Horizontal evaporative concentration system

Abstract

The invention provides a horizontal evaporative concentration system, comprising an evaporative concentration unit, a gas-liquid separator, wherein, the evaporative concentration unit comprises a water supply pipe, a drug supply pipe, a horizontal rotating barrel, a cooling bin, a separating bin, a spiral delivery part, a driving part which drives the horizontal rotating barrel to rotate, and a heating part which heats the horizontal rotating barrel. The water supply pipe and the drug supply pipe respectively supply raw water and medicaments to the horizontal rotating barrel, the cooling bin is connected with the horizontal rotating barrel and the separating bin and arranged between the horizontal rotating barrel and the separating bin, the spiral delivery part passes through the horizontal rotating barrel and extends to the separating bin, and the separating bin is communicated with the gas-liquid separator. The invention has the advantage of simple structure. According to the invention, raw water can rapidly and continuously make steam and crystallized products, the steam and crystallized products can be separated completely in the separating bin; the whole process has no need of extra pipelines, the phenomenon of pipe blockage is avoided, and even the pipe blockage occurs, the blockage position is easy to be found; in addition, no problem of pipe returning evaporation exists, and the problem of pollution caused by returning evaporation is avoided.

Description

technical field [0001] The invention relates to a horizontal evaporation concentration system. Background technique [0002] In the existing wastewater evaporation and concentration production, vertical multi-effect evaporation and concentration are generally used. The vertical multi-effect evaporation and concentration device raises the temperature of the 1-effect wastewater through the hot blast stove, and then increases the evaporation area through hundreds of vertically arranged tubes in the 2, 3 and 4 effect evaporators, and in the negative Under the condition of high pressure, the evaporation of water is completed, and the purpose of wastewater concentration is achieved. [0003] The vertical multi-effect evaporation and concentration process has the following problems: [0004] 1. It covers a large area and costs a lot. The price of a set of vertical evaporation and concentration systems is generally close to 10 million yuan, and it covers a large area, generally a...

[0005] 2. Difficulty in maintenance

In addition, because there are many and very thin pipes, it is difficult to find and clear them, resulting in a long maintenance cycle and affecting wastewater treatment

[0006] 3. The pipe is easy to leak and difficult to repair

During the repair process, it is difficult to identify the leaking pipe, resulting in a long time-consuming and difficult repair

Although it is possible to seal a part of the tube, after a period of use, the evaporation area will be greatly reduced, and the evaporation effic
