Abstract
A liquid for harnessing coal-mine gas is composed of water solution of phosphoric acid three (2, 3-) ester, fluohydric acid, sodium hypochlorite. The liquid can be heated and volatilized to the mine, can reduce the mine temperature, prevent gas from burning and explosion, reduce mine dust concentration, and effectively harness the gas in the mine and improve the mine safety.
Description
Affiliated technical field
The present invention relates to a kind of material of administering coal mine mash gas, particularly a kind of liquid substance.The invention still further relates to a kind of device that is used to deposit this material.
Background technology
Device in Gas is a kind of inflammable and explosive pernicious gas that produces in the Coal Production process, and the coal master will be to use the concentration of monitoring instrument real time monitoring Device in Gas at present, and reduces the concentration of fire damp gas by the ventilation fan air draft.This means can't be implemented effectively to administer to Device in Gas, when monitoring mash gas concentration when exceeding standard, can only the emergency evacuation personnel in the pit, and strengthen the down-hole and ventilate to disperse Device in Gas, can not be used to prevent the blast of Device in Gas.
Chinese patent 03126296.1 discloses a kind of liquid that prevents the Device in Gas blast, is to use in the pressure vessel of packing into after multiple cold-producing medium and the extinguishing chemical mixing.Behind fire damp gas concentration over-standard, can with spray liquid on work plane, effectively reduce downhole temperature and mash gas concentration, make Device in Gas not reach explosion limit, ensure the safety of mine.
But more than invention is the urgent emergency measure of a kind of coal mine mash gas when exceeding standard suddenly, and is not suitable for the improvement of low concentration Device in Gas in the colliery at ordinary times.Yet coal mine mash gas exceeds standard and the moment occurrence of blasting often, usually has little time to implement urgent preventive action.So, when coal mine mash gas concentration is low, just it is administered, be only the effective means of preventing the coal mine mash gas blast.
Summary of the invention
Purpose of the present invention just provides a kind of liquid of administering coal mine mash gas, is used at ordinary times colliery low concentration gas gas being administered, and with the concentration of control coal mine mash gas, reduces gas explosion accident.
Improvement coal mine gas gas-liquid of the present invention is made up of the material mixing of following portions by weight:
Tricresyl phosphate (2,3-two chloropropyls) ester 300～400
Hydrofluoric acid 30～50
Clorox 60～90
Benzoic acid 20～40
Carbon tetrachloride 20～40
Water 1500～3000
The liquid storage that the present invention forms above-mentioned mixing is in the device of a closed container, by the heating panel in the device liquid is heated, it is constantly evaporate in the mine, play and reduce temperature and the effect that stops the Device in Gas combustion explosion in the mine, reach the purpose of administering Device in Gas.
The device of depositing improvement coal mine gas gas-liquid of the present invention is a closed container that is connected to form by casing and loam cake, and wherein loam cake is provided with an inlet and several steam vents, and liquid is joined in the casing by inlet; A light source is installed, to promote that mixing material issues biochemical reaction at illumination condition in casing; In the bottom interlayer of casing electric hot plate is installed also, is used for liquid heating in the casing, the liquid evaporation back after the heating by on the steam vent that covers be drained in the mine; The same circuit of the common use of light source and electric hot plate.
The present invention has installed the spring pressure control valve in the steam vent of device, steam vent is closed at ordinary times, when liquid in container is heated to a certain degree, when reaching certain air pressure in the container, volatilization gas backs down the spring pressure control valve, and volatilization gas is discharged in the mine.By adjustment to the spring pressure control valve, can control steam vent and under different pressure conditions, be opened, thus the capacity of control liquid.
Dust in the mine is more, also has little object at any time and falls, and these things fall into steam vent, all steam vent might be stopped up.Therefore, the present invention has increased a protecting wire net lid again on steam vent, to guarantee the unimpeded of steam vent.
For ease of regularly casing being cleaned, the present invention has also settled a leakage fluid dram in the bottom of casing.
As required, can be lifted on device of the present invention the top of mine, also can the handle assembly fixed placement on the ground, can also install road wheel in the bottom of device, it is moved freely, to adapt to the use under the different occasions.
Among the present invention, the liquid that is used to administer coal mine mash gas is made simple, and processing cost is low, cooperate its device of depositing liquid to use, can in effective time, reduce mash gas concentration and mine temperature in the colliery, prevent gas explosion accident, regulation effect is remarkable, and mine safety improves greatly.
Use liquid of the present invention and device, can also reduce the dust concentration under the mine effectively, reduce environment pollution, for Environmental security provides safeguard.
