Problems solved by technology

[0005] In order to prevent fouling of the evaporative concentration system, the existing technology mainly uses chemical methods to remove calcium, magnesium and silicon in water. Common agents are sodium hydroxide, sodium carbonate, magnesium salt, etc. These agents consume a lot and are expensive. The solution produces a large amount of solid waste, which increases the operating cost of industrial production and the cost of environmental protection

Embodiment example

[0056] This technology was used in a mineral processing lye concentration recovery device, and the heat exchanger was opened before and after application to observe its fouling. Before adopting this technology, when the evaporative concentration device operated continuously for 40 days, the evaporation capacity decreased significantly, and the evaporative concentration could no longer operate normally, so it was necessary to stop the machine and open the heat exchanger for mechanical cleaning. Open the heat exchanger and observe. It can be seen that the wall surface of the heating tube of the heat exchanger is seriously scaled. The thickness of the scale layer is 3-5mm, and some tubes are blocked. Obviously, the decrease in evaporation is caused by the formation of scale. The result is a significant reduction in heat transfer efficiency. Using a new type of evaporative concentrator, when the device runs continuously for 120 days, the evaporation capacity does not decrease sign...

Abstract

The invention relates to a mechanical-assisted self-cleaning evaporation concentrator and an evaporation concentration method. The mechanical-assisted self-cleaning evaporation concentrator comprisesan evaporation tank, a circulating pump, a shell-and-tube heat exchanger, a particle circulating pipe, a feed liquid circulating pipe, a particle adjusting valve, a guide cylinder, a reflux cylinder and a vapor-liquid separator. According to the invention, the scaling problem in the production and operation of the evaporation and concentration device is fundamentally solved, so that the evaporation and concentration device is free of scaling and pollution blockage in the operation process, and the efficient and energy-saving operation of the evaporation and concentration device is maintained.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a mechanically assisted self-cleaning evaporation concentrator and an evaporation concentration method. Background technique [0002] In my country's chemical industry, metallurgy, food and beverage, pharmaceutical and other fields, evaporation equipment, as a common equipment, is widely used. The evaporation and concentration device heats the solvent-containing material solution through thermal energy (steam, electric energy, etc.), so that a part of the solvent evaporates in the form of vapor, and finally obtains a physical process of thick material. [0003] Evaporation and concentration equipment is widely used in the field of aqueous solutions containing inorganic salts and organic salts. The ultimate goal is to achieve the concentration of water-containing materials. In the actual operation of evaporation and concentration equipment in my country, the biggest problem is sc...
