specific Embodiment approach 1

[0009] Specific implementation mode one: combine figure 1 and figure 2 Illustrate this embodiment, the solid particle collection device of the anti-condensation water backflow soaking filter of this embodiment comprises sampling pipeline 1, cylindrical fiber particle filter 3, filter support net 4 and gas-water separator, and described gas-water separation The device includes a condensed water support plate 5, a filtered gas pipeline 6 and a conical support 7. The cylindrical fiber particle filter 3, filter holder net 4 and gas-water separator are arranged in the sampling pipeline 1 from bottom to top, and the cylindrical shape The upper end of the fiber filter 3 is placed on the filter support net 4, the filter support net 4 is fixed on the inner wall of the sampling pipeline 1, the condensed water support plate 5 is sealed and fixed on the inner wall of the sampling pipeline 1, and the condensed water support plate 5 is fixed on the inner wall of the sampling pipeline 1. T...

specific Embodiment approach 2

[0010] Specific implementation mode two: combination figure 1 Referring to this embodiment, the vertical distance H from the upper port of the filtered gas pipeline 6 to the lower edge of the central conical top plate 7-1 in this embodiment is 10 mm to 30 mm. Such setting facilitates the collection of condensed water. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0011] Specific implementation mode three: combination figure 1 To describe this embodiment, the outer diameter of the filtered gas pipeline 6 in this embodiment is smaller than the diameter of the lower edge of the central conical top plate 7-1. With such setting, the backflow of condensed water is more effectively prevented. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0012] How the invention works: Combining Figure 1 to Figure 3 Illustrate the working principle of the present invention, install the solid particle collection device of the anti-condensation water backflow soaking filter of the present invention on the sampling gun 9, insert the sampling gun 9 in the pipeline or container 10 of gas and solid two-phase fluid, utilize The suction pump 11 collects the solid particles in the gas-solid two-phase fluid through the suction pipe 2; in the process of sampling the particles of the industrial gas, the gas first enters th...

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...
