Desulfurization wastewater sludge-water mixing device

Abstract

The invention provides a desulfurization wastewater sludge-water mixing device, belonging to the technical field of desulfurization wastewater treatment. The device comprises a wastewater inlet, a sludge discharge port, a supernate discharge port, a gypsum separator and a gypsum pumping outlet, wherein the wastewater inlet is positioned on the top of the device; the sludge discharge port is positioned on the bottom of the device; the supernate discharge port is positioned on the upper part of the side surface of the device; the gypsum separator is positioned at the back part of the sludge discharge pump; and the gypsum pumping outlet is positioned on the lower part of the side surface of the device. The desulfurization wastewater enters the device from the wastewater inlet, the supernate in the device is sent to a concentrating tower by the discharge pump, and the settled sludge is sent to a concentrated water tank by the sludge discharge pump so as to be mixed; and after the wastewater is subjected to clarification treatment, the supernate is sent to the concentrating tower, and at this time, the lower sludge water is subjected to gypsum separation treatment by the gypsum separator. The device is simple in structure, so that the problem of sludge treatment caused by wet desulphurization of the coal-fired power plant can be easily solved.

Description

technical field [0001] The invention relates to the technical field of desulfurization waste water treatment, in particular to a desulfurization waste cement water mixing device. Background technique [0002] With the gradual deepening of the country's understanding of atmospheric and water environmental protection, the requirements for sulfur dioxide emission standards for large-scale industrial flue gas such as coal-fired power plants have become increasingly stringent, and wet desulfurization technology has been widely recognized and applied in the industry. In recent years, with the further tightening of air pollutant emission standards, ultra-clean emission transformation has been implemented in coal-fired power plants in key areas, and high-efficiency wet desulfurization technology has become the main technology for removing sulfur dioxide in flue gas. While thermal power plants are focusing on reducing the concentration of air pollutants, the issue of wastewater disch...
