Description

High temperature pyrolysis incinerator utilizing water tube grate}

The present invention relates to an incinerator for household waste, and more particularly, to a high-temperature pyrolysis incinerator facility using a water pipe burn.

The existing incinerators currently operating in some areas have several problems in terms of efficiency and operability.

First of all, the conventional incinerator is required to increase the secondary combustion chamber in order to increase the efficiency of the secondary combustion chamber 20a, and the manual input pusher plate 7a does not play a role in actual operation as well as the installation site. Even

Combustion air injection hole 40a is disposed only in the front of the incinerator, but in order to help smooth and efficient combustion, air injection from only one side is not appropriate, and the garbage dropped on the burn burns only the surface of the garbage bundle. And often the inside is not well burned.

The operability of the gate drive motor 61a for remnants necessary for carrying out the remnants from the temporary storage tank 14a is poor. In addition, in the water pipe type image, the lower image 72a and the upper image 73a are connected to each other between the right header 71a and the outlet header 74a to form a loop, and the role of the upper image 73a is Suspicious The ceiling of the combustion chamber is flat (80a) to resist the flow of flame and structurally weak, the flame-induced steel baffle (15a) is structurally weak and easily burned out, outflow from the waste temporary storage tank (1a) Since the leachate is to be discharged to the large storage tank or the leachate treatment plant through the discharge pipe (2a) is less practical.

The present invention for solving the above problems, it is an object of the present invention to provide a more efficient and operable life garbage incinerator facility by reasonably improving or supplementing each of the above-mentioned items.

According to a preferred embodiment of the present invention for achieving the above object, the garbage collected at the point of generation of various household waste is stored in the garbage temporary storage tank (1b), and some time passes. In connection with this, some waste leachate is generated, which accumulates in the waste leachate temporary storage tank 3b through the waste leachate discharge pipe 2b. On the other hand, if the heat generation amount of the waste put into the primary combustion chamber 13b is higher than the designed value, it is necessary to suppress the temperature in the primary combustion chamber 13b to maintain the efficiency of the incinerator. At this time, water is sprayed and adjusted in the primary combustion chamber 13b. At this time, if the waste leachate is secured in the temporary storage tank 3b, it is advantageous to use this leachate. The volume of the leachate temporary storage tank 3b can be empirically determined according to the characteristics of the local waste, and the leachate pressure pump 10b is automatically operated according to the level of the tank. The discharge amount discharged from the pressure feed pump 10b causes only the required amount to be ejected into the primary combustion chamber 13b through the leachate jet nozzle 8b.

When the household waste is put into the feed hopper 11b by the crane 4b, the waste falls to the water-cooled image 72b via the feed holes 12b by the feed pushers and the foot plates 5b and 6b. Here, the waste is burned, and the water-cooled waste stirrer 50b is operated to promote the waste. Cooling water always flows inside the tube of the stirrer 50b to maintain sufficient strength even at a high temperature of the combustion chamber 13b. In other words, this garbage stirrer 50b serves as a virtual poker. Thus, unburned exhaust gas is completely combusted in the secondary combustion chamber 20b to become exhaust gas at a high temperature (around 900 ° C), and the amount of heat required in the process of passing the associated waste heat boiler 16b through the high temperature waste gas discharge pipe 19b. After being absorbed, it is sent to subsequent equipment (air preheater, Scrubber, Bag-filter, Induced fan, stack, etc.) via the cooling waste gas (below 350 ℃) discharge pipe (18b).

High temperature incinerators around 900 ° C inevitably require a cooling system of the exhaust gas. When the household waste is incinerated normally, the temperature of the exhaust gas is around 900 ° C. If such hot gases are directly passed through various equipments installed in the back of the incinerator, corrosion of these equipments arises. In other words, combustion of household garbage generates corrosive gases such as SO _X , NO _X and HCl from some components of the waste to corrode metals. It is necessary to adjust the exhaust gas temperature of 900 ° C. in the range of 150 ° C. to 350 ° C. with the lowest corrosion degree.

In the present invention, it is preferable to also provide a dust removal device for removing the fine dust contained in the exhaust gas.

The present invention is to improve or supplement the conventional high-temperature pyrolysis waste incinerator, the details of the improvement point and method according to the following paragraph for the purpose of the generation of more efficient and easy to use incinerator.

Secondary combustion chamber (20a) of the conventional incinerator has a small volume, the efficiency of the secondary combustion chamber (20a) is not only low, but also poor constructionability during construction, the secondary combustion chamber 20b, by lowering the secondary combustion chamber bottom (21a) As shown in Fig. 2b), good results were obtained. Therefore, the bottom of the incinerator base is flat, as in the second combustion chamber floor 20b.

The manual injection footshoe 7a is intended to prevent the flame from flowing back to the feeder hopper 11a while the wastes are introduced into the feeder hopper 11a. There was no reverse flow even when driving on a dog alone. This is due to the fact that the combustion chamber maintains a suitable sub-rock by the induced fan at the rear of the incinerator. Therefore, it is preferable to remove the manually-inserted foot sharp 7a (FIG. 3a).

The air required in the primary combustion chamber 13a was supplied only to the air nozzles 40a (FIG. 4a) arranged on the front side of the primary combustion chamber 13a. The temperature distribution in the primary combustion chamber 13a was poor, and the air nozzles in front of the primary combustion chamber 13a were poor. The secondary combustion chamber air nozzles 43b are evenly disposed in the side surfaces 41b, the lower portion 42b, and the secondary combustion chamber 20b as well as 40b and 4b. Experienced.

Next, a poker, or stirrer, which burns the fire inside a common firewood is described in detail. When a large amount of water or rubbish is dropped into a pipe-type burn and burned, the surface of the rubbish can be burned smoothly, but the more difficult the combustion is, the more it enters the inside of the bag. It is well known that we have been using poker for a long time to promote combustion when this is the case at home. Since the same phenomenon occurs in the garbage combustion chamber, a poker, that is, a stirrer, is required to improve the combustion efficiency. However, since there is no conventional one, a good combustion efficiency is obtained by attaching a stirrer. The outer shape of the stirrer has a U-shape as shown in 50b of FIG. 5b and rotates the rotary shaft left and right at an angle of 90 degrees to 120 degrees to cope with the trash loaded on the image. A hydraulic cylinder is used as the power of the stirrer, and the stirrer itself is composed of a pipe, and the cooling water passes through the pipe to maintain the strength of the stirrer and increase its life.

The following is a device for lifting garbage from the garbage, that is, the door of the remnant tank. Conventionally, the door width 60a (FIG. 6A) and the counter weight 63a were connected with the cable 62a, and the cable 62a was operated with the electric motor 61a. However, due to frequent failures of the reducer, this is the hydraulic cylinder 61b (FIG. 6b) showed good performance.

Next, a water-cooled image is explained in full detail. Conventionally, an image is connected between an inflow header 71a (FIG. 7A) and an outflow header 74a by connecting the water-cooled upper image 73a and the water-cooled lower image 72a to each other, so that the space is effectively inside the cube. The reason for the existence of the water-cooled upper and lower burns is to increase the combustion efficiency by only burning the waste in the center of the combustion chamber 13a. The reason for the water-cooling is to increase the temperature of the burn itself to maintain the burn life and strength. It is kept below ℃. And it can be made well without the assistance of the water-cooled upper image (73a) to burn the waste pile is located above the water-cooled lower image (72a). Therefore, there was virtually no need for the water-cooled top image 73a, and it was removed and operated with only the water-cooled image 72b (Fig. 7B).

Next, the ceiling of the primary combustion chamber will be described. Conventional ceiling is composed of a plane (80a, Fig. 8a) is improved to the arcuate (80b, Fig. 8b) to improve the flow of the flame and light weight by increasing the efficiency in terms of structural and calorie.

Next, the flame induction baffle will be described. Conventionally, since the flame-induced baffle is constructed of steel baffles (15a, FIG. 9a), there is a closed end that needs to be repaired or replaced frequently due to a high temperature flame, thereby replacing it with a refractory brick (15b, 9b). This construction prevented these waste disposal stages.

Next, the waste leachate generated in the waste temporary storage tank 1a (FIG. 10A) is described. Conventionally, the leachate generated from the temporary storage tank 1a is collected in a large capacity tank located outside the incinerator through the leachate discharge pipe 2a, and then disposed of by enemy or connected to the municipal sewage treatment plant through the leachate discharge pipe 2a. I chose the option, which is both cumbersome. Therefore, in the present invention, in order to avoid this, the leachate flowing out of the leachate discharge pipe 2b, FIG. Is evaporated and vaporized into the primary combustion chamber 13b to lower the temperature in the primary combustion chamber 13b to smoothly operate the incinerator.

In fact, when operating a waste incinerator, the temperature in the combustion chamber is often higher than the design temperature, which often needs to be lowered. This temperature adjustment is usually carried out by spraying water, and waste leachate is used instead of this water. Since experience shows that the amount of leachate is not high and the amount of leachate is insufficient for temperature reduction, it is reasonable to dispose of leachate in this way. Of course, when the amount of leachate is insufficient for temperature reduction, water may be added to leachate and used.

The incinerator according to the present invention improves the efficiency of the secondary combustion chamber without changing the height of the incinerator itself or the size of the plane compared to the conventional incinerator, and simplifies the input pusher mechanism by eliminating the unnecessary manual input pusher plate. Helps to reduce Poor temperature distribution in the primary and secondary combustion chambers greatly improves the combustion efficiency by improving the arrangement of air nozzles, and improves the efficiency of the entire incinerator by eliminating the conventional combustion by attaching a very simple water-cooled stirrer, and burns the upper part of the cooling water. It has the advantage of reducing the manufacturing cost by eliminating and showing the advanced in the thermodynamic and structural aspects by arching the planar ceiling of the combustion chamber. Incineration of leachate from headaches also solves the problem of leachate toxic substances. In other words, the present invention has a great effect in terms of thermodynamic, structural, operability and economical.
