Abstract
A rotary roasting kiln adopting a lignite gasification furnace for heating comprises a rotary drum (1), a support transmission device (2), a tunnel kiln (3) covering the rotary drum (1) and a heating device arranged in the tunnel kiln (3) and located below the rotary drum (1). According to the rotary roasting kiln, the heating device (4) adopts the lignite gasification furnace, that is, gas produced by the lignite gasification furnace is connected with branch pipelines (6) through a main pipeline (5) respectively, a plurality of sub-pipelines (7) are arranged and distributed in a circular arc shape by corresponding to the heating surface of the abdominal part of the rotary drum (1), and flame nozzles (8) on the branch pipelines (7) spit fire to heat the rotary drum. The rotary roasting kiln has the benefits as follows: the temperature of flame formed by lignite gas is very high and can be higher than 1,000 DEG C; the flame formation temperature can be adjusted by adjusting the flame nozzles, and the heating effect is very good; and the cost of lignite is very low and is about 0.52 yuan/kg, the burning cost is one fourth of the cost of electric heating, and the rotary roasting kiln has the remarkable advantages of energy saving and capability of improving the efficiency.
Description
Technical field
The utility model belongs to a kind of external-heating rotary kiln of dynamic roasting, especially de-organic external-heating rotary kiln structure, particularly heater technical field of structures of calcined catalyst decarburization.
Background technology
The external-heating rotary kiln of existing dynamic roasting, especially calcined catalyst decarburization take off organic external-heating rotary kiln structure, and its working speed is 0.42r/min, frequency control within the scope of 0.1～0.8 r/min; Material time of staying in whole cylinder is 220 minutes, and wherein in heating furnace burner hearth, the time of staying is 150 minutes.Substantially be all to adopt electrical heating, in tunnel cave, be positioned at revolving cylinder below adopt electric furnace heating wire or Elema to heat.Due to the temperature of charge in cylinder up to 600 ℃～650 ℃, so cylinder external heat temperature at least possesses 800 ℃, at present, the heating power of this rotary kiln preparation is more than 270kw, but heating technique weak effect, power consumption is but very large.
Summary of the invention
The purpose of this utility model just for wasting energy of overcoming that above-mentioned prior art exists, heat and be difficult to meet the defect of specification requirement and not enough and a kind of calcination rotary kiln that relies on brown coal gasifier heating is provided.
The utility model is achieved by the following technical solution.
A brown coal gasifier heating calcination rotary kiln, comprise revolving cylinder, support transmission device, be located at revolving cylinder outside tunnel cave, be arranged in tunnel cave and be positioned at the heater of revolving cylinder below; The utility model heater adopts brown coal gasifier, the coal gas that is about to brown coal gasifier generation connects respectively subtube by main pipeline, adopt again some branch pipe(tube)s to distribute and be set to circular arc according to the heating surface to revolving cylinder belly, by the bocca flame on branch pipe(tube), form revolving cylinder is heated.
The beneficial effects of the utility model are, the flame temperature that brown coal gas forms is high, can reach more than 1000 ℃, and by regulating bocca, the temperature that adjustable flame forms, heating effect is splendid.Because the cost of brown coal is extremely low, approximately 0.52 yuan/kg, its burning cost is electrically heated 1/4th, has the remarkable advantage of saving the energy, raising the efficiency.
Below in conjunction with drawings and Examples, further illustrate the utility model content.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional structure schematic diagram of the A-A of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2, a kind of brown coal gasifier heating calcination rotary kiln, comprise revolving cylinder 1, support transmission device 2, be located at revolving cylinder 1 outside tunnel cave 3, be arranged in tunnel cave 3 and be positioned at the heater 4 of revolving cylinder 1 below; The utility model heater 4 adopts brown coal gasifier, the coal gas that is about to brown coal gasifier generation connects respectively subtube 6 by main pipeline 5, adopt again some branch pipe(tube)s 7 to distribute and be set to circular arc according to the heating surface to revolving cylinder 1 belly, by bocca 8 flames on branch pipe(tube) 7, form revolving cylinder is heated.
Claims (1)
