Description

Technical Field

[0001] The invention relates to the technical field of gas treatment, and in particular to a composite biological filtering device for treating gaseous pollutants. Background Art

[0002] Industrial odor refers to the unpleasant odor generated during the industrial production process. These odors may be released by the volatilization, combustion, chemical reaction and other processes of raw materials, intermediates or final products. Various malodorous gases will be produced during the treatment process of kitchen waste, the most important of which are ammonia and hydrogen sulfide.

[0003] At present, when kitchen waste is collected and processed, it is carried out in relatively sealed equipment. The kitchen waste will gradually ferment during the accumulation process, causing the temperature in the relatively sealed space to gradually increase. At present, biological-related filtering devices are mostly used for the treatment of malodorous waste gas. The higher temperature will make the organisms lose their activity, thereby greatly reducing the effect of treating malodorous waste gas. In addition, during the treatment of kitchen waste, the different stages of accumulation and fermentation and the state of tumbling garbage will cause the kitchen waste to produce malodorous waste gas at different speeds. If the speed of ammonia produced in the sealed space containing kitchen waste is accelerated, the ammonia concentration in the sealed space will increase in a short time. High-concentration ammonia is easily exploded by small sparks or static electricity in the sealed space, posing a great safety hazard. Therefore, a composite biological filtration device for the treatment of gaseous pollutants is proposed. Summary of the invention

[0032] Example, see Figures 1 to 9 A composite biological filtration device for treating gaseous pollutants comprises an inner filter tube 1 and an outer sleeve tube 2, the outer wall of the outer sleeve tube 2 located at the top is connected with a driving motor 4 through a liquid storage cavity ring 3, the driving motor 4 is connected to the outer sleeve tube 2 through a side drive component, the outer wall of the bottom end of the outer sleeve tube 2 is connected with a planetary component for expanding the heat dissipation space below the filter device, the planetary component is connected with a heat dissipation bucket 14 through a plurality of heat dissipation pipes 13, the heat dissipation bucket 14 is provided with an impeller 16 for stirring cooling water, and the liquid storage cavity ring 3 is provided with a hydraulic pump for pressing the cooling water flow;

[0033] Furthermore, the side drive assembly is composed of a driving gear 5 and a driven gear ring 6. The output end of the driving motor 4 is rotatably connected to the bottom end of the driving gear 5 through a driving shaft. The driving gear 5 and the driven gear ring 6 are meshed. The inner wall of the driven gear ring 6 is fixedly connected to the top of the outer sleeve 2. The outer wall of the outer sleeve 2 is rotatably connected to a mounting sealing ring 7. The kitchen waste treatment equipment is an existing device, which is provided with a ventilation hole as an existing structure. The mounting sealing ring 7 is installed with the ventilation hole of the equipment through a plurality of bolts. A through-pipe hole is opened on the mounting sealing ring 7.

The top of the spray hood 15 is rotatably connected to the bottom end of the impeller member 16.

[0034] It should be noted that: first, the filter device is fixedly installed at the exhaust hole position of the kitchen waste treatment equipment by installing the bolt structure on the sealing ring 7, then the sealing ring 7 is installed to fix the liquid storage chamber ring 3 through the folding branch pipe 11, and the liquid storage chamber ring 3 is fixed and limited to the inner filter tube 1 through the right-angle plate.

The rotation of the self-rotating gear ring 9 will drive the heat dissipation pipe 13 to rotate in the fixed ring at the edge of the inverted suction bucket 10.

[0035] At the same time, the hydraulic pump provided in the liquid storage cavity ring 3 is started to realize water pressure circulation. This is a prior art and will not be described in detail here. The internal cooling water is introduced into the rotating heat dissipation pipe 13 through the folding branch pipe 11 and the adapter cover 12, and the cooling water is sprayed out in a mist form through the spray hood 15. As the subsequent water flow continues to be introduced, it will impact the impeller member 16 in the heat dissipation bucket 14, causing the impeller member 16 to rotate and allow the water mist to escape and spray out to the periphery. The continuous rotation of the heat dissipation pipe 13 and the heat dissipation bucket 14 will drive the surrounding gas flow, which is convenient for the spraying of the escaped water mist to flow;

[0036] The above further benefits are: this can reduce the temperature of the space around the inverted suction hopper 10, so that the gas entering the inner filter tube 1 can maintain a lower temperature, avoiding damage to the microorganisms and filter elements in the entire filtration system, and ensuring the filtration effect of the filtration device;

[0037] The bottom end of the inner filter tube 1 is connected to an inverted suction hopper 10, and a temperature sensor and an ammonia detector for detecting temperature and ammonia concentration are fixedly connected to the inner side wall of the bottom end of the inverted suction hopper 10. A plurality of pressure relief holes for relieving excess ammonia are opened on the side wall of the inner filter tube 1 located at the bottom, and a sealing ring 18 is arranged above the pressure relief hole. The sealing ring 18 is connected to a biological filtration culture cylinder 19 through a plurality of backflow pipes 21. The bottom end of the biological filtration culture cylinder 19 is connected to a plurality of filtered gas return pipes 23 through a sealing plate 22, and the bottom end of the sealing plate 22 is connected to a suction assembly for extracting excess ammonia through a control motor 24;

[0038] Furthermore, the top of the liquid storage cavity ring 3 is fixedly connected to a porous PE final filter plate 29 through a right-angle plate, the bottom of the porous PE final filter plate 29 is fixedly connected to the top of the inner filter tube 1, the inner side wall of the bottom end of the inner filter tube 1 is fixedly connected to an activated carbon filter plate 17, the bottom of the inner filter tube 1 is fixedly connected to the top of the inverted suction hopper 10, the outer side wall of the inner filter tube 1 is rotatably connected to the inner side wall of the outer sleeve tube 2 through a sealing ring 18, the bottom of the sealed space formed by the inner filter tube 1 and the outer sleeve tube 2 is provided with weak acid water for dissolving excess ammonia, the top of the backflow pipe 21 is connected to the inside of the biological filtration culture cylinder 19 through an adapter ring 20, and the top of the biological filtration culture cylinder 19 is connected to the dry filter plate 28 is fixedly connected to the inner wall of the inner filter tube 1, the bottom end of the biological filtration culture cylinder 19 is fixedly connected to the inner wall of the inner filter tube 1 through a sealing plate 22, a plurality of air filter holes are opened on the sealing plate 22, and the air filter holes are communicated with the bottom of the biological filtration culture cylinder 19 through the air filter return pipe 23, the suction assembly includes an exhaust fan 27 arranged on the output shaft of the control motor 24, the control motor 24 is fixedly connected to the adjustment disk 25 through the output shaft, the adjustment disk 25 is fixedly connected to a plurality of gap fan-shaped plates 26 through a plurality of right-angle rods, the top end of the gap fan-shaped plates 26 is mutually attached to the bottom end of the sealing plate 22, and the biological filtration culture cylinder 19 is filled with a culture solution for culturing and filtering microorganisms;

[0039] It should be noted that: when the kitchen waste treatment equipment generates a lot of ammonia in a short period of time during the tumbling stage, it will be detected by the ammonia detector at the bottom of the inverted suction bucket 10, and then the signal transmission starts the control motor 24. After the control motor 24 is started, it will drive the adjustment disk 25 and the exhaust fan 27 to rotate through the output shaft. The rotation of the exhaust fan 27 will generate an inhalation airflow to inhale the ammonia at the inverted suction bucket 10 (the number of ammonia molecules is smaller than the number of air molecules. In the space of the treatment equipment, the ammonia will float above the air and accumulate at the top of the space);

[0040] The rotation of the regulating disk 25 will drive the gap sector plate 26 to rotate on the bottom end of the sealing plate 22 through a plurality of right-angle rods, so that the gap of the filter holes on the bottom end of the sealing plate 22 is opened, thereby controlling the amount of ammonia gas entering the biological filtration culture cylinder 19 through the filter gas return pipe 23. Then, a large amount of ammonia gas inhaled will pass through the pressure relief holes on the side wall of the inner filter tube 1 and enter the space at the bottom between the inner filter tube 1 and the outer sleeve tube 2. A large amount of ammonia gas will dissolve in the weak acid water (which can be a weak acid of carbonic acid) therein. As the amount of ammonia gas introduced increases, part of the ammonia liquid will be passed through the pressure relief holes on the side wall of the inner filter tube 1. The polluted gas is pressed into the biological filtration culture cylinder 19 through the backflow pipe 21, mixed with the culture solution in the biological filtration culture cylinder 19, and used as the culture supplement solution for filtering microorganisms. During the filtering process, the polluted gas passes through the activated carbon filter plate 17 to filter out tiny impurities in the polluted gas, and then passes through the composite microorganisms in the biological filtration culture cylinder 19 to treat and purify malodorous gases such as ammonia and hydrogen sulfide, and passes through the drying filter plate 28 to dry and filter the airflow, and finally passes through the porous PE final filter plate 29 for final filtration, and the purified airflow is discharged;

[0041] The above further benefits are: in this way, the high-concentration ammonia gas in the sealed space of the equipment can be quickly inhaled and dissolved, and the ammonia water formed by the dissolution process can be used as a culture supplement for filtering microorganisms in the biological filtration culture cylinder 19, thereby avoiding the accumulation of high-concentration ammonia gas that is difficult to filter quickly, which may cause safety hazards;

[0042] When the present invention is in use, the filter device is first fixedly installed at the exhaust hole position of the kitchen waste treatment equipment by installing the bolt structure on the sealing ring 7. Then, the sealing ring 7 is installed to fix the liquid storage chamber ring 3 through the folding branch pipe 11. The liquid storage chamber ring 3 is fixed and limited to the inner filter tube 1 through the right-angle plate. When the temperature rises due to the fermentation of garbage in the kitchen waste treatment equipment, the temperature sensor on the inner side wall of the bottom end of the inverted suction bucket 10 will sense it and transmit a signal to control the start of the drive motor 4. The start of the drive motor 4 will drive the drive gear 5 to rotate, thereby driving the meshing driven gear ring 6 to rotate. The driven gear ring 6 rotates and drives the outer sleeve tube 2 to rotate on the inner side wall of the liquid storage chamber ring 3. The rotation of the outer sleeve tube 2 drives the revolving gear ring 8 at the bottom to rotate. The rotation of the revolving gear ring 8 drives the meshing multiple self-rotating gear rings 9 to rotate synchronously. The rotation of the self-rotating gear ring 9 will drive the heat dissipation pipe 13 to rotate in the fixed ring at the edge of the inverted suction bucket 10.

[0043] At the same time, the hydraulic pump provided in the liquid storage cavity ring 3 is started, and the internal cooling water is passed into the rotating heat dissipation pipe 13 through the folding branch pipe 11 and the adapter cover 12, and the cooling water is sprayed out in the form of mist through the spray hood 15. As the subsequent water flow continues to be passed in, it will impact the impeller member 16 in the heat dissipation bucket 14, causing the impeller member 16 to rotate and allow the water mist to escape and spray out to the periphery. The continuous rotation of the heat dissipation pipe 13 and the heat dissipation bucket 14 will drive the surrounding gas flow, which is convenient for the spraying of the escaped water mist to flow, so that the temperature of the space around the inverted suction bucket 10 can be reduced, so that the gas entering the inner filter tube 1 can maintain a low temperature, avoid damage to the microorganisms and filter elements in the entire filtration system, and ensure the filtration effect of the filtration device;

[0044] When the kitchen waste treatment equipment generates a lot of ammonia in a short period of time during the tumbling stage during the process of treating the waste, it will be detected by the ammonia detector at the bottom of the inverted suction bucket 10, and then the signal transmission starts the control motor 24. After the control motor 24 is started, it will drive the adjustment disk 25 and the exhaust fan 27 to rotate through the output shaft. The rotation of the exhaust fan 27 will generate an inhalation airflow to inhale the ammonia at the inverted suction bucket 10 (the number of ammonia molecules is smaller than the number of air molecules. In the space of the treatment equipment, the ammonia will float above the air and accumulate at the top of the space);

[0045] The rotation of the regulating disk 25 will drive the gap fan-shaped plate 26 to rotate on the bottom end of the sealing plate 22 through a plurality of right-angle rods, so that the gap of the filter holes on the bottom end of the sealing plate 22 is opened, thereby controlling the amount of ammonia entering the biological filtration culture cylinder 19 through the filter gas return pipe 23, wherein the gap fan-shaped plate 26 rotates continuously, and the filter holes are continuously blocked at intervals, so that the filter holes are not always open, thereby preventing a large amount of ammonia from entering the biological filtration culture cylinder 19 through the filter holes. The large amount of ammonia inhaled will pass through the pressure relief holes on the side wall of the inner filter tube 1 and enter the space at the bottom between the inner filter tube 1 and the outer sleeve tube 2. A large amount of ammonia will dissolve in the weak acid water (which can be a weak acid of the carbonic acid class) therein. As the amount of ammonia introduced increases, part of the ammonia liquid will be pressed into the biological filtration culture cylinder 19 through the backflow pipe 21. In the filter culture cylinder 19, the culture liquid is mixed with the culture liquid in the biological filter culture cylinder 19 as a culture supplement liquid for the filtering microorganisms. During the filtering process, the polluted gas passes through the activated carbon filter plate 17 to filter out tiny impurities in the polluted gas, and then passes through the composite microorganisms in the biological filter culture cylinder 19 to treat and purify malodorous gases such as ammonia and hydrogen sulfide, and passes through the drying filter plate 28 to dry and filter the airflow, and finally passes through the porous PE final filter plate 29 for the final filtration, and the purified airflow is discharged, so that the high-concentration ammonia in the sealed space of the equipment can be quickly inhaled and dissolved, and the ammonia water formed by the dissolution treatment can be used as the culture supplement liquid for the filtering microorganisms in the biological filter culture cylinder 19, so as to avoid the accumulation of high-concentration ammonia that is difficult to filter quickly, causing safety hazards.
