The pulse ash removal system comprises an air source 30, an air pipeline 31, an air distribution box 32, an air purifying chamber 35 and an injection pipe 33, wherein the air source 30 is connected with the air distribution box 32 through the air pipeline 31, and the air distribution box 32 is arranged on the outer side of the shell 1 along the shell wall of the shell 1 and corresponds to the air purifying chamber 35 in the height direction. Air-purifying chamber 35 is in being close to the top position in 1 inner chamber of casing, and air-purifying chamber 35 downside is air inlet chamber 11, has the horizontal colored sheet 36 that extends in the air-purifying chamber, is equipped with a plurality of colored sheet holes on the colored sheet 36, and fixed mounting filter bag 2 on the colored sheet hole, filter bag 2 droop to air inlet chamber 11 in, filter bag 2 is the matrix and arranges. The housing 1 is provided with an air inlet communicating with the air inlet chamber 11 and an air outlet communicating with the air purification chamber 35.
The air purifying chambers 35 are independent of each other, the air distributing boxes correspond to the air purifying chambers one by one, and each air purifying chamber, the corresponding air distributing box and the corresponding filter bag form an independent dust removing unit. Each air distribution box 32 is communicated through an air transmission pipeline 31, an injection pipe 33 is connected with the air distribution boxes 32 and extends into the air purification chamber, and the injection pipe is provided with injection holes which are in one-to-one correspondence with the filter bag openings. Specifically, the gas distribution box 32 has a rectangular tube structure, the injection pipes 33 are arranged perpendicular to the gas distribution box 32, a plurality of electromagnetic pulse valves 34 are installed on each gas distribution box 32 in the length direction of the gas distribution box, the gas outlets of the electromagnetic pulse valves are connected with the injection pipes in a one-to-one correspondence manner, and the electromagnetic pulse valves 34 can be switched on and off between the gas distribution box 32 and the corresponding injection pipes 33. The injection pipe 33 corresponds to the rows of filter bags 2 in one dust removal unit in the up-down direction, the injection pipe 33 is provided with injection holes 330 corresponding to the filter bags 2 one by one, and the injection holes 330 correspond to the mouths of the filter bags 2 and can blow back the filter bags 2.

In this embodiment, the fault detection system includes the control host 4, the pressure sensor 40, and the particulate matter detection module. Wherein, the main control unit 4 includes a PLC control box 42 and a computer 43, and the pressure sensor 40 and the particulate matter detection module are connected with the PLC control box 42. The pressure sensors 40 are mounted on the gas distribution boxes 32 and used for detecting air pressure changes in the gas distribution boxes 32, and the particulate matter detection modules are arranged in the air purification chambers 35 of the dust removal units and can measure the concentration of particulate matters with specific particle sizes in the filtered industrial flue gas in the air purification chambers 35. In this embodiment, the flue gas dust removal system is used for treating flue gas in a kiln head of a dry cement production line, and the particle size of particulate matters in the flue gas is mainly concentrated between PM2.5 and PM10, so that the particulate matter sensor adopts a PM2.5 sensor capable of detecting the concentration of PM2.5 to PM 10. The PM2.5 sensor and the pressure sensor 40 transmit the measured signals to the PLC control box 42, and the PLC control box 42 processes the received signals and then reflects the pressure data and the PM2.5 concentration data to the host computer 43.
Each PM2.5 sensor and pressure sensor 40 is numbered. The database of the computer 43 stores the PM2.5 concentration data in the air purifying chamber 35 and the pressure change curve in the gas distribution box 32 under the normal operation of the bag type dust collector, the computer 43 compares the measured PM2.5 concentration data and the pressure change curve with the stored PM2.5 concentration data in the air purifying chamber 35 and the pressure change curve in the gas distribution box 32 under the normal operation of the bag type dust collector, when the error exceeds a set value, a warning message is sent, and a worker can know the number of a sensor with abnormal data and lock the abnormal position of the bag type dust collector, so that the maintenance treatment can be carried out in time.
In the actual production process, the flue gas after purification and dust removal is found to have a particle concentration exceeding the standard often because the filter bag 2 is damaged and cannot play a role in reliable filtering, so that the particle concentration exceeding the standard is detected by the particle detection module in the air purification chamber 35, and the filter bag 2 of the dust removal unit can be judged to be damaged. Specifically, when the data recorded by the PM2.5 sensor is compared with the data in the database in the computer host 43 during use, the data recorded by the PM2.5 sensor is smaller than the data in the database in the computer host 43, or is larger than the data in the database in the computer host 43 with an error within 5%, and it is determined that the filter bag 2 is normal, and no warning is given. When the data recorded by the PM2.5 sensor is larger than the data in the database in the computer host 43 and the error is larger than 5%, the filter bag 2 is judged to be damaged, warning information is sent out, the abnormal PM2.5 sensor number is displayed, and a worker can quickly lock the position of the dust removal unit with the damaged filter bag 2 and conduct targeted maintenance.
In the actual production process, it is found that, once the electromagnetic pulse valve 34 on the gas distribution box 32 fails, the air pressure in the gas distribution box 32 is often unstable, and therefore, when the pressure sensor 40 on the gas distribution box 32 detects that the air pressure in the gas distribution box 32 is abnormal, it can be determined that the electromagnetic pulse valve 34 on the gas distribution box 32 has a failure. Specifically, when the upper electromagnetic pulse valve 34 of the gas distribution box 32 is turned on, the PLC control box 42 feeds back a signal to the pressure sensor 40 on the gas distribution box 32, and after receiving the signal, the pressure sensor 40 starts to record a pressure change curve of the gas distribution box 32 when the electromagnetic pulse valve 34 is turned on, and transmits the data to the PLC control box 42 at all times, and after being processed by the PLC system, the data is transmitted to the host computer 43 of the control center, and is compared with the pressure change curve of the gas distribution box 32 in a normal operation state stored in the host computer 43, and the pressure change curve is displayed on the host computer 43. When the error between the actual pressure change curve and the stored pressure change curve is within 5%, the system judges that the electromagnetic pulse valve 34 is normally operated. When the error is greater than 5%, the system judges that the electromagnetic pulse valve 34 is in failure, and at the moment, alarm information is displayed on the computer host 43. The maintainer can lock the position of the gas distribution box 32 where the failed electromagnetic pulse valve 34 is located quickly according to the alarm information, and the maintenance is carried out in a targeted manner.
The flue gas dust removal system enables workers to quickly lock the dust removal unit where the fault gas distribution box or the fault filter bag is located according to the alarm information, so that the fault response speed and the fault maintenance efficiency are improved, and the maintenance efficiency of the bag type dust collector is improved.
