Abstract

The utility model relates to an environment-protecting no-smoke energy-saving steam boiler, which comprises a furnace body, a pedestal, a slag-cleaning door, a drainage port, a water inlet, an inner container, a smoke outlet, a safety valve, a pressure meter, a water level gauge, a coal filling port and an ignition port. The utility model is characterized in that: a step-type circulating water pipe grate is communicated with the inner container; a movable grate that supports secondary combustion is arranged under the circulating water pipe grate; an inclined water-running fast-heating pipe which is communicated with the inner container is respectively arranged in and out of the combustion room formed by the circulating water pipe grate; a heat pipe which is communicated with the inner container is arranged at the two sides of the upper part of the furnace body along the vertical direction; an inclined heat pipe which is communicated with the inner container is arranged in the middle thereof; a re-heating steam pipe is arranged on the top of the inner container and through the smoke outlet pipe; the smoke outlet is provided with a semi-circular smoke flashboard. The utility model has the advantages of ventilation, smooth fire-running, easy slag-cleaning, high thermal efficiency and full combustion without producing smoke and dust.

Description

Environmental protection non-smoke and-dust energy-saving steam boiler

Technical field:

The utility model belongs to the boiler technical field of heating, in particular a kind of environmental protection non-smoke and-dust energy-saving steam boiler.

Background technology:

At present, the fire grate in the normal pressure back firing boiler commonly used all is the plain grate that laterally cocks off, and has smooth, the obturation of cocking off of ventilating, scarfing cinder difficulty, thin excessively, the inadequate shortcoming of burning of burning zone, and the untimely coal of filling out just may stop working.In addition, the set-up mode of heat pipe is single, and the resistance to cigarette vapour of horizontally set is big, and it is slow to walk cigarette, and vertically the smoke evacuation that is provided with is too fast, reduces the absorption of heat, and the thermal efficiency is low.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of ventilation, it is smooth and easy to cock off, scarfing cinder is easy, the thermal efficiency is high, the environmental protection non-smoke and-dust energy-saving steam boiler with step circulating water pipe fast heating furnace row of sufficient combustion.

The technical solution of the utility model is achieved in that it comprises body of heater, base, deashing slag door, sewage draining exit, water inlet, inner bag, exhaust opening, safety valve, Pressure gauge, the water level meter, coal feeding hole, lighting-up tuyere, be communicated with inner bag and be provided with step circulating water pipe fire grate, be provided with moving grate below the circulating water pipe fire grate for second-time burning, in the combustion chamber that the circulating water pipe fire grate forms, be respectively equipped with the tilting that is communicated with the inner bag quick heating pipe of leaking water outward, body of heater internal upper part both sides vertical direction is provided with the heat pipe that is communicated with inner bag, the middle connection with inner bag is provided with the tilting heat pipe, pass pipe and inner bag top and be provided with heating steam pipe again, exhaust opening is provided with semicircle cigarette plate.

Good effect of the present utility model is: owing to adopt step circulating water pipe fire grate, the combustion chamber ventilates, cocks off smooth and easy, the disposable coal of filling out can burn 3-4 hour, what terraced grate fell can coal-fired can burn on moving grate once more, effectively utilize the energy, reach purpose of energy saving, thermal efficiency height; At the coal feeding hole funnel draught, the flue dust that coal combustion forms is walked in fire, is converted into heat energy, not only reaches the smokeless effect of environmental protection, and makes full use of heat energy.Heat pipe in conjunction with being provided with, can reduce the resistance to flue gas anyhow, does not make fume emission too fast again, and the courage inner structure fully is heated, and improves the thermal efficiency; Pass pipe and inner bag top and be provided with heating steam pipe again, utilize waste heat to heat again, make outlet steam heat not supercharging, water temperature reaches 95-100 ℃, and steam can reach more than 150 ℃, effectively utilizes heat energy; Exhaust opening is provided with semicircle cigarette plate, can regulate fume emission speed.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

With reference to Fig. 1, the utility model comprises body of heater 8, base 23, deashing slag door 1, sewage draining exit 2, water inlet 21, inner bag 7, exhaust opening 10, safety valve 12, Pressure gauge 13, water level meter 14, coal feeding hole 17, lighting-up tuyere 20, the 3rd, put grey plate, the 4th, breast hole, the 5th, the top shoot door is communicated with inner bag 7 and is provided with step circulating water pipe fire grate 16, the clear and coherent row's fire of each step fire bed, promote mutually, it is combustion-supporting mutually to combine, and fuel is thoroughly burnt and is converted into heat energy; Be provided with the moving grate 22 for second-time burning below the circulating water pipe fire grate, make flammable cinder all burn into lime, fall from moving grate, all water pipe furnace grates become quick heating pipe entirely, directly are heated, and adopt the refractory material sealing between the coal bunker upper tube; In the combustion chamber that the circulating water pipe fire grate forms two quick heating pipes 18 of leaking water are arranged, solved that the coal seam is thick, the fire bed pressurized is crossed little, the resistant problem of ventilating of cocking off of dead spacing; Be provided with the tilting that is communicated with the inner bag quick heating pipe 19 of leaking water outside the combustion chamber, body of heater internal upper part both sides vertical direction is provided with the heat pipe 6 that is communicated with inner bag, the middle connection with inner bag is provided with tilting heat pipe 15, anyhow in conjunction with being provided with, can reduce resistance to flue gas, do not make fume emission too fast again, the courage inner structure fully is heated, improve the thermal efficiency; Pass pipe and inner bag top and be provided with heating steam pipe 9 again, utilize waste heat to heat again; Exhaust opening is provided with semicircle cigarette plate 11, can regulate fume emission speed.

The utility model does not need air blast, air-introduced machine and cleaner, the power saving of economizing on coal, aspect such as be applicable to bathing, boiling, oven dry, hot pressing, brewage.
