specific Embodiment approach 1

[0009] Specific implementation mode 1: Combination figure 1 with figure 2 Explaining this embodiment, the solid particle collection device of the anti-condensation water backflow wet filter of this embodiment includes a sampling pipe 1, a cylindrical fiber particle filter 3, a filter support net 4, and a gas-water separator. The device includes a condensed water support plate 5, a filtered gas pipe 6 and a tapered support 7. The cylindrical fiber particulate filter 3, the filter support net 4 and the gas-water separator are arranged in the sampling pipe 1 from bottom to top, and are cylindrical 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 pipe 1, the condensate support plate 5 is sealed and fixed on the inner wall of the sampling pipe 1, and the condensate support plate 5 There is a central hole 5-1, the lower end of the filtered gas pipe 6 is installed on the condensate support pl...

specific Embodiment approach 2

[0010] Specific implementation manner two: combination figure 1 To illustrate this embodiment, the vertical distance H from the upper port of the filtered gas pipe 6 to the lower edge of the central conical top plate 7-1 is 10 mm to 30 mm. This setting facilitates the collection of condensate. The other composition and connection relationship are the same as in the first embodiment.

specific Embodiment approach 3

[0011] Specific implementation mode three: combination figure 1 To illustrate this embodiment, the outer diameter of the filtered gas pipe 6 in this embodiment is smaller than the lower edge diameter of the central conical top plate 7-1. This setting prevents the backflow of condensate water more effectively. Other components and connection relationships are the same as those in the first or second embodiment.

[0012] The working principle of the present invention: combined Figure 1 to Figure 3 To explain the working principle of the present invention, the solid particle collection device of the anti-condensation water backflow wet filter of the present invention is installed on the sampling gun 9, and the sampling gun 9 is inserted into the gas and solid two-phase fluid pipe or container 10, using The suction pump 11 collects solid particles in the gas and solid two-phase fluid through the suction pipe 2; in the process of sampling industrial gas particles, the gas first ente...

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 condensate backflow soaking a filter. Background technique [0002] The collection of solid particles in gas and solid two-phase fluids involves a wide range of scientific research and production fields, such as thermal power generation, cement, chemical, food and other industries that need to collect solid particles in gas and solid two-phase flows. [0003] The principle of collecting solid particles in gas and solid two-phase flow: The gas and solid two-phase flow enters the collection device, the solid particles are filtered out by the filter, and the filtered pure gas is discharged into the atmosphere through the air extraction device. [0004] For industrial gas, when the temperature of the gas is higher than the temperature of the external environment, condensed water will be generated in the collection device during the process...
