Disposable antiscaling water heater

Abstract

The invention relates to a water heater, in particular to a disposable antiscaling water heater with energy conservation and environmental protection, comprising a heat exchange generating pond and a heat exchanger, wherein the heat exchanger is arranged in the heat exchange generating pond and comprises a plurality of heat exchange pipes which are arranged into groups in parallel at interval, an upper baffle plate and a lower baffle plate connected with each heat exchange pipe are arranged in the heat exchange generating pond, a cover plate is arranged at the top surface of the heat exchange generating pond. The water heater recycles the heat of the waste hot solution, heat the water for the production, saves the energy sources, reduces the production cost; the waste solution is discharged at lower temperature, being beneficial to the environmental protection and eliminating the cooling process in the subsequent processing; the device has simple structure, and no obstruction, each heat exchange pipe is made of stainless steel and the surface of the outer pipe wall is polished, achieving the wash-free and antiscaling function, and the heat transfer efficiency is high, the operation cost id cheap and the operation is simple because of the characteristic of stainless steel, the popularization and application value is high.

Description

technical field [0001] The invention relates to a hot water generator, in particular to an energy-saving and environment-friendly non-cleaning and anti-scaling hot water generator. Background technique [0002] At present, most printing and dyeing enterprises have to use steam to heat a large amount of clean water in the dyeing machine to print and dye fibers in the production process, which consumes a lot of energy. At the same time, a large amount of printing and dyeing wastewater must be discharged, and the water temperature of these printing and dyeing wastewater is generally 60°C to 90°C, or even higher. Some processes require high-temperature discharge of printing and dyeing products, and the temperature of the discharged wastewater is as high as 120°C. If these waste water are directly discharged without recycling, it will cause great waste of energy. However, using the waste heat of the waste hot water discharged from printing and dyeing to generate process hot wat...
