Description
Technical field
The present invention relates to calcium carbide processing technology field, specifically a kind of grey processing of furnace of calcium carbide purification is followed with nitrogen recycling
Loop system.
Background technology
It is the net cold water pipes of calcium carbide furnace gas, dust tar settling bin in closed calcium carbide furnace production process that furnace of calcium carbide, which purifies ash,
Cooling-sedimentation and cloth bag bin are gathered dust the particle dust of generation.Calcium carbide per ton about generates 60kg purification ashes in calcium carbide production process.
Since the grey temperature of purification is high (180-200 DEG C), and contain intrinsic carbon and other spontaneous combustion elements, after contacting with the air easily
Fire it is explosive there are great security risks, while purifying that ash particle specific area is big, is insoluble in water, and there is certain viscosity,
Serious dust pollution is caused to ambient enviroment during unloading ash and transporting, generally use Geldart-D particle system is transported in short distance
Furnace of calcium carbide can be purified ash and carry out effective airtight transportation, do not made moist, to extraneous pollution-free by system.
Due to the special physico-chemical property of furnace of calcium carbide purification ash, conveying air source uses nitrogen, the method for operation to be pumped for storehouse close alternate
Disconnected conveying, roll-over during material is sent by air-transport system during material enters with nitrogen after roll-over, carry out gas solid separation, point
Gas pressure substantially micro-positive pressure from after, dust-laden nitrogen is by the deduster filtering discharge at the top of feed bin, the nitrogen after conveying
It is emptied after dust separation, because nitrogen preparation system energy consumption is higher (by production 1m3The nitrogen of purity 99% needs 2.5-3m3Pressure
Contracting air).And recycle 1m3The power consumption of the nitrogen of purity 99% is produce nitrogen 50% or so.It is produced into for enterprise with reducing
This, needs one kind being simple and efficient energy-efficient nitrogen recycling cyclic utilization system.
The present invention is exactly to provide a kind of nitrogen recycling circulatory system to solve deficiencies of the prior art, because
Nitrogen preparation system energy consumption is higher (by production 1m3The nitrogen of purity 99% needs 2.5-3m3Compressed air).And recycle 1m3It is pure
The power consumption of the nitrogen of degree 99% is produce nitrogen 50% or so, saves 50% energy, and needs to empty after purifying useless
It abandons in nitrogen and is entrained with the dust of 13 μm or so of diameter, have greater environmental impacts, all recycling recycles to discarded nitrogen, will disappear
Except this pollution to air.
The technical scheme adopted by the invention to solve the technical problem is that：
A kind of nitrogen recycling circulatory system, characterized in that including gas supply part, air treatment section, gas storage part, gas supply
Part is separately connected air treatment section and gas storage part by pipeline, and air treatment section passes through piping connection gas storage part；
The gas supply part point includes deduster, high pressure positive blower, user's air source, and deduster is defeated by piping connection high pressure positive blower
Enter end, user's air source passes through valve and piping connection high pressure positive blower input terminal；
Deduster is the deduster at the top of feed bin, and the nitrogen that will be discarded passes through pipeline to high pressure positive blower, high-pressure blast
Machine provides the power run in recovery system for nitrogen.Setting emptying desorption tube on house outlet pipeline, when nitrogen recycling system
It unites after deactivating or overhauling when first used, unqualified air direct emission in system.
The air treatment section includes cooler, filter, and high pressure positive blower output end passes through piping connection cooler, institute
It states cooler and passes through piping connection filter；Pipeline setting desorption tube and gas analysis and Control instrument in high pressure positive blower exit, when
Nitrogen oxygen concentration is exceeded, opens desorption tube emptying；Nitrogen dust content meets gas quality.
The gas storage part includes buffering equipment, compressor, gas storage equipment, and the filter passes through piping connection to buffering
Equipment, the buffering equipment are set by piping connection to compressor, compressor by piping connection to gas storage equipment, the gas storage
It is standby to pass through piping connection to output channel；User's air source passes through piping connection to output channel.User's air source passes through decompression
Tonifying Qi valve group provides the unstability for discarding nitrogen to high pressure positive blower deduster, while by piping connection to output channel, mending
The circulatory system is repaid to die when repairing or the case where when air pressure shakiness.
Nitrogen compressor pressurization after enter gas storage equipment, through gas storage equipment buffer voltage stabilizing after, directly by output channel into
Enter the total pipe network of nitrogen circulation, increase valve and flow, pressure detecting at existing docking output channel, meets the normal steady of system
Fixed operation.
The gas supply part further includes decompression tonifying Qi valve group, and wind turbine protects valve group, and user's air source is by depressurizing tonifying Qi
Valve group and piping connection high pressure positive blower input terminal；The wind turbine protection valve group is in parallel with high pressure positive blower, the high pressure positive blower output
End is additionally provided with gas analysis controller.
Nitrogen through deduster filtering discharge is by high pressure positive blower pipeline through cooler (conveying temperature of charge 180-200
DEG C), filter filtering after lead to gas reservoir, to adapt to the intermitten service of Dense Phase Pneumatic Conveying；On house outlet pipeline
Setting emptying desorption tube, after nitrogen recycling system deactivates or overhauls when first used, unqualified air direct emission in system；
High pressure positive blower inlet and outlet are arranged in parallel wind turbine protection valve group, and negative pressure occurs in pipeline before preventing high pressure positive blower, leads to equipment damage；

The buffering equipment is buffer air bag, air accumulator or gas storage holder is one such or several combinations.
The electrical equipments such as pneumatic operated valve and gas analysis controller are by control system and related accessories control operation.
The beneficial effects of the invention are as follows：
1, because nitrogen preparation system energy consumption is higher (by production 1m3The nitrogen of purity 99% needs 2.5-3m3Compression it is empty
Gas).And recycle 1m3The power consumption of the nitrogen of purity 99% is produce nitrogen 50% or so, saves 50% energy, and purify
The dust for being entrained with 13 μm or so of diameter in the discarded nitrogen emptied is needed afterwards, is had greater environmental impacts, it is whole to discarded nitrogen
Recycling cycle, will eliminate this pollution to air.
2, user's bleed pressure is 0.5-0.6MPa, needs to be depressurized to slightly above atmospheric pressure when at high pressure positive blower,
So needing to use decompressor, the present invention replaces common pressure reducing valve by the way of depressurizing tonifying Qi valve group.Depressurize tonifying Qi valve group
It is located among two pneumatic operated valves using pressure reducing valve series connection and forms reducer unit, another pneumatic operated valve mould in parallel with the reducer unit
Formula, when pressure reducing valve damage needs repairing, closing and concatenated two pneumatic operated valves of pressure reducing valve partially open parallel connection therewith
Pneumatic operated valve can both repair replacement pressure reducing valve, not influence system operation, and safety greatly improves.
3, wind turbine protects valve unit protection high pressure positive blower, breaks down or depressurize what tonifying Qi valve group broke down in deduster
When, wind turbine protection valve group can form temporary self-loopa with high pressure positive blower, to protect high pressure positive blower to damage.
4, due to from deduster come out nitrogen pressure fluctuation it is larger, so setting buffering equipment ensure that it is subsequent
Compressor works normally.
