Abstract
Disclosed is a raw oil preheater for a soot carbon production line with 40000-ton annual yield. A circle of heat exchange tube bundle is uniformly distributed on the inner wall of a cylinder, a flue gas outlet is arranged at the end of the side wall of the cylinder, and an elbow at the flue gas outlet is provided with an inspection hole. The raw oil preheater has the advantages that heat exchange effect is improved effectively, preheated raw oil temperature reaches 180 DEGC-250 DEG C so that technical requirements are met, flue gas pipelines and a heat exchanger body are more convenient to clean, and soot carbon dust does not deposit inside heat exchanger, so that affection to heat exchange effect is reduced.
Description
Technical field
The utility model relates to a kind of preheater, relates in particular to the fuel oil preheating device of 40,000 tons of production of carbon black lines of a kind of annual output.
Background technology
At present, the domestic fuel oil preheating device modular system that does not still have 40,000 tons of/year ripe carbon black devices, used fuel oil preheating device is to develop on the basis of original 20,000 tons of/year production lines and come at present.The weak point of this equipment is the heat exchange weak effect, and the feedstock oil temperature after the heat exchange can not reach technological requirement.
Summary of the invention
The purpose of this utility model has been to provide the fuel oil preheating device of 40,000 tons of production of carbon black lines of a kind of annual output, improves the heat exchange effect of fuel oil preheating device, guarantees that the feedstock oil temperature can satisfy technological requirement.
The utility model is achieved like this, it comprises cylindrical shell, heat exchanging pipe, gas approach, exhanst gas outlet, it is characterized in that cylinder inboard wall is evenly distributed with a circle heat exchanging pipe, and the front end of cylindrical shell is a gas approach, the rear end sidewall of cylindrical shell has exhanst gas outlet, has inspection opening on the elbow of exhanst gas outlet.
Technique effect of the present utility model is: the heat exchange effect is obviously improved, feedstock oil temperature after the preheating reaches 180-250 ℃, satisfies technological requirement, makes the cleaning of flue gas pipeline and heat exchanger body more convenient, carbon powder dust has reduced the influence of heat exchanging effect not in the heat exchanger inside deposition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Cylindrical shell 2, heat exchanging pipe 3, exhanst gas outlet 4, gas approach in the drawings, 1.
The specific embodiment
As shown in Figure 1, the utility model is achieved like this, the front end of cylindrical shell 1 is a gas approach 4, cylindrical shell 1 inwall is evenly distributed with a circle heat exchanging pipe 2, the rear end sidewall of cylindrical shell 1 has exhanst gas outlet 3, have inspection opening on the elbow of exhanst gas outlet 3, hot flue gas enters preheater from preheater gas approach 4, after carrying out heat exchange with feedstock oil in the heat exchanging pipe 2, flue gas flows out from exhanst gas outlet 3, and exhanst gas outlet 3 is opened at sidewall, avoid carbon powder dust to deposit to and stopped up exhaust gases passes in the heat exchanger, influence the flue gas circulation, or bury heat exchanger tube, reduce heat exchange efficiency.On the exhanst gas outlet elbow, open inspection opening, be convenient to make regular check on the carbon powder dust of deposition in the cleaning pipeline, improve service life.
