The differential pressure sensor Sd is installed in the filter device 130 so that when the pressure inside the filter is higher than the reference value, the environmental monitoring server 30 knows that the filtering function has fallen and notifies this fact.

The flow rate sensor Ss detects the exhaust speed of the purified air discharged through the exhaust period, and if it is higher or lower than the reference value, the environment monitoring server 30 recognizes that an abnormality has occurred and notifies it.

The field controller 20 is installed adjacent to the pollution prevention facility 200 and wirelessly transmits multiple signals input from the sensor module to the environment management server 30.

The environment monitoring server 30 has reference value information as described above, and determines the presence or absence of an abnormality in comparison with sensing information transmitted from the on-site controller, and informs when an abnormality occurs.

If abnormality occurrence information is transmitted from the environment monitoring server 30, the mobile terminal 40 may receive it and respond to the error information.

That is, the mobile terminal 40 may be a mobile phone or other mobile device carried by field workers, and a pollution prevention facility management app may be installed to receive and check information transmitted from the environment monitoring server in real time.

In addition, as described above, in the filter dust collecting facility to which the system of the present invention is applied, as the blowing amount of the exhaust fan 140 is greater than the blowing amount of the pulling means, a differential pressure is generated in the filter device, and the air is transferred to the exhaust blower by the differential pressure. When it is sucked into, filtration is performed in the filter device.

It is preferable that the air intake device provided in such a filter dust collecting facility is configured as shown in FIGS. 3 and 4.

That is, the air is pushed out by the pushing means 110 on one side, and the air is sucked out by the pulling means 120 on the other side, so that contaminated air can be effectively sent to the filter device to the blowing fan with a small capacity and its accessory equipment. have.

The pushing means 110 includes a pushing blower 111 for generating air, and a pushing nozzle 112 having a nozzle hole 112h for injecting air supplied from the pushing blower toward the pulling means.

That is, the pushing means 110 is installed at one end of the gas generating facility, as shown in FIG. 4 below, so that the air ejected through the pushing nozzle 112 covers the upper surface of the gas generating facility and It plays a role and functions to push the harmful gas generated in the gas generating facility toward the pulling means 120.

Of course, between the pushing blower 111 and the pushing nozzle 112 of the pushing means 110, a pushing line 113 for moving to the pushing nozzle of the blower is installed.

In addition, the diameter of the pushing nozzle 112 is ?2mm-30mm, and the distance between the pushing nozzles is 2 ?? of the pushing nozzle diameter. It is preferably 10 times.

Depending on the gas evaporation speed, the air volume per one pushing nozzle is 10ℓ/min-3000ℓ/min.

By designing, design values suitable for gas types and characteristics can be applied.

When the air injected from the shielding curtain nozzle 112c installed higher than the intake duct is pushed to the rear of the pulling means 120 to the outside, harmful gases remaining in the air pushed by the shielding curtain nozzle 112c will be scattered to the outside. I can.

Accordingly, it is preferable that a shielding plate 124 is further installed on one side of the upper portion of the pulling means 120 to block the air formed by the pushing means from flowing to the rear or side of the pulling means.

The shielding plate 124 is formed as a flat plate on both sides, but the suction duct is installed in an arc shape as shown in FIGS. 3 and 4 so that the air discharged from the shielding curtain nozzle 112c is added to the arc-shaped inner surface. It is desirable to let it flow into the inside of the hazardous gas generating facility.

The leak detector Sl may vary depending on the components stored in the tank, but as shown in FIG. 5, it surrounds the tank and is installed in the form of a loop.

The criterion for detecting an abnormality in the environmental monitoring server 30 is made by contrasting with the reference value, and the range of the abnormality is set by setting an upper limit and a lower limit to warn if the difference from the reference value is insignificant, and notify a danger at the time of warning. By managing and repairing the facility in advance, it is possible to prevent future errors or damage to the facility.
