Description
技术领域 technical field
本实用新型涉及工业危废物的净化处理技术领域。 The utility model relates to the technical field of purification treatment of industrial hazardous waste.
背景技术 Background technique
目前国内外工业危险废物焚烧炉应用较多的处理工艺有固定与机械炉排、液体喷射炉和热解气化炉等。机械炉排由于活动件多，设备维修较为复杂，投资也较高，多用于处理生活垃圾；液体喷射炉主要用于废液的焚烧，进料具有局限性；对于10t/d 以下的焚烧炉，热解气化炉应用较多，然而，热解气化炉要求入炉物料密度小于300kg/m3，需进行配料预处理。 At present, domestic and foreign industrial hazardous waste incinerators are widely used in the treatment of fixed and mechanical grates, liquid injection furnaces and pyrolysis gasification furnaces. Due to the large number of moving parts, the maintenance of the mechanical grate is relatively complicated and the investment is relatively high, so it is mostly used to treat domestic waste; the liquid injection furnace is mainly used for the incineration of waste liquid, and the feed has limitations; for the incinerator below 10t/d, Pyrolysis and gasification furnaces are widely used. However, pyrolysis and gasification furnaces require the density of the incoming material to be less than 300kg/m 3 , and batching pretreatment is required.
对于危废焚烧烟气处理的脱NOx工艺，工程上采用较多的有选择性非催化还原工艺（SNCR）和选择性催化还原工艺（SCR）两种。但是SCR烟气在进入催化脱氮器之前需要加热，且所需催化剂市场主要为海外品牌占领，系统投资大。 For the deNOx process of hazardous waste incineration flue gas treatment, there are two kinds of selective non-catalytic reduction process (SNCR) and selective catalytic reduction process (SCR) used in engineering. However, SCR flue gas needs to be heated before entering the catalytic denitrification device, and the required catalyst market is mainly occupied by overseas brands, and the system investment is large.
在危险废物焚烧烟气净化工艺中，从世界范围而言，湿法工艺应用最多。但是湿法水耗较大，产生废水量大，系统复杂，初次投资费用偏高且运行费用高。 In the flue gas purification process of hazardous waste incineration, the wet process is the most widely used in the world. However, the wet method consumes a lot of water, produces a large amount of wastewater, the system is complicated, the initial investment cost is high and the operating cost is high.

In order to ensure the stability of the incineration working conditions in the rotary kiln 2 and prevent tempering, a kiln head sealing door 2-1 and a kiln tail sealing door 2-2 are respectively provided at the kiln head and the kiln tail of the rotary kiln 2. The secret door opened at the wrong time. The liquid waste is sent to the rotary kiln 2 and the secondary combustion chamber 3 respectively by the corrosion-resistant pump 27 for incineration. Generally, the waste liquid with high calorific value is incinerated in the rotary kiln 2, and part or all of the auxiliary fuel is replaced to save operating costs; in the second combustion chamber 3, other waste liquids with low calorific value that are not suitable for incineration in the rotary kiln can be incinerated.
危险废物通过进料机构送入回转窑2本体内进行高温焚烧，经过60min（45～75min）左右的高温焚烧，物料被彻底焚烧成高温烟气和灰渣，其操作温度应控制在850℃左右，高温烟气自回转窑2的窑尾进入二燃室3，焚烧灰渣从二燃室3的排渣口进入水封刮板出渣机15，水冷后进入灰仓，定期送至固化车间处理。 Hazardous waste is sent into the rotary kiln 2 body through the feeding mechanism for high-temperature incineration. After about 60 minutes (45-75 minutes) of high-temperature incineration, the material is completely incinerated into high-temperature flue gas and ash. The operating temperature should be controlled at about 850°C , the high-temperature flue gas enters the second combustion chamber 3 from the kiln tail of the rotary kiln 2, and the incineration ash enters the water-sealed scraper slag discharger 15 from the slag outlet of the second combustion chamber 3, enters the ash bin after water cooling, and is regularly sent to the curing workshop deal with.
回转窑2采用顺流式，包括窑头、本体、窑尾、传动机构等几部分。窑头的主要作用是完成物料的顺畅进料、布置一个多燃料燃烧器及助燃空气的输送、以及回转窑与窑头的密封。为保证物料向窑尾顺利传输，回转窑2以2°的倾斜度安装，窑头高于窑尾。 Rotary kiln 2 adopts downstream type, including kiln head, body, kiln tail, transmission mechanism and other parts. The main function of the kiln head is to complete the smooth feeding of materials, arrange a multi-fuel burner and the delivery of combustion air, and seal the rotary kiln and the kiln head. In order to ensure the smooth transmission of materials to the kiln tail, the rotary kiln 2 is installed with an inclination of 2°, and the kiln head is higher than the kiln tail.
为了避免辐射和二燃室3外壳过热，二燃室3设计成由钢板和耐火材料组成的圆柱筒体。在二燃室3引入两只第二燃烧器13，两只第二燃烧器13的出风口为同一顺向。焚烧时火焰相切向上形成涡流，增加扰动达到充分分解有害成分的目的。回转窑2内少量没有完全燃烧的气体在二燃室3内得到充分燃烧，并提高二燃室3温度，在二燃室3内温度始终维持在1100℃以上，烟气在二燃室内停留时间将大于2s，烟气中的二噁英和其它有害成分的99.99%以上将被分解掉。 In order to avoid radiation and overheating of the shell of the second combustion chamber 3, the second combustion chamber 3 is designed as a cylinder made of steel plates and refractory materials. Two second burners 13 are introduced into the second combustion chamber 3, and the air outlets of the two second burners 13 are in the same forward direction.

The reaction raw materials are sprayed from the discharge end of the denitrification (nitration) device 19 to the smoke inlet channel of the waste heat boiler 4, and the denitrification process adopts non-catalytic reduction (SNCR method) to control NOx. Then, after heat recovery by the waste heat boiler 4 , the flue gas from the outlet of the waste heat boiler 4 enters the quench tower 5 , where it is rapidly cooled and lowered in temperature. The flue gas at the outlet of the quench tower 5 is fully mixed with the 20 % Ca(OH) slurry injected from the atomizing nozzle in the semi-dry reaction tower 6, and acid gases such as SOx and HCl in the flue gas are mixed with Ca(OH) ) 2 is removed after the neutralization reaction; the flue gas enters the dry deacidification tower 7 again.
