Description

Technical Field

[0001] The utility model relates to the field of heat storage incineration devices for treating CO and VOCs flue gas of various industrial furnaces, in particular to an RTO heat storage incineration device which is convenient for dust cleaning and maintenance. Background Art

[0002] As environmental emission requirements become more stringent, enterprises are increasing their efforts to control pollution, and the treatment of CO and VOCs waste gas is becoming more and more important. Therefore, RTO thermal storage incineration devices are increasingly used in related treatment projects.

[0003] At present, RTO thermal storage incineration devices are mainly used to treat organic waste gas and can operate normally and stably for a long time. However, for industrial furnace flue gas with complex components and a certain dust content, especially metallurgical furnace flue gas, the RTO thermal storage incineration device will cause the thermal storage body to be blocked due to the smoke in the flue gas during operation. Once the thermal storage body is blocked, the RTO thermal storage incineration device will not be able to operate normally. In addition, most of the thermal storage bodies on the market are difficult to disassemble and the replacement operation takes a long time, which brings long-term production suspension losses to enterprises.

[0004] The present invention makes new attempts and research and development under such background, and proposes a new idea and system of an RTO thermal storage incineration device which is convenient for dust cleaning and maintenance, so as to solve the above problems. Summary of the invention

At the same time, the utility model can greatly improve the convenience of disassembly and assembly of the easily blocked heat storage body layer in the lower layer of the equipment, thereby ensuring that the disassembly and assembly process does not affect the normal operation of the entire heat storage incineration device, and escorting the normal production of the front-end industrial furnace.

[0043] The RTO thermal storage incineration system 100 includes an RTO thermal storage incineration device body 110, a burner 112 and a thermal storage chamber 120. The thermal storage chamber 120 is arranged in the RTO thermal storage incineration device body 110. The burner 112 is arranged on the top of the RTO thermal storage incineration device body 110. A multi-layer ceramic thermal storage body layer is arranged in the thermal storage chamber 120. The thermal storage body layer includes an upper thermal storage heat exchanger layer 121, a middle thermal storage heat exchanger layer 122 and a lower thermal storage heat exchanger layer 123.

[0044] The RTO thermal storage incineration system 100 provided in this embodiment is further described below:

[0045] Please continue to refer to Figure 1~Figure 2In this embodiment, the RTO thermal storage and incineration system 100 includes an RTO thermal storage and incineration device body 110, a burner 112, a thermal storage chamber 120 and a cylinder chamber 160. The thermal storage chamber 120 is arranged in the RTO thermal storage and incineration device body 110, the burner 112 is arranged on the top of the RTO thermal storage and incineration device body 110, and other auxiliary equipment such as: the explosion-proof port 113 is arranged on the top of the RTO thermal storage and incineration device body 110, and the combustion chamber 114 is arranged in the middle and upper part of the RTO thermal storage and incineration device body 110, above the thermal storage chamber 120. The thermal storage chamber 120 is provided with a multi-layer ceramic thermal storage body layer, and the thermal storage body layer includes an upper thermal storage heat exchanger layer 121, a middle thermal storage heat exchanger layer 122 and a lower thermal storage heat exchanger layer 123, and the cylinder chamber 160 is arranged at the lower part of the thermal storage chamber 120.

[0046] Figure 3 This is a schematic diagram of the basket structure of the lower thermal storage heat exchanger layer 123 of the RTO thermal storage incineration device provided in this embodiment. Figure 1-Figure 2 Optionally, the lower thermal storage heat exchanger layer 123 is arranged at the lower part of the thermal storage chamber 120, and is composed of a basket outer frame 131 and a basket bottom 132. The basket bottom is a screen structure, and a ceramic saddle ring of a heat exchange element is laid in the frame. A plurality of rollers 133 are also arranged at the lower part of the lower thermal storage heat exchanger layer 123. The rollers 133 are fixed by roller fixing devices 134 and slidably cooperate with slide rails 135, so as to facilitate the lower thermal storage heat exchanger layer 123 to be pulled out or installed as a whole from the RTO thermal storage incineration device body 110.

[0047] Each row may have several rollers 133 that are slidably matched with a slide rail 135 at the same time. Optionally, the slide rail 135 is made of angle steel, which has a raised triangular portion, and the roller 133 has a V-shaped groove corresponding to the triangular portion, and the triangular portion is engaged with the V-shaped groove to enable the roller 133 to roll along the slide rail 135. It can be understood that in other embodiments, the number of rollers 133 can also be specifically set according to requirements. It should also be noted that in other embodiments, the shapes of the roller 133 and the first slide rail 135 can also be set according to requirements.

[0048] Furthermore, when the lower thermal storage heat exchanger layer 123 needs to be replaced and repaired, external force can be applied to the basket outer frame 131 to drive the lower thermal storage heat exchanger layer 123 to slide relative to the RTO thermal storage incineration device body 110.

[0049] Figure 4 The schematic diagram of the structure of the roller 133 and the slide rail 135 provided at the lower heat storage heat exchanger layer 123 provided in this embodiment, Figure 5 A schematic structural diagram of the RTO thermal storage incineration system 100 provided in this embodiment at a second viewing angle. Figure 6This is a schematic diagram of the connection of the RTO cylinder chamber and related pipeline valves provided in this embodiment. Figure 1-Figure 6 In this embodiment, the flue gas inlet 141 and the flue gas exhaust port 166 are distributed on both sides of the cylinder chamber 160 below the regenerator 120, and are respectively connected to the inlet flue 142 and the outlet flue 143. The original flue gas enters the cylinder chamber 160 through the inlet flue 142 and the flue gas inlet 141, and then enters the regenerator 120 for heat exchange, and then undergoes high-temperature combustion reaction in the combustion chamber 114. Then, part of the treated flue gas passes through the heat storage layer for heat exchange and leaves the RTO thermal incineration device body 110 through the outlet flue 143, and the other part passes through the furnace hot air outlet pipe 145 on the upper part of the RTO thermal incineration device body 110, and finally enters the post-processing flue gas pipe 147 after mixing with another flue gas in the air mixing box 146, and is sent to the subsequent flue gas treatment facilities.

[0050] Figure 6 The schematic diagram of the connection of the RTO cylinder chamber and related pipeline valves provided in this embodiment shows that the smoke exhaust port 166 is connected to the outlet pipe 143, and the outlet pipe 143 is provided with an exhaust valve 167. The purge air port 163 is connected to the purge air duct 165, and the purge air valve 164 is provided on the purge air duct 165. A purge fan 171 is installed at the front end of the purge air duct 165. The opening and closing states of the lifting valve 161, the air intake valve 162, the purge air door 163, and the purge air valve 164 are controlled by an automated program to realize the air intake, exhaust, and purge actions, respectively.

[0051] In this embodiment, the lower thermal storage heat exchanger layer 123 can be designed according to the width of the RTO thermal storage incineration device body 110. If the width is large, considering the load-bearing problem after the lower thermal storage heat exchanger layer 123 is filled with the thermal storage original ceramic saddle ring, it can be divided into several parts and placed on the slide rail 135 in sequence. The number of slide rails 135 can also be increased to reduce the gap between the slide rails. The basket outer frame 131 between several lower thermal storage heat exchanger layer 123 modules is connected by hooks or the like (not shown in the figure). When the lower thermal storage heat exchanger layer 123 needs to be replaced and repaired, an external force can be applied to the basket outer frame 131 to drive the lower thermal storage heat exchanger layer 123 modules to slide relative to the RTO thermal storage incineration device body 110 in sequence, and take them out one by one through the lower inspection port 152. Similarly, when installing the lower thermal storage heat exchanger layer 123 modules back, they are also installed one by one back into the RTO thermal storage incineration device body 110.

[0052] Furthermore, in the present embodiment, when a multi-module lower heat storage heat exchanger layer 123 is adopted, the sealing between the modules is taken into consideration, and it is mainly considered that the flue gas must pass through the saddle rings of the heat storage modules in the lower heat storage heat exchanger layer 123 for heat exchange, and at the same time, the saddle rings are used to intercept a small amount of smoke in the flue gas so that it does not affect and block the middle heat storage heat exchanger layer 122. The appearance of the basket outer frame 131 can be square or beveled, and the two modules are directly matched through the bevel to achieve a natural sealing function, further reducing the gap, so that the flue gas can completely pass through the gap between the saddle rings of the heat storage modules in the lower heat storage heat exchanger layer 123, thereby ensuring the effects of heat exchange and smoke interception.

[0053] According to the RTO thermal storage incineration system 100 provided in this embodiment, which is convenient for cleaning and maintenance, the working principle of the RTO thermal storage incineration system 100 is as follows:

[0054] During use, the original flue gas enters the heat storage layer through the inlet flue 142 and the flue gas inlet 141 for heat exchange, and passes through the lower heat storage heat exchanger layer 123, the middle heat storage heat exchanger layer 122 and the upper heat storage heat exchanger layer 121 in turn. A small amount of smoke carried in the flue gas will be intercepted in the lower heat storage heat exchanger layer 123, mainly attached to the filler ceramic saddle ring, and then the flue gas passes through the high-temperature combustion reaction in the combustion chamber 114 to achieve effective removal of CO and VOCs. Then, a part of the treated flue gas passes through the heat storage layer and then the heat storage layer, and then leaves the RTO heat storage incineration device body 110 through the outlet flue 143, and the other part passes through the furnace hot air outlet pipe 145 on the upper part of the RTO heat storage incineration device body 110, and finally mixes with another flue gas in the air mixing box 146 and enters the post-treatment flue gas pipe 147, and is sent to the subsequent flue gas treatment facilities.

[0055] The RTO thermal storage incineration system 100 provided in this embodiment and convenient for cleaning and maintenance has at least the following advantages:

[0056] An embodiment of the utility model provides an RTO thermal storage incineration system 100 which is easy to clean and maintain, wherein a plurality of ceramic thermal storage layers are arranged in a thermal storage chamber 120 of the RTO thermal storage incineration system 100, including an upper thermal storage heat exchanger layer 121, a middle thermal storage heat exchanger layer 122 and a lower thermal storage heat exchanger layer 123. The basket structure design of the lower heat storage heat exchanger layer 123 of the RTO heat storage incineration device has a screen structure at the bottom 132 of the basket, and a heat storage module ceramic saddle ring is laid in the frame. The heat storage module ceramic saddle ring in the lower heat storage heat exchanger layer 123 can not only perform heat exchange, but also use the saddle ring to intercept a small amount of smoke in the flue gas, purify the flue gas, so that it does not affect and block the middle heat storage heat exchanger layer 122 and the upper heat storage heat exchanger layer 121, and then a plurality of rollers 133 and slide rails 135 are also provided at the bottom of the lower heat storage heat exchanger layer 123 to facilitate the sliding cooperation of the lower heat storage heat exchanger layer 123 as a whole. It can be pulled out or installed from the RTO thermal storage incineration device body 110 through the lower inspection port 152. The entire replacement operation process can be controlled automatically. After cutting off the air intake, the entire lower thermal storage heat exchanger layer 123 of the single thermal storage chamber 120 can be quickly replaced after a short period of ventilation and cooling. The lower thermal storage heat exchanger layer 123 of the entire RTO thermal storage incineration system 100 can be replaced quickly and conveniently through the same processing method, so that the RTO thermal storage incineration system 100 can be restored to its optimal performance. The process is convenient and efficient, and there is no need to shut down the system for replacement, which effectively guarantees the normal production of the front-end industrial furnace.
