Condenser 9 pipelines are in line, at first with accomplishing the first heat exchange backhaul in the condenser pipe 12 of high-temperature flue gas on the circular back of horizontal boiler; In the condenser pipe 12 on the both sides that are embedded in horizontal boiler, accomplish second backhaul again, this kind design belongs to back of the body wet type.The design of condenser pipe 12 is then calculated according to the exhaust air rate and the heat exchange area of boiler; All can be from several tons to tens tons horizontal boilers by this principle design; The condenser pipe 12 at boiler top can be designed to many rows; The condenser pipe 12 of boiler both sides also can be designed to many rows, and this kind design is applicable to the hot-water boiler of big or small various tonnages; The sulfuration bed, or coal burning boiler is filled out in mechanization automatically.
Show among the figure that dirt pocket 10 is in the body of heater at the rear portion of Heat Room 7, the desulfurization pond 13 of height 500mm is arranged at dirt pocket 10 bottoms, and desulfurization pond 13 can extend to the bottom of Heat Room 7.The desulfurization water that the limy stone flour is arranged in the desulfurization pond 13 is installed high-pressure pump 14 in the desulfurization pond 13, there is nozzle 15 dirt pocket 10 tops, and nozzle 15 is connected with high-pressure pump 14 through jet pipe 16.With high-pressure pump 14 desulfurization water is pressurizeed; Carry out desulfurization with 15 pairs of high-temperature flue gas of spiral nozzle; This moment, the dust granule in the high-temperature flue gas was caught by water smoke and desulfurization water falls into design together in the desulfurization pond 13 of boiler bottom, and the sulfide in the flue gas is by the buck desulfurization simultaneously.After high-temperature flue gas behind the desulfurization and dedusting and the collision of desulfurization water, can form steam, steam is under the gravitation of air-introduced machine; Get in the condenser pipe 12 at boiler top; Through a backhaul, return again and get in the boiler both sides condenser pipe 12, the bottom flue is discharged and is got into chimney 8 behind the boiler.Because 12 designs of lower floor's condenser pipe are in boiler both sides water jacket 11, and at boiler bottom, water temperature is lower than 50 °, in this backhaul, steam is through the condensing heat-exchange of two backhauls, and steam becomes condensed water, is discharged from outside the body of heater 1.
Show among the figure; The present invention has installed chimney heat exchanger 20 in boiler rear wall bottom, and flue gas is discharged at boiler bottom water temperature lowest part, and design chimney heat exchanger 20 is in order to adapt to the heating standard of 60 ° of 80 ° of return water temperatures of China's boiler heating hot water outlet temperature; Because this standard return water temperature is higher than 50 °; Can not form dew-point temperature, fully condensing heat-exchange influences the heat exchange effect.In order residual temperature wherein all to be absorbed in the flue gas rearmost end, in the area that heating temperature adopts above-mentioned standard, design and installation chimney heat exchanger 20.Chimney heat exchanger 20 still adopts the comb design, is the boiler air inlet in the pipe, and the pipe side is the boiler exhaust outlet.This kind design belongs to the air heat exchange.Utilize condensation to cross the oxygen before the surplus temperature heating of flue gas gets into burner hearth.Increase the oxygen temperature in the burner hearth, can increase fire box temperature, make coal-fired fully burning, reduced exhaust gas temperature simultaneously.Can realize that maximal efficiency utilizes the energy.The exhaust gas temperature that test boiler this moment is that 30/50 ° of thermal efficiency can reach 80%/95%.
Show among the figure that condenser pipe 12 is a spiral grooved tube, spiral grooved tube is a prior art, but never on condenser pipe 12, adopts spiral grooved tube, and it is a quantum leap technically that the present invention adopts spiral grooved tube.
Air in the spiral grooved tube and the outer hot water of pipe all receive the spiral fluted disturbance, are that fluid main flow rapids district mobility strengthens on the one hand, on the other hand attenuate the negative bed thickness of keeping on file layer by layer thermal resistance is reduced, the result of both effects has all strengthened the heat transfer inside and outside the pipe.The spiral grooved tube heat transfer property is also relevant with the helicla flute lift angle with spiral fluted pitch t, groove depth h, and relative parameter h/t heat transfer coefficient when 0.05-0.075 is better, especially with best near the h/t=0.06.The heat-transfer effect of spiral grooved tube improves about 52% than light pipe, wall temperature increases about 22.4 ° than light pipe.Spiral grooved tube also has anti-dust stratification ability, when flue gas flows at the helicla flute of tube wall, advances with spiral status, has so both increased flue gas and has rotatablely moved, and has strengthened the disturbance to tube wall simultaneously, makes the flying dust of carrying under one's arms in the flue gas be difficult for silence and gets off.
Show among the figure; Lime powder box 17 is installed on the boiler rear wall; Funnel is arranged at lime powder box 17 bottoms; The funnel lower pipeline is connected with desulfurization pond 13, and the pulverized limestone rotor is arranged at the funnel bottom, and the current rotor of the supply channel in the desulfurization pond 13 of pulverized limestone rotor and dirt pocket 10 is fixed on same horizontal rotating shaft.When supply channel supplied water, current promoted the current rotor rotation, drive the pulverized limestone rotor rotation simultaneously, and the pulverized limestone of funnel bottom is pushed in the desulfurization pond 13, formed and added running water and pulverized limestone automatically.The dosage of running water and the addition of pulverized limestone are directly proportional, and the concentration of desulfurization pond 13 sodalime powder according to measuring the chemical content of discharging flue gas, is carried out proportioning.
Show among the figure; Feed cistern 18 is installed on the boiler rear wall, and feed cistern 18 has supply channel to be connected with the desulfurization pond 13 of dirt pocket 10, in feed cistern 17, has water to float opening device; Water floats opening device when the height that the liquid level gauge of water level decline is set, and opens water supply valve and supplies water.
Show among the figure that the bottom in desulfurization pond 13 is a ramp type, the bottommost on the slope has electronic sewage draining valve 19, and electronic sewage draining valve 19 is connected with the time relay, utilizes the time relay to control electronic sewage draining valve 19.According to the concentration of boiler desulfurization dedusting water, formulate blowing time, carry out automatic pollution discharge.
The present invention makes things convenient for desulfurization, dedusting because flue gas passes through in condenser pipe 12, or else from then on boiler install deduster with other, can practice thrift the material, equipment, the electric power that are used to make deduster equipment in a large number.
