Definitions
- all the furnaces in the furnace are made of a push-type grate.
- the grate stroke realizes the looseness and turnover of the garbage, and the garbage conveyed forward is in full contact with the air. Achieve complete combustion of the garbage.
- the problems are as follows: First, in order to ensure the residence time of the garbage in the furnace, the grate area is designed to be larger, or the grate stroke design is larger, the height or length of the incinerator is increased, and the cost is increased; second, the grate and The movement direction of the garbage layer is the same.
- the design of the area of the grate is larger, or the design of the grate is larger, the height or length of the incinerator is increased, and the cost is increased;
- the moving grate and the garbage layer move in the same direction.
- the garbage layer is high, the adjacent grate is relatively low in relative drop or the relative stroke is small, the running garbage is almost in a relatively static state, and it is stirred and mixed. The effect is poor, the garbage is not dry enough, the combustion cannot be fully burned, the combustion efficiency is low, and it is difficult to achieve the index of the ash slag burning rate;
- the leachate in the garbage layer will be pushed forward by the push grate before it evaporates, increasing the drying time of the garbage, the leachate is not collected in time, and the residence time of the garbage in the whole furnace is increased, all in the furnace. Evaporation into water vapor, increasing the moisture content of the flue gas, affecting the incineration process;
- small incinerators consisting of single or double (two) grate systems and other equipment can be used, combined with small incinerator process control to effectively achieve waste incineration. Treatment, to reduce, resource, this kind of incinerator is called “low-order" grate incinerator.
- large incinerators consisting of three rows, four columns... grate system and other equipment can be used. Also combined with large incinerator process control, waste incineration treatment can be effectively realized, and reduction and resources can be realized.
- Chemical known as the "high-order" grate incinerator.
- the heads of each of the grate pieces are provided with fins, and the fins of all the grate pieces of the step are formed into a laterally arranged tooth-like matrix structure.
- the "high-order" grate system of the incinerator adopts the side rocker drive, the front rocker drive and the front direct drive in the driving mode of the grate; the reverse grate drive can be driven by the front rocker and the front drive.
- the side rocker drive version can only be used for the outermost two rows of grate.
- the tie rod is linear or "Z” shaped; the fixed beam is "M” or "back”.
- Figure 4 is a second structural view of the cross section of Figure 2 B-B.
- Figure 8 is a cross-sectional view taken along line E-E of Figure 2;
- the minimum number of wind chambers to ensure the process requirements is 4, which can meet the technical parameters such as primary air volume, air temperature and wind pressure; the number of wind chambers reaches 6, which can better control the primary air parameters of the grate, which is more conducive to The incineration process can better achieve the incineration effect of the entire waste layer.
- the slewing section grate comprises a side beam 1, a fixed beam 2, a fixed grate piece 3, a movable beam 4, a movable grate piece 5, a push-pull rod 24, a roller device and a front rocker driving mechanism.
- a fixed beam 2 and a movable beam 4 are arranged between the side beams 1 on the left and right sides, and the fixed beam 2 is in the shape of "M" or "back".
- the movable beam 4 of the screed section of the grate is equipped with the right and left push-pull rods 24 arranged side by side, and the push-pull rod 24 is linear or ""
- the Z"-shaped, left and right push-pull rods 24 pass through the fixed beam 2 and are driven by the front rocker drive mechanism.
- the left and right push-pull rods 24 are coupled to the movable beam 4 as a tie rod holder, and the left and right forward push-pull rods 24 are supported by at least two roller devices.
- the movable grate plate and the fixed grate plate are overlapped before and after, and are arranged in series to form a reverse pusher grate.
- a wedge groove is formed between the side wall 1 of the reverse pusher grate, the side of the grate row and the outer steel of the furnace body 27, the wedge groove is filled with a refractory sealing filler 29, and the notch of the wedge groove It is sealed by a "U" shaped buffer thermal expansion platen 31 (see Fig. 10) or by a corrugated buffered thermal expansion platen 32 (see Fig. 11).
- the movable beam 4 of the reverse pusher grate is equipped with a reverse push rod 25 arranged side by side, and the reverse push rod 25 is a straight type or a "Z" shape, left and right.
- the push-pull rod 25 passes through the fixed beam 2 and is driven by the side rocker drive mechanism.
- the left and right reverse push-pull rods 25 are coupled to the movable beam 4 as a tie rod holder, and the left and right reverse push-pull rods 25 are supported by a plurality of roller devices.
- the structure and arrangement of the roller device are the same as those of the swaying section, and will not be described herein.
