Abstract
The invention discloses a novel combustion furnace for preparing carbon black. The novel combustion furnace comprises a combustion chamber, a throat pipe and a reaction zone, wherein high chromium corundum bricks are arranged inside the combustion chamber, the throat pipe and the reaction zone. Compared with the prior art, the blackness and the yield of the carbon black can be effectively improved, the service life of the combustion furnace is prolonged, and the work efficiency of the combustion furnace for preparing the carbon black is greatly improved.
Description
Technical field
The present invention relates to carbon black preparation field, particularly relate to a kind of novel carbon black and prepare roasting kiln.
Background technology
Carbon black is generally to form by coal tar, carbolineum, heavy oil, Sweet natural gas etc. are carried out to incomplete combustion in certain particular device, using maximum particular devices is at present roasting kiln, and the effect of roasting kiln in the whole technical process of preparing carbon black seems particularly important.What nowadays general carbon black preparation was selected with the refractory materials of roasting kiln inside is chrome corundum brick, can tolerate the temperature of 1500 ℃ of left and right, although can make carbon black products, but restricted application, and the furnace temperature of roasting kiln is to affect an important factor of carbon black reaction, therefore limit productive rate and the blackness of carbon black, some special dimension, when blackness to carbon black products and productive rate requirement are higher, this roasting kiln just cannot meet the demands.
Summary of the invention
Technical problem to be solved by this invention, is exactly for above-mentioned the deficiencies in the prior art, and the novel carbon black that provides a kind of and can tolerate higher temperature, improves carbon black blackness and productive rate is prepared roasting kiln.
To achieve these goals, technical scheme of the present invention is as follows:
Novel carbon black is prepared a roasting kiln, comprises combustion chamber, trunnion and conversion zone, and the inside of described combustion chamber, trunnion and conversion zone is provided with high chrome corundum brick interlayer.
The invention has the beneficial effects as follows: used high chrome corundum brick by the roasting kiln inwall of preparing at carbon black, significantly improve carbon black and prepared the tolerable temperature of roasting kiln, can reach 1700 ℃ ~ 2000 ℃, extended roasting kiln work-ing life, and the blackness of carbon black products and productive rate also have largely and have improved.
Accompanying drawing explanation
Accompanying drawing is specific embodiment of the invention sectional view;
In figure: 1 – combustion chamber; 2 – trunnions; 3 – conversion zones; 4 – oil combustion guns; The former oil gun of 5 –; The high chrome corundum brick of 6 –.
Embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, the specific embodiment of the invention is carried out to clear, complete description.
As shown in drawings, a kind of novel carbon black is prepared roasting kiln, comprises combustion chamber 1, trunnion 2 and conversion zone 3, and the inside of described combustion chamber 1, trunnion 2 and conversion zone 3 is provided with high chrome corundum brick 6.Be provided with oil combustion gun 4 in the ingress of combustion chamber, be provided with crude oil at the side of trunnion 2 and rob 5.Principle of work is: fuel is pushed combustion chamber by oil combustion gun 4, afterwards with air combustion produce high temperature, crude oil rob 5 by stock oil send into combustion chamber at high temperature cracking obtain carbon black.This carbon black preparation burning furnace temperature can reach 1700 ℃ ~ 2000 ℃, and has significantly improved the blackness of carbon black products, and product yield also increases to 300Kg/h.
The above is preferred embodiment of the present invention; the technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in scope of patent protection of the present invention.
