Description

(54) DEVICE FOR DOWNLOADING DISPERSTER 1X MATERIALS

The present invention relates to devices for loading bulk granular material into fluidized bed apparatus and can be used in the metallurgical, chemical industry, as well as in industry.

building materials.

A device for loading dispersed materials into fluidized bed aggregates is known, comprising a chamber with a vault, side and end walls, a pipe for material supply, a gas distribution device located in the lower part of the chamber, and a window for removing material. The pipe for material supply is open in the side wall and the window is in the vault.

The disadvantages of the known device are the high unit costs of the transporting agent, which leads to the cooling of the material (when hot MaTepaana) is supplied j and possible disruption of the gas-dynamic mode of the bale layer.

The aim of the invention is to reduce the consumption of the transporting agent and stabilize the gas-dynamic regime of the fluidized bed.

This is achieved by the fact that the device is equipped with a nozzle for outputting large fractions of the material located in the lower part of the chamber; The distance between the lower edge of the pipe for material supply and the lower edge of the window and the distance between the lower edge of the window and the gas distribution device is 1.0 and 2.0-3.0, O of the width of the chamber section respectively. The lower part of the pipe for the supply of material is installed vertically, and the height of this area is not less than the width-d of PatruGzh.

The drawing shows the proposed device, the cut.

A device for freezing dispersed materials contains a chamber 1 with side walls 2, stage 3, pipe 4 for supplying material, a gas distributing device 5 located in the building

parts of the camera 1, n window 6, performed the unit increases the performance of the device,

in the side wall 2. Branch pipe, 4 is located The flow rate of the blow must comply with the feed arch 3 near the other side wall of the material with an external charging device installed at an angle of natural angle to the pipe 4, otherwise

sa material, with the lower part of the nozzle,; or may overflow the chamber

KA 4 is installed vertically, and the height, or its emptying and the breakdown of gases from the heights of the site is not less than the width of the nozzle 4, Gata.

Claims (1)

In the lower part of chamber 1 there is an outlet 7 for outputting large fractions of the material, Distance} |. between the lower cut of the nozzle 4 and the lower strap of the window 6 and the distance 1 between the lower edge of the window 6 and the gas distribution device 5 is (O, 1 - 1.0) a and (2.0 - 3, O) and 5, respectively, where and the width of the flow section jtaMepbi 1,: Preferably b - (0.4 - 0.6) a and llg (2.s5 - 2.7) and , 5 2 times the pressure of the fluidized bed to blow at the loading point J1 g (1 5-2) Р1 / Т e, cl I "where RSL pressure at the loading point4, Tmsas bulk density of the loading material ,, Device p It works as follows. The loading material is fed to the nozzle 4. It is fed into chamber 1 with the blown off and fills it and the nozzle 4. The loaded material flows out of the nozzle 4 and through the window 6 enters the boiling layer of the unit. The minimum consumption of granular material with constant design parameters corresponds to the flow rate that provides the first critical speed in the flow area of chamber 1, t. e, the rate of onset of fluidization. When increasing the flow rate, blow up to a certain pre-formula 1,. Device for loading dispersed materials into fluidized bed aggregates, including a chamber with a vault, side and end walls, a pipe for supplying material, a gas distribution unit located in the lower chamber, and a window to remove the material, so that with the aim of reducing the consumption of the transporting agent and stabilizing the gas-dynamic regime of the fluidized bed, the device is equipped with a pipe for outputting large fractions of the material The bottom of the chamber is located at the bottom of the chamber. and the distance between the lower edge of the window and the gas distribution device is 0.1-1.0 and 2 g 3 the widths of the flow area of the chamber, respectively. 2, the device according to claim 1, wherein the lower part of the pipe for the supply of material is installed vertically, and the height of this section is not less than the width of the pipe.
