A kind of low-voltage acidity gas integral combustor for sulfur recovery acid-making process, its institute Corresponding one of each acid gas arm stated checks hole, and acid gas endless tube is welded on cylinder, then passes through iron plate Weld together with ventilation terminal.
A kind of low-voltage acidity gas integral combustor for sulfur recovery acid-making process, its edge Acid gas endless tube uniform 4~8 the acid gas arms of circumference.
A kind of low-voltage acidity gas integral combustor for sulfur recovery acid-making process, its institute Stating the combustor of cylinder to be built by laying bricks or stones by lining and form, global shape is that taper adds a bit of cylinder;Lining divides For two-layer, respectively thermal insulation layer and flame retardant coating, use the form of pouring material, fix by anchor studs, corresponding Multiple acid gas arms open the through hole of respective numbers.
A kind of low-voltage acidity gas integral combustor for sulfur recovery acid-making process, its institute The burner stated is connected with body of heater by mounting flange.
A kind of low-voltage acidity gas integral combustor for sulfur recovery acid-making process, its institute One sewage draining exit is arranged at the burner bottom stated.
Effect of the invention is that: the present invention is directed to the insufficient problem of burning of low-voltage acidity gas and avoid Design and Machining sour gas entrance on incinerator, designs the simple installation of a kind of integration, operates steadily, fires Burn efficient low-voltage acidity gas burner.Burner of the present invention simplifies low pressure acid from overall structure types The intake method of gas, sour gas acid gas import from burner enters combustor and carries out blending burning, makes The structure obtaining whole acid gas incinerator simplifies, and eliminates design and the processing of sour gas import on incinerator. Analyzed by aerodynamic flow field, the shape of designed combustion room, optimize the angle of gun barrel on acid gas ring rifle And jet velocity, it is ensured that sour gas spray into the flame both not interfering with center rifle, also enhance acidity Gas and the blending of high-temperature flue gas and decomposition.Add the center rifle of an acid gas in burner center simultaneously, On corresponding pipeline, a ball valve is set, can suitably adjust ball valve aperture according to the load of sour gas, To ensure the flame rigidity of acid gas endless tube, add the sour gas Load Regulation of burner the most on the whole Ratio.When sour gas calorific value is higher, it is not necessary to when fuel gas is combustion-supporting, after closing fuel gas, flame of centre Position is filled by sour gas flame, in order to flame detector detects, it is to avoid conventional project is due to fuel gas Cutting off, sour gas all enters from the arm of the acid gas ring rifle of postmedian, and combustor does not has flame of centre, from And flame detector detection flame difficulty, cause the failure problems of parking.Each sour gas arm arranges inspection Look into hole, in case acid gas pipeline being checked whether blocking when maintenance, it is simple to inspection operation.Sewage draining exit Setting be easy to remove the dirt in burner.
