Solid particle collecting device of anti-condensation water backflow soaking filter

Abstract

The invention discloses a solid particle collecting device of an anti-condensation water backflow soaking filter, relates to solid particle collecting devices, and aims to solve the problem that condensation water soaks the filter in a gas and solid two-phase solid particle collecting process. A cylindrical fiber particle filter, a filter tray net and a gas and water separator are arranged in a sampling pipe from bottom to top; the upper end of the cylindrical fiber filter is arranged on the filter tray net; the filter tray net is fixed on the inner wall of the sampling pipe; a condensation water tray plate is hermetically fixed on the inner wall of the sampling pipe; after filtration, the lower end of a gas pipe is arranged on the condensation water tray plate; after filtration, the lower port of the gas pipe corresponds to a central hole; a conical bracket is arranged above the gas pipe after filtration; the conical bracket comprises a central conical top plate and a plurality of supporting ribs; and the central conical top plate is arranged on the inner wall of the sampling pipe through the plurality of supporting ribs. The invention is applied to the collection of solid particles in industrial waste gas and industrial process gas.

Description

technical field [0001] The invention relates to a solid particle collection device, in particular to a solid particle collection device for preventing condensed water from flowing back and soaking a filter. Background technique [0002] The collection of solid particles in gas-solid two-phase fluid involves a wide range of scientific research and production fields, such as: thermal power generation, cement, chemical industry, food and other industries that need to collect solid particles in gas-solid two-phase flow. [0003] The principle of solid particle collection in gas-solid two-phase flow: the gas-solid two-phase flow enters the collection device, and the solid particle particles are filtered out by the filter, and the filtered pure gas is discharged into the atmosphere through the suction device. [0004] For industrial gas, when the gas temperature is higher than the external ambient temperature, condensed water will be generated in the collection device during the c...
