Description

Technical Field

[0001] The utility model relates to the technical field of single-effect evaporators, in particular to a desalination single-effect evaporation device for a hazardous waste incinerator. Background Technique

[0002] During industrial production, a large amount of waste liquid will be generated. In order to protect the environment, the waste liquid needs to be filtered and treated before it can be discharged. When concentrating the salt-containing wastewater generated by industry, a single-effect evaporator is required to evaporate and treat the salt-containing wastewater. After the salt-containing wastewater is evaporated, salt-containing solids are generated, and the salt-containing solids need to be further treated by a hazardous waste incinerator later;

[0003] The patent application No. CN202010508433.3 discloses a desalination single-effect evaporator dedicated to a hazardous waste incinerator, which includes a heating chamber. A number of heating tubes are installed inside the heating chamber. First support feet are installed on both sides of the lower end of the heating chamber. A first high-temperature resistant PVC board is installed inside the heating chamber. A condensate water pipe is installed below the outside of the heating chamber. An evaporation chamber is installed on one side of the heating chamber. A wastewater circulation tank is installed at the lower end of the evaporation chamber. Second support feet are installed on both sides of the lower end of the wastewater circulation tank;

[0004] When the above patent structure is used, the waste liquid is first heated to make it boil and generate steam, and then the boiled waste liquid and the generated steam are respectively processed. However, when the above patent heats the waste liquid, it directly heats the waste liquid without first filtering and treating the waste liquid. Therefore, there are many solid impurities in the waste liquid. The salt-containing solids generated by evaporation are mixed with the solid impurities, which is inconvenient for the subsequent waste incinerator to incinerate the salt-containing solids. At the same time, when the heating tubes heat the waste liquid, because the heating tubes are fixed, only the waste liquid near the heating tubes can be heated, and it is inconvenient to heat the waste liquid in other positions. Therefore, the waste liquid will be unevenly heated, and the impurities in the waste liquid are easy to sink to the bottom, reducing the heating and evaporation effect of the waste liquid.

[0030] Below the inside of the purification chamber 4, a circulating filter frame 401 is fixedly connected. Above the inside of the purification chamber 4, a drying plate 402 is fixedly connected. Inside the purification chamber 4 and above the drying plate 402, a purification box 403 is fixedly connected. Inside the purification box 403, a purification solution 404 is provided. Inside the purification box 403, a purification pipe 405 is fixedly connected. Inside the purification chamber 4 and above the purification box 403, an exhaust pipe 406 is fixedly connected;

[0031] At the rear of the furnace box 1, at the filtration chamber 2, and at the heating chamber 3, a pump body 5 is fixedly installed. Between the filtration chamber 2 and the heating chamber 3, an upper diversion pipe 501 is fixedly connected. Between the heating chamber 3 and the purification chamber 4, a lower diversion pipe 502 is fixedly connected. Between the purification chamber 4 and the filtration chamber 2, a return pipe 503 is fixedly connected. By providing a crystallization fluidized bed at the bottom of the filtration chamber 2, the wastewater entering the bottom of the filtration chamber 2 can be brought into contact with the crystallization fluidized bed to form salt-containing solids. At the same time, an opening and closing door is installed at the filtration chamber 2. Opening the opening and closing door can remove the salt-containing solids. By fixedly installing a heater on the rotating frame 304, the heat generated by the heater can be transferred to the rotating shaft 308 and the stirring rod 309 made of a metal heat-conducting material. At the same time, the heater can be powered by a storage battery provided inside its housing, so that the rotating shaft 308 and the stirring rod 309 can heat-treat the wastewater.

[0032] Furthermore, the first filter frame 202 and the third filter frame 204 are inclined downward to the right, the second filter frame 203 is inclined downward to the left. The bottom ends of the first filter frame 202, the second filter frame 203, and the third filter frame 204 are located at the port of the slag discharge port 201. There is a gap between the first filter frame 202, the second filter frame 203, and the third filter frame 204 and the inclined plate 205, which is convenient for the first filter frame 202, the second filter frame 203, and the third filter frame 204 to perform multi-stage filtration treatment on the wastewater. The filtered solid impurities can be discharged from the slag discharge port 201.

[0033] Further, one end of the spring 306 is fixedly connected to the inner wall of the turntable chute 305, and the other end of the spring 306 is fixedly connected to the sliding sleeve 307. The bottom end of the rotating shaft 308 is rotatably connected to the bottom ring 303, facilitating the sliding sleeve 307 to drive the rotating shaft 308 to move back and forth through the extension or contraction of the spring 306, and the bottom ring 303 can support the rotation of the bottom end of the rotating shaft 308.

[0034] Further, the inner side surface of the annular groove 311 is in an annular concave-convex shape, the inner rack 312 and the outer rack 313 are arranged in an alternating manner, and the gear disk 310 meshes with the inner rack 312 and the outer rack 313. When the gear disk 310 moves from the concave part of the annular groove 311 to the convex part side, the gear disk 310 can drive the rotating shaft 308 and the stirring rod 309 to move inward, and at this time, the sliding sleeve 307 drives the spring 306 to extend. Similarly, when the gear disk 310 moves from the convex part of the annular groove 311 to the concave part side, the spring 306 can extend to make the gear disk 310 drive the rotating shaft 308 and the stirring rod 309 to move outward. Therefore, the rotating shaft 308 and the stirring rod 309 can stir the wastewater inward or outward again.

[0035] Further, a solution for purifying the salt-containing wastewater vapor is provided inside the purification tank 403. The bottom end of the purification pipe 405 penetrates the bottom surface of the purification tank 403, and the top end of the purification pipe 405 is inserted into the purification solution 404. The outer end of the exhaust pipe 406 extends to the outside of the purification chamber 4. Entering the purification solution 404 through the purification pipe 405, the purification solution 404 is a special purification solution for treating the steam generated by the salt-containing wastewater. Therefore, when the steam enters the purification solution 404, it can be fully mixed and purified with it.

[0036] Further, the filtration chamber 2 is connected to the heating chamber 3 through the upper diversion pipe 501, the heating chamber 3 is connected to the purification chamber 4 through the lower diversion pipe 502, and the purification chamber 4 is connected to the filtration chamber 2 through the return pipe 503. The upper diversion pipe 501, the lower diversion pipe 502, and the return pipe 503 are all connected to the pump body 5 at various locations, facilitating the filtered wastewater inside the filtration chamber 2 to be transported to the heating chamber 3 through the upper diversion pipe 501, the heated wastewater inside the heating chamber 3 to be transported to the purification chamber 4 through the lower diversion pipe 502, and the wastewater inside the purification chamber 4 to be transported back to the filtration chamber 2 through the return pipe 503 for cyclic filtration.

[0037] When in use, the salt-containing wastewater is poured into the water inlet box 6, and the wastewater can be evenly discharged to the No. 1 filter frame 202 through the water distributor 7 inside the water inlet box 6. After the wastewater is filtered by the No. 1 filter frame 202, the solid impurities remain on the No. 1 filter frame 202 and slide down obliquely along the surface of the No. 1 filter frame 202, and the solid impurities are discharged from the slag discharge port 201 there. The wastewater filtered by the No. 1 filter frame 202 enters the inclined plate 205, and can be discharged to the No. 2 filter frame 203 again through the drain port 206. Similarly, it can be seen from the above steps that the wastewater can be filtered again through the No. 2 filter frame 203 and the No. 3 filter frame 204, and the filtered solid impurities can be discharged through the slag discharge port 201. The filtered wastewater enters the bottom of the filter chamber 2 The wastewater filtered in the filter chamber 2 can be transported to the heating chamber 3 through the pump body 5 and the upper guide pipe 501, and the heat can be transferred to the rotating shaft 308 and the stirring rod 309 through the heater arranged on the rotating frame 304, so the wastewater can be heated by the rotating shaft 308 and the stirring rod 309. At the same time, the starting motor 302 can drive the rotating frame 304 to rotate, and then the rotating frame 304 can drive the rotating shaft 308 to rotate along the circumferential direction of the heating chamber 3, so that the wastewater can be stirred in the circumferential direction, and the rotating shaft 308 can drive the gear disc 310 to rotate along the circumferential direction of the heating chamber 3. When the gear disc 310 is engaged with the inner rack 312, the gear disc 310 can drive the rotating shaft 308 to rotate in the positive direction. When the outer rack 313 of the gear disc 310 is engaged, The toothed disc 310 drives the rotating shaft 308 to rotate in the opposite direction, so that the rotating shaft 308 can drive the stirring rod 309 to rotate in the forward and reverse directions, so that the stirring rod 309 can stir the wastewater again, and when the toothed disc 310 moves from the concave part of the annular groove 311 to the convex part thereof, the toothed disc 310 can drive the rotating shaft 308 and the stirring rod 309 to move inward, and at this time, the sliding sleeve 307 drives the spring 306 to stretch. Similarly, when the toothed disc 310 moves from the convex part of the annular groove 311 to the concave part thereof, the toothed disc 310 can drive the rotating shaft 308 and the stirring rod 309 to move outward through the stretching of the spring 306, so that the rotating shaft 308 and the stirring rod 309 can stir the wastewater inward or outward again, so that the wastewater can be evenly stirred and heated to make the waste liquid boil. Steam is generated, and the waste liquid after boiling in the heating chamber 3 can be transported to the purification chamber 4 through the pump body 5 and the lower guide pipe 502, and the waste liquid can be filtered through the circulation filter frame 401. The filtered impurities remain on the circulation filter frame 401, and the filtered waste liquid enters the bottom of the purification chamber 4, and the waste liquid at the bottom of the purification chamber 4 can be transported to the filter chamber 2 again through the pump body 5 and the reflux pipe 503. Therefore, the waste water cycle can be filtered and evaporated. The steam generated by the evaporation of the boiling waste liquid in the purification chamber 4 floats upward. As the amount of steam in the purification chamber 4 increases, its internal pressure can be increased. Therefore, the steam in the purification chamber 4 is dried by the drying plate 402 and then enters the purification solution 404 through the purification pipe 405.Therefore, when the steam enters the purification solution 404, it can be fully mixed with the solution, and bubbles are generated inside the purification solution 404. The generated bubbles float upward to the liquid surface inside the purification solution 404, and the gas finally enters above the purification tank 403 and is finally discharged through the exhaust pipe 406. By providing a crystallization fluidized bed at the bottom of the filtration chamber 2, the wastewater entering the bottom of the filtration chamber 2 can be brought into contact with the crystallization fluidized bed to form salt-containing solids.
