Abstract
The utility model discloses an ethylene cracking furnace boiler tube wall temperature real -time supervision device, include the support frame, set up driving motor, thermoscope and guide rail on the support frame, but the thermoscope is installed on the guide rail through moving mechanism, but the driving motor drive moving mechanism remove so that the temperature of all boiler tubes can be gathered to the thermoscope along the guide rail. This ethylene cracking furnace boiler tube wall temperature real -time supervision device accuracy in real time automatically measures boiler tube outward appearance temperature, simple structure, convenient operation and the portable of device.
Description
Technical field
The utility model relates to petrochemical industry, particularly relates to a kind of Ethylene Cracking Furnace Tubes wall temperature real-time monitoring device.
Background technology
Ethylene production adopts tubular type pyrolysis technology, and aborning, cracking furnace tube plays heating raw and reactor, is the key component of cracking technology, and the operation conditions of pyrolysis furnace directly affects ethylene yield and quality.Because cracking furnace pipe subjects the effect of high temperature, corrosion and load for a long time, these effects can make surface oxidation and the coking of pyrolysis furnace local, cause the decline of boiler tube mechanical property, material phase transformation, wash away the faults such as thinning, even cause the Cracking Failure of boiler tube.In this failure procedure, temperature is main influence factor.
In order to ensure cracking furnace tube safe operation, and provide process foundation for the maintenance of fault boiler tube, must carry out monitor and forecast to furnace tube temperature, to make judgement promptly and accurately to the operation conditions of boiler tube, the means of employing are that monitoring cracking furnace tube wall temperature is to judge boiler tube internal temperature.
The method of current measurement furnace wall temperature has two kinds.One method arranges thermal infrared imager in stove, this method can carry out taking pictures of leak case and insulating efficiency, but the real-time monitoring of boiler tube external skin temperatures can not be used for, therefore only as the reference data of pipe surface temperature, and expensive, the problem such as reliability is low, inconvenient operation can be there is.Another kind method is the artificial observation outside stove, specifically artificial hand-held infrared thermometer, locates thermometric by the flame-observing hole of pyrolysis furnace by artificial by pipe.Although method is feasible, because test point is near fire door, by the impact from thermal energy radiation powerful in stove, workman is difficult at short notice by complete for disposable for all boiler tubes survey, and usually will divide intermittent operation several times, the reliability of measurement and accuracy cannot ensure.Qualitative analysis that is general, local can only be realized, online quantitative test accurately in real time can not be accomplished.
Realize measuring boiler tube external skin temperatures real-time and accurately, and then determine that in stove, in pipe, temperature variation all has important practical significance to the security of raising ethane cracking furnace productive capacity, production and economic benefit.
Utility model content
The purpose of this utility model addresses the deficiencies of the prior art, and provide a kind of Ethylene Cracking Furnace Tubes wall temperature real-time monitoring device, the technical scheme of employing is as follows:
A kind of Ethylene Cracking Furnace Tubes wall temperature real-time monitoring device, comprise bracing frame, be arranged at drive motor, temperature measurer and guide rail on bracing frame, described temperature measurer is arranged on guide rail by movable mechanism, and described drive motor drives movable mechanism to move to make temperature measurer can gather the temperature of all boiler tubes along guide rail.
In the utility model, drive motor drives movable mechanism to move along guide rail, thus temperature measurer is moved along guide rail, in moving process, temperature measurer just can collect the temperature data of all boiler tubes in stove, carry out by pipe location thermometric without the need to artificial hand-held temperature measuring device, achieve that stove is outer remote, noncontact and automatically measure the object of furnace wall temperature.
As preferably, described temperature measurer is infrared thermometer.
As preferably, described guide rail is arc guide rail, and the center of circle of described arc guide rail is the center that stove mouth seen by pyrolysis furnace.
Infrared thermometer moves along arc guide rail, due to the center of circle of arc guide rail in sight stove mouth in the heart, therefore the infrared ray that infrared thermometer sends all pass through the center of sight stove mouth at any time.Therefore, the temperature data of corresponding boiler tube can both be collected at any time at the structural infrared thermometer of arc guide rail, after infrared thermometer moves to the other end from one end of arc guide rail, just can by complete for the temperature data record of all boiler tubes.
The radius size of described arc guide rail should ensure that temperature measurer is apart from the distance safety seeing stove mouth, so can prevent the heat from seeing stove mouth from causing damage to infrared thermometer.As preferably, the radius of described arc guide rail should be greater than 800mm.
As preferably, described movable mechanism comprises rack and pinion drive mechanism.
Arc guide rail arranges rack and pinion drive mechanism, gear is arranged on arc guide rail by tooth bar, motor-driven gear makes movable mechanism move along arc guide rail, thus infrared thermometer is also and then mobile, and infrared thermometer just can gather the wall temperature data of corresponding boiler tube when mobile.
As preferably, support frame as described above comprises platform, the first support bar and the second support bar, and described platform, the first support bar and the second support bar are hinged cooperation, form four-bar mechanism.
As preferably, described platform is foldable platforms, and described first support bar is collapsible first support bar.
Be foldable platforms by Platform Designing, the first support bar is designed to folding first support bar.Foldable platforms, collapsible first support bar and the second support bar are hinged and form folding four-bar mechanism.During work, four-bar mechanism forms an equilateral triangle, and namely the length of foldable platforms, the length of folding first support bar and the second support bar hinge are equal with the length of upper part.So just can realize freely changing and bracing frame is easy to carry between the work of foldable platforms and folding and unfolding state.
As preferably, described foldable platforms is provided with the positioning groove for docking with fire door channel-section steel.
When measuring, positioning groove accurately being docked with fire door channel-section steel, the second support bar roller end and fire door lower margin root touch, to make the more accurate positioning between infrared thermometer and sight stove mouth center O.
The beneficial effects of the utility model: the Ethylene Cracking Furnace Tubes wall temperature real-time monitoring device that the utility model provides accurately automatically can measure boiler tube external skin temperatures in real time, the structure of device is simple, easy to operate and be easy to carry.
