Preparation method of high temperature hot water for industrial use

Abstract

The invention provides a preparation method for industrial high-temperature hot water. A hot water exchange circulation system, an air exchange heating circulation system and a high-temperature water heating pool for cleaning workpieces together achieve circulatory heating of high-temperature hot water, so that preparation of high-temperature hot water used for cleaning machine components in the machine manufacturing industry, the bearing manufacturing industry and other processing procedures is realized to solve the irresolvable technical problems existing in conventional steam boiler heating and electrical heating, energy saving and environmental protection are achieved, the manufacturing cost is lowered and the production quality and the environmental quality are improved.

Description

technical field [0001] The invention relates to a method for preparing high-temperature hot water for industrial use, in particular to the preparation of high-temperature hot water for cleaning parts involved in machine manufacturing, bearing manufacturing and the like. Background technique [0002] At present, there is an insurmountable process in both the manufacturing of machinery and equipment or in the manufacturing of bearings. It is the cleaning of parts before assembly. After various mechanical parts are processed, the parts themselves produce some dirt. It must be cleaned before use. The effective way to clean the dirt is: high temperature water plus alkaline cleaning agent, high temperature water plus acid cleaning agent. Whether it is high-temperature alkaline cleaning or high-temperature acid cleaning, high-temperature hot water is inseparable. Due to the large amount of high-temperature hot water for industrial use and the continuous work all year round, there...

Problems solved by technology

No matter which heating method is used, there are the following disadvantages: 1. Long heating time, serious waste of resources, and high cost; 2. The temperature is not suitable for control, and the water temperature is high and low, which is not conducive to quality stability; 3. The pollution of the steam boiler is serious , which is not conducive to environmental protection; 4. Electric heating consumes a lot of energy and the heating rate is slow; 5. Whether it is electric heating or steam heating, there is high-temperature water vapor evaporating above the cleaning pool, resulting in high ambient temperature and high humidity in the workshop , is not conducive to the health of workers; six, because electric heating and steam heating are carried out in the cleaning pool, the water in the cleaning pool cannot flow, and the dirt in the pool gradually increases during the cleaning of the workpiece, and it cannot be filtered during work. Need to change water continuously, resulting in huge water consumption and cleaning dosage, resulting in serious waste of resources
