Example Embodiment

[0027] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0028] figure 1 It is a schematic structural diagram of an embodiment of the present invention. Such as figure 1 As shown, the solid / gas separation device with anti-flammability and anti-scalding filter material in this embodiment includes a primary separation structure 24, a cooling and fire-stopping structure 25, an inert gas fluidized injection structure 26, and a fine filtering structure 27.

[0029] The primary separation structure 24 includes a solid / cyclone separation section 16 and an ash hopper 18.

[0030] The solid / gas cyclone separation section 16 mainly functions to perform solid / gas preliminary separation and sedimentation treatment for dust-containing gas. A dust-containing air inlet 15 is provided on the side wall of the solid / cyclone separation section 16. The dust-containing airflow inlet 15 is connected to the side wall of the solid / cyclone separat...

Abstract

The invention relates to a solid/gas separation device with deflagration prevention and filter material burning prevention functions and a working method. The solid/gas separation device comprises a primary separation structure, an ash bucket for receiving solid substances is mounted at the lower end of the primary separation structure; the upper end of the primary separation structure is providedwith a cooling fire-retardant structure for cooling gaseous substances; an inert gas fluidization blowing structure is mounted at the bottom of the ash bucket and comprises a plurality of inert gas fluidization blowing devices with upward nozzles. According to the invention, a pneumatic conveying system is ensured to be applied to conveying of high-temperature fly ash containing CO gas and H2 gasor prone to spontaneous combustion, so that deflagration accidents and filter material burning accidents are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a solid / gas separation device with anti-explosion and anti-burning filter materials. Background technique [0002] In chemical industry, petroleum, metallurgy, electric power and other industries, high temperature dusty gas is often produced. Due to different process needs, energy recovery requirements or to meet environmental protection emission standards, these high-temperature dusty gases need to be dedusted. In order to reduce the burden on operators, prevent secondary pollution caused by the high-temperature ash collected by the dust removal device, and avoid safety accidents (high-temperature ash often contains toxic gases such as gas, and high-temperature ash is easy to come into contact with air, so it is prone to safety accidents) , More and more high-temperature dust removal ash is transported by pneumatic conveying process (including negativ...
