Description

一种垃圾焚烧炉的风系统 The refuse incinerator air system

技术领域 FIELD

本发明涉及一种能源环保设备中的焚烧炉,具体地说涉及一种生活垃圾焚烧炉的风系统。 The present invention relates to an environmentally friendly energy incinerator apparatus, particularly to a garbage incinerator air system. 它尤可用于焚烧低热值、高水分、未经分拣的生活垃圾焚烧发电。 It may, in particular for the incineration of low calorific value, high water, unsorted garbage incineration power generation. 背景技术 Background technique

随着现代化生产发展和城市人口增加及其消费水平提高,产生的垃圾污染环境造成社会公害,早已引起各国的重视。 With the increase of urban population and the development of modern production and consumption levels increase, resulting in waste pollution of the environment caused by social nuisance, it has attracted national attention. 目前,城市生活垃圾的处理方法有两大类种即焚烧和卫生填埋,后者因占用大量土地而其渗沥液又多污染地下水,填埋场又造成了二次污染周边环境。 Currently, the treatment of municipal solid waste, there are two kinds namely incineration and sanitary landfill, which is due to take up a lot of land and its addition of leachate contamination of groundwater, the landfill has a secondary pollution caused by the surrounding environment. 国外大多采用垃圾焚烧处理实现了减量化、无害化、资源化目的。 They use a foreign waste incineration achieve the reduction, environmentally sound, resource purposes. 我国垃圾焚烧处理起步不久,垃圾焚烧装置主要有三种:即机械炉排炉、循环流化床炉及热分解炉。 Our fledgling waste incineration, waste incineration plants there are three: the mechanical grate furnace, circulating fluidized bed furnace and thermal decomposition furnace. 热分解炉是国内刚开发的焚烧装置,它有二种形式,一是卧式,最大日处理垃圾量为150t/d,二是立式旋转型,设计最大处理量为100t/d。 Thermal decomposition furnace is newly developed domestic incinerator, which has two forms, one horizontal, the maximum daily waste disposal capacity of 150t / d, the second is vertical rotary type, designed to handle a maximum capacity of 100t / d. 立式旋转热分解炉因其设备系 Vertical rotary system because thermal decomposition furnace equipment

统等一系列问题,尤其含水分大、热值偏低的城市生活垃圾而言,均尚未安 System and a series of problems, especially water containing large, low calorific value of municipal solid waste, it was not yet safe

全、稳定地到达设计额定的处理量。 Whole, the amount of processing design rated stably reach. 中国专利02111455. 2公开了一种生活垃圾焚烧炉。 Chinese patent 02111455.2 discloses a garbage incinerator. 它含有带料斗的炉体、给料机、炉排、位于炉排下的风室、出渣机,其中炉排片含有固结在炉体上的固定片和间隔排列在前后两相邻固定片之间且与往复运动杆件连接的活动片,其特征是:炉排沿垃圾运行方向分成前段和后段两段,接近料斗的前段为向下倾斜的逆推式炉排、后段为顺推式炉排,并且在前、后段炉排的衔接处设置有一定高度的落差。 It comprises a furnace body with a hopper, feeder, grate, grate located in the plenum, Java machine, wherein the grate comprises a consolidation furnace in a fixed plate and spaced around two adjacent fixing pieces connected between the movable blade and the reciprocation of the lever, wherein: the grate is divided into two front and rear sections garbage running direction, close to the pre-stage hopper downwardly inclined backstepping grate, cis-stage push- grate, and the front, at the rear section of the grate adapter is provided having a height gap. 其不足之处,一是,经风室从炉排下进入炉膛提供燃料燃烧时所需的氧量的一次风系统,原设计是四个风室的风门调节杆连在一起,只能同时调节风门开度,不能单独对各风室进行调整,不能根据燃料的变化来调节各风室的风量,使燃料不能很好的在预定区域燃烧。 Its shortcomings, one, the lower plenum grate into the furnace from the combustion of fuel to provide the necessary primary air oxygen system, the original design is four plenum throttle adjustment lever together, while adjusting only throttle opening can not be individually adjusted for each plenum, the air volume can not be adjusted according to changes in each of the plenum of the fuel, the fuel can not burn well in a predetermined area. 甚至当垃圾水分低时,垃圾在第一风室上就能着火燃烧,大大降低了燃烧效率。 Even when the low-moisture garbage, trash can on the first ignition combustion plenum, combustion efficiency is greatly reduced. 二是,高速喷入炉膛有效地扰动烟气和提供燃烧时所需氧量的二次风系统,原设计只有热风,垃圾燃料热值高时,高温二次风喷入炉膛,易超温,影响锅炉超负荷和安全运行,不能很好的保证垃圾的处理量。 Second, efficient high-speed jet into the furnace flue gases and the secondary air system disturbances provide oxygen demand during combustion, only the original design of the hot air, high heat value fuel garbage, high temperature secondary air injected into the furnace, easy to over-temperature, overload and affect the safe operation of the boiler, can not guarantee a good deal of garbage. 发明内容 SUMMARY

本发明要解决的技术问题在于,为了弥补现有垃圾焚烧炉的风系统调节不合理,导致焚烧效率、安全运行、垃圾的处理量方面的不足之处,而提供一种适应高水分、低热值生活垃圾焚烧,安全运行、燃烧效率高、垃圾的处理量大、结构简单的垃圾焚烧炉的风系统。 The present invention to solve the technical problem is that, in order to compensate for existing waste incinerator air system of regulation is unreasonable, resulting in deficiencies combustion efficiency, safe operation, handling of garbage areas, while providing an adaptive high moisture, low calorific value municipal solid waste incineration, safe operation, high combustion efficiency, large capacity, simple structure garbage incinerator waste air system.

本发明为解决上述技术问题而采用如下的技术方案: 一种垃圾焚烧炉的风系统,包括向炉排供风的一次风系统和向炉膛供风的二次风系统;其特征在于:所述的一次风系统是从第四烟道中的烟气空气预热器中引热空气通过一次风管进入炉排下部的一组风室;风室上设置一组风门,风门分别由电机驱 The present invention solves the above technical problems, the following technical solutions: A waste incinerator air system, the air system including a grate and a secondary air supply air supply air to the furnace system; characterized in that: said the primary air is introduced from the fourth flue system the air preheater flue gas by a set of hot air plenum primary air duct into the lower grate; a set of dampers disposed on the plenum, respectively, driven by a motor damper
