Description

The invention relates to a technique for cleaning gases from mechanical impurities in the form of dust, particles of soil, metal, smoke, ash, soot, etc. and can be used in industries of building materials, chemical, food, metallurgical, etc., in particular, in systems for cleaning the air flow from the suspended particles of dust and impurities in it.

A device for cleaning gas from mechanical impurities is known, including a cyclone, a gas separator, in the cylindrical housing of which impellers are installed on the drive shaft from the inlet and outlet nozzles, guide vanes are located in the inlet nozzle to control the volume of incoming air, and in the outlet nozzle there is an annular pocket for collecting impurities connected to the inlet of the cyclone and a flue for returning purified air from the cyclone to the gas separator (Information sheet 74.1 Supercyclophan®, http: //www.cimbria. com / files / filer / solutions_en / drying / fans / 74.1_Super_Cyclofan.pdf,)

In the known device, the impeller drive is placed on the gas separator body, which increases its dimensions; the presence of a recovery impeller in the outlet pipe of the gas separator and the drive shaft inside the gas separator housing on which it is located not only complicates the design, but also limits the ability to create internal pressure. The maximum achievable working pressure inside the gas separator is 75 mm, water. Art. (735 Pa), which does not allow to intensify the cleaning process.

The objective of the utility model is to simplify the design and intensify the cleaning process.

EFFECT: increased cleaning efficiency due to increased pressure inside the gas separator.

The technical result is achieved in that in a device for purifying gas from mechanical impurities, including a cyclone, a gas separator, in the housing of which guide vanes, a fan impeller are located at the inlet, an annular pocket in the outlet pipe connected to the inlet pipe of the cyclone, and a gas duct for returning purified air from a cyclone to a gas separator, guide vanes are mounted on a shell fixed inside the housing, and the fan motor is located inside the shell and its shaft is directly connected to the impeller.

In this case, the guide vanes can be mounted rotatably.

In FIG. 1 shows a device for cleaning gas from mechanical impurities; in FIG. 2 - ZD model of a gas separator.

A device for purifying gas from mechanical impurities contains a cyclone 1, a gas separator 2 and a gas duct 3 in the form of a pipeline connecting the outlet pipe 4 of the cyclone with the inlet pipe 5 of the gas separator. At the entrance to the cylindrical body of the gas separator 2, an impeller 6 of a medium or high pressure radial fan is placed, the engine (not shown) of which is installed inside the cylindrical shell 7, and its shaft is directly connected to the impeller 6.

The shell 7 is fixed inside the gas separator body 2 and guide vanes 8 are mounted on its outer surface, which can be rotated. The blades 8 can be flat or curved and, due to the possibility of rotation, perform the function of a swirl.

In the outlet pipe of the gas separator body 2, an annular pocket (not shown) is connected to the inlet pipe of the cyclone 1.

During operation of the device, gas masses with suspended particles of mechanical impurities, for example, air masses with suspended particles of dust and impurities, are pumped by the impeller 6 of the fan into the gas separator housing 2. The air flow is accelerated in the annular gap between the shell 7 and the inner surface of the gas separator 2 and on a large speed is twisted when interacting with the guide vanes 8. Inside, pressure is created (from 1500 Pa). In an accelerated and swirling flow, suspended particles under the action of inertia and their own linear velocities are separated from the main air flow, falling into an annular pocket, and then into cyclone 1.

In cyclone 1, mechanical impurities are separated and discharged from the cyclone through a lock gate (not shown). The purified air through the duct 3 is sent to the gas separator 2 in front of the impeller 6 of the fan, it is suctioned last and undergoes secondary cleaning.
