[0001] This utility model relates to the field of flue gas treatment technology, specifically a self-cleaning flue gas purification spray chamber. Background Technology

[0002] The carbonization process of bamboo charcoal produces a large amount of smoke. If the smoke is directly discharged into the atmosphere, it will seriously pollute the environment. Therefore, the smoke must be effectively treated before it is discharged in order to meet the emission standards. Traditional spray towers have dead corners during spraying, and the smoke can escape from the dead corners. Furthermore, it is difficult to detect the blockage of the nozzles, and it is also difficult to clean or replace the nozzles. Utility Model Content

[0003] The purpose of this invention is to provide a self-cleaning flue gas purification spray chamber to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning flue gas purification spray chamber, comprising a chamber body and a water pump, wherein an air inlet and an air outlet are respectively provided at the left and right ends of the chamber body, and a plurality of first partitions and second partitions are provided inside the chamber body, wherein the first partitions are fixedly connected to the top of the chamber body, the second partitions are fixedly connected to the bottom of the chamber body, and a second partition is provided between every two adjacent first partitions, wherein the flue gas entering the chamber body flows sequentially through the flow channel formed below the first partitions and above the second partitions;

[0006] Furthermore, it also includes a water tank located below the compartment, a water pump located above the water tank, and a filter installed at the water pump input end. The other end of the filter extends into the water tank. Each area at the bottom of the compartment, separated by various second partitions, is equipped with a water outlet pipe, the other end of which extends into the water tank. The input end of the second nozzle is connected to an extension pipe, the other end of which passes through the compartment and connects to a branch pipe.

[0007] Furthermore, the air outlet of the chamber is connected to a purification box, the other end of the purification box is provided with an output pipe, the purification box is filled with activated carbon, and the top and bottom of the purification box are detachably provided with sealing plates.

[0008] Furthermore, the top of the compartment is provided with an explosion-proof mechanism, which includes an explosion-proof cylinder, a pressure ring, and an explosion-proof membrane.

Detailed Implementation

[0016] 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.

[0017] like Figures 1 to 3 As shown, a self-cleaning flue gas purification spray chamber includes a chamber body 1 and a water pump 2. The left and right ends of the chamber body 1 are respectively provided with an air inlet 3 and an air outlet 4. The chamber body 1 is provided with a plurality of first partitions 5 and second partitions 6. The first partitions 5 are fixedly connected to the top of the chamber body 1, and the second partitions 6 are fixedly connected to the bottom of the chamber body 1. A second partition 6 is provided between every two adjacent first partitions 5. The flue gas entering the chamber body 1 flows sequentially through the flow channel formed below the first partitions 5 and above the second partitions 6.

[0018] Several first nozzles 7 and second nozzles 8 are respectively installed at the top and bottom of the interior of the compartment 1. The first nozzles 7 are located on the side of the first partition 5, and the second nozzles 8 are located on the side of the second partition 6. The input end of the water pump 2 is connected to an external water source, and the output end of the water pump 2 is connected to each of the first nozzles 7 and second nozzles 8 through several branch pipes 9.

[0019] In this embodiment, a water tank 10 is also included, located below the compartment 1. A water pump 2 is mounted on the water tank 10, and a filter 11 is installed at the input end of the water pump 2. The other end of the filter 11 extends into the water tank 10. Each area at the bottom of the compartment 1, separated by various second partitions 6, is equipped with a water outlet pipe 12, the other end of which extends into the water tank 10. An extension pipe 18 is connected to the input end of the second nozzle 8, and the other end of the extension pipe 18 passes through the compartment and connects to a branch pipe 9. The extension pipe 18 is essentially a… The function of the added pipe is to change the position of the second nozzle 8 through physical displacement. When the spray water is sprayed from the first nozzle 7 and the second nozzle 8 above, the water flow will naturally converge downwards and form a water accumulation layer at the bottom of the compartment (especially in the area separated by the second partition). If the water accumulation submerges the outlet of the second nozzle 8, the nozzle will fail due to backflow or blockage caused by water pressure. The extension pipe 18 ensures that the actual installation position of the second nozzle 8 is higher than the bottom of the compartment 1, thus preventing the second nozzle 8 from being directly submerged in the bottom water accumulation pool.

[0020] In this embodiment, the air outlet 4 of the chamber 1 is connected to the purification box 13, and the other end of the purification box 13 is provided with an output pipe. The purification box 13 is filled with activated carbon, and the top and bottom of the purification box 13 are detachably provided with sealing plates 17. When replacing the activated carbon, the bottom sealing plate 17 is pulled out, and the activated carbon in the purification box 13 will fall automatically under the action of gravity. After cleaning, the bottom sealing plate 17 is put back, and the top sealing plate 17 is pulled out, and activated carbon can be poured in through the top opening.

[0021] In this embodiment, an explosion-proof mechanism is provided on the top of the compartment 1. The explosion-proof mechanism includes an explosion-proof cylinder 14, a pressure ring 15, and an explosion-proof membrane 16. The explosion-proof cylinder 14 is installed on the top of the compartment 1 and communicates with the interior of the compartment 1. The pressure ring 15 is detachably installed on the top of the explosion-proof cylinder 14. An explosion-proof membrane 16 is provided between the pressure ring 15 and the explosion-proof cylinder 14. The explosion-proof membrane 16 is made of aluminum. If there is a blower failure, the activated carbon in the purification box 13 blocks the gas flow channel, or the water outlet pipe 12 is blocked, causing the water in the compartment 1 to be unable to flow out, the pressure inside the compartment 1 will rise abnormally as the flue gas continues to enter. At this time, the aluminum explosion-proof membrane 16 will rupture directionally at the moment of overpressure, and the gas will be released quickly through the explosion-proof cylinder 14, thereby preventing the overall structure of the compartment 1 from exploding.

[0022] In this embodiment, the top and bottom of the compartment 1 are respectively provided with several through holes corresponding to the first nozzle 7 and the second nozzle 8. The first nozzle 7 and the second nozzle 8 extend into the interior of the compartment 1 through the corresponding through holes. The branch pipe 9 is detachably connected to the first nozzle 7 and the second nozzle 8 by quick-connect couplings, and each branch pipe 9 is provided with an independent control valve. The control valve of each branch pipe 9 can be closed individually to cut off the water flow of the corresponding nozzle, so as to achieve maintenance without stopping the system (spraying in other areas continues to operate normally). With the quick-connect coupling, after closing the valve, the first nozzle 7 or the second nozzle 8 can be separated from the branch pipe, and the first nozzle 7 or the second nozzle 8 can be pulled out of the compartment 1 through the through hole. The nozzle can be quickly disassembled to clean blockages (such as dust clumps and scale) and avoid the overall system shutdown.

[0023] The working principle of this embodiment is as follows:

[0024] The flue gas is introduced into the chamber 1 by an induced draft fan. The flue gas enters the chamber 1 through the air inlet 3 and is guided by the alternating arrangement of the first baffle 5 (fixed at the top) and the second baffle 6 (fixed at the bottom) to form an "S-shaped" forced flow channel, thereby prolonging the residence time of the flue gas, increasing the probability of collision between particulate matter and the baffle, and achieving preliminary inertial separation. The first nozzle 7 is located on the side of the first baffle 5 and sprays water mist downward to cover the rising stage of the flue gas. The second nozzle 8 is located on the side of the second baffle 6 and sprays water mist upward to cover the falling stage of the flue gas. The water mist comes into full contact with the dust in the flue gas and achieves efficient removal through adsorption and condensation.

[0025] After spraying, the wastewater flows along the bottom of the compartment 1 into the collection area separated by the second partition 6, and is discharged into the water tank 10 below through the outlet pipe 12. A filter 11 is installed at the input end of the water pump 2 to intercept solid impurities when pumping wastewater from the water tank 10, preventing the nozzles from clogging. The filtered water is repressurized by the water pump 2 and delivered to the nozzles, forming a closed loop of "spraying → collection → filtration → reuse", which significantly reduces the amount of external water replenishment and wastewater discharge.

[0026] Finally, the gas purified by spraying enters the purification chamber 13 from the outlet 4, flows through the activated carbon layer to adsorb residual organic matter and odors, and is finally discharged as clean gas through the output pipe.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
