Multitube heating rotary pulverized coal pyrolysis system

Abstract

The invention discloses a multitube heating rotary pulverized coal pyrolysis system, including a feeder, an outlet gas gathering and distribution box, a preheater, a transmission mechanism, a rotating cylinder body, a heating pipe, a riding wheel device, an air inlet gas gathering and distribution box and a gas guiding device. The rotating cylinder body supports on the riding wheel device, and is driven by the transmission mechanism; a feed end of the rotating cylinder body is provided with the outlet gas gathering and distribution box, and a discharging end of the rotating cylinder body is provided with the inlet gas gathering and distribution box; The rotating cylinder body is provided with the heating pipe, both ends of the heating tube are respectively connected with the inlet gas gathering and distribution box and the outlet gas gathering and distribution box; the feeder is connected with the charging end of the rotating cylinder body through the gas gathering and distribution box; the gas guiding device is connected with the discharge end of the rotating cylinder through the gas inlet gathering and distribution box; and the feeder is installed on the upper part of the preheater, and is connected with the gas outlet gathering and distribution box. The invention realizes the scale pyrolysis of pulverized coal, and creates conditions for improving the comprehensive utilization and economic value of pulverized coal.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal pyrolysis equipment, and relates to a multi-tube heating rotary pulverized coal pyrolysis system, in particular to a multi-pipe heating rotary pulverized coal pyrolysis system with a preheater, which is mainly used in pulverized coal pyrolysis Coal deep processing and new coal chemical industry can realize large-scale pulverized coal pyrolysis treatment. Background technique [0002] Pulverized coal is a product that must be produced in a large amount when modern fully mechanized mining equipment is used in the coal mining process. Due to the high dependence on coal resources in my country's energy structure, more and more attention has been paid to the development and efficient utilization of coal resources including low-rank pulverized coal. This is to maintain the sustainable development of my country's economy and ensure energy security. important strategic move. Coal low-temperature ...

Problems solved by technology

[0003] However, the existing coal pyrolysis equipment is mainly used to process lump coal with a diameter greater than 20mm, and it is difficult to process small particle coal or pulverized coal with a diameter less than 20mm

At the same time, the single-unit processing capacity of existing dry distillation equipment is generally small, which cannot meet the requirements of large-scale production, and the overall economic efficiency and environmental protection performance are also poor, which is not conducive to the centralized disposal of pollutant emissions.

Due to the above-mentioned reasons, most of the precious small-particle coal resources are sold cheaply or piled up for disposal, which not only pollutes the environment, but also wastes resources.
