The free end of drainpipe extends to the top of purification tank;The frame is provided with the drive mechanism that driving cylinder slides up and down.
The principle of this programme waste gas dust-removal device is:
During by the device cleaning organic waste gas and dust, clear water is first added into purification tank, while can be filled in settling box
Qing Dynasty's water.Open flue gas leading, the then water that the organic exhaust gas and dust constantly discharged by flue gas leading will be constantly passed through in purification tank
In, so as to form bubble in water of the waste gas in purification tank, and the rising in water from the water surface until discharge.Waste gas shape in water
During into bubble, the dust mixed in the offgas will be adsorbed on the surface of bubble, and after bubbles burst is discharged from the water surface, dust still stays
In water, so as to carry out a certain degree of purification to waste gas.
During flue gas leading is passed through waste gas into purification tank, drive mechanism is also driving cylinder up and down reciprocatingly simultaneously
Slide.When cylinder up and down reciprocatingly slides, guide ring also follows cylinder while moved back and forth up and down;And guide ring is provided with
The guide pad coordinated with the spiral guide slot on precipitation cylinder, therefore when guide pad slides up and down relative to precipitation cylinder, in spiral
Under the guide effect of guide groove, guide pad can be simultaneously relative to precipitation cylinder reciprocating rotation.Because guide pad and cylinder pass through list
It is rotatablely connected to bearing, and cylinder is connected with dust-collecting bucket by click, so as to which when guide pad rotates, guide pad can band
Dynamic cylinder one-directional rotation.
In this programme, when guide pad moves up relative to precipitation cylinder, click will limit cylinder and rotate, from
And cylinder moves up only with respect to precipitation cylinder, because the valve element of valve is not affected by centrifugal action, therefore valve is closed, point
When being moved upward to the top from cylinder, disengagement chamber connects with leaking hole, so as to which the water in precipitation cylinder enters in disengagement chamber, and stores
In disengagement chamber.And when guide pad moves down relative to precipitation cylinder, guide pad will be by unilateral bearing to cylinder transmission
Moment of torsion, and click also rotates without limitation on cylinder, then during cylinder moves down, cylinder rotates simultaneously;
When cylinder rotates, the valve element of valve by centrifugal action by along the radially outward slip of cylinder so that valve is opened,
Therefore the water in disengagement chamber will be flowed into dust-collecting bucket by valve.And due to when cylinder rotates, the water in disengagement chamber also will be in
Swirl shape flows, and so as to which the impurity in water also will be subject to centrifugal forces, under the influence of centrifugal force, impurity is attached to separation
In the side wall of cylinder so that impurity will not enter in dust-collecting bucket, i.e., water is purified.Further, since cylinder is by dust-collecting bucket
Upper end closed, during cylinder moves down relative to dust-collecting bucket, the pressure made in dust-collecting bucket is increased, so as to will
Water in dust-collecting bucket extrudes from drainpipe, water is again returned in purification tank.
After water in settling box enters disengagement chamber, the water in purification tank will be caused to flow downward, then purify the water of trench bottom
Into in settling box, precipitated, and top is stayed in purification tank with respect to clear water, so as to reduce the water in purification tank
Dust.Because the sectional area of settling box is smaller, and the depth of the bottom of the water surface distance settling box in purification tank is also bigger, because
When this is passed through waste gas into purification tank, it is smaller to purify influence of the vibration of trough inner water to the water in settling box, i.e., in settling box
Water is relatively tranquil, beneficial to contamination precipitations such as dust.
In summary, by setting settling box so that when being passed through waste gas to purification tank, purify the vibration of trough inner water to heavy
The influence of water in the groove of shallow lake is smaller, therefore contributes in settling box to carry out precipitation process to water.And by setting cylinder, can be right
Water and impurity in settling box are further separated, and are returned it into purification tank and reused;And in cylinder not
When being rotated relative to precipitation cylinder, the water in settling box will enter in disengagement chamber, so that the water in purification tank flows downward, make net
The sewage of change trench bottom, which enters in settling box, to be precipitated, and the relative clear water entered in purification tank then stays in purification tank
In, to continue to purify waste gas, so as to reuse water, and suspension aniseed dust in the water of purification tank is prevented, led
Cause to reduce the detergent power of waste water.
Preferred scheme one:As the further optimization to base case, the purification tank and settling box pass through in back taper
Guide shell connection.Because guide shell upper end area is big, enter so as to be advantageous to purify the sewage of trench bottom in precipitation cylinder, and keep away
The water for exempting from purification tank endosexine is inhaled into precipitation cylinder.
Preferred scheme two:As the further optimization to preferred scheme one, the inwall of the cylinder is provided with detachably
Porous adsorption layer.When cylinder rotates, will be entered by the impurity that centrifugal force moves out in the hole in adsorption layer, with
Impurity is adsorbed, improves the separating effect to impurity.
Preferred scheme three:As the further optimization to preferred scheme two, the edge of the purification tank is provided with excessive groove, mistake
The upper end for spending groove is higher than the upper end of purification tank, and the free end of the drainpipe is located at the surface of excessive groove.Drainpipe first will
Water is discharged into excessive groove, then water will diffuse out after entering in excessive groove from the edge of excessive groove, and is entered in purification tank, due to purification
The vibration of water in groove close to edge is generally smaller, so as to avoid the water for just flowing into purification tank from being mixed with original water rapidly
Close, and immediately wicked into precipitation cylinder.
