Description

Technical Field

[0002] Zeolite rotor exhaust gas purification devices are used in industrial production to treat organic waste gas; their main function is to adsorb and concentrate organic waste gas to facilitate subsequent processing; organic waste gas mainly comes from industries such as petrochemicals, pharmaceuticals, printing, coating, leather processing or chemical fiber production, and plastics processing.

[0003] A search revealed that Chinese patent CN218221773U discloses a zeolite rotor exhaust gas purification device, which belongs to the technical field of exhaust gas treatment and has the effect of improving the adsorption capacity of the zeolite rotor.

[0004] In actual use, the zeolite rotor exhaust gas purification device described above treats exhaust gas by direct spraying. During the spraying process, the water droplets generated by atomization adsorb some of the impurities in the exhaust gas. However, the impurities in the exhaust gas are very small, and even after atomization, a large number of impurities will still flow to the subsequent treatment section. Therefore, it is necessary to design a high-efficiency spray adsorption structure that can increase the exhaust gas adsorption area to solve this problem. Utility Model Content

A channel opening is provided at the top of the first vertical partition, and a plurality of wet curtain adsorption components are staggeredly installed on one side of the first vertical partition near the position of the air inlet pipe. Each wet curtain adsorption component is provided with a spraying mechanism at its top. A second vertical partition is connected between the bottom of the horizontal partition and the bottom inner wall of the purification treatment box. The top of the vertical partition has a water passage hole, and the second vertical partition divides the interior of the horizontal partition into a water storage chamber and a clean water chamber. The interior of the horizontal partition, located below the wet curtain adsorption assembly, has several water drop holes. A filter screen plate is installed on the inner wall of the middle part of the clean water chamber. A water pump is fixedly installed at the top of the purification treatment box. A water pump inlet is connected to the clean water chamber via a water suction pipe, and the water pump outlet is connected to an outlet pipe connected to multiple spray mechanisms. Mounting seats are provided on the outer wall of the other side of the first vertical partition and on the inner wall of the purification treatment box near the air outlet pipe. Support blocks are fixedly installed on the bottom inner walls of the two mounting seats. A lower support screen plate is installed above the support blocks. An adsorption filter plate is installed above the lower support screen plate, and an upper support screen plate is installed above the adsorption filter plate.

[0007] As a further improvement to the technical solution of this utility model, a control switch is installed on the outer wall of the purification treatment box near the lower position of the air inlet pipe, and a first door panel is connected to the front end of the purification treatment box at the position outside the water supply pipe. An observation window is installed inside the first door panel, and a second door panel is connected to the front end of the purification treatment box at the position outside the adsorption filter plate.

[0008] As a further improvement to the technical solution of this utility model, the bottom outer wall of the purification treatment box is provided with a drain outlet for discharging sewage inside the water storage chamber, and a water inlet is provided on the front bottom outer wall of the purification treatment box near the top of the water storage chamber.

[0009] As a further improvement to the technical solution of this utility model, the water pump is fixedly connected to the top of the purification treatment box by bolts, and the top of the purification treatment box is connected by screws to a number of limiting sleeves for supporting the water outlet pipe.

[0010] As a further improvement to the technical solution of this utility model, the wet curtain adsorption assembly includes two fixed plates symmetrically fixedly connected to the inner wall of the purification treatment box, and a frame connected between the two fixed plates. The frame is provided with a wet curtain inside, and the upper and lower ends of the frame are provided with a first T-shaped slider connected to the inner wall of the fixed plate. The inner wall of the fixed plate is provided with a first T-shaped groove in the horizontal direction corresponding to the outer side of the first T-shaped slider.

[0011] As a further improvement to the technical solution of this utility model, the spraying mechanism includes a water supply pipe connected to the water outlet pipe through a three-way pipe, and a horizontally arranged water collection pipe is connected to the bottom of the water supply pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a spray mechanism and several staggered wet curtain adsorption components, water is continuously sprayed onto the wet curtains of the wet curtain adsorption components. After the exhaust gas enters the purification treatment box through the air inlet pipe, some impurities in the exhaust gas can be adsorbed on the surface of the wet curtain and washed off by gravity through the top water spray treatment. The water enters the water storage chamber through the drain hole. The wet curtain adsorption components have a frame inside that can be easily slidably installed between two fixed plates, which is convenient for installation and disassembly. This keeps the wet curtain in a stable state and prevents positional displacement. It is also convenient for the operator to remove the frame to clean or replace the wet curtain. The multiple wet curtain adsorption components increase the contact area between the exhaust gas and the wet curtain, thereby effectively achieving high-efficiency adsorption of impurities in the exhaust gas, thus converting exhaust gas containing more impurities into cleaner exhaust gas with less impurities.

[0015] 2. The system is divided into a water storage chamber and a water purification chamber by the second vertical partition. As more water enters the water storage chamber, the water level rises and impurities settle. The settled impurities can prevent the subsequent pipes from becoming clogged. The clearer water at the top enters the water purification chamber through the water inlet. After being filtered by the filter screen, it is pumped out again and circulated for use by the spraying mechanism. Attached Figure Description

[0027] As attached Figure 1 and attached Figure 3-4 As shown, the wet curtain adsorption assembly 7 includes two fixed plates 701 symmetrically fixed to the inner wall of the purification treatment box 1.

[0030] Working principle: This utility model designs a zeolite purification device for waste gas with cleaning conversion, the specific structure of which is shown in the attached instruction manual. Figure 1-5As shown, in use, water is first injected into the water storage chamber 9 through the water inlet 26 until the water level is higher than the water outlet 12, then enters the clean water chamber, making the water level in the clean water chamber slightly lower than the water level in the water storage chamber 9. Then, a portion of the water in the water storage chamber 9 is released through the drain outlet 11. At this time, the water pump 14 operates to draw water from the clean water chamber and spray it onto the wet curtain 703 on the wet curtain adsorption assembly 7 through the spray mechanism, continuously spraying water onto the wet curtain 703. After the exhaust gas enters the purification treatment box 1 through the air inlet pipe 2, several staggered wet curtain adsorption assemblies 7 allow some impurities in the exhaust gas to be adsorbed onto the surface of the wet curtain 703. These impurities are then washed off by gravity through the top spray and enter the water storage chamber 9 through the drain hole 10. The frame 702 inside the wet curtain adsorption assembly 7, which contains the wet curtain 703, is easily slidably installed between two fixed plates 701 for convenient installation. The installation and removal of the wet curtain 703 ensures its stability and prevents positional shifts, allowing the operator to easily remove the frame 702 for cleaning or replacement. Multiple wet curtain adsorption components 7 increase the contact area between the exhaust gas and the wet curtain 703, effectively adsorbing impurities from the exhaust gas. As more water enters the water storage chamber 9, the water level rises, impurities settle, and the clearer water at the top enters the purified water chamber through the water passage 12. After being filtered by the filter plate 13, it is pumped out again by the water pump 14 for recycling. The exhaust gas adsorbed by the wet curtain 703 enters one side of the first vertical partition 6 through the channel 20, and is further purified by the upper support mesh plate 25, the adsorption filter plate 24, and the lower support mesh plate 23 before flowing from the outlet pipe 3 to the zeolite rotor. The upper support mesh plate 25 allows for easy and quick installation and removal, maintaining stability after installation, and facilitates the removal, cleaning, or replacement of the adsorption filter plate 24 after disassembly.

Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
