Description
Technical field
The present invention relates to environmental protection technical field, and in particular to a kind of flue heat sink.
Background technology
It is domestic at present metallurgy, building materials, electric power, chemical industry flue gas ash removal mostly be to use dry-method bag-type dedusting, but cigarette
Temperature degree is usually higher, and before entering bag filter and carrying out dedusting, temperature should be cooled to no more than 200 high-temperature flue gas
DEG C, to avoid the cloth bag of bag filter is burnt out.
The domestic various heat sinks of generally use cool down high-temperature flue gas, and heat sink is divided into air-cooled and water cooling
Formula, but the contact of water or wind as cooling with high-temperature flue gas is mediate contact, causes cooling velocity slower.
The content of the invention
It is an object of the invention to provide a kind of flue heat sink, and to solve, existing heat sink cooling velocity is slow to ask
Topic.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of flue heat sink, including the water cooling tube being affixed on flue outer wall and the air cooled lamp being affixed in flue inner wall,
The water cooling tube is connected with air cooled lamp, further includes the supporting rod being arranged in flue, several companies are rotatably connected on supporting rod
Extension bar, is installed with several porous coal briquettes in connecting rod, several porous coal briquettes are distributed along connecting rod length direction, the air cooling

Water cooling tube is affixed on flue outer wall, is used for realization the first step cooling to flue gas, flue gas is after water cooling tube, water cooling tube
In cold water be changed into hot water, since water cooling tube is connected with air cooled lamp and pipeline, a part of hot water enters in air cooled lamp, another portion
Hot water is divided to enter in driving pipeline, after the dry ice in air cooled lamp runs into hot water, gasification immediately produces great amount of carbon dioxide cold air, in fact
Now the second step of flue gas is cooled down, after carbon dioxide is contacted with porous coal briquette, C+CO occurs2The endothermic reaction of=2CO, realization pair
The 3rd step cooling of flue gas, rotates, wheel rotation passes through transmission mechanism band into the hot water in driving pipeline for impeller
Dynamic connecting rod rotates, and makes porous coal briquette axis rotation centered on connecting rod in connecting rod, due to smoke movement direction all the time not
Become, during porous coal revolutions, the outer surface of porous coal briquette can be arrived with smoke contacts, i.e., porous coal briquette can be with the dioxy in flue gas
Change carbon gas to come into full contact with, due to the loose structure inside porous coal briquette so that carbon and carbon dioxide in porous coal briquette
Contact area increases, and reaction is more abundant.
Following technique effect can be reached using this programme：
1st, dry ice gasifies and is directly to be contacted with flue gas, realizes the fast cooling to flue；
2nd, porous coal revolutions, can make outer surface energy and the carbon dioxide reaction of porous coal briquette, and reaction is more abundant, by
In porous coal briquette with being rotated during carbon dioxide reaction, so as to be deformed caused by avoiding the local reaction of porous coal briquette, can keep
The shape of porous coal briquette；
3rd, the contact area of carbon and carbon dioxide in porous coal briquette can be increased using porous coal briquette, reaction is more filled
Point；
4th, carbon after carbon dioxide gas precursor reactant with producing the high carbon monoxide of utility value in porous coal briquette, after collecting
Used as the reducing gas on metallurgy；
5th, water cooling tube has triple role, can realize the preliminary cooling to flue, the water side heat face of discharge can make dry ice
Gasification, moreover it is possible to which impeller is so as to drive porous coal revolutions；
6th, contacted since porous coal briquette relies on to rotate with carbon dioxide, impact of the carbon dioxide to porous coal briquette
Power is smaller and than more uniform, and porous coal briquette will not fall slag, because without the problem of porous coal briquette carbon distribution and carbon granules remain occurs.
Further, transmission mechanism includes chain.Chain drive is suitable for hot environment, and it is low speed rotation that connecting rod, which rotates,
It is dynamic, it is adapted to use chain drive.
Further, water cooling tube and air cooled lamp are detachably connected.Easy to which air cooled lamp is disassembled, dry ice is supplemented.
Further, the sedimentation plate being arranged in flue is further included.Settled beneficial to bulky grain flue dust, avoid bulky grain flue dust from existing
Move in flue, cause damage to flue inner wall, extend the service life of flue.
Further, sliding bearing is equipped between connecting rod and supporting rod, sliding bearing is externally provided with protection cap.Sliding bearing
The friction between connecting rod and supporting rod can be reduced, since connecting rod is equipped with multiple porous coal briquettes so that connecting rod and support
There is larger axial force, sliding bearing can bear large axial force, avoid that phase occurs between connecting rod and supporting rod between bar
To sliding.
Further, recovery channel is further included, recovery channel both ends are connected with flue, and recovery channel both ends are located at respectively
Porous coal briquette both sides.Using recovery channel can by flue not completely with porous coal briquette reaction carbon dioxide again with it is more
Hole coal briquette reacts, and improves the utilization rate of carbon dioxide.
Further, connecting pipe is communicated between water cooling tube and air cooled lamp, connecting pipe is equipped with flow control valve.Flow
Control valve is used to adjust the amount for entering hot water in air cooled lamp from water cooling tube.
Further, air cooled lamp is made of heat-resistant aluminium alloy material.Since air cooled lamp is located in flue, heat-resisting aluminium alloy energy
Prevent air cooled lamp deformed damaged, moreover it is possible to prevent air cooled lamp by flue gas corrosion.
