Abstract
The utility model discloses a high-efficiency water heating boiler and water heating machine set, which supplies hot water for heating, sanitation and technology. The utility model makes smoke pipes (5) be arranged on the surrounding of a furnace chamber (1) through changing the structure arrangement; the smoke pipes (5) are arranged in a ring shape; a heat exchanger (8) of annular hot coal water-circulation water is arranged between the furnace chamber (1) and the smoke pipe (5); a water outlet and a water return connection boxes (6, 7) are respectively arranged on the upper side and the lower side of the furnace chamber (1). Meanwhile, the utility model adopts the smoke pipes (5) with high efficiency heat transfer; the rear segment of the furnace chamber (1) is provided with a powerful hot pipe (2) for improving heat transfer quantity; the cover plate of a smoke box can be dismounted. Then the heat transfer surface of the utility model is convenient to clean and descale. The utility model can keep high efficiency heat transfer for a long time.
Description
The utility model relates to a kind of efficient hot-water boiler and hot water unit that is used to supply heating, health and Process heat water.Fuel oil and the gas and hot water unit of producing both at home and abroad all belongs to middle-size and small-size low-temperature atmosphere-pressure hot-water boiler at present, can be referred to as hot-water boiler.
Fuel oil, gas normal-pressure hot-water boiler and hot water unit are not subjected to advantages such as declaration and calibrating restriction with its low pollution, security of operation, automaticity height, and replacing traditional coal-fired pressure boiler in recent years just gradually becomes widely used heating, heating equipment.It comprises the water tank of being with heat-insulation layer, burner, burner hearth, smoke box, smoke pipe (cigarette--hydrothermal exchange device) and takes the heat medium water of water, backwater header out of---the recirculated water heat exchanger: recirculated water through heat exchanger to user's heat supply.Assembling heat exchanger does not then become directly-heated type hot-water boiler, hot water unit.Because this heat exchanger separates installation with burner hearth, smoke pipe, distance is bigger between generating surface and the heat supply surface, only can rely on the natural circulation heat transfer of heat medium water.The tight arrangement and the structural limitations that add burner hearth in the upper water box, smoke pipe, heat medium water are difficult for forming desirable, smooth Natural Circulation and convection heat transfer' heat-transfer by convection, and heat transfer efficiency can be very not high.Many hot-water boilers, hot water unit adopt the integral solder water tank, and smoke pipe and heat-exchanger surface are difficult to cleaning and descaling, and the long-time running heat transfer efficiency can obviously descend.
The purpose of this utility model provides a kind of efficient hot-water boiler and hot water unit, and it can improve heat transfer efficiency effectively, reduce heat cost, and easy cleaning and descaling, can keep efficient heat transfer for a long time.
Purpose of the present utility model is achieved in that the topology layout that changes hot-water boiler and hot water unit, smoke pipe is arranged in burner hearth to be arranged on every side in the form of a ring, heat medium water---the recirculated water heat exchanger is contained between burner hearth and the smoke pipe annular, water outlet, the upper and lower both sides of backwater header apportion burner hearth, and the burner hearth back segment is equipped with the heat-flash pipe, smoke pipe then adopts efficient heat conducting tube, and the smoke box cover plate also is detachable.Adopt this compact layout,, have heat conduction and heat radiation simultaneously, can obviously improve heat-transfer effect because heat supply surface spacings such as the generating surface of heat exchanger and burner hearth, smoke pipe not only form convection heat transfer' heat-transfer by convection from extremely near.The backwater header is contained in the water tank lowest part, causes the temperature field of cold lower part and hot upper part in water tank, heat medium water will form along burner hearth, smoke pipe outer wall rise, the opposite Natural Circulation current of two bursts of directions that descend of chamber interior wall downstream.The heat-flash pipe that the burner hearth back segment is installed not only helps to cause turbulent combustion, strengthens between flame and heat medium water and conduct heat, and also can form the hot water jet pipe, accelerates the circulation rate of heat medium water.The forced circulation current form convection heat transfer' heat-transfer by convection in the Natural Circulation current of heat medium water and the heat exchanger, and heat output also can increase.As cigarette---the smoke pipe of hydrothermal exchange device adopts rolling gilled tube, bellows or other efficient heat conducting tubes, is intended to strengthen heat transfer area, increases heat output.Adopt detachable smoke box cover plate, be convenient to regularly heating surface be carried out cleaning and descaling, keep efficient heat transfer for a long time.It can install 1 to 3 group of heat exchanger, and temperature, the hot water of different purposes is provided respectively, and also assembling heat exchanger not becomes directly-heated type hot-water boiler, hot water unit, and the heating agent water tank then becomes cyclic water tank.
The utility model is compared with existing fuel oil, gas-fired water heating boiler and hot water unit, has that compact conformation, efficient heat transfer, fuel consumption and operating cost are low, easy cleaning scale removal, long-time running heat capacity can not descend the degradation advantage.
Accompanying drawing 1 is the horizontal section structural representation of the utility model embodiment; Fig. 2 is the longitudinal profile schematic diagram.
By burner (11) ejection atomized fuel---air Mixture is burnt in burner hearth (1), behind the heat medium water in the flame heat burner hearth outside and the heat-flash pipe (2), high-temperature flue gas enters smoke pipe (5) by back smoke box (4), after finishing heat exchange with heat medium water, low-temperature flue gas flows into front smoke box (3), enters atmosphere through chimney.Recirculated water enters annular heat medium water through backwater header (7)---and recirculated water heat exchanger (8) imports out water manifold (6) and sends into the hot water line after being heated.Water tank (9) external application heat-insulation layer, front smoke box cover plate (10) is detachable, is convenient to smoke pipe, smoke box cleaning and descaling.Do not adorn heat medium water---recirculated water heat exchanger (8) then becomes directly-heated type hot-water boiler, hot water unit.
Claims (3)
1. an efficient hot-water boiler and hot water unit that is used to supply heating, health and Process heat water, its wraps burner, burner hearth, smoke box, smoke pipe, takes the heat medium water of water and backwater header out of---the water tank of recirculated water heat exchanger, band heat-insulation layer, it is characterized in that smoke pipe is distributed in burner hearth and arranges in the form of a ring on every side, heat medium water---the recirculated water heat exchanger is between burner hearth and smoke pipe, water outlet, the upper and lower both sides of backwater header apportion burner hearth, the burner hearth back segment is equipped with the heat-flash pipe, and the smoke box cover plate is detachable.
2. hot-water boiler according to claim 1 and hot water unit is characterized in that smoke pipe adopts efficient heat conducting tube.
3. hot-water boiler according to claim 1 and hot water unit is characterized in that installing 1 to 3 group of heat medium water---recirculated water heat exchanger, perhaps do not adorn heat medium water---and the recirculated water heat exchanger becomes directly-heated type hot-water boiler, hot water unit.
