Description

High-efficient formula msw incineration boiler

Technical Field

The utility model belongs to the technical field of msw incineration, concretely relates to high-efficient formula msw incineration boiler.

Background

The primary process of garbage incineration is to put a certain amount of garbage materials into a boiler by a grab bucket, push the garbage materials downwards under the staggered movement of a grate, simultaneously, combustion air enters from the lower part of the grate to be mixed with the garbage, so that the garbage is oxidized at high temperature to reduce the volume and become residues which are discharged. Because the burning speed is determined by the contact area between the garbage spreading state and the burning air, the materials can be spread and dispersed as much as possible when burning is carried out. However, the excessive spread area also requires a larger volume of boiler equipment to operate, which virtually increases the space occupation and the equipment manufacturing cost, and therefore, a new technical solution is needed to be perfected.

Detailed Description

The invention is described in further detail below with reference to the drawings.

As shown in fig. 1, a high-efficiency waste incineration boiler 1 comprises a boiler 1, a plurality of primary grates 2, a plurality of secondary grates 3, a plurality of combustion ports 4 and a plurality of slide rails 5. The boiler 1 is a hollow container, the top of one side of the boiler is provided with a feeding hole 1a, the bottom of the other side of the boiler is provided with a slag discharging hole 1b, and a smoke discharging hole 1c is also arranged above the boiler; the primary grates 2 and the secondary grates 3 have the function of conveying materials transversely, a plurality of primary grates 2 are installed at intervals through the side wall of the boiler 1 below the position communicated with the feed port 1a in the inner cavity of the boiler 1 and form a side-by-side array from top to bottom, and a plurality of secondary grates 3 are installed below the primary grates 2 in the same array mode, wherein the secondary grates 3 are closer to the feed port 1a than the primary grates 2; the lower part of each secondary grate 3 is provided with one combustion port 4; in addition, be equipped with a plurality of vertical arrangement on the boiler 1 lateral wall slide rail 5, the both sides of every one-level grate 2 respectively through a slide rail 5 install on boiler 1 lateral wall, one-level grate 2 in the position accessible holding screw 5a is fixed on the slide rail 5.

The utility model discloses a theory of operation is:

as shown in fig. 2, the garbage materials are fed into the boiler 1 through the feeding port 1a, and are respectively fed into the secondary grate 3 and the primary grate 2 from a lower gap and a side space, and at this time, if the materials received by the primary grate 2 are too much or too little, the horizontal height of the materials on the sliding rail 5 can be adjusted in a sliding manner, and the materials are fixed by a set screw 5 a; then, as the first-stage grate 2 and the second-stage grate 3 convey respective materials to the right, combustion gas with different temperatures is introduced into the boiler 1 through a plurality of combustion ports 4 at the bottom, the second-stage grate 3 below is heated, dried and combusted, and is upwards conducted by self heat, under the action of combustion air which is preheated by the combustion of lower-layer materials and upwards diffused in gaps of the grates, the materials on the first-stage grate 2 above are heated and combusted, and then combustion ash slag discharged from the upper furnace and the lower furnace is discharged at a slag discharge port 1b, and combustion smoke is led out from an upper smoke discharge port 1c and is sent into a secondary combustion or post-treatment device. The combustion mode of the double-layer heating forms high-efficiency incineration operation of the fixed space in the boiler 1.
