Definitions

  • the invention relates to a grate element for a grate a waste incineration plant with several in a row arranged rows of grate blocks.
  • Conventional inclined feed grates for Waste incinerators have rust elements with several rows of grate blocks arranged one behind the other, whereby a fixed row of movable grate blocks Row of rust blocks follows.
  • the movable rows of grate blocks are assigned to a grate car through which they go back and forth be moved (CH 585 372). The mixing and that The waste is stirred in the direction of transport.
  • a push-back grate is from the prior art known as described in a variety of patents is, for example in DE 525221 and DE 1099117.
  • Ein such a push-back grate is an inclined grate alternating fixed and movable rows of grate blocks.
  • the grate blocks of the movable grate block rows become the lower layers of waste to be incinerated
  • the beginning of the grate is pushed towards the top layers move towards the end of the grate. This will counteract the waste pushed the transport direction away, so that the waste on Beginning of rust piled up and gravity down is promoted, which is partly through uncontrolled Slipping happens.
  • EP 1 001 218 describes a water-cooled combustion grate described, which consists of a combination of a feed and a sliding grate, both of which are water-cooled Have grate plates, at least every second is designed to be movable.
  • a stair grate is exposed in the direction of transport several grate elements together, usually three until six grate elements are arranged one behind the other.
  • On Stair grating can consist of one to five grating tracks.
  • Each grate element has several, in the direction of transport rows of grate blocks arranged in steps on, the rows of grate blocks fixed or movable are.
  • a row of grate blocks is divided by several, for Example 16 to 30 rust blocks formed.
  • the rust blocks can be water or air cooled.
  • the grate blocks are hung next to each other on a block holder tube and clamped together using a tie rod.
  • everyone Rust block has a foot that is on the surface of the the subsequent grate block lies in the transport direction. When moving forward, the foot of the the surface of the rust block lying on it lying grate block in the direction of transport.
  • the object of the present invention is a grate element provide where the waste is intense and is continuously mixed and promotion takes place in a controlled manner.
  • a first part of the grate blocks is one movable row of grate blocks a first grate car assigned and a second part of the grate blocks is one assigned to second grate wagon, the inventive Grate element is equipped with two grate cars.
  • the mobility of the first Part of the grate blocks regardless of the mobility of the second part of the grate blocks.
  • By the independent mobility of the grate blocks results an additional side mixing. On the grate this creates mountains and sinks of waste, which alternately moved back and forth.
  • the first part of the grate blocks independent of the second part of the grate blocks is movable different operating modes possible. So it can Movement pattern of the grate element depending on the type of waste can be set differently.
  • the division of the individual grate blocks in width to the corresponding Grate wagons are advantageously made in grate block groups of five or seven rust blocks. A bigger or a smaller one Splitting or even splitting would also be conceivable.

  • the first and the second grate car is independent of each other Drive devices on.
  • the first and second grate wagons are mechanical has coupled opposite drive means.
  • Preferred drive devices are hydraulic, pneumatic or electric actuators. Especially a cylinder-piston unit is preferred.
  • the independent drive equipment is the controller of the two grate cars possible individually.
  • the first grate wagon two Drive devices and the second grate carriage one Has drive device. On the one hand, this enables that the first grate car (primary car) smaller Drive devices needed that are simple and enable quick replacement during operation.
  • the first grate car primary car
  • the drive devices on the first or the second grate wagon that is exerted on the grate element Forces evenly distributed.
  • the first and the second grate car clocked in reverse. It means that when the first grate carriage moves forward, the second grate wagon is moving backwards. In Another preferred embodiment is the first and the second grate wagon clocked equally, which means that the first and the second grate wagon over at the same time different movements are moved.
  • grate blocks Preferably have within the same row of grate blocks one to seven, particularly preferably three to five, rust blocks lying directly next to each other, the together form a grate block group, the same Direction of movement, i.e. they are the same rust wagon assigned. This makes an optimal one Mixing effect achieved.
