A waste water utilization and flue gas emission reduction system based on solar energy

Abstract

A waste water utilization and flue gas emission reduction system based on solar energy. The single-effect evaporation pool is connected to the entrance of the channel A-A of the high-efficiency winding heat exchanger through the water vapor pipeline; the solar photovoltaic power generation panel is connected to the battery pack and the single-effect The heating pipe in the evaporation pool is connected; there are two-fluid atomizing nozzles and humidity sensors inside the liquid agglomeration chamber. The outlet of the high-temperature dry flue gas pipeline is connected to the inlet of the channel B-B of the high-efficiency winding heat exchanger through the expansion valve, and the outlet of the channel B-B of the high-efficiency winding heat exchanger It is connected to the flue gas inlet; the air compressor is connected to the air inlet of the two-fluid atomizing nozzle, and the liquid inlet of the two-fluid atomizing nozzle is connected to the outlet of channel A-A of the high-efficiency winding heat exchanger through a throttle valve. The system can improve the removal effect of fine particles in flue gas, and can reduce energy consumption in wastewater treatment.

Description

technical field [0001] The invention relates to a waste water utilization and flue gas emission reduction system based on solar energy, and belongs to the technical field of industrial waste gas and waste water treatment. Background technique [0002] At present, in the process of wastewater treatment, multiple-effect evaporators are widely used, and each evaporator in multiple-effect evaporation is called one effect. The evaporator that feeds the heating steam is called the first effect, the evaporator that uses the secondary steam of the first effect as the heating agent is called the second effect, and so on. The purpose of using a multi-effect evaporator is to save the consumption of electric energy for heating, but as the number of effects increases, the utilization rate of steam will decrease and the production capacity of the equipment will decrease. [0003] At the same time, the efficiency of the ESP depends on many factors, including boiler conditions and the elec...
