Description
Technical Field
The utility model relates to the technical field of dust removal, in particular to a high-efficiency inertial sand remover.
Background
The inertial sand remover is a dust removing device which enables air to be purified to collide with a baffle plate or change the direction of air flow sharply, and separates and captures sand and dust by utilizing inertial force. The inertial sand remover is also called an inert sand remover, and mainly makes the air to be purified rapidly turn or turn again by means of a baffle plate, wherein the movement track of sand particles is difficult to change rapidly due to the inertial action, and the movement track cannot be changed as rapidly as the air flow, so that the sand particles and the baffle plate are separated.
The Chinese patent publication No. CN204709957U discloses an inertial sand remover, which comprises a ventilating duct 11, wherein an air inlet of the ventilating duct 11 is arranged at the right end, and an air outlet is arranged at the left end, as shown in FIG. 1. The air duct 11 is internally provided with a collecting box 12 with an opening facing the air inlet of the air duct, and a flow guiding shutter 13 which not only plays a role in wind and sand filtration but also guides sand and dust to the collecting box 12 is arranged between the collecting box 12 and the pipe wall of the air duct 11. After dirty air with large dust content enters from the air inlet of the ventilating duct, the air is bent twice under the action of the guide vane 131 of the guide shutter 13, clean air flows out from the other side of the guide shutter, particles in the air move linearly under the action of inertia, even if smaller particles do not flow out along with the air through bending twice under the action of inertia at a certain speed, the particles finally fall into the collecting box 12 and are discharged through the fan 14, and fine particles in negative pressure floating in the collecting box 12 are not returned to a rear air pipe but are discharged along with the fan 14 under the action of the fan.
The chinese patent publication No. CN208574346U discloses a gas-solid separator, as shown in fig. 2, the gas-solid separator is composed of two V-shaped side plates 21, each side plate 21 is provided with a plurality of equidistant inclined blades 22, and a guide hole 23 is formed at the position of the inclined blades 22 projected on the side plate 21, and a tortuous channel is formed by the inclined blades 22 and the guide hole 23. When the gas enters between the two side plates 21 from the left side of the sand remover, the tortuous passage formed by the inclined blades 22 and the flow guiding holes 23 can filter sand and dust in the air to be purified and collect the sand and dust into the collecting box 24..
Because the inertia sand remover has a plurality of passageway that can discharge clean air, along the direction of gas flow, the velocity of flow of gas can reduce gradually, and the inertia that sand dirt granule received in the gas can reduce gradually, and too much sand dirt granule can pile up near collecting box opening under the effect of gravity, and sand dirt collection efficiency reduces, influences the air current in the air pipe, can change the motion trail of sand dirt granule. The existing inertial sand remover is characterized in that two rows of guide vanes are arranged in a V shape, so that the ventilation area near the collection box can be reduced, the flow speed of air to be purified is constant when flowing in the ventilation channel, and sand particles are ensured to have enough inertia to enter the collection box.
Because the separation of the dust particles of the gas box is completed under the action of rapid steering, as shown in fig. 1 and 2, two rows of guide vanes are arranged in a V-shaped manner in the ventilating duct, so that although the flow speed of air to be purified in the second half section of the air inlet channel can be improved, part of the dust particles can strike the surfaces of the guide vanes, the guide vanes can change the movement track of the dust particles, so that the dust particles cannot move into the dust box, and the kinetic energy of the dust particles under the action of the flow speed can be converted into internal energy when colliding with the guide vanes, so that the movement speed of the dust particles is reduced, and the dust particles cannot smoothly enter the dust box; in addition, because the sand and dust particles strike at the guide vane, the movement direction of the sand and dust particles is changed, and partial sand and dust particles can outwards escape through a tortuous channel, so that the filtering effect of the sand remover is poor and the filtering efficiency is low. Meanwhile, due to the V-shaped arrangement, noise can be generated when sand particles strike the guide vane, and if no measures are taken subsequently, the noise can be transmitted to the air supply side.

The top guide plate is arranged to be an inclined side wall, in addition, sand and dust particles can be acted by gravity and inertia when entering the air inlet channel, the movement track of the sand and dust particles in the air inlet channel is similar to a parabolic curve with a downward opening, and the movement track of the sand and dust particles is matched with the inclination of the top plate, so that the area of the air inlet channel is reduced by adopting the top plate, the condition that the sand and dust particles collide on the top plate is avoided, and the movement track of the sand and dust particles can be prevented from being changed by the top plate.
In this embodiment, the two rows of V-shaped blades are disposed parallel to each other and equidistant, and the top of each V-shaped blade in the air inlet channel contacts with the top baffle 38, and since the top baffle 38 is disposed obliquely in the moving direction of the air to be purified, the top baffle 38 tapers to reduce the area of the air to be purified that can flow in the air inlet channel as the air to be purified approaches the primary collection box, so as to ensure that the air to be purified has sufficient flow velocity, and that the sand has sufficient inertia, so as to ensure that the sand is blown into the primary collection box. In addition, the sand particles can be acted by gravity and inertia when entering the air inlet channel, the movement track of the sand particles in the air inlet channel is similar to a parabolic curve with a downward opening, and the movement track of the sand particles is matched with the inclination of the top guide plate 38, so that the area of the air inlet channel is reduced by adopting the top guide plate 38, the condition that the sand particles collide on the top guide plate 38 is avoided, and the movement track of the sand particles can be prevented from being changed by the top guide plate 38. The central baffle may be provided in this embodiment.
Example six
Referring to fig. 9, the other embodiments are the same as the first embodiment except that the central baffle 35 is provided with two inclined side walls 352 facing the two baffle louvers 33, and the positive X-axis end of the inclined side walls 352 is inclined at a set angle to the side of the air to be purified with respect to the negative X-axis end.
The inclined sidewall 352 gradually decreases the ventilation area of the air inlet channel 31 along the positive direction of the X-axis, and meanwhile, since the inclined sidewall is far away from the air guiding louver and the taper of the inclined sidewall is small, even the impurities changing the movement track of the sand will not cause the sand to escape from the air guiding louver.
Example seven
Referring to fig. 10, the other embodiments are the same as the first embodiment, except that each of the above-mentioned flow-guiding shutters is provided with a non-uniform flow-guiding hole assembly, the non-uniform flow-guiding hole assembly includes a plurality of flow-guiding channels 331 located at different positions along the X-axis direction, and the sizes of the plurality of flow-guiding channels 331 sequentially arranged along the X-axis positive direction gradually decrease along the X-axis direction.
In this embodiment, two rows of V-shaped blades are arranged horizontally, and the width of the tortuous path formed between two adjacent V-shaped blades gradually decreases along the direction of movement of the air to be purified. When the air to be purified enters, the inertia of the sand particles is large at the beginning, so that the inertia of the sand particles is not changed due to the large interval between the V-shaped blades at the beginning, and the sand particles still move to the primary collection box at a higher speed. As the sand speed decreases, the spacing between the V-shaped blades also decreases, and the difficulty in air flow out increases, so that the sand is less likely to change inertial direction. This ensures that the direction of inertia of the sand particles does not change and enters the primary collection box in a straight line. The central baffle may be provided in this embodiment.
The non-uniform baffle orifice assembly described above may also be applied to the first through sixth embodiments described above, with the adjustment of the required segments depending on efficiency, or may be one segment. The length of each segment is the distance that the sand inertially flows.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present utility model will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present utility model.
