SU1511534A1 - Ash flushing apparatus - Google Patents

Abstract

The invention relates to devices for removing ash (dust) from bunkers of dust collection plants, can be used in the power industry, metallurgy, chemical and other industries of the industry and allows to increase the economy and reliability of operation. In the apparatus, cylinder 4 is mounted vertically on the bottom, and turntable 5 with drive 7 and cleaning 6 blades. The latter clean the internal surface of the hull from deposits. The cylinder contributes to the swirling flow of water, which increases the wettability of the ash. The resulting deposits are cleaned with 6 blades, 1 hp blades. f-ly, 3 ill.

Description

(L

with:

The invention relates to a device for the wet removal of ash collected in electrostatic precipitators or other dry dust catchers in the flue gas cleaning process, and can be used in the energy, metallurgical, chemical and other industries.

The purpose of the invention is to increase efficiency and reliability in operation.

Figure 1 shows the wash tank, a General view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The washing machine contains an ash drain 1 connected to the hole of the cover of housing 2, inside of which there is a mixing chamber 3, where dry ash is mixed with water, a vertical cylinder 4, installed along the axis of the housing, a spinner 5 with cleaning blades 6, wiping off deposits from the walls, and drive blades 7. A swivel 5 is mounted on bearings 8. Water is supplied to the body through the tangential flushing nozzle 9, and the ash from the pulp is discharged into the channel or collector through a drain pipe .10.

The device works as follows.

The ash through the chute 1 enters the casing 2, coming into contact with a water mirror, is wetted in the mixing chamber 3 and, turning into a breeder pulp, is directed to the drain pipe 10 and further into the channel. The water in the ash washer is supplied through a nozzle 9 (multiplicity of 3.0-3.5 tons of water / ash) installed tangentially to the housing 2.

To increase the circulation of water in the housing 2, a pipe-cylinder 4 is installed.
