Embodiment Construction

[0020] Such as figure 1 As shown, the flue gas and spark extinguishing device of the present invention is composed of a housing 1 and two orifice plates 2 . The shell is cylindrical and arranged horizontally, and it is composed of a straight section and a cone section. The inlet of the flue gas is at one end of the straight section, and the outlet of the flue gas is at one end of the cone section. The outlet of the cone section adopts a gradual design to reduce the local smoke resistance. The inner wall of the straight section of the housing 1 is provided with a slot 5, and the slot is formed by two splints welded to the inner wall of the housing. The orifice plate 2 is vertically inserted between the two splints in the slot 5 to facilitate the installation of the orifice plate. The orifice plate is made of high temperature resistant metal material, and the plane of the orifice plate 2 is perpendicular to the axial direction of the shell 1 . In addition to the vertical set...

Abstract

The invention discloses a fire extinguishing device for biomass flue gas. The device comprises a cylindrical housing with a flue gas inlet and a flue gas outlet, and at least one orifice plate and is arranged in the cylindrical housing, wherein separation blades are arranged around the through holes. Compared with the prior arts, the device has orifice plates with a special fish scale-type structure, thus when biomass flue gas is fed into the device, burning particles in biomass flue gas fall to a housing bottom of the device after impacting separation blades of the orifice plates. Through the device, movement loci of burning particles are changed because of a baffling effect produced by two filtering processes of the two orifice plates, and the advantages of good burning particle gathering effect, low flue gas pressure drop and no pipe blockage are realized.

Description

technical field [0001] The invention belongs to the field of fire extinguishers, in particular to a device for extinguishing sparks in biomass flue gas. Background technique [0002] During the use of various kilns, hot blast stoves and boilers, due to factors such as incomplete combustion or unreasonable flue design, some sparks (unburned particles) will inevitably be contained in the biomass flue gas. When the flue gas containing Mars enters the lower-level equipment, it will cause abnormal re-ignition and form a safety hazard. In severe cases, it will cause damage to the equipment or cause an explosion accident, affecting normal production. Existing extinguishing device, such as in automobile exhaust emission, fire shield is a kind of device commonly used, and it allows airflow to pass through, and can stop flame and spark in the exhaust flow, but does not have the function of stopping particle. The spark-containing dust produced in industrial production can be filtered ...
