Steam-water heat exchange unit

Technical Field

The utility model relates to a heat exchanger technical field specifically is a soda heat exchanger group.

Background

A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, and is also called a heat exchanger. The heat exchanger can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in chemical production, and is more widely applied. There are many types of heat exchangers, but the heat exchange principle and the heat exchange mode of cold and hot fluids can be basically divided into three main categories: the plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes, thin rectangular channels are formed among various sheets, and heat exchange is carried out through the sheets. The plate heat exchanger is ideal equipment for carrying out heat exchange between liquid and between liquid and steam; the traditional heat exchanger unit is large in size, low in heat exchange rate, large in heat loss and short in service life, so that a heat exchanger is needed in the market, and has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application, long service life and the like.
