Aborning,, need to surface cooler be set at the rear of furnace of calcium carbide flue gas is lowered the temperature because temperature is higher from furnace of calcium carbide flue gas out, still, surface cooler is wasted a large amount of fume afterheats in atmosphere, causes the waste of resource.And self exists etching problem surface cooler, service life is shorter, and meanwhile, the more difficult control of surface cooler exit gas temperature, easily causes the deduster that is arranged on its rear to damage, and the problem of the sticky bag of high temperature burning bag and low temperature occurs.
Heat exchanger, is that one can reduce flue-gas temperature, high-temperature flue gas can be utilized again simultaneously, reaches the equipment of heat exchange object.It is generally made up of casing, heat pipe and metal partion (metp), on the inwall of casing, be welded with metal partion (metp), the smoke box that this metal partion (metp) is bottom by the interior separation of casing and be positioned at the heat exchange box on smoke box top, on the casing of smoke box both sides, be respectively arranged with into mouth and outlet flue, on the casing of heat exchange box both sides, be respectively arranged with import and the outlet of cold medium, the heat pipe of longitudinal setting is installed on the plate face of metal partion (metp).If heat exchanger is replaced to the surface cooler in system for producing calcium carbide, so will be from improving to a great extent the utilization ratio of flue gas, the fault rate of reduction whole system.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of design science rationally, improve utilization ratio, reasonable energy utilization, the reduction equipment of flue gas fault rate, be beneficial to productions, the flue gas waste heat of calcium carbide furnace that is easy to realization utilizes system.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of flue gas waste heat of calcium carbide furnace utilizes system, comprise furnace of calcium carbide, heat sink, dust arrester, air-introduced machine and chimney, rear at furnace of calcium carbide is provided with heat sink, be disposed with dust arrester, air-introduced machine and chimney at the rear of heat sink, it is characterized in that: described heat sink is a heat exchange of heat pipe, the mouth that enters of this heat exchange of heat pipe is connected with the exhaust opening of furnace of calcium carbide and the import of dust arrester respectively with outlet flue, is connected with steam turbine generator at the cold media outlet end of heat exchange of heat pipe.
And, on the inwall of described heat exchange of heat pipe casing, be fixed with anticorrosion sheet material by bolt.
And described anticorrosion sheet material is polytetrafluoroethylene (PTFE) sheet material.
And described dust arrester is glass-fiber bagged dust collector.
Advantage of the present utility model and good effect are:
1. this flue gas waste heat of calcium carbide furnace utilizes system, by the surface cooler for reducing flue-gas temperature in traditional flue gas coming from carbide furnace treatment system is replaced with to the heat exchanger with flue gas cool-down and heat recovery, has improved the energy conservation characteristic of whole system.And by with the coordinating of steam turbine generator, reach the object of steam-electric power for production and application.When use, between the maximum operating temperature and dew-point temperature of deduster, select the start-up temperature of a suitable temperature as heat exchanger, thereby further reclaim the waste heat of furnace of calcium carbide outlet flue gas, what ensure deduster enters mouth temperature constant, avoids the damage of deduster.
2. this flue gas waste heat of calcium carbide furnace utilizes system, by anticorrosive PTFE sheet material is set on the inwall of box heat exchanger, has avoided due to smoke components complexity, the problem of the coke dust abrasion smoke box being mingled with in it.
3. the utility model scientific structure design is reasonable, have advantages of utilization ratio, the reasonable energy utilization, the reduction equipment that improve flue gas fault rate, be beneficial to productions, be easy to realization, be that a kind of flue gas waste heat of calcium carbide furnace with higher innovation utilizes system.
