Description

Technical Field

[0001] The utility model relates to the field of evaporation tower bodies, in particular to a low-temperature carrier gas evaporation spray cleaning device. Background Art

[0002] The working principle of the carrier gas low-temperature evaporation equipment is a new type of evaporation technology that uses the difference in saturated vapor pressure of water molecules in the air at different temperatures as the mass transfer power. The PDS evaporation equipment is mainly composed of a tower body, a heat exchange unit, a fluid conveying and cooling system, and operates in a continuous feeding and discharging and fully automatic control mode, which basically realizes unattended operation;

[0003] After many macromolecular organic substances are concentrated under high temperature and vacuum, their viscosity increases; and calcium and magnesium ions in wastewater are also prone to scaling under high temperature conditions; dissolved inorganic salts will form crystals on the contact surface of the equipment after supersaturation; these reasons often cause scaling in the low-temperature carrier gas evaporation tower or blockage at the outlet, which is often manifested in blockage of tower packing, scaling and agglomeration at the bottom of the tower cone, blockage of the discharge port, etc. The adverse effects on low-temperature evaporation are manifested in reduced gas-liquid heat transfer efficiency, difficulty in discharging concentrated liquid, deformation caused by uneven heating of the tower, etc., which ultimately greatly weaken the evaporation and concentration effect, and even require replacement of packing and disassembly of the tower to clear, affecting the normal operation of the process. The low-temperature carrier gas evaporation tower is usually cleared and descaled or the packing is replaced, which usually requires the tower to be disassembled as a whole, causing the entire process to stop running and affecting normal production. Therefore, a low-temperature carrier gas evaporation tower spray cleaning device is set up to reduce the manpower and material costs of tower disassembly and cleaning without affecting the normal operation of the overall process, and reduce the adverse effects of low-temperature carrier gas evaporation on production. This is of great significance.

[0004] Therefore, it is necessary to invent a low-temperature carrier gas evaporation spray cleaning device. Summary of the invention

[0005] To this end, the utility model provides a low-temperature carrier gas evaporation spray cleaning device. When in use, the feed valve and the discharge valve are closed, and the water inlet valve and the water outlet valve are opened at the same time, and the high-pressure cleaning water pump is started to transport the cleaning liquid in the cleaning water tank through the water inlet pipe to the inside of the evaporation tower body for high-pressure flushing, so as to solve the problems in the background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-temperature carrier gas evaporation spray cleaning device, comprising an evaporation tower body, the top of the evaporation tower body is provided with a feed pipe and a water inlet pipe, the bottom of the evaporation tower body is provided with a discharge pipe and a water outlet pipe, one end of the water outlet pipe is fixedly connected to a cleaning water tank, a high-pressure cleaning water pump is installed on the cleaning water tank, the output end of the high-pressure cleaning water pump is connected to the water inlet pipe, the water inlet pipe is provided with a water inlet valve, the feed pipe is provided with a feed valve, the discharge pipe is provided with a discharge valve, and the water outlet pipe is provided with a water outlet valve.
