Abstract
The utility model discloses a flat-flame and radiation heating furnace for asphalt and comprises a furnace body, burners, a furnace tube and an air preheater. The flat-flame and radiation heating furnace is characterized in that a plurality of burners are arranged at the two sides of the furnace body; the furnace body is internally provided with the S-shaped furnace tube and the air preheater is arranged above the furnace tube; a plurality of separation walls are arranged at the two sides of the inside of the furnace body; the top part of the furnace body is fixedly connected with a chimney. The flat-flame and radiation heating furnace adopts the separation walls to divide the furnace body into a plurality of furnace sections and used the combination method of flat flame direct heating and radiation heating to heat the materials inside the tube section by section, therefore, the temperature rising rate of the furnace can be controlled and the furnace temperature can be conveniently regulated; the flat-flame and radiation heating furnace has simple structure, convenient operation and maintenance, continuous heating, high production efficiency and stable quality and is applicable for large-scale continuous production.
Description
Technical field
The utility model relates to the heating installation of Chemical Manufacture, specifically a kind of pitch flat fire process furnace.
Background technology
Produce mid-temperature pitch and modified pitch in the prior art, in order to ensure the quality of products, when it is heated, need strict controlled temperature and heat-up rate, method commonly used is to adopt single still intermittently to heat to mid-temperature pitch, modified pitch is then needed with the continuous method that heats of many stills, and this heating means production cycle is long, and thermosteresis is big.Also have at present and adopt tubular oven to heat to pitch, its structure is the centre that boiler tube is arranged in stove, dependence is installed in stove bottom boiler tube and furnace wall intermediary burner forms attached wall flame, rely on thermal radiation that the working medium in managing is heated behind the heating furnace wall, though have the characteristics of continuous heating, the production efficiency height is fit to large scale continuous prod, but it is uncontrollable to the temperature rise rate in the stove, the bituminous difficult quality guarantee.
Summary of the invention
The purpose of this utility model is a kind of pitch flat fire process furnace that provides at the deficiencies in the prior art, and it can control temperature rise rate and furnace temperature in the stove, has the characteristics of continuous heating, the production efficiency height, and steady quality is fit to large scale continuous prod.
The concrete technical scheme that realizes the utility model purpose is:
A kind of pitch flat fire process furnace comprises body of heater, burner, boiler tube, air preheater, and characteristics are that burner is several, is arranged on the body of heater both sides; Be provided with S shape boiler tube in the body of heater, the boiler tube top is provided with air preheater; The intravital both sides of stove are provided with several partition wall; The affixed chimney in body of heater top.
The utility model adopts partition wall to be divided into several stove sections in the stove, utilize mode that flat flame direct heating and radiation heating combine with the material zone heating in the boiler tube, it can control the temperature rise rate in the stove, convenient furnace temperature of regulating each stove section, simple in structure, operate, safeguard all very convenient, characteristics with continuous heating, the production efficiency height, steady quality is fit to large scale continuous prod.
