Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an RTO waste gas treatment device that can recover thermal energy. Background Technology

[0002] RTO (Regenerative Thermal Oxidizer) is a highly efficient organic waste gas treatment device. Compared with traditional catalytic combustion and direct-fired thermal oxidizers (TO), it has the advantages of high thermal efficiency (≥95%), low operating cost, and the ability to treat large volumes of low-concentration waste gas. When the concentration is slightly higher, secondary waste heat recovery can also be performed, which greatly reduces production and operating costs.

[0003] Application number CN202123301860.3 discloses an energy-saving RTO waste gas treatment device, including a purification tank and a scrubbing tank. In this invention, the decomposition tank rotates above a partition, ensuring the ceramic heat storage plate is always positioned below the combustion and preheating decomposition chambers. This allows the heat generated by combustion in the combustion chamber to be directly transferred to the interior of the preheating chamber for preheating the organic waste gas, resulting in greater energy savings and effectively reducing the device's footprint. However, in practical applications, this application has been found to have limited preheating effect on the organic waste gas, making it difficult to stably reach the preset calibration value. This insufficient preheating leads to the downstream decomposition stage still consuming a large amount of additional energy, resulting in relatively high overall operating power consumption. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A heat recovery RTO waste gas treatment device includes a regeneration mechanism and a stabilization mechanism. The regeneration mechanism includes a three-chamber RTO incinerator, a sleeve located at the front of the three-chamber RTO incinerator, a ceramic heat storage cylinder located inside the sleeve, three heat-conducting metal plates extending through the rear wall of the sleeve and fixed between the three-chamber RTO incinerator and the ceramic heat storage cylinder, a pipe body connected to one end of the sleeve, and a branch pipe located at the bottom of the sleeve and connected between the three-chamber RTO incinerator and the pipe body. The stabilization mechanism includes a branch pipe extending through the top of the sleeve, a connecting pipe connecting the pipe body and the branch pipe, and a low-pressure reducing valve and a high-pressure reducing valve extending through the top of the branch pipe.

[0007] By adopting the above technical solution, when the three-chamber RTO incinerator is running, the heat generated is transferred to the ceramic heat storage cylinder through the heat-conducting metal plate. The ceramic heat storage cylinder heats the inside of the tube sleeve to prepare for preheating the waste gas. Then, the waste gas is introduced through the inlet pipe and flows through the first chamber, the preheating chamber and the second chamber in sequence. When the waste gas enters the preheating chamber, the flow rate is greatly reduced and the path is increased. Then, the waste gas has enough time to rise to the rated temperature. The preheated waste gas then enters the three-chamber RTO incinerator through the pipe body and the diversion pipe, thereby reducing its power consumption.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the regeneration mechanism further includes a first chamber, a preheating chamber, and a second chamber, all of which are located inside the sleeve; the ceramic heat storage cylinder body extends laterally through the preheating chamber; the two ends of the ceramic heat storage cylinder extend into the interiors of the first and second chambers, respectively; and the first, preheating, and second chambers are connected in pairs.

[0009] In a preferred embodiment, the present invention can be further configured such that the branch pipe is located at the top of the bucket cavity and communicates with the interior of the bucket cavity.

[0010] In a preferred embodiment, the present invention can be further configured such that: the second hopper is connected to the interior of the three-chamber RTO incinerator through a pipe body and a diversion pipe, and the pipe sleeve, pipe body, and diversion pipe are all made of heat-insulating material.

[0011] In a preferred embodiment, the present invention can be further configured such that: an air inlet pipe is installed at the other end of the sleeve, and the air inlet pipe is connected to the interior of the bucket cavity.

[0012] In a preferred embodiment, the present invention can be further configured such that: a one-way valve is provided at the top of the pipe body, and the one-way valve is installed on the connecting pipe.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the three-chamber RTO incinerator is running, the heat generated is transferred to the ceramic heat storage cylinder through the heat-conducting metal plate. The ceramic heat storage cylinder heats the inside of the tube sleeve to prepare for preheating the waste gas. Then, the waste gas is introduced through the inlet pipe and flows through the first chamber, the preheating chamber and the second chamber in sequence. When the waste gas enters the preheating chamber, the flow rate is greatly reduced and the path is increased. Then, the waste gas has sufficient time to rise to the rated temperature. Then, the preheated waste gas enters the three-chamber RTO incinerator through the pipe body and the diversion pipe, thereby reducing its power consumption.

[0015] 2. In this utility model, when the air flow rate inside the first hopper is large, the low-pressure reducing valve and the high-pressure reducing valve work together to release the excess air flow inside the first hopper. This part of the air flow enters the diversion pipe through the connecting pipe and the pipe body, thereby maintaining the stability of the exhaust gas preheating operation inside the pipe sleeve.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an RTO waste gas treatment device capable of recovering thermal energy.

[0029] Example 1:

[0030] Combination Figure 1-5As shown, the present invention provides an RTO waste gas treatment device with recoverable heat energy, including a heat recovery mechanism 100 and a stabilization mechanism 200. The heat recovery mechanism 100 includes a three-chamber RTO incinerator 110, a sleeve 140 disposed on the front side of the three-chamber RTO incinerator 110, a ceramic heat storage cylinder 130 disposed inside the sleeve 140, three heat-conducting metal plates 120 with their bodies penetrating through the rear side wall of the sleeve 140 and fixed between the three-chamber RTO incinerator 110 and the ceramic heat storage cylinder 130, a pipe body 150 connected to one end of the sleeve 140, and a diversion pipe 160 disposed at the bottom of the sleeve 140 and connected between the three-chamber RTO incinerator 110 and the pipe body 150.

[0031] The stabilization mechanism 200 includes a branch pipe 210 passing through the top of the sleeve 140, a connecting pipe 220 connecting the pipe body 150 and the branch pipe 210, a low-pressure reducing valve 230 passing through the top of the branch pipe 210, and a high-pressure reducing valve 240.

[0032] Specifically, the regeneration mechanism 100 also includes a first hopper 170, a preheating chamber 180, and a second hopper 190, all of which are located inside the sleeve 140. The ceramic heat storage cylinder 130 extends laterally through the preheating chamber 180, and its two ends extend into the first hopper 170 and the second hopper 190, respectively. The first hopper 170, the preheating chamber 180, and the second hopper 190 are connected in pairs. This structural design provides conditions for reducing the exhaust gas flow rate and also provides sufficient time for exhaust gas preheating.

[0033] Furthermore, the branch pipe 210 is located at the top of the hopper cavity 170 and communicates with the inside of the hopper cavity 170. The layout design of the branch pipe 210 effectively dissipates excess waste gas inside the hopper cavity 170.

[0034] Furthermore, the second chamber 190 is connected to the interior of the three-chamber RTO incinerator 110 through the pipe body 150 and the diversion pipe 160. The pipe sleeve 140, the pipe body 150, and the diversion pipe 160 are all made of heat-insulating material. Using heat-insulating material to make the three can prevent workers from being burned when they accidentally touch them.

[0035] Example 2:

[0036] Combination Figure 1-3 and Figure 5 As shown, based on Embodiment 1, an air inlet pipe 300 is installed at the other end of the sleeve 140. The air inlet pipe 300 is connected to the inside of the bucket cavity 170. The air inlet pipe 300 is provided to provide conditions for injecting waste gas into the bucket cavity 170.

[0037] Example 3:

[0038] Combination Figure 1, 2 and Figure 5 As shown, in the above embodiment, a one-way valve 400 is provided at the top of the pipe body 150. The one-way valve 400 is installed on the connecting pipe 220. The one-way valve 400 can prevent the exhaust gas in the pipe body 150 from entering the interior of the connecting pipe 220.

[0039] The working principle and usage process of this utility model: When the three-chamber RTO incinerator 110 is running, the heat generated is transferred to the ceramic heat storage cylinder 130 through the heat-conducting metal plate 120. The ceramic heat storage cylinder 130 heats the inside of the sleeve 140 to prepare for preheating the waste gas. Then, the waste gas is introduced through the inlet pipe 300. The waste gas flows through the first chamber 170, the preheating chamber 180 and the second chamber 190 in sequence. When the waste gas enters the preheating chamber 180, the flow rate is greatly reduced and the path is increased. Then, the waste gas has enough time to rise to the set temperature. Then, the preheated waste gas enters the three-chamber RTO incinerator 110 through the pipe body 150 and the diversion pipe 160, thereby reducing its power consumption.

[0040] During this period, when the air flow rate inside the bucket cavity 170 is large, the low-pressure reducing valve 230 and the high-pressure reducing valve 240 work together to release the excess air flow inside the bucket cavity 170. This part of the air flow enters the diversion pipe 160 through the connecting pipe 220 and the pipe body 150, thereby maintaining the stability of the exhaust gas preheating operation inside the sleeve 140.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
