Generally, pig centralized breeding can realize centralization and scale of pig breeding, and is convenient for unified management and breeding. The control method of the flushing system 100 and the flushing system 100 of the embodiment of the invention can prompt the state of the filtering equipment 120 in time, dredge the filtering equipment 120 in time, prevent the filtering equipment 120 from being blocked, and are beneficial to improving the efficiency of waste gas treatment.

In the example of fig. 2, the breeding building 200 includes 13 breeding houses 210. The middle position of the breeding building 200 is provided with a vertical waste gas channel 260, the waste gas channel 260 is communicated with each layer of breeding house 210 and a waste gas treatment chamber 270 positioned on the roof, waste gas of the breeding house can enter the waste gas treatment chamber 270 through the waste gas channel 260, and waste gas treated by the waste gas treatment chamber 270 can be discharged to the outside through an exhaust channel 280 communicated with the waste gas treatment chamber 270.

Specifically, each of the cultivation houses 210 is distributed on both sides of the exhaust passage 260. An air inlet 230 is formed in the outer wall 220 of the building. The air inlet 230 is provided with a cooling wet curtain 240, and outdoor air can enter the first air channel 231 through the cooling wet curtain 240 arranged on the air inlet 230, so that the effects of dust removal and cooling are achieved.

The first air channel 231 is defined by the outer wall 220 and the first partition 232, the first partition 232 is provided with an air filter 233, and the air filter 233 can filter air entering from the air inlet 230, so that the air quality breathed by the pigs in the breeding house 210 is better.

The second air passageway 234 is defined by the first partition 232 and the interior wall 235 of the habitat 210. The floor 236 of the farm house 210 spaces the farm house 210 from a third air channel 237, the third air channel 237 communicating with the second air channel 234, air being able to enter the third air channel 237 through the second air channel 234. A plurality of ventilation holes (not shown) may be formed in the floor 236, and the air in the third air passage 237 may be introduced into the breeding house 210 through the ventilation holes.

The air outlet of the air conditioner 250 is communicated with the breeding house 210. Specifically, the air conditioner 250 may be disposed on the second air channel 234, and the air outlet of the air conditioner 250 may be communicated with the breeding house 210 through the third air channel 237 and the air vent, as shown in fig. 3. Of course, the air conditioner 250 may be disposed in the first air passage 231, and the air conditioner 250 may be disposed in the breeding house 210. The specific location of the air conditioner 250 is not limited herein.

In the case where the air conditioner 250 is disposed in the breeding house 210, the air conditioner 250 may be protected by painting, filtering, and disposing a protective cover. It will be appreciated that the exhaust air in the breeding house 210 is somewhat corrosive, which may cause the air conditioner 250 to be corroded and damaged.

In one example, the air conditioner 250 is painted such that the paint layer separates the exhaust air from the air conditioner 250, thereby preventing damage to the air conditioner 250.

In another example, a filter is disposed in the air conditioner 250, so that the exhaust gas in the breeding house 210 is treated after entering the air conditioner 250, and the treated exhaust gas is discharged from the air conditioner 250 to enter the breeding house 210, thereby improving the air quality of the breeding house 210 and further avoiding the damage of the air conditioner 250.

In yet another example, a protective cover may be used to cover the air conditioner 250 when the air conditioner 250 is turned off to separate exhaust air from the air conditioner 250, thereby preventing damage to the air conditioner 250.

An air outlet 261 communicated with the waste gas channel 260 is formed in one side, close to the waste gas channel 260, of the breeding house 210, the air outlet 261 is provided with a shutter 238, air in the breeding house 210 can enter the waste gas channel 260 through the shutter 238, and then enters the waste gas treatment chamber 270, and finally is discharged to the outside from the exhaust channel 280.

Specifically, louvers 238 may open and close automatically due to the influence of air flow. Of course, the opening and closing of the louver 238 may be controlled by a motor. The specific form of opening and closing of the louvers 238 is not limited herein.

The fan 102 may be disposed in the exhaust gas treatment chamber 270, and the fan 102 may form a negative pressure in the exhaust gas channel 260, so that air enters the breeding house 210 from the air inlet 230 through the cooling wet curtain 240, the first air channel 231, the air filter 233, the second air channel 234, the third air channel 237 and the ventilation hole for the pigs to breathe, and exhaust gas generated by the pigs breathing is discharged to the outside from the breeding house 210 through the louvers 238, the exhaust gas channel 260, the exhaust gas treatment chamber 270 and the exhaust gas channel 280. The number of the fans 102 is specifically set according to actual conditions, for example, the number of the fans 102 is two or more, and the fans are arranged in the exhaust gas treatment chamber 270 side by side. Multiple fans 102 may be provided at different locations, for example, some or all of the fans 102 may be provided in the exhaust treatment chamber 270, some or all of the fans 102 may be provided in the exhaust passage 260, or other locations. The number of fans 102 may also be single. The fan 102 may be an axial fan.

It will be appreciated that by continuously supplying fresh air to the housing 210 and by removing exhaust air from the housing 210, the housing 210 can be kept ventilated, thereby providing a suitable growing environment for the pigs.

In an embodiment of the present invention, the filtration apparatus 120 includes a filtration wet curtain 122. It can be appreciated that the wet filter curtain 122 is air permeable and corrosion resistant, has excellent filtering effect on dust in the air, and can be used as a medium for air purification and filtration.

Specifically, the wet filter screen 122 may be a paper porous screen, which may be processed from base paper. Further, the wet filter curtain 122 may be honeycomb-shaped. When the exhaust gas passes through the surface of the porous and wet filtering wet curtain 122, the dirt carried by the exhaust gas is intercepted by the filtering wet curtain 122, and part of the gas in the exhaust gas can be dissolved in the wet liquid of the filtering wet curtain 122, so that the treatment of the exhaust gas is realized. The wet liquid of the filtering wet curtain 122 may be water, or may be a treatment liquid for treating the exhaust gas. When the pig enters the pigsty, the filtering wet curtain 122 is opened, and wet liquid is sprayed from the top of the filtering wet curtain 122, so that the filtering wet curtain 122 filters the waste gas.

In the embodiment of the present invention, the number of the wet filter curtains 122 is 3, and 3 wet filter curtains 122 are sequentially disposed in the exhaust gas treatment chamber 270 in the flow direction of the exhaust gas, as shown in fig. 2. It is understood that the number of wet filter curtains 122 may also be 2, 4, 5, 8, or other numbers. The specific number of wet filter curtains 122 is not limited herein.

In addition, in the exhaust gas treatment chamber 270, a pressure sensor 123 may be provided, and the pressure sensor 123 may be provided on the air outlet side of the filter device 120. In step S11, the outlet air pressure of the air outlet side of the filtering device 120 may be obtained by the pressure sensor 123.

In step S101, the prompting device 103 includes, but is not limited to, a warning light, a warning bell, a display screen, a speaker, a vibration motor, and the like. In one example, the preset pressure threshold is 65pa, and the outlet pressure of the air outlet side of the filter device 120 is 55pa, which is smaller than the preset pressure threshold, and at this time, the speaker can be controlled to broadcast: "Please note, filter equipment blocked" speech. In this example, the worker may manually clean or replace the filter device 120 after receiving the alarm message.

Referring to fig. 5, in some embodiments, the control method includes:

step S12: acquiring the air inlet pressure of the air inlet side of the filtering device 120;

step S13: and determining a preset pressure threshold according to the air inlet pressure.

In some embodiments, the obtaining module 11 is configured to obtain an intake air pressure on an intake side of the filtering device 120; the control module 14 is configured to determine a preset pressure threshold according to the intake air pressure.

In this way, a determination of the preset pressure threshold is achieved. It will be appreciated that the effect of the filter device 120 on the pressure of the exhaust gas filtered therethrough is known in advance. Therefore, the preset pressure threshold value for comparison with the outlet air pressure of the filter device 120 at the outlet side can be determined according to the inlet air pressure of the filter device 120 at the inlet side. Further, the effect of the filtering device 120 on the pressure of the exhaust gas filtered therethrough may be determined experimentally.

For example, the pressure of the inlet air on the inlet side of the filter device 120 is 100Pa (pa). Since the filter device 120 reduces the outlet air pressure to 80pa at the inlet air pressure of 100pa, the preset pressure threshold is set to 65 pa. The air outlet pressure of the air outlet side of the filtering device 120 is measured to be 60pa and is smaller than the preset pressure threshold, so that the control prompting device 103 prompts alarm information.

Note that, in the example of fig. 5, step S12 and step S13 follow step S11. It is understood that steps S12 and S13 may precede step S11 or be performed simultaneously with step S101. Fig. 5 is an example only, and does not represent a limitation on the order of step S12, step S13, and step S11.

In addition, in the example of fig. 2, the number of the filtering devices 120 is 3, and the preset pressure threshold corresponding to each filtering device 120 may be determined according to the intake air pressure on the intake air side of the filtering device 120. Further, the outlet pressure of the previous filtering device 120 may be used as the inlet pressure of the next filtering device 120.

For example, the pressure detected by the pressure sensor 123 at the air outlet side of the rightmost filtering device 120 in the 3 filtering devices 120 may be used as the air outlet pressure of the rightmost filtering device 120, or may be used as the air inlet pressure of the middle filtering device 120, so as to determine the preset pressure threshold corresponding to the middle filtering device 120 according to the air inlet pressure of the middle filtering device 120.

Further, note that a preset pressure threshold may be associated with the blower 102. Specifically, when the number of the fans 102 is one, the rotation speed of the fans 102 may have a corresponding relationship with a preset pressure threshold. In this way, whether the filtering device 120 is blocked can be more accurately judged, so that the prompting device 103 can be more accurately controlled to give an alarm.

It is understood that, in a normal state, the higher the rotation speed of the fan 102, the greater the outlet air pressure of the filtering device 120, and accordingly, the preset pressure threshold should be set to a larger value. Otherwise, the situation that the outlet air pressure is smaller than the preset pressure threshold even if the filtering device 120 is not blocked due to the low rotation speed of the fan 102 may occur, so as to cause misjudgment on whether the filtering device 120 is blocked and whether an alarm needs to be given.

Similarly, when the number of the blowers 102 is plural, the number of the blowers 102 that are turned on and the rotation speed of each of the blowers 102 that are turned on may have a correspondence with the preset pressure threshold. For the explanation and description of this section, reference may be made to the above description when the number of wind turbines 102 is one. To avoid redundancy, it is not described herein.

Referring to fig. 6 and 7, in some embodiments, the flushing system 100 includes a flushing device 130, the flushing device 130 is used for flushing the filtering device 120, and the control method includes:

step S14: and controlling the flushing device 130 to be opened under the condition that the outlet air pressure is smaller than the preset pressure threshold.

In some embodiments, the control module 14 is configured to control the flushing device to be turned on when the outlet air pressure is less than a preset pressure threshold.

Thus, the filtering device is washed by the washing device 130 under the condition that the outlet air pressure is smaller than the preset pressure threshold value. In the example of fig. 2, the flushing device 130 is arranged on top of the filtering device 120. Specifically, the flushing device 130 may include a flusher (not shown) and a driving mechanism (not shown) for driving the flusher to move to flush the filtering device 120.

Optionally, the flushing device 130 may comprise a housing 131, and the flusher may be housed within the housing 131 in case the flushing device 130 is not activated. Upon activation of the flushing device 130, the drive mechanism may drive the flusher out of the housing to flush the filtering device 120.

Optionally, the flusher includes a spray head for spraying the cleaning agent and the flushing agent to the filtering device 120 and a brush for brushing the filtering device 120.

In one example, the preset pressure threshold is 65pa, and the outlet pressure of the air outlet side of the filter device 120 is 55pa, which is smaller than the preset pressure threshold, and at this time, the speaker can be controlled to broadcast: "Please note, filter equipment blocked" speech. At the same time, the drive mechanism drives the spray head and brush to move over the wet filter curtain 122. The spray head sprays cleaning agent on the wet filter curtain 122, and the brush brushes the wet filter curtain 122 in cooperation with the spray head. After the wet filter curtain 122 is brushed, the spray head may spray a rinsing agent to rinse away the dirt and cleaning agents.

Note that, in the example of fig. 6, step S14 follows step S101. It is understood that step S14 may be performed before step S101, or simultaneously with step S101. Fig. 6 is an example only, and does not represent a limitation on the order of step S14 and step S101.

Referring to fig. 8, in some embodiments, the number of the filtering devices 120 is multiple, and the multiple filtering devices 120 are sequentially disposed along the flow direction of the exhaust gas in the exhaust gas treatment chamber 270, and the step S11 includes:

step S112: acquiring the air outlet pressure of the air outlet side of each filtering device 120;

step S14 includes:

step S142: the flushing device 130 is controlled to be opened to flush the filtering device 120 corresponding to the outlet air pressure less than the preset pressure threshold.

In some embodiments, the obtaining module 11 is configured to obtain an air outlet pressure of the air outlet side of each filtering device 120; the control module 14 is configured to control the flushing device 130 to open to flush the filtering device 120 corresponding to the outlet air pressure less than the preset pressure threshold.

In this way, it is achieved that, in the case of a plurality of filter devices 120, flushing is performed for a clogged filter device 120. Specifically, in the example of fig. 2, the number of the filter devices 120 is 3, and 1 pressure sensor 123 is correspondingly disposed on the air outlet side of each filter device 120. Under the condition that the fan 102 is turned on, the air outlet pressure at the air outlet side of each filtering device 120 is obtained through the 3 pressure sensors 123, and then the obtained three air outlet pressures are respectively compared with preset pressure thresholds.

In one example, the three acquired outlet air pressures are all less than the preset pressure threshold, and it may be inferred that all three filter devices 120 are blocked. At this time, the flushing device 130 is controlled to be turned on to flush the three filtering devices 120.

In another example, if the obtained three outlet air pressures are all greater than the preset pressure threshold, it can be inferred that none of the three filter devices 120 is clogged. At this time, the flushing device 130 does not need to be controlled to be turned on.

In another example, of the three obtained outlet air pressures, the outlet air pressure obtained by only the rightmost pressure sensor 123 is smaller than the preset pressure threshold, and it can be inferred that the rightmost filtering device 120 of the three filtering devices 120 is blocked. At this time, the flushing device 130 is controlled to be turned on to flush the rightmost filtering device 120.

In addition, in the case that the number of the filtering devices 120 is plural, the specific value of the preset pressure threshold corresponding to each filtering device 120 may be the same or different. The specific value of the preset pressure threshold is not limited herein.

Referring to fig. 9, in some embodiments, the flushing system 100 includes a water collecting device 140 disposed at the bottom of the filtering device 120, and the control method includes:

step S15: in case the flushing device 130 is switched on, the water collecting device 140 is controlled to drain.

In some embodiments, the flushing system 100 includes a water collection device 140 disposed at the bottom of the filtering device 120, and the control module 14 is configured to control the water collection device 140 to drain when the flushing device 130 is turned on.

Therefore, the collection and the discharge of the waste water after the flushing are realized. Specifically, referring to fig. 10, the water collecting apparatus 140 may include a water collecting tank 141, a drain valve 142, and a drain pipe 143. The drain pipe 143 communicates with the water collecting tank 141 through the drain valve 142, the drain valve 142 opens and closes the drain pipe 143, and water in the water collecting tank 141 can be discharged through the drain pipe 143 when the drain valve 142 opens the drain pipe 143. In a normal case, the drain valve 142 is in a closed state, and in a case where the flushing device 130 is opened, the drain valve 142 is controlled to be opened to drain the water collecting device 140. Further, in order to prevent the unfiltered off-gas from being discharged from the water collecting sump 141 and the drain line 143, in a case where the flushing device 130 is not opened, the drain valve 142 may be in a closed state to close the drain line 143, thereby preventing the unfiltered off-gas from being discharged from the water collecting sump 141 and the drain line 143.

Further, in case that the flushing device 130 is turned on, the water collecting device 140 may be controlled to drain water at regular time. It is understood that the amount of flushing water per unit time of the flushing device 130 is known in advance, and therefore, the water collecting device 140 can be controlled to discharge water at regular intervals according to the amount of flushing water per unit time of the flushing device 130 and the time of flushing.

In addition, the water level of the water collection tank 141 may be acquired, and when the water level of the water collection tank 141 is greater than a preset drain water level, the drain valve 142 is controlled to be opened to drain the water collection apparatus 140.

In addition, a filtering device 144 and a water delivery pump 145 may be disposed in the drain pipe 143, the filtering device 144 may filter the water discharged from the water collecting tank 141, and the water delivery pump 145 may deliver the filtered water to the top of the filtering wet curtain 122 for the filtering wet curtain 122 to utilize.

Referring to fig. 11, in some embodiments, the control method includes:

step S16: under the condition that the flushing device 130 is flushed, obtaining the air outlet pressure of the flushed air outlet side of the filtering device 120;

step S17: and under the condition that the air outlet pressure after washing is smaller than a preset pressure threshold, controlling the prompting device 103 to prompt warning information.

In some embodiments, the obtaining module 11 is configured to obtain an air outlet pressure at an air outlet side of the washed filtering apparatus 120 when the washing apparatus 130 finishes washing; the control module 14 is configured to control the prompting device 103 to prompt warning information when the air outlet pressure after washing is smaller than a preset pressure threshold.

So, realize promoting the staff under the relatively poor condition of washing effect. It is understood that in case the rinsing device 130 is rinsed, if the measured outlet air pressure is still less than the preset pressure threshold, it may be concluded that at least one of the blower 102, the rinsing device 130, the filtering device 120 and the pressure sensor 123 is damaged. Therefore, the prompting device 103 can be controlled to prompt warning information to prompt staff to remove the fault as soon as possible.

Referring to fig. 12, a flushing system 100 according to an embodiment of the present invention includes a prompting device 103, a processor 20 and a memory 30, the processor 20 is connected to the memory 30 and the prompting device 103, the memory 30 stores one or more programs, and the programs, when executed by the processor 20, implement the control method of the flushing system according to any of the above embodiments.

For example, the program when executed by the processor 20 implements step S11: acquiring the air outlet pressure of the air outlet side of the filtering equipment 120 under the condition that the fan 102 is started; step S14: and under the condition that the air outlet pressure is smaller than the preset pressure threshold, controlling the prompting device 103 to prompt alarm information.

In the flushing system 100 according to the embodiment of the present invention, the flushing device 130 is controlled to be turned on when the outlet air pressure at the air outlet side of the filtering device 120 is smaller than the preset pressure threshold, so that the state of the filtering device 120 can be prompted in time to dredge the filtering device 120, prevent the filtering device 120 from being blocked, and facilitate improvement of the efficiency of waste gas treatment.

In particular, the processor 20 and the memory 30 may constitute a computer system. The computer system can be applied to personal computers, servers, mobile phones, tablet computers, specially manufactured control terminals and the like.
