Abstract
The utility model relates to a direct electric ignition device for an air flow bed gasification furnace, which has a split-type structure and consists of two parts including a plasma generator and an electrode group; electrodes and an arc release end are covered by insulation ceramic rings; a discharge end of the arc release end is an exposed tip; the arc release end takes on an 'L' shape; and the upper end of the vertical part of the arc release end is connected with the lower ends of the electrodes by screw thread. The direct electric ignition device is reformed on the basis of the original technical burner, and the structures of the burner and the gasification furnace are not needed to be changed, so that the ignition efficiency is improved on the one hand, and the using cost is reduced on the other hand.
Description
Technical field
The utility model proposes a kind of igniter that the direct-fire of chemical industry stove is used that is used for.The device that particularly relates to the direct firing coal-dust of a kind of powder coal gasification furnace.
Background technology
Along with the every continuous advancement in technology of chemical industry stove, the gasification furnace sparking mode also develops towards safer, environmental protection, economic direction thereupon.Plasma is to be heated to excessive temperature and by the gas of height electric power, to have high heat, and joining, auxiliary air can form the high heat plasma arc.Can be widely used in the starting ignition of various imflammable gas devices and various gas fuel industry stove and accessory, be the desirable igniter of industrial furnace.The ignition method of prior art mostly is classification or the substep methods of printing is promptly lighted combustible gas earlier by igniter, ignites after combustible gas is stable or by accumulation of heat ignite fine coal or coal slurry again.The numerous and jumbled destabilizing factor of system is many in the practical application, and a certain medium or valve occur unusually in the cold hearth ignition process, can cause that all system's jumping car causes loss of ignition; Undesirable or accumulation of heat also will cause the repetition accumulation of heat to the hot wall stove inadequately because of the temperature rise of operating personnel's misoperation system; And the different medium of plurality of specifications coexistence can the construction investment of increase initial stage, also can bring inconvenience to the maintenance, repair in system's later stage.
Summary of the invention
The purpose of this utility model is to provide the high airflow bed gasification furnace of a kind of ignition success rate direct electrically-fired device.
The direct electric ignition device of a kind of airflow bed gasification furnace, igniter is a split-type structural, is made up of two parts; A part is a plasma generator, and another part is the electrode group; It is characterized in that: the electrode group is two electrodes of symmetry, and electrode one end is connected with puts the arc end, and the electrode other end is electrically connected with plasma generator by connecting line, and plasma generator is connected with power supply by high-tension cable; Electrode and to put arc end inner core be red copper; Electrode and put the arc end and wrap up by the insulation porcelain ring; The discharge end head of putting the arc end is exposed tip; Put the arc end and be " L " shape, the vertical part upper end of putting the arc end is threaded with the electrode lower end, and the discharge end head is given prominence to the about 5～10cm of process burner.
The above-mentioned direct electric ignition device of a kind of airflow bed gasification furnace is characterized in that: the electrode that one connects and put the arc end and fixed by the process burner flange connecting hole on top and the head retainer ring of bottom respectively.
The above-mentioned direct electric ignition device of a kind of airflow bed gasification furnace is characterized in that: two electrode bottoms are for alternately coiling shape, and the twisting of electrode section is positioned at process burner head and technology cooling coil relevant position, and the twisting of electrode section is positioned at the technology cooling coil outside.
During use, adopt direct current or alternating current as power supply, use plasma generator low-voltage is risen to positive high voltage and negative high voltage by booster circuit, the plasma (orifice) gas that utilizes the formation of positive high voltage and negative high voltage ionized gas is directly ignite coal dust or a coal slurry of plasma torch that temperature can reach 3000～10000K.
Advantage of the present utility model:
1, the powerful thermal source that utilizes plasma gas to provide directly makes coal dust generation chemical reaction firing coal-dust or coal slurry.
