无害化脱水器 Harmless dehydrator

技术领域 Technical Field

[0001] 本发明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 material sterilization, dehydration processing device, and more particularly to an applicable to municipal solid waste dehydrator.

背景技术 Background

[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, the urban garbage treatment, there are several ways to landfill, incineration, classification 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 exist large investment, land area occupied Japan a serious shortage of secondary pollution, so that the majority of our municipal solid waste only use stack-based approach, this simple method of stacking process because of its occupation of land, the growth of bacteria gas and other defects and corruption, is increasingly serious impact on our living environment and 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 [0003] CN1426856A number of Chinese patent discloses a method for processing garbage, the garbage disposal methods include magnetic separation, wet digestion and other process steps; the use of a digestion tank for garbage digestion, but digestion tank needs filling approximately

0.9MPa的饱和蒸汽,在加热过程中,不易使垃圾体均匀加热,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。 0.9MPa saturated steam in the heating process, not easy to make garbage uniformly heated, and is a positive pressure inside the tank, once Mifengbuyan the case of steam leakage occurs, the tank is heated by sealing garbage cans of intermittent operation mode, there are intermittent discharge; dehydration process by flashing method, 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] CN1461678A number of Chinese patent literature is disclosed a municipal garbage treatment process, the treatment process using sterilized jar and dried dehydrated garbage cans combined pretreatment reach garbage sterilization, dehydration effect follow-up can be combined with compost, landfill and other comprehensive treatment. 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, sterilization dewatering tank by surface heat exchanger to heat the waste, the main heat transfer process to heat conduction, heat radiation is weak, low overall heat transfer coefficient and the heat is not easy to control, 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, the need to improve the dewatering tank wall temperature sterilization, which is detrimental to the equipment running, and may even cause bending deformation of the tank wall temperature is too high, but also the garbage fission and decomposition; and the patent literature also mentioned the tank body temperature is controlled at 100 ° C, apparently by increasing the wall temperature of ways to improve the heat transfer coefficient is not desirable, therefore, the need to complete the dewatering process the garbage cans set up drying.
