Description

一种炉排型垃圾焚烧炉混烧污泥的处理系统A grate type waste incinerator co-combustion sludge treatment system

技术领域 technical field

本实用新型涉及一种炉排型垃圾焚烧炉混烧污泥的处理系统。 The utility model relates to a treatment system for co-burning sludge of a grate type garbage incinerator.

背景技术 Background technique

生活垃圾焚烧发电技术具有环保和能源的双重效益,近年来,我国建设现代化大型生活垃圾焚烧厂的发展速度很快,全国共建有200多座生活垃圾焚烧炉,其中大部分是炉排型焚烧炉。我国城镇生活垃圾的突出特点表现为:含水率高、热值低、厨余类含量高、可回收成分低。对于焚烧厂而言,高厨余与高水分会影响垃圾焚烧工况,通常需要添加热值比较高的秸秆作为辅助燃料,方可维持系统正常运行。但秸秆密度轻、挥发分含量较高、燃烧速度快,秸秆直接掺入焚烧炉助燃很难与垃圾在炉内同步焚烧。 Domestic waste incineration power generation technology has dual benefits of environmental protection and energy. In recent years, the construction of modern large-scale domestic waste incineration plants in my country has developed rapidly. There are more than 200 domestic waste incinerators in the country, most of which are grate type incinerators. furnace. The outstanding characteristics of my country's urban domestic waste are: high moisture content, low calorific value, high content of kitchen waste, and low recyclable content. For incineration plants, high food waste and high moisture will affect the working conditions of waste incineration. It is usually necessary to add straw with a relatively high calorific value as auxiliary fuel to maintain the normal operation of the system. However, the straw has light density, high volatile content, and fast burning speed. It is difficult for the straw to be directly mixed into the incinerator to support combustion and to be incinerated synchronously with the garbage in the furnace.

另外,2010年,全国中等以上城市生活垃圾清运量为1.56亿吨,废水排放总量589.2亿吨,其中生活污水354.8亿吨,剩余污泥(含水率80%)产生量达1683.52万吨。污泥所具有的高热值是污泥作为资源被利用的最有价值部分,如果将污水处理厂污泥的热值完全利用,可以使污泥在得到彻底处理的同时,产生经济效益。然而污泥的热值资源能被利用有两个基本条件:一是污泥的含水率必须尽可能降低;二是污泥中的有机质必须保存下来。污泥干化的主要成本在于热能,热能的支出占干化运行成本的80%以上,选择和利用恰当的热源是降低成本的关键。为降低污泥干燥能耗,有必要寻求低成本的干化热源。浙江大学翁焕新提出了利用电厂烟气直接干燥污泥的工艺,该工艺能将烟气废热有效利用,但烟气与污泥直接接触容易使烟气和污泥交叉污染,干化后产生的含有大量臭气的烟气需要再治理。 In addition, in 2010, 156 million tons of domestic garbage were removed and transported in cities above the middle level, the total amount of wastewater discharge was 58.92 billion tons, of which domestic sewage was 35.48 billion tons, and the generation of residual sludge (with a moisture content of 80%) reached 16.8352 million tons. The high calorific value of sludge is the most valuable part of sludge being used as a resource. If the calorific value of sludge in sewage treatment plants is fully utilized, the sludge can be thoroughly treated and at the same time generate economic benefits. However, there are two basic conditions for the calorific value resources of sludge to be utilized: one is that the moisture content of sludge must be reduced as much as possible; the other is that the organic matter in sludge must be preserved. The main cost of sludge drying lies in heat energy, which accounts for more than 80% of the drying operation cost. Selecting and utilizing an appropriate heat source is the key to reducing costs. In order to reduce the energy consumption of sludge drying, it is necessary to find a low-cost drying heat source. Weng Huanxin of Zhejiang University proposed a process of using power plant flue gas to directly dry sludge. This process can effectively utilize the waste heat of flue gas, but the direct contact between flue gas and sludge is likely to cause cross-contamination of flue gas and sludge. A large amount of foul-smelling flue gas needs to be treated again.
