Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a high-concentration wastewater evaporation self-cleaning system. Background Art

[0002] Wastewater evaporators play a vital role in industrial wastewater treatment. However, pipe blockage and scaling often hinder the stable operation of the equipment. To address this problem, we first need to deeply understand the causes of pipe blockage and scaling and implement a series of targeted preventive measures. Pipe blockage is primarily caused by the accumulation of impurities and particulate matter within the heat exchange tubes of wastewater evaporators over time. Furthermore, minerals such as calcium and magnesium in the water precipitate during the evaporation process and adhere to the tube walls. These minerals gradually accumulate under high temperature conditions, forming a hard scale layer that seriously affects the heat transfer efficiency and operational stability of the evaporator.

[0003] In order to solve the problems existing in the prior art, the utility model with publication number CN217868178U discloses a wastewater concentration and evaporation device (hereinafter referred to as prior art 1), comprising a tank body, wherein support plates are fixedly provided on the upper inner wall and the middle inner wall of the tank body, and the top array of the support plate located above is penetrated and fixedly embedded with a plurality of heat exchange tubes, the bottom ends of the heat exchange tubes all penetrate the support plate located below and extend to the bottom of the support plate, a liquid storage plate is slidably provided on the lower inner wall of the tank body, the top array of the liquid storage plate is fixedly provided with a plurality of cleaning pipes matching the heat exchange tubes, the cleaning pipes are all located directly below the adjacent heat exchange tubes, the upper parts of the cleaning pipes are each provided with a plurality of water outlet holes in a circular array, the top array of the liquid storage plate is penetrated and fixedly embedded with a plurality of downpipes, the bottom ends of the downpipes all extend to the bottom of the liquid storage plate, and a liquid inlet pipe is fixedly provided at the bottom end of one side of the liquid storage plate.

[0004] Although the heat exchange tube can be cleaned by the cleaning pipe provided in the prior art 1, when the inner wall of the heat exchange tube is directly flushed through the water outlet hole provided on the cleaning pipe in the prior art 1, the contact time between the cleaning water and the inner wall of the heat exchange tube is short, and the reaction time between the cleaning water and the calcium magnesium carbonate attached to the wall of the heat exchange tube is limited, thereby affecting the cleaning efficiency and cleaning effect of the cleaning water on the inner wall of the heat exchange tube. Utility Model Content

[0005] The purpose of the utility model is to provide a high-concentration wastewater evaporation self-cleaning system, which, during actual use, can solve the problem in the prior art that the contact time between the pipe washing water and the inner wall of the heat exchange tube is short, which affects the cleaning efficiency and cleaning effect of the pipe washing water on the inner wall of the heat exchange tube.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A high-concentration wastewater evaporation self-cleaning system includes a tank body and a heat exchange component installed in the tank body, a heat exchange cavity is formed between the heat exchange component and the tank body, an air inlet pipe, an air outlet pipe and a liquid inlet pipe are connected to the tank body, a cleaning disk is slidably installed in the tank body, and a plurality of cleaning pipes are installed on the cleaning disk, and the cleaning pipes are used to clean the heat exchange component;

[0008] A liquid cavity is provided in the cleaning tray, and a high-pressure pipe communicating with the liquid cavity is connected to the cleaning tray; a first water outlet is provided at the top of the cleaning pipe, a drain pipe is fixedly embedded in the cleaning tray, and the bottom end of the drain pipe passes through the tank body and extends to the bottom of the tank body; a cleaning portion is fixedly connected to the top end of the cleaning pipe, and a blocking portion is fixedly connected to the bottom end of the cleaning pipe;

[0009] A driving device for driving the cleaning disc to move vertically up and down is installed in the tank body.

[0010] Preferably, the drain pipe is a telescopic pipe, and the bottom end of the drain pipe is fixedly connected to the tank body.

[0011] Preferably, a second water outlet hole is provided below the first water outlet hole, and the second water outlet hole and the first water outlet hole are arranged alternately.

[0012] Preferably, the first water outlet hole and the second water outlet hole are arranged to be inclined downward.

[0013] Preferably, a guide surface is provided on the blocking portion.

[0014] Preferably, the cleaning portion has a cleaning slope.

[0015] Preferably, a condenser pipe communicating with the heat exchange cavity is installed on the tank body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the air inlet pipe is used to input hot steam into the heat exchange chamber. When wastewater enters the heat exchange tube through the liquid inlet pipe, the hot steam heats the heat exchange tube and then exchanges heat with the wastewater in the liquid inlet pipe. Steam generated by the heated wastewater is output to the outside of the tank through the air outlet pipe, and the evaporated waste liquid is discharged from the tank through a plurality of drain pipes provided on the cleaning tray.

[0021] When the inner wall of the heat exchange tube needs to be cleaned, the driving device drives the cleaning disc to rise to the cleaning portion and the blocking portion to block the liquid inlet and liquid outlet of the heat exchange tube respectively. Then, a high-pressure pipe connected to the cleaning disc can be used to input high-pressure pipe cleaning liquid into the liquid cavity. When the high-pressure pipe cleaning liquid enters the closed area formed between the cleaning pipe and the heat exchange tube through the first water outlet hole, the inner wall of the heat exchange tube can be flushed.

[0022] After the heat exchange tube is sealed by arranging the cleaning part and the blocking part, the tube washing liquid entering the closed area formed between the heat exchange tube and the cleaning tube can fully react with the calcium magnesium carbonate product attached to the inner wall of the heat exchange tube; after the tube washing liquid fully reacts with the calcium magnesium carbonate product, the cleaning disc is driven by the driving device to move vertically downward, and the cleaning part moving vertically downward under the drive of the driving device can scrape off the impurities remaining on the inner wall of the heat exchange tube after fully reacting with the tube washing water, thereby further improving the cleaning effect of the heat exchange tube.

The pipe washing water after cleaning is discharged to the outside of the tank body 101 through the drain pipe 111; in this embodiment, the driving device 114 is a conventional telescopic structure in the prior art, and its structure and function are not elaborated here one by one.

[0040] In some embodiments, the drain pipe 111 is a telescopic pipe, and the bottom end of the drain pipe 111 is fixedly connected to the tank body 101. When the cleaning tray 106 moves upward under the drive of the driving device 114, the drain pipe 111 extends, and when the cleaning tray 106 moves downward under the drive of the driving device 114, the drain pipe 111 contracts.
