Technical field
The utility model relates to a kind of energy-saving heat recovery tamping formula pit kiln, and it belongs to a kind of clean type heat recovery tamping type coking device.
Background technology
Heat recovery tamping formula coking technology is one of international coking new technology, has obtained the extensive approval of international coking circle and actively application.The main advantage one of heat recovery tamping formula pit kiln is to adopt micro-negative pressure operation at coke making process, the volatile matter material that coking produces all burns, and has eliminated coke oven loss of oxious component in process of coking and has caused pollution to environment.The 2nd, coke strenth height, lumpiness are big, can produce high quality metallurgical coke and bulk foundry coke.The 3rd, because coking chamber is wide coking chamber, the shove charge coal can be allocated more hard coal or weak caking coal into, has enlarged the resource of coking coal.The 4th, reclaim the heat that the volatile matter material all burns and produces in the process of coking, produce steam by waste heat boiler, steam can generate electricity or use it for anything else.This coking technology has been realized the recycle of energy resource to a great extent, has improved economic benefit of enterprises.
But heat recovery tamping formula pit kiln is because the caping of bottom fire channel combustion chamber is polygon structure, and its thickness is big at present, and thermo-efficiency is low; Setting device is not set, the suction of uncontrollable adjacent coking chamber coking and temperature in the flue intercommunicating pore.Therefore, there is the technological deficiency that coking time is long, coke oven is transferred fire difficulty, oven door sealing difference in existing heat recovery tamping formula pit kiln.
Summary of the invention
The purpose of this utility model is to solve existing heat recovery tamping formula pit kiln to have the technological deficiency that coking time is long, coke oven is transferred fiery difficulty and oven door sealing difference, provides that a kind of coking time shortens, coke oven transfers that fire is convenient, the energy-saving heat recovery tamping formula pit kiln of fire door and protecting sheet place good airproof performance.
The utility model for the technical scheme that solves above-mentioned technological difficulties and adopt is: energy-saving heat recovery tamping formula pit kiln, it comprises some coking chambers, coke oven furnace roof, flue, bottom fire channel and furnace bottom secondary air blast inlet, wherein: bottom fire channel combustion chamber caping is arc-shaped structure, the secondary air blast inlet is with the control air output at the bottom of coke oven machine side and coke side are respectively arranged with two-deck oven, be provided with the cloth air port of several double-deck reducings at furnace bottom to reduce systemic resistance, in the flue intercommunicating pore, be provided with setting device to regulate coking chamber suction and temperature.
Be provided with wedge shape hold-down gear or spring locking latches at coke oven door.
Described bottom fire channel is any one in six arches or the tetrad arch formula.
The refractory brick of the very useful arc-shaped structure of described bottom fire channel combustion chamber lid is built into.
Described setting device bottom is provided with through hole.
Described wedge shape hold-down gear is made of upper backup pad, lower supporting plate and wedge lock plate; one end of upper backup pad is located at the top of protecting sheet; one end of lower supporting plate is located at the middle and lower part of protecting sheet and the below that lower supporting plate is positioned at upper backup pad; at a distance of the distance of a fire door stationary shaft diameter, be locked between upper backup pad and the lower supporting plate in the locking hole of wedge lock plate insertion upper backup pad the other end setting and with the fire door stationary shaft between the two.
Described spring locking latches is made of pressing plate, spring and spring bracing; spring bracing is made up of perpendicular back up pad and horizontal support plate; one end of spring bracing is located on the protecting sheet; one end of pressing plate is hinged on centre one side on the perpendicular back up pad top of spring bracing and pressing plate is rotatablely moved; spring be located at pressing plate and spring bracing horizontal support plate between and the lower end of spring be contained on the spring bracing horizontal support plate, the bottom connection of the upper end of spring and the pressing plate the other end touches.
Because the utility model has adopted technique scheme, structure and the material of former six arches or tetrad arch place caping brick have been changed, improved the production efficiency of heat transfer efficiency and the coke oven of coke oven combustion chamber, when coking coal briquette thickness is 1000 millimeters coking time had been shortened in 60 hours.Furnace bottom secondary air blast inlet is located at coke oven machine side and coke side can be controlled air output respectively, preheated air, and the coking temperature that can regulate control combustion chamber pusher side and coke side combustion chamber, chamber temperature is more easy to control, makes the coke uniformly ripening.Adopt setting device at adjacent two coking chamber flue intercommunicating pore places, except regulating the coking chamber suction by existing suction setting device, suction and the temperature of adjacent two coking chambers in the process of coking more can be effectively controlled in the adjusting that utilizes the setting device at intercommunicating pore place to carry out adjacent coking chamber suction in process of coking.No matter the coking chamber fire door is a fire door or two fire doors up and down; when coal-charging pushing, to open; to close after having pushed away Jiao or having adorned coal; former fire door will be opened through the mode that make progress---outwards moving---upwards moves;---forward---downward mode is closed again through downwards; compress sealed strip by deadweight, in the whole process of door opening and closing, be easy to sealing material with fire door and protecting sheet place like this and cause wearing and tearing even drop.The utility model has changed that fire door is fixed and compressing structure; fire door only need move horizontally in the process that opens and closes, the wearing and tearing of having avoided sealed strip between fire door and protecting sheet with drop, reduced the loss of anti-material; the sealing that has increased fire door is revised, and has solved burner both sides briquette Jiao's problem.
Therefore compare with background technology, have following advantage:
1, the utility model six arches encircle the structure that the caping brick adopts circular arc with tetrad, have reduced caping thickness, have accelerated the furnace bottom heat transfer, can improve coking rate more than 10%, thereby shorten the coking cycle in 60 hours.Also make coking energy-conservation more than 10%.
2, the utility model furnace bottom secondary air blast inlet is located at coke oven machine side and coke side can be controlled air output respectively, preheated air, and the coking temperature that can regulate control pusher side and coke side combustion chamber, the coking temperature head of coke oven machine side and coke side combustion chamber is about 20 ℃.
3, the utility model has increased setting device at adjacent two coking chamber flue intercommunicating pore places, can better control suction and the temperature of adjacent coking chamber coking, improve the coking chamber temperature as early as possible and the phase is reduced coking chamber suction at coking end at the coking initial stage as far as possible easilier.
4, the utility model has changed switching mode and the fixed form of fire door; solved fundamentally that sealing material damages easily between fire door and the protecting sheet; cause poorly sealed shortcoming, reduced the air capacity that enters coking chamber from fire door, reduced the scaling loss of coking coal.
