由多台过滤器并联组成的一维滤器系统,已广泛用于环境保护工程的废气净化及地下工程的防护通风系统中。过滤器流量分布是否均匀直接关系到过滤器的利用效率和使用寿命,因而研究滤器系统的流量均布设计有重要的实际意义。前人时均匀送风管的设计计算方法做过不少工作。但他们所研究的对象或为分布管向大气排气.或为均匀阻 A one-dimensional filter system consisting of multiple filters in parallel has been widely used in the exhaust gas purification of environmental protection projects and the protective ventilation system of underground engineering. Whether the flow distribution of the filter is even or not is directly related to the utilization efficiency and the service life of the filter. Therefore, it is of great practical significance to study the uniform flow design of the filter system. The former has done a lot of work in designing calculation methods for uniform ducts. However, the objects they studied were either exhausted to the atmosphere for the distribution pipe or evenly blocked.
