The specific embodiment
Structure forms: shown in Fig. 1, water pipe 1 front end is equipped with magnetic valve 2, water pipe rear end is the water hose nozzle 5 of closing in shape, in water hose nozzle front side, be provided with air nozzle 4, air nozzle is connected with air pump 3, water hose nozzle is placed in a side of atomization chamber 6, supersonic generator 7 is housed in atomization chamber, at atomization chamber opposite side, electric heater 8 is housed, electric heater is provided with air jet pipe 9, in the outside of electric heater air jet pipe, dry fog emanator 10 is housed, magnetic valve, air pump, supersonic generator and electric heater are connected with PLC controller 11 by wire respectively.
PLC controls: shown in Fig. 2, flow sensor 12 is housed in water pipe, flow sensor is connected with signal receiving end 11.2 circuit that arrange in PLC, signal receiving end by the electrical signal transfer of flow sensor to PLC controller chip 11.1, be connected with triggering signal output 11.3 with controller chip, magnetic valve, air pump, supersonic generator and electric heater receive after triggering signal, the chain program of enrolling according to chip is moved, flow sensor, magnetic valve, supersonic generator is connected with power line 13 with electric heater, on the power line being connected with electric heater, add temperature regulating switch 8.1.
According to the flow velocity of water in water pipe, by the chip of PLC, set magnetic valve aperture, air pump rotating speed, the power of supersonic generator, and the startup of heater.Realize factor and control, thereby realize Automatic Control, make dry fog generator in optimum Working.
The thermosistor wherein installing additional between power line and electric heater can regulate the operating temperature of electric heater, thereby regulates the size of dispersing temperature and water content of dry fog.
The course of work of the present invention:
Open water solenoid valve, current arrive water hose nozzle place, now, the gases at high pressure that air pump produces are by the water effect in air nozzle and water hose nozzle, make the preliminary atomization of water smoke, form water smoke, under the ul-trasonic irradiation that water smoke produces at supersonic generator, water smoke is further pulverized, form tiny nanoscale atomizing particle, atomizing particle is through the air jet pipe ejection of electric heater, under hot effect, water smoke density reduces, water content reduces, expansion multiple strengthens, form the low dry fog of water content, dry fog diffuses in the environment containing dust through dry fog emanator, dust-laden particle is adsorbed, condense and effect of gain, thereby the density of dust in reduction surrounding air, play and purify air, prevent the effect of dust harzard.
The duty of magnetic valve, air pump, supersonic generator and electric heater is set by PLC controller.
Feature of the present invention:
PLC controller is controlled: adopt PLC controller to make the overall operation because of number control device with flow rate of water flow, realized automatic control.Compare with decentralised control, can reduce operate miss, make device operation chain, improve effect, and make device in best duty.
Reduce water and heat energy loss: compare with former water-spraying dust removal device, can save a large amount of water.Especially boiler adopts the desulfurizing dust-collector of spray not only to waste water, and also makes a part of thermal loss simultaneously, has reduced the thermal efficiency of boiler.
Reduced the labour cost bringing because of cleaning coal pond: use former water spray dust-arrest device, need to drop into a large amount of manpowers and clear up, and adopt dry fog generating means of the present invention to carry out depositing dust, can effectively reduce the recruitment consumption bringing because of cleaning coal pond.
Use without freezing: existing dust arrester, because freezing winter, cannot use throughout the year.If use cloth-bag type dedusting, cloth bag is frozen, impact is ventilative.Adopt dry fog generating means of the present invention not have icing problem.
Minimizing expense: for the discharge of dust, all will pay environmental protection fine not up to standard.When adopting dry fog generating means of the present invention, dust emission is processed through dry fog, and air quality meets discharge standard, reduces the expense of paying dust emission expense.
