作者:杭州沈氏节能科技股份有限公司 浏览:106 发表时间:2020-06-22 15:13:17

杭州沈氏微化工事业部,专注于使用微反应技术从事连续工艺开发。目前有研发团队20人,多人曾供职于知名外企和制药企业。总部实验室约400平米,同时在上海有机所及中国计量大学建有实验室。

我们实行“一站式”项目开发服务:提供微反应器工艺研发、工业化系统集成、工业化“交钥匙”工厂全流程技术服务

 

集成式微通道反应器:由换热单元、反应单元组成,通过扩散焊接一体成型,无任何除母材之外的其他成分。

高换热效率:换热流道采用微通道结构设计,有效强化传热表面,提升换热效率;整体采用扩散焊接方式加工,无母材之外的任何接触热阻;

高传质高收率:反应流道应用切割阻挡原理,采用微通道结构设计,大幅提升传质效率;

高承压:扩散焊接使不同单元间融为一体,承压可达20MPa以上;微通道结构方式使流道内部在高压情况下受力大幅降低,提高使用压力;

使用安全:高通量、低滞留量、强换热,大幅因降低反应过程产生的安全问题;

连续可控:集成式方案设计、温度流量控制调节精度高、可实现大通量连续化生产。

Shenshi's microreactor and its application

Hangzhou Shenshi Micro-Chemical Division focuses on continuous process development using micro-reaction technology. There are currently 20 R & D teams, many of whom have worked in well-known foreign companies and pharmaceutical companies. The headquarters laboratory is about 400 square meters, and has laboratories in Shanghai Organic Institute and China Jiliang University.

We implement a "one-stop" project development service: provide micro-reactor process development, industrialized system integration, and industrialized "turnkey" factory full-process technical services.

Integrated microchannel reactor: It is composed of heat exchange unit and reaction unit, and is integrally formed by diffusion welding without any other components except the base material.

High heat exchange efficiency: The heat transfer runner adopts micro-channel structure design, which effectively strengthens the heat transfer surface and improves the heat exchange efficiency; the whole is processed by diffusion welding without any contact thermal resistance except the base material;

High mass transfer and high yield: The reaction flow channel uses the cutting blocking principle and adopts a micro-channel structure design to greatly improve the mass transfer efficiency;

High pressure-bearing: Diffusion welding integrates different units, and the pressure-bearing can reach more than 20MPa; the micro-channel structure makes the internal force of the flow channel greatly reduced under high-pressure conditions, increasing the use pressure

Safety in use: high flux, low retention, and strong heat exchange, greatly reduce the safety problems caused by the reaction process;

Continuously controllable: integrated scheme design, high accuracy of temperature and flow control, and large-volume continuous production.
