Description

Evaporator convenient for descaling

Technical Field

The utility model mainly relates to the field of evaporators, in particular to an evaporator convenient for descaling.

Background

Evaporation is the physical process of converting a liquid state into a gaseous state. In general, a vaporizer, i.e. a body in which a liquid substance is converted into a gas state. There are a large number of evaporators in industry, one of which is the evaporator used in refrigeration systems. The evaporator is an important part in four refrigeration parts, and low-temperature condensed liquid passes through the evaporator to exchange heat with outside air, gasify and absorb heat, so that the refrigeration effect is achieved. The evaporator mainly comprises a heating chamber and an evaporating chamber. The heating chamber provides heat required for evaporation to the liquid, causing the liquid to boil and evaporate; the evaporating chamber makes the gas-liquid phase completely separate.

The circulating cooling water of the evaporator contains a large amount of salt substances, corrosion products and various microorganisms, and as the circulating cooling water is not treated, a large amount of calcium-magnesium carbonate scale, algae, microorganism sludge, slime and the like are formed on the water side of the evaporator after the evaporator runs for a period of time, and the scale is firmly attached to the inner surface of a copper pipe, so that heat transfer is deteriorated, circulating pressure is increased, the vacuum degree of a unit is reduced, the running efficiency of the unit is influenced, and large economic loss is caused. Conventional cleaning methods typically employ chemical cleaning-acid cleaning, which is effective for various depositions and saves time compared to mechanical methods. However, chemical cleaning is corrosive to systems and other metal components, is prone to corrosion of equipment lines, and is prone to environmental contamination during discharge.
