Description
Technical Field
The invention relates to the technical field of detection, in particular to a cooling technology of high-temperature detection equipment.
Background
Devices operating at high temperatures, such as fuel boilers, require real-time detection of the operating temperature of the device to determine the operating state of the device. For a fuel boiler, a flame detection device is required to detect the flame intensity of a hearth to determine the working state of the fuel boiler. The probe of the flame detection device is arranged near the burner or the furnace wall, and the environment temperature is very high, so the probe is generally provided with a special cooling air pipe, and the cooling air pipe inputs cooling air to the probe so as to maintain the probe at a proper temperature and avoid the probe from being damaged at a high temperature.
The cooling air duct is connected to a cooling fan, and cooling air is supplied by the cooling fan, and the pressure of the cooling air needs to meet certain criteria, for example, the pressure of the cooling air needs to be maintained around 6000Pa, so that the probe can be lowered to a sufficiently low temperature. When the cooling fan does not operate properly for some reason or a sufficient output power is not achieved, the pressure of the cooling air may be insufficient. The consequence of insufficient cooling air pressure is that the temperature of the probe cannot be reduced to a safe temperature, the probe may be damaged due to high temperature, or the service life is drastically reduced.

Fig. 1 discloses a schematic structure of a cooling device of a flame detection probe according to the present invention.
Detailed Description
Referring to fig. 1, the present invention discloses a cooling device of a flame detection probe, comprising: a main cooling fan 11, a standby cooling fan 12, a cooling air duct 13, a pressure detector 14 and a compressed air line 15. The main cooling fan 11 and the standby cooling fan 12 are both connected to the cooling air pipe 13, the cooling air pipe 13 is communicated with the flame detection probe, the main cooling fan 11 and the standby cooling fan 12 form redundancy, cooling air is supplied to the cooling air pipe 13 together, and the cooling air cools the flame detection probe through the cooling air pipe 13.
The pressure detector 14 detects the cooling air pressure in the cooling air duct, and when the cooling air pressure is smaller than the threshold pressure, the compressed air line 15 opens to input compressed air into the cooling air duct 13. When the pressure detector 14 detects that the cooling air pressure reaches the threshold pressure, the compressed air line is closed. If the cooling air pressure in the cooling air duct 13 always reaches the threshold pressure, the compressed air line is always in a closed state. If the cooling air pressure in the cooling air duct 13 is less than the threshold pressure, the compressed air line 15 is opened to supply compressed air to raise the cooling air pressure in the cooling air duct 13, and after the cooling air pressure reaches the threshold pressure again, the compressed air line 15 is closed again. As shown in fig. 1, a pressure detector 14 is installed in the cooling air duct 13, and the threshold pressure of the pressure detector 14 may be set to 6000Pa.
The main cooling fan 11 and the standby cooling fan 12 form redundancy, and the main cooling fan 11 and the standby cooling fan 12 have the following three working modes: the main cooling fan alone provides cooling air such that the cooling air pressure reaches a threshold pressure and the backup cooling fan is turned off. Or the standby cooling fan independently supplies cooling air so that the pressure of the cooling air reaches a threshold pressure, and the main cooling fan is turned off. Or the main cooling fan and the standby cooling fan together provide cooling air such that the cooling air pressure reaches a threshold pressure.
The pressure detector 14 detects that the cooling air pressure in the cooling air duct 13 is smaller than the threshold pressure and gives an alarm. To prompt the staff to overhaul the main cooling fan and the standby cooling fan. According to the above-described operation mode, when the pressure detector 14 detects that the cooling air pressure in the cooling air duct 13 is less than the threshold pressure, it is indicated that there is a possibility that the main cooling fan and the backup cooling fan have a malfunction.
The cooling device of the flame detection probe can detect the pressure of cooling air in real time, and the cooling air is supplemented by using compressed air in time when the pressure of the cooling air is insufficient, so that the flame detection probe can be maintained at a proper temperature. The cooling device also alarms when insufficient cooling air pressure is detected.
