RU55647U1 - Vortex Dust Collector - Google Patents

Abstract

The utility model relates to techniques for cleaning gas from dust. The vortex dust collector contains a cylindrical body with a conical dust collector, an upper axial outlet pipe, a rectangular inlet upper tangential pipe, a dusty gas inlet tangential pipe with a baffle plate and a conical swirl located in the lower part of the body. The difference is that the lower tangential nozzle is equipped with a damper for regulating the flow of dusty air and an additional damper for introducing and regulating the flow of clean air.

Description

The utility model relates to devices for separating dispersed particles from gases and can find application in various industries - chemical, food, woodworking, construction and other industries.

Known vortex dust collector containing a cylindrical body with a conical dust collector, located in its lower part, a tangential pipe for entering dusty gas with a baffle plate and a conical swirl. In the upper part of the housing there is a tangential rectangular section for introducing dusty gas and an axial nozzle for removing purified gas (see utility model description to the RF patent No. 39513, MKI V 04 S 3/06, V 01 D 45/12, publication 08/10/2004 d).

The disadvantages of this design include the lack of the ability to control the concentration of dust in the dust flow coming to the cleaning through the lower inlet of the vortex dust collector.

The essence of the proposed utility model lies in the fact that in the vortex dust collector containing a cylindrical housing with a conical dust collector, there is a tangential pipe of rectangular cross-section of the input of dusty gas and an axial pipe of the output of purified gas located in the lower part of the body of the tangential pipe of the input of dusty gas from with a bump washer and a conical swirl, the lower tangential branch pipe is equipped with a flap for regulating the flow of dusty gas and the additional valve to enter the clean air

The invention is illustrated in the drawing, where:

the figure 1 shows a vortex dust collector, General view.

The vortex dust collector comprises a cylindrical body 1 with a conical dust collector 2, a tangential nozzle 3 of rectangular cross section for introducing the gas to be purified, and an axial nozzle 4 for removing the purified gas located in its upper part.

At the bottom of the dust collector there is a tangential pipe 5 for introducing dusty gas with a conical swirl 6 and a baffle plate 7. The lower inlet tangential pipe 5 contains a shutter 8 for regulating the flow of dusty air and a shutter 9 for supplying clean air to the dust collector.

Vortex dust collector operates as follows. The cleaned gas enters the housing 1 in two streams. In the upper part of the vortex dust collector through the tangential pipe 3, and in the lower part of the body through the tangential pipe 5 and swirl 6 with an annular baffle plate 7.

The generated gas stream moves to the outlet pipe 4 of the dust collector, and dust particles are discarded to the walls of the dust collector by centrifugal forces.

The swirling gas stream moves in the axial direction, and a secondary gas stream flows through the tangential nozzle towards it, both in the same direction. The interaction of gas flows enhances the centrifugal forces acting on dust particles, which are effectively discarded and sent along the wall of the cylindrical body 1 to the bottom of the apparatus under the baffle plate 7. The released dust enters the conical dust collector 2, and the cleaned gas is discharged through the nozzle 4 into the atmosphere.

To increase the efficiency of dust collection using the shutter 8, the supply of dusty gas and dust flow coming from the aspiration system (not shown) is controlled. Partial or full opening of the control flap 8 changes the flow rate of dusty air. An additional damper 9 is the input of clean air, which

allows you to change over a wide range of dust entering for cleaning through the lower pipe 5 of the dust stream.

The flow of gas and dust flow is controlled by shutters 8 and 9 so that the ratio of the air flow rate supplied to the upper and lower inlet of the vortex dust collector remains constant.

Depending on the technological requirements of the production process, clean air supplied to the lower tangential branch pipe 5 may be heated, cooled or humidified.

The proposed design of the utility model improves the efficiency of cleaning dusty gases.
