Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
For being more fully understood that the present invention, in the present invention, the right in Fig. 1 is the front portion of wet scrubber, and the left side in Fig. 1 is the rear portion of wet scrubber.
The basic thought of the present invention is: providing a kind of wet scrubber, for development machine, the defecator 4 of this wet scrubber is installed on air duct elbow 6, and compact conformation saves the length space of wet scrubber；The dehydration device 2 of this wet scrubber is in tilted layout, and is installed on casing 3 internal, and the dehydration device 2 being in tilted layout is more beneficial for dehydration when development machine goes up a slope, and improves dewatering efficiency.
As shown in Figure 1, a kind of wet scrubber of the present invention, including blower fan 1, dehydration device 2, casing 3, defecator 4, water injector 5, air duct elbow 6, blower fan 1 is the power of dust in providing suction tunnel, defecator 4 is for Chalk-dust filtering, water injector 5 is for spraying water to defecator 4, air duct elbow 6, casing 3 and blower fan 1 set gradually (being from right to left shown in Fig. 1) by the direction of air inlet 7 to the air outlet 9 of wet scrubber, defecator 4 and water injector 5 are mounted at air duct elbow 6, and water injector 5 is preposition arranges in defecator 4, it is internal that dehydration device 2 is arranged at described casing 3.
Preferably, dehydration device 2 is obliquely installed in the inside of casing 3, and its one end is fixing with the top of casing 3 to be connected, and its other end is fixing with the bottom of casing 3 to be connected.Owing to dehydration device 2 is in tilted layout, increase the dehydration area of dehydration device 2, especially when development machine equipment goes up a slope and runs, be more conducive to dehydration device 2 and be dehydrated, improve dewatering efficiency.Embodiment as shown in Figure 1 is dehydrated device 2 be tilted to the right setting, but dehydration device 2 can also be tilted to the left setting in other embodiments, the incline direction of dehydration device 2 is not limited by the i.e. present invention, and the form that arranges of dehydration device 2 changes direction when specifically can run according to development machine climb and fall.
Simultaneously, as shown in Figure 1, the right-hand member of air duct elbow 6 connects the air inlet 7 of wet scrubber, the left end of blower fan 1 is provided with air outlet 9, dust in tunnel enters in air duct elbow 6 by air inlet 7, after water spray, filtration and dehydration, finally, the pure air after filtration is discharged by institute's air outlet 9.
Additionally, it is worth mentioning that aforementioned wet scrubber also includes blowdown apparatus, blowdown apparatus specifically includes dredge pump, the bottom of casing 3 is provided with the sewage draining exit 8 for effluent sewerage, and one end of blowdown apparatus is connected with this sewage draining exit 8, and described dredge pump provides power for effluent sewerage.It should be noted that be not limited in dredge pump for what effluent sewerage provided power, it is also within the scope of the present invention that other can realize power set of this technique effect, and differ a citing at this.
In the present invention, the operation principle of wet scrubber is specific as follows: first, blower fan 1 provide power, and dust in tunnel is sucked wet scrubber；Secondly, air duct elbow 6 is entered through air inlet 7；Again through defecator 4 Chalk-dust filtering, little granule dust is filtered；Then, spraying water to defecator 4 by water injector 5, settle after moistening for dust, the fluid of band dust proceeds to casing 3；Then, dehydration device 2 being dehydrated, be stored in casing 3, all of sewage is discharged by sewage draining exit 8, and blowdown apparatus is provided power by dredge pump；Finally, pure air is discharged by air outlet 9.
