Problems solved by technology

[0005] Relying on distilled water cleaning alone cannot achieve the effect of clearing dirt. In this utility model, the scraper installed on the stirring shaft can clean up the residual scaling on the inner wall of the evaporation chamber. It is easy to damage the surface structure of the inner wall, and the residual dirt on the scraper still needs to be cleaned with additional distilled water, and the structure is not reasonable yet

Abstract

The invention discloses a double-effect concentrator. The double-effect concentrator comprises a primary-effect heater, a primary-effect evaporator, a secondary-effect heater and a secondary-effect evaporator, wherein the upper part of the primary-effect evaporator is provided with a first air outlet pipe, the first air outlet pipe is connected with the secondary-effect heater, the upper part of the secondary-effect evaporator is provided with a second air outlet pipe, according to the key point of the technical scheme, the second air outlet pipe is connected with a steam collector, a pressurizing device is arranged in the steam collector, the steam collector is connected with the first air outlet pipe by virtue of a pipeline, valves for controlling the connection are respectively arranged between the steam collector and the first air outlet pipe and between the steam collector and the second air outlet pipe, the first air outlet pipe and the second air outlet pipe are respectively provided with a water spray head. By adopting the double-effect concentrator, dirt in an evaporation chamber can be effectively cleared.

Description

technical field [0001] The present invention relates to a concentrator, more specifically, it relates to a double-effect concentrator. Background technique [0002] The double-effect concentrator adopts two-effect simultaneous evaporation, and the secondary steam is fully utilized, which not only saves the investment of the boiler, but also saves energy consumption. Compared with the single-effect concentrator, the energy consumption is reduced by 50%; the double-effect concentrator adopts external heating and natural circulation Compared with the vacuum negative pressure method, the evaporation speed is fast and the concentration is large. [0003] Scaling is one of the defects of double-effect concentrators. After mixing and concentrating chemicals and solvents, it is easy to generate fouling in the concentrator cavity, which will lead to an increase in the thermal resistance in the concentrator and affect the evaporation efficiency. In severe cases, it may even lead to sh...
