Problems solved by technology

However, the improvement is mainly to increase the geometric size of the carbonization chamber, improve labor productivity, reduce floor space and infrastructure investment, reduce heat loss and improve thermal efficiency.
The reduction of environmental pollution is only due to the reduction of the number of operations, so the problem of environmental pollution by coke ovens has not been effectively or revolutionaryly changed.

Embodiment 1

[0029] Embodiment 1: the structure of coke oven device

[0030] Such as figure 1 , figure 2 A front sectional view of an environmentally friendly coke oven and a pipeline diagram of the coke oven are shown.

[0031] The device of the present invention includes an air separator 1, a pressure reducer 2, an oxygen main pipe 3, an oxygen branch pipe 4, an exchange control valve 5, a small flue 6, a preheater 8, a gas main pipe 9, a horizontal pipe 10, a lower nozzle pipe 11, Exhaust gas branch pipe 12, exhaust gas main pipe 13, and compressor 14, exhaust gas gas-liquid separator 15, heat storage chamber 17, ramp 18, fire passage 19, carbonization chamber 21.

[0032] The coke oven includes a carbonization chamber, a combustion chamber, a chute area, a regenerator, a furnace top area, and a heating system pipeline. It is characterized in that: the heating system pipeline includes an oxygen pipeline, an exhaust gas pipeline, and a gas pipeline. The oxygen pipeline includes an ox...

Embodiment 2

[0035] Example 2: Application of Environmental Protection Coke Oven

[0036] The specific steps are: according to the required amount of air separator 1 to generate 0.25 MPa of low-pressure oxygen, the oxygen pressure is reduced to 0.1 MPa through the pressure reducer 2 and then enters the oxygen main pipe 3, several oxygen branch pipes 4 connected to the oxygen main pipe 3, oxygen branch pipes 4 communicates with the corresponding small flue 6, and controls the opening and closing through the exchange control valve 5, and opens the exchange control valve 5 according to the combustion system of the coke oven combustion chamber (the exchange control valve 5 on the adjacent oxygen branch pipe 4 is closed, and the corresponding exhaust gas branch pipe The exchange control valve 5 on the 12 is opened), so that oxygen enters the small flue 6 and then enters the combustion chamber vertical fire passage 19 through the ramp 18 after heat exchange in the regenerator 17.

Abstract

The invention relates to a coking furnace which comprises carbonization chambers, a combustion chamber, a chute area, regenerative chambers, a furnace top area and heating system pipelines. The coking furnace is characterized in that the heating system pipelines comprise oxygen pipelines, waste gas pipelines and return gas pipelines. The invention further discloses an application method of the environment-friendly coking furnace. The environment-friendly coking furnace is provided with heat through burning of oxygen and gas, and produced waste gas is separated by a gas-liquid separator for use, so that zero release of waste gas is realized, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to an environment-friendly coke oven and its application, in particular to a heating system for an environment-friendly coke oven; it belongs to the technical field of coking. Background technique [0002] So far, the development of the coke oven structure has roughly gone through four stages: pile dry distillation (that is, local method coking), downdraft coke oven, waste heat coke oven and regenerative coke oven. The characteristic of pile dry distillation is that coking and combustion are not separated together, and the heat is provided by the gas produced by coal dry distillation and part of the coal combustion, resulting in low coking rate and serious environmental pollution. The down-flame coke oven transfers the gas produced in the carbonization chamber into the combustion chamber, and introduces air from the upper part of the combustion chamber. The amount of gas cannot be controlled, and at the end of coking, insufficien...
