Abstract

The utility model relates to an oven door flue gas gathering device of a controllable automatic suction-type coke oven machine, which is composed of a flue gas conveying pipeline, a controllable automatic valve, a lower dust collecting cover, a pipeline bracket, and a control system of the automatic valve. The pipeline bracket is arranged at the upper part of the furnace stay of a coke oven, the flue gas conveying pipeline is positioned at the upper part of the pipeline bracket, the controllable automatic valve is connected with the lower part of the flue gas conveying pipeline, the controllable automatic valve is positioned in the middle of two adjacent furnace stays, the lower dust collecting cover is connected with the lower part of the controllable automatic valve, and the space of the two adjacent furnace stays at the upper part of the carbonization chamber can be closed by the lower dust collecting cover. The device is suitable for dust removing operation of the machine side when the coal is filled in a variety of stamp charging coke ovens, moreover, any reconstruction is not needed to be performed to the coke oven body, and no influence can be caused to the process operation and the service life of the coke oven. The device has the advantages that the adjustment is flexible, the control is accurate, the overhaul is convenient, the structural arrangement is reasonable, the investment is less, the land is not needed to be additionally occupied, the energy-saving effect is obvious, and the flue gas leakage phenomenon and the secondary pollution can not be caused.

Description

The controlled auto-pumping type coke oven side entrance smoke gas gathering-device

Technical field

The utility model relate to a kind of when the tamping coke oven coal-charging the effective special equipment of control coke oven machine side smoke spillage, particularly a kind of controlled auto-pumping type coke oven side entrance smoke gas gathering-device.

Background technology

At present, the flue gas that tamping coke furnace both domestic and external gives out the coke oven machine side furnace door place in the process of coalingging does not still have effective means to be handled, this has become a key factor of restriction TAMPING COKING PROCESS development, along with countries in the world to the improving constantly of environmental requirement, the difficult problem that solves this restriction TAMPING COKING PROCESS development is urgent day by day.The dedusting method of tampering coking oven use both at home and abroad is mainly based on the dust collection for charging car, its method mainly is that the flue dust that gives out when coalingging is drawn into dedusting earth station at the furnace roof smoke guiding hole by the coal loading, smoke conduction car and carries out udst separation, the smoke-guiding car that also has the band list U type pipe that uses in India, be that flue gas that the hole carbonization chamber the produces smoke-guiding car by band U type pipe of will just coalingging imports adjacent being in the coking carbonization chamber in latter stage, to solve the excessive problem of flue gas.Tamping coke oven coal-charging wing furnace on opportunity door is opened fully, although above-mentioned various dust suppression is arranged, still has a large amount of flue gases to overflow from fire door when coalingging, and dust removing effects is undesirable, causes environmental pollution.

Summary of the invention

The purpose of this utility model provides a kind of controlled auto-pumping type coke oven side entrance smoke gas gathering-device, and this device can effectively solve tamping coke furnace at the collection governing problem of wing furnace door place's effusion on opportunity flue gas of coalingging.

For achieving the above object, the utility model is achieved through the following technical solutions:

The controlled auto-pumping type coke oven side entrance smoke gas gathering-device, it is characterized in that: this device is made up of the control system of flue gas transfer canal, controlled automatic valve, bottom dust gathering arrester, support of pipelines, automatic valve, be provided with support of pipelines on coke oven furnace stay top, the flue gas transfer canal is positioned at support of pipelines top, be connected with controlled automatic valve below the flue gas transfer canal, controlled automatic valve is positioned in the middle of two adjacent furnace stays, connect the bottom dust gathering arrester below the controlled automatic valve, the bottom dust gathering arrester has sealed the space of adjacent two furnace stays on carbonization chamber top.

This device uses in the time of can be for tamping coke oven coal-charging.

Compared with prior art, the beneficial effects of the utility model are:

1, be applicable to the pusher side dust removing of newly-built, renovating and enlarging various tamping coke furnaces, and the furnace body of need not focusing carries out any transformation, the technological operation of coke oven and the life-span of coke oven are also had no effect;

2, regulate flexibly, control accurately, maintenance convenience, reasonable structural arrangement, small investment, do not need that extra occupation of land, energy-saving effect are remarkable, no smoke spillage and do not produce secondary pollution.

Fig. 2 is a controlled auto-pumping type coke oven side entrance smoke gas gathering-device side sectional view;

Among the figure: 1-flue gas transfer canal, the controlled automatic valve of 2-, 3-bottom dust gathering arrester, 4-support of pipelines, 5-furnace stay, 6-control system, 7-carbonization chamber

The specific embodiment

A kind of controlled auto-pumping type coke oven side entrance smoke gas gathering-device of the utility model is achieved in that below in conjunction with accompanying drawing the utility model is elaborated.

See Fig. 1, Fig. 2, a kind of controlled auto-pumping type coke oven side entrance smoke gas gathering-device, this device is by flue gas transfer canal 1, controlled automatic valve 2, bottom dust gathering arrester 3, support of pipelines 4, the control system 6 of automatic valve is formed, be provided with support of pipelines 4 on coke oven furnace stay 5 tops, flue gas transfer canal 1 is positioned at support of pipelines 4 tops, be connected with controlled automatic valve 2 below the flue gas transfer canal 1, controlled automatic valve 2 is positioned in the middle of two adjacent furnace stays 5, connect bottom dust gathering arrester 3 below the controlled automatic valve 2, bottom dust gathering arrester 3 has sealed the space of adjacent two furnace stays 5 on carbonization chamber top.

The course of work of this device is described below:

Cooperate furnace roof dedusting car or smoke-guiding car when coalingging, controlled automatic valve 2 is opened automatically, form certain suction at bottom dust gathering arrester 3 places and accurately control suitable flow, collect the flue gas that the carbonization chamber pusher side is overflowed to greatest extent, and the flue gas of overflowing imported flue gas transfer canal 1 fast, in flue gas transfer canal 1 is delivered to the coke discharging and dedusting pipeline, as safe as a house reliable, do not need to increase again other facilities.

The operation of this device can be adopted machinery control on coke vehicle, also can carry out remote auto control in Central Control Room, to realize the automatic open close of controlled automatic valve, does not have flue gas to escape phenomenon in the operating process.

The utility model controlled auto-pumping type coke oven side entrance smoke gas gathering-device; be applicable to coalingging of all tamping coke furnaces; the flue gas that gathering machine wing furnace door place gives out in the process of coalingging is not enumerated in the specific embodiment one by one, all within rights protection scope of the present utility model.
