Description

无害化脱水器 Harmless dehydrator

技术领域 FIELD

[0001] 本实用新型涉及一种物料的灭菌、脱水处理装置,尤其涉及一种可适用于城市生活垃圾处理的脱水装置。 [0001] The present invention relates to a sterilization material, a dehydration treatment apparatus, particularly to a municipal solid waste disposal is applicable to the dewatering device.

背景技术 Background technique

[0002] 目前国内对城市生活垃圾的处理,主要有填埋法、焚烧法、分类处理法等几种方法。 [0002] At present several methods for domestic processing of municipal solid waste, there are landfill, incineration, sorting processing method. 这些方法存在着投资大、占用土地面积大和二次污染等严重不足,使得我国大多数城市生活垃圾只能采用堆放为主的处理方法,这种简单堆放处理的方法由于其占用土地、易滋生细菌和产生腐败气体等缺陷,正越来越严重地影响我们的生活环境和生活质量。 These methods there is a large investment, occupy large areas of land and secondary pollution, a serious shortage, so that the majority of our municipal solid waste treatment methods can only be used piling dominated, piling up this simple treatment method because of its occupation of land, the growth of bacteria and defects corruption gas, is increasingly serious impact on the living environment and our quality of life.

[0003] CN1426856A号中国专利文献公开了一种生活垃圾的处理方法,该垃圾处理方法中包括有磁选、湿式消解等工艺步骤;其使用了消解罐对垃圾进行消解,但消解罐内需充入约0. 9MPa的饱和蒸汽,在加热过程中,不易使垃圾体均勻加热,且罐体内是正压,一旦密封不严,会出现蒸汽外漏的情况,罐体通过封罐加热垃圾,间断开罐的运行方式,出料有间断性; 脱水的过程是通过闪蒸的方法,脱水率偏低,且加热时间长。 [0003] Chinese Patent No. CN1426856A discloses a method for processing garbage, the garbage disposal methods include magnetic separation, like a wet process digestion step; using the digestion tank of the garbage digestion, but digestion tank for an charged saturated steam of about 0. 9MPa, during heating, so that the garbage is not easy to uniformly heated, and the tank is a positive pressure, once Mifengbuyan, there will be leakage of steam, seaming the can body by heating the waste, intermittent opening tank operating mode, there is intermittent discharge; dehydration process by the method of flash evaporation, the dehydration rate is low, and the heating time is long.

[0004] CN1461678A号中国专利文献则公开了一种城市生活垃圾无害化的处理工艺,该处理工艺中采用灭菌脱水罐和干燥罐结合进行垃圾预处理,达到对垃圾灭菌、脱水的作用,后续可结合堆肥、填埋等进行综合处理。 [0004] Chinese Patent No. CN1461678A discloses a document is municipal garbage treatment process, the treatment process employed and the drying vessel sterilization Drainage Jar binding garbage pretreatment, to effect sterilization of garbage, dewatered subsequent composting can be combined, integrated process landfill. 在该处理工艺中,灭菌脱水罐通过表面换热来加热垃圾,换热过程以热传导为主,热辐射较弱,总传热系数偏低,且热源不易控制,加热时间长。 In this treatment process, the sterilization can be dehydrated by heating the surface heat transfer waste, heat conduction to the main heat exchange process, the heat radiation is weak, low total heat transfer coefficient, heat and difficult to control, a long heating time. 要提高传热系数,需提高灭菌脱水罐的壁温,而这对设备的运行不利,甚至可能造成罐体弯曲变形,壁温过高,还会使垃圾发生裂变和分解;且该专利文献中还提到罐体内温度控制在100°C,显然通过提高壁温的方法来提高传热系数不可取,因此,垃圾脱水过程还需配套设置干燥罐。 To improve the heat transfer coefficient, sterilization need to improve dewatering tank wall temperature, which adversely the operation of the equipment, the tank may even cause bending deformation, the wall temperature is too high, so that the garbage will fission and decomposition; and the patent document also mentioned the tank body temperature was controlled at 100 ° C, is clearly desirable to increase the heat transfer coefficient by raising the wall temperature, and therefore, refuse dewatering process needs a matching set of dryer cans.
