Abstract
The utility model relates to a plug-in steam pipe ash discharge hopper heater. Horizontal finned tube rows are welded on the side surface of a vertical steam-water pipeline to form a comb-shaped whole so as to be plugged in an interlayer space at the lower part of an ash hopper, and the horizontal finned tubes are in a certain angle of elevation, wherein one ends of the horizontal finned tube rows are closed, and the horizontal finned tube rows are different in lengths. Steam enters from the upper part of the vertical steam-water pipeline and fills all the finned tube rows so as to conduct natural convection for heat transfer with air outside the tube rows. The steam after radiating is condensed into saturated water which automatically flows back into the steam-water pipeline from finned tube orifices and is finally discharged by a steam trap. The heater is similar to a heat pipe in heat transfer, has a good heat transfer effect and long service life, is convenient and reliable in assembly and maintenance, and is most suitable for remoulding a current ash hopper electrical heating device.
Description
Technical field
The utility model relates to a kind of steam type ash bucket heating arrangement, particularly a kind of plug-in type steam pipe ash bucket temperature booster.
Technical background
The heating of dust collector ash hopper mainly contains electro heat and two kinds of forms of steam heating, general each the ash bucket 5-10KW of heating power.The dust exhaustor of the generating in power plant has 16-48 ash bucket usually, if adopt electro heat, its power consumption is huge, and service expenditure is high, and is very uneconomical.Therefore, power plant all hopes to replace electro heat with steam heating.The steam-heated principle of dust collector ash hopper lets steam condensation heat in the heat exchanger tube of ash bucket interlayer exactly, makes the air themperature of ash bucket interlayer maintain 120-140 ℃, prevents the grey moisture absorption bonding in the ash bucket.The structure of ash bucket steam heater is light pipe coiling formula structure normally, and promptly steam heating pipe is coiled in the interlayer of grey headwall round and round, and steam gets into from top, discharges from the bottom after the heat radiation condensation.There are problems in the steam heater of this coiling structure, mainly is:
1. coiling formula steam heater is not suitable for the heating transformation of old ash bucket, and construction is difficulty too.
2. radiator coils grey headwall, and welding space is narrow and small, and welding quality is difficult to guarantee that steam is prone to leak.
3. the carbonated drink flow velocity is higher in the radiator, can wash away tube wall, shortens the life-span of heating pipe.
4. radiator is a light pipe, and dissipating area is little, and heats is poor.
5. in a single day coil pipe leaks, and maintenance is difficulty very.
Just owing to the above-mentioned defective of coiling formula steam heater, electro heat ash bucket user originally dare not carry out steam-heated reducing energy consumption
Summary of the invention
Be problems such as the constructional difficulties that solves present coiling formula ash bucket steam heater, easy leakage, life-span weak point, heats difference and maintenance difficult; The utility model improves the structure of ash bucket steam heater, has proposed plug-in type steam pipe ash bucket temperature booster.This temperature booster is a kind of pectination of stretching out many parallel fins pipes from a side of carbonated drink pipe, inserts in the ash bucket interlayer along the side of ash bucket interlayer.4 faces of an ash bucket insert the steam heater that 3-4 organizes this pectination usually.This steam heater can be prefabricated in the factory, and can guarantee welding quality, no leak, and site operation is simple, long service life, heats is good, keeps in repair easy.
The technical scheme of the utility model is: different in size, end sealing, an end are made into pectination with the radiator row that the welding of carbonated drink pipe communicates, and the pipe socket of this pectination is gone in the ash bucket interlayer, make transverse finned tube line up certain elevation angle.Steam makes in the pectination heating pipe to be full of steam from the vertical carbonated drink pipe of top entering.Steam carries out the free convection heating through transverse finned tube row to the air in the ash bucket interlayer, heats grey headwall again through hot air.Steam after the heat radiation condenses into condensed water, flows automatically in the vertical carbonated drink pipe.Condensate in each vertical carbonated drink pipe is compiled discharge at last.The heat exchange of comb is similar to the heat exchange of the condensation segment of heat pipe.
The utility model has the advantages that:
1. the pipe of pectination row can be prefabricated in the factory, and welding quality is guaranteed, can not leak.
2. can insert easily in the ash bucket interlayer, easy construction, the ash bucket heating that is particularly suitable for old dust exhaustor is transformed.
3. the heat interchanging area of fin tube structure is big, and heats is good.
4. the heat exchange principle of heat pipe-type can make velocity in pipes extremely low, avoids carbonated drink washing away to put, and increases the service life greatly.
5. pectination is not only convenient inserts, and also is convenient to take out, and therefore maintenance is very easy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Accompanying drawing 2 is the enforcement scheme drawing of the utility model.
In Fig. 1 Fig. 2,1. vertical carbonated drink pipe, 2. transverse finned tube is arranged 3. ash bucket inwalls, 4. ash bucket outer walls, 5. vapor and water separators
The specific embodiment
The utility model is to be the plug-in type pipe ash bucket temperature booster of heating medium with steam.It is managed (1), transverse finned tube row (2), ash bucket inwall (3), ash bucket outer wall (4), vapor and water separator (5) etc. by vertical carbonated drink and forms.
The embodiment of the utility model is: the vertical carbonated drink pipe (1) with temperature booster is welded into pectination with transverse finned tube row (2) earlier; Then transverse finned tube row (2) is inserted in the mezzanine space of ash bucket inwall (3) and ash bucket outer wall (4) formation, and welded closure.The top that steam is managed (1) from vertical carbonated drink gets into; Be full of whole fin tubes rows (2), carry out the heat radiation of free convection, be condensed into saturation water then with the air in the mezzanine space; Inlet along fin tube row (2) flows automatically in the vertical carbonated drink pipe (1), and permanent set water is discharged through vapor and water separator (5).Steam constantly gets into transverse finned tube row (2), and condensate constantly therefrom flows out again, forms the interchange of heat of heat pipe-type, with more than the air heating to 120 in the interlayer ℃.
Claims (2)
1. a plug-in type steam pipe ash bucket temperature booster is made up of vertical carbonated drink pipe and transverse finned tube row etc., and it is characterized in that: the fin tube platoon leader of heat transmission is short to differ, end sealing, and an end communicates with the welding of carbonated drink pipe, becomes the integral body of a pectination.
2. temperature booster according to claim 1 is characterized in that: the transverse finned tube socket is gone in the interlayer enclosure space of ash bucket, becomes a fixed angle of altitude, and condensed water can be flowed automatically in the vertical carbonated drink pipe.
