Description
Technical field
The utility model belongs to condenser technology field, particularly relates to a kind of Novel condenser between boiler energy-saving device and chimney.
Background technology
Day by day in short supply along with the energy, the price of the energy climbs up and up, and considerably increases the production cost of enterprise.Boiler, as the power-equipment of enterprise, adopts fuel combustion to produce hot water or steam, for the production and operation of enterprise provide thermal source.The height of boiler efficiency directly affects the operating cost of enterprise.How reducing exhaust gas temperature, raising the efficiency is the focus that user pays close attention to, the direction that Ye Shi boiler producer makes great efforts.Current boiler tail is provided with energy-saving appliance, and discharge the flue-gas temperature of energy-saving appliance at about 150 DEG C, boiler overall efficiency is about 92%.But also have part sensible heat in flue gas, and a large amount of latent heats of vaporization (mainly contains a large amount of protium in fuel, generates water, exist in the form of water vapor in flue gas after burning.), this part heat accounts for greatly 10% ~ 15% of total amount of heat, therefore considerable.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and a kind of heat of part " low temperature " flue gas of discharging in order to absorption boiler energy-saving appliance is provided, reduce final smog discharge temperature, improve the Novel condenser of boiler thermal output, final is user's economize energy, improves its economy, competitiveness.
The purpose of this utility model has been come by following technical solution.This Novel condenser, comprise wave-fin pipe, casing, described condenser adopts resistant material to be made, and is made up of some row's wave-fin pipes, described wave-fin pipe is made up of pipe and fin, arranges or is staggered in arrangement between this wave-fin pipe in suitable; Upper entrance and the import header of described wave-fin pipe are welded to connect, and lower part outlet and outlet header are welded to connect; The outside of some row's wave-fin pipes is covered by casing, flow between casing and wave-fin pipe for flue gas, wave-fin Bottomhole pressure be current, and flue gas stream becomes reflux type to arrange with current.
As preferably, the fin of described wave-fin pipe is helical form, adopts high-frequency welding manner to be connected and fixed with pipe way; Or utilize thick-walled pipe, adopt rolling mode make fin, fin and pipe way integral; Or the outer pipe of low-durometer material is overlapped at tube exterior, while forming fin by extruding, pipe and exterior material are bonded.
As preferably, the spacing of described fin is 5 ~ 10mm.
The beneficial effects of the utility model are:
1), the outer surface coiling of wave-fin pipe fin, add heating surface area, improve the caloric receptivity of condenser;
2), current become counter-flow arrangement mode with flue gas stream, improve temperature and pressure, thus add caloric receptivity;
3), adopt normal temperature cold water to carry out preheating, be applied in boiler, both improve boiler efficiency, the partial oxidation in water can be removed again, reduce the corrosion to boiler;
4), reduce flue-gas temperature to close to below dew point or dew point, make steam partial condensation in flue gas, can dissolve or carry partial fume impurity in condensation process, as acid, dust etc., thus make flue gas cleaner.

Fig. 2 is wave-fin tubular construction schematic diagram of the present utility model.
Label in accompanying drawing is respectively: 1, import header; 2, wave-fin pipe; 3, casing; 4, outlet header; 5, pipe; 6, fin.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1,2, the utility model comprises wave-fin pipe 2, casing 3, described condenser is made up of some row's wave-fin pipes 2, described wave-fin pipe 2 is made up of pipe 5 and fin 6, arranges or is staggered in arrangement between this wave-fin pipe 2 in suitable; Upper entrance and the import header 1 of described wave-fin pipe 2 are welded to connect, and lower part outlet and outlet header 4 are welded to connect; The outside of some row's wave-fin pipes 2 is covered by casing 3, and what flow between casing 3 and wave-fin pipe 2 is flue gas, and in wave-fin pipe 2, flowing is current, and flue gas stream becomes reflux type to arrange with current; Because in use, the fume side of condenser exists condensed water, can produce certain corrosion to condenser, therefore condenser need select resistant material, as stainless steel, ND steel etc.
The fin 6 of described wave-fin pipe 2 is helical form, and adopts high-frequency welding manner to be connected and fixed between pipe 5; Or utilize thick-walled pipe, and adopt rolling mode to make fin 6, integral between fin 6 and pipe 5; Or at the outer pipe of pipe 5 outer cover low-durometer material, while forming fin 6 by extruding, pipe 5 and exterior material are bonded.Fin mode can increase heating surface, and the area of increase and the height of fin 6, spacing are relevant, are generally 3 ~ 5 times of light pipe.Because the flue-gas temperature of this position is lower, required flow area is less, and therefore the spacing of fin 6 can arrange less, and size is generally 5 ~ 10mm.
The utility model adopts the mode of the wave-fin pipe 2 be made up of fin 6, adds the heat transfer area of condenser, accelerates the absorption of heat, improves heat transfer efficiency; Adopt more closely spaced fin 6, considerably increase heating surface area, and also reduce the volume and weight of condenser, thus make operation more convenient, safer; Structure of the present invention is simple, reasonable in design, also reduces cost of manufacture simultaneously.
Operation principle of the present utility model is: this condenser is arranged between the energy-saving appliance of fuel-oil or fuel-gas boiler and chimney, can carry out at right angle setting or level installation according to on-site actual situations; As level is installed: in in-line arrangement between wave-fin pipe 2; As at right angle setting: in in-line arrangement between wave-fin pipe 2, also can be staggered in arrangement; After part " low temperature " flue gas that boiler energy-saving device is discharged enters condenser, flowed into by the entrance of condenser, through the transversal flow of condenser heating surface, enter flue from the outlet on condenser top after flue gas heat release cooling, finally enter air through chimney; The current of preheating enter from import header 1, and be then assigned to each row's wave-fin pipe 2, current flow from top to bottom in pipe 5 inside, then are pooled to outlet header 4.The dew-point temperature of fuel-oil or fuel-gas boiler is within 100 DEG C, and the current of therefore condenser preheating need adopt cold water.
By use of the present utility model, flue-gas temperature can be made to drop to close to dew point, even below dew point, not only absorb the sensible heat in flue gas, and absorb the latent heat that moisture condensation discharges, thus substantially increase the efficiency of boiler, efficiency can be made to reach 98% ~ 105%, and (efficiency calculation of boiler is undertaken by the low heat valve of fuel, if therefore the latent heat of vaporization is also all utilized, actual efficiency should be about 110%.)。
The utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
