Description
Technical field
The utility model belongs to energy-saving appliance technical field, particularly relates to a kind of energy-saving appliance structure being arranged on boiler plant afterbody.
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.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and a kind of partial fume heat of discharging in order to absorption boiler is provided, reduce final smog discharge temperature, improve the energy-saving appliance structure 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 energy-saving appliance structure, comprises casing, snakelike heating surface tube, and described energy-saving appliance is made up of the snakelike heating surface tube of some rows, in being staggered in arrangement between this snakelike heating surface tube; Upper entrance and the import header of described snakelike heating surface tube are welded to connect, and lower part outlet and outlet header are welded to connect; The outside of the snakelike heating surface tube of some rows is covered by casing, flow between casing and snakelike heating surface tube for gas, snakelike heating surface Bottomhole pressure be current, and gas flow becomes reflux type to arrange with current.
As preferably, the outer wall of described snakelike heating surface tube is wound with Fin sheet, this Fin sheet is helical form, and adopts high-frequency welding manner to be connected and fixed between snakelike heating surface tube; Or utilize thick-walled pipe, and adopt rolling mode to make Fin sheet, integral between Fin sheet and snakelike heating surface tube.
The beneficial effects of the utility model are:
1), the disturbance not only enhancing flue gas stream is staggered in arrangement, and operation length also corresponding increase, therefore improve heat transfer coefficient;
2), snakelike heating surface tube outer surface coiling helix fin, add heating surface area, improve the caloric receptivity of energy-saving appliance;
3), current become counter-flow arrangement mode with flue gas stream, improve temperature and pressure, thus add caloric receptivity;
4), snakelike heating surface tube becomes snakelike trend, adds current length; Decrease current flow area, improve flow velocity, add heat absorption.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Label in accompanying drawing is respectively: 1, import header; 2, snakelike heating surface tube; 3, casing; 4, outlet header; 5, Fin sheet.
Detailed description of the invention
Do detailed introduction below in conjunction with accompanying drawing to the utility model: as shown in accompanying drawing 1,2, the utility model comprises casing 3, snakelike heating surface tube 2, and described energy-saving appliance is made up of the snakelike heating surface tube 2 of some rows, in being staggered in arrangement between this snakelike heating surface tube 2; Upper entrance and the import header 1 of described snakelike heating surface tube 2 are welded to connect, and lower part outlet and outlet header 4 are welded to connect; The outside of the snakelike heating surface tube 2 of some rows is covered by casing 3, and what flow between casing 3 and snakelike heating surface tube 2 is gas, and in snakelike heating surface tube 2, flowing is current, and gas flow becomes reflux type to arrange with current; Like this can heat in absorption flue gas as much as possible.
As shown in Figure 2, concrete trend is (describing from top to bottom) to the trend of single snakelike heating surface tube 2: pipe is horizontal forward, then bends 180 ° to the right and returns, more bending 180 ° of inclined downward of turning right, and angle of inclination is 45 °; Turn left forward more bending 180 ° and return, then bending 180 ° of inclined downward of turning left, angle of inclination is 45 °; Then turn right forward bending 180 ° and return, so repeated multiple times.
The outer wall of described snakelike heating surface tube 2 is wound with Fin sheet 5, and this Fin sheet 5 is helical form, and adopts high-frequency welding manner to be connected and fixed between snakelike heating surface tube 2; Or utilize thick-walled pipe, adopt rolling mode to make between Fin sheet 5, Fin sheet 5 and snakelike heating surface tube 2 integral; Fin sheet mode can increase heating surface, and the area of increase and the height of Fin sheet 5, spacing are relevant, are generally 2 ~ 4 times of light pipe; Therefore, while increase caloric receptivity, the volume of energy-saving appliance can be reduced.
The utility model adopts the mode of the snakelike heating surface tube 2 be made up of Fin sheet 5, adds the heat transfer area of energy-saving appliance, accelerates the absorption of heat, improves heat transfer efficiency.Snakelike heating surface tube 2 adopts this special trend, can reduce the flow area of current, improves flow velocity, also can improve the heat transfer coefficient of current.Wrong row's mode can strengthen the disturbance of flue gas, improves the exothermic coefficient of flue gas.While raising heat transfer, also reduce the volume and weight of energy-saving appliance, 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 energy-saving appliance is arranged on the outlet smoke box of two return or three-pass boiler, be vertically mounted on the top of outlet smoke box, " high temperature " flue gas of boiler is discharged from smoke box upper outlet, flowed into by the entrance of energy-saving appliance bottom, through the transversal flow of energy-saving appliance heating surface, enter flue from energy-saving appliance top after flue gas heat release cooling, finally enter air through chimney; The water of the required heating of boiler, inputted by feed pump, flow into from the import header 1 in the snakelike heating surface tube 2 at energy-saving appliance top, then the snakelike heating surface tube 2 of each row is assigned to, serpentine fashion is become to flow from top to bottom, be pooled to outlet header 4 again, after the water heat absorption in snakelike heating surface tube 2 heats up in input boiler.After adopting this energy-saving appliance, boiler efficiency can improve 3 ~ 6 percentage points.
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.
