Flue gas desulphurization water ring vacuum pump outlet gas-liquid separation device

Abstract

A flue gas desulphurization water ring vacuum pump outlet gas-liquid separation device comprises a housing, one side of the housing is provided with an inlet, the inlet is provided with an inlet flange, the other side of the housing is provided with an outlet, and the outlet is provided with an outlet flange; the housing is sequentially divided into a diffusion section, a large internal diameter section and a conflux section from the inlet to the outlet, the internal diameter of the diffusion segment gradually increases from the inlet to the outlet, and the internal diameter of the conflux gradually decreases from the inlet to the outlet; and the bottom of the large internal diameter section is a funnel-shaped liquid collection room, the top liquid inlet of the liquid collection room is provided with a baffle plate bracket, and the baffle plate bracket supports a baffle plate. The device is a two-phase fluid separation device combining baffling separation with settling separation, can effectively separate and collect fine droplets in the two-phase fluid at the outlet of a vacuum pump, can prevent the secondary entrainment of the collected droplets by a gas, and effectively treats the environmental pollution.

Description

technical field [0001] The invention relates to a gas-liquid separation device used in a flue gas desulfurization device of a thermal power plant, in particular to a gas-liquid separation device installed on an outlet pipeline of a water ring vacuum pump. Background technique [0002] The equipment selected for the vacuum belt dehydration negative pressure system in the limestone wet flue gas desulfurization device of the existing thermal power plant is a water ring vacuum pump, and the working environment at the inlet of the water ring vacuum pump is water filtered by filter cloth (low solid slurry). The working environment of the inlet of the water ring vacuum pump has many factors to change, such as the density of the slurry, the air permeability of the filter cloth (mesh number), the working condition of the cyclone, the gap between the sealing belt of the dehydrator, the amount of sealing water, etc., plus the working state of the dehydrator The change of the washing m...
