Description
Technical field
The utility model relates to a kind of coke oven vertical flame path infrared temperature measurement apparatus that can visual sight, belongs to instrument and meter and industrial automation.
Background technology
The online infrared measurement of temperature of coke oven vertical flame path is a kind of new technology that is conducive to coke oven thermal control and energy-saving and emission-reduction just occurring recently: on the small furnace cover of flue mouth, and installation infrared thermometric optic probe, the bridge of the nose brick temperature measurement on-line of aiming flue bottom.
Up to the present, coke oven vertical flame path thermometric is mainly divided into three modes:
First mode is to adopt hand-held infrared thermometer, every 4 hours, standard quirk flame-observing hole small furnace cover is opened and aimed at one by one flue bottom bridge of the nose brick and carry out thermometric, most domestic coke oven is all adopted in this way at present, the shortcoming of this mode is that thermometric wants armrest to hold aiming, manually button operation thermometric, and temperature measurement error is larger, and start thermometric from first quirk, poor larger to having surveyed last quirk surrounding time.
Second mode is to adopt, on the flame-observing hole small furnace cover of the accurate quirk of coke oven top mark, thermopair is installed, carry out online thermometric, although this method has been avoided error that each manual operation brings and mistiming of thermometric successively, but due to the limited length of thermopair, and general flue has the degree of depth of seven meters of left and right, thermopair can not directly measure the temperature of flue bottom or combustion chambers burn section, and can only calculate the true temperature of firing chamber by setting up a funtcional relationship with the measured temperature that approaches furnace roof of thermopair.
The 3rd mode is exactly to adopt online infrared thermometer to be installed to the mode of carrying out temperature measurement on-line on coke oven vertical flame path small furnace cover, and the difficult point of this thermometric mode is exactly the problem that how to reduce the residing environment temperature of instrument and how reliably to aim at flue bottom bridge of the nose brick.The on-the-spot online infrared temperature measurement apparatus used of coke oven, is mainly divided into two classes at present, and a class is integral type infrared thermometer, and the opticator of temperature measurer and circuit part are all arranged on small furnace cover; Another kind of is optical fiber type infrared thermometer, and the opticator of temperature measurer is arranged on small furnace cover, and circuit part is arranged on that temperature is lower, in the good instrument cabinet of environment, connect optic probe part and circuit part by optical fiber.
What the utility model adopted is exactly optical fiber type infrared thermometer.
The deficiencies in the prior art and shortcoming
The on-the-spot various online infrared thermometer using of coke oven at present, does not solve the problem that how to aim at reliably bridge of the nose brick well.
Summary of the invention
Task of the present utility model is a kind of infrared measurement of temperature equipment that can reliably aim at bridge of the nose brick of design and installation on coking furnace flue small furnace cover.
The feature of the technical solution adopted in the utility model is:
A) by the aiming fixing device with quartz window is installed on small furnace cover, completely cut off flue furnace gas and contact with the direct of optic probe;
B) by being installed on aiming fixing device, universal adjusting device conveniently regulates the sighted direction of probe;
C) prize easily universal adjusting device visual sight flue bottom bridge of the nose brick reliably by be screwed into the sighting bar supporting with it on probe;
D) by design one with the directional light sighting bar that matches of probe light path, in the time of run-home and the probe aiming operation that cooperatively interacted.
