Description

Sludge Incineration System {Apparatus to iacinerate sludge}

The present invention relates to a sludge incineration treatment apparatus.

 The present invention is to improve the drying and firing efficiency of the sludge by configuring the thermal contact portion of the sludge supplied by the heating structure of the upper feed type to the structure of the upper and lower narrowing to extend the transport distance of the sludge. .

As is known, the recent pollution caused by environmental pollution has been realized, and various pollution prevention measures have been suggested.

 Conventional industrial and general waste incinerators do not have a separate continuous facilitating device in the incineration chamber, so the grate of castings installed on the bottom of the incinerator is installed to burn waste thereon. When it is thrown, it is dropped on the grate and accumulated.

 Therefore, the oxygen supply is not sufficiently supplied to the inside of the sludge, so it is not completely burned, and even though a separate oxygen supply device is considered in the grate structure, the air sprayer is frequently clogged because garbage is frequently accumulated, and incomplete combustion is proposed. have.

 For the purpose of solving the above-mentioned problems, a bearing is placed on the center of a plurality of support hole engines for general and industrial waste incineration, and the air plate arms are radially disposed along the circumference at regular angle intervals. Rotor is installed to protrude and is installed to fill the incineration space of cylindrical incineration chamber so that it can be rotated magnetically by partial output of indented air. An incinerator has been proposed to completely burn waste by dispersing it finely to achieve miniaturization of the incinerator, which is a basic condition of uniform incineration.

However, although the incinerator is a top-supply type but has a cylindrical structure, it is possible to expect a slight increase in the incineration efficiency by discharging the waste into the inside of the incinerator and supplying it finely. It is not suitable for the case, but is only to carry out the pretreatment process for incineration.

 For reference, briefly look at the conventional treatment of sewage sludge. First, the water content of the sludge from which 25% of water was removed through the dehydration process of the sewage treatment plant was dehydrated to about 10-20% by the dehydration process. After the transfer to the dryer to dry it, the conventional incinerator is large in size compared to the incineration efficiency, sludge flakes and drying conditions as well as sludge due to the lack of its own internal transport means There is also a structurally unreasonable problem in supplying and discharging.

In addition, since the sludge of the sewage treatment plant contains a large amount of polymer flocculant, the conventional dehydration drying method can not significantly reduce the sludge, and even during incineration treatment, the incineration method has an excessive cost of equipment and operating costs.

 In particular, during sludge incineration, dioxin or sludge dust, which is one of the factors of air pollution, is discharged directly to the outside of the incineration plant without filtration, resulting in secondary environmental pollution. Done.

 On the other hand, some incinerators with conveyor systems are provided, but since many conveyors must be constructed inside the incinerator with excessive burden of facility cost, it is difficult to secure space as well as the appearance of the incinerator is increased. Since there is a problem that the efficiency is lowered, the situation is required to improve.

The present invention intends to further improve the drying and firing efficiency of the sludge by configuring the thermal contact portion of the sludge supplied by the heating structure of the upper feed type to the structure of the upper and lower narrowing so as to extend the conveying distance of the sludge.

A sludge incineration device, comprising: a sludge conveying space part for downward movement of the sludge and a sludge conveying space part installed at the bottom of the sludge conveying space part, and a conveyor for external discharge of the sludge discharged below the sludge conveying space part. It is an aim to achieve the above object by providing a series of related arrangements.

 In the present invention, the incinerator main body 10 is coupled to a bearing 84 of an upper support 80 and a support shaft 85 fixedly fixed to the ground, and is rotatably built up, and a belt 83 is coupled to an upper end thereof. The pulley 82 is coupled to one side of the drive shaft 81 is interlocked by the drive of one motor and the exhaust port 62 is in communication with one side and the other side to supply the recovery heat back to the recovery heat inlet 71 Each of the heat recovery devices 74 connected to each other, a bottom plate 70 formed at a lower half of the drive shaft 81 and having a plurality of recovery heat injection holes formed thereon, a burner 100 formed on the top surface of the bottom plate, and an exhaust port 62, respectively. One side is in communication with each other and the other side is connected to each other so that the recovery heat is supplied to the recovery heat inlet 71 and the other side is connected to the upper surface of the bottom plate 70 and exhaust gas is discharged to both sides of the outer circumference. Exhaust port 62 is formed and the lead is provided with a heating space 61 inside 60 and the inner side of the support shaft 81 is rotated and rotated, and a plurality of through holes 32 and a transfer screw 31 are spirally installed around the top surface and a sludge inlet 51 is formed in the upper center. The sludge conveyance cover 30 having an empty top shape is connected to the drive shaft 81 and the support bracket 22 on the inner side, and is coupled to the inner side of the sludge conveyance cover 30 by the spacing retainer 21. Heat loss prevention cover 20 which rotates simultaneously with the sludge conveyance cover 30 together with the rotation of the drive shaft 81, and a duct for discharging the steam and odor of the sludge is installed on the top of the heat loss prevention cover 30 90 and the sludge conveyance cover 30 are installed to be spaced apart from each other, and are provided between the support cover 40 and the sludge conveyance cover 30 and the support cover 40 to downwardly move the supplied sludge. Sludge transfer space 50 for the sludge, and is installed on the bottom of the sludge transfer space 50 and the sludge If the transfer space (50) is a structure consisting includes a conveyor 86 for the external discharge of the sludge discharged downward.

 According to the present invention, the sludge inlet formed on the outer periphery of the upper periphery is formed because each cover for downward guidance of the sludge is a sludge heating structure for effectively performing moisture-containing sludge drying and firing. When the sludge is supplied through the sludge, the sludge is naturally moved downwardly to the bottom by its own weight along the upper surface of the support cover 40 and at the same time, the support cover 40 is provided by the conveying screw 31 of the sludge conveying cover 30. After the entire upper surface is traversed, the water is collected in the bottom center and discharged naturally downward. At this time, as the heating heat supplied by the bottom burner 100 continuously heats the support cover 40, the moisture of the hydrous sludge is increased. It is gradually removed completely.

 The sludge conveying means has a top shape that is rotatably installed on the bottom plate 70 and the fixed shaft, that is, the structure of the upper light lower narrow, and is supplied to the heating space part 61 by burners 100 formed on the upper surface of the bottom plate 70, respectively. It is possible to prevent the heat loss of the heated heater as well as the overall heating of the sludge.

 The sludge conveying cover 30 of the present invention is supported on the outer circumference of the fixed shaft and the plurality of through holes 32 and the conveying screw 31 are installed in a spiral on the bottom of the upper surface and the sludge supplied to the upper sludge inlet 51 is in practice. The cover is not moved to the bottom and is supported by the rotation guide of the conveying screw 31 installed in the sludge conveying customer 30 in the sludge conveying space part 50 provided between the sludge conveying cover 30 and the support cover 40. The entire upper surface of 40) is circulated, and the sludge is collected and discharged to the center of the bottom in a state where the water of the sludge is completely removed by the heating heater by the bottom burner 100. Firing becomes possible.

 The heat loss prevention cover 20 is coupled to the inner space of the sludge conveyance cover 30 by the gap retaining hole 21 to be dried and rotated together with the sludge conveyance cover 30 at the same time as the drive shaft 81 is driven. Steam and odor of the generated water sludge is discharged to the passage between the heat loss prevention cover 20 through the through hole 32 of the sludge transport cover 30 is discharged to the upper duct 90 and the heat loss prevention cover ( 20) it is also possible to effectively prevent the external loss of the heating heater.

 At the bottom of the sludge transfer cover 30, the support cover 40 is installed in a state spaced apart from the sludge transfer cover 30, and is connected and fixed to the stack 60. The heating heat of the burner 100 is a heating space inside the stack 60. Since it is supplied to the part 61 to heat the entire bottom surface of the support cover 40 at a time, drying of the sludge is unbiased in any one part, and evenly the hydrous sludge supplied to the sludge transport space part 50 of the supplied sludge evenly. It is dried and fired.

 Meanwhile, the exhaust gas generated by heating of the burner 100 and remaining in the heating space 61 is discharged to the outside of the incinerator main body 10 once through the exhaust port 62 formed on the outer circumference of the stack 60 to be incinerated. The heat is recovered through the heat recovery device 74 installed outside the main body of the device 10, and is usefully used to re-supply the recovered heat inlet 71 or to dry the hydrous sludge transported to the outside again. Finished sludge is to be transported to the outside of the incinerator main body 10 through the conveyor 86 installed on the bottom of the sludge transfer space 50 is to be easily collected.

 Therefore, in the present invention, when the temperature is sufficiently increased after applying heat to the burner 100, water-containing sludge is introduced through the upper sludge inlet 51 of the sludge conveying cover 30, so that the sludge is in the sludge conveying space part. Support cover 40 by the screw screw spirally installed on the bottom surface of the sludge transport cover 30 in the process of moving downward through the sludge transport space 50 formed between the 50 and the support cover 40 Drying and firing of the hydrous sludge is effectively performed by circulating the entire upper surface of the bottom surface and simultaneously discharging the sludge by the heating heater of the bottom burner and then discharging it to the bottom conveyor 86.

 According to the present invention, the sludge supplied to the incinerator main body of the top structure narrowly narrowed downward from the upper periphery is guided downward by a feed screw installed in a spiral at the same time as the rotation is rotated, and at the same time heating of the sludge by the bottom burner is simultaneously performed. As a result, the drying and firing efficiency of the hydrous sludge is not only maximized, but also the sludge conveying distance or the incinerator can be manufactured in a small size.

 In addition, the present invention has the advantage that it is possible to reuse the exhaust gas as well as preventing air pollution because it can separate and discharge the steam and odor of the sludge separately from the exhaust gas.
