Background
In the field of municipal domestic waste incineration treatment, the reciprocating mechanical grate furnace is widely applied due to mature technology, stable and reliable operation, and can be divided into a reverse-pushing reciprocating mechanical grate furnace and a forward-pushing reciprocating mechanical grate furnace according to the relative direction of grate motion and waste movement (the waste moves from the front of the furnace to the back of the furnace).
The reverse-pushing reciprocating mechanical grate furnace has the advantages that the movement direction of the grate is opposite to the movement direction of garbage, the whole grate is inclined at a certain angle, grate segments are arranged in rows, the pushing heads are upward, and a plurality of movable grate segments and static grate segments are alternately overlapped. Due to the inclination and the reverse pushing action, in the process that the garbage moves backwards, the garbage at the bottom layer ascends, the garbage at the upper layer descends, and the garbage at the upper layer is continuously overturned and stirred to be fully contacted with air, so that the complete combustion of the garbage is realized. Because the reverse-push fire grate has the function of continuously turning and stirring the garbage, the falling and rolling of the garbage are realized without using a height section difference, and the whole hearth is on the same plane and has no steps.
In the structure of the reverse pushing fire grate, in order to meet the requirement that the movable fire grate pieces can integrally and consistently reciprocate, a plurality of movable fire grate pieces are integrally fixed on a movable mechanism, hydraulic driving is adopted, and the movable fire grate pieces are driven to do reciprocating linear motion on the static fire grate pieces by converting pushing or pulling of a hydraulic cylinder into reciprocating motion of the mechanism, so that the mechanism is called as a driving device of the fire grate.
The driving device of the step-difference-free reverse pushing fire grate meets the basic requirements of pushing the garbage to move, turn and the like in the combustion process, and also needs to meet the requirement of the burning rate of the garbage incineration. Therefore, the driving device for reversely pushing the fire grate adopts front and rear two-section driving, the front section drives and drives a plurality of rows of movable fire grate segments at the front part of the fire grate to move, the rear section drives and drives a plurality of rows of fire grate segments at the rear part of the fire grate to move, and the movement speeds of the front and rear fire grates can be accurately controlled in a sectional manner. When the garbage is ignited and burns forward, the movement speed driven by the front section is accelerated, the garbage burnt on the front grate is pushed to the rear grate as soon as possible, and the movement speed driven by the rear section is slowed down, so that the backward movement of the garbage is realized; on the contrary, when the garbage is burnt to the back, the moving speed driven by the front section needs to be slowed down, the flame moves forwards, and the sectional control can fully ensure the burning effect of the garbage incineration and the burning-out effect of the garbage.
