[0002] When treating waste liquid containing alkynes, incinerating with an incinerator is one of the commonly used means of environmental protection. There are two types of incinerators in total. One is a regenerative thermal oxidizer (RTO) that conducts high-temperature oxidation decomposition, and the other is a regenerative catalytic oxidizer (RCO) that conducts catalytic oxidation decomposition. The former uses a high-temperature environment to oxidize and decompose hydrocarbons, that is, to burn them into water and carbon dioxide, while the latter adds a catalyst to the heat storage body in the furnace according to the incinerated material, and uses the catalyst to increase the activity of the incinerated material, thereby reducing the temperature required for its oxidation and decomposition. As described in a three-chamber RTO regenerator incinerator disclosed in the patent number: CN219550541, the general structure of the incinerator is recorded, that is, multiple combustion chambers are installed above the furnace chamber. In each combustion chamber of the incinerator, the waste liquid is incinerated to form water and carbon dioxide. To ensure the smooth progress of the maintenance process, it is necessary to add access holes for maintenance personnel on the walls of the combustion chamber. During the furnace shutdown period, the inside of the chamber can be observed and maintained through the access holes. However, due to the excessively high temperature inside the combustion chamber, the position where the door frame and the door panel contact is prone to deformation, resulting in an increase in the intensity of the door panel being squeezed and an increase in the difficulty of opening the door panel. Summary of the Utility Model

A door panel device is installed on the heat storage chamber. The door panel device includes a door frame embedded and fixed on the side wall of the heat storage chamber, a door panel hinged on the door frame, and a pushing wedge block arranged between the door frame and the door panel. A sliding groove is opened on the side surface of the door panel, the bottom of the sliding groove is in an inclined state, one end of the sliding groove is arranged close to the inner side of the door panel, and the other end of the sliding groove is arranged far from the inner side of the door panel. The thickness of the pushing wedge block is greater than the maximum depth of the sliding groove, and the pushing wedge block can be slidably received in the sliding groove.

[0005] Further, a bearing platform for bearing the door panel is convexly arranged inward in the door frame, and the door panel is placed on the bearing platform after rotating around the edge of the door frame.

[0006] Further, a helping sliding groove is formed on the groove wall of the sliding groove, a limiting post is installed on the side wall of the pushing wedge block, and the limiting post is slidably inserted into the helping sliding groove.

[0007] Further, a limiting groove is further formed at the bottom of the sliding groove, the limiting groove penetrates through the door panel, a limiting frame is inserted into the pushing wedge block in a pluggable manner, and the limiting frame extends out of the door panel through the limiting groove.

[0008] Further, a connecting hole is formed in the pushing wedge block, and the limiting frame is inserted into the connecting hole in a pluggable manner.

[0009] Further, insertion slots are respectively formed on both sides of the sliding groove on the edge of the door panel.

Specific implementation mode

[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and scope of the appended claims.

[0022] As Figure 1 shown, this embodiment provides a regenerative waste liquid incinerator, including a furnace body 10, a pipeline device 20 installed on the furnace body 10, and a plurality of heat storage chambers 30 arranged on the furnace body 10.

[0023] The furnace body 10 is installed below the heat storage chamber 30, the pipeline device 20 is installed inside the furnace body 10, and the pipeline device 20 can inject high-temperature gas into the furnace body 10. Then, the furnace body 10 injects high-temperature gas into a plurality of heat storage chambers 30. Under the heating of the high-temperature gas, the heat storage chamber 30 maintains a temperature capable of oxidizing and decomposing the waste liquid. The waste liquid is oxidized and decomposed into harmless gases such as water and carbon dioxide in the oxygen-rich and high-temperature environment of the heat storage chamber 30, completing the treatment of the waste liquid.

[0024] The furnace body 10 has a funnel-shaped structure, and the heat storage chamber 30 is installed at the large-end opening of the furnace body 10. The furnace body 10 communicates with the inside of the heat storage chamber 30. A heat storage body 310 is arranged inside the heat storage chamber 30. The heat transfer efficiency of the heat storage body 310 is reduced, and the heat storage body 310 can maintain a high-temperature environment inside the heat storage chamber 30. High-temperature gas can be input from the small end of the furnace body 10, and the high-temperature gas heats the heat storage body 310.

[0025] As Figures 1 to 6 shown, a door panel device 320 is installed on the heat storage chamber 30. The door panel device 320 includes a door frame 321 embedded and fixed on the side wall of the heat storage chamber 30, a door panel 322 hinged to the door frame 321, and a pushing wedge 323 arranged between the door frame 321 and the door panel 322.

[0026] As Figures 1 to 3As shown, the door frame 321 is clamped on the door hole of the heat storage chamber 30. The door panel 322 is hinged within the door frame 321. The interior of the door frame 321 is configured corresponding to the outer shape of the door panel 322. After the door panel 322 rotates within the door frame 321, it can be inlaid on the side of the door frame 321. Sealing rubber strips are covered on the edges of both the door panel 322 and the door frame 321. Under the sealing of the sealing rubber strips, the sealing performance of the door panel device 20 is improved, enabling the temperature inside the heat storage chamber 30 to always be maintained at a specified level. The door frame 321 is convexly provided with a bearing platform 340 for bearing the door panel 322. After the door panel 322 rotates around the edge of the door frame 321, it is placed on the bearing platform 340.

[0027] As Figures 3 to 6 shown, a sliding groove 324 is formed in the door panel 322. The sliding groove 324 is formed on the side wall and the inner wall of the door panel 322. The notch of the sliding groove 324 is arranged corresponding to the bearing platform 340 of the door frame 321. The bottom of the sliding groove 324 is in an inclined state. Specifically, one end of the bottom of the sliding groove 324 is close to the inner side of the door panel 322, and the other end of the bottom of the sliding groove 324 is far from the inner side of the door panel 322. The sliding groove 324 communicates with the inner side and the side wall of the door panel 322. A guiding groove 325 is formed on the groove wall of the sliding groove 324. The guiding groove 325 is parallel to the bottom plane of the sliding groove 324. A limiting groove 326 is also formed on the bottom of the sliding groove 324. The limiting groove 326 penetrates the door panel 322 in the thickness direction.

[0028] The pushing wedge 323 is slidably received in the sliding groove 324. The thickness of the pushing wedge 323 is greater than the maximum distance between the sliding groove 324 and the bearing platform 340. The two side walls of the pushing wedge 323 are respectively attached to the door frame 321 and the groove wall of the sliding groove 324. When the pushing wedge 323 slides in the sliding groove 324, it can exert a pushing effect on the door panel 322, enabling the door panel 322 to move away from the bearing platform 340 until the door panel 322 disengages from the door frame 321. A limiting post 327 is installed on the side wall of the pushing wedge 323. The limiting post 327 is slidably inserted into the guiding groove 325. The sliding direction of the pushing wedge 323 can be restricted through the limiting post 327 to prevent the pushing wedge 323 from disengaging from the sliding groove 324. A connecting hole 328 is formed on the pushing wedge 323. The connecting hole 328 is arranged corresponding to the notch of the limiting groove 326. A limiting frame 329 is insertably and removably inserted into the connecting hole 328. The limiting frame 329 extends outside the door panel 322 through the limiting groove 326. By pulling the limiting frame to move along the limiting groove 326, the pushing wedge 323 can be driven to slide in the sliding groove 324. Since the thickness of the pushing wedge 323 is relatively large, the pushing wedge 323 can exert a pushing effect on the bottom of the sliding groove 324, and thus the pushing wedge 323 causes the door panel 322 to disengage from the door frame 321.

[0029] Preferably, insertion slots 330 are respectively formed on both sides of the sliding groove 324 on the edge of the door panel 322. A crowbar can be inserted into the two insertion slots 330. By using the crowbar, the moment for opening the door panel 322 can be extended, facilitating the staff to pry open the door panel 322.

[0030] As Figure 1 shown, the pipeline device 20 includes a heat supply pipeline 210 communicating with the inside of the furnace body 10, a heat distribution pipeline 220 installed on the heat supply pipeline 210, a feeding pipeline 230 connecting each heat storage chamber 30, and an evacuation pipeline 240.

[0031] One end of the heat supply pipeline 210 is connected to a heat source, and the other end of the heat supply pipeline 210 is in a blocked state. The heat distribution pipeline 220 is arranged corresponding to the furnace body 10 and is set according to the number of furnace bodies 10. One section of the heat distribution pipeline 220 communicates with the pipe wall of the heat supply pipeline 220, and the other end of the heat distribution pipeline 220 communicates with the inside of the furnace body 10. The high-temperature gas in the heat supply pipeline 210 can enter the furnace body 10 through the heat distribution pipeline 220, and the high-temperature gas heats the heat storage body 310 in the heat storage chamber 30. The feeding pipeline 230 is arranged along the arrangement direction of the furnace bodies 10, and the feeding pipeline 230 communicates with each furnace body 10. The waste liquid to be incinerated can be input into the furnace body 10 through the feeding pipeline 230. Under the heating of the heat storage body 310, the waste liquid can be incinerated and decomposed in the heat storage chamber 30. The evacuation pipeline 240 is installed above the above-mentioned heat storage chamber 30, and the evacuation pipeline 240 absorbs and discharges the decomposed gas in the heat storage chamber 30.

[0032] When the above-mentioned regenerative waste liquid incinerator is in use, high-temperature oxygen-rich gas is injected into the furnace body 10 through the heat supply pipeline 210. The high-temperature oxygen-rich gas heats the heat storage body 310, and the heat storage body 310 maintains a high-temperature environment in the heat storage chamber 30. The waste liquid to be decomposed can be sprayed and injected into the heat storage chamber 30 through the feeding pipeline 230. In the high-temperature and high-oxygen environment in the heat storage chamber 30, the waste liquid is decomposed into water and carbon dioxide, and the decomposition products can be discharged to the outside of the heat storage chamber 30 through the evacuation pipeline 240. When furnace shutdown maintenance is required, the limiting frame 329 is inserted into the connection hole 328. Outside the limiting groove 326, the pushing wedge block 323 is pulled and pushed to slide along the sliding groove 324 by the limiting frame 329. Under the oblique limitation of the sliding groove 324, the pushing wedge block 323 can push against the bottom of the sliding groove 324 until the door panel 322 is pushed out of the door frame 321. The insertion slot 330 on the door panel 322 is separated from the door frame 321. Inserting a crowbar into the insertion slot 330 can facilitate the opening of the door panel 322, facilitating the maintenance process of the furnace body 10 and the heat storage chamber 30.

[0033] Based on the above-mentioned ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
