1results about How to "Reasonable recycling" patented technology

The application provides an industrial waste heat recovery and utilization system with high efficiency and energy saving, comprising a boiler, a periodic blowdown tank connected with the boiler, a periodic blowdown expander communicated with the periodic blowdown tank through a blowdown pipe, wherein the blowdown pipe is provided with a first primary valve and a first secondary valve, a steam drum, a continuous blowdown tank communicated with the steam drum through desalted water branch pipes arranged on the left and right sides of the steam drum, a continuous blowdown expander communicated with the continuous blowdown tank through a desalted water main pipe, and a heat exchange station water supply tank communicated with the continuous blowdown expander through a heat exchange station branch pipe. The periodic blowdown expander and the continuous blowdown expander are arranged to receive waste heat water from periodic blowdown of the boiler and desalted water from continuous blowdown of the steam drum respectively, and the flow of the waste heat water and the desalted water is controlled through valves, so that more reasonable recycling and discharge can be realized, water consumption and wastewater discharge can be effectively reduced, the utilization efficiency of energy is improved, energy waste is reduced, the operation cost of enterprises is reduced, and the goal of energy saving and emission reduction is achieved.
