SU1430073A1 - Condencating dust collector - Google Patents

Abstract

The invention relates to gas cleaning technology and improves the efficiency of collecting fine dust particles. Dust-gas mixture with a temperature of 120-200 ° C along the inlet tangential nozzle enters the spiral channel located in the cylindrical part of the body, where it is twisted, wetted by sprayed water and due to the centrifugal force is thrown into the wall of the cooling jacket 9 into which cold water flows and the waste water is discharged through the nozzle. The tubes 10 communicated with the cavity of the cooling jacket 9 are perforated, and the coolant (water) from the cooling jacket 9 enters the channel where it is dispersed by dust-gas flow into small droplets wetted by the particles of the pier. In the channel, vapor-gas-vapor vapor condensates, the condensate formed and the dispersed water droplets together with the dust particles flow along the walls and

to the outer wall of the channel. Repeated circulation of water, its heating and additional saturation of the dust-gas-vapor flow with water vapor occurs. The purified gas stream is emitted to the atmosphere through the exhaust pipe. 3 il.

i The invention relates to gas cleaning equipment and can be used 1 purification of heated gases containing fine-grained drills in the mountain ,,; h |: chemical and metallurgical industries, particularly for sanitary cleaning of gases after drying the coal ion concentrate before discharge into the atmosphere - yferu.

The purpose of the invention is to increase the efficiency of the collection of fine-dispersed particles of dust due to the additional dispersion of water.

The condensation dust collector contains a cylindrical body 1 with a tangential pipe 2 for supplying a gas-vapor mixture, pipe 3 jjflH supplying a cooling agent (water), pipe for discharging heated water. In addition, the separator is equipped with an exhaust pipe 5 for discharging the purified gas stream into the atmosphere and a sludge collector b. I In the case of a cushion body, there is a curved partition 7 forming a channel 8 in the form of an Archimedes spiral with a jacket cooling 9 with an outer side; the channels of channel 8. In channel 8 there are perforated tubes 10 communicated With cooling jacket 9 and trenches 11 having a slope to the inner wall of the channel B.

The condensation trap is as follows.

Dust-gas mixture with a temperature of 120-200 C through the supply tangential nozzle 2 enters the spiral channel 8, located in the cylindrical part of the housing 1, where

it is twisted, wetted by sprayed water, and due to centrifugal force it is thrown against the wall of the cooling jacket 9, into which cold water constantly flows through the pipe 3 and the waste water is fed through the pipe 4. Through the perforated tubes 10, connected to the cavity of the cooling jacket 9, cold water flows into the channel 8, which is dispersed by a dust-gas flow into small droplets wetting the dust particles. In channel 8, vapor-gas-vapor vapor condensates, condensate formed and dispersed water droplets along with dust particles flow down channel 8 walls partly into the collector pshama 6, and partly into chutes 11 located under the tubes 10. Channels have a slope towards the inner wall of channel 8 Therefore, water flows to this wall and is dispersed by vapor-gas flow. Droplets of dispersed water due to centrifugal force are directed to the outer wall of channel 7. Water is repeatedly circulated, it is heated, and the vapor – gas – vapor flow is additionally saturated with water vapor. The purified gas stream with a temperature of 50-60 ° C is discharged into the atmosphere through the exhaust pipe 5.

Intensive cooling of the vapor-gas flow is carried out in the zone of concentration of aerosol particles by placing holes in the tube from the periphery to the center. At the outer walls of the apparatus, the water from the holes gushes colder and better cools the zone with a high concentration of aerosol particles. As the fluid moves through the tube. 10 it heats up, thereby contributing

more intense steam generation. The inclination of the grooves towards the inner wall of the apparatus also contributes to a better heating of the liquid and more intensive vaporization due to the flow and impact of the liquid on the internal about the curved partition 7, as well as the Subsequent removal, dispersion of it by the gas stream and partially turning into steam.
