Problems solved by technology

But its disadvantage is that when the incinerator is turned on and off, the furnace temperature passes through the temperature range of dioxin production (360-820°C), and it is easy to produce dioxins under the condition of incomplete control.

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with specific embodiments.

[0036] Such as Figures 1 to 3 shown. The invention discloses an incineration device for harmless, reduction and recycling of rural garbage, comprising a furnace 10, a material bin 3 arranged at the entrance of the furnace 10, and used for pushing the garbage in the material bin 3 into the furnace 10 The pusher 4; the flue gas outlet at the top of the furnace 10 is sequentially connected to the air preheater 9, the water-cooled heat exchanger 8, the cyclone separator 13, the tail gas treatment device 12, and the chimney 15 through pipelines;

[0037] The incineration device also includes a motor 1, a primary blower 7, a secondary air assembly 2, and a nozzle array composed of a plurality of nozzles 16; the motor 1 is used to drive the secondary air assembly 2 and the primary blower 7 to work; each nozzle 16 is obliquely distributed along the inner wall of the ou...

Abstract

The invention discloses a rural garbage harmless, reduction and recycling incinerator and method. A smoke outlet in the top of a hearth is sequentially connected with an air preheater, a water coolingheat exchanger, a cyclone separator, a tail gas treatment device and a chimney through a pipeline, the incinerator further comprises a motor, a primary fan, a secondary air assembly and a nozzle array composed of multiple nozzles, the motor is used for driving the secondary air assembly and the primary fan to work, the nozzles are distributed in an inclined manner in the circumferential directionof the inner wall of a flue outlet in the top of the hearth, a spiral air flow is formed in a flue, and smoke is driven to be entrained and spirally ascend, the secondary air assembly sucks gas emitted by garbage from a material bin, meanwhile, negative pressure is formed in the material bin, and the gas is emitted to the flue outlet in the top of the hearth through a nozzle; the incinerator andmethod have the beneficial effects of being high in combustion efficiency, nearly zero in emission, low in running cost, wide in fuel application and the like, and are suitable for rural garbage harmless, reduction and recycling incinerating treatment of the China.

Description

technical field [0001] The invention relates to incineration treatment of rural garbage, in particular to an incineration device and method for harmless, volume reduction and resource recovery of rural garbage. Background technique [0002] Rural waste can be divided into two categories: domestic waste and productive waste. Among them, domestic waste refers to the solid waste produced by villagers in their daily life or when providing services for daily life. The productive waste includes farming waste (such as straw, plastic film, pesticide and chemical fertilizer packaging, etc.), aquaculture waste (such as domestic poultry manure, etc.), industrial waste, medical waste and construction waste. After continuous development in our country, the output of rural garbage is also constantly increasing. At the same time, there are great differences in the source and composition of rural waste in different regions. [0003] At present, the main treatment methods for rural garbag...
