Abstract
The utility model provides a kind of and produces the method and the device thereof of steam with indirect heating type boiler, and solving indirect heating type boiler can only be with the water heat temperature raising in the coil pipe, and can not produce steam for producing and the problem of life use.The utility model is provided with heat exchanger coils in the boiler main frame, the sender property outlet of coil pipe is connected with the top of evaporimeter, and the working medium inlet is connected with the hydrospace, bottom of evaporimeter by circulating line.At first,, send into flash-boiling evaporators and produce steam then with the working-medium water after the heating in the coil pipe by the working-medium water in the intermediate medium heating heat exchanger coil pipe in the indirect heating type boiler pot.According to the utility model, utilize indirect heater, can continuously produce a large amount of steam, safety, economic, reliable.
Description
Technical field
The utility model relates to firing equipment, especially a kind of indirect heating type steam boiler.
Background technology
Present steam boiler all is that water is directly delivered in the boiler, is heated to be vaporizated into steam in pot.Owing to contain the calcium ion and the magnesium ion of thoroughly Ex-all in the water, on boiler heating surface, will tie unavoidably and scale, for reducing since the harm of problems such as overheated, the bulge that incrustation scale causes boiler, booster, crackle, burn into waste fuel to expend the person property water is softened processing.In addition, for the oxygen that dissolves in the anti-sealing etc. causes corrosion to boiler, also need to expend the person property and deoxygenation is carried out in boiler feedwater handled.
Use intermediate medium in the pot of indirect heating type boiler, the working-medium water that needs heating does not contact with boiler heating surface in heat exchanger coils, therefore, problems such as above-mentioned scaling and oxygen corrosion can not take place in the pot of indirect heating type boiler.But indirect heating type boiler in the past can only use and can not produce steam the water heat temperature raising in the coil pipe for production and life.
Summary of the invention
The purpose of this utility model provides a kind of indirect heating type steam boiler, solving indirect heating type boiler can only be with the water heat temperature raising in the coil pipe, and can not produce steam for the problem of producing and life is used, utilized the advantage of indirect heating type boiler, simultaneously, security, economy, the reliability of boiler have been improved.
The technical solution of the utility model is: a kind of indirect heating type steam boiler, be provided with heat exchanger coils in the boiler main frame, the sender property outlet of coil pipe is connected with the top of evaporimeter, the working medium inlet of coil pipe is connected with the bottom of evaporimeter by circulating line, and steam (vapor) outlet is communicated with the top vapor space of evaporimeter.
On the working medium of the coil pipe inlet circulating line, but series circulation pump also.
Above-mentioned indirect heating type steam boiler, evaporimeter is a vertical type evaporator, and perpendicular in the evaporimeter have a mid-dividing plate, and the two ends of mid-dividing plate are connected with evaporator shell, leave steam-water channel up and down; The inlet of coil pipe working medium inlet circulating line or circulating pump and the outlet of evaporimeter make-up pipe are positioned at the both sides of mid-dividing plate; The sender property outlet pipe of coil pipe connects the water distribution floral tube in the evaporimeter.
According to the utility model, the working-medium water of elevated pressures enters the indirect heating type boiler heat exchanger coils, after being heated to higher temperature, introduce flash-boiling evaporators, temperature is higher than the water of vapourizing temperature under the evaporator pressure, after entering evaporimeter, because the reduction of pressure, the part flash-off of steam uses for productive life, part is present in the evaporimeter bottom, is recycled pipeline or circulating pump and delivers to the boiler heat-exchanger coil pipe and heat once more, and so circulation repeatedly, constantly supplement boiler feedwater just can constantly produce steam simultaneously.
Because working-medium water do not contact boiler heating surface, problems such as above-mentioned scaling and oxygen corrosion take place with regard to not causing in calcium ions and magnesium ions in the working-medium water and dissolved oxygen at boiler heating surface.
In addition, because the carbonate deposit composition in the water just can separated out below 100 ℃ substantially fully, the noncarbonate composition of scale just can be separated out when evaporation and concentration, therefore, in make-up water is mended evaporimeter and be heated to when entering heat exchanger coils again about 100 ℃, carbonate deposit composition in the water is just separated out, and has stayed in the evaporimeter; Water about 100 ℃ enters and flows to when vaporizing in the evaporimeter after heat exchanger coils is heated once more again, noncarbonate composition of scale in the water is just separated out because of evaporation of water concentrates, also stayed in the evaporimeter, so, incrusted degree reduces greatly in the heat exchanger coils, not even fouling, the safety of boiler, economy, reliability improve greatly, save a large amount of water treatment expenses.
Description of drawings
Fig. 1, Fig. 2 are structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, Fig. 2 is the concrete enforcement structure chart of Fig. 1.Indirect heating type steam boiler shown in Figure 2, boiler main frame 1 is the organic media phase change vacuum boiler, be provided with heat exchanger coils 2 in the boiler main frame, the sender property outlet 3 of coil pipe is connected with the top of vertical type evaporator 4, the working medium inlet 5 of coil pipe is connected with the bottom of evaporimeter by circulating line 6 and water circulating pump 8, steam (vapor) outlet 7 is communicated with the top vapor space of evaporimeter, erect in the evaporimeter mid-dividing plate 9 is arranged, the inlet 10 of water circulating pump water inlet pipe and the outlet 12 of evaporimeter make-up pipe 11 are positioned at the both sides of mid-dividing plate, and highly big about half high position of evaporimeter, the sender property outlet pipe of coil pipe connects the water distribution floral tube 13 in the evaporimeter.Evaporimeter is provided with necessary annexes such as water level meter, Pressure gauge, safety valve, blowoff valve, and the organic media phase change vacuum boiler is provided with necessary annexes such as pressure vacuum gauge, liquid level gauge, vacuum pressure controller.Mid-dividing plate and the inlet of circulating pump water inlet pipe and the effect of make-up water mouth of pipe position in the evaporimeter, be to prolong the time of staying of feedwater in evaporimeter, feedwater is entered can be warmed up to behind the evaporimeter to surpass about 100 ℃ and enter heat exchanger coils again, make in the water carbonate deposit fully separate out and settlement in evaporimeter; A lot of apertures are arranged on the water distribution floral tube, its role is to reduce disturbance, evenly evaporation, the noncarbonate incrustation scale settlement of separating out when making evaporation and concentration.This embodiment has not incrusted substantially characteristics in the coil pipe.
During work, after the low temperature make-up water enters evaporimeter, with top saturation water Hybrid Heating after be higher than about 100 ℃, be recycled pump and pump into phase change vacuum boiler coil pipe inlet, saturation temperature under boiler is heated to above evaporator operation pressure, but will continue to keep liquid under pressure, enter the evaporimeter decompression evaporation by the water distribution floral tube then, part water becomes that saturated vapor rises to air space and discharges through steam (vapor) outlet and uses for productive life, another part water flows downward, pump into the boiler coil pipe and heated once more with being recycled pump after the make-up water of mend mixes, so circulate repeatedly, constantly produce saturated vapor.When the make-up water mass flow was identical with the steam raising mass flow, the evaporimeter water level remained unchanged.
