The waste gas generated by burning coal as fuel used in power plant contains impurities such as fly ash, coal dust, SO2, NOx, CO, etc. to protect environment, SO the waste gas can be discharged to air after being purified, but when the waste gas is conveyed to the purifying liquid through the aeration plate 2, dust such as fly ash and coal dust in the waste gas can be suspended in the purifying liquid, and in the floating process of bubbles, the bubbles can be attached to the surface of the dust, SO the contact area between the bubbles and the purifying liquid is reduced, therefore the purifying effect is deteriorated, and with the increase of working time, the dust content in the purifying liquid is gradually increased, the contact area between the bubbles and the purifying liquid is further reduced, therefore, the purifying liquid needs to be replaced periodically, SO the workload of workers is increased, and the waste gas treatment work cannot be performed in the process of replacing the purifying liquid, SO the purifying efficiency is reduced; in order to improve the purification efficiency and purification effect, when purifying waste gas, firstly, the air inlet of the aeration plate 2 is communicated with the air outlet of the waste gas manufacturing device, then the motor 5 is started, at the moment, the motor 5 drives the second half gear 6 to rotate, when the gear teeth on the second half gear 6 are meshed with the gear teeth of the first half gear 4, the second half gear 6 drives the first half gear 4 to rotate so as to drive the stirring blades 3 to rotate forward and the clockwork spring 7 to accumulate force, when the gear teeth on the second half gear 6 are separated from the gear teeth of the second half gear 6, the clockwork spring 7 releases force and drives the stirring blades 3 to rotate reversely, so that the stirring blades 3 always rotate forward and backward in the working process of the motor 5; when the combustion gas bubble in aeration plate 2 floats, stirring leaf 3 striking bubble, the bubble rocks the molecule and does the random motion of never stopping this moment in the purifying liquid, consequently flying dust in the bubble, the coal dust, SO2, NOx, impurity such as CO can contact with the edge of bubble, the bubble moving path has been changed and the bubble receives the power of horizontal direction, thereby make the bubble can remove at the horizontal direction, the required time of bubble come-up has been prolonged, for the probability of impurity in the bubble with the contact of bubble lateral wall has been increased, for the contact probability of impurity and purifying liquid, thereby purifying effect has been improved.

When the exhaust gas is discharged from the aeration plate 2, solid impurities such as fly ash and coal dust in the exhaust gas are suspended in the purification liquid, and the impurities cannot be precipitated in the positive and negative rotation processes of the stirring blades 3, and in the upward moving process of the bubbles, the bubbles are attached to the surfaces of the impurities and drive the impurities to move upward together; during operation, the motor 5 drives the mounting pipe 10 to rotate, at this time, the mounting pipe 10 drives the first filter screen 12 to rotate through the mounting rod 11, during the rotation of the first filter screen 12, the purified liquid and the bubbles both pass through the first filter screen 12, the impurities are pushed by the first filter screen 12 and rotate along with the first filter screen 12, during the rotation of the impurities along with the first filter screen 12, the bubbles discharged from the aeration plate 2 still float upwards, and when the floating bubbles contact the impurities on the surface of the first filter screen 12, the impurities are pushed upwards by the bubbles, so the impurities move upwards along the side wall of the first filter screen 12 until moving into the guide groove 13 at the top end of the first filter screen 12, because the opening of the guide groove 13 faces downwards, and the mounting rod 11 is obliquely inserted on the mounting pipe 10, when the bubbles and the impurities enter the guide groove 13, the impurities in the guide groove 13 are pushed upwards by the bubbles and the pushing force in the direction of the guide groove 13, the bubbles drive the impurities to move along the guide groove 13 and enter the mounting pipe 10, after the bubbles and the impurities enter the inside of the mounting pipe 10, at this time, the impurities enter the filter barrel 10, the impurities in this time, the filter barrel 14, the impurities are pushed upwards by the bubbles and the filter barrel 14, so the impurities enter the filter barrel 14, the impurities continuously pass through the filter barrel 14, and the bubbles and the impurities in the filter barrel 14, the dust; therefore, the installation pipe 10 can clean solid impurities in the box body 1 in time in the rotating process, so that the bubbles are prevented from being attached to the surfaces of the impurities, namely, the contact area between the bubbles and the purifying liquid is increased, the effect of improving the purifying effect is achieved, meanwhile, the frequency of replacing the purifying liquid is reduced, and the effect of improving the working efficiency is achieved.

In the floating process of the small bubbles, the water pressure borne by the small bubbles is gradually reduced, the volume of the small bubbles is increased, and partial small bubbles are fused into large bubbles after being mutually contacted, so that the small bubbles are gradually changed into large bubbles in the floating process, and the content of harmful gas in the bubbles is unchanged, so that the probability of contact between impurities and the side walls of the bubbles is reduced after the volume of the bubbles is increased; in the process of large bubble floating, the first filter screen 12 rotating along with the installation pipe 10 impacts large bubbles, and the large bubbles pass through the first filter screen 12 and are cut into small bubbles by the first filter screen 12, so that the bubbles float in the form of small bubbles again, and the effect of ensuring that harmful gas in the bubbles can be in edge contact with the bubbles is achieved.

In the working process, the content of solid impurities in the purified liquid is gradually increased, so that the filter barrel 14 is gradually filled with the impurities, the solid impurities in the filter barrel 14 can be timely transferred in the waste gas treatment process through the cooperation of the water pump 17, the guide pipe 18, the collecting box 16 and the return pipe 21, the filter barrel 14 can be ensured to continuously collect the impurities, the content of the solid impurities in the purified liquid is reduced, and the purification effect is improved; and the operation of stopping the machine is not needed, so that the function of ensuring the working efficiency is achieved.

In the initial state, the elastic air bag 27 is in a normal state, the pneumatic telescopic rod 25 is in a contraction state at the time, the pressing plate 28 is in a horizontal state under the action of the supporting rod 29, the bottom wall of the pressing plate 28 is attached to the top wall of the supporting rod 29, the box body 1 and the collecting box 16 are in a separation state under the action of the electromagnetic valve 19, and the water pump 17 intermittently works in the waste gas purification process; when the water pump 17 works, the electromagnetic valve 19 is opened, at the same time, the water pump 17 absorbs the purified liquid from the transit box 9 through the water inlet pipe 20, so that the transit box 9 is in a negative pressure state, at the same time, the transit box 9 absorbs the liquid from the diversion trench 13 and the filter vat 14 through the installation pipe 10, so that the solid impurities in the filter vat 14 are sucked into the transit box 9 and then into the water pump 17 along with the purified liquid, thereby the solid impurities in the filter vat 14 can be transferred, and the filter vat 14 can be ensured to continuously collect the impurities; the water flow discharged from the water pump 17 flows in the conduit 18, and the water flow impacts the pressure plate 28 during the flow along the conduit 18 and then flows along the spiral pipe 26, when the pressure plate 28 rotates around the hinge point, the pressure plate 28 presses the elastic air bag 27 during the rotation of the pressure plate 28, when the air in the elastic air bag 27 enters the air telescopic rod 25, the output end of the air telescopic rod 25 extends upwards, the output end of the air telescopic rod 25 pushes the one-way valve 24 of the mounting plate 22 upwards to close, the air in the space above the mounting plate 22 in the collecting tank 16 enters the tank body 1 along the return pipe 21, the time required for the water flow in the conduit 18 to enter the collecting tank 16 is prolonged under the action of the spiral pipe 26, so that the water in the conduit 18 gradually flows into the collecting tank 16 when the mounting plate 22 moves to the top of the collecting tank 16; the space below the second filter screen 23 in the collection box 16 is gradually filled with the purified liquid containing solid impurities, when the collection box 16 is filled with the purified liquid, the water pump 17 is automatically powered off, at the moment, the purified liquid in the guide pipe 18 stops applying impact force to the pressure plate 28, at the moment, the pressure plate 28 cannot continuously transmit the impact force to the elastic air bag 27, and the elastic force of the elastic air bag 27 is greater than the gravity of the pressure plate 28, so that the elastic air bag 27 starts to restore, in the restoring process of the elastic air bag 27, the pneumatic telescopic rod 25 gradually contracts, in the process, the mounting plate 22 is not subjected to the upward thrust of the pneumatic telescopic rod 25 any more, so that the mounting plate 22 gradually moves downwards under the action of the gravity of the mounting plate 22, the one-way valve 24 is opened in the descending process of the mounting plate 22, and at the moment, the purified liquid in the space below the mounting plate 22 in the collection box 16 passes through the second filter screen 23 and the one-way valve 24 and enters the space above the mounting plate 22.

When the water pump 17 works again, the pneumatic telescopic rod 25 applies upward thrust to the mounting plate 22 again, the check valve 24 is in a closed state at the moment, and the purifying liquid in the space above the mounting plate 22 in the collecting box 16 is pushed upwards by the mounting plate 22, the purifying liquid enters the return pipe 21 and flows into the box body 1 along the return pipe 21 at the moment, so that the purifying liquid containing solid impurities can be filtered and re-injected into the box body 1 for use in the whole process, the automation degree is improved, the content of solid particles in the box body 1 is reduced at the same time, the contact area between bubbles and the purifying liquid is increased, the purifying effect is improved, and in comparison with the frequent addition of new purifying liquid, the resource saving effect is achieved.

During operation of the air pump, part of the air in the filter vat 14 is also sucked into the collecting chamber 16, and when the mounting plate 22 moves down along the collecting chamber 16, the air passes through the second screen 23 together with the cleaning liquid, during which the air is again divided into small bubbles and can come into contact with the cleaning liquid above the mounting plate 22, during which harmful gases in the small bubbles can be cleaned, thereby ensuring that clean air is discharged from the tank 1 when the air flows along the return pipe 21 into the tank 1.

The temperature of the exhaust gas discharged by the power plant is high, so that the temperature of the purifying liquid in the box body 1 can be gradually increased and the volatilization speed of the purifying liquid can be increased; the distance between the collection box 16 and the box body 1 is increased under the action of the mounting rack 15, so that when the purified liquid enters the collection box 16, the temperature of the purified liquid in the collection box 16 can be reduced, and when the purified liquid with lower temperature flows into the box body 1 along the return pipe 21, the purified liquid is at the top of the liquid level at low temperature, so that the volatilization speed of the purified liquid is reduced, and the effect of saving cost is achieved; the intermittent operation of the water pump 17 plays a role in saving electric energy, and in the operation process of the water pump 17, under the action of the spiral pipe 26, when the mounting plate 22 moves to the top end of the collecting box 16, the purifying liquid with higher temperature in the guide pipe 18 starts to flow into the collecting box 16, so that the purifying liquid with higher temperature is prevented from contacting with the low-temperature purifying liquid in the collecting box 16, and the effect of ensuring that the purifying liquid with low temperature flows into the box body 1 through the return pipe 21 is achieved.

Because the impact force of the water flow discharged from the water pump 17 is large, when the water flow enters the collection box 16, the impact force of the water flow is also large, when the water flow contacts the second filter screen 23, solid matters in the water flow are easily clamped on the second filter screen 23, and therefore the impact force of the water flow matched with the elastic air bag 27 through the pressing plate 28 is neutralized with the elastic force of the elastic air bag 27, so that the impact force of the water flow can be consumed, the impact force when the water flow enters the collection box 16 can be reduced, and the effect of preventing the solid impurities in the water flow from being blocked in the second filter screen 23 to block the second filter screen 23 is achieved.

s4, when the purifying liquid flows along the guide pipe 18, the mounting plate 22 moves upwards along the inner wall of the collecting box 16, and at the moment, the clean purifying liquid above the mounting plate 22 flows into the box body 1 along the return pipe 21, so that the clean purifying liquid can be recycled, when the water pump 17 stops working, the mounting plate 22 moves downwards along the inner wall of the collecting box 16, and at the moment, the purifying liquid containing solid impurities below the mounting plate 22 passes through the second filter screen 23 and enters the space above the mounting plate 22, so that the automatic filtering effect is realized.

The working principle is as follows: exhaust gas generated when fuel coal used in a power plant is burned contains impurities such as fly ash, coal dust, SO2, NOx, CO, etc., and is discharged to the air after the exhaust gas is purified in order to protect the environment, but when the exhaust gas is transported to a purification liquid through an aeration plate 2, dust such as fly ash and coal dust in the exhaust gas is suspended in the purification liquid, and bubbles are attached to the surface of the dust during the floating of the bubbles, SO that the contact area between the bubbles and the purification liquid is reduced, and thus the purification effect is deteriorated, and as the operation time increases, the dust content in the purification liquid gradually increases, and the contact area between the bubbles and the purification liquid is further reduced, SO that the purification liquid needs to be periodically replaced, SO that the workload of workers is increased, and the exhaust gas treatment work cannot be performed during the replacement of the purification liquid, and thus the purification efficiency is reduced; in order to improve the purification efficiency and purification effect, when purifying waste gas, firstly, the air inlet of the aeration plate 2 is communicated with the air outlet of the waste gas manufacturing device, then the motor 5 is started, at the moment, the motor 5 drives the second half gear 6 to rotate, when the gear teeth on the second half gear 6 are meshed with the gear teeth of the first half gear 4, the second half gear 6 drives the first half gear 4 to rotate so as to drive the stirring blades 3 to rotate forward and the clockwork spring 7 to accumulate force, when the gear teeth on the second half gear 6 are separated from the gear teeth of the second half gear 6, the clockwork spring 7 releases force and drives the stirring blades 3 to rotate reversely, so that the stirring blades 3 always rotate forward and backward in the working process of the motor 5; when the combustion gas bubble in aeration plate 2 floats, stirring leaf 3 striking bubble, the bubble rocks the molecule and does the random motion of never stopping this moment in the purifying liquid, consequently flying dust in the bubble, the coal dust, SO2, NOx, impurity such as CO can contact with the edge of bubble, the bubble moving path has been changed and the bubble receives the power of horizontal direction, thereby make the bubble can remove at the horizontal direction, the required time of bubble come-up has been prolonged, for the probability of impurity in the bubble with the contact of bubble lateral wall has been increased, for the contact probability of impurity and purifying liquid, thereby purifying effect has been improved.

When the water pump 17 works again, the pneumatic telescopic rod 25 applies upward thrust to the mounting plate 22 again, the check valve 24 is in a closed state at the moment, the purifying liquid in the space above the mounting plate 22 in the collecting box 16 is pushed upwards by the mounting plate 22, the purifying liquid enters the return pipe 21 and flows into the box body 1 along the return pipe 21 at the moment, so that the purifying liquid containing solid impurities can be filtered and injected into the box body 1 again in the whole process, the automation degree is improved, the content of solid particles in the box body 1 is reduced at the same time, the contact area between bubbles and the purifying liquid is increased, the purifying effect is improved, and the resource saving effect is achieved compared with the frequent addition of new purifying liquid.

During operation of the air pump, part of the air in the filter vat 14 is also sucked into the collection tank 16, and when the mounting plate 22 moves down along the collection tank 16, the air passes through the second screen 23 together with the cleaning liquid, during which the air is again divided into small bubbles and can come into contact with the cleaning liquid above the mounting plate 22, during which harmful gases in the small bubbles can be cleaned, thereby ensuring that clean air is discharged from the tank 1 when the air flows along the return pipe 21 into the tank 1.

The temperature of the exhaust gas discharged by the power plant is high, so that the temperature of the purifying liquid in the box body 1 can be gradually increased and the volatilization speed of the purifying liquid can be increased; the distance between the collection box 16 and the box body 1 is increased under the action of the mounting frame 15, so that when the purified liquid enters the collection box 16, the temperature of the purified liquid in the collection box 16 can be reduced, and when the purified liquid with lower temperature flows into the box body 1 along the return pipe 21, the purified liquid is at the top of the liquid level at low temperature, so that the volatilization speed of the purified liquid is reduced, and the effect of saving the cost is achieved; the intermittent operation of the water pump 17 plays a role in saving electric energy, and in the operation process of the water pump 17, under the action of the spiral pipe 26, when the mounting plate 22 moves to the top end of the collecting box 16, the purifying liquid with higher temperature in the guide pipe 18 starts to flow into the collecting box 16, so that the purifying liquid with higher temperature is prevented from contacting with the low-temperature purifying liquid in the collecting box 16, and the effect of ensuring that the purifying liquid with low temperature flows into the box body 1 through the return pipe 21 is achieved.

s3, the water pump (17) works regularly, and in the working process of the water pump (17), impurities in the filter barrel (14) are pumped out and discharged into the collection box (16) through the transfer box (9), the water inlet pipe (20) and the guide pipe (18) by the water pump (17), so that the filter barrel (14) can continuously collect the impurities, purified liquid does not need to be replaced frequently, and the working efficiency is improved;

s4, when the purifying liquid flows along the guide pipe (18), the mounting plate (22) moves upwards along the inner wall of the collecting box (16), at the moment, the clean purifying liquid above the mounting plate (22) flows into the box body (1) along the return pipe (21), so that the clean purifying liquid can be recycled, when the water pump (17) stops working, the mounting plate (22) moves downwards along the inner wall of the collecting box (16), at the moment, the purifying liquid containing solid impurities below the mounting plate (22) passes through the second filter screen (23) to enter a space above the mounting plate (22), and therefore the automatic filtering effect is achieved.
