Description
Technical field
The present invention relates to aerosol dust falling equipment, particularly a kind of industry spot liquids and gases of realizing mix the aerosol dust falling system that reaches the depositing dust purpose.
Background technology
At present, because industrial dust is the key factor that influences industrial environment,, need carry out measures such as effective depositing dust and dust suppression to industry spot for to site environment and the able-bodied consideration of staff.
Traditional dust-removing method mainly contain following some:
1, electric precipitation: its equipment is huge, and it is many to expend metal material, needs high-voltage transforming and rectifying installation, invests higher; Simultaneously the technical merit of making, installing and managing is had relatively high expectations; Efficiency of dust collection is influenced greatly by dust specific resistance, and when dust resistance is excessive or too small, if do not take certain measure, efficiency of dust collection will be affected; Do not possess off-line maintenance function, in case equipment break down, can only shutdown maintenance, otherwise will move in spite of illness.
2, bag-type dust: being used to purify when containing the strong dust of mist of oil, water smoke and caking property has corresponding requirements to filtrate; Sack cleaner purifies needs explosion precaution when explosion danger being arranged or having the dusty gas of spark; When being used to handle the high dusty gas of relative humidity, need take insulation measure (particularly winter), in order to avoid cause " sticking with paste bag " because of dewfall; When being used for purifying when being corrosive gas, need select suitable corrosion-resistant filtrate for use; Be used to handle high-temperature flue gas and need take cooling measure, below the temperature that the cigarette temperature drop be can bear to the filter bag long-term operation, and adopt resistant to elevated temperatures filtrate as far as possible.
3, water mist dust-removing: the filtering accuracy for the water source is had relatively high expectations, and does not reach easy blockage phenomenon when requiring when filtering precision; Cross when low when hydraulic pressure, it is insufficient to spray water smoke, and dust-laying effect is undesirable; When hydraulic pressure was too high, easy damaged equipment also caused the equipment cisco unity malfunction; Need take the insulation measure winter, otherwise bursting by freezing easily.
Therefore, providing a kind of industry spot liquids and gases of realizing to mix the aerosol dust falling system that reaches the depositing dust purpose, is one of the current urgency of this field scientific research personnel difficult problem to be solved.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, be embodied as the removing of industry spot dust, the dust pelletizing system that a kind of atomizing effect is good, water-saving performance is good, pipeline is difficult for obstruction, the pressure modulability is good is provided.
The technical solution adopted in the present invention is for achieving the above object:
A kind of aerosol dust falling system is characterized in that described system comprises at least one aerosol control cabinet and external pipeline system and sprayer unit; Described aerosol control cabinet comprises control system, liquid control module and gas control module; Described external pipeline system comprises liquid line and gas piping, and described sprayer unit is located at the junction of liquid line and gas piping, for reaching the terminal device of depositing dust purpose; Described aerosol control cabinet is an aerosol dust falling system control centre, realizes the collection and the pressure of liquids and gases are regulated by liquid control module and gas control module; The liquid line that described external pipeline system comprises and gas piping respectively with the aerosol control cabinet in the liquid control module link to each other with the gas control module, realize to the filtration of liquids and gases and to the opening and closing of gas-liquid two-way.
Described liquid control module is connected and composed by parts such as water pump, strainer valve, electric node manometer, pressure regulator, check valves.
Described gas control module is connected and composed by parts such as air compressor machine, air accumulator, strainer valve, pressure regulator, check valves.
Described liquid line is connected and composed by parts such as strainer valve, hand valve, magnetic valves.
Described gas piping is connected and composed by parts such as strainer valve, hand valve, magnetic valves.
That described sprayer unit is selected is circular, wide-angle is circular, 360 ° of annulars, fan-shaped and deflection is fan-shaped and make and spray the shower nozzle of particle diameter between 1 μ m-10 μ m.
Aerosol control cabinet of the present invention is by inner liquid control module and gas control module, realizes to the collection of liquids and gases with to its open and close controlling; Liquid is by the water pump supercharging in the aerosol control cabinet and enter the liquid main line, strainer valve at first enters filtration to liquid on the liquid main line, then pressure regulator is adjusted to fluid pressure the pressure limit that is fit to the normal operation of system, the break-make of check valve control liquid, when check valve is opened, liquid enters the outer liquid line of case, and when closed check valve, liquid stops to enter the outer liquid line of case; Gas enters air compressor machine in the case by the air inlet of aerosol control cabinet, go into air accumulator through overcompression is laggard, realization is to the collection of gas, strainer valve on the gas main line filters gas, then by pressure regulator gas pressure is adjusted to the pressure limit that is fit to the normal operation of system, the break-make of check valve control gas, when check valve is opened, gas enters the outer gas main line of case, and when closed check valve, gas stops to enter the outer gas main line of case; Case inner control system can control the operation of whole system and stop, and when change-over switch was got to auto state, the switching value signal of control system receiving sensor was controlled the start and stop of magnetic valve, and realizes the time-delay control to magnetic valve; When change-over switch knocked manual state down, the staff can carry out control operation to magnetic valve by the band button on the panel.
The invention has the beneficial effects as follows:
Be directed to the dedusting method of other form, as bag-type dust, dry dust removal, electric precipitation etc., the less investment of aerosol dust pelletizing system equipment, easy to operate, the automaticity height, floor space is little, and water consumption is little, and operating cost is low, non-secondary pollution.
Compare the water mist dust-removing system that generally adopts at present and have incomparable advantage especially:
(1) atomizing effect is good, and aerosol dedusting particle water diameter is 1 μ m-10 μ m, only is 1/10 of water mist dust-removing particle, combines with the dust molecule easilier, reaches the purpose of dust suppression.
(2) water-saving performance is good, and the aerosol dedusting fully atomizes water, and injection flow rate only is 1/8 of a water mist dust-removing, and it is wet excessively that this has just guaranteed coal can not to be beaten in dedusting, thereby avoid the coal spout phenomenon of blocking.
(3) pipeline is difficult for stopping up, because the flushing water that adopt at power plant or harbour mostly is a secondary recovery water, contains certain impurity in the water, and the time has been grown, and causes equipment such as pipeline, nozzle, magnetic valve to stop up easily, thereby influences the normal use of entire equipment.In the aerosol dust pelletizing system, by programme-control, regularly use the high pressure draught flushing pipe, the prevention line clogging has avoided the interior ponding of pipeline to freeze simultaneously.
(4) the pressure modulability is good, and the aerosol dust pelletizing system has disposed booster water pump, air pump, simultaneously pressure-regulating device has been installed on pipeline, can regulate water, atmospheric pressure in the pipeline easily, thus the control spray effect.
