Definitions

  • the present disclosure relates to the technical field of gas mixing, for example, a flue gas mixing device and method.
  • the sintering flue gas circulation process refers to a sintering method in which a part of the heat carrier gas discharged from a sintering process is circulated to the trolley to use after the sintering igniter.
  • the sintering flue gas circulation process has proposed that in order to ensure quality of the sintered minerals during the flue gas circulation, it is necessary to ensure that the circulating flue gas contains sufficient oxygen. Therefore, in the process design, exhaust gas generated by an annular cooling machine is usually used to supplement oxygen content in the sintering flue gas.
  • FIG. 1 is a typical process flow diagram illustrating a flue gas circulation in the related art.
  • the equipment shown in FIG. 1 includes: an annular cooling machine 1', an annular cold circulation fan 11', a flue gas mixer 2', a flue gas sealing cover 31', a sintering machine 32', a dust collector 4', a sintering circulation fan 41', a main sintering fan 42', a desulfurization tower 5 ', a chimney 6' and pipelines that connects the equipment.
  • the working process of the sintering process, the sintering flue gas treatment process, and the flue gas circulation process are as follows.
  • Raw materials are sintered in the sintering machine 32', and the sintered hot ore discharged by the sintering machine 32' is cooled by the annular cooling machine 1' and then generates annular cold exhaust gas. And after being pressurized by the annular cold circulation fan 11', the annular cold exhaust gas enters the flue gas mixer 2' and passes through the flue gas sealing cover 31' located above the sintering machine 32' to enter the sintering machine 32', together with the circulation flue gas taken from the sintering machine 32' and pressurized by the sintering circulation fan 41'.
  • the flue gas (non-circulating flue gas) generated by the sintering machine 32' passes through the dust collector 4' and is sent to the desulfurization tower 5 'and the chimney 6' after being pressurized by the main sintering fan 42', and is finally discharged.
  • the annular cold circulation fan and the flue gas mixer jointly realize the mixing of the annular cold exhaust gas and the circulating flue gas, and supplement of air is mostly realized by arranging a vent valve on the flue gas sealing cover.
  • the flue gas mixing device in the related art has the following problems.
  • problems such as air flow deflection and vortexing, flue abrasion, dust accumulation and poor mixing effect, and even air flow back suction during the mixing of the two air flows, resulting in working conditions and accidents such as stall, instability and increased vibration of the flue gas circulating fan; and a mixing device with a multi-mixing cavity and a mixing device with a reducing mixing barrel may fully mix the flue gas, but neither is suitable for the flue gas with large dust content.
  • a low-resistance flue gas mixing device that may easily adjust the composition of the flue gas and the temperature of the flue gas, stabilize the flow rate of the flue gas, avoid dust accumulation in the flue and abrasion of the flue, and protect the fan and auxiliary flues and other equipment is of great significance to the stable and efficient operation of the gas circulation process.
  • the flue gas circulation process directly supplements air from the sealing cover. Due to the large space of the sealing cover, the gas in the sealing cover will be sucked into a sintering bed to participate in the combustion reaction within a relative short residence time. Therefore, the method has the problem of uneven mixing of oxygen in the circulating flue gas, that is, the oxygen content is higher in an area adjacent to the air inlet, and the oxygen content is lower in an area far from the air inlet (also known as a hypoxic dead zone), and the hypoxic dead zone is extremely detrimental to sintering production. Therefore, it is also the key to improve the stability of the flue gas circulation process to make the oxygen carried by the supplemented air mixed evenly in the circulating flue gas by reasonable technical means. Further relevant technologies are also known from CN105435669A , which relates to a Venturi mixer with drainage function and discloses a gas mixer according to the preamble of claim 1.

  • the annular cavity 3 extends outwardly to form an annular cold exhaust gas branch pipe 31, and each of the air inlet holes 221 is in communication with the annular cavity 3 and the annular cold exhaust gas branch pipe 31.
  • the annular cold exhaust gas branch pipe 31 is obliquely arranged on the annular cavity 3.
  • annular cold exhaust gas may enter the annular cavity 3 from the annular cold exhaust gas branch pipe 31, and then enter a flue gas main channel through the air inlet holes 221 evenly and obliquely distributed on the circumferential side wall of the throat section 22, thereby achieving a relatively uniform air intake throughout the throat section 22, buffering and stabilizing incoming flue gas, and making the annular cavity 3 and the flue gas main channel form a stable pressure difference, and maintaining a flow field of the flue gas main channel even and stable.

  • a diameter of the flue exit section 12 is greater than a diameter of the flue entrance section 11, and an ash hopper 13 is arranged at a bottom of the flue exit section 12, so as to collect part of the dust settled by gravity due to the increase of the pipe diameter and the decrease of the flow velocity after the mixed flue gas passing through the flaring section 23, thereby effectively avoiding the ash accumulation in the flue and abrasion of the flue.
