Description

Technical Field

[0001] The invention relates to a wet dust collector, in particular to a high-efficiency wet cyclone dust collector with dust reduction and carbon fixation functions, belonging to the technical field of wet dust removal. Background Art

[0002] With the rapid development of industrialization today, environmental pollution problems are becoming increasingly severe, especially the dust and carbon dioxide emissions generated in the industrial production process, which have become an important source of air pollution. Although traditional dust removal technology can effectively remove most of the dust, it has obvious deficiencies in reducing carbon dioxide emissions. Taking the wet cyclone dust collector as an example, the wet cyclone dust collector, as a relatively common dust removal equipment, usually includes an axial flow fan, a cyclone dust removal device and a dehydration device. After the wet cyclone dust collector inhales dust-laden air through the dust hood and the suction air tube pipeline, the fine dust in the dust-laden air is fully moistened under the action of water mist, and collides and condenses with each other to form a dust-water mixture. The dust-water mixture is intercepted and formed into dust mud when passing through the cyclone dust removal and dehydration device. Under the impetus of the wind flow, it enters the diffusion water collection section for collection and is discharged from the sewage pipeline. The purified clean air is emptied to achieve dust removal and purification of the dust-laden airflow. This traditional wet cyclone dust collector can remove dust from the airflow, but it cannot capture and fix greenhouse gases such as carbon dioxide in the airflow. Summary of the invention

It has the following specific advantages:

[0026] 1. After spraying the microbial culture solution with dust reduction and carbon fixation function, the microorganisms can absorb particulate matter and reduce the concentration of particulate matter in the dust-laden gas by means of special adsorption sites on their surface. At the same time, they can decompose and transform carbon dioxide to achieve dust reduction and carbon fixation. This process can reduce the accumulation of microorganisms and particulate matter in the dust collector, maintain the cleanliness of the system, and enhance the dust removal capacity. When the ultrasonic vibrator in the water purification chamber is working, a large number of bubbles are generated. The impact force generated by the expansion and rupture of the bubbles can effectively separate dust particles, especially fine particles. The clean water after ultrasonic treatment and the microbial culture solution are fully mixed in the dust collector, which can further improve the dust reduction and carbon fixation effect and dust removal efficiency.

[0027] 2. The heat generated by the growth and fermentation of microorganisms can be introduced into the dust removal chamber through the heat exchanger, which can preheat the dust-containing gas entering the dust removal chamber, improve the dust removal efficiency and reduce external energy consumption. At the same time, water resources are recycled through the reflux chamber and the return mist pipe. The reflux water mist moistens the dust-containing gas at the air inlet pipe, which can reduce waste and improve the dust removal effect.

[0028] 3. The shuttle-shaped structure of the axial flow fan motor housing can reduce flow resistance and increase flow rate during drainage. It has a self-cleaning function, strong adaptability and energy efficiency. The axial flow fan motor housing cooperates with the cyclone separator to allow the heavier dust-water mixture to enter the sewage chamber; the setting of the return port, return chamber and return mist pipe can help improve the particle capture ability of the wet cyclone dust collector.

[0041] A microorganism culture tank 8 is provided in the microorganism culture room. Figure 5 As shown, the microorganism culture tank 8 includes a liquid inlet 89, a liquid discharge port 810, a stirring mechanism and a cleaning mechanism;

[0042] The liquid inlet 89 is used to input microbial liquid and nutrient solution, and can be connected to the source of microbial liquid and nutrient solution through a pipeline;

[0043] The discharge port 810 is used to output the microorganism culture solution, and the discharge port 810 is connected to the microorganism culture solution inlet pipe through a microorganism culture solution delivery pump;

[0044] The stirring mechanism for stirring is arranged inside the microorganism culture tank 8, including a stirring main shaft installed at the central axis position of the microorganism culture tank 8, one end of the stirring main shaft extends to the outside of the microorganism culture tank 8 and is connected to the stirring motor 81 in transmission, and the stirring main shaft is provided with a stirring paddle 84 connected to it in transmission. In order to achieve a better stirring effect, the stirring paddle 84 may include a circumferential stirring paddle arranged along the axial direction of the stirring main shaft with the rotating central axis (the rotation direction of the circumferential stirring paddle is the same as the rotation direction of the stirring main shaft) and a radial stirring paddle arranged along the radial direction of the stirring main shaft with the rotating central axis (the rotation direction of the radial stirring paddle is perpendicular to the rotation direction of the stirring main shaft). The stirring motor 81 can realize the rotation of the circumferential stirring paddle and the radial stirring paddle by driving the stirring main shaft to rotate, thereby realizing stirring in different directions;

[0045] The cleaning mechanism for cleaning includes a cleaning brush 82 and a water outlet pipe 83; the cleaning brush 82 is installed inside the microorganism culture tank 8 through a cleaning brush holder, and the cleaning brush 82 is close to the inner wall of the microorganism culture tank 8. The cleaning brush holder is provided with a brush holder rotation drive mechanism that can control the cleaning brush holder to rotate along the circumferential direction of the microorganism culture tank 8 and a brush holder translation drive mechanism that can control the cleaning brush holder to move along the axial direction of the microorganism culture tank 8. The brush holder rotation drive mechanism can be a rotation drive structure including a separately arranged brush holder rotation drive motor, or a brush holder rotation drive motor that does not interfere with the stirring paddle 84. In the case of a rotary drive structure connected to the stirring motor 81, the brush holder translational drive mechanism may be a spiral translational drive structure including a screw and a nut, or may be other translational drive structures such as a telescopic cylinder structure. A high-pressure washing nozzle is provided inside the cleaning brush 82. The high-pressure washing nozzle is connected to a cleaning liquid tank 812 containing cleaning liquid through a pipeline and a washing pump. The cleaning liquid tank 812 may be positioned around the microorganism culture tank 8. The water outlet pipe 83 is connected to the microorganism culture tank 8, and is used to discharge the cleaning liquid in the microorganism culture tank 8 after cleaning.

[0046] An ultrasonic vibrator 91 can be arranged in the water purification chamber 9. The ultrasonic vibrator 91 can cause the water in the water purification tank 9 to produce a large number of tiny bubbles. These bubbles will continue to expand and burst during the vibration process, thereby forming a strong impact force. The tiny airflow and pressure generated by the bursting of the bubbles can effectively separate dust particles, especially fine particles; the water purification chamber 9 is provided with a clean water inlet and a clean water outlet. The clean water inlet can be connected to the clean water source through a pipeline, and the clean water outlet is connected to the clean water inlet pipe through a clean water delivery pump.

[0047] A sewage discharge port is provided in the sewage chamber 10, and the sewage discharge port can be connected to a subsequent sewage treatment unit through a pipeline.

[0048] When the high-efficiency wet cyclone dust collector with dust reduction and carbon fixation function is used for dust removal, the microbial liquid and nutrient solution can be firstly input into the microbial culture tank 8 through the liquid inlet 89. The input microbial liquid can be a liquid of Bacillus halodurans, a liquid of Spirulina, a liquid of Nitrosomonas, a liquid of Nitrobacter, a liquid of Methylococcus spherical capsulatus bacterial liquid, Thiobacillus bacterial liquid and other water-soluble microbial bacterial liquids that can fix carbon, start the stirring motor 81 to fully stir the microbial bacterial liquid and nutrient solution in the microbial culture tank 8, so that the microorganisms are fully in contact with the nutrient solution to grow and ferment. After the microorganisms are fully fermented and mature, start the axial flow fan 4, ultrasonic vibrator 91, clean water delivery pump, and microbial culture liquid delivery pump at the same time. The dust-containing gas enters the dust removal chamber through the air inlet pipe 11 under the negative pressure of the axial flow fan 4. At the same time, the clean water and the fermented mature microorganisms are sprayed out through the atomizing nozzle of the double-material spray ring 3 and are fully mixed. During this period, the fine dust in the dust-containing gas is fully moistened, and collides and condenses with each other to form a dust-water mixture, and the fermented mature microorganisms can convert carbon dioxide in the dust-containing gas into The dust and water mixture is converted into chemical products (such as alcohol, organic acid, etc.), and collide and condense to mix into the dust-water mixture. The gas in the dust removal chamber forms a swirl under the guiding action of the guide blades of the axial flow fan motor housing 5, and enters the swirl separator 6 through the induced draft tube of the swirl separator 6. When the swirl gas entering the swirl separator 6 passes through the annular separation chamber 61, the center of the overall circular contour surface formed by the protruding dehydration grid 64 is eccentrically located below the center of the annular separation chamber 61. Therefore, under the blocking action of the dehydration grid 64, the dust-water mixture with a larger weight can enter the sewage chamber 10 through the sewage discharge port 63 at the bottom of the annular separation chamber 61 for temporary storage, and the dust-removed and purified gas can be discharged through the air outlet 12, so that the dust in the dust-containing gas is removed and the greenhouse gases such as carbon dioxide in the dust-containing gas are captured and fixed. The microbial culture liquid and nutrient solution can be continuously input into the microbial culture tank 8 at a set speed and flow rate to achieve continuous operation of continuous cultivation and supply of microorganisms.

[0049] After the dust removal and carbon fixation operation is completed, the microorganism culture tank 8 can be emptied through the outlet pipe 83 first, and then the cleaning mechanism is started, and the cleaning liquid is sprayed out by controlling the high-pressure washing nozzle of the cleaning brush 82, and the cleaning brush frame is controlled to rotate along the circumferential direction of the microorganism culture tank 8 and move along the axial direction of the microorganism culture tank 8 to achieve washing of the inner cavity wall of the microorganism culture tank 8 to remove dirt and sediments. After washing, the microorganism culture tank 8 can be emptied through the outlet pipe 83. At the same time, the sewage in the sewage chamber 10 can enter the subsequent process for treatment.

[0050] In order to achieve a better dust removal effect, as a further improvement of the present invention, the cyclone separator 6 also includes a reflux port 62 located at the top of the cyclone separator 6, and a reflux chamber 7 connected to the air outlet pipe 12 is provided at the position corresponding to the reflux port 62 inside or outside the dust removal chamber, and the reflux chamber 7 is connected to the reflux port 62, and the reflux chamber 7 is connected to the return mist pipe 2 extending to the front of the dust removal chamber. When the cyclone gas entering the cyclone separator 6 passes through the annular separation chamber 61, a small part of the gas-liquid mixture can enter the reflux chamber 7 through the reflux port 62, and the gas entering the reflux chamber 7 through the air outlet pipe 12 can push the gas-liquid mixture to flow back to the inner front of the dust removal chamber through the return mist pipe 2. The gas-liquid mixture contains a certain amount of moisture, which helps the fine particles in the air to absorb moisture and form larger particles, thereby improving the particle capture capacity of the wet cyclone dust collector. In order to further improve the return mist effect, the inner diameter of the return mist pipe 2 gradually decreases from back to front, thereby increasing the return mist pressure and improving the return mist effect.

[0051] In order to achieve better cleaning effect, as a further improvement scheme of the present invention, the cleaning mechanism also includes a sterile air pipe 85 and a steam sterilization pipe 87 which are connected to the microbial culture tank 8. After washing is completed and the microbial culture tank 8 is emptied through the outlet pipe 83, high-temperature steam can be injected into the microbial culture tank 8 through the steam sterilization pipe 87 for sterilization, and then sterile air can be injected through the sterile air pipe 85 to avoid residual microorganisms.

[0052] In order to achieve purposeful control of the growth and fermentation reaction of microorganisms and thus achieve better carbon fixation effect, as a further improvement scheme of the present invention, a pH control port 86 is also provided on the microbial culture tank 8. During the microbial culture process, pH regulating liquid can be input through the pH control port 86 to adjust the pH value of the microbial bacterial liquid and the nutrient solution, thereby achieving purposeful control of the growth and fermentation reaction of microorganisms.

[0053] In order to make full use of the heat of the fermentation reaction, as a further improvement of the present invention, a closed-loop heat exchanger 811 is also provided on the microbial culture tank 8 and the inner front of the dust removal chamber (the closed-loop heat exchanger is a prior art and will not be described in detail). The heat generated during the microbial culture process can be used to heat the gas entering the dust removal chamber through the air inlet pipe 11 through the heat exchanger 811, which can improve the adhesion of dust and enhance the dust removal efficiency.

[0054] In order to facilitate the intuitive observation of the culture effect of microorganisms and realize automation, as a further improvement scheme of the present invention, the microorganism culture chamber is also provided with a control screen 88 and a controller. The operator can control the injection amount of microorganism liquid and nutrient solution, the injection amount of pH adjusting solution and other microbial culture conditions through the control screen 88, and can also control the stirring mechanism and the cleaning mechanism through the control screen 88.

[0055] This high-efficiency wet cyclone dust collector with dust reduction and carbon fixation functions integrates microbial dust removal technology on the basis of existing wet dust removal technology through the mutual cooperation of various parts. It can not only reduce energy consumption and improve dust treatment effects, but also capture and fix greenhouse gases such as carbon dioxide, thereby reducing air pollution, improving the comprehensive energy utilization efficiency of the dust removal system, and providing a more environmentally friendly and energy-saving solution for industrial production processes.
