Raw water preheater is a device used for heating raw water, mainly used for heat exchange processes in industrial production. According to different classification standards, raw water preheaters can be divided into the following categories:
1. Classification of heat exchanger types: According to the working principle and structural characteristics of heat exchangers, raw water preheaters can be divided into shell and tube heat exchangers, plate heat exchangers, spiral plate heat exchangers, etc. Among them, shell and tube heat exchanger is the most common type, which consists of a shell and a tube bundle. Raw water flows in the tube bundle and is heated through heat conduction on both sides of the shell and tube.
2. Classification of heating media: According to the different heating media, the raw water preheater can be divided into steam preheater, hot water preheater, etc. A steam preheater uses high-temperature and high-pressure steam as the heating medium to heat the raw water through heat exchange with the raw water; A hot water preheater uses hot water as the heating medium.
3. Functional classification: According to the function and purpose of the raw water preheater, it can be divided into heating type raw water preheater and cooling type raw water preheater. The heated raw water preheater is used to heat the raw water to a certain temperature to meet the requirements of subsequent processes or equipment; The cooling type raw water preheater cools the raw water to a certain temperature to reduce its temperature.
