As shown in fig. 1 to 3, the embodiment provides a humidifying device, the device includes a body 1, the body 1 is longitudinally penetrated and provided with a humidifying channel 1-1 for passing a medium to be humidified, a liquid storage cavity 1-2 is arranged inside the body 1, the liquid storage cavity 1-2 is located at the periphery of the humidifying channel 1-1, and a wall surface of the humidifying channel 1-1 is provided with a nozzle communicated with the liquid storage cavity 1-2; the outer wall of the body 1 is provided with a water inlet for communicating the liquid storage cavity 1-2 with an external water source. Wherein, the medium to be humidified can be but is not limited to fly ash. The following describes a method for using the humidifying device in this embodiment, taking fly ash as an example:

When in use, one end of the body 1 is firstly fixed at the outlet of the dust removal and ash discharge valve 7, namely, the inlet of the humidifying channel 1-1 is communicated with the outlet of the dust removal and ash discharge valve 7; then the liquid storage cavity 1-2 is communicated with an external water source, the liquid storage cavity 1-2 is continuously filled with water of the external water source, and the water entering the liquid storage cavity 1-2 is continuously sprayed into the humidifying channel 1-1 under the action of water pressure; then, the dust removal and discharge valve 7 is opened. Due to the existence of the device, the dust discharged from the dust removal and discharge valve 7 flows through the humidifying channel 1-1 before entering the box car, and the dust is gradually sprayed into the water of the humidifying channel 1-1 to cover and humidify when flowing through the humidifying channel 1-1, so that the dust in the dust removal process can be prevented from generating dust. Therefore, the device not only can play a role in suppressing dust in the dust removal loading process, avoid environmental pollution and improve safety, but also has the advantages of simple structure, convenience in operation and low cost.

Furthermore, in order to improve the humidifying effect, the contact area between water drops in the humidifying channel 1-1 and dust is increased, and the spray holes are connected with the atomizing nozzles 2 in a matching mode. Wherein, the atomizing nozzle 2 is preferably a spiral atomizing nozzle. Certainly, in order to facilitate later maintenance and replacement, the atomizing nozzle 2 is detachably connected with the spray hole. For example, the spray hole is a threaded hole, and the atomizing nozzle 2 is provided with an external thread matched with the threaded hole in a threaded manner.

Preferably, the top end of the body 1 is provided with a flange 3 to facilitate the connection of the body 1 with a dust removal and ash discharge valve 7. Besides the flange connection, the body 1 and the dust removal and discharge valve 7 can be connected by screw connection or welding.

Preferably, the water inlet is communicated with an external water source through a liquid supply pipe 4, and a liquid supply valve 5 is arranged on the liquid supply pipe 4. During loading, an operator can control the opening degree of the liquid supply valve 5 according to the size and the opening degree of the dust removal and ash discharge valve 7, namely, the operator can adjust the water quantity sprayed into the humidification channel 1-1 by the spray holes according to the flow of the dust removal ash discharged by the dust removal and ash discharge valve 7. Specifically, the method comprises the following steps: when the flow of the dust-removing ash entering the humidifying channel 1-1 is larger, the opening degree of the liquid supply valve 5 can be adjusted to be larger; when the flow of the dust-removing ash entering the humidifying channel 1-1 is small, the opening degree of the liquid supply valve 5 can be adjusted to be small. Set up like this and can not only avoid the dust removal ash flow too big time because of the not enough emergence dust phenomenon of humidification, also can avoid the dust removal ash flow too little time because of the humidification excessively wastes water resource moreover. Of course, in order to facilitate accurate adjustment of the opening of the liquid supply valve 5, the liquid supply pipe 4 is further provided with a flow meter 6.

Preferably, the material of the body 1 may be, but is not limited to, stainless steel.

Preferably, the number of the spray holes is plural, and the plural spray holes are arranged at intervals along the axial direction and the circumferential direction of the humidification passage 1-1. Wherein, the body 1 can adopt a dividing wall type structure. For example, the body 1 includes an outer tube 1-3, an inner tube 1-4, an upper ring cap and a lower ring cap; the outer pipe 1-3 is sleeved outside the inner pipe 1-4 to form an annular cavity together with the inner pipe 1-4; two ends of the annular cavity are respectively covered with an upper ring cover and a lower ring cover to form a liquid storage cavity 1-2. At the moment, the inner tube 1-4 is equivalent to the humidifying channel 1-1, the space formed by the inner tube 1-4, the outer tube 1-3, the upper ring cover and the lower ring cover is the liquid storage cavity 1-2, and the spray holes are directly formed in the inner wall of the inner tube 1-4. During manufacturing, the sizes of the inner tubes 1-4 and the outer tubes 1-3 and the number of spray holes can be set according to the size of the dust removal and ash discharge valve 7. For example, when the diameter of the dust and ash removing valve 7 is 250mm, an inner tube 1-4 with the diameter of 300mm and an outer tube 1-3 with the diameter of 350mm can be selected, two layers of spray holes with the diameter of 2mm are arranged on the inner wall of the inner tube 1-4 along the axial direction of the inner tube 1-4, and 8 spray holes are uniformly distributed along the circumferential direction of the inner tube 1-4 in each layer.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
