Deslagging device of venturi cyclone dust collector

Abstract

The invention discloses a deslagging device of a venturi cyclone dust collector. The deslagging device is suitable for the venturi cyclone dust collector to collect slag particles and discharge drossin a slurry pool, and mainly comprises a funnel, a gate valve, a slag liquid tank and a blow-down valve; the funnel is composed of a cuboid and a prismoid structure, and is arranged at the rear end ofa venturi tube diffusion section, the gate valve is arranged on a pipeline behind a slag outlet of the funnel, the slag liquid tank is of a cuboid structure and is used for temporarily storing slag liquid, and the blow-down valve is arranged on a pipeline behind a sewage outlet of the slag liquid tank. The device has the effects that after waste gas passes through the venturi tube, a gas-liquid mixture falls into the funnel, precipitable particle pollutants freely settle in the funnel, and dross difficult to precipitate floats in the cuboid of the funnel; the deslagging device maintains a certain water level, scouring of a gas mixture to the pipeline is reduced, and the service life of the pipeline is prolonged; dross can be led into the deslagging device to be discharged by raising the water level of the slurry pool.

Description

technical field [0001] The invention belongs to the technical field of Venturi cyclone dust collectors, in particular to a slag removal device of Venturi cyclone dust collectors. Background technique [0002] Venturi cyclone dust collector is a wet dust collector, combining the functions of venturi tube and cyclone dust collector, it has the characteristics of high-efficiency dust removal, which can effectively remove liquid or solid particles from the air flow, and at the same time, remove gaseous pollutants. [0003] When the venturi cyclone dust collector is used in the crude gas upgrading process, there is often a phenomenon that it is necessary to clean up the slag. After the gas and liquid are mixed in the venturi tube, the particle pollutants in the gas will form particles with some tar and the tar block will float in the slurry. On the surface of the pool, due to the high sealing requirements, it is difficult to clean the slag. Contents of the invention [0004] T...
