Abstract

The utility model relates to a gas burning and heating melting furnace for melting the solid asphalt. The utility model is composed of a pot, a pot cover, a combustion chamber, a flue, an oil discharging tube, etc. A bending-shaped flue is arranged in the pot. The combustion chamber is arranged at one end of the pot. One end of a smoke sucking pipe is arranged in the combustion chamber. The other end of the smoke sucking pipe is arranged in the pot and is higher than the asphalt liquid surface in the pot. The side wall of the other end of the pot is provided with an electrothermal temperature controller, and the lower end of the side wall is provided with the oil discharging tube. The utility model has the advantages of simple structure, convenient use, rapid temperature rise, obvious purifying effect and obvious power saving value. Thereby, the gas burning and heating melting furnace is an ideal heating melting furnace for melting the solid asphalt.

Description

Smoke removing asphalt gas burning and heating melting furnace

The utility model belongs to a kind of heating furnace, especially for the gas furnace of melting solid pitch.

At present, general melting solid pitch is in our a mouthful cauldron, burns under pot with coal or firewood, not only efficient is low, and power consumption is big, and coal smoke and bitumen flue gas directly enter atmosphere, contain a large amount of carcinogens in the exhaust thing, serious environment pollution influences health.The patent No. is that the 86206320 smoke elimination asphalt melting stoves and the patent No. are 892000503 vertical injection smoke elimination asphalt heating pot, though the pollution when having prevented molten asphalt, purification efficiency is still not very good, owing to all need heat with coal, thereby also more complicated of structure.

The purpose of this utility model is a kind of a kind of not only saving of labor who utilizes that coal gas heats of design, save time, energy-conservation, efficiently but also safe ready and clarifying smoke efficient is reached more than 98%, the glance coal purifying rate reaches the smoke elimination pitch combustion gas heat fused stove simple in structure more than 99%.

The utility model concrete structure and embodiment, the contrast description of drawings is as follows:

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 1-combustion chamber, 2-Smoking pipe, 3-pot body, the 4-pot cover, 5-bending flue, 6-flue, 7-electroheat pair temperature controller, 8-drain line, the 9-mouth of draining the oil, the 10-support, 11-coal gas burner, 12-air inlet, the 13-air inlet, 14-weigh tank, the 15-weigh tank mouth of draining the oil, the 16-platform.

The utility model is by pot body 3, pot cover 4, combustion chamber 1, parts such as flue 6 and drain line 8 are formed, pot body 3 tops are provided with pot cover 4 and flue 6, end in the pot body 3 is provided with combustion chamber 1, be provided with bending flue 5 in the pot body 3, bending flue 5 is a S shape, one end of bending flue 5 communicates with the flue 6 at pot body 3 tops, the other end communicates with combustion chamber 1, be provided with a Smoking pipe 2 on 1 madial wall of combustion chamber, an end that makes Smoking pipe 2 is in pot body 3, and the other end is in the combustion chamber, on the sidewall of the other end of pot body 3, be provided with electroheat pair temperature controller 7, side wall lower ends is provided with drain line 8, and drain line 8 is provided with the mouth 9 of draining the oil, and the end of pot body 3 is equipped with metallic support 10.

The purpose of this utility model is achieved in that this utility model is placed on one to be had on the platform 16 of certain altitude, solid asphalt packed into make pitch be lower than Smoking pipe 2 in pot body 3 to cover pot cover 4 completely, light coal gas burner 11, combustion chamber 1 is in the duty, solid asphalt is melted and produces glance coal and enter by the Smoking pipe 2 that is higher than the pitch liquid level and make a large amount of combustibles contained in the glance coal through burning once more in the combustion chamber 1, reduce exhaust emission, save the energy, gas fire in the combustion chamber 1 enters flue 6 by bending flue 5, makes full use of heat.When the asphalt temperature in the pot body 3 is heated to 180～220 ℃ (can learn) from electroheat pair temperature controller 7, the size of control coal gas burner flame, after pitch boils, open mouth 9 pitches of draining the oil and just automatically flow into quantitatively in the bucket 14, pro rata other raw material with manufacturing pitch brick mixes and makes the fire-resistant pitch brick of using in the converter.

The utility model is simple in structure, quick heating, clean-up effect and energy-conservation value are obvious, and after tested, it reaches 996% to the glance coal purification efficiency.Concentration of emission can reach 81mg/m ³Purification efficiency to flue dust reaches more than 98%, and concentration of emission can reach 2mg/m ³Meet the smoke abatement and dust control of stipulating in the GB8841-83II class and administer every index performance of environmental aspect, be better than building the road and build a house with WS-2 type asphalt heating kettle, improve work efficiency 4-5 doubly, and safe and reliable, easy to use is steel mill desirable heat fused stove of melting solid pitch when making the fire-resistant pitch brick of using in the converter.
