Description
Technical field
The present invention relates to detection technique field, more specifically, the falling temperature technique of high temperature detection device.
Background technology
The equipment to be worked with the condition of high temperature, such as fuel boiler need the operating temperature of care testing device with definite equipment
Working status., it is necessary to detect furnace flame intensity using flame detecting device for fuel boiler, to determine fuel
The working status of boiler.The probe of flame detecting device is installed near burner or furnace wall, and environment temperature is very high, so visiting
Head is typically equipped with dedicated cooling duct, and cooling duct inputs cooling wind to probe, probe is maintained suitable temperature
Under, avoid probe from damaging at high temperature.
Cooling duct is connected to cooling blower, and cooling wind is provided by cooling blower, and cooling down the pressure of wind needs to meet necessarily
Standard, such as cooling wind pressure need to maintain 6000Pa or so so that probe can be lowered to sufficiently low temperature
Degree.When cooling blower cisco unity malfunction for some reason, or when not reaching enough output powers, the pressure of wind is cooled down
Can deficiency.The hypodynamic consequence of cooling wind pressure is that the temperature of probe can not be reduced to safe temperature, and probe can be damaged due to high temperature
It is bad, or service life drastically reduces.
The content of the invention
Present invention is disclosed a kind of cooling device of flame-detecting probe, including：Main cooling blower, spare cooling blower,
Cooling duct, pressure detector and compressed air line.Main cooling blower and spare cooling blower are all connected to cooling duct, cold
But air hose is connected with flame-detecting probe, and main cooling blower forms redundancy with spare cooling blower, is provided jointly to cooling duct
Wind is cooled down, cooling wind cools down flame-detecting probe by cooling duct.It is cold in pressure detector detection cooling duct
But wind pressure, when cooling wind pressure power is less than threshold pressure, compressed air line, which is opened, inputs compressed air into cooling duct.
When pressure detector detects that cooling wind pressure power reaches threshold pressure, compressed air line is closed.Pressure detector
In cooling duct, the threshold pressure of pressure detector can be set as 6000Pa.
Main cooling blower provides cooling wind and causes cooling wind pressure power to reach threshold pressure, and spare cooling blower is closed.It is spare
Cooling blower provides cooling wind and causes cooling wind pressure power to reach threshold pressure, and main cooling blower is closed.Main cooling blower and spare
Cooling blower provides cooling wind so that cooling wind pressure power reaches threshold pressure jointly.
Pressure detector detects that the cooling wind pressure power in cooling duct is less than threshold pressure alarm.
The cooling device of the flame-detecting probe of the present invention can detect cooling wind pressure power in real time, in cooling wind pressure power deficiency
When timely use compressed air and supplemented, maintain cooling wind pressure power so that flame-detecting probe is able to maintain that in appropriate temperature
Degree.When detecting cooling wind pressure power deficiency, the cooling device is also alarmed.
Brief description of the drawings
