Sealing elements are arranged between the air guide pipe 15 and the air suction valve 14 and between the air guide pipe 15 and the control pipeline 30, so that good air tightness between the dust mask 10 and the air guide pipe 15 is ensured. In addition, a filter assembly (not shown) may be provided in the blower 12 to serve as a backup filter in case of emergency.
The exhaust part 13 is further provided with an exhaust valve (not shown in the drawing), and the exhaust gas and the surplus air volume are discharged to the outside through the exhaust valve 13, so that the exhaust gas can be efficiently discharged by maximally using the breathing power of the person himself.
In addition, because the air led out from the compressed air pipe cannot be directly comfortable for people to breathe, in order to reduce the humidity and the temperature of the air led out from the underground compressed air pipe, as a preferable scheme, the embodiment designs and prepares the moisture absorbent which is used in a matched mode, and the moisture absorption performance of the moisture absorbent is related to the temperature and the relative humidity of compressed air, so that the moisture absorbent suitable for the compressed air environment is required to be prepared in the scheme of the embodiment;
although vermiculite is poor in moisture absorption capacity as a moisture absorbent matrix, the macroporous structure of the vermiculite ensures that the calcium chloride is fully utilized in the liquefaction process, and the improvement of heat storage capacity (the increase of compressed air temperature) and the prevention of solution leakage can be both considered. Although vermiculite itself has little moisture absorption property, it itself has hydrophilicity and excellent pore structure. Vermiculite/40% CaCl2The composite moisture absorbent has moisture absorption capacity per unit mass1.94 g and vermiculite/40% CaCl2The semi-moisture absorption time of the composite moisture absorbent is 733.69min, which is second to the A-type water-resistant silica gel, and the initial moisture absorption rate is 0.0026 g/(g/min). Therefore, in various composite moisture absorbents, vermiculite/40% CaCl are adopted2A composite moisture absorbent.

Drying the filtered vermiculite coated with calcium chloride in a constant-temperature oven at 373K until the moisture absorbent does not decrease, and obtaining solid residue which is the vermiculite/40% CaCl2Composite moisture absorbent, which is prepared by mixing the obtained vermiculite with 40 percent of CaCl2And sealing the composite moisture absorbent, and storing in a shade place for later use.
The working principle of the compressed air power individual dustproof device of the embodiment is as follows:
when the first adjusting member V1 at the compressed air pipeline 40 is opened, compressed air flows into the filtering and dehumidifying assembly 20 along the compressed air pipeline 40, and then the compressed air firstly enters the diversion speed reduction part through the first through hole 231 to leave part of liquid water and rust impurities between the inner cover 22 and the upper cover 23; then, the compressed air enters the filter cartridge 60 filled with the chemical desiccant through the second through hole 221 and the air inlet of the filter cartridge 60 to be filtered and dewatered; the air filtered by the filter cartridge 60 is continuously fed to the wearer by the air supply parts 12 at both sides of the insulated mask 10 through the control duct 30 connected to the connection hole 214 of the case of the filtering and dehumidifying module 20, and the second adjusting means V2 is disposed within a distance that the wearer can take by himself during the work, so that the air flow rate in the insulated mask 10 can be adjusted to a comfortable state at any time using the second adjusting means V2. The waste gas and the redundant air volume are discharged from the exhaust part 13 along with the expiration, and the whole compressed air power individual dustproof device is always in a positive pressure state in the working process.
The dust-proof device is suitable for dust prevention of the fixed stations with serious dust pollution such as underground crusher drivers, uses the fresh air flow of the underground compressed air self-rescue system as an air source, utilizes compressed air power as air supply power, adjusts the temperature, humidity and speed of the air flow through the filtering device, and continuously and stably sends fresh air into the mask worn by workers through the pipeline, thereby effectively improving the breathing environment of the workers at the fixed stations of the mining working face.
