Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a high-efficiency, low-energy purification device for industrial waste gas. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] The prior art provides a high-efficiency, low-energy purification device for industrial waste gas (publication number CN212492254U), including a fixed frame, which is fixedly connected to a water pump. The water pump inlet is connected to the rear end of an inlet pipe, the front end of the inlet pipe is connected to a water tank, the upper surface of the water tank is connected to one end of a drain pipe, and the other end of the drain pipe is connected to the front surface of a first purification box. This high-efficiency, low-energy purification device for industrial waste gas uses the fixed frame to fix the motor, ensuring stable operation. Through the cooperation of the motor, a first gear, a second gear, and an outlet pipe, the first and second nozzles rotate and spray, increasing the contact area with the waste gas. The first and second purification boxes improve the purification effect. By using a filter screen and an activated carbon layer, the purified gas is discharged through the outlet pipe, further reducing waste gas emissions and protecting the environment.

[0004] Based on the above patent search, it is found that the above patents are not convenient for replacing the filter screen and activated carbon layer in actual use. Long-term use will cause the filter screen to become clogged and the activated carbon layer to become saturated, resulting in a decrease in the purification efficiency of the exhaust gas and failure to meet the emission standards. Therefore, we need to propose a high-efficiency and low-energy purification device for exhaust gas in industrial production. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency, low-energy purification device for industrial waste gas. By allowing for the replacement of components, the filter components can be easily replaced, preventing them from becoming saturated and ensuring they maintain their high-efficiency purification capabilities, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An efficient and low-energy purification device for industrial production waste gas includes a base plate 1, a first purification box 2 fixedly installed on the top of the base plate 1, and a spray assembly 3 for spraying and purifying waste gas inside the first purification box 2.

[0025] The top of the first purification box 2 is connected to the second purification box 4. The second purification box 4 is equipped with a filter assembly 5 for secondary filtration and adsorption of exhaust gas. A support plate 6 is fixedly installed on one side of the second purification box 4. A replacement assembly 7 is provided on the top of the support plate 6 to facilitate the replacement of the filter assembly 5.

[0026] The replacement component 7 includes two sets of fixed seats 71 fixedly installed on the top of the support plate 6. A movable plate 72 is slidably disposed inside each of the two sets of fixed seats 71. Two sets of positioning blocks 73 are installed on opposite sides of the two sets of movable plates 72. Pull rods 74 are respectively disposed on the sides of the two sets of movable plates 72 away from the positioning blocks 73. The two sets of pull rods 74 are slidably disposed on one side of each of the two sets of fixed seats 71. Two sets of return springs 75 are respectively sleeved on the outer sides of the two sets of pull rods 74. The replacement component 7 facilitates the replacement of the filter component 5. When replacing the filter screen 51 or the activated carbon layer 52, simply pull the pull rods 74 on both sides outwards; the pull rods 74 move the movable plates. When the positioning block 72 and positioning block 73 disengage from the positioning hole 56 of the fixing plate 55, the return spring 75 is compressed and stores elastic potential energy. Then, the fixing plate 55 is pulled out, and the old filter screen 51 or activated carbon layer 52 can be taken out through the through groove 54. Then, the new filter screen 51 or activated carbon layer 52 is inserted into the through groove 54. After the limiting groove 10 is aligned and locked with the limiting plate 9, the pull rod 74 is released. The elastic potential energy of the return spring 75 pushes the positioning block 73 to reset and re-lock the fixing plate 55, thereby ensuring the sealing after replacement. This solves the problem that it is not convenient to replace the filter component 5 in traditional purification equipment, and achieves efficient, stable and sustainable waste gas treatment effect.

[0027] Guide rods 8 are fixedly installed inside the two sets of fixed seats 71 respectively, and two sets of movable plates 72 are slidably arranged on the outside of the two sets of guide rods 8 respectively. Through the setting of the guide rods 8, the guide rods 8 provide a rigid sliding track for the movable plates 72, ensuring the alignment accuracy between the positioning block 73 and the positioning hole 56 of the fixed plate 55, avoiding manual adjustment deviation, and ensuring the sealing of the filter assembly 5 when it is replaced.

[0028] The filter assembly 5 includes a filter screen 51 and an activated carbon layer 52. Both the filter screen 51 and the activated carbon layer 52 are located inside the second purification chamber 4. The filter screen 51 is located directly below the activated carbon layer 52. A sealing plate 53 is provided on one side of the filter screen 51 and the activated carbon layer 52. Two sets of through grooves 54 are provided on one side of the second purification chamber 4 for replacing the filter screen 51 and the activated carbon layer 52. A fixing plate 55 is provided on the side of the two sets of sealing plates 53 away from the filter screen 51 and the activated carbon layer 52. The outer walls of the two sets of sealing plates 53 are respectively attached to the inner walls of the two sets of through grooves 54. Positioning holes 56 are provided on both sides of the two sets of fixing plates 55 for the insertion of positioning blocks 73. Through the arrangement of the filter assembly 5, the filter screen 51 is located directly below the activated carbon layer 52, forming a stepped interception. Large particles of dirt are first removed by the filter screen 51. The pollutants are then adsorbed by the activated carbon layer 52, which prevents impurities from clogging the pores of the activated carbon prematurely. The sealing plate 53 fits tightly against the inner wall of the channel 54, blocking the bypass path of unfiltered fluid, isolating the filter layer from the external environment, and preventing the backflow of pollutants during replacement. This ensures that all fluids are processed through the filter screen 51 and the activated carbon layer 52. The positioning block 73 is inserted and fixed with the positioning hole 56 to ensure accurate alignment of the components and prevent the sealing plate 53 from shifting and causing sealing failure. This allows for independent disassembly and assembly of the filter screen 51 or the activated carbon layer 52, enabling partial maintenance and replacement without disassembling the entire purification box. The external design of the fixing plate 55 facilitates unlocking the positioning block 73 from the outside, reducing the complexity of disassembling the internal structure. The two sets of channels 54 allow for simultaneous replacement or step-by-step maintenance of the filter screen 51 and the activated carbon layer 52.

[0029] Limiting plates 9 are installed on both sides of the interior of the second purification chamber 4. Limiting grooves 10 are opened on both sides of the filter screen 51 and the activated carbon layer 52 for the limiting plates 9 to engage. By setting the limiting plates 9 and the limiting grooves 10, the limiting grooves 10 on both sides of the filter screen 51 or the activated carbon layer 52 are engaged with the limiting plates 9. The tight engagement of the limiting plates 9 and the limiting grooves 10 can ensure that the filter screen 51 and the activated carbon layer 52 remain sealed and stable in the second purification chamber 4, which can reduce the risk of airflow short circuit and ensure that the exhaust gas can pass through the effective adsorption area of ​​the filter screen 51 and the activated carbon layer 52.

[0030] The spray assembly 3 includes a water tank 31 fixedly installed on the top of the base plate 1. A water pump 32 is fixedly installed on the top of the water tank 31. The inlet end of the water pump 32 is connected to the top of the water tank 31 through an inlet pipe. The outlet end of the water pump 32 is connected to an outlet pipe. The end of the outlet pipe away from the water pump 32 is connected to a U-shaped pipe 33. Both ends of the U-shaped pipe 33 pass through the first purification box 2 and are connected to water outlet plates 34. The two sets of water outlet plates 34 are respectively connected to multiple sets of nozzles 35 arranged in a rectangular array on opposite sides. Through the design of the spray assembly 3... The water pump 32 can be a Grundfos UPS series pump. The water pump 32 pumps the treatment liquid in the water tank 31 to the U-shaped pipe 33. The U-shaped pipe 33 is symmetrically connected to two sets of water outlet trays 34 to realize dual-path water supply and avoid uneven spraying caused by insufficient water pressure on one side. The water trays are located on both sides inside the first purification box 2 to form a counter-spraying effect, which enhances the contact strength between the liquid and the pollutants. In addition, with multiple sets of nozzles 35 arranged in a rectangular array, a larger area of ​​the first purification box 2 can be covered, further improving the purification effect on the exhaust gas.

[0031] The first purification chamber 2 is connected to an air inlet pipe 11 on one side, and the second purification chamber 4 is connected to an air outlet pipe 12 on the top. Through the arrangement of the air inlet pipe 11 and the air outlet pipe 12, the air inlet pipe 11 is connected to the first purification chamber 2 on the side, which reduces the impact of the airflow directly hitting the internal filter material, while the air outlet pipe 12 is set at the top and uses the principle of natural upward movement of hot airflow to accelerate the emission of purified gas.

[0032] Working principle: When this utility model is used, the exhaust gas enters the first purification box 2 through the air inlet pipe 11. After the spray assembly 3 is started, the water pump 32 pumps the treatment liquid in the water tank 31 to the U-shaped pipe 33, and distributes it evenly to multiple sets of nozzles 35 through the water outlet plate 34 to form atomized spray. The exhaust gas and the treatment liquid come into full contact, and the soluble pollutants are dissolved and settled, thereby completing the initial purification.

[0033] The waste gas treated by spraying rises to the second purification box 4, where it first passes through the filter screen 51 to intercept residual particulate matter, and then enters the activated carbon layer 52. The activated carbon removes gaseous pollutants through physical adsorption or chemical action, achieving deep purification. The waste gas that has undergone dual purification is discharged from the exhaust pipe 12 at the top of the second purification box 4.

[0034] When the filter screen 51 or activated carbon layer 52 needs to be replaced, pull the pull rods 74 on both sides outward. The pull rods 74 drive the moving plate 72 and the positioning block 73 to disengage from the positioning hole 56 of the fixed plate 55. At this time, the return spring 75 is compressed and stores elastic potential energy. Then, pull out the fixed plate 55, and the old filter screen 51 or activated carbon layer 52 can be taken out through the through groove 54. Then, insert the new filter screen 51 or activated carbon layer 52 into the through groove 54. After the limiting groove 10 is aligned and locked with the limiting plate 9, release the pull rod 74. The elastic potential energy of the return spring 75 pushes the positioning block 73 to reset and insert into the positioning hole 56 of the fixed plate 55, completing the quick locking and ensuring the sealing after replacement.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
