废轮胎热解工艺数据
收藏资源简介:
本项目适用于废轮胎的无害化、资源化的再生利用用途、通过对废轮胎胶粒的充分热解(精准控制热解关键参数),产生固体炭黑、热解油和不凝气三相产物,在有效处理废轮胎废弃物的同时生成具有较高经济价值的热解产物,有效实现废轮胎的精准高值转化与低碳高效利用。根据DCS系统中的胶粒处理量Qt,预热段出口温度T1,热解段本体温度T2,提质段本体温度T3,根据热解能耗量预测不凝气的消耗量及总烟气量,根据烟气放热量控制冷却段和冷凝器循环冷却水量,保证产物被充分冷却;算法可简单表示为:Qt=α1q1(T5-T4)+α2q2(T7-T6)+βq3(T9-T8);其中q为烟气流量,q1、q2、q3分别为热解段中心、热解段夹套及提质段夹套烟气流量,以α1q1(T5-T4)为例,T4、T5为烟气出口入口温度,α1为对应的系数。
This project is designed for the harmless and resource-oriented recycling and reuse of waste tires. Through sufficient pyrolysis of waste tire rubber particles with precise control over key pyrolysis parameters, three-phase products including solid carbon black, pyrolysis oil and non-condensable gas are generated. While effectively treating waste tire waste, this process produces pyrolysis products with high economic value, thereby achieving precise high-value conversion and low-carbon efficient utilization of waste tires. Based on the rubber particle processing capacity Qt, preheating section outlet temperature T1, pyrolysis section main body temperature T2 and upgrading section main body temperature T3 in the DCS system, the non-condensable gas consumption and total flue gas volume are predicted according to the pyrolysis energy consumption. The circulating cooling water volume for the cooling section and condenser is controlled based on the flue gas heat release, ensuring that the products are fully cooled. The algorithm can be simply expressed as: Qt=α1q1(T5-T4)+α2q2(T7-T6)+βq3(T9-T8); where q denotes flue gas flow rate, q1, q2 and q3 are the flue gas flow rates at the pyrolysis section center, pyrolysis section jacket and upgrading section jacket respectively. Taking α1q1(T5-T4) as an example, T4 and T5 are the inlet and outlet temperatures of the flue gas, and α1 is the corresponding coefficient.
