Technical field
The utility model relates to a kind of torch for gas combustion, specifically a kind of high-efficiency ground torch.
Background technology
Mainly be two kinds of closed ground torch and open-type ground flares in the present disclosed ground flare technology, all adopt a plurality of burners in these two kinds of technology, according to user's operating position as can be known, the injection diameter on the burner is generally 5～8 millimeters.Secondly, these burners are set up the employing horizontal layout at cloth, and use the form of fractional combustion, that is: after detecting torch gas pressure and be elevated to setting value by pressure detecting element, interlocking is opened secondary or three grades of burners burn.
In use there are the following problems for present technology:
1. the burner spray orifice is larger, is not easy to air and mixes, and has prolonged the tail-off time, causes having incomplete combustion, the problem that efficiency of combustion is low behind the flue gas discharge cylindrical shell;
2. to open the condition of other one-level burner be that torch gas pressure is elevated to setting value to the torch control system, for example automatically to open two stage burner be the setting value that torch gas pressure reaches two stage burner to control system, the condition that the two stage burner realization is caught fire is the naked light place that the gas of spray orifice ejection is diffused into the one-level burner, and this moment, one-level burner pressure was higher, move on the flame, therefore the gas diffusion height of two stage burner ejection will increase, the unreacted fuel gas scale of construction increases, when touching naked light deflagration phenomenon will occur, affect stability and the security of flare system;
3. many, the complex structure of burner parts, cost is high.
The utility model content
The purpose of this utility model is to provide a kind of high-efficiency ground torch, and this ground flare is conducive to abundant burning, low cost of manufacture.
The technical scheme in the invention for solving the technical problem is: a kind of high-efficiency ground torch, comprise cylindrical shell, flame-observing hole, burner, cylindricality basis and control section, described cylindrical shell is installed on the cylindricality basis, annular is distributed with a plurality of flame-observing holes on the sidewall of cylindrical shell, and burner is divided into multistage and is arranged in the inside of cylindrical shell.
Described burner comprises one-level burner, two stage burner and three grades of burners, and the layout of burner adopts " V " font to be arranged symmetrically with, and the centre is the one-level burner, outwards is arranged symmetrically with successively two stage burner and three grades of burners; Two stage burner is positioned at the top of one-level burner, and three grades of burners are positioned at the top of two stage burner, and the difference in height of adjacent two-stage combustion device is 0.1～0.3 meter.
Described burner comprises burner head, and the center of burner head is a five-way structure, and the bottom at five-way structure center is air inlet pipe, and four openings of all the other of five-way structure are equipped with arm, and described arm is connected with a rectangle coil pipe; Be provided with uniformly the slit on described arm and the rectangle coil pipe, described slit is interrupted and is arranged, and the width in slit is 0.4～1.0 millimeter, and the total length in slit is greater than half of arm and rectangular disk length of tube summation on each burner; The cross section of arm and rectangle coil pipe is ellipse, and oval major axis is the longitudinal axis, and described slit is located at the top of transverse.
The outside on described cylindricality basis is provided with windbreak.
The outside of described windbreak is provided with cat ladder.
The utility model compared with prior art has following outstanding beneficial effect:
1, owing to changing spray orifice into slit by circular hole, so that the contact area of torch gas and air increases, ensures the efficient burning of torch gas, solved the inadequate problem of burning.Take injection diameter as 6 millimeters and gap width as 0.5 millimeter calculating, the principle that equates in line with circulation area, the air area that touches at the torch gas of torch gas ejection place the utility model burner ejection is 6.05 times of circular hole.Secondly, change circular arm in the prior art into ellipse, reduce the pipe width, reduce the circulation of air resistance, more be conducive to abundant burning.
2, two stage burner and three grades of burners are lifted to suitable height after, so that one-level burner flame or two stage burner flame can be lighted torch gas timely when opening two stage burner or three grades of burners, prevent the generation of deflagration phenomenon, guarantee the safe and stable operation of flare system.
3, burner has adopted a five-way structure, four arms and a rectangle coil pipe, Laser cutting is adopted in the slit, need not to make non-standard, so that the price of burner greatly descends, as calculated, with the burner contrast of same discharge capacity, burner manufacturing cost of the present utility model only is 2/3rds of prior art.
