In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
As shown in fig. 1, the wastewater treatment polluted gas purification system of the present disclosure includes a polluted gas collection device and a polluted gas purification device.
The contaminated gas collecting apparatus includes a collecting mechanism, a collecting duct 3, and at least two adsorption towers 4. The collecting mechanism comprises a collecting cover 1 and an exhaust fan 2, the exhaust fan 2 is installed in the collecting cover 1, and the exhaust fan 2 can be used for pumping the polluted gas into the collecting cover 1. In specific implementation, in order to improve the efficiency of collecting the polluted gas, the collecting cover 1 may have a horn-shaped structure, and the exhaust fan 2 is located at one end of the collecting cover 1 with a smaller caliber.
One end of the collecting pipeline 3 is connected with the collecting cover 1, the other end of the collecting pipeline 3 is communicated with the adsorption towers 4, and the adsorption towers 4 are arranged in parallel. The adsorption tower 4 is internally provided with adsorption filler. The adsorbent packing within adsorption column 4 is typically a type of packing that is desorbable, for example, ceramic particulate packing. The adsorption filler can adsorb the polluted gas and desorb ammonia gas and hydrogen sulfide gas in the adsorbed polluted gas.
The polluted gas purification device comprises a suction mechanism 5, a suction pipeline 6 and a purification mechanism. The suction mechanism 5 is connected with each adsorption tower 4 through a suction pipeline 6, and the suction mechanism 5 can be used for extracting the polluted gas adsorbed by the adsorption towers 4. The suction means 5 may be, for example, an air compressor. The purification mechanism comprises a purification pipeline 7 and a purification box 8. The two ends of the purifying pipeline 7 are respectively connected with the suction mechanism 5 and the purifying box 8. A purifying agent 80 for purifying ammonia gas and hydrogen sulfide is provided in the purifying tank 8. The scavenger 80 may be a solid scavenger and/or a liquid scavenger.
The working process of the wastewater treatment and pollution gas purification system is as follows:
the extraction fan 2 is from collecting cover 1 suction collection pipeline 3 with the gaseous pollutants that produces among the waste water treatment process, and collection pipeline 3 is leading-in adsorption tower 4 with gaseous pollutants, and the adsorption filler in adsorption tower 4 adsorbs gaseous pollutants. Then, the contaminated gas adsorbed by the adsorption tower 4 enters the suction duct 6 and enters the purge tank 8 through the purge duct 7 by the suction action of the suction mechanism 5. The polluted gas reacts with the purifying agent 80 in the purifying tank 8, thereby realizing the purification of the polluted gas.
The waste water treatment polluted gas purification system disclosed by the invention improves the purification efficiency of the polluted gas in the waste water treatment polluted gas purification system by a mode of firstly adsorbing the polluted gas and then desorbing the polluted gas, and avoids the escape of untreated polluted gas.
The waste water treatment polluted gas purification system can collect and purify polluted gas generated in the waste water treatment process, is easy to realize, and can effectively purify the polluted gas generated in the cigarette production waste water treatment process.
In one embodiment of the wastewater treatment contaminated gas purification system of the present disclosure, the collection pipe 3 is connected to the bottom of each adsorption tower 4, and the suction pipe 6 is connected to the top of each adsorption tower 4. Like this, the contaminated gas gets into adsorption tower 4 from the bottom of adsorption tower 4 to leave from the top of adsorption tower 4, effectively guaranteed the abundant contact of contaminated gas with the adsorption filler in the adsorption tower 4.
In an embodiment of the wastewater treatment and pollution gas purification system of the present disclosure, a plurality of control valves 30 are further disposed in the collection pipe 3, and are in one-to-one correspondence with the adsorption towers 4. The control valve 30 may be used to control the intake air flow rate on the intake side of each adsorption tower 4. The control valve 30 may be, for example, a solenoid valve. By controlling the valve 30, the amount of the contaminated gas entering each adsorption tower 4 can be controlled, thereby more effectively controlling the adsorption amount of the adsorption tower 4. In specific implementation, the control valves 30 corresponding to the adsorption towers 4 can be independently controlled.
Further, the total amount of the contaminated gas entering the adsorption tower 4 is smaller than the total amount of the contaminated gas entering the collecting side of the collecting hood 1. This arrangement facilitates the formation of negative pressure between the collection hood 1 and the adsorption tower 4 under the suction action of the suction mechanism 5 on the adsorption tower 4, thereby improving the collection efficiency of the collection hood 1.
Further, the total amount of contaminated gas entering the adsorption tower 4 is at least 90% of the total amount of contaminated gas entering the collection side of the collection hood 1.
Further, the adsorption towers 4 have a cylindrical structure, and the central axes of the adsorption towers 4 are parallel and not collinear. The central axes of the adsorption towers 4 are parallel and not collinear, so that the distances between the adsorption towers 4 and the pumping mechanism 5 are different, and the pumping efficiency of the pumping mechanism 5 is effectively improved.
Further, each adsorption tower 4 is gradually separated from the suction mechanism 5 from the top to the bottom.
In one embodiment of the wastewater treatment contaminated gas purification system of the present disclosure, the purification mechanism further comprises an exhaust conduit 9. One end of the exhaust pipeline 9 is communicated with the purification box 8, the other end of the exhaust pipeline 9 is communicated with the atmosphere, and a rainproof cover 91 is arranged at one end of the exhaust pipeline 9 communicated with the atmosphere. The exhaust duct 9 can discharge the gas purified in the purification tank 8. Rain-proof cover 91 can effectively avoid rainwater and debris to get into purifying box 8.
Further, an exhaust fan 92 is disposed in the exhaust duct 9. The provision of the exhaust fan 92 facilitates more rapid discharge of the gas purified in the purification tank 8 out of the purification tank 8.
Further, the scavenger 80 is an aqueous solution including sodium hydroxide and sodium hypochlorite. One end of the purifying pipe 7 connected with the purifying tank 8 is positioned below the liquid level of the purifying agent 80.
The sodium hydroxide in the purifying agent 80 is strong alkali, and can quickly react with the hydrogen sulfide gas, and the stability of the sodium hypochlorite in the purifying agent 80 is ensured. The chemical formula for the reaction of scavenger 80 with hydrogen sulfide is as follows:
2NaOH+H2S＝2H2O+Na2S；
Na2S+4NaClO＝Na2SO4+4NaCl。
ammonia gas in the polluted gas may be dissolved in the depurative 80.
