The flame detection device has the beneficial effects that compared with other flame detection systems, the flame detection device of the gasification furnace is provided with a camera and a monitoring display device connected with the camera, so that the flame condition in the furnace can be directly reflected on the picture of a monitor in a control room, the image is very vivid and visualized, and the effect is the same as the fire observation in manual site.
Description
Affiliated technical field:
The utility model relates to a kind of proofing unit, the proofing unit on particularly a kind of vapourizing furnace that is applied in the powdered coal pressuring gasified system methyl alcohol of HT-L.
Background technology:
Have the fine coal pressurization HT-L gasification technology of independent intellectual property right by the domestic first cover of space research institute development, this project utilizes indigenous coal to be raw material, produces methanol feedstock gas, and its gasification installation design scale is for producing 150000 tons of methyl alcohol per year.
The key core equipment of HT-L gasification technology is vapourizing furnace.And the key of vapourizing furnace is a burner, and HT-L stove burner is a combination burner, is made up of a main burner, an igniter burner and a startup burner.Main burner is made up of an oxygen channel and three coal dust passages.The head of burner and body are provided with cooling water coil and chuck, and force to feed the burner recirculated cooling water, to guarantee the particularly temperature-stable of burner head of burner, avoid Yin Gaowen to burn out burner.Be 3 years the work-ing life of whole burner.HT-L stove burner advanced design, rational in infrastructure, convenient and reliable operation can realize throwing from lighting a fire to the continuity of coal.Because in vapourizing furnace when igniting, need at first by time variable control according to strict ratio aerating oxygen and Sweet natural gas, igniter burner is lighted in the priming bar sparking, drop into startup burner by time variable control again, if detect flare up fire by flame detector this moment, illustrate and light a fire successfully, time variable control proportionally strengthens oxygen and gas discharge automatically, and main burner input is prepared according to the setting curve increasing temperature and pressure by system.If detect less than flare up fire, system will think loss of ignition automatically, and car is jumped in time variable control automatically, and cuts off oxygen and Sweet natural gas valve immediately, prevents that a large amount of oxygen, Sweet natural gas from entering vapourizing furnace and blasting.So flame detecting device is very important, whether its steady running decision can drive smoothly.
The utility model content:
One of the purpose of this utility model provides a kind of easy to maintenance, safeguards simply the flame detecting device that working cost is low.
Two of the purpose of this utility model provides a kind of flame detecting device that quick, clear, the directly perceived transmission of the flare up fire of vapourizing furnace can be come out.
Whether reasonably three of the purpose of this utility model provides a kind of operator and can be directly very clearly sees flame situation in the vapourizing furnace from the screen of monitor scope, even the ratio that can judge oxygen and Sweet natural gas according to the brightness of flame flame detecting device.
The technical solution of the utility model is as follows: a kind of vapourizing furnace flame detecting device, comprise and see fiery device, flame detection equipment, signal transmission system and DCS Controlling System (distributedcontrol system, dispersing control system), it is characterized in that: the fiery device of described sight comprises flame-observing hole, the high-pressure carbon dioxide scavenging line, trip valve, and safety screen, described flame-observing hole is positioned at described vapourizing furnace furnace wall near the burner place, described flame detection equipment is positioned at described safety screen, and described signal transmission system is used for the flare up fire that described flame detection equipment observes is transferred to described DCS Controlling System.The setting of the fiery device of described sight is for the flare up fire with gasifier nozzle passes to described flame detection equipment, and wherein, high-pressure carbon dioxide scavenging line, trip valve and safety screen all are in order to protect the safety of described flame detection equipment.
Described flame detection equipment can be accurate camera.Accurate camera can be quick, clear with the flare up fire of the flare up fire vapourizing furnace of vapourizing furnace, intuitively transfer out.
The utility model also can comprise a monitor scope, and described monitor scope links to each other with described flame detection equipment by described signal transmission system.Operator can be directly very clearly see flame situation in the vapourizing furnace from monitor screen, even can judge whether the ratio of oxygen and Sweet natural gas is reasonable according to the brightness of flame.
Compare with other flame detecting device, the beneficial effects of the utility model are:
1, owing to place described vapourizing furnace furnace wall near the burner place described flame-observing hole, detect effective, the accuracy height, False Rate is low.
2, owing to designed the structure of high-pressure carbon dioxide scavenging line, trip valve and safety screen, easy to maintenance, maintenance is simple, and working cost is low.
3, because the monitor scope that is provided with camera and is attached thereto can directly be reflected to the flame situation in the stove on the monitor picture in watch-keeping cubicle, very vivid, directly perceived, the effect fiery with artificial on-the-spot sight is the same.
The utility model can be applied to powdered coal pressuring gasified stoves such as HT-L stove, shell stove, boiler etc.
