Description

Technical Field

[0001] The present invention discloses the technical field of gas combustion furnaces, and in particular relates to a heat recovery device for an RTO waste gas combustion furnace. Background Art

[0002] RTO waste gas treatment equipment is an effective organic waste gas treatment equipment. Its principle is to convert organic matter in waste gas into corresponding carbon dioxide and water at high temperature, thereby purifying waste gas and recovering the heat released when waste gas is decomposed. The three-chamber RTO waste gas decomposition efficiency reaches more than 99%, and the heat recovery efficiency reaches more than 95%. It has the characteristics of low operating cost and can handle low-concentration waste gas with large air volume. When the concentration is slightly higher, secondary waste heat recovery can be performed, which greatly reduces production and operation costs.

[0003] After searching the publication (announcement) number: CN212408690U, a low-energy RTO combustion furnace is disclosed, which relates to the field of gas combustion furnaces, including a waste gas pipeline for transmitting organic waste gas, a combustion chamber for gas combustion, a preheating chamber for preheating the organic waste gas in the waste gas pipeline using the hot waste gas generated in the combustion chamber, and a heat exchange chamber for recovering the heat in the hot waste gas... This application has the advantages of using the heat of organic waste gas combustion to preheat the organic waste gas, and the preheating effect is better, so as to realize the recycling of waste gas heat. This application allows the high-temperature gas generated after combustion to first enter the preheating chamber to heat the preheating pipeline, and then enter the heat exchange chamber, where the heat is taken away by cooling oil and cooling water. After the temperature is lowered, it enters the filter chamber and passes through the activated carbon adsorption layer for secondary filtration. However, after the activated carbon adsorption layer has been used for a period of time, it is necessary to shut down regularly to disassemble, clean or replace the activated carbon adsorption layer, which leads to the inability to filter continuously, greatly reducing the work efficiency.

[0004] In summary, how to achieve the purpose of conveniently disassembling, cleaning or replacing the activated carbon adsorption layer without stopping the machine, thereby improving work efficiency, is a technical problem that needs to be solved urgently. To this end, we propose a heat recovery device for RTO waste gas combustion furnace. Utility Model Content

[0019] As mentioned in the background technology, in the prior art, after the activated carbon adsorption layer has been used for a period of time, it is necessary to regularly shut down the machine to disassemble, clean or replace the activated carbon adsorption layer, which results in failure of continuous filtration and greatly reduces the working efficiency.

[0020] Example:

[0021] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution, a heat recovery device for an RTO waste gas combustion furnace, including a waste gas heat recovery mechanism 1, the waste gas heat recovery mechanism 1 belongs to the prior art, and its structure and working principle are all referred to a low-energy RTO combustion furnace with a publication (announcement) number of CN212408690U, which will not be repeated herein, the right end of the waste gas heat recovery mechanism 1 is connected with a connecting pipe 2, the connecting pipe 2 is arranged in a "U" shape, both ends of the connecting pipe 2 are connected with a filter chamber 3, the middle of the filter chamber 3 is fixedly connected with a partition 10, the partition 10 divides the filter chamber 3 into two filter spaces, so that the activated carbon adsorption layer 6 in the two filter spaces can be used in turn, the two ends of the connecting pipe 2 are respectively connected with the two filter spaces, the partition 10 and the filter chamber 3 are integrally formed, the front and rear end surfaces of the filter chamber 3 are provided with slots 11, and the front and rear sides of the filter chamber 3 are slidably connected with a frame 7;

[0022] Two groups of activated carbon adsorption layers 6 are detachably connected inside the frame 7. When one of the activated carbon adsorption layers 6 needs to be disassembled, cleaned or replaced, the valve 9 corresponding to the left side of the other activated carbon adsorption layer 6 is opened, and then the valve 9 corresponding to the left side of the activated carbon adsorption layer 6 that needs to be replaced is closed, so that the other activated carbon adsorption layer 6 is used for adsorption, and then the staff will disassemble and replace the activated carbon adsorption layer 6 that needs to be replaced, thereby achieving non-stop operation while conveniently disassembling, cleaning or replacing the activated carbon adsorption layer 6, achieving continuous filtration and improving work efficiency. Two exhaust pipes 4 are symmetrically fixedly connected to the upper side of the right end surface of the filter chamber 3, two valves 9 are symmetrically installed on the connecting pipe 2, and two pushing assemblies are symmetrically arranged on the right end surface of the filter chamber 3. The two groups of frames 7 are respectively arranged on the front and rear sides of the partition 10, and the opposite sides of the two groups of frames 7 extend to the inside of the slot 11.

[0023] See also Figure 3 The inner wall of the filter chamber 3 is symmetrically provided with limiting slots 5 for limiting the frame 7, and the limiting slots 5 extend to the surface of the filter chamber 3 away from the side of the partition 10. The limiting slots 5 can support and limit the left and right sides of the frame 7, thereby improving the stability of the frame 7 installed inside the filter chamber 3.

[0024] See also Figure 2 and Figure 3 The pushing component includes an electric push rod 13, and the right end surface of the filter chamber 3 is symmetrically fixedly connected with the electric push rod 13, and the output end of the electric push rod 13 is fixedly connected with a fixing plate 12, and the inner surface of the fixing plate 12 is in the same horizontal plane as the surface of the frame 7, and the inner surface of the fixing plate 12 is fixedly connected to the surface of the frame 7 away from the electric push rod 13. The electric push rod 13 is controlled to extend to drive the fixing plate 12 to move, and the movement of the fixing plate 12 drives the frame 7 to move, so that the side of the activated carbon adsorption layer 6 close to the partition 10 is moved out to the outside of the filter chamber 3 and the movement can be stopped to prevent the frame 7 from falling from the filter chamber 3. In this way, the side of the activated carbon adsorption layer 6 close to the partition 10 is moved out to the outside of the filter chamber 3, which is convenient for removing the activated carbon adsorption layer 6, and the filter chamber 3 will not hinder the movement of the activated carbon adsorption layer 6. At the same time, the inner bottom wall of the notch 11 is used to support the side wall of the frame 7 close to the partition 10.

Both ends of the limiting plate 14 extend to the inside of the limiting hole 8. Two limiting grooves 15 matched with the limiting plate 14 are symmetrically opened on the outside of the activated carbon adsorption layer 6. The cooperation of the limiting groove 15 and the limiting plate 14 can further limit the activated carbon adsorption layer 6. When it is necessary to remove the activated carbon adsorption layer 6, it is directly pushed from one side of the activated carbon adsorption layer 6, and the activated carbon adsorption layer 6 moves on the outside of the limiting plate 14, so as to facilitate the activated carbon adsorption layer 6 to be moved out of the interior of the frame 7, so that the activated carbon adsorption layer 6 can be simply and quickly removed.

[0026] Working principle: when one of the activated carbon adsorption layers 6 needs to be disassembled, cleaned or replaced, the valve 9 corresponding to the left side of the other activated carbon adsorption layer 6 is opened, and then the valve 9 corresponding to the left side of the activated carbon adsorption layer 6 to be replaced is closed, so that the other activated carbon adsorption layer 6 is used for adsorption, and then the staff disassembles and replaces the activated carbon adsorption layer 6 to be replaced. First, the electric push rod 13 is controlled to extend to drive the fixed plate 12 to move, and the movement of the fixed plate 12 drives the frame 7 to move, so that the side of the activated carbon adsorption layer 6 close to the partition 10 is moved out to the outside of the filter chamber 3 and then it can stop. Move, and then push directly from one side of the activated carbon adsorption layer 6, the activated carbon adsorption layer 6 moves on the outside of the limiting plate 14, so as to facilitate the activated carbon adsorption layer 6 to be moved out of the interior of the frame 7, so that the activated carbon adsorption layer 6 can be simply and quickly disassembled for cleaning or replacement, so as to achieve non-stop while also being able to conveniently disassemble, clean or replace the activated carbon adsorption layer 6, to achieve continuous filtration and improve work efficiency; when the activated carbon adsorption layer 6 in use needs to be disassembled, cleaned or replaced next time, the same operation can be used, so that the activated carbon adsorption layers 6 inside the two groups of frames 7 can be used in turn.
