Problems solved by technology

The harmless degree of pyrolysis products is the highest, and the value of the converted products is also high. However, because the treated object has no fluidity or poor fluidity, the heating uniformity in the heating process is very poor, and "overfire" and "cooked" are prone to occur. "The problem

Embodiment Construction

[0015] The process of heating the pyrolysis material by the metal heat carrier is carried out under closed conditions, and the corresponding equipment is a cavity container, which integrates the functions of heat carrier heating and material pyrolysis. When working, first put the solid fusible metal used as a heat carrier into the container, and then start the heat source outside the container to heat with external heat to melt the solid fusible metal into a liquid state. When the temperature reaches the required value, the material can be added into it, and through the action of external force, the molten metal heat carrier and the material to be processed are mixed and contacted, and the requirement can be realized.

[0016] The process method of the present invention conforms to the basic theory and basic principles involved in thermal engineering and chemical engineering, and the fusible metals involved are simple metal elements or their alloys, which are relatively cheap a...

Abstract

The invention relates to a fusible metal heat carrier heat transfer processing technology method, belongs to the field of industrial processing, the field of waste resource recovery and disposal and the practical technology in the scientific research test process, and can be used for the high-temperature pyrolysis processing process of materials. The method has a certain popularization prospect inlarge-scale processing of coal, oil sand and oil shale and requirements of harmless treatment technologies of organic matters such as waste tires, plastics and oil sludge. According to the method disclosed by the invention, a fusible metal in a molten state is used as a heat carrier working medium and is placed in a special container, an external heating type heat source is firstly used for heating, after the required temperature is reached, a processed material is added into the container, and a close contact mixed-phase state is formed under the action of external force, so that absorbed and accumulated heat is quickly and uniformly conducted to the processed material by the heat carrier, and the purpose of pyrolyzing the processed material is achieved.

Description

[0001] Technical field [0002] The invention relates to a fusible metal heat carrier heat transfer processing method, which belongs to the field of industrial processing, the field of recycling and disposal of waste resources and the practical technology in the process of scientific research and experimentation, and can be used in the high-temperature pyrolysis processing process of materials. In terms of large-scale coal, oil sand, oil shale processing and the demand for harmless treatment of organic matter such as waste tires, plastics, and oil sludge, it has certain promotion prospects. [0003] technical background [0004] Traditionally, the heat treatment of the above materials requires a temperature environment of hundreds or even thousands of degrees Celsius. During the heating process, the carbonization method in which the heat source is separated from the material is often selected. The carbonization method has the problems of slow heat energy transfer, long processi...
