Abstract

The utility model relates to a dust removal smoke guiding car with double U-shaped pipes of tamping coke oven, which comprises a car body, a smoke guiding cover device, a double U-shaped pipe system, an upward pipe cleaning device, a high and low pressure ammonia switching and an upward pipe water close pipe, and an on-off device of a valve body. The double U-shaped pipe system comprises a U-shaped smoke guiding pipe arranged in the car body side and a U-shaped smoke guiding pipe arranged in the middle of the car body. The double U-shaped pipes are communicated with a smoke guiding hole in an upward erection coal coking chamber and a coking chamber smoke guiding hole at two sides of the upward erection coal coking chamber in the last phrase of coking. Compared with the normally used dust removal smoke guiding car of tamping coke oven, the utility model has the advantages of flexible adjustment, accurate control, convenient overhauling, reasonable structure disposal, less investment without additional space occupation, noticeable energy saving effect without smoke leakage and second pollution, etc.

Description

A kind of tamping coke oven dust smoke-guiding car of double u-tube

Technical field

The utility model relates to a kind of special equipment of deriving flue gas when coalingging for tampering coking oven smoothly, particularly a kind of tamping coke oven dust smoke-guiding car of double u-tube.

Background technology

At present, the dust removing and smoke-guiding vehicle that domestic and international large-scale tampering coking oven uses has nothing in common with each other, have the dedusting of employing earth station that coal-charging smoke is drawn into the method that earth station carries out udst separation again with blower fan, its weak point is that equipment is huge, floor space is big, energy consumption is high, dust removing effects is undesirable, the investment is many; Have the dedusting of employing earth station that coal-charging smoke burning back is drawn into the method that earth station carries out udst separation again with blower fan, its weak point is that equipment is huge, floor space is big, energy consumption is high, the investment is many; Have on dedusting car with the blower fan suction and burn onboard, wash, diffuse, its weak point is that burning washing back produces a large amount of waste water, causes secondary pollution, energy consumption height, burning to be difficult to control; Also have the smoke-guiding car of the band list U type pipe that uses in India, its weak point is to still have a large amount of flue gases to emerge from fire door when coalingging, and dust removing effects is undesirable.

The utility model content

The utility model has overcome the problem of above-mentioned existence, and purpose is that design is a kind of for tampering coking oven tamping coke oven dust smoke-guiding car that use, that can derive a kind of double u-tube of the flue gas of coalingging smoothly.

The utility model is achieved through the following technical solutions: a kind of tamping coke oven dust smoke-guiding car of double u-tube, by car body, open and close smoke guiding hole lid arrangement, double u-tube system, tedge clearing apparatus, high-low pressure ammoniacal liquor switches and the headstock gear of tedge manhole cover, valve body etc. is formed, the double u-tube system comprises that the U type that the U type that is positioned at the car body pusher side is led smoke pipe and is positioned at car body middle part leads smoke pipe, and double u-tube is communicated with formal dress coal carbonization chamber smoke guiding hole and both sides, formal dress coal carbonization chamber are in the coking carbonization chamber smoke guiding hole in latter stage.

The tamping coke oven dust smoke-guiding car of a kind of double u-tube of the utility model is compared with tampering coking oven dust removing and smoke-guiding vehicle commonly used, have regulate flexibly, control accurately, maintenance convenience, reasonable structural arrangement, reduced investment do not need extra occupation of land, energy-saving effect significantly, no flue gas leakage and do not produce advantage such as secondary pollution.
