Description

Inflammable Solid Waste Incinerator And Incineration Fever Boiler}

The present invention relates to a method for maximizing the heat recovery and the apparatus that is completely burned by mixing and burning the combustible solid waste distillation incineration and direct incineration. It is easy to supply fuel because it supplies a large amount at one time, but it takes much time for the furnace to heat up and cool down to process it with a lot of combustible residue after combustion, and it takes a lot of trouble to take it out by humans. High pressures are generated in the furnace, which may cause safety accidents. In the direct incinerator, combustible solid waste is automatically converted into a modified fuel such as crushing, compression, and heating, and is automatically supplied to the incinerator. Continuous incineration by batch Method and incineration after batch input every time, the continuous incineration method by batch is difficult to employ due to excessive input equipment cost.By incineration method by batch, fuel is put into the fuel container every time and oil is sprayed and ignited into the fuel, resulting in frequent ignition. Incomplete combustion gas is leaked to the outside and there is a possibility of pollution, and the trouble of having to empty the incineration ash every time also burdens the operator.

In the conventional flue-pipe type heat exchanger, the oil-use heat exchanger has a large volume and associated cross-sectional area at the explosion site of the internal fire. In the heat exchanger using waste incineration heat, research was conducted and carried out on the removal and incineration of the combustion chamber. However, in the recovery of heat, the technology cannot be improved and the heat must be recovered immediately when a fire explosion occurs. This secondary combustion chamber is consumed largely, and consumes heat everywhere, such as disturbing and bending the flow of fire, and increasing the diameter of the pipe, so that the heat recovery efficiency of the heat exchanger is extremely low, reaching 50% or less. Is a waste of All

Therefore, the present invention is to solve the problems as described above, in the incineration method of combustible solid waste and incineration heat recovery, it is possible to automatically supply the incineration of the combustible solid waste without modification and incinerated and burned completely in a smaller volume than other incinerators The aim is to get a device that can burn the same amount while eliminating waste, minimize incineration residues, release and collect incineration ash, and recover the heat generated during combustion.

In order to achieve the above object, the fuel tank consists of a hopper and a hydraulic cylinder, and the fuel tank is bent by 90 degrees. The combustion chamber is formed and the combustion chamber wall is separated from the heat by the refractory heat insulating material, and the incineration ash descending passage on the inside and outside of the combustion chamber wall and the blower air supply passage on the outside are composed of cylindrical iron plates. Compared to this, a vertically connected heat exchanger with a small cross-sectional area and a small outside pipe is attached, and a blower is provided separately to supply air to each combustion chamber.

Specifically, the fuel tank includes a hydraulic cylinder and a pressure plate that maintains a constant pressure with the hopper, and the cylinder of the plate is less than the cylinder of the fuel tank to facilitate the forward and backward movement of the plate and made of stainless pipe attached downward to the upper part of the primary combustion chamber. The lower fuel of the primary combustion air supply means, which also serves as the fuel capping device, is automatically supplied as much as the amount of combustion.

Some of the primary combustion air is attached to the upper part of the primary combustion air supply means while supplying it to the outside of the lower fuel surface while rotating, and some of the primary nozzle air supply means forms an air nozzle port on the upper fuel limiting device of the primary combustion air supply means. It rotates in the same direction as the inflow direction and feeds to the center of the fuel surface to rapidly diffused combustion reactions throughout the fuel surface to generate incomplete combustion gas, unburned dust, and flames to fill the primary combustion chamber to form pressure. Air from the primary combustion blower is supplied from the primary combustion air inlet to the air nozzle opening and the air nozzle through the fuel capping device, and made of stainless steel.The primary combustion air supply means is protected from heat. Secondary combustion air supply means with a built-in air dispersion tank and finished with fireproof material on the outside. Secondary combustion air inlet is preheated in the air distribution tank of secondary combustion air supply means, and hundreds of air outlets are formed. Secondary combustion inlet air outlet has incomplete combustion gas, unburned dust, flame It is configured to disperse injection at right angles to the air outlet. The air outlet at the bottom of the secondary combustion chamber disperses secondary combustion air into incomplete combustion gas, unburned dust, and flame that flows into the secondary combustion chamber, and rotates in the same direction as the rotation direction in the primary combustion chamber. It is completely mixed with incomplete combustion gas, unburned dust, and flame introduced from the primary combustion chamber so that it is completely burned. Thus, the volume of the secondary combustion chamber is composed of two thirds of the volume of other incinerators. To match the incineration of other incinerators and the explosion of fire Could be done within

Because the rotation is made in the secondary combustion chamber, the completely burned dust is discharged to the incineration outlet installed above the secondary combustion chamber and stored in the incineration storage space.

In the upper part of the secondary combustion chamber, it consists of a vertically-connected heat exchanger that has a furnace that is available only as a fire passage and has a smaller cross-sectional area than the existing heat exchanger, and a smaller outer connection, and a completely burned fire column is disturbed or warped When a vertically connected heat exchanger is reached, it is possible to recover heat momentarily when a very rapid temperature rise occurs due to a fire explosion in a small inner furnace and a small cross-section.

When the fuel is widened to fill the hopper (5) and the hydraulic cylinder (1) and the plate (3) are advanced, some of the fuel enters the back of the plate (3) but is configured to flow out when the plate (3) is reversed. The right side of the fuel container 6 is bent 90 degrees to the upper side so as to be connected to the primary combustion chamber 9.

The primary and secondary combustion chambers are divided into secondary combustion air supply means in which the secondary combustion air dispersing cylinder (13) is embedded and finished with refractory materials on the outside, and composed of primary combustion chambers (9) at the bottom and primary combustion chambers (9) before and after both sides. The burnout inspection window 30 was configured, and on the right side, the ignition machine 33 was formed, and the primary combustion air supply means (Fig. 14) was attached downward on the upper part of the primary combustion chamber 9, and the primary combustion air was supplied with the primary combustion air. Attaching the air nozzle 16 to the upper part of the means (Fig. 14), it rotates to the bottom and supplies the fuel to the outside of the fuel surface 10, and inside the lower fuel capping device 11 of the primary combustion air supply means (Fig. 14). A sphere 35 is formed so that air is supplied to the center portion of the fuel surface 10 in the same direction as the air flowing from the upper portion so as to diffuse throughout the fuel surface 10, and the air is generated in the primary combustion blower 12. Through the combustion chamber air inlet 12-1 and through the fuel capping device 11, the air nozzle 16 is introduced and made of stainless steel so that the primary combustion air supply means (Fig. 14) is protected from heat. The secondary combustion chamber 19 is formed on the supply means (Fig. 15). The secondary combustion blower (17) generates air, preheats secondary combustion air in the air distribution tank (13) of the secondary combustion air supply means (FIG. 15), and forms hundreds of air outlets (15) for the secondary combustion chamber inlet ( The air discharge port 15 of 14) is configured to disperse the secondary combustion air into the incomplete combustion gas, the unburned dust, and the flame at right angles to the primary combustion chamber 9, and the air discharge port 15 below the secondary combustion chamber 19. The secondary combustion air is injected into the secondary combustion chamber (19) incomplete combustion gas, unburned dust, flame and diagonally introduced into the secondary combustion chamber (19) and rotated to match the rotational direction in the primary combustion chamber (9) to be completely mixed. The volume of the combustion chamber 19 consisted of two thirds of the volume of the other incinerators. The secondary combustion chamber 19 was accompanied by a furnace 34, which was made available only as a fire passage on the top of the exhaust port 32, The solution consists of a vertically-connected heat exchanger with a very small central cross-section and a small outer cross-section, and when the burned flame reaches the vertically-connected heat exchanger without disturbing or bending, the low-volume furnace (34) is associated with a small cross-sectional area. It is designed to recover heat instantaneously when fire explodes inside and causes a very rapid temperature rise.

As shown in FIG. 5, the combustible solid waste (hereinafter referred to as fuel) is placed in the hopper 5 and hydraulically loaded (1). The fuel plate 3 is advanced to the primary combustion chamber 9 along the fuel container 6.

The fuel injected into the primary combustion chamber (9) is ignited by the ignition device (33) and the primary combustion blower (12) is operated so that the air passes through the primary combustion chamber air inlet (12-1) and the primary combustion air. The fuel capping device 11 of the supply means (Fig. 14) is protected from heat and preheated, and the preheated air is rotated downward in the air nozzle 16 and supplied to the outside of the fuel surface 10, and the air supply means for primary combustion ( An air nozzle opening 35 is formed inside the lower fuel capping device 11 of FIG.
