Because the gas sucked into the carrier is dry gas, the aluminum ash in the carrier cannot generate hydrolysis reaction to generate toxic and harmful gas, so that the breathing device 3 can also prevent the toxic gas from being discharged into the atmosphere to cause serious pollution.
Preferably, in the specific implementation, the end, which is communicated with the inner space of the carrier 1, of the second filling pipe 323 can be covered with dust-collecting filter cloth, the action of which is consistent with that of the particle filtering material 01, and the detailed description is omitted, so that when the gas enters and exits the carrier 1, particles in the gas can be further filtered, and the gas filtering effect is improved.
In summary, when the aluminum ash is required to be transported, the aluminum ash is stored in a carrier, the carrier can be a closed type transportation device such as a container, a bulk container or a tank body of a powder particle material transport vehicle, in the transportation process, the aluminum ash and moisture in the air undergo hydrolysis reaction so as to generate mixed gases such as hydrogen sulfide, phosphine, ammonia and the like, the gases enter a filtering device from an air inlet device, and after being absorbed by absorbing agents in the filtering device, the absorbing agents in the hydrogen sulfide, the phosphine, the ammonia and the peculiar smell in the gases sequentially, the air outlet device discharges the filtered gases outside the carrier, so that serious pollution to the atmosphere caused by the gases generated by the hydrolysis reaction between the aluminum ash and the moisture in the air in the transportation process is effectively prevented, when a filtering system is blocked and other faults occur, the breather valve sucks the gas outside the carrier into the communicating pipe, when the gas passes through the communicating pipe, the drying agent and the particle filtering material filled in the communicating pipe filter the moisture and the particles in the gas, so that the gas entering the carrier keeps dry and has no impurity, thereby inhibiting the reaction rate of aluminum ash in the carrier, when the gas pressure in the carrier reaches a certain value, the breather valve stops sucking the gas, and simultaneously the gas in the carrier is exhaled by the breather valve, and the carrier is decompressed in time, so as to prevent the hidden danger of explosion caused by the overlarge gas pressure in the carrier when the filtering system fails, therefore, as the gas sucked into the carrier is dry gas, the aluminum ash in the carrier can not be hydrolyzed, namely the toxic and harmful gas can not be decomposed, namely, the breather valve has the function of decompressing the carrier, and meanwhile, the breather valve can not cause serious pollution to the environment, greatly improves the safety and environmental protection of the product.
The foregoing is merely exemplary of the present utility model and is not intended to limit the present utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, or the like, which is within the spirit and principles of the present utility model, should be included in the scope of the claims of the present utility model.
