Abstract
The utility model provides a vertical coke discharging and smelting furnace with a built-in smoke guiding channel. The built-in smoke guiding channel comprises a channel main body and a 'saddle-shaped' valve; channel openings are respectively formed in a pair of side surfaces of the channel main body; a crossing channel is formed in the channel main body and is connected with the channel openings in two sides of the channel main body; the 'saddle-shaped' valve is arranged on the top of the crossing channel; the crossing channel can be opened or closed by the 'saddle-shaped' valve; and the built-in smoke guiding channel can be applied to a coal side-loading type vertical coke discharging and smelting furnace with single-side/double-side gas collecting tubes, a coal top-loading type vertical coke discharging and smelting furnace with single-side/double-side gas collecting tubes or a double-cavity type coke smelting furnace. By the smoke guiding channel in a furnace body, smoke which is suddenly increased during coal loading and coke discharging of a carbonization chamber is guided into an adjacent carbonization chamber, high-pressure ammonium hydroxide is sprayed to a bridge duct of the adjacent carbonization chamber, the smoke is injected to a gas collecting tube, a phenomenon that the smoke overflows outwards due to the fact that the pressure of the coal loading and coke discharging carbonization chamber is over high is avoided, and the problem that the smoke overflows outwards and heat is lost is solved fundamentally.
Description
Technical field
The present invention relates to have built-in vertical coke discharging pit kiln of leading cigarette channel, belong to metallurgical industry coking industry coking technology field, the fume and dust of leading that is applicable to coke oven coaling and discharges of the coke in process.
Background technology
Existing pit kiln divides and has top coaling two types, conventional pit kiln and side-arranged tamping pit kiln according to the mode of coalingging, top shove charge be at coking chamber top, coaling, side direction discharges of the coke; Side shove charge side direction is coaling, side direction is discharged of the coke.For fear of pit kiln, in the environmental pollution of coalingging and the discharging of the coke in process, the measure of taking is supporting construction range hood, dust removing station, the flue dust that suction is coaling and the coking chamber corresponding site that discharges of the coke is revealed; Simultaneously coaling and the bridge tube of the coking chamber that discharges of the coke on spray high pressure aqua ammonia, flue dust is drawn in effuser.From Germany, introduced in the last few years the furnace roof smoke guiding bogie of " inverted U-shaped " pipe or " m shape " pipe, for side shove charge, when coalingging and discharge of the coke, lead fume and dust, smoke guiding bogie is " inverted U-shaped " pipe or the insertion of " m shape " pipe is coaling and the hole of coalingging of coaling hole and the adjacent coking chamber at the coking chamber top of the discharging of the coke, by " inverted U-shaped " pipe or " m shape " pipe coalingging and discharge of the coke coking chamber and adjacent coking chamber form and lead cigarette channel, to the flue dust of coalingging and the coking chamber that discharges of the coke produces is imported to adjacent coking chamber, and spray high pressure aqua ammonia on the bridge tube of adjacent coking chamber, flue dust is drawn in effuser, prevent from coalingging and the excessive flue dust of pressure of the coking chamber that discharges of the coke excessive.
As can be seen here, the shove charge of existing top is being coaling and is being discharged of the coke in process, auxiliary range hood, the dust removing station built, employing be passive smoke and dust eliminating method, when operation, also there is flue dust leakage phenomenon; The way that side shove charge utilizes furnace roof reserved coaling hole and smoke guiding bogie to lead cigarette is unreasonable, the leak point and the heat radiation point that have increased pit kiln, need accessory machinery, also has pollution, calorific loss problem in operating process, the equipment increasing has increased pit kiln investment, complicated operation.

" inverted-V-shaped " passage of take is example, and built-in " inverted-V-shaped " leads the process of coalingging that cigarette channel is applied to the various vertical coke discharging formula pit kiln of Transverse Heated:
As shown in Fig. 3-12: the discharging of the coke of novel Transverse Heated, vertical coke discharging formula pit kiln is to lean on self gravitation from what arrange, and whole coke discharging process is to carry out in airtight coke disposal, so, do not need to enable built-in " inverted-V-shaped " and lead cigarette channel.But, in the process of coalingging, need to enable built-in " inverted-V-shaped " and lead cigarette channel.In the process of coalingging, apply built-in " inverted-V-shaped " and lead the method for cigarette channel:
When coalingging, open the fire door of pusher side, close the fire door of coke side, the coal charger of pusher side puts into briquette slave wing furnace door 11 to coking chamber 1, and because the integral body of briquette enters, the gas in coking chamber is squeezed, and gaseous tension can increase; Because briquette enters, briquette periphery is near the rapid pyrolysis of coal charge of coking chamber simultaneously, and gaseous tension can increase.Now open " saddle type " valve 32 at coking chamber top, make the gas in coking chamber 1 by the built-in cigarette channel of leading, to be diffused into rapidly the adjacent coking chamber 1 in front and back rapidly, reduce the air pressure of this coking chamber, the coking chamber that unlatching is coaling simultaneously and the high pressure aqua ammonia valve on the coking chamber bridge tube 15 before and after it, flue dust injection, in effuser 16, is prevented to the flue dust of this coking chamber is to external diffusion.
The situation of coalingging for top, closes the fire door of pusher side, coke side, opens the charging hole lid of furnace roof, and the coal charger of furnace roof packs coking chamber 1 by the hole of coalingging into coal charge, and due to entering suddenly of coal charge, the gas in coking chamber is squeezed, and gaseous tension can increase; While, near the rapid pyrolysis of coal charge of coking chamber, gaseous tension can increase because coal charge enters.Now open " saddle type " valve 32 at coking chamber top, make the gas in coking chamber 1 by the built-in cigarette channel of leading, to be diffused into rapidly the adjacent coking chamber 1 in front and back rapidly, reduce the air pressure of this coking chamber, the coking chamber that unlatching is coaling simultaneously and the high pressure aqua ammonia valve on the coking chamber bridge tube before and after it, flue dust injection, in effuser, is prevented to the flue dust of this coking chamber is to external diffusion.
At top of combustion chamber, built-in between coking chamber " inverted-V-shaped " leads cigarette channel, can be according to the mode of coalingging and the discharging of the coke, the top shove charge hole number of coalingging, in the middle of coking chamber, whether cut apart, the facilities of pusher side, coke side effuser and determining, each coking chamber can arrange 2-4 built-in " inverted-V-shapeds " and lead cigarette channel.General side coal, side direction are discharged of the coke, and in the middle of coking chamber, have the wall of cutting apart, and pusher side, coke side are established single effuser, and built-in " inverted-V-shaped " led cigarette channel and can be arranged more; And top shove charge, vertical coke discharging are not cut apart wall in the middle of coking chamber, pusher side, coke side are established double collecting main, and built-in " inverted-V-shaped " led cigarette channel and can be arranged less.
Built-in " inverted-V-shaped " led cigarette channel device and selected carbon material to make.The built-in cigarette channel of leading is designed to " inverted-V-shaped ", and two sections of left and right angle that passage is is less than 60 degree, and design is mainly that the landing of particulate matter nature, avoids passage to stop up in order to allow the passage can laying dust like this.
