Problems solved by technology

This not only causes a huge waste of resources, but also a large amount of asphalt fume is discharged into the atmosphere, causing serious pollution to the environment.
For this reason, people use electric membrane dust collectors to treat asphalt flue gas. Due to the huge amount of flue gas and the extremely high temperature, it is difficult to handle it, and it is often unsatisfactory after being treated by electric membrane dust collectors.
[0004] The green body roasting of carbon products is carried out in the coke bed, and a large amount of fine-grained coke needs to be added as filler when the furnace is loaded, which seriously affects the working environment on site

Embodiment Construction

[0024] Illustrate in conjunction with the following examples with the carbon product roasting furnace involved in the present invention:

[0025] Example ： Roast and press blanks with the carbon product roasting furnace involved in the present invention, put 20 pieces of carbon product blanks formed by isostatic pressing of φ200×500 into the furnace hearth of the roasting tank 1 in a naked shape, and do not use granular coke as the charging charge when charging the furnace. The technical conditions of the compact are shown in Table 1.

[0026] Table 1 Technical conditions of compact

[0027]

[0028] Start the vacuum pump 2 to evacuate the system. The vacuum degree of the system should reach above -0.09 MPa and maintain for 1 hour. After closing the valve of the vacuum line, nitrogen gas was introduced. Slowly increase the pressure, and the system will increase the pressure in the system to 0.02MPa(G) through the pressure control valve 5, and the pressure will be automa...

Abstract

The invention relates to an industrial furnace for roasting carbon products, which comprises a roasting pot, a condenser, a connecting pipe, a vacuum pump, and pressure control valves; The roasting pot comprises a housing, a cover, a gasket, a heating element, and a thermal insulation layer; the condenser comprises a container and a condensing tower; the pressure control valves are respectively mounted at a protective gas inlet of the roasting pot and a gas outlet at the top of the condenser, and can ensure the operation of the system at a micro-positive pressure. The connecting pipe is a metal pipe lined with a thermal insulation layer. During system operation, vacuum-pumping is carried out firstly to discharge all the air, and protective gas is injected; during the whole roasting period, the system is maintained to be airtight so as to realize effective control of the roasting atmosphere. The roasting furnace of the invention solves the problems of difficult roasting of large-size carbon products, large pollution, and the like.

Description

technical field [0001] The invention relates to industrial furnace equipment for roasting carbon product green bodies. For the treatment of materials or articles belonging to International Patent Classification C 01 B31 / 04. Background technique [0002] The roasting furnace is an industrial furnace for high-temperature heat treatment of carbon product compacts under the protection of fillers, and can also be used for re-heat treatment of carbon products impregnated with pitch. In short, the pitch in the blank is carbonized by roasting, so that the carbon product has high mechanical strength, low resistivity, good thermal stability and chemical stability. The roasting furnace is an important equipment in the production of carbon products. Over the years, carbon product manufacturing enterprises have mostly used open-type industrial furnaces such as ring furnaces with covers, tunnel kilns or drawer kilns, and the fuels are mainly producer gas, natural gas or coal. [0003] A...
