Problems solved by technology

The weak point of this action is: while wasting a large amount of energy that can be used again, it increases the amount of garbage and increases the amount of transportation.
Increases the burden on the dump and takes up valuable land

Embodiment Construction

[0006] The present invention is described in further detail below in conjunction with embodiment:

[0007] 1. In a closed inclined-plane-shaped channel, a blower mechanism is installed at the lower part, and an exhaust mechanism is arranged at the upper part. The mixture of coal ash and coal slag is extruded (note, not pulverized) while being conveyed by a screw conveying extrusion device, and dropped into a 200-mesh vibrating sieve for sieving. The second and third types of the aforementioned coal ash and cinder mixture are difficult to be crushed and screened out because of their high hardness, and can be used as building materials and other purposes. What is left is a mixture of coal char and fine coal ash.

[0008] 2. Coal ash and cinder are blown and sucked during the process of falling and sieving. The useless coal ash is sucked away by the strong wind, and what remains is the required coal char of the present invention.

[0009] 3. Mix 20-30% of raw coal, 5-10% of ch...

Abstract

A production method of Composite and renewable coal and its usage, solving that people always forsake coal cinder as waste in the present technology. The inadequacy of this is: while wasting a lot of energy which can be second used, also increasing quantity of rubbish, increasing quantity of transportation. Increase the burden of dumping grounds, occupy valuable land. Its characteristic is that coke is extracted from coal cinder and coal ash, then matched with run-off-the-mine, charcoal powder, yellow soil, calcined lime, calcium dioxide, soil nitre and kalium permanganicum according to appreciable proportion to be mixed uniformly, forming coal is produced and it can be used. Its good quality is: utilization of waste material. while saving a lot of energy which can be second used, also decreasing quantity of rubbish, decreasing quantity of transportation. Decrease the burden of dumping grounds and land occupying. Its fixed carbon is more than no smoke broken run-off-the-mine which is the kind of Zero number. The cost is low. Coal ash can directly put in soil after burned, improving soil. Social effects, social effects, environment effects are significant. It can be used to produce forming coal for burning.

Description

[0001] Field [0002] The invention relates to a method for producing coal and its application, in particular to a method for producing composite regenerated coal and its application. Background technique [0003] There are roughly four substances in the cinder and ash mixture generated after coal combustion. The first kind is pure ash, and its hardness and specific gravity are all lower than coal coke, are unnecessary in the present invention. The second type is the strange-shaped particles and lumps formed by the burning of metal minerals. Its hardness is several times higher than that of coal char, and its specific gravity is also larger than that of coal char. The third type is the bubble-shaped particles produced by the burning of metal and non-metallic minerals. Its specific gravity is the same as that of coal char, but its hardness is higher than that of coal char. The fourth category is exactly the reburnable substance utilized by the present invention-coal char. It...
