Description
Technical field
This utility model relates to spherical ore deposit heating, drying equipment, a kind of tunnel for the calcining of spherical phosphorus powder ore deposit
Kiln.
Background technology
Mud phosphorus is calcined by the most commonly used stationary kiln being or rotary kiln, by mud phosphorus in the case of ingress of air
In element phosphor be oxidized to P2O5, then absorb P2O5 with water and make the phosphoric acid (H3PO4) of mass fraction 65%-75%, generally between
Formula of having a rest feeds, but the wherein mass fraction of element phosphor still difficult meet the requirement of environmental protection, the mass fraction of the P2O5 of residual reach 22%～
26%, it is still desirable to subsequent treatment.
Tunnel cave is usually a long linear tunnel, and fixing wall and vault are arranged at its both sides and top, and bottom spreads
If track on run kiln car.Combustion apparatus is located at the both sides, middle part of tunnel cave, constitutes fixing thermal zone--clinkering zone,
The high-temperature flue gas that burning produces, under the effect of tunnel cave front end chimney or air-introduced machine, flows along tunnel to kiln hood direction, with
Time preheat the goods entered in kiln step by step, this section constitutes the preheating zone of tunnel cave.Kiln tail at tunnel cave blasts cold wind,
The goods of latter one section in cooling tunnel kiln, after the cold wind blasted flows through goods and is heated, then extract feeding exsiccator out as dry
The thermal source of dry green compact, this section just constitutes the cooling zone of tunnel cave.
High-temperature gas in kiln is all through Base top contact to outside, and kiln body a problem is that entrance the most now
One end of kiln body and the one end going out kiln body, in general temperature reduces, and is the most just unfavorable for the heating in spherical ore deposit, high-temperature gas
Also can not get effectively utilizing, cause the waste of the energy, be unfavorable for the energy-saving and emission-reduction of equipment.Also have when harassing exactly and need to carry
For large quantity of air, cold air is directly entered and is also detrimental to temperature heating, and high-temperature gas is typically all and directly guides away.
Summary of the invention
In order to overcome the disadvantages mentioned above of prior art, this utility model provides one to make full use of high-temperature gas in tunnel cave
Preheating kiln body two ends in advance, also preheat in advance air to be entered simultaneously, thus can guarantee that supercooled air is not
Enter in kiln body or mixing combustible gas heats together and can improve utilizing status, reach the effect of energy-saving and emission-reduction, fall
Low production cost improves the tunnel cave for the calcining of spherical phosphorus powder ore deposit of energy utilization rate.
This utility model solves its technical problem and be the technical scheme is that a kind of tunnel for the calcining of spherical phosphorus powder ore deposit
Road kiln, including burner hearth, furnace bottom, kiln body and calcining frame, burner hearth is a having furnace bottom and kiln body to surround, and bottom of furnace body is arranged
Having track, kiln body is near the position inner hollow of inlet and outlet, and upper end connects, in kiln body with the guiding blower fan at kiln body top
Empty portion envelops lives the inlet and outlet of kiln body, and the import of kiln body hollow space, near furnace bottom position, is finally pooled to kiln body top
Portion, the passage along top reaches to be positioned at the guiding blower fan of kiln body top center.
It is provided with in the hollow space of described kiln body and adds hot-air duct, add hot-air duct and be finally linked into combustion gas gas
Inside mix.Hollow also acts the effect of insulation in actual use, and the introducing of hollow structure changes high temperature tail
The emission path tail gas of gas is incorporated into the inlet and outlet of kiln body, and the kiln body problem of such inlet and outlet is just incubated, profit
Heat insulation effect is reached with high-temperature tail gas.Meanwhile, so the air that the combustible gas such as coal gas need is utilized the high temperature tail discharged
Gas preheats in purging line, thus substantially increases the efficiency of burning, thus reduces the loss of the energy.
Described adding, is linked into outside hot-air duct in oxygen permeable membrane device.The oxygen gas component of air is fixing, is combined with
The oxygen permeable membrane device of differential pressure principle prepares oxygen-enriched air, and due to gas-fired mainly by oxygen, so burning is the most abundant,
Reduce the usage amount of the energy, well reach energy-saving and emission-reduction.
Being circular bottom described calcining frame, and be provided with teeth, the teeth on adjacent calcining frame are intermeshed.Calcining frame is adopted
Use such structure, in calcination process, so just can rotate calcining frame, being heated more of the spherical phosphorus powder ore deposit in this sample rack
The most fully, it is only necessary to drive an outmost calcining frame can rotate all of calcining frame successively, it is to avoid directly to drive and forge
Buck needs to consider high-temperature heat-resistance equipment, which decreases improvement cost.
Described guiding blower fan is positioned at the middle part of vertical evacuated tube, is respectively provided with two arms and kiln body bottom distance evacuated tube
The hollow space connection at two ends, guides and arranges drainage screen below blower fan.So guiding blower fan in evacuation procedure, dust granules is just
Fall bottom evacuated tube, be so convenient to clean and reclaim.
This utility model has the advantages that the high-temperature tail gas utilizing calcining to produce, and coordinates and sets in inlet and outlet
Put hollow layer, solve kiln body export and import temperature the most very well the lowest, the problem of heat insulation effect difference；Utilize zone of heating simultaneously
The air needed is carried out preheating and is effectively increased efficiency of combustion；Coordinate teeth to realize the rotation of calcining frame simultaneously, the most effective
Solving calcining frame upper part spherical phosphorus powder ore deposit to be heated uneven problem, improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of evacuated tube of the present utility model.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
