The roasting device comprises an air pipe and a roasting gas pipe, and is characterized in that the roasting gas pipe is arranged in the air pipe to form a sleeve structure, one end of the air pipe is sealed, a first air pipe nozzle is arranged on an air pipe wall above the sealed end, a roasting gas pipe nozzle extends out from the air pipe nozzle, a second air pipe nozzle is arranged between a furnace wall and the first air pipe nozzle, and a heat-resisting protective layer is arranged out of the air pipe. The nozzle end of the roasting gas pipe bends relative to an axis of the air pipe to form an angle alpha of 45-60 degrees. An ordinary fuel gas pipe is arranged in the air pipe. The heat-resisting protective layer is a heat-resisting material casted layer. Compared with the prior art, the roasting device of the gas-circulation heating furnace has the advantages of being capable of guaranteeing complete combustion of gas and air, protecting the furnace wall from damage caused by high-temperature flame or partial sudden temperature rise, and needless for replacement of the roasting device during the whole roasting process.
Description
Technical field
The utility model relates to circulating mash gas heating furnace baker field, particularly a kind of circulating mash gas heating furnace furnace drying device.
Background technology
Heat accumulating type circulating mash gas heating furnace is a kind of Thermal Equipment, and heating furnace need be dried body of heater and pipeline before operation.Destructive distillation gas is adopted in the combustion gas of heat accumulating type circulating mash gas heating furnace oven dry usefulness, and destructive distillation gas is the high heating value gas that gas retort produces, and calorific value is big, and ignition temperature is high.Present furnace drying device complex structure, cost height; When using high heating value gas, cause tempering easily; Housing is easy deformation under hot conditions, makes furnace drying device can't satisfy reusable requirement.
Summary of the invention
The purpose of the utility model provides a kind of circulating mash gas heating furnace furnace drying device, overcomes the deficiency of prior art, can guarantee that coal gas and air fully mix completing combustion; Can control furnace temperature, prevent that the apparatus for baking shell from damaging because of local temperature is too high, whole baker process need not changed roaster.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Circulating mash gas heating furnace furnace drying device; Comprise air hose and baker Gas Pipe, said baker Gas Pipe is arranged on and forms sleeve structure in the air hose, and air hose one end is blind dead; Air hose spout one is located at the tube wall top of cecum; Baker Gas Pipe spout is located at air hose spout one place, and air hose spout two is located between furnace wall and the air hose spout one, and air hose is provided with refractory protection outward.
The relative air hose axis bending of said baker Gas Pipe spout end becomes one 45-60 ° angle [alpha].
Be provided with normal coal-fired tracheae in the said air hose, the spout of normal coal-fired tracheae is located at air hose spout one place.
Said air hose spout one place is provided with ignition.
Said refractory protection is the heat proof material pouring layer, is evenly distributed with the anchor studs that prevents that pouring layer from coming off in the pouring layer.
Compared with prior art, the beneficial effect of the utility model is: 1) baker Gas Pipe spout is located at air hose spout one place, can guarantee that coal gas and air fully mix completing combustion.2) air hose spout two forms the low-temperature protection district at the furnace wall place, prevents that thermal-flame or local abrupt temperature rise from damaging furnace wall.3) be provided with refractory protection in apparatus for baking box hat appearance, the apparatus for baking shell is played the effect of protection, whole baker process need not changed roaster.Adopt the electric destructive distillation gas that ignites of striking sparks when 4) baker begins, more safe and reliable than the manual firing.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
See Fig. 1; Be the utility model circulating mash gas heating furnace furnace drying device example structure sketch map, comprise air hose 1 and baker Gas Pipe 6, baker Gas Pipe 6 is arranged on through fixture 9 and forms sleeve structure in the air hose 1; Air hose 1 one ends are blind dead; Air hose spout 1 is located at the tube wall top of cecum, and baker Gas Pipe spout 11 is located at air hose spout one 12 places, and air hose spout 2 10 is located between furnace wall 14 and the air hose spout 1; Between furnace wall and baker flame, form the cryogenic gas protection zone, prevent that thermal-flame or local abrupt temperature rise from damaging furnace wall.Air hose spout one 12 places are provided with ignition 13, and it is safer to light a fire.Also be provided with a normal coal-fired tracheae 5 in the air hose 1, the spout of normal coal-fired tracheae 5 is located at air hose spout one 12 places, in the baker constant temperature stage, has only normal coal-fired tracheae 5 spout places to keep fired state, and as the igniting burning things which may cause a fire disaster that heats up next time.
Air hose 1 is outer to be provided with refractory protection 8, and refractory protection 8 be the heat proof material pouring layer, is evenly distributed with the anchor studs 7 that prevents that pouring layer from coming off in the pouring layer, assurance apparatus for baking operate as normal all the time in the baker process.
Relative air hose 1 axis bending of baker Gas Pipe spout 11 ends becomes one 45-60 ° angle [alpha]; Baker Gas Pipe spout 11 is positioned in the middle of the air hose spout 1; And at a certain angle to around spray coal gas, guarantee that baker combustion gas and air fully mix completing combustion.
This device is located at through flange 3 and bolt 2 on the manhole flange 4 at furnace wall 14 hole places of heating furnace, and normal coal-fired tracheae 5, baker gas pipe 6 and ignition 13 link to each other with corresponding external pipe, promptly accomplish the installation of equipment.
Feed combustion air during baker earlier; Feed the baker combustion gas again, unlocking electronic igniter 13 promptly gets into normal baker program simultaneously; Automatically control coal gas amount and air capacity according to heating curve; In the baker process, need control air, baker combustion gas muzzle velocity greater than tempering speed, prevent that flame from getting into the pipeline internal combustion.
Because of adopting destructive distillation gas to carry out baker, destructive distillation gas is a kind of high heating value gas, and calorific value of gas should adopt the way control furnace temperature of excessive bubbling air near natural gas when baker, and excess air also plays the effect of cooling protection to the apparatus for baking shell simultaneously.
