Abstract
The utility model belongs to a smoke purification system used during coke discharge of a coke oven and relates to a dedusting system used for the coke discharge of the coke oven. The dedusting system comprises a coke discharge air suction hood, coke discharge dedusting main pipes, a cyclone dust collector, an impulse dust collector, a ventilator and a silencer device which are connected in sequence. A fixed connector valve is arranged between the coke discharge air suction hood and the coke discharge dedusting main pipe, a balance valve is arranged at the tail end of the coke discharge dedusting main pipe, an expansion joint is arranged inside the coke discharge dedusting main pipe, an electric butterfly valve is arranged between the coke discharge dedusting main pipes, and the coke discharge dedusting main pipes are composed of fixed flat valves. The smoke purification system has the advantages of being good in dedusting effect, high in dedusting efficiency, convenient to install and maintain, low in input cost and the like.
Description
Technical field
The utility model relates to a kind of dust separation system, especially relates to a kind of coke oven coke discharging and dedusting system.
Background technology
Coke oven is in the process of the discharging of the coke, and fervid red Jiao is released from coking chamber by pushing machine in order, and coke falls in the quenching car compartment through leading burnt grid.Fervid coke breaks, and in air, burns after releasing from coking chamber, and the flue gas of generation and burnt dirt are dispersed in the air.It is big to contain burnt dust quantity in this part flue gas, serious environment pollution.Present domestic coke oven coke discharging and dedusting system can not capture a large amount of high-temperature flue gas that coke oven is produced well when the discharging of the coke.
Summary of the invention
The purpose of the utility model provides the coke oven coke discharging and dedusting system of a kind of terrestrial station form, and this dust-removal system can capture a large amount of high-temperature flue gas that coke oven is produced well when the discharging of the coke.
The technical scheme of the utility model: a kind of coke oven coke discharging and dedusting system; Comprise the air-suction cover that discharges of the coke, coke discharging and dedusting main, tornado dust collector, pulse bag type dust collector, ventilator, the muffler assembly that are tightly connected successively; Be provided with the fixed interface valve between air-suction cover and the coke discharging and dedusting main the discharging of the coke; Be provided with equilibrium valve at coke discharging and dedusting main end, be provided with expansion joint, be provided with electric butterfly valve between coke discharging and dedusting main and the coke discharging and dedusting main in coke discharging and dedusting main inside.
As preferably, above-mentioned coke discharging and dedusting main is made up of fixing flap valve.
The principle of work of the utility model: but the large-scale range hood big area on the coke guiding locomotive covers quenching car top; Make and fall the high hot flue gas of emerging at the red-hot coke of quenching car; In terrestrial station, get in the range hood under the attraction of induced-draft fan; Get into the coke discharging and dedusting main through interface valve, descending and isolate thick coke powder particle through the tornado dust collector flue-gas temperature again falls into the bottom ash bucket.Flue gas after the cooling gets into pulse bag type dust collector and purifies, and purified gas gets into induced-draft fan and sourdine through the gas collection airduct on fly-ash separator top, enters atmosphere through aiutage again.The dust that fly-ash separator is collected exports double-deck dust discharge valve through ash bucket and is discharged into scraper conveyor, transports to ash-storing bin.
The beneficial effect of the utility model: the first, low, the simple in structure science of the utility model air leak rate of air curtain, fabrication and installation are easy to maintenance, and input cost is low; The second, what the induced-draft fan in the utility model adopted is the speed control by frequency variation scheme, thereby can reduce daily power consumption expense, to reach energy-saving effect.The 3rd, the utility model good dedusting effect, efficiency of dust collection is high.
Description of drawings
Fig. 1 is the structural representation of a kind of coke oven coke discharging and dedusting system that proposes of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
As shown in Figure 1; The utility model comprises the air-suction cover 1 that discharges of the coke, coke discharging and dedusting main 2, tornado dust collector 3, pulse bag type dust collector 4, ventilator 5, muffler assembly 6, and the air-suction cover 1 that discharges of the coke, coke discharging and dedusting main 2, tornado dust collector 3, pulse bag type dust collector 4, ventilator 5, sourdine 6 are tightly connected successively.Be provided with the fixed interface valve between air-suction cover 1 and the coke discharging and dedusting main 2 the discharging of the coke; Be provided with equilibrium valve at coke discharging and dedusting main 2 ends; Be provided with expansion joint in coke discharging and dedusting main 2 inside; Be provided with electric butterfly valve between coke discharging and dedusting main 2 and the coke discharging and dedusting main 2, wherein coke discharging and dedusting main 2 is made up of fixing flap valve.
When equilibrium valve is opened, can produce noise during air admission control of dust main 2, this moment, sound damper 6 utilized its inner sound-absorbing material to reduce noise.
Claims (2)
1. coke oven coke discharging and dedusting system; Comprise the air-suction cover that discharges of the coke, coke discharging and dedusting main, tornado dust collector, pulse bag type dust collector, ventilator, the muffler assembly that connect successively; It is characterized in that: above-mentioned the discharging of the coke is provided with the fixed interface valve between air-suction cover and the above-mentioned coke discharging and dedusting main; Above-mentioned coke discharging and dedusting main end is provided with equilibrium valve, and above-mentioned coke discharging and dedusting main inside is provided with expansion joint, is provided with electric butterfly valve between above-mentioned coke discharging and dedusting main and the above-mentioned coke discharging and dedusting main.
