Background technology
In the incineration treatment of garbage process, for waste of low heating value is better burnt, guarantee that the combustion air that enters the incinerator burner hearth remains on stable temperature, combustion air must be through after the air preheater heating, just can send into incinerator.
Existing air preheat method adopts fume afterheat, contains steam and sulfuric acid vapor in the flue gas, and condition of work is more abominable, occurs cold end corrosion and stifled ash easily.In case cold end corrosion and stifled ash take place, will cause exhaust gases passes to stop up, the air inducing resistance increases, boiler positive pressuring combustion, this has not only reduced boiler output, even causes and be forced to blowing out.The result of corrosion can cause the air preheater pipe to reveal and damage, and causes seriously and leaks out, and causes that combustion conditions worsens, and the heating surface of having to often change when serious had both increased maintenance load and spillage of material, had influenced the normal operation of boiler again.Cold air enters fume side, also can reduce the cigarette temperature, quickens the speed of cold end corrosion and stifled ash, thereby influences the safe operation of boiler, reduces service life of equipment greatly, and flue gas is revealed also can cause environmental pollution.
Adopt steam preheating just can solve above problem, but existing vapor preheater adopts the coiled heat exchanger tube, its condensed water that produces when low temperature amasss in pipe bent position, has increased steam by the resistance that pipe bent position is subjected to, and influences the heat exchange effect.And during the preheater that heat exchange area is very big if desired, the preheater manufacturing of said structure, installation and transportation are all very inconvenient.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of split type steam type airheater, to solve technical problems such as original preheater manufacturing, installation and transportation inconvenience.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of split type steam type airheater, has body structure, casing is provided with air inlet and air outlet, be provided with two bringing-up sections in the casing, comprise high pressure section and low pressure stage, bringing-up section comprises some set of heat exchange tubes, every group of heat exchanger tube comprises the vertical tube of two rows transverse tube and two horizontal row Guan Shangcheng rectangular arranged, the group with the group between or between the bringing-up section employing box flange be connected, casing outside upper and lower side is respectively arranged with steam inlet pipe and steam outlet pipe, this advances, the effect of steam outlet pipe is similar to the collection case, and described two horizontal row pipes are communicated with steam inlet pipe and steam outlet pipe respectively.
For volume that reduces casing and the service efficiency that improves preheater, further: the transverse tube that respectively is provided with two rows of mutually staggered on steam inlet pipe and the steam outlet pipe respectively.
In order to prevent the shake in the heat exchanger course of work, further: band steel support fixation heat exchanger tube is set in the casing of preheater.
For the water that steam cooling back is formed can better flow out, further: form certain angle between steam outlet pipe and the horizontal plane, angular range is 1-5 °.
For equipment being carried out the periodic maintenance cleaning, further: be provided with the maintenance section between high pressure section and low pressure stage, the maintenance section is provided with inspection manhole and blow device.
For air is distributed fast, reach the effect of uniform heat exchange, further: the air inlet place in casing is provided with the deflector that air is distributed fast.
The beneficial effects of the utility model: adopt the split-type structural design because preheater is inner, when making large-scale preheater, can make set of heat exchange tubes simultaneously, assemble again at last, reduce manufacturing time, and detachably get off during transportation, very convenient.
