Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 2, an exhaust gas deodorizing device 10 includes: a collecting pipeline 11, an alkaline washing tower 12, a fan 16, a biological deodorization device 17 and an active carbon adsorption device 18. The collecting line 11 serves to collect the exhaust gases. The caustic tower 12 is used to decompose pollutants in the exhaust gas for preliminary deodorization treatment. The fan 16 is used to draw the exhaust gas treated by the caustic tower 12. The biological deodorization device 17 is used for biologically deodorizing the exhaust gas treated by the alkaline tower 12. The activated carbon adsorption device 18 is used for performing activated carbon deodorization on the exhaust gas treated by the biological deodorization device 17.
As a specific embodiment, the caustic tower 12 is provided with a caustic tower air inlet 121 at the bottom and a caustic tower exhaust 122 at the top. The fan 16 is provided with a fan air inlet 161 and a fan air outlet 162. The collection line 11 communicates to the caustic tower inlet 121. The caustic tower exhaust 122 of the caustic tower 12 communicates through a first duct 14 to a fan inlet 161 of the fan 16. The biological deodorization device 17 and the activated carbon adsorption device 18 are integrally provided. The biological deodorization device 17 includes: a water washing device 171 and a biological filtration device 173. The top of the water washing device 171 is provided with a water washing air inlet 172. The fan outlet 162 of the fan 16 communicates through a second conduit 15 to the wash inlet 172. The bottom of the water washing unit 171 and the bottom of the bio-filter unit 173 communicate with each other through the first through-hole. The top of the biological filter 173 is communicated with the top of the activated carbon adsorption device 18 through the second through hole. A third pipeline for guiding the exhaust gas discharged from the second through hole to the bottom of the activated carbon adsorption device 18 is arranged in the activated carbon adsorption device 18. One end of the third pipeline is communicated to the second through hole, and the other end of the third pipeline is positioned at the bottom of the activated carbon adsorption device 18. The exhaust gas deodorizing device 10 further includes an exhaust pipe 22. The exhaust pipe 22 communicates with the activated carbon adsorption device 18. The exhaust gas treated by the activated carbon adsorption device 18 is discharged through the exhaust pipe 22.
Specifically, the collection piping 11 collects the exhaust gas from the sewage pumping station and discharges the exhaust gas into the bottom of the inside of the alkaline tower 12 through the alkaline tower gas inlet 121. The alkaline tower 12 is internally provided with an alkaline washing filler layer. The exhaust gas travels from bottom to top through the caustic wash packing layer and enters the fan inlet 161 of the fan 16 via the first conduit 14 through the caustic wash tower exhaust 122 located at the top of the caustic wash tower 12. The caustic tower 12 is sprayed with sodium hydroxide solution from top to bottom. The exhaust gas contacts the sprayed sodium hydroxide solution in a gas-liquid manner in the process of moving from bottom to top in the alkaline tower 12. In the contact process, the sodium hydroxide reacts with the pollutants to decompose the pollutants, so as to achieve the effect of primary removal. The gas-liquid directions are opposite, so that the reaction between the gas and the liquid can be more fully performed.
The exhaust gas from which the odor is preliminarily removed is discharged to the water washing unit 171 of the bio-deodorization unit 17 through the caustic tower exhaust port 122 via the first duct 14, the fan intake port 161, the second duct 15, and the water washing intake port 172, respectively. The exhaust gas discharged from the water washing inlet 172 located at the top of the water washing device 171 moves from the top down. The exhaust gas contacts the water sprayed from the top of the washing unit 171 while moving downward. At this time, the gas and liquid move in the same direction. In the contact process of the waste gas and the water, NaOH substances carried in the waste gas are washed by the water, so that the pH value of the waste gas is recovered to be normal, and the microbial degradation of pollutants is facilitated. And in the contact process of the waste gas and the water, the water removes particles and water-soluble substances in the waste gas, increases the humidity of the waste gas and is more beneficial to the microbial degradation of pollutants.
The exhaust gas treated by the water washing device 171 is discharged from the first through holes at the bottom of the water washing device 171 into the biofiltration device 173. The exhaust gas entering the biofiltration device 173 moves from bottom to top. A bio-filler layer is arranged in the bio-filter 173. The biological filler layer has the characteristics of being moist, porous and full of active microorganisms. The waste gas passes through the wet and porous biological filler layer filled with active microorganisms in the process of moving from bottom to top, and by utilizing the adsorption, absorption and degradation functions of microbial cells on malodorous substances, the microbial cells have the characteristics of small size, large specific surface area, strong adsorbability and various metabolic types, the malodorous substances are adsorbed and decomposed into simple inorganic substances such as CO2, H2O, H2SO4, HNO3 and the like, SO that the malodorous components such as NH3, H2S and the like are effectively removed.
The exhaust gas treated by the biofiltration device 173 is discharged into the top portion of the inside of the activated carbon adsorption device 18 through the second through-holes located at the top portion of the biofiltration device 173. The third pipe conveys the exhaust gas discharged from the second through-hole to the bottom of the activated carbon adsorption device 18. An active carbon filler layer is arranged in the active carbon adsorption device 18. The waste gas at the bottom of the activated carbon adsorption device 18 moves from bottom to top, and pollutants in the waste gas are further adsorbed when the waste gas passes through the activated carbon filler layer. And at the moment, the exhaust gas after the four-stage treatment reaches the emission standard, and then the exhaust gas is discharged through the exhaust funnel.
As a preferred embodiment, the exhaust gas deodorizing means 10 further comprises a first supplying means 13. The first supply device 13 is used to supply the caustic tower 12 with NaOH solution. The first supply device 13 includes a liquid storage tank 131 and a first liquid supply pump 132. The liquid storage tank 131 is used for containing NaOH solution. The top of the alkaline washing tower 12 is also provided with a liquid inlet 123. The reservoir 131 is connected to the first fluid supply pump 132 through a pipe. The first fluid supply pump 132 is connected to the fluid inlet port 123 via a line. The first feed pump 132 is used to deliver the NaOH solution to the inlet port 123 for injection into the caustic tower 12 supply.
As a preferred embodiment, the exhaust gas deodorizing device 10 includes two alkaline towers 12. The two caustic towers 12 are in communication with each other. The caustic tower exhaust port 121 of the upstream caustic tower 12 is communicated to the caustic tower 12 inlet of the downstream caustic tower 12 through a fourth conduit 23. The arrangement enables the exhaust gas with high odor concentration to fully react, thereby realizing high-efficiency deodorization.
As a preferred embodiment, the exhaust gas deodorizing means 10 includes two fans 16. The first pipe 14 is a tee pipe. One end of the first duct 14 is connected to an air outlet of the caustic tower 12 and the other two ends are connected to air blower air inlets 161 of the two air blowers 16, respectively. The top of the water washing device 171 is provided with two water washing air inlets 172. The two fan air outlets 162 are respectively communicated to the two water washing air inlets 172 through the second pipelines 15. The arrangement ensures that when the displacement of the waste gas is large, the waste gas can still be efficiently subjected to sufficient reaction, and efficient deodorization is realized.
As a preferred embodiment, the exhaust gas deodorizing means 10 further comprises a first water circulating means 20. The first water circulation device 20 is used for circulating water in the water washing device 171. Specifically, the first water circulation device 20 has a first water supply port 201 for supplying water to the water washing device 171 and a first return port 202 for collecting water in the water washing device 171.
