Description
Technical field
The invention belongs to monitoring equipment field, particularly relate to a kind of stove high-temperature monitor.
Background technology
Industrial furnace mainly processes difficulty by overheated molten bath and melts furnace charge, such as nickel minerals etc..In actual production process in order to
The working conditions such as monitoring burner hearth internal mineral thawing and furnace wall state, facilitate field personnel to run in understanding burner hearth in real time
Operating mode, needs at the internal built-in electronic monitoring equipment that can bear high temperature of burner hearth.But, for there is no the common of thermal insulation protection
The high heat that monitoring device is brought when can not bear furnace operation, such as more than 1500 DEG C, or for common high temperature monitoring
Facility has angle limitation for observing burner hearth internal condition, it is impossible to enough panorama situations in passing on burner hearth in real time, for prison
Control effect has limitation, if occurring special circumstances cannot accurately judge the internal accident point of burner hearth, and in stove, sand and dust hold
Easily enter camera head protecting sleeve pipe, it is difficult to clear monitoring burner hearth inner case, the economy of enterprise is caused heavy losses.
At present, prior art has employing picture pick-up device is built in the stove high temperature being monitored inside burner hearth to monitor
Device, also has employing array photographic head die set.Such as, Authorization Notice No. is the Chinese patent disclosure of CN201429337Y
A kind of water-cooling gas-seal type high-temperature industrial television system, including the water-cooling base plate being arranged on kiln inwall, is arranged on water-cooled base
Actuating device on plate, inserted high temperature resistant camera head by actuating device, be arranged on the air water electricity field box near actuating device
And the warning box that is arranged in control room and watch-dog.It is characterized in that, described Camera Probe includes that water-cooling air-sealing type is visited
Headgear and the camera head being arranged in water-cooled envelope formula probe sheath, described actuating device is driven by motor and passes through resistant to elevated temperatures
Installation base plate is fixed on the outer wall of stove.Described water-cooling air-sealing type probe sheath, has coolant outlet, entrance and cooling gas
Entrance, cooling water enters in the interlayer of probe sheath from entrance, discharges through coolant outlet after heat exchange, and cooling gas is from cooling
Gas entrance enters in probe sheath, in photographic head enters kiln.This technical scheme uses trocar sheath water-cooled, inner sleeve air cooling sealing gland
Mode, cools down camera head.
The heat-resisting outer layer computer camera protective cover of this water-cooling gas-seal type high-temperature industrial television system uses water-cooled protecting device,
For China's rich ore water-deficient area, water scarcity, energy consumption is relatively big, is unfavorable for energy-conservation.Internal camera head uses ventilation type cooling,
Cooling gas through photographic head and is emitted into inside burner hearth and is unfavorable for that burner hearth internal gas component controls, it is impossible to for all-oxygen combustion
Time burner hearth monitoring.Further, owing to cooling air is passed through inside burner hearth, NO can be improvedXDischarge capacity, is unfavorable for that energy-saving and emission-reduction image
Head monitors that angle has unicity, it is impossible to completely see internal condition when burner hearth runs.
Authorization Notice No. is that the Chinese patent of CN100529107C discloses a kind of blast furnace inner high temperature industrial TV device,
Including probe, it is characterized in that, in the front portion of probe equipped with the cooling base for protecting probe, at the middle part of probe equipped with being used for
The fixing ring flange popped one's head in and play sealing function, at the rear portion of probe equipped with the The Cloud Terrace for rotating detector, under The Cloud Terrace
Side is equipped with fixing the drive mechanism being connected for mobile probe and with cooling base and The Cloud Terrace.Image pullover by being arranged in sleeve pipe
Foremost, situation in stove is observed.Cooling base is used two-way gas to carry out air-cooled by the present invention, and probe is carried out water-cooled.
This invention photographic head outer wall type of cooling is water-cooled, and this type of cooling cannot be arranged in areas of serious, tool
There is the strongest limitation, and be unfavorable for energy efficient.This invention cooling base uses air sealed cooling system, and air is through taking the photograph
As head is anterior and is passed through to burner hearth by anterior peephole, which can increase NOXDischarge capacity, and cannot effectively control
Burner hearth internal gas component, it is impossible to apply to the burner hearth of total-oxygen combustor, even if using the discharging modes of air sealed, experiment proves
Still cannot effectively prevent burner hearth internal dust entrance sleeve pipe interior and disturb monitoring effect.Blast furnace inner high temperature industrial TV fills
Putting, in this invention, photographic head monitors that angle has unicity, it is impossible to completely see internal condition when burner hearth runs.
