Abstract

A device for cleaning industrial gases, containing a vertical body with branch pipes for supplying and removing the gas to be cleaned, a gas distribution grid with inclined profile blades, an irrigation device in the form of a truncated cone installed on the lower base on the gas distribution grid, fittings for supplying and removing absorbent, characterized in that the device equipped with a branch pipe, the upper edge of which is connected to the branch pipe, and the lower edge is at the height of the upper base of the sprinkler.

Description

The invention relates to devices of the absorption type with a nozzle in the form of a centrifugal fluidized bed of dispersed material and can be used in chemical, metallurgical and other industries.

A device for cleaning gases in the form of an absorber with a centrifugal fluidized bed of the nozzle [1], containing a vertical housing with nozzles for supplying and discharging the gas to be cleaned, a gas distribution grid with inclined profile vanes for fluidization and circulation of the dispersed material located on it, an irrigation device in the form of a truncated cone installed lower base on the gas distribution grill, fittings for supply and removal of absorbent.

The disadvantage of this device is the decrease in the efficiency of gas purification due to the entrainment of droplets of absorbent by the flow of the purified gas.

The utility model is aimed at increasing the efficiency of gas purification by eliminating the entrainment of absorbent droplets.

This is achieved by the fact that the device is equipped with a vertical outlet pipe, the upper edge of which is connected to the pipe for removal of purified gas, and the lower edge is at the height of the upper base of the sprinkler.

Figure 1 presents a General view of the device. The industrial gas purification device comprises a vertical housing 1 with nozzles for supplying 2 and removing 3 of the cleaned gas, a gas distribution grid 4 with inclined profile vanes for fluidization and circulation of the dispersed material located on it (not shown in FIG.), An irrigation device 5 in the form of a truncated cone installed by the lower base on the gas distribution grill 4, fittings for supplying 6 and removal of absorbent 7, a vertical outlet pipe 8.

The device operates as follows.

The cleaned gas enters the device through the nozzle 2. Under the action of oriented jets of gas formed in the inclined profile blades of the gas distribution grid 4, the dispersed material of the nozzle is fluidized and moves along the annular channel formed by the body of the apparatus 1 and the sprinkler 5. The absorbent is fed through the nozzle 6 and through the openings in the lateral surface of the sprinkler 5 enters the nozzle layer. Due to the action of centrifugal forces arising from the rotation of the nozzle along the annular channel, the absorbent is filtered towards the apparatus body and ensures uniform wetting of the nozzle particles. As a result of the contact of the gas with the absorbent on the surface of the particles, gas is purified. The spent absorbent through the perforation in the housing 1 and then through the nozzle 7, and the swirling stream of purified gas through the exhaust pipe 8 and then the pipe 3 are removed from the apparatus. Due to the inertial (centrifugal) forces arising from the movement of the swirling flow of the gas to be cleaned in the annular channel formed by the body of the apparatus 1 and the outlet pipe 8, the absorbent droplets carried away from the nozzle are separated.

The use of the proposed device can improve the efficiency of gas purification by eliminating the entrainment of droplets of absorbent purified gas.
