Abstract
The present invention relates to a three-phase foam preparing system for preventing and controlling spontaneous combustion of coal, which comprises a stirrer, a foam generator and a filter, wherein the filter is orderly connected with the stirrer and the foam generator, the pipe wall of the foam generator is provided with an air inlet, the air inlet is connected with a nitrogen injecting machine or a mine air compressor through an air inlet pipe, a slurry injecting pipe connected with the inlet of the filter is provided with a by-pass pipe, and the tail part of the by-pass pipe is connected with a through pipe of an outlet of the foam generator. After the prepared slurry in the slurry injecting pipe passes through the filter with a filter screen, compressed air or nitrogen is compressed in the foam generator by the air compressor so that the slurry foams to form the gas-liquid-solid three-phase foam by using the nitrogen or the air as the gas phase. The system has the advantages of high foaming efficiency, convenient maintenance, convenient operation, favorable effect, small occupation space and volume and wide practicality, and the system can effectively prevent the slurry from blocking the pipe.
Description
One, technical field
The present invention relates to the three-phase foam preparing system that is used to prevent and treat spontaneous combustionof coal with a kind of, be particularly useful for the spontaneous combustion and the fire extinguishing of mine control coal.
Two, background technology
Spontaneous combustionof coal is one of main natural calamity of China's mine.Engineers and technicians in this field have developed the three-phase froth device of spontaneous combustionof coal for this reason, be applied to on-the-spot actual, and obtained effect preferably, but this device can only stir the generation three-phase froth, be not a whole set of preparation system that forms three-phase froth, need other auxiliary ligand complete equipment when therefore using.In addition, because the particular surroundings and the condition in colliery contain impurity or big solid particle in the slurries, the plugging phenomenon usually takes place in device, causes to form three-phase froth continuously.Because the defective of above two conditions, three-phase froth is restricted in the promoting the use of of mine.
Three, summary of the invention
In view of the deficiency of prior art, the invention provides with air or nitrogen and be gas phase, simple in structure, be difficult for the three-phase foam preparing system of the control spontaneous combustionof coal of plugging.
A kind of three-phase foam preparing system that is used to prevent and treat spontaneous combustionof coal of the present invention, it comprises agitator and foam maker, it also comprises the strainer that is linked in sequence with agitator and foam maker, and the tube wall of described foam maker is provided with air inlet port, and air inlet port is connected with by air inlet pipe and annotates nitrogen machine or mining air compressor machine; The described Grouting Pipe that is connected the filter inlet place is provided with bypass pipe, and the bypass pipe afterbody links to each other with the siphunculus of foam maker outlet.
A kind of three-phase foam preparing system that is used to prevent and treat spontaneous combustionof coal of the present invention, described strainer is made of communicating pipe and the screen pack of establishing in communicating pipe, communicating pipe, the bottom was provided with the sewage draining exit by valve control, and communicating pipe is provided with pressure meter, and the mesh size of screen pack is 50mm
2～80mm
2The entrance of described strainer is provided with valve, and the exit of the foam maker that is communicated with it is provided with valve; The entrance and the exit of described bypass pipe are equipped with valve; The air inlet port place of described foam maker is sequentially with non retern valve, pressure meter and valve.
A kind of three-phase foam preparing system that is used to prevent and treat spontaneous combustionof coal of the present invention is best suited for and puts out fast under the coal mine and the high-efficiency prevention and control Conflagration Caused by Coal Self-ignition.Adopt strainer, agitator and foam maker to be linked in sequence, air inlet port is set on foam maker, the air that can produce with air compressor machine is as gas phase, also can be with nitrogen as the vapor phase production three-phase froth, be not subjected to the restriction of nitrogen resource, the three-phase froth coefficient of foaming can reach 30～100 times after using air, thereby cost is reduced significantly.The Grouting Pipe that links to each other with strainer is provided with bypass pipe, and the bypass pipe afterbody links to each other with the siphunculus of foam maker outlet, can be used as auxiliary slurry pipeline excessively with this.Strainer in this system can effectively be removed impurity in the slurries and big solid particle; The pressure meter that is provided with can clearly show the pressure in each pipeline; Non retern valve can be avoided coagulating in compressed air line owing to the little slurries that make of pressure of gas; Whole system is simple in structure, can compressed air or nitrogen be gas phase, it is easy to use, and is effective, the volume that takes up room is little, has practicality widely in the present technique field.
