Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an evaporator structure. Background Art

[0002] In the chemical production process, evaporators are usually required. Evaporation is a unit operation that uses heating methods to heat a solution containing non-volatile solutes to a boiling state, vaporizes and removes part of the solvent, thereby increasing the solute concentration in the solvent. The vertical evaporator structure not only occupies a small area, but also can greatly improve the tube sheet layout rate, reduce the volume of the heat exchanger, and reduce material costs.

[0003] Publication number "CN215609360U" provides a low-energy vertical evaporator for chemical reactions, which includes a primary evaporation chamber, a secondary evaporation chamber, a steam inlet, a separator, and a concentrated liquid outlet. The primary evaporation chamber and the secondary evaporation chamber are connected in series up and down, the steam inlet is installed on one side of the primary evaporation chamber, the separator is installed on the secondary evaporation chamber, and a concentrated liquid outlet is provided on the separator. Several thermal insulation connection mechanisms are provided between the primary evaporation chamber and the secondary evaporation chamber, and between the secondary evaporation chamber and the separator. The thermal insulation connection mechanisms are used to seal the primary evaporation chamber, the secondary evaporation chamber, and the separator, thereby improving the sealing and thermal insulation properties of the equipment.

[0004] However, the above device still has the following problems during implementation:

[0005] 1. Existing evaporator structures mostly use fixed heating tube bundles and central circulation tubes installed in the heating chamber for heating. The heating tubes cause the solution to boil and the hot gas to rise. Therefore, temperature is one of the key factors affecting evaporation efficiency. The higher the temperature of the liquid, the faster the evaporation rate. Most evaporators cannot accurately estimate the temperature during the liquid evaporation process, lack auxiliary heating processing, and the heating is uneven, which easily leads to low evaporation efficiency.

[0006] 2. Most existing evaporator structures lack a filtering structure. When the evaporator is in use, it absorbs the heat released by the combustion of fuel in the furnace to heat the water to generate steam. When the heat is absorbed, a certain amount of dust will be mixed in, causing the impurities in the pipe wall of the evaporator to adhere heavily, resulting in blockage. Utility Model Content
