Embodiment

A kind of new section coal coke oven, comprise coke oven base 1, place the concrete furnace bottom 2 on the coke oven base, place on the concrete furnace bottom, the body of heater 3 that has vision slit 20 and thermometer hole 21, place intravital flue of stove and coking chamber 4, be located at the furnace body outer wall bottom, lead to flue, gas pipe 23 runs through coal gas hand-hole 5 wherein, place the coal gas at flue top to portal 6, be located between flue and the coking chamber, between flue and the furnace wall, flue body of wall 7 between coking chamber and the furnace wall, place the hole 8 of coalingging at coking chamber top, be located in the furnace body outer wall, place coal gas hand-hole bottom, lead to flue, airduct 24 runs through cold wind hole wherein, the coke export 10 of being located at furnace body outer wall and communicating with coking chamber; Flue comprises first heat preservation zone 11 that places the body of heater bottom, places second heat preservation zone 12 of body of heater middle and lower part, places the 3rd heat preservation zone 13 of body of heater middle and upper part, places the 4th heat preservation zone 14 of upper of furnace body, and each heat preservation zone is connected by logical fire hole 15; Place coking chamber and the exhaust smoke hole 16 of the junction, hole of coalingging, coking chamber is connected with the 4th heat preservation zone of flue; Coke export is two outlets that run through the coking chamber bottom, run through the body of heater bottom.

For easily that refining in the stove is good coke takes out from fire door, can on the concrete furnace bottom, open a top trough 25, and communicate with the flue bottom, be provided with top machine 26 in the groove.Described top machine is meant that the top has the whisky jack of steel fork 27.Because coke is bonding in stove, so when coming out of the stove, if by force coke is released, then might influence the performances such as granularity of coke, therefore in stove, when coming out of the stove, with the top machine coke jack-up in the stove is come earlier, the fork sheet 30 of steel fork inserts in the coke, and then slowly the top machine is put down, the bonding coke that so just loosened is convenient to come out of the stove.(speed such as caving machine down is too fast in order to prevent error in when operation, also influence the performances such as granularity of coke), available one pushes away fork 28 cooperates the top machines to use, and fork sheet 29 width that push away fork equate with gap between the fork sheet of steel fork, like this, the top machine is when coke jack-up is come in the stove, in the gap between the fork sheet of the fork sheet insertion steel fork that pushes away fork, again the top machine is put down, then, to push away fork and from coke, extract out, thereby avoid the unnecessary loss that causes because of misoperation.

In order to make the coking chamber thermally equivalent, several flues can be set evenly around coking chamber.

Can directly several gas pipes be inserted flue by the coal gas hand-hole.Be economical with materials, one outboard tube cornice can there be external arm 17, connects the ring pipe of arm 18 around being located at the furnace body outer wall bottom in having with the corresponding inboard tube wall of coal gas manhole place, and connecing arm in inciting somebody to action by in the coal gas hand-hole insertion flue, the external arm on the ring pipe is connected with outside coal gas source.External arm can be several, in to connect the arm number identical with the flue number.

Airduct same gas pipe is set.

In order to lower the temperature to furnace body outer wall, can one water for cooling device be set at furnace body outer wall, this device can be: furnace body outer wall is designed to the interlayer furnace wall, and water inlet pipe is introduced interlayer 22 in the bottom of furnace body outer wall, interlayer is introduced with rising pipe in top at furnace body outer wall, water inlet pipe, the same water tank that has water circle device of rising pipe are communicated, can realize lowering the temperature to furnace body outer wall.For uniform decrease in temperature, can several water inlet pipes evenly be set around furnace body outer wall, and several rising pipes of arrange accordingly.This device also can be: have external arm 17, inside tube cornice to connect the annular conduit of arm 18 around the upper and lower part of being located at furnace body outer wall in having one outboard tube cornice, and connect in inciting somebody to action in the arm insertion interlayer, be located at external arm on the annular conduit on top of furnace body outer wall as rising pipe, be located at external arm on the annular conduit of bottom of furnace body outer wall as water inlet pipe.External arm, in connect arm and all can be several.This device can also be: directly with an annular conduit around the top of being located at furnace body outer wall, and dig out some apertures in the bottom of annular conduit, coke oven is when work, and is dirty along furnace body outer wall from the water that aperture is discharged, and also can realize lowering the temperature to furnace body outer wall.

Certainly, utilize the prior art of water to the furnace body outer wall cooling, specification sheets of the present utility model can not be enumerated it one by one, but those skilled in the art understands that necessarily these prior aries are also contained in the utility model.

Because water temperature in temperature-fall period raises, can be used for resident's heating.

Because moulded coal mixes back compression moulding by coal dust with water, moulded coal enters when coalingging the hole moisture higher, and the aperture preheating of coalingging, temperature is very high, therefore can make the water evaporates in the moulded coal, and the evaporation of moisture content, the refining of coke that one side is convenient, but then, in evaporation vapour, can have dusty gas inevitably, if allow evaporation vapour all emerge from the hole of coalingging, then same contaminate environment, so for will evaporate vapour also can be all from the coal gas discharge of portalling, and then all reclaim, also can leave exhaust hole 31 on the hole wall of coalingging, exhaust hole can feed in the 4th heat preservation zone, also can feed during coal gas portals.

In order to make body of heater have advantages of higher stability and heat retaining property, can be square furnace with Proper Design; Coking chamber is a rectangular parallelepiped; It perhaps is the small truncated rectangular pyramids of the gradient; Flue is evenly distributed on around the coking chamber, and each heat preservation zone in the flue is all rectangular parallelepiped.In order to improve coke quality, according to the order of heat preservation zone, promptly to the 4th heat preservation zone, the height of each heat preservation zone can successively decrease according to this, and the height of first heat preservation zone can be coal gas hand-hole two times to the distance of bottom of furnace body.Logical fire hole is by special-shaped siliceous brick of existing horizontal block or the vertical special-shaped siliceous brick refractory brick that make, that have three apertures 32 of building.
