Abstract
The utility model relates to a high-efficiency energy-saving multi-return hot water stove. A water area between a left and a right pattern boards (2), (11), a water area outside a tail smoke chamber (13) and water areas outside other smoke chambers are simultaneously divided into two areas by a cross partition board (7) which is arranged between a last-return smoke tube group and other smoke tube groups. A cold water inlet (21) is positioned outside the tail smoke chamber above the partition board, and a hot water outlet (10) is arranged below the partition board. The utility model implements the purpose that water flow exchanges heat by means of adverse flow at a low temperature smoke gas area and by means of mixed flow at a high temperature smoke gas area. The utility model greatly enhances heat exchange effect, and the heat efficiency reaches to 93.7%.
Description
The utility model relates to energy-efficient many backhauls fuel oil (combustion gas) water heater that uses light diesel fuel or liquefied petroleum gas, coal gas etc. to act as a fuel.
Many backhauls of disclosed horizontal smoke pipe fuel oil (combustion gas) water heater, flue gas adopts 3～4 backhauls, water-cooled wetting back-type structure is adopted in the furnace wall, though strengthened heat exchange area, yet cold water is introduced from the body of heater bottom usually, hot water is drawn from top, be the downflow type heat exchange mode, thereby the thermal efficiency can only reach about 85% usually.
Main purpose of the present utility model is to improve the flow direction of water in stove, make current in the low-temperature flue gas district with the reflux type heat exchange, in the high-temperature flue gas district with the mixed flowing mode heat exchange.Heat exchange efficiency is improved greatly, can prevent again that chamber wall temperature is too low and cause carbon deposit, reach energy-efficient purpose.
The utility model is realized its purpose as follows: in the end the diaphragm plate 7 between backhaul smoke pipe group and other smoke pipe group will be separated into two zones between the pool between left and right sides card 2 and 11, tail smoke-box pool, 13 outside and the pool, other smoke-box outside simultaneously.Cold water inlet 21 is positioned at the outside of diaphragm plate top, tail smoke-box, and hot water outlet 10 is below diaphragm plate.There is muscle sheet 8 in each smoke-box outside.
Water heater cold water of the present utility model is introduced directly into to the tail smoke-box outside, flows through last backhaul smoke pipe group more all around with the reflux type heat exchange, flows into the body of heater bottom then with mixed flowing mode and combustion chamber and bottom smoke pipe group heat exchange, so thermal efficiency height.Detect through Guangxi Zhuang Autonomous Region product quality supervision and testing institute.The thermal efficiency reaches 93.7%.
Embodiment further specifies the utility model below in conjunction with accompanying drawing.
Fig. 1 is the embodiment profile that the utility model is used for horizontal three backhaul water heaters.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the embodiment profile that the utility model is used for vertical horizontal smoke pipe four backhaul water heaters.
Fig. 4 is the A-A profile of Fig. 3.
No matter be horizontal (as Fig. 1) or vertical (as Fig. 3) water heater, combustion chamber 3 levels are contained in insulation furnace shell 4 bottoms, and smoke pipe group 14,16 and 20 all is horizontally disposed with, and the end links to each other by smoke-box.Combustion flame sprays into combustion chamber 3(this moment to the right by burner 1 during use, flue gas is first backhaul), become high-temperature flue gas through first smoke-box, 5 turnings, 180 degree then and enter the second backhaul smoke pipe group 16, enter the 3rd backhaul smoke pipe group 14 through second smoke-box, 9 turnings, 180 degree again, horizontal water heater flue gas backhaul for Fig. 1 is three backhauls, and flue gas enters tail smoke-box 13 at last; Vertical horizontal smoke pipe water heater flue gas backhaul for Fig. 3 is four backhauls, and its flue gas is than the many backhauls of horizontal chamber furnace (oven), enters tail smoke-box 13 by smoke pipe group 14 180 degree of turning again through the 4th backhaul smoke pipe group 20; Flue gas is discharged by chimney 12 at last.In Fig. 1, the diaphragm plate 7 of restriction current is contained in the pool that includes the second backhaul smoke pipe group 16 and includes between the pool of the 3rd backhaul smoke pipe group 14, cold water enters the outer rear flank of tail smoke-box 13 through cold water inlet 21 from water inlet pipe 6, water hole 22 on right card 11 cylindricals enters the pool, top that includes smoke pipe group 14, and the cigarette G﹠W carries out countercurrent heat exchange in this district.The water hole 15 of water after the heating on left card 2 cylindricals, the bottom that flows to stove along the outside of smoke-box 9 enter around the combustion chamber 3 and include the pool of smoke pipe group 16, flow out from hot water outlet 10 after the mixed flow heat exchange.
In Fig. 3, diaphragm plate 7 is contained in the pool that includes the 4th backhaul smoke pipe group 20 and includes between the pool of the 3rd backhaul smoke pipe group 14.Cold water enters tail smoke-box 13 outer rear flank by water inlet pipe 6 and enters the pool, top that includes smoke pipe group 20 by the aperture 15 on the left card 2 again and carry out countercurrent heat exchange, enter the outside of smoke-box 17 again through the water hole 22 on the right card 11, again through being contained in mozzle 19 on the small baffle 18 and the water hole on the right card, enter include smoke pipe group 16 and 14 and the pool, bottom of combustion chamber 3 carry out the mixed flow heat exchange, flow out from hot water outlet 10 the heating back.
Also being provided with the muscle sheet 8 vertical with water (flow) direction in smoke-box water side, is the mechanical strength that increases heat exchange area and smoke-box on the one hand, makes current simultaneously when the smoke-box surface, and the muscle sheet makes the current that are the advection state become turbulent condition, to strengthen the heat exchange effect.
Claims (2)
1, a kind of energy-efficient water heater, comprise furnace shell, combustion chamber, smoke pipe group, card and smoke-box, it is characterized in that in the end the diaphragm plate (7) between the backhaul smoke pipe group and other smoke pipe group simultaneously will the pool between left and right sides card (2), (11), be separated into two zones between the pool outside pool, tail smoke-box (13) outside and other smoke-box; Cold water inlet (21) is positioned at the outside of diaphragm plate top, tail smoke-box, and hot water outlet 10 is below diaphragm plate.
