Abstract
The utility model discloses an enamel extruded spiral finned tube economizer, which comprises two end plates arranged oppositely, a plurality of radiating pipes are arranged between the two end plates, each radiating pipe comprises a main pipe provided with spiral fins outside, and enamel layers are coated on outer surfaces of the spiral fins and the main pipes. The economizer effectively avoids low-temperature corrosion and has service life which is 1.5-2times longer than smooth pipes. Compared with a smooth-pipe type economizer, the enamel extruded spiral finned tube economizer expands heat exchanging area greatly, thereby expanding heat transfer area thereof and enhancing heat exchanging effect.
Description
Technical field
The utility model relates to a kind of economizer, relates to a kind of enamel squash type spiral fin coil economizer specifically, belongs to the economizer technical field.
Background technology
Economizer is indispensable parts of modern boiler, and its effect is exactly the feedwater that utilizes the heat heating boiler of boiler tail flue gas, reduces heat loss due to exhaust gas.Economizer in the market mostly adopts light pipe formula economizer and two kinds of structures of high frequency welded spiral fin tube economizer, though light pipe formula economizer is in light weight, volume is little, heating surface is little, heat-transfer effect is poor, erosion corrosion is serious; The high frequency welded spiral fin tube economizer is compared with light pipe formula economizer, expanded heating surface area, heat-transfer effect is better than light pipe formula economizer, but because fin and female pipe are two body structures, there is bigger thermal resistance in the two, and the fold that the helical fin winding forms easily produces dust stratification, stifled ash, sealing-off, fracture phenomena.
The utility model content
Problem to be solved in the utility model is the defective at above-mentioned economizer, and the enamel squash type spiral fin coil economizer that a kind of heat-transfer effect is good, be difficult for dust stratification, wear-resistant, anticorrosive, long service life is provided.
For addressing the above problem, the utility model by the following technical solutions:
A kind of enamel squash type spiral fin coil economizer, comprise the two end plates that is oppositely arranged, between two end plates, be provided with some radiating tubes, described radiating tube comprises female pipe, outside at female pipe is provided with helical fin, it is characterized in that: all coating has enamel layer on the outer surface of helical fin and female pipe.
Below be that the utility model is got to further improvement to such scheme:
Described some radiating tubes are evenly arranged on end plate, and its end communicates in twos by bend pipe.
Described female pipe is steel pipe, described helical fin and the one-body molded setting of female pipe.
The thickness of described enamel layer is 0.34 ± 0.06mm.
The utility model adopts such scheme, compares with light pipe, the high frequency welding spiral fin tube economizer of present routine, has the following advantages:
1, corrosion-resistant.Owing to coat the corrosion resistant enamel of one deck at the helical fin tube outer surface, this economizer has been avoided the cold end corrosion problem effectively, and service life is than 1.5～2 times of optical tube lengths;
2, good effect of heat exchange.Compare with light pipe formula economizer, the spiral fin coil economizer behind the enamel has been expanded heat exchange area significantly, thereby the heat transfer area of economizer is increased, and the heat exchange effect strengthens;
3, resistance to wear.Helical fin in the such scheme can adopt rolling the making of whole blank roll extrusion, dense internal organization, and case hardness improves, and vitreous enamel has anti-wear performance in addition, so enamel squash type spiral fin coil economizer antiwear property strengthens greatly;
4, Heat stability is good.Helical fin has thoroughly been eliminated welded type fin and the thermal contact resistance of female pipe disome and the sealing-off that causes owing to thermal coefficient of expansion is different, fracture phenomena, so heat transfer coefficient and heat endurance be greatly improved;
5, intensity height.The intensive analysis of squash type finned tube is shown that the pipe of this form is 3 times of light pipe with comparing ability to bear with the light pipe of wall thickness such as internal diameter approaching by test and theoretical two aspects.So, be enough with its intensity of economizer tube of this pipe boiler.
6, the dust stratification slagging scorification is few.Because helical fin appearance enamel smooth surface, and fin and female pipe contact site have been eliminated traditional wound form finned tube and have been folded the phenomenon of rough and uneven in surface easy dust stratification slagging scorification because of fin surface with arc-shaped transition.
The utility model is described in further detail below in conjunction with drawings and Examples:
