Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet dust collector technology, specifically to a negative pressure type high-efficiency microbubble wet dust collector. Background Technology
[0002] A wet scrubber is a device that uses close contact between dust-laden gas and liquid to capture particles, enlarge them, or retain them in a fixed container, thereby achieving the effect of separating water and dust. The most important component of a wet scrubber is the liquid atomization spray system.
[0003] Among them, the negative pressure type high-efficiency microbubble wet dust collector mainly relies on water and microbubble technology. It uses a negative pressure system to draw dust-laden gas into the dust collector. Inside the equipment, a large number of microbubbles are generated through a gas-water mixing device. These bubbles can effectively combine with fine particulate matter in the air and can adsorb dust particles in the air. Although the existing negative pressure type high-efficiency microbubble wet dust collector can capture a certain amount of particulate matter, its ability to remove volatile organic compounds in the gaseous state is limited. It lacks the ability to treat particulate matter, oil mist and other components contained in the gas. The poor adhesion of these organic components leads to unsatisfactory dust removal effect. Utility Model Content
[0004] The purpose of this invention is to provide a negative pressure type high-efficiency microbubble wet dust collector to overcome the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A negative pressure type high-efficiency microbubble wet dust collector includes an adsorption box. A first pipe is connected to one side of the adsorption box, and a filter assembly is installed at one end of the first pipe. A second pipe is connected to the other side of the adsorption box, and a CO furnace is connected at one end of the second pipe. An air inlet pipe is installed on one side of the filter assembly, and an exhaust pipe is installed on one side of the CO furnace. A third pipe is connected to the top of the exhaust pipe, and an electrically controlled valve is installed on the third pipe. One end of the third pipe is connected to the top of the adsorption box. The filter assembly includes a filter tank located at the bottom of the first pipe. A partition is fixedly connected to the inner wall of the filter tank. A water supply pipe is connected to the top of the filter tank, and a spray pipe is connected at one end of the water supply pipe. Several atomizing nozzles are provided at the bottom of the spray pipe. A filter plate is fixedly installed on the inner wall of the filter tank. A drain pipe is connected to one side of the filter tank. A microbubble generator is installed at the top of the filter tank, and the water outlet of the microbubble generator is connected to the top of the spray pipe via a pipe.
[0007] Preferably, a motor is fixedly connected to the bottom of the adsorption box, a lead screw is fixedly connected to the output end of the motor, and a lifting plate is screwed onto the lead screw.
[0008] Preferably, three placement mesh cylinders are bolted to the top of the lifting plate, and activated carbon is added inside the placement mesh cylinders.
[0009] Preferably, the top of the adsorption box is equipped with a rotatable sealing door, and a support rod is inserted into one side of the lifting plate.
[0010] Preferably, a water pump is provided on one side of the filter tank, one end of the water pump is connected to a water tank through a water pumping pipe, and the drain end of the water pump is connected to one end of a water supply pipe.
[0011] Preferably, mounting blocks are fixedly connected to both sides of the inner wall of the water tank, and a filter screen is installed inside the mounting block. A water filling pipe is connected to one side of the water tank.
[0012] In the above technical solution, the negative pressure type high-efficiency microbubble wet dust collector provided by this utility model has the following beneficial effects:
[0013] 1. Exhaust gas enters the filter tank through the inlet pipe. The baffle divides the interior of the filter tank into a spray chamber and a filtration chamber. Water is supplied to the spray pipe through the water supply pipe. The water is sprayed out through the atomizing nozzle at the bottom of the spray pipe. The sprayed water forms a water mist to perform preliminary filtration of odors and particulate matter in the exhaust gas in the spray chamber. At the same time, the outlet of the microbubble generator is connected to the spray pipe. When the microbubble water is sprayed out through the spray pipe, the microbubbles carry the water flow and are evenly distributed in the spray chamber, which enhances the contact between the bubbles and the liquid and improves the treatment effect.
[0014] Second, the exhaust gas then enters the filtration chamber through the ventilation holes in the middle of the partition. The two filter plates filter the water vapor and oil mist in the exhaust gas, pre-treating the exhaust gas before activated carbon adsorption to prevent particulate matter, oil mist and other components in the exhaust gas from affecting the adsorption effect of activated carbon. The wastewater in the spray chamber can be discharged through the drain pipe. The pre-treated exhaust gas enters the adsorption box through the first pipe. The activated carbon in the adsorption box adsorbs and filters the organic components in the exhaust gas. Then, it enters the CO furnace through the second pipe for high-temperature combustion to burn and decompose the pollutants in the exhaust gas.
[0015] Third, the purified air is discharged into the outside through the exhaust pipe. By opening the electronically controlled valve, a portion of the high-temperature gas in the exhaust pipe enters the adsorption box through the third pipe. The high-temperature gas can desorb and regenerate the activated carbon after adsorbing the waste gas, making the activated carbon reusable, saving usage costs and improving resource utilization.

[0025] In this embodiment, exhaust gas enters the filter tank 31 through the inlet pipe 6. The partition 32 divides the interior of the filter tank 31 into a spray chamber and a filtration chamber. Water is supplied to the spray pipe 34 via the water supply pipe 33. The water is sprayed out through the atomizing nozzle at the bottom of the spray pipe 34, forming a water mist that initially filters odors and particulate matter in the exhaust gas within the spray chamber. Simultaneously, the outlet of the microbubble generator is connected to the spray pipe 34. When the microbubble water is sprayed out through the spray pipe 34, the microbubbles carry the water flow and are evenly distributed within the spray chamber, enhancing the contact between the bubbles and the liquid and improving the treatment effect. Then, the exhaust gas enters the filtration chamber through the vent in the middle of the partition 32. Two filter plates 35 filter the water vapor and oil mist in the exhaust gas, pre-treating the exhaust gas before activated carbon adsorption and preventing... To prevent particulate matter and oil mist in the waste gas from affecting the adsorption effect of activated carbon, wastewater in the spray chamber can be discharged through drain pipe 36.

Then, it enters the CO furnace 5 through the second pipe 4 for high-temperature combustion, which decomposes the pollutants in the waste gas. The purified air is discharged to the outside through the exhaust pipe 7. By opening the electric control valve 9, a portion of the high-temperature gas in the exhaust pipe 7 enters the adsorption box 1 through the third pipe 8. The high-temperature gas can desorb and regenerate the activated carbon after adsorbing the waste gas, making the activated carbon reusable, saving usage costs, and improving resource utilization.

[0027] In this embodiment, the motor 10 is bolted to the bottom of the adsorption box 1. The motor 10 is turned on by the external controller, so that the motor 10 drives the lead screw 11 to rotate, thereby achieving the lifting effect of the lifting plate 12.
[0028] Specifically, three mesh cylinders 13 are bolted to the top of the lifting plate 12, and activated carbon is added inside the mesh cylinders 13.
[0029] In this embodiment, the mesh cylinder 13 is bolted to the top of the lifting plate 12 for storing activated carbon. The lifting plate 12 is raised to facilitate the addition and replacement of activated carbon.
[0030] Specifically, a sealing door 14 is rotatably installed on the top of the adsorption box 1, and a support rod 15 is inserted into one side of the lifting plate 12.
[0031] In this embodiment, by opening the sealing door 14, the placement net cylinder 13 is raised above the adsorption box 1, and the lifting plate 12 is guided and limited by the support rod 15, thereby improving the stability of the lifting plate 12 and the placement net cylinder 13 when they move.

[0033] In this embodiment, the drain end of the water pump 16 is connected to one end of the water supply pipe 33. The water pump 16 draws water from the water tank 17 and delivers it to the water supply pipe 33 to supply water to the spray pipe 34.

The filter screen 19 is installed in the mounting block 18 inside the water tank 17, which is convenient for installation and removal. The filter screen 19 can filter the water entering the water tank 17 and remove impurities from the water.
[0036] Working steps: 1. Exhaust gas enters the filter tank 31 through the inlet pipe 6. The baffle 32 divides the interior of the filter tank 31 into a spray chamber and a filter chamber. The water supply pipe 33 delivers water to the spray pipe 34. The water is sprayed out through the atomizing nozzle at the bottom of the spray pipe 34. The sprayed water forms a water mist to perform preliminary filtration of odors and particulate matter in the exhaust gas in the spray chamber. At the same time, the outlet of the microbubble generator is connected to the spray pipe 34. When the microbubble water is sprayed out through the spray pipe 34, the microbubbles carry the water flow and are evenly distributed in the spray chamber, which enhances the contact between the bubbles and the liquid and improves the treatment effect.
[0037] Second, the exhaust gas then enters the filtration chamber through the ventilation holes in the middle of the partition 32. The water vapor and oil mist in the exhaust gas are filtered by two filter plates 35, which pre-treats the exhaust gas before activated carbon adsorption to prevent particulate matter, oil mist and other components in the exhaust gas from affecting the adsorption effect of activated carbon. The wastewater in the spray chamber can be discharged through the drain pipe 36. The pre-treated exhaust gas enters the adsorption box 1 through the first pipe 2.

By opening the electric control valve 9, a portion of the high-temperature gas in the exhaust pipe 7 enters the adsorption box 1 through the third pipe 8. The high-temperature gas can desorb and regenerate the activated carbon after adsorbing the waste gas, making the activated carbon reusable, saving usage costs and improving resource utilization.
