Abstract
The invention belongs to a smoke dust purification system in the process of coke discharging of a coke oven and provides a coke discharge dedusting system of the coke oven. The coke discharge dedusting system comprises a coke discharge suction hood, coke discharge dedusting dry tubes, a cyclone dust collector, a pulse-jet bag dust collector, a ventilation fan and a silencer device which are connected in sequence. A fixed connector valve is arranged between the coke discharge suction hood and the coke discharge dedusting dry tubes. A balance valve is arranged at the tail end of the coke discharge dedusting dry tubes. Expansion joints are arranged inside the coke discharge dedusting dry tubes. An electric butterfly valve is arranged between the coke discharge dedusting dry tubes. Each coke discharge dedusting dry tube is formed by a fixed flap valve. The coke discharge dedusting system of the coke oven has the advantages of being good in dust removal effects, high in dust removal efficiency, convenient to install and maintain, low in invested cost and the like.
Description
Technical field
The present invention relates to a kind of dust separation system, especially relate 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 in order by pushing machine, and coke falls in carriage of coke quenching car by leading burnt grid.Fervid coke break, and at combustion synthesis in air, the flue gas of generation and burnt dirt is dispersed in air after releasing from coking chamber.Contain burnt dust quantity in this part flue gas large, 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 produces well when the discharging of the coke.
Summary of the invention
The purpose of this invention is to provide the coke oven coke discharging and dedusting system of a kind of terrestrial station form, this dust-removal system can capture a large amount of high-temperature flue gas that coke oven produces well when the discharging of the coke.
Technical scheme of the present invention: 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 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 in coke discharging and dedusting main inside, control of dust main and discharge of the coke and be provided with electric butterfly valve between the control of dust main discharges of the coke.
As preferably, the above-mentioned control of dust main that discharges of the coke is made of fixing flap valve.
Principle of work of the present invention: but the large-scale range hood big area on 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, enter in range hood under the attraction of induced-draft fan in terrestrial station, enter the coke discharging and dedusting main by interface valve, then descend and isolate thick coke powder particle through the tornado dust collector flue-gas temperatures and fall into the bottom ash bucket.Flue gas after cooling enters pulse bag type dust collector and purifies, and purified gas enters induced-draft fan and sourdine through the gas collection airduct on fly-ash separator top, then enters atmosphere by aiutage.The dust that fly-ash separator is collected is discharged into scraper conveyor through the double-deck dust discharge valve of ash bucket outlet, transports to ash-storing bin.
Beneficial effect of the present invention: the first, air leak rate of air curtain of the present invention is low, science simple in structure, and fabrication and installation are easy to maintenance, and input cost is low; The second, what the induced-draft fan in the present invention adopted is the speed control by frequency variation scheme, thereby can reduce daily power consumption expense, to reach energy-saving effect.The 3rd, good dedusting effect of the present invention, 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 present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes 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, 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 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, discharge of the coke control of dust main 2 and discharge of the coke and be provided with electric butterfly valve between control of dust main 2, the control of dust main 2 that wherein discharges of the coke is made of fixing flap valve.
When equilibrium valve is opened, when entering control of dust main 2, air can produce noise, and 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 above-mentioned coke discharging and dedusting main, above-mentioned coke discharging and dedusting main end is provided with equilibrium valve, above-mentioned coke discharging and dedusting main inside is provided with expansion joint, and above-mentioned discharge of the coke control of dust main and above-mentioned the discharging of the coke are provided with electric butterfly valve between the control of dust main.
