Anti-scaling heat exchanger

Technical Field

The utility model relates to a shell and tube heat exchanger prevents scale deposit technical field, concretely relates to prevent scale deposit heat exchanger.

Background

The shell and tube heat exchanger is the most widely used heat exchanger in chemical industry and alcohol production. It is mainly composed of a shell, a tube plate, a heat exchange tube, a seal head, a baffle plate and the like. The required material can be respectively made of common carbon steel, red copper or stainless steel. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket, flows in the pipe and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side.

The existing tube type heat exchanger can generate a scaling phenomenon in a heat exchange tube due to water quality of part of regions, and the scaling phenomenon in the tube is not controlled during operation, so that the end difference of a condenser is increased, the vacuum degree is reduced, and the maintenance cost is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent heat exchanger that scales, the shell and tube heat exchanger who has solved present waste heat power generation project leads to condenser end difference to rise and the technical problem that the vacuum descends because of the incrustation phenomenon appears in the quality of water reason heat exchange tube. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an anti-fouling heat exchanger, wherein:
