Description

Technical Field

[0001] This utility model relates to the field of environmental protection engineering construction technology, and in particular to a low-carbon treatment device for environmental protection engineering construction. Background Technology

[0002] With rapid industrialization and urbanization, environmental pollution problems have become increasingly serious, especially air pollution, water pollution, and solid waste pollution. Flue gas emitted from the chemical industry contains large amounts of carbon dioxide, and the incineration technology commonly used for solid waste also produces flue gas. Direct emission of these flue gas into the atmosphere causes air pollution. To address air pollution, environmental engineering projects utilize low-carbon treatment devices that primarily employ technologies such as desulfurization, denitrification, and dust removal.

[0003] A low-carbon treatment device for environmental engineering construction disclosed in application number 202221510928.0, although the utility model uses a treatment cylinder, hollow spheres, through holes, a partition, calcium hydroxide powder, a water storage tank, an air inlet pipe, and a second connecting pipe, can not only reduce carbon dioxide emissions but also fully utilize its products, reduce resource waste, and save costs. Furthermore, the calcium hydroxide powder is encased in hollow spheres, which, when stacked, create large gaps, allowing carbon dioxide to fully contact the calcium hydroxide powder and improving the low-carbon treatment effect. The water generated from carbon dioxide and calcium hydroxide powder is recycled through a recovery cylinder. The partition prevents calcium carbonate and calcium hydroxide powder from entering the recovery cylinder with the water flow. When the water source inside the water storage tank needs to be replaced, a water pump and the first connecting pipe draw clean water from the recovery cylinder into the water storage tank, enabling the reuse of the products generated from carbon dioxide and calcium hydroxide powder, further reducing resource waste and making it more energy-efficient and environmentally friendly.

[0004] However, when this utility model filters dust from flue gas by washing it with water, some dust particles may not have enough time to come into full contact with the water before being carried out of the treatment device when the processing wind speed is high or the dust concentration is high. Furthermore, when the water in the storage tank reaches saturation, the dust particles in the flue gas have difficulty finding an effective attachment point in the water and cannot be fully captured and removed by the water, thus affecting the overall dust removal effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, to solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-carbon treatment device for environmental protection engineering construction, which includes:

[0007] The dust removal unit includes a water washing tank, the inner wall of which is equipped with an arc-shaped pipe and a fixing block. A nozzle is installed on the arc-shaped pipe, and a filter plate is provided on the fixing block.

[0008] The reaction unit includes a reaction tank, a fixing frame is provided on the inner wall of the reaction tank, a powder bag is provided on the fixing frame, a water storage tank is installed at the bottom of the reaction tank, a tank top cover is installed at the top of the reaction tank, and an exhaust pipe is provided on the tank top cover.

[0009] The connection unit includes a mounting box, in which a drive water pump is installed. The input end of the drive water pump is connected to a water pumping pipe, one end of which is installed in a water storage tank. The output end of the drive water pump is connected to a water delivery pipe, one end of which is installed on an arc-shaped pipe.

[0010] As a preferred embodiment of the low-carbon treatment device for environmental protection engineering construction described in this utility model, the washing tub and the storage tub are connected by a connecting pipe, which is driven by a micro water pump. The micro water pump drives the water in the connecting pipe to enter the storage tub from the washing tub.

[0011] As a preferred embodiment of the low-carbon treatment device for environmental protection engineering construction described in this utility model, the top of the washing tub is equipped with a sealing cover, the bottom of the sealing cover is fixed with a partition plate, and the side of the partition plate is provided with a rubber gasket. Installing the sealing cover on the washing tub can maintain the airtightness of the washing tub. When flue gas is introduced, the flue gas is washed, filtered and dust-removed on one side of the partition plate, and then enters the other side from below the partition plate. The rubber gasket can increase the sealing performance of the partition plate and the inner wall of the washing tub.

[0012] As a preferred embodiment of the low-carbon treatment device for environmental protection engineering construction described in this utility model, the sealing cover is equipped with an air inlet pipe and an air outlet. An air outlet pipe is installed inside the air outlet. One end of the air outlet pipe is installed on the reaction tank. The flue gas is input into the water washing tank through the air inlet pipe, and the filtered and dust-removed flue gas is transported to the reaction tank through the air outlet pipe installed in the air outlet.

[0013] As a preferred embodiment of the low-carbon treatment device for environmental protection engineering construction described in this utility model, a filter screen is installed at the bottom of the air inlet, a rotating rod is rotatably connected to the center of the filter screen, a rotating plate is installed at the top of the rotating rod, and a cleaning brush is installed at the bottom of the rotating rod. When the flue gas after water washing enters the air inlet, the remaining dust that has not yet come into contact with the water is filtered by the filter screen. At the same time, the conveying of the flue gas causes the rotating plate to rotate, which in turn drives the cleaning brush to rotate around the rotating rod as the axis. When the cleaning brush rotates, it can brush off the dust in the filter holes of the filter screen, preventing dust accumulation and clogging of the filter screen.

[0014] As a preferred embodiment of the low-carbon treatment device for environmental protection engineering construction described in this utility model, the surface of both the washing tub and the storage tub is equipped with a drain pipe, and a valve is installed on the drain pipe. When the valve is opened, the water in the washing tub and the storage tub can be discharged through the drain pipe.

[0015] The beneficial effects of this utility model are:

[0016] During use, flue gas enters from one side of the washing tank. After being adsorbed by the water sprayed from the nozzle, the flue gas enters the other side of the washing tank. Dust particles in the flue gas that have not yet come into contact with the water are further filtered by the filter screen. While the flue gas is flowing, the cleaning brush cleans the filter screen to prevent clogging. Through the dual effect of water washing and physical filtration, dust particles in the flue gas are removed, avoiding the omissions caused by single filtration. Moreover, the adsorption effect will not reach saturation during water washing, preventing dust particles that cannot be effectively attached from escaping, thus improving the dust removal effect of this device.

[0030] Example 1

[0031] Reference Figure 1 -5, the first embodiment of this utility model, provides a low-carbon treatment device for environmental engineering construction, the structure of which includes:

[0032] The dust removal unit 100 includes a washing tank 101. An arc-shaped pipe 102 and a fixing block 103 are installed on the inner wall of the washing tank 101. A nozzle 104 is installed on the arc-shaped pipe 102, and a filter plate 105 is installed on the fixing block 103. The filter plate 105 is fixed in place by the fixing block 103. Water from a water storage tank 204 is pumped to the arc-shaped pipe 102 by a driving water pump 302. Water is sprayed out through the nozzle 104 and mixes with the flue gas, adsorbing dust particles in the flue gas. Water and dust fall onto the filter plate 105 and are filtered by the filter plate 105. Dust particles remain above the filter plate 105, while water accumulates below the washing tank 101, causing solid-liquid separation. The washing tank 101 and the water storage tank 204 are connected by a connecting pipe 1011, which is driven by a micro water pump 1012. A sealing cover 1013 is installed on the top of the washing tank 101, and a sealing cover 1013 is fixed to the bottom of the sealing cover 1013. A partition plate 1013a is provided with a rubber pad 1013b on its side; an air inlet pipe 1013c and an air outlet are installed on the sealing cover 1013, and an air outlet pipe 1013d is installed inside the air outlet pipe, with one end of the air outlet pipe 1013d installed on the reaction tank 201; a filter screen 1013e ​​is installed at the bottom of the air outlet, and a rotating rod 1013f is rotatably connected to the center of the filter screen 1013e; a rotating plate 1013g is installed at the top of the rotating rod 1013f, and a cleaning brush 1013h is installed at the bottom of the rotating rod 1013f; a drain pipe 1014 is installed on the surface of both the water washing tank 101 and the water storage tank 204, and a valve 1015 is installed on the drain pipe 1014; through the dual reinforcement of water washing and filtration by the dust removal unit 100, the dust in the flue gas is filtered to prevent dust particles from entering the reaction tank 201 and affecting the subsequent reaction of the flue gas, resulting in better dust removal effect.

[0033] The reaction unit 200 includes a reaction tank 201. A fixing frame 202 is provided on the inner wall of the reaction tank 201. A powder pack 203 is provided on the fixing frame 202. A water storage tank 204 is installed at the bottom of the reaction tank 201. A tank top cover 205 is installed on the top of the reaction tank 201. An exhaust pipe 206 is provided on the tank top cover 205. The flue gas is transported into the reaction tank 201 by the gas supply pipe 1013d. The gas rises and passes through the fixing frame 202, where it reacts chemically with the powder in the powder pack 203 on the fixing frame 202. The calcium hydroxide powder in the powder pack 203 reacts with the carbon dioxide in the flue gas to produce calcium carbonate and water. The calcium carbonate remains on the fixing frame 202, while the water drips into the water storage tank 204. The purified flue gas is discharged through the exhaust pipe 206 on the tank top cover 205.

[0034] The connection unit 300 includes a mounting box 301, in which a drive water pump 302 is installed. The input end of the drive water pump 302 is connected to a pumping pipe 303, one end of which is installed in a water storage tank 204. The output end of the drive water pump 302 is connected to a water delivery pipe 304, one end of which is installed on an arc-shaped pipe 102. The drive water pump 302 is installed and fixed in place by the mounting box 301. When the drive water pump 302 is started, water in the water storage tank 204 is drawn out through the pumping pipe 303 and delivered to the arc-shaped pipe 102 via the water delivery pipe 304.

[0035] During use, firstly, the sealing cover 1013 is installed on the washing tub 101. The flue gas is introduced into the washing tub 101 through the air inlet pipe 1013c. Then, the drive water pump 302 is started to transport the water in the storage tank 204 to the arc-shaped pipe 102 and spray it out through the nozzle 104. The water wash adsorbs the dust particles in the flue gas. The sewage falls on the filter plate 105 and is filtered by the filter plate 105. The dust particles are retained above the filter plate 105. The water accumulates below the washing tub 101 to separate the solid and liquid. The filtered clean water can be discharged through the drain pipe 1014 or pumped into the storage tank 204 for recycling by the micro water pump 1012.

[0036] Then, the flue gas enters the other side from below the partition plate 1013a. The filtered and dust-removed flue gas is transported to the reaction tank 201 through the gas supply pipe 1013d installed in the gas supply port. The remaining dust that has not yet come into contact with water is filtered by the filter screen 1013e. At the same time, the transport of flue gas causes the rotating plate 1013g to rotate, which in turn drives the cleaning brush 1013h to rotate around the rotating rod 1013f as the axis. When the cleaning brush 1013h rotates, it can brush off the dust in the filter holes on the filter screen 1013e, preventing dust accumulation and clogging of the filter screen 1013e.

[0037] Finally, the flue gas after dust removal enters the reaction tank 201. The gas rises and passes through the fixed frame 202, where it reacts chemically with the powder in the powder pack 203 on the fixed frame 202. The calcium hydroxide powder in the powder pack 203 reacts with the carbon dioxide in the flue gas to produce calcium carbonate and water. The calcium carbonate remains on the fixed frame 202, while the water drips into the water storage tank 204. The purified flue gas is then discharged through the exhaust pipe 206 on the top cover 205 of the tank.

[0038] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
