[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0032] The present application provides a purge device, including an air distribution main pipe and at least one purge mechanism; an air inlet is provided on the air distribution main pipe for introducing compressed air; the purge mechanism includes a first connecting pipe, a first valve, a back-blowing pipe and a buffer connecting pipe, one end of the first connecting pipe is connected to the air distribution main pipe, and the first connecting pipe and the air distribution main pipe are arranged at an angle; one end of the first valve is connected to the other end of the first connecting pipe; the back-blowing pipe is connected to the other end of the first valve; the buffer connecting pipe is connected between the back-blowing pipe and the first valve; by introducing compressed air into the air inlet, the compressed air enters the first connecting pipe through the air distribution main pipe, and is then blown through the back-blowing pipe to achieve the purpose of purging dust and other impurities on the surface of the ceramic filter, thereby ensuring that the ceramic filter can always maintain good filtration efficiency; by arranging a buffer connecting pipe between the back-blowing pipe and the first valve, the pressure of the compressed air can be buffered to reduce the shaking of the back-blowing pipe and protect the first valve.

[0033] Some specific implementation methods described below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited to some specific implementation methods described below.

[0034] like Figure 1-Figure 3As shown, an exemplary embodiment of the present application provides a purging device, including an air distribution main pipe 1 and at least one purging mechanism 2; an air inlet 11 is provided on the air distribution main pipe 1 for introducing compressed air; the purging mechanism 2 includes a first connecting pipe 21, a first valve 22, a back-blowing pipe 23 and a buffer connecting pipe 24, one end of the first connecting pipe 21 is connected to the air distribution main pipe 1, and the first connecting pipe 21 is arranged at an angle to the air distribution main pipe 1; one end of the first valve 22 is connected to the other end of the first connecting pipe 21; the back-blowing pipe 23 is connected to the other end of the first valve 22; the buffer connecting pipe 24 is connected between the back-blowing pipe 23 and the first valve 22.

[0035] In this embodiment, the backblowing pipe 23 can be installed at the ceramic filter, and compressed air can be introduced into the air inlet 11. The compressed air enters the first connecting pipe 21 through the air distribution main pipe 1, and then blows through the backblowing pipe 23 to blow away dust and other impurities on the surface of the ceramic filter, thereby ensuring that the ceramic filter can always maintain good filtration efficiency.

[0036] Compressed air is a gas obtained by compressing atmospheric air to a certain pressure using an air compressor. This pressure ensures a good purge effect. However, this pressure can also cause significant vibration in the purge mechanism 2, potentially causing the blowback pipe 23 to shake and damage the ceramic filter or the first valve 22. Therefore, in this embodiment, a buffer connecting pipe 24 is provided between the blowback pipe 23 and the first valve 22 to buffer the compressed air pressure, thereby reducing the shaking of the blowback pipe 23 and protecting the first valve 22.

[0037] The first connecting pipe 21 is arranged at an angle to the gas distribution main pipe 1 to facilitate adjustment of the relative position between the backflush pipe 23 and the ceramic filter. For example, the first connecting pipe 21 is arranged at a 90° angle to the gas distribution main pipe 1. The number of the purge mechanism 2 is not limited and can be one, two, three, etc. For example, Figure 1 Eleven middle purge mechanisms 2 are provided.

[0038] In one embodiment, the purging device further includes a pressure measuring device 3 and a controller. The pressure measuring device 3 is provided on the gas distribution main pipe 1 for detecting the pressure of the gas distribution main pipe 1 . The controller is electrically connected to the pressure measuring device 3 and the first valve 22 .

[0039] In this embodiment, the pressure measuring device 3 has two main functions: one is to detect whether the pressure value of the gas distribution main pipe 1 meets the set value; the other is to detect whether the first valve 22 is working properly. Specifically, when the backflush pipe 23 is needed to purge the ceramic filter, the controller controls the first valve 22 to open, so that the compressed air in the gas distribution main pipe 1 is released. Before the next compressed air fills the gas distribution main pipe 1, the pressure value of the gas distribution main pipe 1 will drop. Therefore, the change in the pressure value of the gas distribution main pipe 1 can be used to determine whether the backflush pipe 23 is working properly, that is, whether the first valve 22 is working properly. Among them, the first valve 22 can be, for example, a solenoid valve, the pressure measuring device 3 can be a pressure sensor, the controller can use a PLC control system, the PLC control system controls the operation of the solenoid valve according to the pressure sensor, and the pressure sensor can monitor the actual working status of the solenoid valve.

[0040] In one embodiment, the pressure measuring device 3 and the air inlet 11 are respectively located at two ends of the gas distribution main pipe 1 .

[0041] In this embodiment, the pressure measuring device 3 and the air inlet 11 are respectively located at the two ends of the air distribution main pipe 1, which can avoid the fluctuation of the value of the pressure measuring device 3 caused by the introduction of compressed air through the air inlet 11, thereby improving the accuracy of the pressure value detection of the air distribution main pipe 1 by the pressure measuring device 3.

[0042] In one embodiment, a plurality of soot blowing nozzles 231 are provided on the backflush pipe 23 along the length direction of the backflush pipe 23 .

[0043] In this embodiment, by providing a plurality of soot blowing nozzles 231 on the back-blowing pipe 23 , the blowing efficiency can be improved.

[0044] In one embodiment, the buffer connecting pipe 24 is a metal hose, one end of which is connected to the first valve 22 , and the other end of which is connected to the backflush pipe 23 .

[0045] In this embodiment, the metal hose is made of high-strength metal material, which has excellent pressure resistance and corrosion resistance, so that it can maintain stable performance in harsh environments. The metal hose also has good elasticity and bending resistance, which can make it have both mechanical strength and buffering properties to extend the service life of the buffer connecting pipe 24.

[0046] In one embodiment, the purge mechanism 2 further includes a second connecting pipe 25 , one end of the second connecting pipe 25 is connected to the first valve 22 , and the other end of the second connecting pipe 25 is connected to the metal hose.

[0047] In this embodiment, the metal hose is connected to the first valve 22 via a second connecting pipe 25 to ensure the stability of the connection between the two. The second connecting pipe 25 and the backflush pipe 23 can both be made of hard steel pipes to ensure their strength and stability.

[0048] In one embodiment, the metal hose is connected to the second connecting pipe 25 and the backflush pipe 23 via a flange 26 .

[0049] In this embodiment, the metal hose, the second connecting pipe 25, and the backblowing pipe 23 are connected by a flange 26, so that they can adapt to different pipe sizes and pressure levels. In addition, the connection through the flange 26 can distribute the stress at the connection to the entire flange 26, thereby reducing local stress concentration and improving the stability of the device structure.

[0050] In one embodiment, the purge mechanism 2 further includes a second valve 27 , one end of the second valve 27 is connected to the first connecting pipe 21 , and the other end of the second valve 27 is connected to the gas distribution main pipe 1 .

[0051] In this embodiment, by providing a second valve 27 between the first connecting pipe 21 and the main gas distribution pipe 1, the flow rate and volume of the compressed air in the pipe can be adjusted, and the pressure in the device can also be adjusted. The second valve 27 can be a manual valve, which also facilitates maintenance of the device.

[0052] In one embodiment, the purging device further includes an alarm device, and the alarm device is electrically connected to the controller.

[0053] In this embodiment, an alarm device can be provided to provide an early warning or alarm for abnormal conditions of the purge device. For example, the pressure measuring device 3 detects the pressure value of the gas distribution main pipe 1 to determine whether the first valve 22 is operating normally. When the pressure value is detected to be lower than the set lower limit, the detection signal is transmitted to the controller. The controller automatically identifies the first valve 22 at the associated position and issues a warning to the first valve 22 at the corresponding position through the alarm device, and marks it in yellow on the configuration control interface. At the same time, the PLC program sets a timing function. When the pressure measuring device 3 detects that the pressure value has not changed after the timing exceeds the set time, the PLC control system pops up a fault maintenance warning to facilitate the operator to check and repair the fault; when the pressure value detected by the pressure measuring device 3 changes within the set time, the yellow warning of the corresponding first valve 22 disappears and normal operation is restored.

[0054] In one embodiment, the purge device further includes a drainer 4 , which is located at the bottom of the gas distribution main pipe 1 .

[0055] In this embodiment, a drainer 4 is provided at the bottom of the main gas distribution pipe 1 to facilitate the drainage of condensed water in the main gas distribution pipe 1 and to facilitate the deposition of condensed water in the main gas distribution pipe 1 .

[0056] To sum up, the purging device of the present application can have a good purging effect on the ceramic filter, and can also monitor the working condition of the first valve 22 in real time, and can realize accurate monitoring to avoid accidents caused by failure of the first valve 22, reduce the labor intensity of maintenance operators, improve work efficiency and automation level, and at the same time effectively avoid safety hazards caused by operation.
