Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of efficient boiler coal-saving device.
Efficient boiler coal-saving device of the present utility model, by housing, flue and heat exchanger tube are formed, snakelike flue is provided with in housing, snakelike flue enter the both sides that mouth and outlet flue lay respectively at housing, snakelike flue is provided with wedge shape vacuum heat exchanger tube, wedge shape vacuum heat exchanger tube is through the tube wall of snakelike flue, the short end of wedge shape vacuum heat exchanger tube is positioned at the inner side of snakelike flue, its long limit end is positioned at the outside of snakelike flue, the duct wall of snakelike flue lowest part is provided with dust-exhausting port, the outer wall of housing is provided with water inlet and delivery port, the top of housing is provided with valve opening, automatic exhaust steam valve is provided with in valve opening.
As further improvement of the utility model, described automatic exhaust steam valve is made up of ball and spring, described round-bead seat in the valve opening of housing, the compact heap that one end of spring props up ball, the other end props up valve opening inwall.
As further improvement of the utility model, the duct wall of described snakelike flue lowest part is cone-shaped, and dust-exhausting port is positioned in the minimum point of cone.
As further improvement of the utility model, in described snakelike flue, be provided with microcirculation water pipe, the two ends of microcirculation water pipe and the inner chamber UNICOM of housing.
As further improvement of the utility model, described enter mouth and outlet flue is funnel-form.
As further improvement of the utility model, the bottom of described housing is provided with lower margin.
Efficient boiler coal-saving device of the present utility model, selects snakelike flue, extends the heat-exchange time of flue and aqueous medium; Its wedge shape vacuum heat exchanger tube arranged, adds heat exchange area; Its funnel-form outlet flue and enter mouth, also extends the time of staying of high temperature smoke in flue, and then improves heat exchange efficiency; Its microcirculation water pipe set up can make the current in housing produce the temperature difference, makes from the aqueous medium temperature of delivery port outflow more even; The taper tube wall of its lowest part makes the dedusting in smoke convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is automatic exhaust steam valve structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, efficient boiler coal-saving device of the present utility model, is be made up of housing 1, flue and heat exchanger tube, is provided with snakelike flue 2 in housing 1, snakelike flue 2 enter the both sides that mouth 3 and outlet flue 4 lay respectively at housing 1, enter mouth 3 and be all connected flue collector with outlet flue 4; Enter mouth 3 and outlet flue 4 is funnel-form, the inlet end entering mouth 3 is thin mouth end, outlet side is thick mouth end, the inlet end of outlet flue 4 is thick mouth end, outlet side is thin mouth end, and this import and export design can extend the time of staying of high temperature smoke in flue, improves heat exchange efficiency; Snakelike flue 2 is provided with wedge shape vacuum heat exchanger tube 5, wedge shape vacuum heat exchanger tube 5 is through the tube wall of snakelike flue 2, the outside that the short end of wedge shape vacuum heat exchanger tube 5 is positioned at the inner side of snakelike flue 2, its long limit end is positioned at snakelike flue 2, which increase the heat exchange area of heat exchanger tube, and then improve heat exchange efficiency; The duct wall of snakelike flue 2 lowest part is cone-shaped, dust-exhausting port 6 is positioned in the minimum point of cone, and the turning of each bottom is equipped with dust-exhausting port 6, this taper tube wall design makes flue dust be accumulated to dust-exhausting port 6 along tube wall, facilitates dust discharge, avoids dust accretions flue; Be provided with microcirculation water pipe 14 in snakelike flue 2, the two ends of microcirculation water pipe 14 and the inner chamber UNICOM of housing 1, the microcirculation water pipe 14 set up can make the current in housing produce the temperature difference, makes from the aqueous medium temperature of delivery port outflow more even; The outer wall of housing 1 is provided with water inlet 7 and delivery port 8, and water inlet 7 connects water source, delivery port 8 connect boiler feed water import, by heat up after water inject boiler; The bottom of housing 1 is provided with lower margin 10, for stablizing whole device; The top of housing 1 is provided with valve opening 9, automatic exhaust steam valve is provided with in valve opening 9, when intaking or when water temperature raises water body expansion, for pressure release, its automatic exhaust steam valve is made up of ball 11 and spring 12, described ball 11 is in the valve opening 9 of housing, one end of spring 12 props up ball 11, the other end props up the compact heap 13(of valve opening 9 inwall as Fig. 2), when housing 1 inside produces certain pressure, pressure can by ball 11 jack-up, after earth pressure release is complete, ball 11 can be pushed up back original position by spring 12, and is closed by valve opening 9.
