Abstract

This invention relates to the field of the coking industry. The purpose of the invention is to reduce dust and gas emissions and coke burnout in a car. For this, the device is provided with discharge headers placed along the side edges of the umbrella. The area of the collector in any place along its height is equal to the area of the exhaust pipe of the exhauster, and the length of the outlet is equal to the width of the body of the coke quenching car. 3 il.

Description

This invention relates to a coke-chemical industry, in particular to the equipment of coke ovens, workshops;

The purpose of the invention is to reduce coke burnout in the car and dust and gas emissions.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a collector diagram.

The device contains a coke line looking for 1, to which is attached the jacket 2 with a pipeline 3, communicating with a tank 4, movably mounted on a coking car 5. The smoke pipe 6 is connected by a pipe 7 with a tap 1a1 of the pipeline channel 3 and a gas pipeline 8 with a collector 9 .

The collector 9, which guides the gas from the smoke exhauster to the COKE WAGON, is made in the form of a rectangular pipe, which extends downwards and adjoins to the leguminous surfaces of the hood.

The cross-sectional area of the collector at any place along its height And is equal to the area F of the cross-section of the exhaust pipe of the exhauster. At the same time, the length of the outlet opening L of the collection is equal to the width of the body of the coke box car. Then the width of the outlet of the collector is determined by the formula

R - - L

where B is a woof hole

collector;

F - exhaust outlet area.

The device works as follows

In the transport position, the door-removable machine moves along paths with the Coke Guide pushed away from the front of the furnace. When unloading coke from the coke oven, the bogie and coke box car 5 are set to unload the coke from the given furnace. By means of nature, the tank 4, installed on the JCOKCOB03HOM car 5, rises before the outlet of the pipeline 3 is immersed in the liquid. With the beginning of the discharge of coke include the exhauster (exhausters, if there are two). Under the influence of the smoke exhauster, gas at high speed enters the tank 4, where it is cleaned of dust. The cleaned gas is discharged through the gas exhaust duct into the gas pipeline 8 of the collector 9 and onto the coke. At the same time, the gas jet creates a screen that prevents (piercing gas emissions outside the umbrella and, pushing atmospheric air from the surface, coke, reduces its waste,

. As a result of the contact from the back of the coke-directed coke, the surface is post-cooled - it cools.

The particles of coke fuck, falling from the collector to hot coke, are burned after stopping the gas supply,

Thus, the total amount of flue emissions into the atmosphere is reduced and coke waste is reduced,

Assuming that the coke waste decreases by 0.01% of the mass of coke that is in the car for one transfer, then with a battery capacity of 900 kt / g, 9000 tons of coke are stored,
