Background
CN 107717744 a, entitled "a metal dust management and control system", including a wet dedusting system suitable for metal polishing working environment and said metal dust management and control system, wherein: the wet dedusting system comprises: an independent workshop, a PVC soft plastic door curtain, a water curtain device, an air curtain device, a high-power exhaust fan, a dust adsorption pool at the bottom of a working area, a dust filtering device at the rear part of the working area and a bottom water outlet; the PVC soft plastic door curtain is positioned on the front surface of the outer wall of the workshop and used for allowing workers to enter and exit the working area and sealing the working area so as to prevent dust from escaping into the whole workshop; the water curtain device is used for continuously sending the water source subjected to the circulating filtration into the adsorption tank at the bottom of the working area, so that the metal dust can be immediately adsorbed by the water; the air curtain device sucks clean air into the working area from the outside and is matched with the exhaust fan above the rear part of the working area, so that an effective air flow is formed in the working area, and the metal dust generated by polishing continuously rushes to the adsorption pool at the bottom due to the air flow; the high-power exhaust fan is positioned above the rear part of the working area and used for adsorbing mixed gas of dust and air in the working area by the adsorption tank and filtering the mixed gas by the rear filtering device, discharging the mixed gas out of the working area and forming effective air flow together with the air curtain device; the bottom dust adsorption tank is used for storing water from the water curtain device and adsorbing metal dust generated by polishing; the bottom water outlet is positioned on the right side of the bottom adsorption tank and is used for pumping the sewage after dust adsorption out of the adsorption tank for filtering and recycling; the dust filtering device at the rear part of the working area comprises two layers of baffles, a coarse filtering net and a fine filtering net and is used for removing extra dust which is not adsorbed by the bottom adsorption tank, so that clean air can be exhausted by the air exhauster. The disadvantages are that: the metal dust management and control system is not only complex in structure, but also high in installation difficulty and manufacturing cost; secondly, this kind of metal dust management and control system adopts "waterfall" formula water curtain, and it is more that it not only removes dust required basic water yield, and the energy consumption is bigger moreover.
SUMMERY OF THE UTILITY MODEL
The design purpose is as follows: for avoiding not enough among the background art, design a metal dust separator that not only can separate out the metal dust that mix with in the air current, the energy consumption is few moreover, use cost is low, simple to operate simultaneously, set up the position flexibility.
The design scheme is as follows: the design purpose is realized.
1. Be equipped with metal dust separator and metal dust separator in the inner chamber of dust removal jar and be located between the air inlet and the gas outlet of dust removal jar, the design that a water curtain shower nozzle was installed respectively to the body both sides that is responsible for and transversely sets up in the inner chamber of dust removal jar in the person in charge of among the metal dust separator is one of the technical characteristics of the utility model. The purpose of this design is: inputting the air flow with the metal dust into an inner cavity of the dust removal tank through an air inlet, then enabling the metal dust to rise along with the air flow and pass through a water curtain wall formed by spraying of a water curtain spray head, capturing the metal dust in the air flow by water molecules in the process, enabling the metal dust and water to fall to the bottom of the dust removal tank under the action of gravity, enabling the treated air flow to continue to rise and be discharged outside through an air outlet of the dust removal tank, and realizing separation treatment of the metal dust, namely realizing pollution-free discharge of the gas with the metal dust; in addition, in the device, because the water is continuously sprinkled from top to bottom and the airflow with the metal dust flows from bottom to top, both the water curtain and the airflow in the vertical direction are under the action of gravity, the water curtain is less prone to be blown away upwards by the airflow, and the metal dust is more prone to be captured by water molecules under the influence of gravity (the rising speed of the metal dust is obviously reduced); in addition, because the transverse section area of the inner cavity of the dust removing tank is large, water sprayed out simultaneously through the plurality of water curtain nozzles forms a water curtain wall on the transverse section of the inner cavity of the dust removing tank, and the requirements on the water pressure and the water outlet angle of the water sprayed out by the water curtain nozzles are greatly reduced.
