As preferably, described tank coupling has water-level gauge and water pump, and described water-level gauge is coupled in water pump, makes the liquid level of water pump in tank carry out water delivery lower than during lower limit to tank, until liquid level rises to higher limit.
As preferably, described capillary has many, and circumference is distributed in around described narrow air flue.
As preferably, above described rib block, also Zhang Youyi opens water strainer, and described water strainer covers the whole cross section of described dirt pocket inside; Further, described narrow air flue lower end also connects the jet pipe that a string has magnetic valve; Described magnetic valve opens and closes continuously with fixed frequency.
Beneficial effect of the present invention is: dusty gas operationally, is inputted described air inlet by blower fan by this energy-saving wet scrubber, and charge air flow forms high velocity air in described narrow air flue, rib block described in downward directive; In this process, according to fluid mechanics principle, the rapid drawdown of narrow air flue internal gas pressure, makes the water body in tank be inhaled in narrow air flue by described capillary, and together swashs rib block described in directive in company with dusty gas; When gas-liquid mixture high speed impact is on rib block, sputter atomization immediately, its principle is identical with medical atomizer; Thus make in dirt pocket, to be full of mist vapour, the dust granule in dusty gas fully can be surrounded, and is the nuclei of condensation with dust granule, formed large drop backward under drop, and to discharge from described drainpipe; Owing to being formed with water back bending in described drainpipe, so the air after dedusting can only rise to above dirt pocket, discharge from described gas outlet; Owing to not having extensive spray system in this deduster, the input quantity of water body is positively correlated with the air velocity in narrow air flue, that is is positively correlated with the input speed of dusty gas, so the wastage of water body is few; Visible, this deduster only needs a small amount of water, can remove dust granule less in dusty gas, has higher energy saving effect, can significantly reduce dedusting cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this energy-saving wet scrubber embodiment one.
Fig. 2 is the structural representation of this energy-saving wet scrubber embodiment two.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment one shown in Fig. 1, this energy-saving wet scrubber comprises dirt pocket 1, described dirt pocket 1 upper end has air inlet 10, described air inlet 10 inside forms the narrow air flue 100 being communicated with dirt pocket 1 straight down, and described narrow air flue 100 is downwards just to the rib block 2 be fixed in dirt pocket 1; And described narrow air flue 100 side direction vertical connection capillary 3; In the present embodiment one, described capillary 3 has two symmetries and is connected to narrow air flue 100 both sides, and capillary 3 is communicated to the tank 4 of liquid level lower than described narrow air flue port; The upper side of described dirt pocket 1 is to offering gas outlet 11; Dirt pocket 1 lower end is connected with drainpipe 5, and described drainpipe 5 forms a water back bending 51 below dirt pocket 1, to make can form water seal in water back bending 51.
Above described rib block 2, also Zhang Youyi opens water strainer 6, and described water strainer 6 covers the whole cross section of described dirt pocket 1 inside.
Dusty gas operationally, is inputted described air inlet 10 by blower fan by above-mentioned energy-saving wet scrubber, and charge air flow forms high velocity air in described narrow air flue 100, is passed down through described water strainer 6, and rib block 2 described in directive; In this process, according to fluid mechanics principle, the rapid drawdown of narrow air flue 100 internal gas pressure, makes the water body in tank 4 be inhaled in narrow air flue 100 by described capillary 3, and together swashs rib block 2 described in directive in company with dusty gas; When gas-liquid mixture high speed impact is on rib block 2, sputter atomization immediately, its principle is identical with medical atomizer; Thus make to be full of mist vapour below dirt pocket 1 inside, water strainer 6; Here, due to the existence of described water strainer 6, the mist vapour of formation is sputtered from described rib block 2, cannot upwards ascension and discharging from described gas outlet 11 always, when the ascension of mist vapour is to water strainer 6, the mist pearl in mist vapour just will condense on water strainer 6, make the dust granule in mist vapour be condensed on water strainer 6 together with moisture simultaneously, and only have the cleaned air after dedusting, water strainer 6 could be passed from gas outlet 11 and discharge; The layout of described water strainer 6, not only reduces the mist vapour that upwards ascension is escaped, and the mist vapour below water strainer 6 can be made more dense, is easier to catch dust granule.
In dirt pocket 1, because mist vapour is that suspended state surrounds dust granule, therefore having the sufficient time is the nuclei of condensation with dust granule, formed large drop backward under drop, and to discharge from described drainpipe 5; Owing to being formed with water back bending 51 in described drainpipe 5, so the air after dedusting can only rise to above dirt pocket 1, discharge from described gas outlet 11; Owing to not having extensive spray system in this deduster, the input quantity of water body is positively correlated with the air velocity in narrow air flue, that is is positively correlated with the input speed of dusty gas, so the wastage of water body is few; Visible, this deduster only needs a small amount of water, can remove dust granule less in dusty gas, has higher energy saving effect, can significantly reduce dedusting cost.
