Problems solved by technology

Coal is the dominant source of basic energy. Coal is widely distributed in my country, and the quality of coal is relatively miscellaneous. There are also many types of coal with low grades, such as low calorific value, high moisture content, sulfur, mercury and other pollutants, which are harmful to coal-fired power generation and pollutants. Control is a big hassle

Embodiment 1

[0043] Such as figure 1 As shown, the coal electromagnetic radiation desulfurization and upgrading system of the present invention includes a feeding and conveying unit, a desulfurization medium feeding unit, a mixing unit, an electromagnetic radiation unit and a magnetic separation unit. The feeding valve of the material unit enters the mixing chamber of the mixing unit together with the desulfurization medium of the desulfurization medium feeding unit in the feeding valve, and enters the electromagnetic radiation unit after being fully mixed in the mixing chamber, and enters the magnetic separation after radiation treatment separate unit.

[0044] 1. Feeding and conveying unit:

[0045] Including coal loading machine, iron remover 1, conveyor belt 2, lower coal hopper 3, crusher 4 and hoist 5. The raw coal is introduced into the coal conveyor belt through the coal loading machine, and the conveyor belt is equipped with an iron remover. After the iron removal, the raw coal ...

Embodiment 2

[0061] The further design of this example is that the umbrella-shaped mixing disc 11 of the mixing unit is provided with only one layer, a total of 2. The rotating shaft of the mixing disc is connected with the driving motor, and each mixing disc is equipped with a driving motor.

Embodiment 3

[0063] The further design of this example is that the turntable of the mixing disc 103 of the electromagnetic radiation unit adopts an integral conical surface structure or a multi-blade conical surface structure, the angle β between the conical surface and the rotating shaft is 95-160°, and the surface of the turntable adopts an arc shape face or curved facet. Electromagnetic radiation reactor frequency 900-980MHz, power 25-100KW.

Abstract

The invention provides a coal electromagnetic radiation desulfurization upgrading system, aiming at reducing the content of sulfur in coal, improving the quality of sulfur coal resources and providingpreceding guarantee to ultralow emission. The system comprises a charge and delivery unit, a desulfurization medium feed unit, a mixing unit, an electromagnetic radiation unit and a magnetic separation unit, raw coal is delivered and upgraded through the charge and delivery unit and enters the feed valve of the mixing unit, enters the mixing cavity of the mixing unit with a desulfurization mediumof the desulfurization medium feed unit in the feed valve, is sufficiently mixed in the mixing cavity, enters the electromagnetic radiation unit, and enters the magnetic separation unit after radiation treatment.

Description

Technical field: [0001] The invention relates to a coal processing device, specifically a coal electromagnetic radiation desulfurization and upgrading system, which belongs to the technical field of coal processing. Background technique: [0002] As a primary energy source, the efficient and clean utilization of coal has always been the direction for the industry to strive for. Coal is the dominant basic energy source. Coal is widely distributed in my country, and the quality of coal is relatively miscellaneous. There are also many types of coal with low grades, such as low calorific value, high moisture content, sulfur, mercury and other pollutants, which are harmful to coal-fired power generation and pollutants. Control is a big problem. [0003] Therefore, research and development of a method and device for coal quality improvement treatment and source purification of pollutants can improve the quality of coal entering the boiler, improve furnace combustion, prevent corro...
