Problems solved by technology

Although the relatively pure decomposition and separation of coal substances has been realized, the output of the product is limited by the rotating kiln body, and the effect of internal heating pipes to heat the pulverized coal outside the pipes is not ideal, which cannot meet the production needs of rapid decomposition and separation.
In addition, the heating mechanism is arranged inside the kiln body, which increases the difficulty of its installation and maintenance, and is also not conducive to safe production

Abstract

The invention discloses an in-tube propelled coal material decomposition device, which includes a sealed kiln, a coal material propelled decomposition tube is installed in the kiln, the coal material propelled decomposition tube is provided with a coal feeding port, a coal discharging port and a decomposition gas collection tube, a heat exchange chamber is formed between the coal material propelled decomposition tube and an inner wall of the kiln and connected with a high-temperature gas heating mechanism via an intake tube, in the invention, the coal material propelled decomposition tube is installed in the kiln, so much hot air in the high-temperature kiln surrounds the coal material propelled decomposition tube, and transmits and radiates to pulverized coal in the coal material propelled decomposition tube, the pulverized coal fully absorbs the heat to be warmed and decomposed, and the pulverized coal is decomposed into a fuel gas, a tar gas and a coal having a higher heat value in the coal material propelled decomposition tube.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of coal substances, energy saving and emission reduction, and in particular relates to an in-pipe push type coal substance decomposition equipment. Background technique [0002] Among the known technologies, there are those that use coal to produce gas, some that use coal to produce natural gas, and those that use coal for high-temperature, medium-temperature, and low-temperature coking and gas production. Screening block materials will increase the cost of raw materials, or the calorific value of the produced gas is not high, the added value is not large, and the economic and social benefits are not significant. The heating method of the furnace can be divided into external heating type, internal heating type and internal heating and external heating mixed type. The heating medium of the external heating furnace is not in direct contact with the raw materials, and the heat is i...
