Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically a circulating harmful gas adsorption and removal device. Background Technology

[0002] Harmful gases refer to gases that exist in the air and pose a threat to human health or the environment. Common harmful gases include: Formaldehyde: mainly from furniture, decoration materials, and home appliances. Long-term exposure to high concentrations of formaldehyde can cause headaches, insomnia, allergies, and other discomforts, and in severe cases, may even lead to cancer. Benzene: mainly from paints, coatings, and gasoline. High concentrations of benzene can cause dizziness and nausea, and long-term exposure can increase the risk of diseases such as leukemia. Carbon dioxide: a common indoor air pollutant, mainly from human respiration and combustion. High concentrations of carbon dioxide can cause headaches and difficulty concentrating. Ozone: a common pollutant that exists in the air for a short time. These harmful gases are not only harmful to the human body, but large-scale emissions also have a serious impact on the atmospheric environment, thus requiring the treatment of harmful gas adsorption and removal devices.

[0003] Existing circulating harmful gas adsorption and removal devices only adsorb harmful gases in the air through activated carbon adsorption plates. However, this method is not ideal for removing harmful gases from the air and cannot ensure that the emitted air meets emission standards. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figure 1-5This utility model provides a technical solution: a circulating harmful gas adsorption and removal device, the structure of which includes a box body 1, a base 2 fixedly connected to the bottom of the box body 1, pulleys 3 fixedly installed at the four corners of the bottom of the base 2, a door panel 4 rotatably connected to the front of the box body 1, a controller 5 fixedly connected to one side of the front of the box body 1, an air inlet pipe 6 fixedly connected to the top of the box body 1, a filter shell 7 threadedly connected inside the air inlet pipe 6, an exhaust pipe 8 connected to the bottom of one side of the box body 1, an exhaust valve 9 fixedly connected to the surface of the exhaust pipe 8, an installation plate 10 fixedly connected inside the box body 1, a circulating spray mechanism 11 is provided between the top side and the bottom of the installation plate 10, a gas circulation mechanism 12 is provided between the other top side and the bottom of the installation plate 10, and inserts 13 are fixedly connected to both sides inside the box body 1. The inserts 13 are configured in two sets, one set of inserts 13 with activated carbon plates 14 inserted between them, and the other set of inserts 13 with bamboo charcoal plates 15 inserted between them.

[0030] Both the activated carbon plate 14 and the bamboo charcoal plate 15 are located on the back of the door panel 4, with the activated carbon plate 14 located on the top side of the bamboo charcoal plate 15. Through the adsorption of the activated carbon plate 14 and the bamboo charcoal plate 15, some of the harmful substances in the gas can be adsorbed, thus purifying the gas.

[0031] The top of the mounting plate 10 is fixedly equipped with an air extractor 16. The top of the air extractor 16 is connected to an air extraction pipe 17, and the front of the air extractor 16 is connected to an air blowing pipe 18. One end of the air blowing pipe 18 passes through the top wall of the mounting plate 10 and extends to the bottom side of the mounting plate 10. The air extractor 16 can not only create a negative pressure inside the box 1 to draw outside gas into the box 1, but also draw the gas drawn back by the air pump 125 to the bottom side of the spray pipe 113 for spraying.

[0032] The circulating spraying mechanism 11 includes a water tank 111, which is fixedly connected to the top of the mounting plate 10. A first water pump 112 is fixedly connected inside the water tank 111. The output end of the first water pump 112 is connected to a spray pipe 113. One end of the spray pipe 113 passes through the top wall of the mounting plate 10 and extends to the bottom side of the mounting plate 10. An atomizing nozzle 114 is connected to the bottom of the spray pipe 113.

[0033] The second water pump 115 is fixedly installed inside the housing 1. The output end of the second water pump 115 is connected to a connecting pipe 116. The top end of the connecting pipe 116 passes through the bottom wall of the mounting plate 10 and is fixedly connected to the surface of the water tank 111. The first water pump 112 draws water out of the water tank 111 and sprays the water out using the spray pipe 113 and the atomizing nozzle 114. The sprayed water can spray the air that is drawn in, thereby adsorbing harmful substances in the air and thus purifying the air to a certain extent. The sprayed water can be recycled after being adsorbed by the adsorption plate 117. The second water pump 115 is started to draw the adsorbed water into the water tank 111 through the connecting pipe 116 for recycling.

[0034] The circulating spray mechanism 11 also includes an adsorption plate 117, which is fixedly connected to the bottom side of the mounting plate 10. The adsorption plate 117 is located between the second water pump 115 and the atomizing nozzle 114. One side of the adsorption plate 117 is made of activated carbon material, and the other side of the adsorption plate 117 is made of ion membrane. The adsorption plate 117 can adsorb and purify the water that falls from the spray. The water is first adsorbed by activated carbon and then filtered by ion membrane, so that the water after spraying can be purified and convenient for subsequent recycling.

[0035] The bottom side of the box 1 is connected to a drain pipe 118, and a drain valve 119 is fixedly connected to the surface of the drain pipe 118. With the drain pipe 118 and the drain valve 119, not only can the water in the box 1 be drained, but water can also be added from an external water pipe, making it flexible and versatile.

[0036] The gas circulation mechanism 12 includes a partition 121, which is fixedly connected to the bottom of the mounting plate 10. A through hole 122 is provided on the top side of the partition 121. A baffle 123 is fixedly connected to the bottom of the mounting plate 10. The baffle 123 is located between one side of the partition 121 and the atomizing nozzle 114. An air quality monitor 124 is fixedly connected to the other side of the partition 121. The baffle 123 can block the through hole 122 on the partition 121 to prevent the sprayed water mist from passing through the through hole 122 and entering the other side of the partition 121. The baffle 123 can also block the blown gas, reducing the amount of gas that passes directly through the through hole 122 and enters the other side of the partition 121 without being sprayed. The air quality monitor 124 can monitor the purified gas in real time, which facilitates the controller 5 to control the opening and closing of the exhaust pipe 8.

[0037] The gas circulation mechanism 12 also includes an air pump 125, which is fixedly connected to the top of the mounting plate 10. The top of the air pump 125 is connected to a circulation pipe 126, one end of which passes through the top wall of the mounting plate 10 and extends to one side of the air quality monitor 124.

[0038] During operation, when the device adsorbs harmful gases, the first step is to start the exhaust fan 16 via the controller 5. The exhaust fan 16 creates a negative pressure inside the housing 1, allowing outside air to enter through the intake pipe 6. As the air passes through the intake pipe 6, it is filtered by the filter shell 7, removing large particles and other impurities. The air then passes sequentially through the activated carbon plate 14 and the bamboo charcoal plate 15 for adsorption. The adsorbed air is then drawn from the top of the mounting plate 10 to the bottom by the exhaust pump 125. The air is drawn in through the extraction pipe 17 and discharged through the blowing pipe 18. The air blown to the bottom of the mounting plate 10 is sprayed through the circulating spray mechanism 11, which can further adsorb harmful substances in the air. After the air quality monitor 124 detects that the adsorbed air meets the standard, the controller 5 opens the exhaust valve 9, so that the air is discharged from the box 1 through the exhaust pipe 8. If the air quality monitor 124 detects that the adsorbed air does not meet the standard, the controller 5 starts the gas circulation mechanism 12 to draw the air to one side of the air extractor 16 for re-blowing and spraying until the air quality meets the standard.

[0039] When the circulating spray mechanism 11 is in operation, the first water pump 112 is started first. The first water pump 112 draws water from the water tank 111 and sprays the water out through the spray pipe 113 and the atomizing nozzle 114. The sprayed water can spray the air that is drawn in, thereby adsorbing harmful substances in the air and thus purifying the air. The sprayed water can be recycled after being adsorbed by the adsorption plate 117. The second water pump 115 is started to draw the adsorbed water back to the water tank 111 through the connecting pipe 116 for recycling. The circulating spray mechanism 11 can further purify the air and purify and recycle the water source, saving water resources. The water in the tank 1 can be discharged through the drain pipe 118 by opening the drain valve 119.

[0040] When the gas circulation mechanism 12 is working, the air pump 125 is started first. The air pump 125 draws the gas from the bottom side of the box 1 to one side of the air extractor 16 through the circulation pipe 126. Then, the air extractor 16 draws the gas to the bottom side of the atomizing nozzle 114 for spraying. The sprayed gas passes through the through hole 122 and enters the other side of the partition 121. This process is repeated to circulate and spray the gas until it meets the standard and is then discharged from the box 1.
