无害化脱水器 Harmless dehydrator

技术领域 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 municipal solid waste dewatering device.

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 treatment of municipal solid waste, 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 to invest large land area occupied by Japanese secondary pollution, a serious shortage, making the majority of our municipal solid waste only use stacked 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 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] CN1426856A number of Chinese patent discloses a method of treating solid waste, which includes waste disposal method in magnetic separation, wet digestion and other process steps; the use of the digestion tank garbage digestion, but digestion tank needs filling about 0. 9MPa saturated steam in the heating process, not easy to make garbage uniformly heated and pressurized tank body is once Mifengbuyan situation steam leakage will occur, the tank is heated by sealing garbage, intermittent open tank operation mode, there are intermittent discharge; dehydration process by flashing method, the low rate of dehydration and heat for a long time.

[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 documents are disclosed a municipal garbage treatment process, the treatment process using sterilized jar and dry dehydrated garbage cans combined pretreatment reach for junk 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 the treatment process, sterilization dehydration tank is heated by the heat exchanger surface rubbish, heat conduction heat transfer process-based, thermal 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 result in bending the tank wall temperature is too high, but also to refuse fission and decomposition; and the patent literature also mentioned the tank body temperature is controlled at 100 ° C, apparently by increasing wall temperature of ways to improve the heat transfer coefficient is not desirable, therefore, the need to complete the dewatering process garbage cans set up dry.
