Description

Gypsum dehydrator for wet flue gas desulfurization

Technical Field

Background

The flue gas generated by the fire coal of the power plant contains harmful substances such as oxysulfide and the like, and the flue gas can be discharged into the air after desulfurization treatment reaches the standard. The conventional flue gas desulfurization method comprises wet desulfurization, which is mainly realized by spraying desulfurization slurry, typically limestone-gypsum slurry, on flue gas in a desulfurization tower, and the wastewater generated after the wet desulfurization of the flue gas also needs to be treated. At present, the slurry is generally treated by dehydration by a dehydrator to realize solid-liquid separation. Specifically, the slurry is sent to the filter cloth of the vacuum belt dehydrator, the filter cloth is conveyed by a heavy rubber belt, a groove is transversely formed in the rubber belt, a through hole is formed in the middle of the rubber belt, so that liquid can be sucked into a vacuum box, filtrate and air are pumped to a vacuum main pipe at the same time, the filtrate and the air in the vacuum main pipe enter a gas-liquid separator for gas-water separation, the top outlet of the gas-liquid separator is connected with a vacuum pump, and the gas is pumped away by the vacuum pump. The separated filtrate enters a filtrate receiving water tank from an outlet at the bottom of the gas-liquid separator, and the slurry is pumped in vacuum, passes through a filtering part, a cleaning part and a dewatering part to form a qualified filter cake, and is discharged. In the existing slurry treatment site, after gypsum forms a filter cake, the filter cake is generally positioned at a high position, and the blanking of the filter cake also directly falls on the ground from a high position, is piled on the ground and is cleaned. However, this approach has the problem of inconvenient field clutter cleaning. In order to solve the above problems, the prior chinese patent No. 202022179009.7 discloses a desulfurization gypsum dehydrator, which uses a receiving hopper to receive a filter cake and then turns over the receiving hopper to discharge, however, when the dehydrator turns over to discharge, a filter cake conveying structure of the dehydrator is stopped, otherwise, there is still a condition of discharging on the ground, and there is room for improvement.
