Description
The present invention relates to a horizontal transfer multi-stage combustion-promoted water-cooled grate device for facilitating speed control of a driving part for advancing and retracting a plurality of fluidization grid arrays according to a position of a combustion chamber.
Generally, the incineration plant includes a plurality of fixed grate arrangements and a plurality of fluidization grid arrays arranged alternately in a stepwise manner so that incineration is performed while the waste is continuously moved.
In the incineration plant, there is a lot of residue in the facility due to the foreign matter and high temperature generated by incineration of the waste in the image. In addition, the fixed grate arrangement and the fluidization grid array which are alternately arranged in a stepwise manner may be distorted due to high temperature.
As described above, the image continuous acceleration driving devices installed in the incineration facilities so far are contaminated by high temperature and various foreign substances, resulting in a small equipment failure, resulting in difficulty in maintenance and high cost. Also, since the driving device for moving the plurality of fluidization grid arrays forward and rearward has a complicated structure, maintenance and repair of the equipment has been difficult.
In order to solve the above problems, Korean Patent Registration No. 10-0632248 filed by the applicant of the present invention and filed by the present applicant (entitled "Linear Induction Rail, Image Continuous Promotion Driving Device by Continuous Cooling and Induction Rail Grate) Lt; / RTI >
In this patent, since the driving devices for driving the grate are installed outside the incineration combustion chamber, they are shut off from waste or high temperature, and there is no residual space, so that it is possible to operate the facility stably.
In actual operation, in the grate combustion chamber, the forward and backward speeds of the driving parts for moving forward and backward the plurality of fluidization grid arrays from the fuel inlet part located at one side of the combustion chamber to the re-discharge part located at the other side of the combustion chamber are required to be increased in combustion efficiency .
However, in the above-mentioned patent, since the hydraulic cylinder is used in the driving part for moving the plurality of fluidized-lattice arrays back and forth in the construction, the speed control of the driving part for moving the plurality of fluidized lattice arrays according to the position is difficult. In addition, since the hydraulic system is used, the apparatus is complicated, the reaction speed is slow, and the facility maintenance cost is large.
In addition, there is a problem that thermal deformation is likely to occur because there is no means for cooling the linear induction rails, the image continuous acceleration driving device by the minimum driving force, the continuous cooling and the induction rail grate.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a horizontal transfer multistage combustion promoting water cooling Thereby providing a grate device.
It is another object of the present invention to provide a horizontal transfer multistage combustion promoting water-cooled grate device for preventing thermal deformation of a fluidized lattice by circulating and cooling by water-cooling.

Unlike the conventional apparatus using a hydraulic cylinder, the horizontal transfer multi-stage combustion-promoted water-cooled grate apparatus of the present invention having the above-described structure moves the fluidized lattice back and forth by rotation of the motor, The maintenance cost can be reduced.
Further, unlike the conventional apparatus using a hydraulic cylinder, the fluidized lattice is moved forward and backward by the rotation of the motor, and the rotational speed of the motor can be controlled by using the inverter. Therefore, unlike the conventional apparatus using the hydraulic cylinder The speed control for moving the fluidization grid forward and backward can be facilitated.
In addition, it is possible to extend the lifetime of the apparatus by preventing the thermal deformation of the fluidized lattice and the fluidized lattice axis by circulating and cooling the fluidized liquid.
