Wastewater recycling system for cyclone dust removal tower

Abstract

The invention provides a wastewater recycling system for a cyclone dust removal tower, and belongs to a water recycling technology. The system comprises a primary sedimentation tank, a secondary sedimentation tank and a tertiary sedimentation tank which are arranged at the bottom of a dust removal tower. A primary filtering device is arranged between the primary sedimentation tank and the secondary sedimentation tank. A secondary filtering device is arranged between the secondary sedimentation tank and the tertiary sedimentation tank. Under the condition that the existing structure of the existing cyclone dust removal tower is not changed, a wastewater recycling system is added. The system is improved by wet dust removal compared with an original circulating water pump, and the rear-end water of the system automatically flows to a water tank of a cyclone tower by virtue of gravity to be reused, the consumption of water resources can be reduced, and power facilities are not additionallyarranged.

Description

technical field [0001] The invention belongs to the technology of water recycling and reuse, in particular to a wastewater recycling system for a cyclone dedusting tower. Background technique [0002] Wet dust removal technology, also called washing dust removal technology, is a technology that uses water (or other liquids) to contact each other with dusty gas, accompanied by heat and mass transfer, and separates dust particles from gas after washing. Wet dedusting is to make the exhaust gas come into close contact with liquid (usually water) to separate the pollutants from the exhaust gas. It can not only purify the solid particle pollutants in the exhaust gas, but also remove the gaseous pollutants, and at the same time, it can also play a role in cooling the gas. Its advantages are: simple structure, low cost, high purification efficiency, suitable for purifying non-fibrous and various dusts that do not chemically interact with water, especially suitable for purifying hi...

AI Technical Summary

Problems solved by technology

The disadvantages are: pipeline equipment must be anti-corrosion, sewage sludge must be treated, flue gas lift height is reduced, chimney will produce condensed water in winter, etc.

[0004] With the widespread use of cyclone dedusting towers, new environmental pressures have also been brought. Some factories lack wastewater treatment devices and directly drain the wastewater in the cyclone dedusting towers. This wastes a lot of water and pollutes the environment. In the existing technology, there is a lack of waste water purification and reuse system for the cyclone dedusting tower
