Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

With the development of modern industry, the influence of dust on the environmental pollution and the human health is increasingly serious, and the control of dust pollution and the purification of human living environment become common knowledge of people in China.

The equipment for separating dust from flue gas is called dust remover or dust removing equipment. The performance of a precipitator is expressed in terms of the amount of gas that can be treated, the resistance loss of the gas as it passes through the precipitator, and the efficiency of the precipitation. Meanwhile, the price, the operation and maintenance cost, the service life and the difficulty of operation management of the dust remover are also important factors considering the performance of the dust remover. The dust remover has various types, including a sintered plate dust remover, a pulse bag type dust remover and the like, wherein the pulse bag type dust remover has the advantages of high adaptability, high dust collection efficiency, reasonable structure, remarkable energy-saving effect and the like.

The dust remover is widely applied to grain conveying and processing enterprises; dust collecting systems of crushing, packaging, warehouse top, clinker cooler, various mills and the like in cement plants are also applied to dust collection of waste gases of metallurgy, chemical industry, machinery, civil boilers and the like. However, the existing dust remover is easy to block the filter bag in the dust removing process, so that the dust removing effect of the dust remover is reduced. In general, dust cleaning treatment is performed on a filter bag of a dust collector at regular time in order to prevent the filter bag of the dust collector from being blocked by dust. However, because the dust suction port and the dust outlet of some dust collectors (such as plug-in dust collectors) are the same opening, when the dust collector ejects a positive pressure airflow for cleaning the filter bag, the negative pressure airflow generated in the dust collector for dust suction still works, and the positive pressure airflow and the negative pressure airflow counteract each other, so that the positive pressure airflow cannot clean the dust on the filter bag, that is, the cleaning rate of the filter bag in the dust collector is low.

Based on the above analysis, the embodiment of the present application provides a dust remover 10 and a dust removing system, wherein a first valve 132 is disposed in a dust suction module 130 in the dust remover 10, and when the dust remover 10 is in normal operation for removing dust, the first valve 132 can be opened, so that dust can be sucked out of the machine body 110 of the dust remover 10 from the first valve 132 by an airflow to be removed generated by the fan 131; when the back-flushing dust-cleaning module 140 in the dust collector 10 cleans the filter bag 120, the first valve 132 may be closed, and the fan 131 cannot generate the airflow to be cleaned any more, so that the back-flushing dust-cleaning module 140 may blow off the dust on the filter bag 120 in the dust collector 10, and the dust-cleaning airflow generated by the back-flushing dust-cleaning module 140 may not be offset by the airflow to be cleaned generated by the fan 131, thereby improving the cleaning rate of the filter bag 120 in the dust collector 10.

The dust separator 10 provided in the embodiment of the present application will be described in detail below.

Referring to fig. 1, fig. 1 is a block diagram of a dust remover according to an embodiment of the present disclosure, where the dust remover 10 may include: the machine body 110, the filter bag 120, the dust suction module 130, the back-flushing deashing module 140 and the control module 150. Wherein, the filter bag 120 is disposed in the body 110; the dust suction module 130 is disposed in the machine body 110, and the dust suction module 130 includes a fan 131 and a first valve 132, the first valve 132 is disposed at one side of the fan 131; the back-blowing ash-cleaning module 140 is arranged at one side of the filter bag 120; the control module 150 is connected with the dust suction module 130 and the blowback ash removal module 140. When the first valve 132 is opened, the airflow to be dedusted is dedusted by the filter bag 120 and sucked out of the machine body 110 from the first valve 132 by the fan 131; when the first valve 132 is closed, the back-flushing ash-cleaning module 140 cleans the filter bag 120.

For example, the dust collector 10 provided by the embodiment of the present application may include a body 110, where the body 110 corresponds to an air chamber of the dust collector 10, and encloses the nozzle 141 and the filter bag 120 of the dust collector 10 therein, so as to perform the functions of separating the dust airflow, cleaning the airflow, protecting the components, and preventing moisture and water.

It can be understood that, since the dust remover 10 needs to suck the airflow to be removed carrying the dust flying in the air, then filter the airflow to be removed to obtain the dust mass and the clean airflow, then discharge the clean airflow out of the dust remover 10, and return the collected dust mass to the conveying line through the dust backflow to be mixed with the material. Therefore, the body 110 of the dust collector 10 may be provided with two openings, one opening is used for sucking the airflow to be collected (named as a first opening), and the other opening is used for discharging the cleaned airflow obtained after the airflow to be collected is filtered (named as a second opening). In the embodiment of the present application, the position, shape, and size of the opening formed in the body 110 are not specifically limited, and those skilled in the art can appropriately adjust the opening according to actual situations.

It should be noted that the shape and material of the body 110 are not limited in the embodiments of the present application, and those skilled in the art can adopt the body 110 with a suitable shape and material by combining with the conventional technical means in the field.

In the above-mentioned body 110, one or more filter bags 120 may be provided, and the filter bags 120 function to filter the airflow to be dedusted sucked into the deduster 10 to remove dust therefrom. The air flow to be dedusted filtered by the filter bag 120 can be regarded as a clean air flow and a dust mass. The dust group can be returned to the conveying line to save raw materials; the clean airflow may be exhausted from the precipitator 10 back into the ambient air to effect precipitation of the ambient air.

It should be noted that, in the embodiment of the present application, the number, the type, the shape, the arrangement, and the like of the filter bags 120 are not specifically limited, and those skilled in the art can adopt the appropriate filter bags 120 by combining with the conventional technical means in the art.

In the above description, the airflow to be cleaned may be drawn into the dust collector 10, and then the cleaned airflow filtered by the airflow to be cleaned may be discharged from the dust collector 10, and it is the dust collection module 130 in the dust collector 10 that performs the process. As an embodiment, the dust suction module 130 may include a blower 131 and a first valve 132. The fan 131 may be disposed outside the body 110 of the dust collector 10 at a second opening for discharging the clean air flow obtained by filtering the air flow to be dedusted, and is used for sucking the air flow to be dedusted into the dust collector 10 and sucking the clean air flow obtained by filtering the air flow to be dedusted out of the body 110 of the dust collector 10 through the second opening. The first valve 132 may also be disposed at the second opening, that is, may be disposed between the fan 131 and the second opening (the fan 131-the first valve 132-the second opening), or may be disposed in the order of the first valve 132-the fan 131-the second opening, which is not specifically limited in this embodiment of the present application. As an embodiment, the first valve 132 may be a pneumatic valve, a valve driven by compressed air.

When the first valve 132 is opened, the fan 131 can suck the airflow to be dedusted into the deduster 10 and suck the cleaning airflow out of the deduster 10 body 110 through the second opening; when the first valve 132 is closed, the fan 131 cannot draw the airflow to be cleaned into the dust collector 10 and draw the cleaning airflow out of the body 110 of the dust collector 10 through the second opening, in other words, the fan 131 cannot generate the airflow from the first opening to the second opening inside the dust collector 10.

After the dust collector 10 is used for a period of time, a large amount of dust is deposited on the filter bag 120 arranged inside the machine body 110, which affects the normal dust collection of the dust collector 10. Therefore, the filter bag 120 can be subjected to ash removal, and the process is performed by the blowback ash removal module 140 in the dust collector 10. The reverse blowing ash removal module 140 can generate ash removal air flow to blow off the deposited ash on the filter bag 120, and also form dust clusters to return to the material conveying line. If the back-blowing dust-cleaning module 140 and the dust-absorbing module 130 work simultaneously, the dust-cleaning airflow and the airflow to be dedusted are offset, so that the dust-cleaning effect of the filter bag 120 is greatly reduced, and meanwhile, the dust cleaned from the filter bag 120 is not mixed with the material and is sucked onto the filter bag 120. Therefore, there is a problem in that the cleaning rate of the filter bag 120 in the dust collector 10 is low.

Therefore, when the blowback ash removal module 140 is operated, the operation of the dust collection module 130 can be stopped by closing the first valve 132. After the first valve 132 is closed, the fan 131 cannot generate an airflow from the first opening to the second opening inside the dust collector 10, so that only an ash cleaning airflow capable of cleaning the filter bag 120 exists inside the dust collector 10, the ash cleaning airflow can efficiently clean the ash deposited on the filter bag 120, and the cleaning opportunity can be avoided to return to the filter bag 120 again. That is, by closing the first valve 132 when the blowback ash removal module 140 is in operation, the cleaning rate of the filter bag 120 in the dust collector 10 can be increased.

It can be understood that the first valve 132 is not necessarily closed every time the back-flushing ash-cleaning module 140 works, and only a period of time is needed to ensure that the first valve 132 is in a closed state when the back-flushing ash-cleaning module 140 works once.

Referring to fig. 2 as an implementation manner, fig. 2 is a block diagram of another dust remover provided in the embodiment of the present application, and in the dust remover 10, the blowback ash removal module 140 may include a spray pipe 141 and a second valve 142. The nozzle 141 may be disposed in the body 110 of the dust collector 10, and the nozzle 141 may have one or more air outlets, each of which faces the corresponding filter bag 120 and is used for spraying the ash removal air flow onto the filter bag 120. The position, the size and the like of the air hole are not specifically limited, and the person skilled in the art can adjust the air hole appropriately according to actual conditions. For example: one air hole corresponds to one filter bag 120, and each air hole is arranged at equal intervals.

The second valve 142 may be disposed at one end of the nozzle 141, and the second valve 142 may be a pulse solenoid valve as an embodiment. The pulse electromagnetic valve is realized according to the following principle; the coil in the pulse electromagnetic valve body is input with a pulse signal through a wire, the pulse electromagnetic valve is controlled by an output signal of a pulse injection control instrument, and the rubber diaphragm is enabled to be bent and deformed to open and close the pulse electromagnetic valve by means of pressure changes of the front air chamber and the rear air chamber of the valve. The number of the second valves 142 is not specifically limited in the embodiment of the present application, and may be one second valve 142, multiple second valves 142, or the number of the second valves 142 corresponds to the number of the filter bags 120. When the number of the second valves 142 is equal to the number of the filter bags 120, the reverse-blowing ash-cleaning module 140 can respectively clean the ash of the different filter bags 120 by controlling the opening and closing of the different second valves 142.

When the second valve 142 is opened, the nozzle 141 can spray the ash removal airflow onto the filter bag 120, so that the ash removal airflow blows off the integral on the filter bag 120, and the ash removal effect on the filter bag 120 is achieved; when the second valve 142 is closed, the nozzle 141 cannot spray the flow of ash cleaning gas onto the filter bag 120. With reference to the first valve 132 in the above embodiment, when the first valve 132 is closed and the second valve 142 is opened, only the ash cleaning airflow capable of cleaning the filter bag 120 exists inside the dust collector 10, and the ash cleaning airflow can effectively clean the ash deposited on the filter bag 120 and prevent the cleaning opportunity from returning to the filter bag 120.

It can be understood that the second valve 142 can be opened when the dust removing module 140 needs to be blown back to remove dust from the filter bag 120, or can be opened periodically, and only in a period of time, the second valve 142 is in an open state when the dust removing module 130 stops working.

Therefore, the dust suction module 130 in the dust collector 10 is provided with the first valve 132, and when the dust collector 10 is in normal operation for dust removal, the first valve 132 can be opened, so that the clean airflow obtained by filtering the airflow to be removed can be sucked out of the machine body 110 of the dust collector 10 from the first valve 132 by the fan 131; when the back-flushing deashing module 140 in the dust collector 10 is to perform deashing on the filter bag 120, the first valve 132 can be closed. The second valve 142 is arranged in the blowback ash removal module 140 in the dust remover 10, and when the blowback ash removal module 140 in the dust remover 10 needs to perform ash removal on the filter bag 120, the second valve 142 can be opened, so that dust can be blown off from the filter bag 120 by the ash removal airflow generated by the spray pipe 141; the second valve 142 may be closed when the duster 10 is operating normally for dusting. When the first valve 132 is closed and the second valve 142 is opened, the fan 131 cannot suck the cleaning air flow out of the dust collector 10, so that the back-blowing ash-cleaning module 140 can blow off the dust on the filter bag 120 in the dust collector 10, and the ash-cleaning air flow generated by the back-blowing ash-cleaning module 140 cannot be offset by the cleaning air flow sucked out by the fan 131, thereby improving the cleaning rate of the filter bag 120 in the dust collector 10.

In addition, the dust collector 10 provided in the embodiment of the application may further include a control module 150, where the control module 150 is connected to the dust collection module 130 and the back-blowing ash removal module 140, and respectively controls the dust collection module 130 to collect dust and the back-blowing ash removal module 140 to remove ash from the filter bag 120. It is understood that when the dust module 130 includes the first valve 132, the control module 150 may be connected to the first valve 132 to control the opening and closing of the first valve 132; when the first valve 132 is a pneumatic valve, the control module 150 is connected to the coil of the pneumatic valve. Similarly, when the blowback ash removal module 140 includes the second valve 142, the control module 150 can be connected to the second valve 142 to control the opening and closing of the second valve 142; when the second valve 142 is a pulsed solenoid valve, the control module 150 is connected to the coil of the pulsed solenoid valve.

As an embodiment, the process of controlling the dust collection module 130 to collect dust and the process of cleaning the filter bags 120 by the blowback dust-cleaning module 140 by the control module 150 may be manually controlled by an operator. For example: when the dust remover 10 needs to be started for removing dust, an operator can input a corresponding instruction to the control module 150, turn on the fan 131, and the control module 150 outputs a control instruction to open the first valve 132 and close the second valve 142; when the dust in the filter bag 120 needs to be cleaned, the operator can input a corresponding command to the control module 150 again, and the control module 150 outputs a control command to open the second valve 142 and close the first valve 132.

It is understood that the above manual control process is only an example provided by the embodiments of the present application, and those skilled in the art can make suitable adjustments according to actual situations to achieve the dust removal of air and the dust removal of the filter bag 120 in the dust remover 10.

As another embodiment, the process of controlling the dust collection module 130 to collect dust and the process of performing dust cleaning on the filter bag 120 by the blowback dust cleaning module 140 by the control module 150 may be controlled by an existing program, and at this time, referring to fig. 2, the control module 150 may further include a single chip microcomputer controller, and the single chip microcomputer controller is connected to the dust collection module 130 and the blowback dust cleaning module 140. Wherein, the function of the control module 150 can be realized on the above-mentioned single-chip computer controller by those skilled in the art in combination with common knowledge. A control process for performing dust removal on the dust removal module 130 and performing dust removal on the filter bag 120 by the back-flushing dust removal module 140 is described in detail below.

Take the example that the dust collector 10 includes 13 filter bags 120, and each filter bag 120 corresponds to one second valve 142, that is, the dust collector 10 further includes 13 second valves 142. In the embodiment of the present invention, each second valve 142 may be opened in turn at preset time intervals, and in order to reduce the frequency of the operation of the first valve 132, the embodiment of the present invention uses the mode of closing the first valve 132 at intervals. That is, not every time the blowback ash is performed, the first valve 132 is closed and all of the second valves 142 are opened. Because the generation amount of the compressed air is limited, the second valves 142 can be opened in turn to generate the ash removal airflow, and the ash removal is performed on one filter bag 120 each time, and all the filter bags 120 are subjected to back flushing once to form a period.

As an embodiment, each cycle only closes the first valve 132 when about one third of the filter bags 120 are back-blown, and does not close the first valve 132 when the rest of the filter bags 120 are back-blown. Referring to fig. 3, fig. 3 is a timing chart for controlling the first valve and the second valve according to an embodiment of the present application, and it can be seen from fig. 3 that two pulses for opening the second valve 142 correspond to one operation for closing the first valve 132. For example: in the first period, the first valve 132 may be closed when the pulse peak value V3 corresponding to the third second valve, the pulse peak value V6 corresponding to the sixth second valve, the pulse peak value V9 corresponding to the ninth second valve, and the pulse peak value V12 corresponding to the twelfth second valve, respectively; in the second period, the first valve 132 is closed when the pulse peak value V2 corresponding to the second valve, the pulse peak value V5 corresponding to the fifth valve, the pulse peak value V8 corresponding to the eighth valve and the pulse peak value V11 corresponding to the eleventh valve are respectively closed; in the third period, the first valve is closed when the pulse peak value V1 corresponding to the first second valve, the pulse peak value V4 corresponding to the fourth second valve, the pulse peak value V7 corresponding to the seventh second valve, the pulse peak value V10 corresponding to the tenth second valve and the pulse peak value V13 corresponding to the thirteenth second valve are respectively. After the three cycles, the ash removal treatment of all the filter bags 120 is completed.

In this embodiment, the single-chip microcomputer in the control module 150 can control the dust-collecting module 130 and the back-blowing ash-cleaning module 140, so that the dust collector 10 can collect dust and clean the filter bag 120.

Further, the dust collector 10 may further include a power module 160, and the power module 160 is connected to the dust collection module 130, the control module 150, and the blowback ash removal module 140.

The following description will discuss a dust separator 10 according to an embodiment of the present application by way of example. Referring to fig. 4, fig. 4 is a schematic structural diagram of a dust collector provided in the embodiment of the present application, in which the dust collector 10 includes a body 110, a filter bag 120, a fan 131, a first valve 132, a spray pipe 141, a second valve 142, and a control module 150. The filter bag 120 is disposed in the machine body 110, and divides the machine body 110 into an upper air chamber and a lower air chamber, a fan 131, a first valve 132, a nozzle 141, a second valve 142, and a control module 150, wherein the fan 131 is disposed in the upper air chamber, the first valve 132 is disposed at an outlet of the fan 131, the nozzle 141 is connected to the second valve 142, and the control module 150 is connected to the first valve 132 and the second valve 142. The implementation of the dust remover 10 in the embodiment of the present application is similar to that in the above embodiments, and the description thereof is omitted here.

Based on the dust remover 10 provided in the foregoing embodiment, an embodiment of the present application further provides a dust removing system, please refer to fig. 5, where fig. 5 is a block diagram of a structure of the dust removing system provided in the embodiment of the present application, and the dust removing system may include: the dust remover 10 and the air storage tank 20, the air storage tank 20 is connected with the back-blowing ash-cleaning module 140 in the dust remover 10.

Specifically, the compressed air is stored in the air storage tank 20, the second valve 142 in the blowback ash removal module 140 may be installed on an air path of the compressed air, and at the moment when the second valve 142 is opened, the compressed air in the air storage tank 20 is instantaneously released to form a high-pressure pulse airflow, which is ejected from the air injection hole of the injection pipe 141 in the blowback ash removal module 140 to the filter bag 120, so as to achieve the ash removal effect on the filter bag 120.

Further, referring to fig. 5, the dust removing system may further include: and the air compressor 30 is connected with the air storage tank 20, and the air compressor 30 is connected with the air storage tank 20.
