Technical field
The utility model relates to a kind of boiler, and particularly the waterpipe type condensation heat homogeneous solution-type reactor of a kind of fuel oil, gas type belongs to the heating equipment field.
Background technology
Boiler is a kind of heating equipment, it is to utilize coal, oil or gas to be fuel, produce heat through burning and produce steam or hot water, flue gas, slag that coal produces pollute the environment, and the harm people's is healthy, and the processing of combustion technology and flue gas is comparatively complicated, oil gas type fuel is easy to carry and use, guaranteeing substantially not produce environmental pollution under the good burning condition, calorific capacity is high.In recent years, because the Methods of Oil-Gas Fired Boiler volume is little, automaticity is high, and is easy for installation, be widely used, and a large amount of primary energy of urban heat supplying boiler consumption, the pollutant of amplification quantity side by side, the heating boiler of China is mainly take fire coal as main traditionally.Raising along with the urban life level, in order to improve urban air-quality, use clean energy resource to become a kind of trend, in these years, our country finds and has exploited a large amount of natural gases, set up the heavy construction of transfering natural gas from the west to the east, some areas are (such as Beijing, Xi'an) be defined in the inaccurate coal heating boiler of setting up again in urban district, and recommendation natural gas boiler energetically, for fear of the back-end surfaces cold end corrosion, traditional coal heating exhaust gas temperature is usually above 150 ℃, steam boiler even be higher than 200 ℃ adopts after the natural gas, and most hot-water boiler exhaust gas temperature is between 140～200 ℃, this has not only expended a large amount of energy, and having improved the operating cost of boiler, the boiler take natural gas as fuel, the flue gas of discharging have 150 ~ 250 ℃ of quite high temperature, it contains the about 15% ~ 19%(volume of steam), be the main carrier of flue gas heat.If the exhaust gas temperature of boiler is dropped to enough low level, the steam that is so superheat state in the flue gas will condense and emit the latent heat of vaporization, the boiler that the latent heat of vaporization in the flue gas is recycled is called condenser boiler, there are the defectives such as efficient is low, equipment is perishable, the untimely convenience of UTILIZATION OF VESIDUAL HEAT IN in traditional flue heat exchange design, cause boiler to use the decline of whole efficiency, wasted a large amount of energy.
Summary of the invention
The utility model is for providing a kind of waterpipe type condensation heat homogeneous solution-type reactor that can comparatively abundant and conveniently utilize timely flue residue heat, permanent economy and durability.
Waterpipe type condensation heat homogeneous solution-type reactor provided by the utility model, comprise body of heater, flue, in flue, be provided with two-stage heat-exchanger rig energy-saving appliance and condenser, the energy-saving appliance entry links by No. 1 header tank and boiler blow-down water, water outlet links by No. 2 header tanks and boiler feedwater, backwater and flue gas are adverse current, the condenser entry links by No. 3 header tanks and boiler blow-down water, water outlet links by No. 4 header tanks and boiler feedwater, backwater and flue gas are the adverse current state, and described condenser is comprised of high frequency welded fin-tube, and material adopts the ND steel, described condenser (4) heat exchanger tube adopts steel-aluminum composite fin tube, and housing adopts enamel anticorrosion.
Waterpipe type condensation heat homogeneous solution-type reactor provided by the utility model, be provided with energy-saving appliance and condenser in the flue, can utilize preferably flue residue heat, reduce exhaust gas temperature, energy-saving appliance and condenser adopt special process and material, the environmental corrosion of anti-the flue gas, durable in use, energy-saving appliance and condenser Water Exit directly and boiler feed water and backwater link, utilized timely and conveniently the heat exchange energy, had significant energy-saving effect, another effect of flue gas condensing is the discharging that can reduce NOx, this is on the one hand because the raising of the condenser boiler thermal efficiency, reduced the consumption of fuel, reduced total release, on the other hand owing to the absorption of condensate liquid to NOx, further reduced again discharging, can find out to the utlity model has good economy and environment benefit.
Description of drawings
Accompanying drawing 1 is schematic diagram of the present utility model.
Accompanying drawing 2 is working medium flow schematic diagrames of the present utility model.
The specific embodiment
In order to explain more fully enforcement of the present utility model, specific embodiment of the utility model is provided, present embodiment only is to elaboration of the present utility model and explanation, does not limit scope of the present utility model.
As shown in drawings, energy-saving appliance 3 and condenser 4 are set in boiler flue, this boiler can be two drums and vertically arranges, full fin panel casing, D type burner hearth Natural Circulation, the hot-water boiler of pressurized firing, the front wall collocation burner, after fuel fully burns in burner hearth, turn back 90 ° and enter convection bank, flue gas flows into energy-saving appliance 3 from convection bank through flue, condenser 4, then entering chimney discharges, burner hearth Hou Qiang has arranged explosion proof door in the position, energy-saving appliance 3 is comprised of gilled tube, gilled tube is that high-frequency welding processes, shell side one end of energy-saving appliance 3 links to each other with convection heating surface, the other end links to each other with the shell side of condenser, condenser 4 is used for further reducing exhaust gas temperature, and the latent heat of vaporization of steam in the absorption tail flue gas, the heating surface of condenser mainly is comprised of high frequency welded fin-tube, material is the ND steel, the ND steel is present domestic and international rotten steel of using of the most desirable dew point of anti-the sulfuric acid low temperature, has good acid corrosion-resistant for the manufacture of the heat exchanger of in high sulfur-containing smoke gas, being on active service and evaporimeter, the anti-chlorine ion corrosion performance, condenser heat-exchange pipes adopts high frequency welded fin-tube, housing adopts enamel anticorrosion, gilled tube in energy-saving appliance 3 and the condenser 4 is listed as or is staggered in arrangement for suitable, energy-saving appliance 3 and condenser 4 be interior to be provided with 4 header tanks altogether, heat exchange element is steel-aluminum composite fin tube, steel-aluminum composite fin tube links to each other with header tank, boiler blow-down water is before entering condenser, split into two parts, a part enters header tank 7 No. 2, another part enters header tank 5 No. 4, then enters respectively energy-saving appliance 3 and condenser 4, is pooled to respectively after the heat exchange No. 1 and No. 3 header tanks, compile and then enter boiler feedwater, backwater and flue gas are the adverse current state.
