Abstract

The utility model discloses a heat pipe type air preheater, which comprises supporting legs, a lower cone arranged on the supporting legs, a lower box body arranged on the lower cone, a middle box body arranged on the lower box body, a plurality of heat radiation pipes which are arranged in the middle box body and vertically staggered from one another and an upper box body arranged on the middle box body, wherein the upper parts and the lower parts of the heat radiation pipes are communicated with the upper box body and the lower box body respectively. The heat pipe type air preheater has a compact structure, a small maintenance amount, high sealing property, high heat conduction capacity, high transmission capacity, high safety and long service life, occupies a small area, works reliably, is convenient to mount, erosion resistant and energy-saving; ash can be prevented from being blocked, air can be prevented from leaking, smoke exhaust temperature is reduced, fuels are saved, and smoke afterheat is used; and the efficiency of a cupola furnace is high. The heat pipe type air preheater can be widely applied to a smoke afterheat utilization system of the cupola furnace.

Description

Heat pipe preheater
Technical field the present invention relates to a kind of heat pipe preheater, can be widely used in the furnace cupola fume afterheat and utilize in the system.
The existing air preheater of background technology after operation a period of time, can be found serious cold end corrosion, stifled ash and the problem of leaking out in the heating surface fume side of low-temperature zone, and service life of equipment is low.
Summary of the invention the object of the present invention is to provide that a kind of compact conformation, floor space are little, reliable operation, little, easy for installation, corrosion-resistant, the anti-blocking ash of maintenance capacity, good airproof performance, anti-ly leak out, the capacity of heat transmission is strong, transmittability is big, reduce exhaust gas temperature, the heat pipe preheater of fuel saving, fume afterheat utilization, energy-conservation, high safety, furnace cupola efficient height, long service life.
In order to achieve the above object; Heat pipe preheater of the present invention comprises supporting leg, is installed in the bottom cone on the supporting leg; Be installed in the lower box of cone top, bottom; Be installed in the middle casing of lower box top, several radiating tubes that vertical interlaced is arranged in the casing in being installed in, the upper box of casing top in being installed in; Said several radiating tubes, its top, bottom are communicated with upper box, lower box respectively.
Heat pipe preheater of the present invention, its operation principle is: a side of heating surface through air, is carried out Re Jiaore through flue gas, opposite side, makes air obtain heating, improves temperature, and the flue gas exhaust gas temperature is descended, and improves the degree of utilizing of fume afterheat.Through in the pipe, flue gas vertically flows in pipe flue gas from top to bottom, and then laterally through between pipe, air is lateral flow outside pipe for air, and the heat of flue gas is passed to air through the metal wall, passes to cross-current to heat continuously and crosses the outer air of pipe.Flue gas gets into several radiating tubes after getting into from the top box side, and get into nowel then and discharge from the side, part flue dust wherein, cone is discharged from the bottom under the gravity effect.Simultaneously, cold wind gets into from the raising middle flask bottom sides, and after the radiating tube heat exchange, hot blast therefrom upper box part side is discharged.Like this, the flow direction contrary of flue gas and wind has been strengthened heat-transfer effect, and the capacity of heat transmission is strong, and transmittability is big, and hot blast gets into furnace cupola, can realize the purpose that fume afterheat utilizes.
Heat pipe preheater of the present invention, compact conformation, floor space is little, reliable operation, maintenance capacity is little.Single heat pipe is detachably changed, and safeguards that simply cost is low.
Heat pipe preheater of the present invention, it is not installed and need change existing furnace cupola, and is easy for installation.
Low-temperature corrosion protection and encapsulation process have all been taked in heat pipe preheater of the present invention, the flue gas position of flowing through, and cold end corrosion, stifled ash and the problem of leaking out can not take place, and service life of equipment is long.
Encapsulation process has all been taked in heat pipe preheater of the present invention, the flue gas position of flowing through, and air is walked different passages with the flue gas branch; The heat-transfer area ratio is easier to cleaning; And stopped fully between air and the flue gas leakage with contact, eliminated the possibility that heat pipe preheater catches fire, reduced draw, the pressure fan power consumption; Electricity consumption obtains bigger saving, has also improved the security of furnace cupola operation and the economy of whole therrmodynamic system.
Heat pipe preheater of the present invention utilizes the heat fuel combustion required air of furnace cupola tail flue gas, improves catching fire and burning condition of fuel; Also reduced simultaneously the heat loss due to incomplete combustion; Reduce exhaust gas temperature, fuel saving is to improve furnace cupola efficient.
Heat pipe preheater of the present invention is to utilize fume afterheat to improve the air themperature that gets into burner hearth, and during work, radiating tube is passed to the outer air of pipe with the heat in the flue gas, and it is combustion-supporting that hot-air is used for furnace cupola, improves and overheavy firing.After getting in the stove through the hot-air behind the preheater, quickened fuel drying, catch fire and combustion process, guarantee smooth combustion in the stove, play a part to improve, overheavy firing, thereby reach the purpose of energy savings.Because the stove internal combustion improves and strengthens, add that the hot blast temperature that gets in the stove improves, the mean temperature level also has raising in the stove, thereby can strengthen radiant heat transfer in the stove, plays augmentation of heat transfer.On the one hand, because the stove internal combustion is stable, the reinforcement of radiant heat exchange can reduce loss of the inadequacy burning for chemistry mechanics reason; On the other hand, utilize fume afterheat, further reduced flue gas loss.Therefore, reduce the stove internal loss, reduced exhaust gas temperature, improved boiler thermal output, fuel savings.
In sum, heat pipe preheater of the present invention, compact conformation, floor space is little, reliable operation; Maintenance capacity is little, and is easy for installation, corrosion-resistant, anti-blocking ash, good airproof performance; Anti-leaking out, the capacity of heat transmission is strong, and transmittability is big, reduces exhaust gas temperature, fuel saving; Fume afterheat utilizes, and is energy-conservation, high safety, and furnace cupola efficient is high, long service life.
Description of drawings is done explanation further below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
The specific embodiment is in Fig. 1~Fig. 2; Heat pipe preheater of the present invention comprises supporting leg 1, is installed in the bottom cone 2 on the supporting leg; Be installed in the lower box 3 of cone top, bottom; Be installed in the middle casing 4 of lower box top, several radiating tubes 5 that vertical interlaced is arranged in the casing in being installed in, the upper box 6 of casing top in being installed in; Said several radiating tubes, its top, bottom are communicated with upper box, lower box respectively.
In addition, among the figure, gas approach a, exhanst gas outlet b, cold wind import c, hot-blast outlet d.
