Embodiment 1

[0041] 1) Press the start button 51 to start the fan;

[0042] 2) The wind speed sensor 71 detects the wind speed in the main pipeline. When the wind speed of metal dust in the main pipeline is less than 23m / s, or when the wind speed of non-metallic dust is less than 18m / s, the control module 2 controls the fault indicator light 43 to light up and control the alarm The device 6 reports to the police, and the control state indicator light 4 displays the monitoring state correspondingly. At this time, the staff needs to check and confirm the wind speed monitoring value displayed on the man-machine interaction board 3;

[0043] 3) After confirming the abnormal situation, the staff operates the human-computer interaction board 3 to manual mode and eliminates the alarm, and adjusts the corresponding components in the negative pressure dust removal system. After the adjustment is completed, the staff confirms the human-computer interaction board 3 again After the wind speed is norma...

Embodiment 2

[0047] 1) Press the start button 51 to start the fan;

[0048] 2) The temperature sensor 73 detects the temperature in the pipeline. When the temperature in the pipeline is higher than the set value, the control module 2 controls the fault indicator light 43 to light up and controls the alarm 6 to alarm, and the control status indicator light 4 displays correspondingly Monitoring status, at this time, the staff needs to check the temperature monitoring value displayed on the human-computer interaction board 3 and confirm it;

[0049] 3) After confirming the abnormal situation, the staff operates the human-computer interaction board 3 to manual mode and eliminates the alarm, and adjusts the corresponding components in the negative pressure dust removal system. After the adjustment is completed, the staff confirms the human-computer interaction board 3 again After the temperature is normal, readjust the manual mode to automatic mode;

[0050] 4) Press the stop button 52, the fa...

Embodiment 3

[0053] 1) Press the start button 51 to start the fan;

[0054] 2) The differential pressure sensor 72 detects the differential pressure in the pipeline. When the differential pressure value is greater than the set reference value, the reference value is set as follows: when all branch valves are opened, the displayed differential pressure value rises by 15% as a reference value, the control module 2 controls the fault indicator light 43 to light up and controls the alarm 6 to alarm, and the control status indicator light 4 correspondingly displays the monitoring status. At this time, the staff needs to check the pressure difference monitoring value displayed on the man-machine interaction board 3 and To confirm, the control module 2 controls the opening of the air supply valve to compensate for the pressure difference. After the pressure difference returns to normal, the control module 2 controls the closing of the air supply valve;

[0055] 3) After confirming the abnormal si...

Abstract

The invention discloses real-time negative pressure dust removal system control equipment, and belongs to the technical field of negative pressure dust removal system control. The control equipment comprises an explosion-proof box body, and a control module, a man-machine interaction board, a control state indicating lamp, a control button and an alarm which are arranged in the explosion-proof box body, the man-machine interaction board is a touch display board, the alarm is a buzzer, the man-machine interaction board, the control state indicating lamp, the control button and the alarm are all electrically connected with the control module, the control module is electrically connected with a sensor module, and the control module is electrically connected with an electric air valve. The air speed, the temperature, the pressure difference and the material level of the material bin in the negative pressure dust removal system are monitored in real time, all parameters are displayed on the man-machine interaction board in a centralized mode, automatic alarm is achieved, and alarm elimination and control mode switching are controlled through the man-machine interaction board, so control operation is easy and convenient, and control performance is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of negative pressure dust removal system control, and in particular relates to a real-time negative pressure dust removal system control device and control method. Background technique [0002] The dust removal system plays an important role in improving the air conditions of residential buildings and production workshops, protecting people's health, and improving labor productivity. It is one of the active and effective improvement technical measures in controlling industrial dust prevention and anti-virus work. In the negative pressure dedusting system, the deduster is set before the fan, the gas flowing through the fan has been dedusted, the dust concentration is low, the wear of the fan is greatly reduced, and the operating life is prolonged. In the real-time negative pressure dust removal system, multiple separate monitoring modules are often used to detect and control the operating conditions in the sy...
