Description

Technical Field

[0001] This utility model relates to the technical field of incineration devices with waste residue cleaning structures, and in particular to an incineration device with a waste residue cleaning structure. Background Technology

[0002] When incinerating waste liquid in an incinerator, silica dust and other waste residues precipitate out at high temperatures and eventually settle on the side walls and bottom of the incinerator. Patent CN119436162A discloses an incineration device for treating saline and chlorine-containing waste liquid. Specifically, it discloses a method that uses a rotating discharge structure to push the waste residue produced during incineration towards the discharge port, controlling the discharge of the waste residue through rotation to prevent inorganic salts from clogging the discharge channel. However, in this type of equipment, the discharge structure needs to rotate continuously. Under high-temperature conditions, the auxiliary rotating components, such as bearings and rotors, are prone to thermal deformation, causing the rotation process to become uneven and affecting the discharge efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the high-temperature environment of the incinerator in the prior art affects the waste residue discharge mechanism and reduces the slag discharge efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an incineration device with a waste residue cleaning structure, including a furnace body, a slag discharge assembly installed on the furnace body, and a cleaning assembly detachably connected to the slag discharge assembly. The slag discharge assembly includes a collecting furnace bottom installed on the furnace body, a slag discharge pipe installed on the collecting furnace bottom, and a connecting pipe detachably connected to the slag discharge pipe. The cleaning assembly includes a control sleeve connected to the slag discharge pipe, a retainer installed on the collecting furnace bottom and the control sleeve, a spiral scraper rotatably installed on the retainer, and a control sleeve for the spiral scraper. A long-handled wrench for rotating the spiral scraper, with both ends of the spiral scraper inserted into the retainer of the collecting furnace bottom and the control sleeve, respectively, and the edge of the spiral scraper overlapping the inner wall of the slag discharge pipe.

[0005] Furthermore, the end of the connecting pipe is threaded onto the end of the slag discharge pipe, and the control sleeve and the connecting pipe adopt the same structure for connecting to the slag discharge pipe.

[0006] Furthermore, the central shaft end of the spiral scraper has a polygonal prism structure, and the end of the spiral scraper extends out of the control sleeve through the retainer. The long-handled wrench can be sleeved onto the polygonal prism end of the spiral scraper.

[0007] Furthermore, a cooling chamber is formed in the side wall of the slag discharge pipe, and a heat exchange medium circulates in the cooling chamber to cool and protect the slag discharge pipe.

[0008] Furthermore, one end of the connecting pipe is detachably connected to the slag discharge pipe, and the other end of the connecting pipe is connected to the inorganic salt collection container.

[0009] Furthermore, a burner is installed on the top of the furnace body, which increases the temperature inside the furnace body.

[0010] Furthermore, a feed pipe is installed on the top of the furnace body to discharge waste gas into the furnace body, and an air inlet pipe is installed on the side wall of the furnace body to discharge oxygen into the furnace body.

[0011] Furthermore, a heat storage body is installed inside the furnace body, and the heat storage body is made of honeycomb ceramic heat storage material.

[0012] The beneficial effect of this utility model is that when the discharge speed of waste residue in the slag discharge pipe decreases, the connecting pipe is removed from the slag discharge pipe, the spiral scraper is inserted into the slag discharge pipe and fixed using a control sleeve, and the spiral scraper is rotated in the slag discharge pipe using a long-handled wrench. The spiral scraper scrapes the side wall of the slag discharge pipe to remove slag. After the slag removal operation is completed, the control sleeve and spiral scraper can be removed from the slag discharge pipe and reconnected. The upper connecting pipe ensures that the slag discharge operation is not affected. This process can reduce the impact of high temperature on the slag discharge components, prevent the spiral scraper from deforming under high temperature, improve slag discharge efficiency, and reduce slag discharge cost.

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] like Figures 1 to 5 As shown, this embodiment provides an incineration device with a waste residue cleaning structure, including a furnace body 10, a slag discharge assembly 20 installed on the furnace body 10, and a cleaning assembly 30 detachably connected to the slag discharge assembly 20.

[0017] First, the temperature inside the furnace body 10 is raised to the level required for incinerating the atomized waste liquid. Combustion air or oxygen is injected, along with the atomized waste liquid. The atomized waste liquid is burned and decomposed into carbon dioxide and water in a high-temperature, high-oxygen environment, while waste residue is released. The carbon dioxide and water are discharged through venting or other means. The waste residue adheres to the furnace wall or bottom sidewalls of the furnace body. The waste residue gradually flows and gathers near the slag discharge assembly 20, and inorganic salts are discharged from the furnace body 10 through the slag discharge assembly 20. When the discharge rate of inorganic salts decreases or the temperature inside the furnace body 10 drops, the cleaning assembly 30 is installed in the slag discharge assembly 20 to clean the discharge channel of the slag discharge assembly 20.

[0018] The furnace body 10 is generally a cavity structure. A burner 110 and a feed pipe 120 are installed on the top of the furnace body 10, and an air inlet pipe 130 is installed on the side wall of the furnace body 10. A heat storage body 140 is installed inside the furnace body 10. The burner 110 increases the internal temperature of the furnace body 10. When the temperature of the furnace body 10 reaches the combustion level, atomized waste liquid is discharged into the furnace body 10 through the feed pipe 120, and oxygen is simultaneously discharged into the furnace body 10 through the air inlet pipe 130. The waste gas generates heat during combustion and decomposition inside the furnace body 10. This heat is absorbed by the heat storage body 140, which is made of honeycomb ceramic heat storage material. The heat storage body 140 can maintain the ambient temperature inside the furnace body 10 and reduce the fuel consumption of the burner 110.

[0019] The slag discharge assembly 20 includes a collecting furnace bottom 210 installed on the furnace body 10, a slag discharge pipe 220 installed on the collecting furnace bottom 210, and a connecting pipe 240 detachably connected to the slag discharge pipe 220.

[0020] The collecting furnace bottom 210 is roughly conical in shape. Molten inorganic salts inside the furnace body 10 gradually converge along the inclined structure of the collecting furnace bottom 210 to the vicinity of the slag discharge pipe 220. The slag discharge pipe 220 connects to the inner and outer sides of the furnace body 10. Waste slag is discharged from the slag discharge pipe 220. A cooling chamber 221 is opened in the side wall of the slag discharge pipe 220. A cooling pipe 230 is fitted onto the outside of the slag discharge pipe 220 with an interference fit. A heat exchange medium circulates in the cooling chamber 221. The heat exchange medium cools and protects the slag discharge pipe 220, while regulating the temperature of the inorganic salts to prevent the temperature of the slag discharge pipe 220 from becoming too high and causing high-temperature damage to the furnace body 10 and the slag discharge assembly 20. One end of the connecting pipe 240 is detachably connected to the slag discharge pipe 220, and the other end of the connecting pipe 240 is connected to the inorganic salt collecting container. The connecting pipe 240 and the slag discharge pipe 220 can be connected by screwing or by flange connection. In this embodiment, screwing is preferred, that is, the end of the connecting pipe 240 is fitted onto the end of the slag discharge pipe 220 by thread engagement.

[0021] The cleaning assembly 30 includes a control sleeve 310 that can replace the connecting pipe 240 and be installed on the slag discharge pipe 220, a retainer 320 installed on the collecting furnace bottom 210 and the control sleeve 310, a spiral scraper 330 rotatably mounted on the retainer 320, and a long-handled wrench 340 for controlling the rotation of the spiral scraper 330.

[0022] The end of the control sleeve 310 adopts the same structure as the connecting pipe 240, connecting to the slag discharge pipe 220. When the slag discharge pipe 220 needs to be cleaned, the control sleeve 310 is installed on the slag discharge pipe 220 instead of the connecting pipe 240. The two ends of the spiral scraper 330 in the control sleeve 310 are respectively inserted into the collecting furnace bottom 210 and the retainer 320 of the control sleeve 310. The edge of the spiral scraper 330 overlaps the inner wall of the slag discharge pipe 220. When the spiral scraper 330 rotates in the slag discharge pipe 220 and the control sleeve 310, the spiral scraper 330 scrapes the residue on the inner wall of the slag discharge pipe 220 and pushes the waste residue along the inner wall of the slag discharge pipe 220 to complete the cleaning of inorganic salts on the inner wall of the slag discharge pipe 220. To prevent burns during cleaning, the central shaft end of the spiral scraper 330 extends out of the control sleeve 310 through the retainer 320. The central shaft end of the spiral scraper 330 has a polygonal prism structure. A long-handled wrench 340 can be inserted under the control sleeve 310. The long-handled wrench 340 is fitted onto the end of the spiral scraper 330 that extends out of the control sleeve 310. The spiral scraper 330 is controlled to rotate outside the slag discharge pipe 220 using the long-handled wrench 340.

[0023] In operation, the burner 110 first raises the temperature inside the furnace body 10. When the temperature inside the furnace body 10 reaches the specified standard, combustion-supporting gas and atomized waste liquid are injected sequentially. They burn and decompose inside the furnace body 10, and the heat generated by the decomposition is absorbed by the heat storage body 140, which maintains the combustion temperature inside the furnace. The waste residue generated during the combustion of the waste liquid is collected along the furnace bottom 210 and flows into the slag discharge pipe 220. The waste residue flows along the slag discharge pipe 220 and the connecting pipe 240 to a container for storing waste residue. When the flow rate of the waste slag decreases or the temperature inside the furnace body 10 drops, and it is necessary to clean the residue in the slag discharge pipe 220, the connecting pipe 240 is removed from the slag discharge pipe 220, and the spiral scraper 330 is inserted through the opening of the slag discharge pipe 220. After the end of the spiral scraper 330 is inserted into the retainer 320 on the collecting furnace bottom 210, the retainer 320 in the control sleeve 310 is fitted onto the end of the spiral scraper 330. The control sleeve 310 is then fixed to the slag discharge pipe 220 by the installation structure. Then, the spiral scraper 330 in the control sleeve 310 is rotated using a long-handled wrench 340. When the spiral scraper 330 rotates, it scrapes the residue on the pipe wall of the slag discharge pipe 220, and the inorganic salts fall out of the retainer 320. After cleaning the slag discharge pipe 220, the control sleeve 310 is replaced with the connecting pipe 240, and the waste gas combustion operation continues.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
