Description
Technical field
The utility model belongs to activated carbon making apparatus field, and in particular to a kind of tail gas of carbonization stove secondary combustion chamber is special
Oxygen-supplying tube.
Background technology
Raw material is carbonized in retort high temperature, can generate the carbon containing tail gas of a large amount of high temperature, and meeting will be high in activated carbon producting factory
The waste heat of warm tail gas recycles, for manufacturing high-temperature steam.To make full use of waste heat from tail gas, also the carbon dust wherein contained is fired
It burns, its heat is discharged, so needing secondary combustion chamber.
Secondary combustion chamber is made of combustion chamber and oxygen-supplying tube, since the exhaust temperature just discharged is very high, is had been over
The burning point of carbon dust, is only the absence of comburant oxygen.After oxygen-supplying tube is passed through oxygen, the carbon dust in tail gas can be quick in second-time burning room
Burning, further improves exhaust temperature.But traditional oxygen-supplying tube is only a tube body, the oxygen being passed through is difficult to disperse, office
It is sex-limited big, cause the burning of the carbon dust in tail gas is insufficient to be just discharged, do not utilize waste heat to greatest extent.And carbon dust is fired with it
The ashes of burning easily settle in second-time burning room, it is difficult to clear up.
Utility model content
To solve the problems, such as that more than technology exists, it is special logical that the utility model provides a kind of tail gas of carbonization stove secondary combustion chamber
Oxygen pipe can be passed through oxygen on a large scale, and make secondary combustion chamber inner exhaust gas and be passed through oxygen and be sufficiently mixed, and carbon dust is made fully to burn,
Waste heat is discharged to greatest extent.
Its technical solution is：
A kind of special oxygen-supplying tube of tail gas of carbonization stove secondary combustion chamber, it is curved including vertical tube, horizontal tube, rotary joint and recoil
Pipe, the vertical tube connected with horizontal tube by rotary joint, and the vertical tube the lower section and horizontal tube may be contained within secondary
In combustion chamber, more recoil bend pipes, the recoil bend pipe distal opening, the recoil bend pipe are provided with and communicated on the horizontal tube
It is more than the diameter of recoil bend pipe end with the diameter of horizontal tube junction, the complete direction of bending of all recoil bend pipes is consistent.
The carbon containing tail gas of high temperature enters secondary combustion chamber, while high pressure oxygen is passed through from vertical tube, reaches in horizontal tube, then
It is sprayed out of recoil bend pipe on horizontal tube.Since the diameter of recoil bend pipe and horizontal tube junction is more than recoil bend pipe end
Diameter, and the complete direction for the bend pipe that recoils is consistent, so the recoil strength for the high pressure oxygen that horizontal tube can be ejected pushes rotation, it is real
Lead to oxygen on a large scale in existing second-time burning room, and stir tail gas and be passed through oxygen and be sufficiently mixed, carbon dust is made fully to burn, to greatest extent
Discharge waste heat.
Further, the horizontal tube is provided with polylith rotating plate on the direction of its axis, can stir mixed tail gas and oxygen,
Promote mixing velocity, and prevent carbon dust and the sedimentation of the ashes of its burning.
Further, ring pipe is provided with and communicated on the vertical tube in second-time burning room, the ring pipe is first-class
Angle is provided with multiple gas nozzles.
Vertical tube is set at secondary combustion chamber tail gas upstream end, and the high pressure gas in vertical tube is from the gas nozzle on ring pipe
It sprays, realizes carbon dust oxygen-enriched combusting, and increase logical oxygen range, push the simulation model for mixing gases flows of tail gas and oxygen, improve second-time burning
Efficiency.
Further, air gauge is provided on the vertical tube in outside second-time burning room, it can be according to the pressure on vertical tube
Force value confirms that recoil bend pipe allots the recoil strength of oxygen, so as to confirm whether horizontal tube can rotate.
The beneficial effects of the utility model：
The utility model can be passed through oxygen on a large scale, and make secondary combustion chamber inner exhaust gas and be passed through oxygen and be sufficiently mixed, and make
Carbon dust fully burns, and discharges waste heat to greatest extent, and prevents carbon dust and the sedimentation of the ashes of its burning；Realize carbon dust oxygen-enriched combusting,
The simulation model for mixing gases flows of tail gas and oxygen is pushed, improves second-time burning efficiency.
