Description

Description of the invention

The invention belongs to coke ovens without capturing chemical products of coking, to the so-called 2 "hive" ovens, and can be used in the coke industry.

A known coke oven without trapping chemical products of coking, which contains a coking chamber made of refractory material, with a floor space and heating floor channels, a conveyor mounted on a loading and pushing machine on the machine side of the oven, a device for unloading coke from a quenching car on the coke side ovens See, for example, Production of coke with heat capture at plant 70 of the Indiana Harbor coke company - working hours. A.R. Ellis and K.J. Schuette, w. "SoKe takKipo. Mo2. 1999).

Also known is a coke oven without trapping chemical products of coking, which contains a coking chamber made of refractory material, with a vaulted space that is heated and heating channels, a loading machine consisting of a movable frame and devices for loading coal charges to the furnace and delivery from the furnace of coke on the machine side, devices for receiving 15 coke and its quenching, and further delivery to the coke ramp on the coke side, as well as a general outlet gas collector of combustion products, located on the upper platform of the coke oven. See, for example, Pat. U/O 02/29345; IPC; R27DZ/O6; op 26.07.011.

In terms of technical essentiality and the result achieved, the known device is the closest to what is claimed. 20 The general disadvantages of the known devices are the complexity and duration of loading the coke oven with the coal charge, the very large areas occupied for production, as it requires the use of planer devices and a water-cooled loading conveyor that feeds into the heated horizontal coking chamber along its entire length, and the unloading of coke cake using a coke ejector into a horizontal extinguishing car of the same length. p. 29 The invention is based on the task of creating a coke oven without trapping chemical products of coking, (9 which allows to simplify the technology, significantly reduce the usable area for production, reduce labor costs, and harmful impact on the environment.

The task is solved in a coke oven without trapping chemical products of coking, which contains a coking chamber with a heated vaulted space and heating floor channels, sch 30 loading wagon, loading device, unloading device, extinguishing wagon; according to the invention, the furnace is made in the form of two coupled equi-inclined coking chambers, which have a common top, along which a loading device is located, made in the form of a central loading hatch, connected to a loading hopper and a loading wagon equipped with "I the telescopic part of the hopper, inside which is placed the conical distributor of the charge on both sides of the chamber 35. -

A distinctive feature of the claimed device is: - the furnace is made in the form of two conjugate coking chambers, which have a common top, along the entire length of which there is a loading device, made in the form of a central "loading hatch, connected to a loading hopper and a loading wagon , equipped with Z 0 telescopic part of the hopper, inside which a conical charge distributor is placed on both sides of the chamber.

From" Based on the described state of the art, it follows that the specified distinguishing feature is new.

Features of the operation of traditional furnaces of the "hive" type are the presence of a uniform layer of coal charge over the entire height, which is laid out with the help of special devices. The authors established that if the coking chamber is placed at an angle that corresponds to the angle of the natural slope of the coal charge, then the charge is laid out in a uniform layer in height without the use of special transport and glider "" devices inside. In this regard, it becomes possible to combine two slopes on different sides of the coking chamber together and load coal simultaneously into both chambers with the help of a wagon installed on the common hatch. At the same time, the coke oven will not have a machine side, but will have two coke sides. There is no need from 20 to use gliders and a loading conveyor.

The loading time is significantly reduced, the productivity of the furnace will increase twice. Large usable areas are vacated.

In Fig. shows the scheme of the claimed device.

The coke oven without capturing the chemical products of coking contains two coupled equi-inclined coking chambers 1, which have a common top 2, along the entire length of which there is a central loading

GF) hatch 3, loading hopper 4, loading car 7. Above the coking chambers 1 there is a vaulted space 5 of triangular cross-section, and under the coking chambers are heating feed channels 6. o The loading car 7 is equipped with a telescopic part 8 of the hopper 4, inside which a conical distributor 9 is placed Channels 10 for removing combustion products are additionally placed in the vaulted space 5. 60 On the sides of the coke, as unloading devices 11, there are doors for self-adjusting the coke into the extinguishing car 12.

The claimed device works as follows.

The coal charge for coking is fed by the loading wagon 7. The telescopic part 8 is introduced into the loading hopper 4 of the central loading hatch Z from the wagon 7. The conical distributor 9 62 is lowered to the lower position during loading and the charge enters the two coking chambers 1 at the same time.

At the end of loading, the conical distributor 9 returns to the upper position. Thanks to the inclination of the coking chambers 1, the charge is located according to the angle of the natural slope evenly along the entire height.

The coking process is carried out by heating the charge from below with heat from the heating bottom channels 6 and

From above, heat from the combustion of volatile chemical products above the coal loading. Volatile chemical products created during coking are burned, and the products of their combustion are removed through floor channels 10 in the vaulted space 5, and then through channel 10. Coke is unloaded from the furnace by lifting the door of the unloading device 11 by self-lowering at the same time into two extinguishing cars 12 on two sides of coke. 70 Technical and economic advantages of the claimed device, in comparison with the prototype device, consist in reducing the useful area occupied for production, reducing labor costs, increasing productivity by two times, simplifying technology, reducing the harmful impact on the environment.
