Embodiment Construction

[0015] The reclaimed water reuse device of the present invention includes a reclaimed water treatment device, a reclaimed water supply device and a high-temperature flue gas cooling device connected in sequence, the reclaimed water supply device supplies reclaimed water from above the high-temperature flue gas cooling device, and the reclaimed water to be cooled The high-temperature flue gas is fed from the top of the cooling device, and the reclaimed water exchanges heat with the high-temperature flue gas, thereby cooling the high-temperature flue gas. After cooling, the high-temperature flue gas flows from the lower part of the cooling device discharge.

[0016] The following will refer to figure 1 with figure 2 The reclaimed water recycling device of the present invention will be described in detail.

Abstract

The invention provides a reclaimed water reuse device. The device comprises a reclaimed water treatment unit, a reclaimed water supply unit and a high-temperature flue gas cooling unit which are connected in sequence. The reclaimed water supply device supplies reclaimed water from the top of the high-temperature flue gas cooling unit, to-be-cooled high-temperature flue gas is charged from the upper part of the high-temperature flue gas cooling unit, the reclaimed water and the high-temperature flue gas exchange heat to thereby cool the high-temperature flue gas, and the cooled high-temperature flue gas is discharged from the lower part of the high-temperature flue gas cooling unit. The inventive device can be used for a high-temperature flue gas cooling process in treatment of hazardous wastes, and has no influence to the high-temperature flue gas cooling process. The indices of the discharged gas meet the discharge requirement, and the consumption of softened water is reduced by 40 t every day.

Description

technical field [0001] The invention relates to a middle water recycling device and the application of the middle water recycling device in hazardous waste treatment. Background technique [0002] Reclaimed water, also known as reclaimed water, refers to water that can be used beneficially after proper treatment to meet certain water quality indicators and meet certain use requirements. With the increasing development of industry, the use of water resources is gradually increasing. The sustainable use of limited water resources and the realization of a virtuous cycle of water ecology are important goals of industrialized society. At the same time, the amount of production wastewater generated in industrial production is large, and the treatment cost is high. Therefore, the production wastewater will be treated to a certain extent and continue to be used, which not only saves water resources but also saves the cost of sewage treatment, which has good social and economic bene...
