Problems solved by technology
Problems existing in the existing feasible technology: The energy consumption of sewage treatment in a power plant accounts for 19.48% of the total power consumption of the whole plant
Sewage treatment has problems such as large floor area, difficult sludge treatment, complex treatment equipment and methods, long process and high energy consumption.
[0008] In short, flue gas dust removal, desulfurization, and denitrification up to standard emissions require additional equipment and expensive operating costs; sewage treatment requires additional large-scale sewage treatment devices and expensive operating costs, especially the generated sludge will cause secondary pollution, and consume a lot of oxygen

Embodiment Construction
[0022] like figure 1 As shown, the industrial furnace 4 can also be a reactor that produces flue gas, such as the catalytic cracking reactor in the oil refining process, etc., and the high-temperature flue gas produced passes through the waste heat recovery and utilization system 3 for waste heat recovery. Due to the composition of the flue gas The dew point and heat transfer thermodynamic problems make the temperature of the flue gas have a relatively high temperature, generally around 150°C, and some are even higher. The flue gas is transported to the flue gas extraction sewage distillation tower system 1 by the flue gas blower 2 The bottom of the distillation tower; sewage will be produced during the operation of the industrial equipment in the industrial equipment area 5, and the sewage collection system 13 in the equipment area will collect the sewage produced in the equipment area, and the sewage will be transported to the sewage pool system 10 along the pipe network of t...

The invention relates to a clean production industrial zero discharge method. The method utilizes flue gas heat for gas stripping of distillation sewage, and still can distill rainwater in the existence of remaining heat. The method not only can wash out the dust, toxic substances and harmful gas in industrial furnace flue gas, but also can wash out harmful substances in industrial furnace flue gas or dissolve the harmful substances in various components of the sewage to carry out reaction so as to generate new substances, by distillation, various fractions in the sewage are distilled out, various substances in industrial furnace flue gas and sewage can be recycled, environmental pollution is reduced, industrial furnace flue gas desulfurization, denitration and dust removal devices are eliminated, no sludge problem exists, the industrial equipment operation cost is lowered, and comprehensive utilization of all process exhaust gas can be realized.
Description
technical field [0001] The invention relates to an industrial zero discharge method for clean production, which is widely used in various industrial fields and belongs to the fields of clean production, energy saving, water saving, emission reduction and environmental protection. Background technique [0002] Industrial furnace flue gas (including industrial high-temperature tail gas) widely exists in various industries such as coal chemical industry, petroleum and petrochemical industry, chemical industry, electric power, metallurgy, building materials, leather, ceramics, papermaking, medicine, printing and dyeing, textile and food processing. Oil-rich coal has made coal chemical industry increasingly a national strategy. The current treatment methods for industrial furnace flue gas are waste heat recovery, dust removal, desulfurization, and denitrification, followed by heating and emission. Coal power flue gas pollutants are roughly divided into gaseous pollutants (SOx and N...
