Abstract

FIELD: chemistry.SUBSTANCE: invention can be used in coking industry. In the method, the coke dry quenching plant consists of quenching chamber 1, charging device 2, blowing device 3 and discharge device 4 with chutes 5. Oval closed box 6 is connected to chute 5, and two rotary devices 7 with radial guide vanes 8 are arranged in it symmetrically with respect to the axis of chamber 1. In the bottom of box 6 there are two openings for coke gathering. Cooled coke from quenching chamber 1 enters oval closed box 6 where radial guide blades 8, which are operating in reverse mode, alternately rake it towards one or the other aperture and unload the coke through chutes 12 onto the conveyors.EFFECT: proposed invention provides an increase in operating efficiency by increasing the gas density of the device, simplifying its maintenance and repair, and reducing its size.1 cl, 3 dwg

Description

The invention relates to installations for dry quenching of coke and may find application in the coke industry.

A known installation of dry coke quenching, including a quenching chamber, a loading device, a blasting device, an unloading device, in the heat of which a rotating drum is mounted so that the axis of rotation of the drum is perpendicular to the axis of the quenching chamber (see, for example, patent JPS61136588, IPC: C10B 39 / 02, publ. 06.24.1986)

There is also known a dry coke quenching installation, including a quenching chamber, a loading device, a blowing device, an unloading device with a successively mounted upper hopper, an intermediate hopper with shutters, a reloading hopper and a lower hopper, in which a rotating drum with an adjustable rotation speed is installed, interacting with two unloading estruses, installed in such a way that the axis of rotation of the drum is perpendicular to the axis of the quenching chamber (see, for example, patent RU 31381, IPC: C10B 39/02, publ. 10.08.2 003).

In technical essence and the achieved effect, the known device is the closest to the claimed.

Common disadvantages of the known devices are the insufficient reliability of the rotary drum, the difficulty in maintenance, the low gas density of the unloading device and the large dimensions, which generally affects the efficiency of the installation.

The basis of the invention is the task of creating a dry quenching extinguishing installation of coke, which allows to increase the efficiency of its operation by increasing the gas density of the device, simplifying maintenance and repair, and reducing the size.

The problem is solved in the installation of dry quenching of coke, including a quenching chamber, a loading device, a blowing device, an unloading device with estrus connected with an intermediate rotating device with an adjustable rotation speed; according to the invention, the intermediate device is an oval closed box connected to a groove, in which two rotor devices with radial guide vanes are placed symmetrically with respect to the camera axis, and two openings for coke exit are made in the bottom of the box, each divided by partitions into two sectors connected with gutters feeding coke to the conveyor.

A distinctive feature of the claimed device is that

- the intermediate device is an oval closed box connected to the estrus, in which two rotor devices with radial guide vanes are placed symmetrically with respect to the camera axis,

- in the bottom of the box there are two openings for coke escaping, each divided by partitions into two sectors connected with the troughs supplying coke to the conveyor.

Based on the described prior art it follows that this difference is new.

In the figure of FIG. 1 is a perspective view; FIG. 2 is a section A-A, in FIG. 3 section BB.

The dry coke quenching installation consists of a quenching chamber 1, a loading device 2, a blowing device 3, an unloading device 4 with estrus 5, an oval closed duct 6 connected to the estrus 5, in which two rotor devices 7 with radial guides are placed symmetrically with respect to the axis of the chamber 1 blades 8. In the bottom of the box 6 there are two openings 9 for coke exiting, each divided by partitions 10 into two sectors 11, which are connected with the grooves 12 that supply coke to the conveyor.

The dry coke quenching unit works this way.

In the extinguishing chamber 1 through the loading device 2 enters the hot coke. Towards him through the blowing device 3 serves cooling gas. Cooled coke from the quenching chamber 1 through an unloading funnel of 5 estrus enters an oval closed box with radial guide vanes 8 operating in reverse mode, alternately raking to one or the other opening 9, unloading through troughs 12 onto conveyors.

Technical and economic advantages of the claimed device compared to the prototype device are to increase the efficiency of its operation by increasing the gas density of the device, simplifying maintenance and repair, and reducing the size.
