Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas treatment technology, and specifically relates to a device for the harmless incineration of production gas exhaust gas. Background Technology

[0002] The methanol-to-hydrogen process generates tail gas containing harmful substances such as carbon monoxide and carbon dioxide. To reduce the environmental impact of these pollutants, tail gas incineration and harmless treatment devices are typically used. These devices convert harmful gases into relatively harmless water vapor and carbon dioxide through high-temperature incineration, ensuring emissions meet environmental standards. However, existing tail gas incineration and harmless treatment devices often contain a certain amount of solid particulate matter, which may originate from unreacted catalysts, coke, etc. If these particles are not treated, they can clog internal pipes, affecting the normal incineration operation. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for the harmless incineration of production gas tail gas, and to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a production gas tail gas incineration harmless treatment device, comprising: an incineration device body and an impurity filter assembly, wherein an impurity filter assembly for filtering tail gas impurities is installed on the front side of the incineration device body.

[0005] The impurity filtration assembly includes a quick-release cap for screwing onto the tube body. Inside the tube body, at the front, there is a retaining ring for installing a filter bag. A top ring is installed above the retaining ring, and the top ring and the filter bag are an integral structure.

[0006] In a preferred embodiment, the incineration device has an air inlet on the front side of its main body, which is connected and fixed to the rear side of the impurity filter assembly. The quick-release cover has a connection interface on its front side, which is threadedly connected to an external gas supply pipe.

[0007] In a preferred embodiment, the quick-release cover has a screw ring on the back and a screw groove is provided on the inner side of the front of the tube body. The screw groove matches the specifications of the screw ring. The quick-release cover is threadedly connected to the inner side of the front of the tube body, so that the quick-release cover can be quickly removed, which facilitates the removal of the top ring and the filter bag, and thus facilitates the maintenance of the filter bag.

[0008] In a preferred embodiment, the radius of the swivel ring matches the radius of the inner side of the front of the tube body, a retaining ring is integrally formed below the swivel groove, and mounting holes are provided at the four corners of the top of the retaining ring.

[0009] In a preferred embodiment, the radius of the retaining ring matches the radius of the top ring, and the top of the top ring has four mounting holes of the same specifications as mounting hole two at its four corners. A bolt is screwed into mounting hole two, and both mounting hole two and mounting hole one are matched with the specifications of the bolt.

[0010] In a preferred embodiment, the radius of the top of the filter bag is smaller than the radius of the top ring, and the mesh diameter of the filter bag is smaller than the diameter of the particulate impurities.

[0011] In a preferred embodiment, an impact ring is installed below the filter bag, and the left side of the impact ring is connected to a drive motor below the filter bag via a coupling.

[0012] In a preferred embodiment, the drive motor is mounted on a mounting bracket above the lower side of the inner side of the tube. The outer side of the mounting bracket is welded and fixed to the inner wall of the tube. The rear side of the tube is fixed to the inner side of the tube by a threaded connection. The mounting bracket is fixed inside the rear side of the tube. The drive motor is mounted on the mounting bracket. The drive motor drives the striking ring to strike and vibrate the filter bag, thereby preventing impurities from clogging the mesh in the upper area of ​​the filter bag.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting an impurity filtration assembly, which includes a pipe body, a quick-release cover, and a filter bag, the rear side of the pipe body is connected and fixed to the air inlet. The quick-release cover is connected to the external gas supply pipe via a threaded connection through a mating interface. The top ring is connected and fixed by four sets of bolts and retaining rings, thereby installing the filter bag inside the pipe body. The advantage of this installation method is that it facilitates quick disassembly and assembly of the impurity filtration assembly, thus facilitating maintenance and cleaning. By setting a striking ring, after the exhaust gas enters the pipe body, it is filtered by the filter bag, trapping particulate impurities inside the mesh of the filter bag. After long-term use, the mesh of the filter bag is easily clogged. The striking ring can strike the filter bag to prevent the mesh from clogging. Therefore, the final effect is that by setting an impurity filtration assembly, particulate impurities in the exhaust gas can be effectively intercepted, thereby preventing these impurities from clogging the pipe and affecting the normal operation of the main body of the incineration device.

[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 one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 3 A device for harmless incineration of production gas tail gas includes: an incineration device body 100 and an impurity filter assembly 200, wherein the impurity filter assembly 200 for filtering impurities in the tail gas is installed on the front side of the incineration device body 100.

[0024] The impurity filtration assembly 200 includes a quick-release cap 210 for screwing onto the tube body 220. Inside the tube body 220, at the front, there is a retaining ring 230 for installing a filter bag 310. A top ring 300 is installed above the retaining ring 230. The top ring 300 and the filter bag 310 are an integral structure.

[0025] The main body 100 of the incineration device has an air inlet 110 on the front side, which is connected and fixed to the rear side of the impurity filter assembly 200. The quick-release cover 210 has a connection interface 211 on the front side, which is threaded to the external gas supply pipe.

[0026] The quick-release cover 210 has a screw ring 212 on the back, and the tube body 220 has a screw groove 221 on the inner side of the front. The screw groove 221 matches the specifications of the screw ring 212. The quick-release cover 210 is threadedly connected to the inner side of the front of the tube body 220, so that the quick-release cover 210 can be quickly removed, and then the top ring 300 and the filter bag 310 can be easily removed, which facilitates the maintenance of the filter bag 310.

[0027] The radius of the swivel ring 212 matches the radius of the inner side of the front of the tube body 220. A retaining ring 230 is integrally formed below the swivel groove 221, and mounting holes 231 are provided at the four corners of the top of the retaining ring 230.

[0028] The radius of the retaining ring 230 matches the radius of the top ring 300. The top four corners of the top ring 300 are provided with mounting holes 301 of the same specifications as mounting holes 231. Bolts 320 are screwed into the mounting holes 231. Both mounting holes 231 and mounting holes 301 match the specifications of bolts 320.

[0029] The radius of the top of the filter bag 310 is less than the radius of the top ring 300, and the mesh diameter of the filter bag 310 is less than the diameter of the particulate impurities.

[0030] A striking ring 400 is installed below the filter bag 310. The left side of the striking ring 400 is connected to the drive motor below the filter bag 310 via a coupling.

[0031] The drive motor is installed above the mounting bracket on the lower inner side of the tube body 220. The outer side of the mounting bracket is welded and fixed to the inner wall of the tube body 220. The rear side of the tube body 220 is fixed to the tube body 220 by a threaded connection. The mounting bracket is fixed inside the rear side of the tube body 220. The drive motor is installed on the mounting bracket. The drive motor drives the striking ring 400 to strike and vibrate the filter bag 310, thereby preventing impurities from clogging the mesh in the upper area of ​​the filter bag 310.

[0032] Example 1: Please refer to Figures 1 to 3In actual use, the external gas supply pipe delivers the exhaust gas generated during the operation of the methanol-to-hydrogen unit to the impurity filter assembly 200 through the interface 211. After the exhaust gas passes through the quick-release cover 210 and enters the pipe body 220, it passes through the filter bag 310 and enters the incineration unit body 100 through the air inlet 110. Finally, it is incinerated by the incineration unit body 100 for harmless treatment (the incineration unit body 100 is existing technology, and its internal structure and working principle will not be described here). During the process of the exhaust gas passing through the filter bag 310, the particulate impurities contained in the exhaust gas due to incomplete reaction are blocked by the mesh of the filter bag 310. These impurities are blocked inside the filter bag 310, thereby preventing impurities from entering the incineration unit body 100 through the air inlet 110 and clogging the pipes, thus affecting the normal use of the incineration unit body 100.

[0033] After prolonged use, impurities will gradually accumulate in the filter bag 310 and clog the mesh. If not addressed promptly, this can reduce the filtration efficiency of the filter bag 310. In this case, the drive motor mounted on the top of the mounting bracket inside the tube body 220 can be periodically activated. After the drive motor starts operating, it drives the striking ring 400 below the filter bag 310 to rotate from front to back via a coupling. Since the striking ring 400 is located below the filter bag 310, it is horizontal when stationary. When rotating, the striking ring 400 continuously strikes the filter bag 310, thereby vibrating and dislodging impurities inside the mesh of the filter bag 310 to the bottom of the filter bag 310. This ensures the unobstructed flow of the mesh in the upper area of ​​the filter bag 310, allowing the exhaust gas to pass smoothly through the filter bag 310 and thus ensuring the filtration effect of the filter bag 310. Ultimately, by setting up the impurity filtration component 200, impurities in the exhaust gas can be prevented from entering the incineration unit body 100, thus preventing impurities from clogging the pipes.

[0034] Example 2: Please refer to Figure 2 and Figure 3 After prolonged use, the impurity filter assembly 200 requires maintenance. First, rotate the interface 211 in the opposite direction to disconnect it from the external air supply pipe. Then, grasp the quick-release cover 210 and rotate it in the opposite direction to remove it, exposing the front of the tube body 220. Next, use a screwdriver to remove the four sets of bolts 320. Then, use a hook to hook the two sets of hooks on the top of the top ring 300 and pull upwards to remove the filter bag 310 from inside the tube body 220. The filter bag 310 can then be rinsed and cleaned. After cleaning, the filter bag 310 can be reinstalled inside the tube body 220 following the same steps. Finally, screw the quick-release cover 210 back onto the tube body 220 to complete the maintenance of the impurity filter assembly 200. The ultimate goal is to facilitate the maintenance of the filter bag 310.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
