Description

Water smoke and aerosol dual-purpose type nozzle
Technical field
The invention belongs to processing depositing dust field, especially relate to a kind of water smoke and aerosol dual-purpose type nozzle.
Background technology
In many processings, majority can use dust-settling technology, and dust-settling technology mainly contains two kinds of water smoke and aerosol dust fallings now.Aerial fog nozzle is two-fluid spray nozzle, air pressure and hydraulic pressure need to be used and depositing dust effect could be realized, hydraulic spray nozzle is to rely on the water of certain pressure to clash into nozzle generation mist, and this kind of nozzle do not need air pressure, but the atomizing effect of hydraulic spray nozzle is less than the atomizing effect of aerosol.
The air compressor machine that often can run into supplying water mist nozzle in the process using in reality breaks down and affects the use of hydraulic spray nozzle, once and the supply gas circuit of aerial fog nozzle goes wrong, can not use, thereby directly affect on-the-spot production.Simultaneously existing atomizer is all single nozzle, can not accomplish that a nozzle had not only met the function needs of hydraulic spray nozzle but also can meet the function needs of aerial fog nozzle.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of water smoke and aerosol dual-purpose type nozzle, both can reduce the use accessory of dust falling system, can reduce again dust falling system fault and occur and out-of-work time and probability.
For solving the problems of the technologies described above, the technical solution used in the present invention is: water smoke and aerosol dual-purpose type nozzle, it comprises nozzle body, on described nozzle body, have water inlet, this water inlet is communicated with by eccentric orfice with the top of a current eddy flow passage, the center line of the center line of described eccentric orfice and current eddy flow passage is angle, and the bottom of current eddy flow passage is communicated with a jet, has several air swirl grooves along the outside scattering in axle center of described jet;
Between nozzle body inside and current eddy flow passage, ring is established an air swirl passage, and this air swirl passage one side is in communication with the outside by air inlet, and air swirl channel bottom is communicated with described air swirl groove simultaneously;
The bottom of described jet and air swirl passage is all in communication with the outside by the atomization mouth having on nozzle body.
Further, the middle and upper part of described air swirl passage one side is in communication with the outside by air inlet.
Further, the diameter of air swirl passage is greater than the diameter of the atomization mouth being communicated with it.
Further, the channel width of described air swirl channel bottom is less than other part channel widths of this air swirl passage.
Further, the center line of described air swirl groove is all acute angle with the axis of atomization mouth.
Further, described jet is circular, and its diameter is less than the diameter of current eddy flow passage.
Further, the diameter of described jet is less than the diameter of atomization mouth.
Further, water inlet, current eddy flow passage and jet coaxial line.
Further, water inlet, current eddy flow passage, air swirl passage, jet and atomization mouth coaxial line.
Advantage and good effect that the present invention has are:
1, the dual-purpose use number of fitting parts that has reduced dust falling system of a mouth, has effectively saved processing cost.
2, reduce dust falling system fault and occur and out-of-work time and probability, can accomplish still can carry out depositing dust work for unsaturated vapor in the situation that, improved operating efficiency and the working effect of depositing dust.
3, convenient to the voltage supply device spot check in dust falling system, and do not affect the lasting use of nozzle.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
Embodiment mono-:
As shown in Fig. 1,2,4 and 8, water smoke and aerosol dual-purpose type nozzle, it comprises nozzle body, on described nozzle body, have water inlet 1, this water inlet 1 is communicated with by eccentric orfice 2 with top or the sidepiece of a current eddy flow passage 3, the center line of the center line of described eccentric orfice 2 and current eddy flow passage 3 is angle, and the bottom of current eddy flow passage 3 is communicated with a jet 7, has several air swirl grooves 6 along the outside scattering in axle center of described jet 7;
The design of described eccentric orfice 2 is when entering into current eddy flow passage 3 the certain pressure in the situation that for water, water can do high speed centrifugation rotation around current eddy flow passage 3, the current of high speed centrifugation rotation are when through jet 7, and rotary water current high-speed impact jet 7 finally produces water smoke;
Between nozzle body inside and current eddy flow passage 3, ring is established an air swirl passage 4, the middle and upper part of these air swirl passage 4 one sides is in communication with the outside by air inlet 1, and air swirl passage 4 bottoms are communicated with described air swirl groove 6 simultaneously, and the channel width of described air swirl passage 4 bottoms is less than other part channel widths of this air swirl passage 4;
Describedly all be in communication with the outside by the atomization mouth 14 having on nozzle body for circular jet 7 and the bottom of air swirl passage 4, and the diameter of air swirl passage 4 is greater than the diameter of the atomization mouth 14 being communicated with it, the center line of described air swirl groove 4 is all acute angle with the axis of atomization mouth 14 simultaneously, and the diameter of described jet 7 is less than the diameter of current eddy flow passage 3 and the diameter of atomization mouth 14;
