Embodiment 1

[0023] The coal-water slurry production equipment provided by the invention is made of wear-resistant polished stainless steel. It is 1.5 meters high and 0.5 meters in diameter. It is equipped with 8 layers of rotors and 8 layers of orifice plates. The rotational speed of the rotatable shaft can be controlled at 3000-5000 rpm. figure 2 ), the blade is a regular wedge-shaped arc-shaped surface (such as Figure 4 ), the feed size of raw coal is about 10-20 cm, and the amount of water injected is 40% (based on the total weight of the product coal-water slurry). After passing through the equipment, it will eventually become a coal-water slurry containing 200-300 mesh fine coal particles from the discharge port , can be directly transported to the power plant and directly used as fuel for the power plant.

Abstract

The invention refers to a kind of device for producing water coal pulp, which includes shell and material inlet or outlet, transferable shaft, there sets several rotors in the shell centre and shaft lengthwise, each rotor couples and connects with the shaft through shaft cover, the hole board is set between the rotors and vertical to the shaft, the exterior margin connects with the sidewall of the shell, the inner margin is a centre ring shape, there has a distance to the shell, the exterior margin is regular or irregular star shape polygon, one side of the rotor board has at least two vanes. The muzzle layer is set on the cross-sectional under the shell and has 30-60degree. The structure is special, the volume is small, the frequency is high, the quantity of product is large, it can produce water coal pulp or oil coal pulp with high efficiency, it also can be used for crushing metal mineral chemical solid materials, side product.

Description

technical field [0001] The invention relates to an equipment for producing coal-water slurry, in particular to an equipment for producing coal-water slurry or oil-coal slurry through airflow shock wave crushing technology and a production method thereof. Background technique [0002] Coal is the most abundant solid fossil fuel in the world. It is distributed in countries all over the world, such as China, North America, Australia, South Africa, Russia, Europe, etc. There are a lot of storage and mining. However, people have always used solid raw coal as fuel and rarely processed it. Processing or still in the form of solid raw coal has been used until now. The main reason is that coal is solid, which is not easy to process, refine and transport like oil and natural gas; raw coal mining and transportation are difficult and expensive. The chemical structure of raw coal itself is extremely complex, mostly composed of polycyclic aromatic hydrocarbons or heterocyclic aromatic hyd...
