For above-mentioned prior art, the utility model provides a kind of axial flow cyclone type gas-solid separator with solid collection device, can not only be efficiently that gas is separated with solid, and can be effectively by isolated solid collection in solid collection device, there is flow resistance less, simple in structure, the feature such as easy to operate

In order to solve the problems of the technologies described above, the technical scheme that the utility model is achieved with the axial flow cyclone type gas-solid separator of solid collection device is: this gas-solid separator, comprise shell separator, the porch of described shell separator is provided with swirl vane, the rear portion of described swirl vane, and be axially provided with gas vent passage along described swirl vane, described gas vent passage is by the gradual shrinkage taper cone barrel of arranging successively, rectifying tube and diffuser pipe form, the lower wall of described shell separator is communicated with solid passing away, described solid passing away and described gas vent channel vertical, described solid passing away is provided with solid collection device, the two ends of described solid collection device are respectively equipped with valve.

This is with the axial flow cyclone type gas-solid separator of solid collection device, and wherein, the gap between the outer rim of described swirl vane and the inwall of described shell separator is 10mm to the maximum.In described swirl vane, the edge of every blade is provided with the chamfering of 30～60 °, and before and after every blade, the angle of side is 30～60 °.The cone angle of described gradual shrinkage taper cone barrel is 30～90 °, and described diffuser pipe is flaring type taper cone barrel, and the cone angle of described flaring type taper cone barrel is 30～120 °.The two ends of separator are equipped with adpting flange.

Compared with prior art, the beneficial effects of the utility model are:

Gas-solid separator of the present utility model can not affect normal air feed in solid exclusion process by the distinctive solid collection device of collecting of the isolated solid high-efficiency rate of whirlwind separator, and gas flow resistance is little.Be mainly used in the devices such as gas-purification, industrial dedusting, air cleaning.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of axial flow cyclone type gas-solid separator with solid collection device of the utility model, comprise shell separator 1, the porch of described shell separator 1 is provided with swirl vane 7, and the gap between the outer rim of described swirl vane 7 and the inwall of described shell separator 1 is 10mm to the maximum.In described swirl vane 7, the edge of every blade is provided with the chamfering of 30～60 °, and before and after every blade, the angle of side is 30～60 °.The rear portion of described swirl vane 7 is also axially provided with gas vent passage along described swirl vane 7, described gas vent passage consists of the gradual shrinkage taper cone barrel 2 of arranging successively, rectifying tube 3 and diffuser pipe 4, the cone angle of described gradual shrinkage taper cone barrel 2 is 30～90 °, described diffuser pipe 4 is flaring type taper cone barrel, and the cone angle of described flaring type taper cone barrel is 30～120 °.The lower wall of described shell separator 1 is communicated with a solid passing away 5, described solid passing away 5 and described gas vent channel vertical, described solid passing away 5 is provided with solid collection device 6, the two ends of described solid collection device 6 are respectively equipped with valve, when cleaning solid collection device 6, make upper valve 81 and lower valve 82 alternations at two ends, to guarantee the normal production of whole system, during cleaning solid, upper valve 81 is opened, make solid fall into the solid collection device 6 between two valves, again upper valve 81 is closed, then open lower valve 82, solid is discharged gas-solid separator outside under the effect of combustion gas self pressure and gravity, thereby can safety dumping solid and guarantee that gas is without leakage.In addition, for the ease of the utility model gas-solid separator, be connected with pipeline and dismantle, at the two ends of separator, being equipped with adpting flange 9, also having guaranteed that thus axial flow whirlwind separator does not change the principal direction of gas flow.

The utility model with the course of work of the axial flow cyclone type gas-solid separator of solid collection device is: the high-speed gas containing solid particle enters from the gas access in shell separator 1 left side, the guide functions of the swirl vane 2 of process High Rotation Speed, utilize constant gas conservation of energy principle, the speed at gradual shrinkage conical tube place increases the dynamic pressure making herein and becomes large, thereby guaranteed that the static pressure of (A-A face center in Fig. 1) increases separator in center, the large end of cone, solid particle axial velocity is reduced, stoped solid particle to enter gas vent passage, solid particle produces the radial velocity along shell separator 1 wall, make solid particle move downward along wall the effect that solid collection device plays collection that enters.Solid particle rear continuation separated from the gas is moved along shell separator 1 inwall, part solid particle directly enters in solid collection device 6 by solid passing away 5, part solid particle is gathered on the outer surface of revolution of gradual shrinkage taper cone barrel 2 rear ends, when solid particle is stacked into a certain degree, under the Action of Gravity Field of himself, from this, the surface of revolution drops in solid collection device 6; Meanwhile, gas after separated with solid particle, that removed solid impurity directly enters into gas vent passage, because gas vent passage consists of the gradual shrinkage taper cone barrel 2 being connected in turn, rectifying tube 3 and diffuser pipe 4, be that gas vent passage is to be formed by connecting by gradual shrinkage taper cone barrel and small-bore cylinder and flaring type taper cone barrel, and what be positioned at latter end is flaring type taper cone barrel, therefore, this the pressure of gas of flowing through can be recovered accordingly, thereby completed the separated of gas and solid, reached the object of Purge gas.Under separator duty, upper valve 81 is in running order, and lower valve 82 is closed; When needs clean, upper valve 81 is closed, and lower valve 82 is opened, and solid particle relies on the interior pressure of pipeline and Action of Gravity Field to be discharged from.

Although the utility model is described in conjunction with figure above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that not departing from the utility model aim, can also make a lot of distortion, within these all belong to protection of the present utility model.
