Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically to a desulfurization wastewater evaporation device. Background Technology

[0002] The desulfurization wastewater evaporation device is a specialized device for treating desulfurization wastewater. It evaporates the water in the wastewater, thereby concentrating the harmful substances in the wastewater for easier subsequent treatment.

[0003] Chinese Patent Publication No. CN220926336U discloses a desulfurization wastewater evaporation device, including an evaporation tank and a preheating tank, which are connected by a water supply pump. The evaporation tank has a steam discharge port at its upper end. Inside the evaporation tank are several inclined and staggered heating plates, with absorbent cloth detachably fixed to the upper surface of each heating plate. A circulation pump is connected to the bottom of the evaporation tank, with its inlet extending to the bottom of the evaporation tank and its outlet extending to the upper part of the evaporation tank. The desulfurization wastewater is absorbed by the absorbent cloth and evaporated under the action of the heating plates. The preheating tank has a heat exchanger connected to the steam discharge port. Compared with existing technologies, this invention has the advantages of: heat exchange between steam and wastewater via the heat exchanger, preheating the wastewater and improving energy utilization efficiency; and the design of multiple inclined and staggered heating plates and absorbent cloth increases the heating area, improves evaporation efficiency, and accelerates wastewater treatment.

[0004] In the aforementioned prior art, desulfurization wastewater is circulated and sprayed onto an absorbent cloth, which then absorbs the wastewater. A heating plate is used to heat the wastewater, causing it to evaporate and separate from impurities and residues. However, the location where the circulating pump sprays the desulfurization wastewater is fixed and too concentrated, which can easily lead to incomplete spraying of the desulfurization wastewater onto the absorbent cloth, resulting in uneven humidity of the absorbent cloth. Furthermore, since the wastewater flows continuously from top to bottom, residual residues are easily washed back into the wastewater at the bottom of the evaporator by the water flow and re-enter the circulation. This requires frequent replacement of the absorbent cloth, which is quite cumbersome. Utility Model Content

[0081] Working principle:

[0082] In use, the water injection pipe 108 is connected to the delivery end of the desulfurization wastewater, the desulfurization wastewater is injected into the bottom of the desulfurization wastewater evaporation tank 1, and then the circulating pump 103 is opened to transport the desulfurization wastewater in the desulfurization wastewater evaporation tank 1 to the shunt pipe 106 through the delivery pipe 104 and the telescopic corrugated pipe 105, and finally sprayed onto the water absorption cloth 102 above the heating plate 101 through the nozzle 107, so that the desulfurization wastewater is absorbed by the water absorption cloth 102. During the process, the motor one 201 can be turned on to drive the reciprocating screw rod one 2 to rotate. The rotating reciprocating screw rod two 204 can drive the screw rod two 204 to rotate on the rotating seat 205 through the meshing of the linkage bevel gear 202 and the driven bevel gear 206. The rotating reciprocating screw rod two 204 can drive the screw slide 203 to reciprocate on the guide bar 207 through the screw thread cooperation between the reciprocating screw rod two 204 and the screw slide 203, so that the screw slide 203 drives the shunt pipe 106 and the nozzle 107 to reciprocate, and the desulfurization wastewater is uniformly sprayed on the water absorption cloth 102.

The residues in the wastewater can be washed off the water absorption cloth 102 by the nozzle 107 and fall into the semicircular sieve plate 4.

At the same time, the reciprocating screw rod one 2 can drive the sliding seat 3 to reciprocate through the screw thread cooperation between the reciprocating screw rod one 2 and the sliding seat 3. The sliding seat 3 will slide on the guide rod 306 to avoid deviation. The continuously moving sliding seat 3 can drive the sliding connecting rod 301 to move. At this time, the moving sliding connecting rod 301 will slide on the linkage sliding rod 304 through the sliding hole 305, thereby driving the bristles 302 to clean the impurities on the surface of the water absorption cloth 102, preventing the impurities from adhering to the reciprocating screw rod one 2. In cooperation with the spraying and washing of the wastewater, the impurities on the surface of the water absorption cloth 102 can be cleaned more thoroughly.

The spiral push piece 405 can push the impurities and residues on the semicircular sieve plate 4 out of the residue discharge pipe 401 when rotating, so as to clean the impurities.
