Description

Technical Field

[0001] The invention belongs to the technical field of biological deodorization, and specifically refers to a biological deodorization device for a waste gas deodorizer. Background Art

[0002] The working principle of the biological deodorization device is based on the metabolism of microorganisms. When the waste gas passes through the biological filter layer in the device, the microorganisms will use the organic matter in the waste gas as a carbon source and energy source to grow and reproduce. In this process, the microorganisms will decompose and transform the malodorous substances in the waste gas, such as hydrogen sulfide, ammonia, methyl mercaptan, etc., into carbon dioxide, water and other harmless substances.

[0003] The existing biological deodorization devices have the following problems: When the existing biological deodorization device decomposes and treats the waste gas, the waste gas circulates inside the biological filter layer for a long time, which is easy to affect the humidity of the biological filter layer. If the humidity of the biological filter layer is too high, it will affect the mass transfer efficiency of the gas and cause a local anaerobic environment, affecting the deodorization efficiency of the microorganisms. If the humidity of the biological filter layer is too low, it will cause the filler to dry out and the biological activity in the wet bed to decrease, thereby affecting the deodorization effect. Therefore, it cannot meet the existing use requirements of the biological deodorization device. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a biological deodorization device for a waste gas deodorizer that can reduce the probability of moisture in the waste gas affecting the humidity inside the biological filter layer, and ensure that the microorganisms in the biological filter layer decompose the organic matter in the waste gas at a relatively stable humidity.

[0005] The technical scheme adopted in this scheme is as follows: This scheme proposes a biological deodorization device for a waste gas deodorizer, including a base, a filter frame, a sealing box, a concentration-type speed-up mechanism and a scheduling-type negative suction mechanism. The filter frame is arranged on the upper wall of the base, and multiple groups of the sealing boxes are arranged on the inner wall of the filter frame. The concentration-type speed-up mechanism is arranged on the filter frame, and the scheduling-type negative suction mechanism is arranged on the sealing box. The concentration-type speed-up mechanism includes a dust removal mechanism, a diversion mechanism and a decomposition mechanism. The dust removal mechanism is arranged on the upper wall of the filter frame, the diversion mechanism is arranged on one side of the dust removal mechanism, and the decomposition mechanism is arranged inside the sealing box. The scheduling-type negative suction mechanism includes a heating mechanism, a mist suction mechanism and an atomization mechanism. The heating mechanism is arranged on the side of the dust removal mechanism away from the diversion mechanism, the mist suction mechanism is arranged on the side wall of the sealing box, and the atomization mechanism is arranged at one end of the filter frame close to the base.

[0006] As a further preferred embodiment of the present invention, the impurity removal mechanism includes an air intake platform, an air intake cylinder and a filter cotton layer, the air intake platform is arranged on the upper wall of the filter frame, the air intake cylinder is arranged on the side of the air intake platform close to the sealed box, and the filter cotton layer is arranged inside the air intake cylinder; the diversion mechanism includes a diversion frame, a one-way air intake valve, a diversion pipe and a one-way exhaust valve, the diversion frame is arranged on the upper wall of the filter frame at one end away from the air intake platform, the one-way air intake valve is connected and arranged on the side of the sealed box close to the diversion frame, the diversion pipe passes through the diversion frame and is connected and arranged between the one-way air intake valve and the air intake cylinder, and multiple groups of the one-way exhaust valves pass through the filter frame and are connected in sequence from top to bottom and are arranged on the side of the sealed box away from the one-way air intake valve; the decomposition mechanism includes a fixed plate, a biological filter layer and a humidity sensor, the fixed plate is symmetrically arranged on the top and bottom walls of the sealed box, the biological filter layer is arranged between the fixed plates, the humidity sensor is arranged on the upper wall of the sealed box, and the detection end of the humidity sensor passes through the sealed box and is arranged inside the biological filter layer.

[0007] When in use, waste gas enters the air intake cylinder, and the waste gas entering the air intake cylinder flows into the diversion pipe under the filtration of the filter cotton layer. The waste gas inside the diversion pipe flows into the sealed box through the one-way air intake valve, and the waste gas flowing into the sealed box is filtered by the biological filter layer and discharged from the one-way exhaust valve.

[0008] Preferably, the heating mechanism includes an air intake copper tube, an exhaust gas joint and a heating coil. The air intake copper tube passes through the air intake platform and is connected to a side of the air intake cylinder away from the shunt tube. The exhaust gas joint is connected to a side of the air intake copper tube away from the air intake cylinder, and the heating coil is arranged on the outside of the air intake copper tube; the mist suction mechanism includes a mist suction plate, a mist pipe and an electric one-way valve. Multiple groups of the mist suction plates are arranged on the inner wall of the filter frame, the mist pipe is arranged on the side wall of the mist suction plate between the sealing boxes, and multiple groups of the electric one-way valves are connected between the mist pipe and the sealing box; the atomization mechanism includes a mist box, an annular tube and an atomization motor. The mist box is arranged at one end of the filter frame close to the base, the annular tube is connected between the mist pipe and the mist box, the atomization motor is arranged on the bottom wall of the mist box, and the atomization end of the atomization motor passes through the inside of the mist box.

[0009] When in use, the heating coil heats the air intake copper tube, and the heating temperature of the heating coil on the air intake copper tube is controlled. After the temperature of the air intake copper tube rises, the exhaust gas passing through it is heated. The exhaust gas with increased temperature is adsorbed by the filter cotton layer and flows into the diversion pipe. The appropriate temperature is conducive to the growth of microbial flora inside the biological filter layer.

[0010] Specifically, a controller is provided on the upper wall of the air intake cylinder.

[0011] Wherein, the controller is electrically connected to the humidity sensor, the heating coil and the atomizing motor respectively.

[0012] Preferably, the model of the controller is SYC89C52RC-401.

[0013] Furthermore, the model of the humidity sensor is M31 / BS-8906.

[0014] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a combination of an exhaust gas drying structure and a negative pressure mist suction structure. Through the concentration-type speed-up mechanism and the scheduling-type negative suction mechanism, the moisture contained in the exhaust gas can be eliminated under the coordinated use of the impurity removal mechanism, the diversion mechanism, the decomposition mechanism, the heating mechanism, the mist suction mechanism and the atomization mechanism, thereby reducing the probability of the exhaust gas increasing the humidity inside the biological filter layer after passing through the biological filter layer, and ensuring the reproduction and growth of the microbial flora inside the biological filter layer and the decomposition efficiency of the organic matter in the exhaust gas. When the dry exhaust gas flows through the biological filter layer, it will carry the moisture inside the biological filter layer and thus reduce the humidity inside the biological filter layer. At this time, the high-speed flow of exhaust gas inside the sealed box will generate a relative negative pressure inside it. The sealed box absorbs the mist inside the mist pipe through the electric one-way valve, and the mist enters the biological filter layer inside the sealed box, thereby maintaining the relative humidity of the biological filter layer, thereby improving the biological filter layer's purification efficiency for exhaust gas to a certain extent.

[0022] The heating mechanism 19 includes an air intake copper tube 20, an exhaust gas joint 21 and a heating coil 22. The air intake copper tube 20 passes through the air intake platform 6 and is connected to the side of the air intake cylinder 7 away from the shunt pipe 12. The exhaust gas joint 21 is connected to the side of the air intake copper tube 20 away from the air intake cylinder 7. The heating coil 22 is arranged on the outside of the air intake copper tube 20. The mist suction mechanism 23 includes a mist suction plate 24, a mist pipe 25 and an electric one-way valve 26. Multiple groups of the mist suction plates 24 are arranged on the inner wall of the filter frame 2.

[0023] A controller 31 is disposed on the upper wall of the air intake cylinder 7 .

[0024] The controller 31 is electrically connected to the humidity sensor 17 , the heating coil 22 , and the atomizing motor 30 , respectively.

[0025] The model of the controller 31 is SYC89C52RC-401.

[0026] The model of the humidity sensor 17 is M31 / BS-8906.

[0027] When in use, the exhaust gas discharge pipe is connected to the exhaust gas joint 21, the controller 31 controls the heating coil 22 to start, the heating coil 22 heats the intake copper tube 20, and controls the heating temperature of the intake copper tube 20 by the heating coil 22. After the temperature of the intake copper tube 20 is increased, the exhaust gas passing through the inside thereof is heated, and the exhaust gas with increased temperature enters the inside of the intake cylinder 7; The harmful concentration in the exhaust gas inside the air intake cylinder 7 is relatively high. When the exhaust gas temperature rises, the moisture in the exhaust gas evaporates. The filter cotton layer 8 inside the air intake cylinder 7 adsorbs and filters the moisture and impurities in the heated exhaust gas. The exhaust gas filtered by the filter cotton layer 8 flows into the shunt pipe 12 respectively. At this time, the concentration of harmful substances in the exhaust gas inside the shunt pipe 12 is reduced, which is convenient for increasing the flow rate of the exhaust gas, accelerating the exhaust gas circulation inside the sealed box 3, and increasing the processing rate of the biological filter layer 16 for the exhaust gas. The exhaust gas inside the shunt pipe 12 flows into the sealed box 3 through the one-way air intake valve 11. The exhaust gas flowing into the sealed box 3 is filtered by the biological filter layer 16 and then discharged from the one-way exhaust valve 13. The suitable temperature of the exhaust gas is conducive to the growth of microbial flora inside the biological filter layer 16. The greater the waste gas flow rate and the faster the flow rate, the stronger the impact and suction effect on the biological filter layer 16, thereby increasing the negative pressure generated inside the sealed box 3. When the dry waste gas passes through the biological filter layer 16, the humidity inside the biological filter layer 16 will be reduced, affecting the growth and reproduction of microorganisms inside the biological filter layer 16 and the decomposition efficiency of organic matter. At this time, the controller 31 controls the electric one-way valve 26 to start, and the mist pipe 25 is connected to the sealed box 3. The opening of the electric one-way valve 26 is adjusted to control the flow rate of the water mist. The controller 31 controls the atomizing motor 30 to start. The atomizing motor 30 atomizes the moisture inside the mist box 28 through the atomizing end. The water mist generated by the atomization flows into the corresponding mist pipe 25 through the annular tube 29 and enters the sealed box 3. Under the action of the negative pressure generated internally, the mist in the mist pipe 25 flows into the biological filter layer 16 to maintain the humidity of the biological filter layer 16. The controller 31 controls the humidity sensor 17 to start, and the humidity sensor 17 monitors the humidity inside the biological filter layer 16 through the detection end. When the moisture carried by the exhaust gas flowing through the biological filter layer 16 is greater than the moisture supplied to the biological filter layer 16 by the electric one-way valve 26, the controller 31 controls the opening of the electric one-way valve 26 to increase the flow rate of the mist through the electric one-way valve 26, thereby ensuring that the humidity inside the biological filter layer 16 is not affected by the circulation of the heated exhaust gas, thereby completing the rapid purification of the exhaust gas while avoiding changes in the humidity inside the biological filter layer 16; the above operation can be repeated the next time it is used.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto.
