Abstract

<P>PROBLEM TO BE SOLVED: To separate dust coal containing sulfur content into sulfur and dust coal. <P>SOLUTION: In the sulfur separator, a positive charged body 1 is electrified by positive charge, and the sulfur content in the dust coal containing sulfur content is electrified by negative charge; and the sulfur-containing dust coal is brought into contact with the rotating positive charged body 1. The sulfur content attached on the positive charged body is removed at a separate site. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to separating pulverized coal and sulfur in pulverized coal.

An application has been made to separate pulverized coal and sulfur by the force of wind.

Divide pulverized coal containing sulfur into pulverized coal and sulfur.

The positively charged body is made into plastic electricity, the sulfur content in the pulverized coal containing sulfur is made into a negative electron, and the pulverized coal containing the sulfur content having a negative electron is launched from the bottom or brought into contact with it. Blow up to make contact, or strike from the side to make contact, or spray from the side to make contact or drop from the top to make contact with the sulfur content plus the pulverized coal falls on the charged body, so the sulfur content is removed elsewhere. Can separate sulfur and pulverized coal.

Sulfur and pulverized coal can be separated.

BEST MODE FOR CARRYING OUT THE INVENTION

The positively charged body 1 made of glass and the negatively charged body 2 made of rubber are brought into sliding contact with each other and rotated in the same direction so that electricity is applied to pulverized coal containing sulfur to give negative electricity to the sulfur, and the impeller 4 The pulverized coal falls on the positively charged body 1 that is rotated in a circular shape in cross section and only has a sulfur content, and the pulverized coal falls off with kelen 5 at another place.

In some cases, a lump of glass is put into pulverized coal containing sulfur, and the glass is removed by a net to give the sulfur a negative electricity.

The positive charging body 11 is brought into contact with the negative charging body 12 and rubbed to make positive charging. One part of the belt conveyor 13 is brought into contact with one part of the body, and the thickness of the pulverized coal containing sulfur is reduced between the parts, and the pulverized coal is naturally dropped from the folded part of the belt conveyor, and the positively charged body 11 Remove sulfur adhering to other places.

Positively charged body 43 (example) using a fur conveyor as a belt conveyor, contacting the belt conveyor with a negatively charged body 42 (example) ebonite and rubbing it, placing pulverized coal containing sulfur on the downstream side to form a thick layer The pulverized coal is naturally dropped at the turning point of the belt conveyor, and the sulfur content adhering to the lower side of the belt conveyor is removed elsewhere.

Claims (1)

The negatively charged body (2) is brought into contact with the positively charged body (1) and rotated so that the contact surface rubs, and the pulverized coal containing sulfur is placed on the belt conveyor (3), and current is passed through the pulverized coal to cause sulfur. Sulfur separator characterized by separating the pulverized coal and sulfur by the electrostatic force by making the minute charge negative and bringing the pulverized coal into contact with the positive charge.
