Problems solved by technology

The former needs to consume a large amount of coal resources, exacerbating the deterioration of my country's energy structure and environmental pollution; although the latter is relatively clean, the energy it obtains is closely related to weather conditions such as four seasons, day and night, and cloudy and sunny days, resulting in fluctuations in power generation

Abstract

The invention relates to a high salt-bearing wastewater treatment process with an efficient combination steam source. In the high salt-bearing wastewater treatment process, the steam source in the evaporative crystallization procedure comprises a solar steam boiler and a fuel steam boiler which are used for adjusting the steam supplying amount and the steam supplying proportion through steam adjusting equipment. By the adoption of the high salt-bearing wastewater treatment process, energy consumption is lowered, and environmental pollution is effectively avoided; meanwhile, the situations that photoelectric heating efficiency is low and up-down fluctuation and instability happen are avoided, the electric storage condition in a common heat source power generation technology is avoided, solar energy and common fuel are reasonably used together, and thus the process can save more energy and is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a high-salt wastewater treatment process with a high-efficiency combined steam source. Background technique [0002] At present, more than 50% of the fossil energy consumed by humans is to obtain industrial steam, which is used as a heat source for industrial production or later wastewater treatment. The conventional heat source utilization process mostly uses fuel (coal gas, natural gas, biogas, oil, coal, etc.) to boil the water in the boiler to generate high-pressure steam, which is used to drive the steam engine to run, and the steam engine drives the generator to generate electricity. After power generation, the low-pressure steam or The high-pressure steam produced can also be used as a heat source for industrial production. The whole process needs to consume a large amount of fuel, which not only aggravates the waste of resources, but also aggravates the dete...
