Description
Technical field:
The utility model relates to lime stone production fields, and in particular to the limekiln in a kind of PVC Production Process.
Background technique:
The production method of polyvinyl chloride is mainly carbide, and calcium carbide used in carbide is by lime and carbon raw material
It is produced by furnace of calcium carbide, the beam-type limekiln of lime burning is the key equipment in PVC Production Process, beam type stone
Feed inlet, preheating zone, burning zone, cooling zone and discharge port are set as in ash furnace kiln body from top to bottom.Existing beam-type limekiln, In
Upper and lower two layers of burning beam is housed on burning zone, there is the burning pipeline connecting with fuel filler tube, and burning pipeline in burning beam
Combustion air channel between beam body is passed through in fuel filler tube and to be mixed by fine coal, natural gas and calcium carbide stove exhaust
Burning gases, burning gases burning provide heat for limekiln calcining, and burning gases enter kiln by the nozzle of burning beam bottom end
It is interior.Periphery burner is installed on the outside of kiln wall, burning gases, to additional heat on the inside of kiln wall, are made close to kiln wall by periphery burner
Lime stone can be heated calcining.There are following problems in limekiln after long-time service:
1, the heat that periphery burner provides only increases in burner exit, is not radiated to whole kiln wall, more heat
Amount is lost outside kiln wall, and heat can not completely arrive at kiln wall, and then causes calcining belt temperature insufficient, is generated fluctuation, is influenced stone
Lime stone is in the normal reaction of burning zone, the case where there is also raw burn close to the lime stone of kiln wall.
2, refractory brick is relatively thin in kiln at the burner of periphery, and temperature aggregation keeps the refractory brick of periphery burner easy to fall off, service life
It reduces.
3, contain a large amount of lime stone dust in the exhaust gas of limekiln discharge, the lime stone of larger particles can rush in dust
Brushing bag dust collector, causes bag filter to damage, so that dust removing effects substantially reduce, the exhaust gas discharge containing lime stone dust
Into air, to air born pollution, for a long time, so that limekiln periphery accumulates dust, operating environment is polluted, to operation people
The physical and mental health of member has an impact.
Utility model content:
The purpose of this utility model is to provide a kind of limekilns of the reduction heat losses in PVC Production Process.
The utility model is implemented by following technical solution:
A kind of limekiln in PVC Production Process, including kiln body, the kiln body top are equipped with feed inlet, and bottom end is set
There is discharge port, be equipped with preheating zone, burning zone and cooling zone inside the kiln body from top to bottom, the preheating zone top is equipped with upper suction
Gas beam, the burning zone top are equipped with upper layer burning beam, and the burning zone lower part is equipped with lower layer's burning beam, the cooling zone top
Equipped with lower suction beam, the gas outlet of the upper suction beam and the air inlet of air preheater are connected, and the air preheater goes out
Port is connect with the cyclone separator air inlet inside cooling cyclone, the gas outlet of the cyclone separator and bag filter
Air inlet connection；The gas outlet of the lower suction beam is connect with the air inlet of lower suction beam deduster, and the lower suction beam removes
The gas outlet of dirt device is connect with the air inlet of main combustion fan, gas outlet and the air preheater of the main combustion fan
The cold medium outlet of cold medium import connection, the air preheater passes through the kiln body where snorkel and the burning zone
Inside connection.
Preferably, the upper layer burning beam quantity is 1~4, and lower layer's burning beam quantity is 1~3, the upper layer
The both ends of burning beam and lower layer's burning beam are plugged with burning pipeline, and the burning pipeline bottom end is equipped with several groups nozzle,
The upper layer burning beam of nozzle lower end described in every group, the bottom end of lower layer's burning beam are correspondingly arranged 1 through nozzle hole.
Preferably, nozzle quantity described in every group is 1~3.
Preferably, the cooling cyclone includes the cyclone separator, and the cyclone separator outer cup is equipped with collet,
Medium entrance is equipped on the collet of the air inlet side of the cyclone separator, in the gas outlet of the cyclone separator
The collet of side is equipped with media outlet, and the medium entrance is connect with the air inlet of secondary combustion fan, and the medium goes out
Mouth is connect with the snorkel.
Preferably, the cooling tube of head and the tail closure connection, the cooling are fixed with along the discharge port top of the kiln body
Pipe is in rectangle, and the air inlet of the cooling tube and the gas outlet of air blower connect, set along its length on the inside of the cooling tube
It is equipped with 1 lateral cooling tube, its width direction of lateral edge is provided with 2 longitudinal cooling tubes, the cooling tube, cross in the cooling tube
It is interconnected to cooling tube and longitudinal cooling tube, it is opposite between the cooling tube, lateral cooling tube and longitudinal cooling tube
Side is equipped with several cooling gas outlets.
The advantages of the utility model:
1, it is dried, can be exchanged heat with exhaust gas between collet and cyclone separator using secondary combustion fan, and by heat supplement
Burning is participated in into kiln, reduces the thermal losses of limekiln burning zone；And heat exchange jacket and cyclone separator are combined together,
Reduce space hold.
2, periphery burner is removed, kiln wall inner lining refractory material is built completely, prevents inner lining refractory material from falling off, has increased considerably stone
Ash furnace service life reduces thermal loss.
3, cyclone separator can remove the lime stone dust of larger particles in removing exhaust gas, avoid the damage of bag filter,
Reduction exhaust gas is mingled with lime stone dust and is discharged in air, to air born pollution, avoids producing the physical and mental health of operating personnel
It is raw to influence.
