Description

Technical Field

[0001] This utility model relates to the technical field of waste liquid incinerators that prevent slag blockage, and in particular to a waste liquid incinerator that prevents slag blockage. Background Technology

[0002] Wastewater containing inorganic salts is easily generated during the production process. When treating this type of wastewater, incineration is typically used to decompose it into water, carbon dioxide, and inorganic salts. The inorganic salts are then recovered through melting and cooling. For example, patent number CN20232324283.8 discloses a continuous saline wastewater incinerator for recoverable slag. This invention discloses using a purge pipe to blow inorganic salts onto a feed guide cylinder. The feed guide cylinder guides the flow of the molten inorganic salts, causing them to collect at the bottom of the recovery furnace. To prevent the molten inorganic salts from condensing and forming scale inside the furnace, purging and vibration are used to move the inorganic salts to the bottom. When the above-mentioned incinerator is in use, because the molten inorganic salt has a large spreading area on the closing feed tube and a fast heat dissipation rate, even with the assistance of purging and vibration, the inorganic salt is still prone to condensation and accumulation on the closing feed tube. If the condensed inorganic salt is not cleaned in time, it will affect the flow rate of other inorganic salts, eventually blocking the closing feed tube and other slag discharge structures, resulting in a reduction in the incineration efficiency of the waste liquid. Utility Model Content

[0003] The technical problem this invention aims to solve is that the inorganic salts condensed inside the incinerator affect the flow rate of the molten inorganic salts, thus affecting the incineration efficiency of the waste liquid.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a waste liquid incinerator for preventing slag blockage, including a furnace body, a burner installed in the furnace body, a slag discharge port provided on the furnace body, a replacement component installed in the slag discharge port, and a spiral conveying component installed outside the slag discharge port. The slag discharge port includes a slag discharge sleeve installed at the bottom of the furnace body and a cooling spiral tube surrounding the outside of the slag discharge sleeve. A heat exchange medium circulates in the cooling spiral tube. The replacement component includes an inclined sleeve inserted in the slag discharge sleeve and a pressing rotating block installed at the end of the slag discharge sleeve. The pressing rotating block has a waist-shaped structure. One end of the pressing rotating block is rotatably installed on the end of the slag discharge sleeve. After the other end of the pressing rotating block rotates, it presses down on the inclined sleeve.

[0005] Furthermore, the slag discharge port also includes an inclined furnace bottom, which is installed at the bottom of the furnace body, and the slag discharge sleeve is installed on the inclined furnace bottom.

[0006] Furthermore, a cooling cavity is provided on the side wall of the slag discharge sleeve, and the cooling spiral tube is housed in the cooling cavity.

[0007] Furthermore, the replacement component also includes a spline block mounted on the inclined sleeve, the slag discharge sleeve having a spline groove, and the spline block being inserted into the spline groove.

[0008] Furthermore, a pin is rotatably inserted into the end of the pressing block, and the pin is fixedly installed on the slag discharge sleeve.

[0009] Furthermore, the inner wall cross-section of the inclined sleeve is conical, and the inclined sleeve and the slag discharge sleeve are fitted together in a sealed manner.

[0010] Furthermore, the spiral conveying assembly includes a collection funnel disposed below the slag discharge sleeve, a conveying sleeve installed below the collection funnel, and a spiral conveyor installed in the conveying sleeve.

[0011] The beneficial effects of this utility model are that the inorganic salt precipitated in the furnace body eventually gathers in the slag discharge sleeve. An inclined sleeve is added to the slag discharge sleeve, and the inorganic salt is gradually discharged along the inclined inner wall of the inclined sleeve. At the same time, the nesting structure of the inclined sleeve and the slag discharge sleeve is controlled by the rotation of the clamping block, which speeds up the installation and removal of the inclined sleeve from the slag discharge sleeve. When the cooling spiral tube provides transitional cooling for the inorganic salt in the inclined sleeve, the inorganic salt can be prevented from condensing and clogging in the inclined sleeve by replacing the inclined sleeve, thus ensuring the incineration efficiency of the waste liquid.

[0014] 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.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] like Figures 1 to 5 As shown, this embodiment provides a waste liquid incinerator to prevent slag blockage, including a furnace body 10, a burner 20 installed in the furnace body 10, a slag discharge port 30 provided on the furnace body 10, a replacement component 40 installed in the slag discharge port 30, and a spiral conveying component 50 installed outside the slag discharge port 30.

[0017] Combustion air and vaporized saline waste liquid are injected into the furnace body 10. Simultaneously, the burner 20 increases the internal temperature of the furnace body 10, causing the saline waste liquid to burn and decompose within the furnace body 10, precipitating inorganic salts. The inorganic salts settle along the furnace body 10 into the slag discharge port 30 and are discharged through the slag discharge port 30 into the screw conveyor assembly 50. The screw conveyor assembly 50 then transports the inorganic salts to a designated container. When an excessive amount of inorganic salt condenses on the side wall of the slag discharge port 30, the replacement assembly 40 is used to remove the inorganic salt from the slag discharge port 30, and a new slag discharge port 30 component is installed to ensure unobstructed flow of inorganic salts.

[0018] The furnace body 10 is preferably a regenerative incinerator, meaning that a heat storage medium is stored inside the furnace body 10. The heat generated during the incineration of the saline waste liquid heats the heat storage medium, thus saving energy consumption during waste liquid incineration. The burner 20 is installed inside the furnace body 10 and is used to ignite the waste liquid inside the furnace body 10 to start the combustion process. The inorganic salts produced after the waste liquid incinerates in the furnace body 10 settle to the bottom of the furnace.

[0019] The slag discharge port 30 includes an inclined furnace bottom 310, a slag discharge sleeve 320 installed on the inclined furnace bottom 310, and a cooling spiral pipe 330 surrounding the outside of the slag discharge sleeve 320. The inclined furnace bottom 310 is installed at the bottom of the furnace body 10. After inorganic salts settle, they accumulate on the inclined furnace bottom 310 and flow along the inclined furnace bottom 310 to the opening of the slag discharge sleeve 320. A cooling cavity 322 is provided in the side wall of the slag discharge sleeve 320. The cooling cavity 322 accommodates the cooling spiral pipe 330. A heat exchange medium circulates in the cooling spiral pipe 330. The heat exchange medium exchanges heat with the inorganic salt residue in the slag discharge sleeve 320 and carries the heat to an external heat recovery system, where the heat of the inorganic salts is recovered through contact heat exchange.

[0020] The replacement component 40 includes an inclined sleeve 410 installed in the slag discharge port 30, a spline block 420 installed on the inclined sleeve 410, and a clamping rotating block 430 installed at the end of the slag discharge sleeve 320.

[0021] An inclined sleeve 410 is inserted into a slag discharge sleeve 320. The inclined sleeve 410 and the slag discharge sleeve 320 are in a sealed fit. The inner wall of the inclined sleeve 410 has a conical cross-section. The end of the inclined sleeve 410 is flush with the inclined furnace bottom 310. A spline block 420 is axially mounted on the outer wall of the inclined sleeve 410. A spline groove 321 is opened on the inner wall of the slag discharge sleeve 320. The spline block 420 can be slidably inserted into the spline groove 321. By utilizing the fit between the spline block 420 and the spline groove 321, the inclined sleeve 410 is positioned and inserted into the slag discharge sleeve 320, and the inclined sleeve 410 is prevented from rotating inside the slag discharge sleeve 320. The clamping rotating block 430 is rotatably mounted on the end of the slag discharge sleeve 320. Preferably, the clamping rotating block 430 has a waist-shaped structure. One end of the clamping rotating block 430 is rotatably mounted on the slag discharge sleeve 320, and the other end of the clamping rotating block 430, when rotated, can press against the inclined sleeve 410. Preferably, a pin 431 is rotatably inserted into the end of the clamping rotating block 430, and the pin 431 is fixedly mounted on the slag discharge sleeve 320. When too much inorganic salt condenses, or when it is necessary to replace the inclined sleeve 410 according to the type of inorganic salt to change the angle of the conical structure of the inner wall cross section, first rotate the clamping block 430 on the slag discharge sleeve 320 until the clamping block 430 rotates away from the surface of the inclined sleeve 410. Take out the old inclined sleeve 410 along the spline block 420 and spline groove 321, and insert the new inclined sleeve 410. Rotate the clamping block 430 again to lock the inclined sleeve 410 on the slag discharge sleeve 320.

[0022] The screw conveyor assembly 50 includes a collection funnel 510 disposed below the slag discharge sleeve 320, a conveying sleeve 520 installed below the collection funnel 510, and a screw conveyor 530 installed in the conveying sleeve 520. The diameter of the collection funnel 510 is larger than the diameter of the slag discharge sleeve 320, allowing inorganic salts in the slag discharge sleeve 320 to fall into the collection funnel 510 and enter the conveying sleeve 520 along the collection funnel 510. The screw conveyor 530 is rotatably installed in the conveying sleeve 520. When the screw conveyor 530 is started, it can convey the inorganic salts to the end of the conveying sleeve 520 and into the inorganic salt collection device.

[0023] In operation, the aforementioned slag-blocking-resistant waste liquid incinerator injects combustion air and saline waste liquid into the furnace body 10 and starts the burner 20. The saline waste liquid is burned and decomposed within the furnace body 10, generating carbon dioxide and water, and inorganic salts are released. The carbon dioxide and water are released through venting, while the inorganic salts, in a molten state, accumulate in the inclined furnace bottom 310 at high temperatures. Guided by the inclined furnace bottom 310, the inorganic salts accumulate near the slag discharge sleeve 320 port. The inclined sleeve 410 in the slag discharge sleeve 320 is discharged into the collection funnel 510. Inorganic salt is discharged through the collection funnel 510 into the conveying sleeve 520 and discharged from the conveying sleeve 520 by the screw conveyor 530. When the inclined sleeve 410 needs to be replaced, the clamping block 430 is rotated, and the inclined sleeve 410 is slid out along the spline block 420 and the spline groove 321. A new inclined sleeve 410 is then inserted, which can effectively reduce the time for inorganic salt to condense and block the inclined sleeve 410.

[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.
