Abstract
The utility model discloses a hot air pipeline for carbon black production equipment by an oil furnace method. The pipeline comprises a carbon steel pipe, as well as an insulating layer of an aluminum oxide hollow sphere on the inner wall of the carbon steel pipe and a flame retardant layer built by white corundum bricks on the inner wall of the insulating layer. By adopting the utility model, the investment is small, the insulating property is good, the heat loss is small, the preheated air temperature reaches 650 to 850 DEG C, and the lost heat is only at about 1 percent through the hot air pipeline, so that the energy is saved, the yield and quality of the carbon black are improved, the maintenance cost is low, the service life is long, and the thermal shock resistance is strong.
Description
Technical field
The utility model relates to a kind of pipeline of conveyance fluid medium, especially a kind of hot air duct that is used for oil oven method production of carbon black equipment of carrying hot air.
Background technique
In the modern oil oven method manufacturing technologies of carbon black, black reactor is by flue directly in succession heat exchanger-air preheater and oil preheater.Make the reaction furnace of carbon black discharge the flue gas cooling on the one hand, utilize used heat preheated air and oil on the other hand, with the fuel saving oil consumption so that carrying out carbon black collects.Wherein, carbon black reacts the height of the UTILIZATION OF VESIDUAL HEAT IN, particularly air preheating temperature of flue gas, can reveal the cleaner production level of carbon black production device using energy source from a side surface body.Along with carbon black production technology constantly develops, to the desired temperature of combustion air also more and more higher (about 650 ℃～900 ℃), acquisition plays huge effect near the air preheating temperature of the upper limit to carbon black mass and economic benefit as far as possible.
The material in hot air delivery pipe road is metal material such as 310S stainless steel traditionally.The 310S stainless steel is the Austenitic stainless steel, has good oxidative stability, corrosion resistance, at high temperature can continuous operation, be widely used in the hot-air duct aspect.Yet, in investment, account for very big share because abros is expensive especially; And, find through production practices for many years, be that the hot air duct of material has phenomenons such as cracking, embrittlement with the 310S stainless steel after using several years.Because the stainless nickel of 310S, chromium content height, after above-mentioned phenomenon took place pipeline, its repair by welding is unusual difficulty also, even after the welding, working life is president not also, and it is very big unfavorable that this has just caused to the production of carbon black.
The model utility content
The technical problems to be solved in the utility model provides a kind of hot air duct that is used for oil oven method production of carbon black equipment of cheap, durable and high insulating effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is to comprise carbon steel tube, the brick refractory layer of building of white fused alumina that also comprises the thermal insulation layer of the alumina hollow ball of being located at the carbon steel tube inwall and be located at described thermal insulation layer inwall.
In the technique scheme, the refractory layer that adopts white fused alumina to build by laying bricks or stones is done liner, can be high temperature resistant, and can resist the rapid change of temperature and be not destroyed; The thermal insulation layer of alumina hollow ball is as novel high temperature insulating material, the mechanical strength height, and light weight effectively alleviates the weight of pipe body; The outer shell layer of carbon steel tube not only can play the effect that thermal insulation layer and refractory layer are supported in protection, and price significantly reduces with respect to the 310S stainless steel.
Adopt the beneficial effect that technique scheme produced to be: 1), to alleviate impact, reduced the engineering time of hot air duct, reduced stop frequency, improved the utilization of capacity of production of carbon black to shell owing to used refractory layer and thermal insulation layer; 2) good heat preservation performance, thermal loss is few, energy saving, traditional metallic conduit adopts the heat-preservation cotton insulation, and heat insulation effect is relatively poor; 3) maintenance cost is low, long service life, and thermal shock resistance is strong; 4) hot air duct adopts refractory layer, the thermal insulation layer of alumina hollow ball and the outer shell layer of carbon steel that white fused alumina is built by laying bricks or stones, and is cheap.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises carbon steel tube 3, the brick refractory layer of building 1 of white fused alumina that also comprises the thermal insulation layer 2 of the alumina hollow ball of being located at carbon steel tube 3 inwalls and be located at described thermal insulation layer 2 inwalls.
The utility model has not only reduced thermal loss, and has greatly reduced the cost of hot air duct with carbon steel tube composite fire layer and thermal insulation layer, has prolonged working life.
To sum up, adopt the utility model after, improved the thermal insulation property of hot air duct, the air temperature after the preheating up to 650 ℃～850 ℃; Through hot air duct, the heat that is lost only has about 1%, has not only saved the energy, and has improved the output and the quality of carbon black.
