Abstract

The utility model relates to a water sealing smoke guiding main pipe device of a dedusting system for a coking furnace ground station. The water sealing smoke guiding main pipe device comprises a smoke guiding main pipe line, wherein one end of the smoke guiding main pipe line is communicated with the upper end of a U-shaped water sealing pipeline, while the other end of the smoke guiding main pipe line is connected with one end of a water sealing plate, the other end of the water sealing plate extends into the middle of the U-shaped water sealing pipeline, and water is stored in the U-shaped water sealing pipeline; a U-shaped smoke guiding pipe is mounted in the U-shaped water sealing pipeline and communicated with a coke guide gas collecting hood through a gas hood smoke guiding pipe; the bottom part of the U-shaped water sealing pipeline is communicated with a waste slag discharge device; an overflow device is mounted at the upper part of the U-shaped water sealing pipeline; and the coke guide gas collecting hood integrated with the coke guide is arranged. The water sealing smoke guiding main pipe device is used for sealing the smoke guiding pipe when the coke guide gas collecting hood is moved; as the U-shaped smoke guiding pipe is surrounded and sealed by the water in the U-shaped water sealing pipeline, when coke is discharged and coal is added in the coking furnace, no matter whether the coke guide halts or moves, the smoke leaded into the main pipe through the U-shaped smoke guiding pipe is prevented from being leaked, the smoke produced when the coke is discharged and the coal is added can be completely guided into the smoke guiding main pipeline without any butting equipment, and the smoke is prevented from being leaked.

Description

Coking furnace earth station dust removing system water-lute is led cigarette main device

Technical field

The utility model relates to a kind of flue gas conveying technology that is used for the coke oven dust earth station system.

Background technology

" turnover panel gate-type pipeline docking facilities " is that coke oven dust terrestrial station is used for a kind of common equipment that flue gas is carried, and plate-turning door pipeline docking facilities exists inleakage big, and maintenance capacity in service is big, needs shortcomings such as the power of induced draft fan is big.

The utility model content

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of inleakage little, few maintenance, and energy-conservation water-lute is led cigarette main device.

The utility model is achieved in that

Have one to lead cigarette main main pipe line 3, the one end is communicated with the upper end of U type seal pipe 8, and the other end is connecting an end of water seal board 4, and the other end of water seal board 4 stretches in the U type syphon trap 8, has water in the U type seal pipe 8, and certain water level is arranged; In the U type horizontal pipe 8 the U type is housed and leads smoke pipe 2, the U type is led smoke pipe 2 and lead cigarette in U type seal pipe 8, and this U type is led smoke pipe 2 and led

smoke pipe

5 and 6 connections of coke guide gas skirt by petticoat pipe; The bottom of U type seal pipe 8 is communicated with waste residue blowdown apparatus 1; Overflow device 7 is equipped with on U type seal pipe 8 tops.The coke guide gas skirt 6 that the one that links to each other with coke guide is arranged, coke guide gas skirt 6 is led smoke pipe 2 with the U type and is moved in the coal and the process of the discharging of the coke.

The described cigarette main main pipe line 3, U type seal pipe 8 of leading is garden shape steelwork pipe; Wholely lead cigarette main main pipe line 3 and U type seal pipe 8 length are longer than the coke oven entire length.

Principle of work of the present utility model and process are:

A. coke oven is at coal with when the discharging of the coke, the flue gas that coal discharges of the coke and produces in the process, and deliver in the dedusting earth station system by pipeline and to filter, to gather dust: clean gas enters atmosphere.Flue gas when coal discharges of the coke enters control of dust main 3 by coke guide gas skirt 7, and coke guide gas skirt 7 is to collect flue dust gas under situation about moving.This device is that water seals and leads cigarette main main pipe line 3 and petticoat pipe is led smoke pipe 5, makes coke guide gas skirt 3 be in sealed state moving to pounce in the collection flue dust, and can smoothly ash-laden gas be imported in the dedusting earth station system.

B. the circular smoke guide device of water-lute formula seals in the coke guide gas skirt moves and leads smoke pipe, because the U type is led the encirclement sealed state that smoke pipe 2 is in water in the U type syphon trap 3, in coke oven coal, the process of the discharging of the coke, no matter coke guide gas skirt 6 stops and moves, can both make the U type lead the smoke pipe 2 smooth flue gases that import main pipe does not leak outside, also need not rely on any the service of connection devices, just coal, the flue gas that discharges of the coke can be carried fully in leading cigarette main main pipe line 3, avoid the flue gas leakage phenomenon.

This device tradition " turnover panel gate-type pipeline docking facilities " is compared, and power consumption reduces, and calculates to produce 600,000 tons of coke ovens daily, and working cost is saved more than 1,500,000 yuan.

Characteristics of the present utility model:

1. this device overcomes air leakage phenomena fully; Easy to operate, can under any circumstance whenever connect with main air duct at any time;

2. this device one-step installation debugging, Maintenance free, long-time running is steady, unmanned;

3. this device has the automatic regulatory function of water level, remains on sealing effectiveness in any case;

4. this device has dirty slag exhausting equipment, and keeping does not have latch up phenomenon in the U type water sealed tank forever, can clear up the dirty slag in the U type pipe water sealed tank at any time, guarantees the walking of U type pipe smoothly;

5. this device has certain cooling effect.In coal discharges of the coke process, in the coke oven flue-gas temperature very high-----Yue 300-400 ℃, high like this temperature can be reduced to temperature 200---300 ℃ after leading the smoke pipe cooling by the U type that contains water-lute and surround, and helps gathering dust of dedusting earth station system.

This device has 6. water-lutes effective, because circle is led the cigarette main and placed on the watertight airduct road, enters the major trunk roads flue so overcome water.
