Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an environmentally friendly greenhouse waste gas treatment device. Background Art

[0002] Agricultural greenhouses, also known as greenhouses, are facilities used to grow crops. They are usually composed of metal or plastic frames and covering materials, such as glass, polyethylene film, etc. During the use of agricultural greenhouses, a large amount of waste gas will be generated. The greenhouse waste gas mainly comes from the gases released during the growth of crops, the gases generated by soil microbial activities, and the use of agricultural inputs such as pesticides and fertilizers. These waste gases may contain harmful gases such as ammonia, hydrogen sulfide, and methane. If they are not treated and directly discharged into the atmosphere, they will pollute the environment and even harm human health. Therefore, treating greenhouse waste gas is beneficial to environmental protection.

[0003] The utility model patent with authorization announcement number CN213121795U discloses an exhaust gas monitoring device for a breeding greenhouse. The exhaust gas monitoring device for a breeding greenhouse includes a casing, an air intake box is provided on one side wall of the casing, an air intake dust filter is provided on one side wall of the air intake box, a first fan is provided in the inner cavity of the air intake box, an exhaust gas monitoring device is provided on the side of the inner cavity of the casing close to the air intake box, air guide hoppers are provided on both sides of the exhaust gas monitoring device, and the air guide hoppers away from the air intake box are connected to a diversion box, and a plurality of diversion grooves are equidistantly provided in the inner cavity of the diversion box, a driving motor is provided on the top of the casing, a transmission shaft is provided on the output end of the driving motor, the transmission shaft passes through the top of the casing and extends to the bottom of the inner cavity of the casing, a fresh box is provided on one side of the transmission shaft, a liquid guide tube is provided on the inner wall of the top of the casing, a sealing plug is provided on the top of the casing, and a second fan is symmetrically provided on the side of the fresh box away from the transmission shaft. By setting up a driving motor, the transmission shaft and the activated carbon adsorption plate and the nano sterilization catalytic plate thereon can be driven to rotate and come into contact with the exhaust gas. By setting up the activated carbon adsorption plate, the exhaust gas can be adsorbed and purified. The rotating activated carbon adsorption plate can increase the contact area with the exhaust gas and improve the adsorption capacity. By setting up the nano sterilization catalytic plate, the bacteria carried in the exhaust gas can be eliminated. The exhaust gas after purification and filtration enters the freshness box.

[0004] Although the exhaust gas monitoring device used in the breeding greenhouse can adsorb and purify the exhaust gas through the activated carbon adsorption plate, the device still has the following problems in actual use: the activated carbon adsorption plate provided in the device is installed on the drive shaft. Although it can be rotated to improve the filtering effect, the activated carbon adsorption plate is difficult to disassemble and assemble. The activated carbon adsorption plate has a certain service life. If it is not replaced for a long time, the adsorption effect of the activated carbon adsorption plate will decrease or fail, thereby reducing the filtering effect of the exhaust gas. In view of this, we propose an environmentally friendly greenhouse exhaust gas treatment device. Utility Model Content

A strip groove 171 is provided at the bottom of the fixed plate 17, and two guide rods 173 are fixed in the strip groove 171. A slider 175 is slidably installed below the two guide rods 173. A spring 174 for pressing against the slider 175 is sleeved on the outside of the guide rod 173. An insert block 176 is fixed at the bottom center of the slider 175. The insert block 176 passes through the fixed plate 17 and is plugged into the corresponding slot 121.

[0031] In this embodiment, a connection groove 172 is provided on the right end surface of the fixing plate 17, and a dial plate 177 is slidably installed in the connection groove 172, and the dial plate 177 is fixedly connected to the slider 175. The dial plate 177 facilitates the lifting and lowering of the slider 175, improves the convenience of operation, and facilitates the disassembly and assembly of the fixing plate 17.

[0032] In this embodiment, a material taking port 162 is provided on the left end surface of the housing 16, and the cross-sectional shape of the material taking port 162 is rectangular. The material taking port 162 facilitates the taking out of the filter layer 163 for replacement, thereby improving the convenience of operation.

[0033] In this embodiment, a handle 178 is installed on the right end surface of the fixing plate 17, and the handle 178 is fixedly connected to the fixing plate 17 by bolts. The setting of the handle 178 facilitates pulling the fixing plate 17, improves the convenience of operation, and has a humanized design.

[0034] In this embodiment, the overall shape of the connecting pipe 13 is U-shaped, and both ends of the connecting pipe 13 are fixedly connected to the connecting chamber 11 by bolts. This design facilitates the connection pipe 13 to transport the exhaust gas between the two connecting chambers 11 to filter the exhaust gas.

[0035] In this embodiment, the overall shape of the air intake pipe 14 and the exhaust pipe 15 are both L-shaped, and the air intake pipe 14 and the exhaust pipe 15 are both made of aluminum alloy. The arrangement of the air intake pipe 14 and the exhaust pipe 15 is conducive to the exhaust gas entering and exiting the connecting chamber 11.

[0036] It can be understood that a partition 19 is installed at the rear end of the interior of the clean air box 1 in this embodiment, and the air intake pipe 14 passes through the partition 19 and is connected to the air intake port. This design facilitates the partitioning of the interior of the clean air box 1, thereby facilitating the entry and discharge of exhaust gas.

[0037] It should be added that the filter layer 163 in this embodiment is activated carbon particles, which can filter greenhouse exhaust gas. The activated carbon particles have a huge specific surface area and rich pore structure, which can provide a large number of adsorption sites for harmful substances in the exhaust gas. When the exhaust gas passes through the filter layer 163, the activated carbon particles will quickly capture and adsorb these harmful substances, effectively purify the exhaust gas, and reduce its harm to the environment and human body.

[0038] When in use, the user first connects the power supply of the ventilator 18, and the ventilator 18 starts to work and guides the air flow. The exhaust gas in the greenhouse enters the rear side of the inner cavity of the clean air box 1 through the air inlet, and at the same time, the exhaust gas enters the connecting bin 11 through the air inlet pipe 14. At the same time, the exhaust gas passes through the support net 161 and enters the shell 16. At this time, the exhaust gas passes through the filter layer 163, and the filter layer 163 quickly captures and absorbs harmful substances in the exhaust gas. The filtered exhaust gas continues to move through the connecting pipe 13 and passes through multiple filter layers 163 in turn. The harmful substances in the exhaust gas are adsorbed multiple times. Finally, the filtered exhaust gas is discharged to the inside of the clean air box 1 through the air inlet pipe 14, and is discharged to the outside through the exhaust port;

[0039] When the filter layer 163 needs to be replaced, the user first pushes the dial plate 177 upwards, and the dial plate 177 drives the slider 175 to move upward along the two guide rods 173. The spring 174 is compressed by the slider 175, and the slider 175 simultaneously drives the plug 176 to disengage from the slot 121. Then the user holds the handle 178 and pulls it, and the fixing plate 17 drives the shell 16 to move forward. When the shell 16 is separated from the connecting bin 11, the user takes out the filter layer 163 in the shell 16 through the material extraction port 162 and replaces it.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
