Abstract
The utility model relates to an improved structure of a publicly known spray-type atmospheric water heating boiler. A water spraying device is arranged in a boiler body, the end of a water inlet pipe of the water spraying device is penetrated through the boiler body and connected and arranged on a water supply pipe by an internal-circulation booster pump, and a water return pipe of the water spraying device is connected to a water-cooled wall of a combustion chamber. When the utility model works, water in a boiler is sent into the water spraying device by the inner-circulation booster pump, and sufficient heat exchange is processed by water droplets (mist) ejected by the water spraying device and high-temperature and high-speed smoke gas generated by the combustion chamber to heat the water in the boiler. The utility model has the advantages of simple structure, convenient operation, low cost, high thermal efficiency, etc.
Description
Affiliated technical field
The utility model belongs to the combustion apparatus technical field, relates to a kind of high-efficiency and energy-saving type atmospheric hot-water boiler.
Background technology
The main body of present known normal-pressure hot-water boiler generally is made up of the body of heater that contains storage tank, combustion apparatus, water-cooling wall, convection bank, economizer, air preheater etc., mode with heat radiation, convection current, conduction is carried out heat exchange, and its exchange process is gas (high-temperature flue gas that produces during burning) → solid (steel of heat-exchange surface) → liquid (hot water).The height of this mode of heating thermal efficiency and the speed of firing rate all depend on the size of heat-transfer area, the inside and outside high-temperature flue gas of height, the temperature difference inside and outside the heat-transfer area and heat-transfer area of heat-transfer matcrial thermal conductivity factor, the factors such as flow velocity of water.Past people is in order to improve boiler thermal output, or strengthens heat-transfer area or adopt the good material of thermal conductivity factor, or improves the flow velocity etc. of furnace temperature or water and gas, and its result often makes the volume of boiler increase, the cost rising.Moreover, owing to contain elements such as S, N in the fuel, produce SO through burning
2, NO
2Deng material, these materials can produce diluted acid when meeting with airborne moisture, the corrosion body of heater, thereby in design, often require its exhaust gas temperature can not be lower than 120 ℃; In addition,, in heating process, can produce incrustation scale and accumulate on the heat-exchange surface, may cause accidents such as booster like this, also necessarily require in design processing is softened in boiler feedwater for this reason if system's feed-water hardness is bigger.
The utility model content
The purpose of this utility model is prior art is improved, and a kind of novel structure, easy to operate, cost is low, the thermal efficiency is high fountain atmospheric hot-water boiler are provided thus.
It is such adopting technical solution for achieving the above object: be provided with water spray system in body of heater, circulation force (forcing) pump multi pack was on feed pipe in this spray equipment water inlet pipe end passed body of heater and passes through one, and the return pipe of spray equipment is connected to the combustion chamber water-cooling wall.The utility model changes the heat exchanging process of known water heater into gas (high-temperature flue gas that produces during burning) → liquid (hot water) exchange process by above improvement version, the interior water of stove is sent into water spray system by interior circulation force (forcing) pump during work, water droplet (mist) by the spray equipment ejection carries out sufficient heat exchange, heating furnace water with high temperature, the high speed flue gas that the combustion chamber produces.Owing to adopted the spray mode, increased the area of heat exchange in the stove greatly, the SO that produces during fuel combustion
2, NO
2Deng material in the dilution of a large amount of stove water with stove water in CaCO
3React Deng material, generate salt, so just greatly reduce the stove hardness of water.In addition,, the spray equipment return duct is had access to the combustion chamber of water-cooling wall, can reduce the temperature of outer wall of combustion chamber, prevent that hot gas from burning out the combustion chamber because furnace pressure is higher.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
The specific embodiment
Structure shown in Figure 1 is a kind of vertical water heater structure, this water heater by combustion chamber 4, the feed pipe 8 of the body of heater 3 that contains storage tank, burner 5, band water-cooling wall, form for water one-way valve 7, blow-off pipe 6, water spray system 2 and air preheater etc.By forming the internal circulation pump device for water one-way valve 7 and interior circulation force (forcing) pump 1, its effect is that the pressure that the hot water in the stove inner storing water case is forced into 0.1～1.2Mpa is offered spray equipment.The shower row net that water spray system is made up of 2～5 layers of (being illustrated as 3 layers) shower row 2, wherein orlop pipe row is made of the shower of at least one band top nozzle, all the other each layers constitute by the many parallel showers that are provided with, on every shower, be equipped with a plurality of nozzles down, after water is sent into spray equipment by the internal circulation pump pressurization in the stove, upwards spray discoid water column by following spray nozzle, last shower is a large amount of water droplet (mist) of ejection downwards, and abundant and flue gas carries out heat exchange.The return pipe 21 of spraying mechanism is connected to combustion chamber 4 water-cooling walls, and one can reduce the temperature of outer wall of combustion chamber, and second its flow control valve can be regulated the pressure of spray equipment.The drainage of this water heater is made up of blow-off pipe 6 and manual blowdown valve, by regular manual blowdown, improves the quality of stove water; If water heater produces a spot of incrustation scale because feed-water hardness is too high, these incrustation scales fall into stove inner storing water case because of accumulating on the heat-exchange surface, through drainage, also it can be discharged out of the furnace.Number in the figure 9 is an outlet pipe.
This atmospheric hot-water boiler simple in structure, volume is little, in light weight, price is low, thermal efficiency height, is convenient to maintenance, fixed its exhaust gas temperature of test is only high about 10 ℃ than stove coolant-temperature gage (80 ℃) factually, furnace thermal efficiency is not less than 92%.
Structure shown in Figure 2 is horizontal water heater structure, and shower row vertically arranges about being in this structure.
