Description

Technical Field

[0001] This utility model belongs to the field of high-salinity wastewater discharge treatment technology, and more specifically, it relates to a novel steam compression treatment device for zero-discharge treatment of high-salinity wastewater. Background Technology

[0002] High-salt wastewater treatment mainly uses mechanical steam recompression, which is a highly efficient and energy-saving evaporation crystallization process. Its core is to use a steam compressor to compress and heat secondary steam, turning it into high-temperature saturated steam, which is then recycled as a heat source for evaporation. During the evaporation process, some crystals will form on the inner wall, and the circulation pump needs to be stopped to flush it, which affects the evaporation speed and efficiency. In addition, the circulation pump control system is costly. Utility Model Content

[0021] like Figure 5 As shown, the limiting connection assembly 302 also includes: a support block 3021, a bracket 3022, an auxiliary locking rod 3023, a control pull rope 3024, and a trigger rod 3025; the support block 3021 is a hollow cuboid, and a limiting insertion hole is provided inside the threaded rotating rod 204, which is fixedly connected to the top support ring 301; the bottom of the bracket 3022 is fixedly connected to the bottom support ring 303, and the bracket 3022 slides into the support block 3021 and contacts the spring; the auxiliary locking rod 3023 can play an auxiliary limiting role; one end of the auxiliary locking rod 3023 slides into the bracket 3022 and contacts the spring; the left and right ends of the control pull rope 3024 are fixedly connected to two sets of auxiliary locking rods 3023; the top of the trigger rod 3025 slides into the bracket 3022, and the middle of the control pull rope 3024 passes through the top round hole of the bracket 3022.

[0022] like Figure 6 As shown, the cleaning component 4 includes: an outer support rod 401, an inner slide rod 402, a clamp 403, and a rubber cleaning ring 404; the bottom of the outer support rod 401 is fixedly connected to the top support ring 301; the bottom of the inner slide rod 402 is fixedly connected to the bottom support ring 303, and the top of the inner slide rod 402 slides through the outer support rod 401; the number of clamps 403 is set to two sets, and the clamps 403 are fixedly connected to the outer support rod 401 and the inner slide rod 402; the rubber cleaning ring 404 is fixedly installed on the inner side of the two sets of clamps 403.

[0023] The specific usage and function of this embodiment are as follows: In this invention, during use, wastewater enters the evaporation conveying pipe 103. As it flows, hot air from the hot gas conveying pipe 104 assists in the evaporation of the wastewater. Crystallization easily occurs in the evaporation conveying pipe 103. A motor at one end of the control lever 202 starts, and the control lever 202 rotates, controlling the rotation of the threaded rotating rod 204 via a bevel gear assembly. Since the threaded rotating rod 204 is threadedly connected to the top support ring 301, the support frame 203 restricts the rotation of the top support ring 301, causing it to descend. At this time, the rubber cleaning ring 404 is squeezed by two sets of clamps 403, causing a bulge in the middle. As the clamps 403 slide down, they contact the inner wall of the evaporation conveying pipe 103, scraping away any remaining crystals. When the bottom support ring 303 slides to its lowest point, the trigger rod 3025 is squeezed, causing it to slide upwards. The trigger rod 3025 slides and, through the deformation of the protrusion of the control rope 3024, pulls the auxiliary locking rod 3023 to slide inward, pulling it out through the limiting hole, releasing the limiting position of the bracket 3022. The bracket 3022 slides upward under the push of the spring, and the bracket 3022, the bottom support ring 303, and the inner support rod of the inner slide rod 402 rise, releasing the compression of the rubber cleaning ring 404. The protrusion in the middle of the rubber cleaning ring 404 retracts, and the rubber cleaning ring 404 rises again, without contacting the inner wall of the evaporation conveying pipe 103, thus not affecting the evaporation process. The inner slide rod 402 rises to its highest point and contacts the retaining ring 102. The inner slide rod 402 slides down and is pulled down again, allowing the auxiliary locking rod 3023 to re-insert into the limiting hole, forming a limit. The protrusion in the middle of the rubber cleaning ring 404 facilitates subsequent cleaning.
