Description

The internal combustion formula torch lighter that soars

The utility model belongs to high-altitude torch ignition technical field, is the igniter that is used for oil, lights the high-altitude torch when chemical system burns waste gas.

The waste gas environmental pollution that the petrochemicals manufacture process produces is serious, the general way of all taking the high-altitude to burn is eliminated waste gas, all there is the torch facility in various oil plants, chemical plant, according to pertinent regulations, torch must be arranged on the height of ground more than 80 meters, and waste gas can be transported on the torch through piping, when needs burn waste gas, open valve and make waste gas rise to the torch place, with the very little torch, the process that just can burn waste gas lighted through pipeline.Yet lighting torch is the work of a difficulty, and the way of Cai Yonging had multiplely in the past, and what for example have draws the torch that is stained with kerosene to light torch with pulley, and this method is both dangerous also unreliable; What have upwards ignites gradually with fuse primer, runs into the strong wind sky and just can draw; Have with the flare pistol discharge signal bullet torch that ignites, this way accuracy rate is very low; The ball of up striking sparks in manage that has all misfires torch often several man-hours.The way of lighting torch close with the present invention is to adopt electrode discharge to light torch, the facility that this way adopts as shown in Figure 1, this facility mainly contains torch assembly (1), Device in Gas conduit (2), electrode (3) and high pressure magnetic bottle (4) are formed, the a little higher than torch assembly of Device in Gas conduit, electrode (3) is to make with the curved angle of stainless steel rod, it has certain clearance apart from the Device in Gas catheter tip, high pressure magnetic bottle (4) is used for connecting high-tension bus-bar, fixed electrode (3) is also apparatus insulated with all the other, when needs are handled waste gas, the control Device in Gas makes it to rise to the top from conduit (2), waste gas also is transported to the top in torch assembly (1), then the high-tension electricity that produces by high pressure generator through high-voltage line and high pressure magnetic bottle (4) to electrode (3), locate discharge generation electric arc at electrode (3), so light the Device in Gas of conduit (2), the Device in Gas of burning is lighted torch (1), and the work of burning waste gas begins to carry out, torch burns down always, till putting out certainly.This way has following disadvantage: 1. stainless steel rod is melted by burning in Device in Gas and torch burning process as electrodes exposed in the open easily, causes the gap between Device in Gas conduit (2) and the electrode (3) to increase, and causes and can not light Device in Gas.2. in the hot environment of high pressure magnetic bottle (4) when also being in torch burning,, high pressure is revealed, caused and to strike sparks because the variations in temperature fire causes that magnetic bottle bursts.3. light the torch wind-engaging to influence, make waste gas in the torch assembly (1) when the direction of Device in Gas conduit (2) is blown as wind direction, torch is easily lighted, otherwise just misfires.4. run into and can light torch for a short time rainy day.5. Device in Gas is burnt all the year round like as altar lamp, and energy waste is very big.

The purpose of this invention is to provide a kind of internal combustion formula torch lighter that soars, the high-altitude torch is lighted not influenced by weather environment, ignition effectiveness height, safe and reliable is convenient to installation and maintenance, and realizes automation control, also has energy-saving effect.

Internal combustion soar the formula igniter structure as shown in Figure 2, this igniter mainly is made up of torch assembly (1), Device in Gas conduit (2), ignitor (3), high pressure generator (4), anti-airduct (5) and igniter (6).Torch assembly (1) mainly is that the waste gas with oil plant, chemical plant is delivered to the high-altitude, passes through torch burning then and scavenging, reaches the purpose of environment purification.Device in Gas conduit (2) mainly is that Device in Gas is delivered to the top, torch is used so that ignite, its side and should be less than 1 meter apart from torch assembly, its height should be lower than in 1 meter of the Cauldron, material is generally selected stainless steel for use, diameter is the 10-30 millimeter, on the section of a pipe of Device in Gas conduit upper end, have some ventholes (11), the length of this section pipe is generally in 2 meters, particularly at the tip of distance ignitor (3) 25 millimeters have fire hole (9) with interior place, so that light Device in Gas, the aperture of venthole and fire hole should be less than 10 millimeters.High pressure generator (4) is installed on the platforms beyond 30 meters of the flare tips, and torch assembly generally has 6-8 platform, mainly climbs in order to keep in repair to make things convenient for and be provided with.It mainly is for fear of damaging because of the torch hyperthermia radiation that high pressure generator is installed in apart from flare tip position far away, the conspectus of high pressure generator (4) as shown in Figure 3, draw an earth connection at the center of inferior polar curve bag (16) in the transformer lines, form the two-way high pressure like this, be shown as between the AB in the drawings and all can form high-tension circuit between the BC and produce electrical discharge arc, as a short out road or when damaging, but another road operate as normal does not still influence igniting and normally carries out.Anti-airduct (5) covers on Device in Gas conduit (2) outside that has venthole, material is generally selected corrosion resistant plate for use, diameter is in 100 millimeters, but should be greater than Device in Gas conduit (2), length is generally 2-3 rice, has some air admission holes (10) on the tube wall, the air admission hole aperture is less than 10 millimeters, mainly be for replenishing the air in the anti-airduct (5), being beneficial to the burning of Device in Gas, fixing between anti-airduct (5) and the Device in Gas conduit (2) with support (12).Igniter (6) is mainly by waterproof case (7), ignitor (3) and high insulator (8) are formed, this device is arranged on nearest first platform (14) of Cauldron, approximately apart from about 10 meters of Cauldrons, avoided the danger of hanging operation on flare tip, also be convenient to maintenance, waterproof case (7) adopts stainless steel to make, high insulator (8) adopts the mica ceramics material, has high insulating property, and can tolerate high temperature, insulator (8) is installed between waterproof case (7) and the ignitor (3), can not make moist on the one hand, makes ignitor keep high insulation over the ground on the other hand, still can light Device in Gas on rainy day, in addition, the most advanced and sophisticated position of ignitor (3) is installed in the anti-airduct (5), and with the distance of fire hole (9) less than 25 millimeters.

The soar operation principle of formula igniter of internal combustion is: when needs burn waste gas, can operate by control system (13), the console setting on the ground, easy to operate, open the valve of Device in Gas conduit (2), make Device in Gas be transported to the top of conduit, make high pressure generator (4) produce high pressure again, through ignitor (3), locate discharge generation electric arc at fire hole (9), light Device in Gas, because fire hole place gas amount is little, a large amount of Device in Gas is upwards carried along pipeline (2), air is sent constantly in the anti-airduct (5) by air admission hole (10), makes Device in Gas locate burning at a plurality of ventholes (11), ignites the Cauldron until the top, this moment, waste gas was by leading to Cauldron in the torch assembly (1), the beginning burning process can stop to carry Device in Gas then, makes the Device in Gas burn-out in the anti-airduct (5), when burned waste gas finishes, Cauldron also extinguishes thereupon, has so just eliminated altar lamp, has saved a large amount of energy, when needing to burn waste gas again, can ignite the Cauldron easily.
