The present invention relates to a high-pressure air swing gasification burner, and more particularly to cooling the part of the housing of the gasification burner to minimize the flame in the combustion chamber in contact with the inner surface of the combustion chamber to further extend the life of the burner. A high pressure air swing gasifier burner is provided.

Generally, aqueous wastes such as sewage sludge and food waste contain a considerable amount of water due to the nature of the aqueous wastes.These methods of treating them include first contacting the wastewater treatment agent or activated sludge, After the dehydration sludge is made into 70 ~ 90% dehydration sludge through several steps such as dehydration, the sludge is incinerated again, landfilled by sea or land, or drained to a river or sea.

However, in the incineration treatment method as described above, a separate incinerator which is specially manufactured is required, and dehydration sludge, which is an incineration product, is still very high in water content, and therefore, a large amount of fuel for incineration of the incinerator is consumed, and in a large amount even after incineration. We had the problem of dealing with the remaining ash separately.

In addition, in the method of landfilling to land or sea surface, there is a problem that corrosion does not proceed due to bacteria in soil or seawater due to the additives added in the treatment process, and it is drained to sewage or sea. In the treatment method, a stream or sea is contaminated by the drained sludge which is drained, which is directly prohibited by the law.

Accordingly, as one of the methods for more efficiently treating a large amount of aqueous waste generated in one day, the recent dehydration treatment of aqueous wastes such as sewage, manure, domestic wastewater or industrial wastewater, It has been proposed to produce sludge waste, which means a highly concentrated sludge or sludge, to be smokeless and odorless without burning, and to separate the vaporized and dried solid components from the sludge waste in a short time.

Thus, in order to vaporize the sludge state containing 70 to 90% of moisture within a short time without lead-free odor, it is possible to vaporize the sludge state waste, which is quite high pressure and high temperature is instantaneously connected with the sludge state waste. One of the devices used is a gasification burner.

As such, the conventional gasification burner has a fuel supply pipe equipped with an injection nozzle, a combustion air supply pipe, an ignition plug, and a temperature sensor installed at one side of the combustion chamber inside the housing and is burned at about 1100 to 1500 ° C in the combustion chamber. The high heat burned to the other side is vaporized as it is dried and pulverized by instantaneous contact with the waste in the sludge state supplied at high pressure.

However, in the conventional gasification burner used as described above, as the combustion is performed at a considerably high temperature in the combustion chamber as described above, many defects occur in the cooling method for cooling it.

In other words, the conventional gasification burners adopt air cooling and water cooling. In the former case, a jacket-type air chamber is installed outside the combustion chamber. In this case, the flame in the combustion chamber is the housing of the combustion chamber. As the inner surface of the combustion chamber is in contact with the inner side of the combustion chamber, the temperature difference between the inner side of the combustion chamber and the outer side of the air chamber is increased so that the welding part for forming the air chamber is frequently damaged, so that the cooling of the gasification burner is not performed. There was a problem that is difficult to use.

In addition, even in the latter case, it is not suitable to cool about 1100 ~ 1500 ℃, which is a considerably high temperature as water, and also has a risk of blasting when the pressure in the circuit rises rapidly due to heating. Also had to meet the requirements to be designed to withstand the problem.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object is to cool the part of the housing of the gas burner and at the same time to minimize the flame in the combustion chamber in contact with the inner surface of the combustion chamber heat is transferred to the housing In addition to minimizing conduction, it is possible to minimize the discharge of heat in the combustion chamber to the outside and to more efficiently supply the combustion air according to the combustion.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic longitudinal cross-sectional view showing the present invention, Figure 2 is a schematic plan view of the main part according to FIG.

As shown, the sludge waste containing 70 to 90% of moisture is burned at about 1100 to 1500 ° C. in the combustion chamber, and the high temperature burned to the other side of the combustion chamber is discharged at a high pressure. Fuel supply pipe 130 equipped with an injection nozzle 132 in which fuel is injected into one side of the combustion chamber 120 inside the housing 110 to be dried, pulverized, and vaporized, and secondary air required for combustion. The combustion air supply pipe 140 to supply and the spark plug 150 to ignite by providing a spark to the fuel injected into the injection nozzle and the temperature sensing sensor for controlling the progress of combustion according to the temperature of the combustion chamber after combustion And a conventional gasification burner (100).

According to the present invention, the fuel supply pipe 130 and the combustion air supply pipe 140 of the gasification burner are doublely overlapped by a partition wall 12 formed inside the outer surface of one end of the housing 110 on which the gas supply burner is delivered to the housing of the combustion chamber. An air chamber part 10 mounted to form an air supply path 14 so as to preheat by partially absorbing high heat and thereby reducing the temperature of the housing;

An air vortex composed of a plurality of air ejection pipes 22 in which the ejected air is inclined in the same direction so as to be connected to the air supply path on the inner circumferential edge where the injection nozzle of the combustion chamber is located and ejected in the form of a vortex like a whirlwind. It shows having the part 20.

Accordingly, the combustion is elongated in the center of the combustion chamber as if the air is ejected in the form of whirlwind from the air ejection pipe of the air vortex to the outside of the flame generated during combustion in the combustion chamber in the housing. To make it happen.

In addition, the air ejected from the air vortex part in the form of a whirlpool, such as a whirlwind, is preheated primarily in the air supply path, thereby supplementing the insufficient combustion air together with the secondary combustion air supplied through the combustion air supply pipe. There is also a condition to play a role.

Therefore, the flame generated during combustion in the combustion chamber is wrapped in a vortex, such as a whirlwind, ejected from the air ejection tube of the air vortex part, so that the combustion is gathered in a long form in the center instead of close to the inner surface of the housing. As the heat conduction to the housing has a condition that can be minimized, a longer period of time can be used while minimizing damage to the housing.

On the other hand, the inner surface of the combustion chamber 120 is formed of a refractory material (120A) such as a ceramic having a characteristic that the thermal conductivity is made as slowly as possible, so that the heat generated in the combustion chamber by the air vortex portion is conducted to the housing as much as possible Prevents heat conduction secondary by the refractory material that forms the inner surface of the combustion chamber and prevents heat from being discharged to the outside. It will be provided with the conditions which can be performed.

It has shown that it has the vortex jet part 30 with which 32 was attached.

Accordingly, as the combustion air required for combustion in the combustion chamber is supplied in a vortex-like vortex form by the vortex plate of the vortex jetting unit, combustion of the jetted air and the fuel injected from the injection nozzle is more smoothly performed. In addition to increasing efficiency, the flame itself upon ignition can be combusted in the form of a whirlwind like a whirlwind.

Therefore, in addition to improving the combustion efficiency according to combustion, the flame is also concentrated in the center to minimize the transmission of the high temperature due to the flame to the outside of the combustion chamber.

It is desirable to make it possible.

In addition, the combustion air supply pipe is provided inside the end of the auxiliary combustion air supply pipe 40 with a second vortex jet part 45 equipped with a plurality of vortex plates 42 inclined in the same direction as the air jet pipe. By supplying air in the form of a whirlpool, such as whirlwind, the surface of the flame according to the combustion, such as the vortex jetting portion is formed to have a condition that can be further gathered to the center of the combustion chamber without the flame of the flame.

On the other hand, the auxiliary combustion air supply pipe 40 is connected to the air supply path 14 and the air supply pipe 48 of the air chamber portion, thereby supplying the air instead of a separate air supply to the auxiliary combustion air supply pipe. The primary preheated air can be supplied to the air vortex section and the auxiliary combustion air supply pipe through the furnace, thereby simplifying the structure and supplying the air more efficiently. will be.
