Background technology
The test of flammable liquid combustion flame temperature is an extremely important problem of petrochemical industry security technology area, and it has very important meaning for the judgement of the fired state of combustible, prediction and diagnosis.At present, test flame temperature of combustion method is roughly divided into contact method and eyes with non-contact method.Contact method is the direct test flame of sensor mainly, becomes electric signal transmission to sampling thief temperature inversion.Eyes with non-contact method is all utilize the characteristic such as simulating flame or radiation heat, and concrete grammar mainly comprises the flame temperature measurement method of Digital Image Processing, utilizes the method for the full detail fire detecting flame actual temperature of radiation spectrum; Michelson interference measures the method for flame temperature; Duochrome method flame monitoring; Non-contacting infrared thermometry measurement etc.
Patent CN102221420A line formula flame temperature sensor, is characterized in that, comprises at least one body, a pipe box Signal connector and a core body Signal connector; Described body comprises core body, semiconductor ceramic coating and pipe box; Described semiconductor ceramic coating is arranged on one end of described core body, and this semiconductor ceramic coating is wrapped in described core body; Described pipe box is pipeline, and one end of this pipe box is enclosed within the outside of described semiconductor ceramic coating; Described pipe box Signal connector is connected with the other end of described pipe box; Described core body Signal connector is connected with the other end of described core body
The patent No. is CN1851419, this utility model discloses a kind of temperature field, the pick-up unit of flame image and detection method thereof, by the image adopting vision-mix reception fiber array and computer temperature field Video processing can provide temperature field in time, simultaneously to vision-mix to receive in fiber array regularly isolated optical fiber temperature by the light splitting of Y shape fiber coupler, adopt color comparison temperature measurement technology, accurately can detect the temperature of each set point in temperature field.
Use sensor contacts method thermometric, be generally used for test combustion furnace or some high temp objects, this is because the structure composition of thermal sensor, one end is high temperature resistant conductor or semiconductor temperature probe, the other end is core body Signal connector connection signal line, core body joint and the equal non-refractory of signal wire, very easily burn non-refractory joint one end so traditional application sensors direct temperature measurement is infeasible because the higher and form of burning of flame temperature changes at any time.
Eyes with non-contact method is exactly mainly two kinds of methods, and one simulates flame temperature by simulation means, carries out computational analysis by the software of some row.Simulation needs a large amount of test figures to support, and different fuel temperature of combustion there is not comparability, so be difficult to ensure that each fuel combustion temperature has sufficient Data support, the flame temperature for some fuel is difficult to present accurately.Another kind is converted to temperature signal by the color of then flame, the signal such as radiation heat and optics.Thermo-optical, radiation characteristic non-cpntact measurement combustion flame temperature, measuring temperature is all the peripheral reflected temperature of flame, heat radiation by environment temperature, by ambient sunlight power etc. condition affected, so the temperature data application condition that experimental test goes out is large.
Prior art has just done detection method and the image recognition of introduction and high-temperature field flame image to the structure of flame temperature sensor and connection.Do not relate to the internal and external temperature to the fire prevention process of pyrostat and using method and test different time, diverse location flammable liquid combustion flame.
The utility model solves this problem targetedly.
Utility model content
Technical problem to be solved in the utility model be in prior art sensor serviceable life shorter, the inaccurate problem of test result, a kind of new flammable liquid flame temperature proving installation is provided.This device is used in the test of flammable liquid flame temperature, has longer, test result advantage accurately in sensor serviceable life.
For solving the problem, the technical solution adopted in the utility model is as follows: a kind of flammable liquid flame temperature proving installation, comprise food tray, pyrostat, galvanized conduit, fire-proof mud, rock wool, fire blanket, dynamic acquisition device, signal wire, pyrostat is connected with signal wire, periphery, pyrostat working end is surrounded by rock wool, glass wool, fire blanket, be placed in galvanized conduit, pyrostat metal probe is with till stretching out the zinc-plated mouth of pipe, zinc-plated mouth of pipe fire-proof mud seals, fire-proof mud is blocked up into galvanized conduit at least 3cm, the galvanized conduit outer wall of pyrostat is surrounded by rock wool, rock wool skin is surrounded by glass wool, glass wool skin is surrounded by fire blanket, signal wire one termination pyrostat, another termination dynamic acquisition device.
