管壳式冷凝器 meaning in English

shell and tube condenser
shell and tube cooler

It has been shown that this updated sampling and measurement method , which can measure the content of tar and dust individually , appears much more precise and credible , particularly aiming at the characteristic of heavy tar and dust content in biomass gas . this clarification system that adopts two - level shell and tube condensers and one tar removal filter , has the advantages of high removal efficiency ( 97 % ~ 98 % ) and low operating cost . besides , it has been made more environmentally friendly considering that wastewater from condensers has measured up to related effluent state standards after being disposed in tar clarifier - tank
多次试验表明：针对生物质气浙江大学硕士学位论文含焦油灰尘量大的特点，改进的生物质焦油取样测量法可实现焦油和灰尘的分离，有较高准确性和可靠性；采用二级管壳式冷凝器与一级干式过滤器结合的燃气冷凝净化系统不但净化效率高（ 97 98 ）、运行费用低，而且含焦油废水二经过澄清池澄清处理后可达到国家相关污水排放标准，避兔了湿式净化系统的水污染；兼顾净化效果、经济性和减少污染考虑，采用以半焦为吸附材料的于式净化系统可以达到炊用燃气对焦油含量的要求。
