Problems solved by technology

The disadvantage is that the working range of the heater is limited in principle, and it can only operate within a certain concentration range. If it exceeds a certain concentration, scaling on the heating surface of the tube side is inevitable.
[0009] Second, whether it is a forced circulation heater or a heater operated by other methods such as falling film or rising film, there will be a problem of fouling inside the tube if the material concentration exceeds a certain level
[0010] Third, the evaporator in the form of a forced circulation heater still has a problem of requiring an evaporation chamber. After heating, the superheated material needs to enter a relatively low-pressure evaporation chamber for flash evaporation to complete a concentration step. After several consecutive such steps, To achieve the purpose of concentration
The existence of the evaporation chamber makes the whole device very large and complicated, and at the same time increases the manufacturing cost of the device

Abstract

The invention discloses a single-end-face heat pipe anti-scaling evaporator. The evaporator comprises a shell, a heat conduction pipe, a first end face, a second end face, a descaling unit and a support. The shell comprises a cylindrical shell body, a first cover body and a second cover body, the first cover body and the second cover body are fixedly installed on the upper end face and the lower end face of the cylindrical shell body through flanges respectively, the first end face is located between the first cover body and the upper end face of the cylindrical shell body, and the second endface is located between the second cover body and the lower end face of the cylindrical shell body. One end of the heat conduction pipe is closed and the other end is open. The open end of the heat conduction pipe is welded to the hole of the second end face. The evaporator has the beneficial effects that scaling accumulation is effectively avoided, shutdown maintenance caused by descaling is avoided, equipment maintenance is reduced, and the productivity is improved, due to the design of the scale scraping device, on one hand, scales on the heat conduction pipe are effectively scraped, the steam crystallization process is accelerated in the up-down reciprocating motion process, the productivity is effectively improved, energy is saved, and the evaporator is simple in structure, free of manufacturing dead angles and easy and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of evaporators, in particular to an anti-fouling evaporator with a single-end heat pipe. Background technique [0002] At present, in the environmental protection industry, high-salt wastewater and landfill leachate will require reliable concentration equipment in the later stages of treatment. The existing concentration equipment basically uses double-effect, triple-effect, and MVR equipment to concentrate and reduce the amount of materials. [0003] The specific method of enrichment work of double-effect, triple-effect and MVR equipment is as follows: [0004] The double-effect evaporator generally adopts the external circulation heater method. [0005] The three-effect evaporator generally adopts the external circulation heater method. [0006] The MVR evaporator includes: external circulation heater, flash tank, crystallization tank, circulation pipeline, circulation pump, secondary steam pipeline, ste...
