In a second aspect of the present disclosure, there is provided a dust removing method, which may be applied to the dust removing system mentioned in all the above-mentioned embodiments, as shown with reference to fig. 3, the dust removing method including:
s1, monitoring the dust concentration and the water mist concentration in the transportation chamber 3 through a monitoring mechanism 4;
s2, controlling the dust settling device 5 to remove dust from the inlet of the conveying chamber 3, the outlet of the conveying chamber 3 and the inside of the conveying chamber 3 according to the dust concentration and the water mist concentration.
Through the method, the monitoring mechanism 4 can monitor the dust concentration and the water mist concentration in the transportation chamber 3 in real time, and can properly adjust the dust removal force of the dust removal device 5 on the transportation chamber 3 according to the difference of the dust concentration and the water mist concentration under different working conditions so as to achieve better dust removal effect.
In some embodiments, the dust-settling device 5 comprises a charged fog gun assembly capable of dedusting the inlet of the transport chamber 3, the outlet of the transport chamber 3, and a water mist dedusting assembly capable of dedusting the interior of the transport chamber 3; in the step of controlling the dust settling device 5 to settle dust on the inlet of the transport chamber 3, the outlet of the transport chamber 3 and the inside of the transport chamber 3 in accordance with the dust concentration and the water mist concentration, it comprises:
when the dust concentration meets a first preset value, the first dust removal parameter of the charged fog gun assembly 510 and the second dust removal parameter of the water fog dust removal assembly are adjusted, and the charged fog gun assembly 510 and the water fog dust removal assembly are controlled to remove dust from the inlet of the transportation chamber 3, the outlet of the transportation chamber 3 and the inside of the transportation chamber 3;
when the water mist concentration meets a second preset value, the second dust removal parameter of the water mist dust removal assembly is adjusted, and the water mist dust removal assembly is controlled to remove dust from the transportation chamber 3.
Through the above two steps, the first preset value may include an upper limit of a dust concentration set value inside the transportation chamber 3 and an upper limit of a dust concentration set value of an inlet and an outlet of the transportation chamber 3, when the dust concentration breaks through the upper limit, the charged fog gun assembly 510 may be controlled to remove dust from the inlet, the outlet and the inside of the transportation chamber 3, and the second preset value may include a lower limit of a water mist concentration value inside the transportation chamber 3, and when the water mist concentration is lower than the lower limit, the water mist dust removal assembly may be controlled to remove dust from the transportation chamber 3.
In some other embodiments, in the step of controlling the dust settling device 5 to settle dust on the inlet of the transporting chamber 3, the outlet of the transporting chamber 3 and the inside of the transporting chamber 3 according to the dust concentration and the water mist concentration, the following steps are mainly included:
when the monitoring mechanism 4 monitors the inlet of the transportation chamber 3, the outlet of the transportation chamber 3 and the dust concentration in the transportation chamber 3 are higher than the upper limit of the set value, the dust removing effect of the dust removing device 5 in the transportation chamber 3 is improved. In this step, the monitoring mechanism 4 monitors that the dust concentration of the transportation chamber 3 is higher than the upper limit of the set value, that is, the dust concentration is too high, and the transportation chamber 3 needs to be dedusted, so that the dedusting strength of the dust settling device 5 can be improved, and the dust concentration can be reduced.
When the monitoring mechanism 4 monitors the inlet of the transportation chamber 3, the outlet of the transportation chamber 3 and the dust concentration in the transportation chamber 3 are lower than the lower limit of the set value, the dust removing effect of the dust removing device 5 on the transportation chamber 3 is reduced. In this step, the monitoring mechanism 4 monitors that the dust concentration of the transportation chamber 3 is lower than the lower limit of the set value, that is, it means that the dust is eliminated by the dust-settling device 5 in step S21, at this time, the dust-settling force of the dust-settling device 5 can be slightly reduced, the dust-settling device 5 can be kept in a working state and operated at a low frequency all the time, and further, the dust-settling operation can be carried out all the time in the transportation process of the coal, so that dust removal can be realized, and low-energy operation of the dust-settling device 5 can be realized.
When the monitoring mechanism 4 monitors that the concentration of the water mist in the transportation chamber 3 is higher than the upper limit of the set value, the dust removing effect of the dust removing device 5 is reduced. In this step, when the concentration of the water mist in the transporting chamber 3 monitored by the monitoring mechanism 4 is higher than the upper limit of the set value, that is, the charged fog gun assembly 510 sprays too much water mist in the transporting chamber 3, in order to prevent the too much water mist and reduce the heating value of the transported coal, the dust removing force of the dust removing device 5 can be slightly reduced, the spraying amount of the water mist in the charged fog gun assembly 510 is reduced, and further, the coal is ensured not to be wetted due to too much sprayed water mist, and the heating value of the coal is reduced.
When the monitoring mechanism 4 monitors that the concentration of the water mist in the transportation chamber 3 is lower than the lower limit of the set value, the dust removing effect of the dust removing device 5 is improved. In this step, when the concentration of the water mist in the transporting chamber 3 monitored by the monitoring mechanism 4 is lower than the lower limit of the set value, the water mist representing the spraying of the charged fog gun assembly 510 in the transporting chamber 3 is too little, that is, the dust concentration in the transporting chamber 3 is also higher, at this time, the dust removing force of the dust removing device 5 can be increased, the spraying amount of the water mist in the charged fog gun assembly 510 is increased, and then a better dust removing effect is achieved.
In addition, it should be noted that the set value may be set to a corresponding suitable value according to different working conditions of the dust removal system, which is not specifically limited in the disclosure.
Referring to fig. 1, the dust removal system of the present disclosure operates on the principle that: when the coal is required to be transported, the coal can be placed on the first conveyor 1, and when the coal runs along with the first conveyor 1, the coal passes through the discharge end 101, the conveying pipeline 310, the feeding end 201, the second conveyor 2, the dust curtains 321 and the double-fluid spray heads 520 in sequence, and finally is discharged from the tail of the second conveyor 2, in the transportation process, before the coal enters the discharge end 101, the charged fog gun assembly 510 at the discharge end 101 can perform primary spraying on the coal to reduce dust, when the coal enters the conveying pipeline 310, the double-fluid spray heads 520 in the conveying pipeline 310 also perform spraying on the coal, when the coal enters the second conveyor 2 through the feeding end 201, the dust curtains 321 and the double-fluid spray heads 520 perform spraying on the coal, and when the coal is finally discharged from the tail of the second conveyor 2, the charged fog gun assembly 510 at the tail of the second conveyor 2 performs final spraying dust fall on the coal, so as to finish the whole dust fall process.
It should be noted that, in the process of the above-mentioned coal transporting and dust falling flow, the dust detector 410 located at the feeding end 201 and the discharging end 101 may detect the dust concentration of the environment where the coal is located, when the dust concentration is too high, the dust removing force of the charged fog gun assembly 510 and the water mist dust removing assembly may be improved, when the dust concentration is reduced, the dust removing force of the charged fog gun assembly 510 and the water mist dust removing assembly may be reduced, and likewise, the water mist monitor 420 located in the conveying pipeline 310 may monitor the water mist concentration in the conveying chamber 3, when the water mist concentration is too high, the spray amount of the water mist dust removing assembly may be reduced, when the water mist concentration is reduced, the spray amount of the water mist dust removing assembly may be increased, and further the dust removing force may be improved.
