Pull up and down push driven reverse push garbage incinerator

Abstract

The invention discloses a pull-up push-down driven reverse push garbage incinerator, which comprises a feed hopper, a feeding mechanism, grates, a heath, a grate lee chamber, a slag falling well and a slag discharger, wherein the grates are divided into static grates and dynamic grates, the static grates and the dynamic grates are arranged alternately up and down to form a column, a dynamic gratedrive consists of an upper section and a lower section, the driving mechanism of the upper section is arranged at the upper end of the grates, and the driving mechanism of the lower section is arranged at the lower end of the grates; and an air chamber is formed below the grates, and an electric air door is arranged on an air inlet pipeline of the air chamber. The garbage incinerator has the advantages that: the movement speed of the grates of each section is adjustable, and the grates can be properly lengthened, so that the burning treatment time is prolonged; the incinerator of different capacity can be combined; and the grates of each column are independently driven and do not interfere with one another, so the incinerator has simple structure and can be modularized. The intertwined garbage cluster is easily scattered, and the garbage is mixed uniformly and burnt stably; the incinerator is provided with a heat expansion absorption device, so that the grate sheets are not blocked due to expansion; and the air quantity of the air chamber can be adjusted, so that the garbage can be stably burnt.

Description

technical field [0001] The invention belongs to the field of municipal solid waste incineration equipment. In particular, it relates to the technology of reverse push grate garbage incinerator. It is especially suitable for the treatment of municipal solid waste with low calorific value, high ash content, high moisture content, unsorted and fluctuating calorific value. Background technique [0002] Domestic garbage incinerators in the prior art are generally divided into forward-pushing garbage incinerators and reverse-pushing garbage incinerators. There are two kinds of reverse push garbage incinerators: one is the upper pull single drive, the disadvantage of this kind of garbage incinerator is: the material layers are all driven at the same speed, it is not easy to pull apart the clumps in the garbage, during the incineration process, the gap between the garbage The distance between them has not changed significantly, and the distance between the garbage basically remain...

Problems solved by technology

There are two kinds of reverse push garbage incinerators: one is the upper pull single drive, the disadvantage of this kind of garbage incinerator is: the material layers are all driven at the same speed, it is not easy to pull apart the clumps in the garbage. The distance between them has not changed significantly, and the distance between the garbage basically remains the same as when it enters the furnace until it is discharged from the incineration grate. The garbage is not fully unfolded and scattered, and the garbage cannot be completely incinerated; the adjustment of the disposal speed of the burnt garbage is limited; The thickness of the material layer is not easy to be uniform; limited by the strength and structure, the length of the general grate grate is short, and the effect of waste incineration is not ideal for low calorific value, high ash content, high moisture, unsorted and large calorific value fluctuations

The other is a multi-drive reverse-push garbage incinerator. The movement speed of each section of this garbage incinerator can be adjusted separately, and the material layer of the garbage can be distributed more evenly. The disadvantages are: the drying section, the burning section, the burning section Each section is driven by the oil cylinders of each section. Due to too many driving oil cylinders, the structure of the waste incinerator is complicated, cumbersome and not compact; the coordination between the driving oil cylinders is not good, sometimes resulting in uneven waste in the drying section and the burning section. Or discontinuous; multi-drive reverse thrust waste incinerators are generally driven on both sides, and the grate can only adopt a two-column structure, which is difficult to expand capacity
