhaust-gas treatment is up to standard, so when the acrylonitrile tank car is unloaded waste gas in the storage tank effectively collect the processing. When the conventional acrylonitrile storage tank is used, the discharged gas is not treated independently but directly enters a gas treatment tower for mixed treatment, so that the phenomenon of over standard discharge can occur; or the acrylonitrile storage tank is treated by the catalytic tower and the spray tower when in use, because the residence time of the acrylonitrile gas in the pipeline is short, the reaction time is short, the treatment effect is not ideal, and certain defects exist.
SUMMERY OF THE UTILITY MODEL
Based on the problem in the background art, the utility model aims to provide an acrylonitrile exhaust treatment device improves the exhaust-gas treatment effect.
Realize the utility model discloses the technical scheme of purpose does: an acrylonitrile waste gas treatment device comprises a medicine barrel filled with waste gas treatment liquid, wherein the top of the medicine barrel is provided with an air inlet pipe, an exhaust pipe and a medicine adding port; one end of the air inlet pipe is arranged below the liquid level of the treatment liquid, one end of the air outlet pipe is arranged above the liquid level of the treatment liquid, a bypass pipe is arranged between the air inlet pipe and the air outlet pipe which are positioned above the medicine barrel, and valves are arranged on the air inlet pipe, the air outlet pipe and the bypass pipe; a plurality of air outlet holes are arranged at the end of the air inlet pipe positioned in the medicine barrel; the explosive barrel top is equipped with agitator motor, and agitator motor has connected gradually (mixing) shaft and stirring rake, and (mixing) shaft and stirring rake are located the explosive barrel inside, and the side intercommunication of explosive barrel has the board-like level gauge of turning over.
Compared with the prior art, the beneficial effects of the utility model reside in that: when the device unloads an acrylonitrile tank car, anhydrous sodium sulfite and water are added into the medicine barrel for dilution, so that acrylonitrile gas and sodium sulfite liquid in the medicine barrel are degraded after fully reacting and are discharged to a subsequent waste gas treatment system, the waste gas treatment effect is improved, and the waste gas treatment is ensured to reach the standard; the utility model discloses simple structure, convenient operation.
