Description

Technical Field

[0001] This utility model relates to the field of deodorization device technology, and in particular to a tail gas deodorization device for incineration dry toilets. Background Technology

[0002] Gaseous pollutants produced by feces can cause serious air pollution. These gaseous pollutants have low thresholds. Inhaling a small amount of gas can irritate and corrode the human upper respiratory tract, causing congestion and edema of the conjunctiva, respiratory tract, and nasopharyngeal mucosa. Inhaling large amounts of high-concentration malodorous gases can cause serious damage to human organs.

[0003] Existing chemical deodorization devices involve gas-liquid contact, which transfers the gaseous odor components to the liquid phase, and then uses chemical agents to oxidize or otherwise react with the odor components to remove the odor substances. However, the media has a short service life (once it is saturated, it needs to be regenerated or even replaced), the treatment efficiency is unstable, and the treatment efficiency for high-concentration odors is low.

[0004] Existing biological deodorization devices use biological packing as a carrier to maintain the life activities of microbial communities by degrading malodorous substances and decomposing malodorous substances into odorless substances such as carbon dioxide, water, and minerals, thereby achieving the purpose of purifying malodorous gases. However, due to the low rate of oxidation and decomposition, biological deodorization requires a large space. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as unstable processing efficiency of chemical deodorization devices, low efficiency in treating high-concentration odors, low oxidation and decomposition rate of biological deodorization devices, and the need for large spaces for biological deodorization. Therefore, this invention proposes a tail gas deodorization device for incineration-type dry toilets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An exhaust gas deodorization device for incineration dry toilets includes an outer cylinder, an air outlet is provided on one side of the outer wall of the outer cylinder, and an air inlet pipe is fixedly connected to the end of the outer cylinder away from the air outlet.

[0008] End cap, used to mate with the end of the outer cylinder away from the air intake pipe;

[0009] The deodorization unit is used to deodorize the exhaust gas. The deodorization unit is located inside the outer cylinder. The deodorization unit includes five filling cylinders. The five filling cylinders are respectively filled with fine sand, activated carbon, precious metal catalyst, biological filler and activated carbon from the direction from the air inlet pipe to the end cap.

[0010] A mounting bracket is used to install the deodorization unit. The mounting bracket is located between the air inlet pipe and the air outlet pipe. The mounting bracket includes a lower half ring bracket and an upper half ring bracket. The upper half ring bracket is fixedly installed at the top of the inner wall of the outer cylinder, and the lower half ring bracket is slidably installed at the bottom of the inner wall of the outer cylinder.

[0011] A bracket is used to fix the filling cylinder, and the bracket is located between the mounting bracket and the end cap.

[0012] In one possible design, the vent hole of the outer cylinder is fixedly connected to an vent pipe with a mounting flange ring.

[0013] In one possible design, both ends of the filling cylinder are provided with breathable mesh.

[0014] In one possible design, the end cap has a concave surface on the side near the outer cylinder, and the inner wall of the concave surface near the outer cylinder has a threaded groove.

[0015] In one possible design, the inner wall of the threaded groove mates with one end of the outer wall of the outer cylinder.

[0016] In one possible design, rubber pads are provided between adjacent filling cylinders.

[0017] In one possible design, a plurality of limiting rods are fixedly provided on the side of the bracket near the lower half ring frame, and a plurality of limiting grooves are opened on the side of the lower half ring frame near the bracket, and the plurality of limiting rods slide into the interior of the limiting grooves respectively.

[0018] In this application, during actual use, the air inlet pipe at one end of the outer cylinder is connected to the toilet incineration chamber, and the air outlet pipe is connected to the air inlet of the blower. This achieves the overall process of drawing combustion exhaust gas from the toilet into the interior of the outer cylinder through the blower, then through the interior of the deodorization unit, and finally discharging it. Specifically, the exhaust gas generated by combustion has a high temperature and contains many particulate impurities. Larger particulate impurities are initially filtered by fine sand, and most of the exhaust gas can be adsorbed by activated carbon through physical adsorption. The precious metal catalyst further removes waste through chemical reaction, and finally, the exhaust gas is removed more completely by biological filling material. Finally, activated carbon can adsorb the harmless gas after conversion. The precious metal catalyst has a high catalytic efficiency at 120℃-180℃, while the biological filling material can exert its catalytic activity at 30℃-50℃. The fine sand and activated carbon at the front end can significantly reduce the temperature of the exhaust gas, allowing the gas to enter the chemical catalyst and biological active material at a predetermined temperature.

[0019] When installing the filling cylinders onto the inner wall of the lower half-ring frame, multiple filling cylinders are placed through the deodorization process described above, and rubber pads are placed between multiple adjacent filling cylinders. Then, the bracket is pushed to move the lower half-ring frame into the inner wall of the outer cylinder. After the bracket is moved to the designated position, the end cap is threaded onto one end of the outer cylinder. At this time, because rubber pads are placed between multiple filling cylinders, the total length of the filling cylinders and rubber pads will be slightly longer than the inner wall of the lower half-ring frame, causing them to protrude slightly. When the end cap is reinstalled, the end cap will squeeze the rubber pads between multiple filling cylinders through the bracket, causing them to deform to a certain extent, thereby supporting and fixing multiple filling cylinders and increasing stability.

[0020] The gas in the combustion chamber is drawn in through the air inlet cylinder by a blower, and then enters each deodorization unit through small holes on the deodorization unit to adsorb the malodorous components in the gas. The deodorized gas then enters the centrifugal blower through the exhaust port limiting groove, and is then discharged into the air by the blower, which can effectively reduce the malodorous components in the gas from the incineration of feces.

[0021] In this utility model, the exhaust gas deodorization device for incineration dry toilets can achieve the purpose of adsorbing the malodorous components in the gas after the odorous gas from the toilet incineration chamber enters the inner part of the outer cylinder through the small through holes on the deodorization unit, thereby effectively reducing the malodorous gas components in the fecal incineration gas.

[0022] In this utility model, the exhaust gas deodorization device for incineration dry toilets, through the mounting frame and bracket, can prevent the multiple filling cylinders of the deodorization unit from shifting when the deodorization unit is installed, thus achieving a fixing effect.

[0023] In this utility model, during use, by installing a blower on the exhaust pipe at one end of the outer cylinder, the gas generated by burning feces will enter the interior of the outer cylinder through the intake pipe, and the odor will be purified by the deodorization unit inside the outer cylinder.

[0024] The deodorization unit can be installed and fixed using mounting brackets and supports, thereby increasing the stability of the device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] Reference Figure 1 An exhaust gas deodorization device for incineration-type dry toilets, applicable in the field of deodorization devices, includes: an outer cylinder 1, an end cap 3, a deodorization unit, and a mounting bracket, etc. An exhaust port is provided on one side of the outer wall of the outer cylinder 1, and an exhaust pipe 4 with a mounting flange ring is connected to facilitate the exhaust gas discharge. An air inlet pipe 2 is fixedly connected to the end of the outer cylinder 1 away from the exhaust port for introducing the exhaust gas generated by the incineration-type dry toilet.

[0032] Specifically, the air inlet pipe 2 at one end of the outer cylinder 1 is connected to the toilet incineration chamber, and the air outlet pipe 4 is connected to the air inlet of the blower. This achieves the overall process of drawing combustion exhaust gas from the toilet into the interior of the outer cylinder 1 through the blower, then through the interior of the deodorization unit, and finally discharging it.

[0033] Reference Figure 3 The end cap 3 is fitted to the end of the outer cylinder 1 away from the intake pipe 2. The side of the end cap 3 near the outer cylinder 1 is provided with a concave surface 12. The inner wall of the concave surface 12 is provided with a threaded groove 13, which is used to fit tightly with one end of the outer cylinder 1 to ensure that the exhaust gas will not leak.

[0034] Reference Figure 2 The deodorization unit is the core part of the device and is located inside the outer cylinder 1. This unit includes five filling cylinders 8. The interior of the cylinders from the air inlet pipe 2 to the end cap 3 is filled with fine sand, activated carbon, precious metal catalyst, biological filler, and activated carbon, respectively. These materials can effectively adsorb and decompose odor components in the exhaust gas to achieve the deodorization effect. Both ends of the filling cylinder 8 are equipped with a breathable mesh, which is only used to prevent the filling material from leaking and to ensure that the exhaust gas can pass through smoothly.

[0035] Specifically, the exhaust gas produced by combustion has a high temperature and contains many particulate impurities. Larger particulate impurities are initially filtered by fine sand, and most of the exhaust gas can be adsorbed by activated carbon through physical adsorption. Precious metal catalysts further remove waste through chemical reactions, and finally, biological filling materials make the exhaust gas removal more complete. Activated carbon can adsorb the harmless gases after conversion. Precious metal catalysts have high catalytic efficiency at 120℃-180℃, while biological filling materials can exert their catalytic activity at 30℃-50℃. The front-end fine sand and activated carbon can significantly reduce the temperature of the exhaust gas, allowing the gas to enter the chemical catalyst and biological active materials at the predetermined temperature.

[0036] The gas in the combustion chamber is drawn in through the air inlet cylinder 1 by a blower, and then enters each deodorization unit through the small through holes on the deodorization unit to adsorb the malodorous components in the gas. The deodorized gas then enters the centrifugal blower through the exhaust port limiting groove 10, and is then discharged into the air by the blower, which can effectively reduce the malodorous gas components in the gas from the incineration of feces.

[0037] Example 2

[0038] refer to Figure 3 An improvement upon Example 1: The mounting bracket, used to install the deodorizing unit, includes a lower half-ring bracket 7 and an upper half-ring bracket 5. The upper half-ring bracket 5 is fixedly mounted on the top of the inner wall of the outer cylinder 1, while the lower half-ring bracket 7 is slidably mounted on the bottom of the inner wall of the outer cylinder 1. This design facilitates the installation and replacement of the deodorizing unit.

[0039] The bracket 6 is used to fix the filling cylinder 8 to ensure its stability during the operation of the device. The bracket 6 is provided with multiple limiting rods 11 on the side near the lower half ring frame 7, and multiple limiting grooves 10 are opened on the lower half ring frame 7. The limiting rods 11 can slide into the limiting grooves 10. Rubber pads 9 are provided between the five adjacent filling cylinders 8 to reduce the possibility of exhaust gas leakage.

[0040] Specifically, when installing the filling cylinder 8 onto the inner wall of the lower half-ring frame 7, multiple filling cylinders 8 are placed through the aforementioned deodorization process, and rubber pads 9 are placed between multiple adjacent filling cylinders 8. Then, the bracket 6 is pushed to move the lower half-ring frame 7 into the inner wall of the outer cylinder 1. After the bracket 6 is moved to the designated position, the end cap 3 is threaded onto one end of the outer cylinder 1. At this time, because rubber pads 9 are placed between multiple filling cylinders 8, the total length of the filling cylinders 8 and rubber pads 9 will be slightly longer than the inner wall of the lower half-ring frame 7, causing it to protrude slightly. When the end cap 3 is reinstalled, the end cap 3 will squeeze the rubber pads 9 between multiple filling cylinders 8 through the bracket 6, causing them to deform to a certain extent, thereby supporting and fixing multiple filling cylinders 8 and increasing stability.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
