The present invention discloses a system and method for preparing piperylene and dicyclopentadiene. The system comprises: a second dimerization reactor, a carbon five and a pentadiene tower, a carbon six and dicyclopentadiene tower, a carbon five and a piperylene tower as a separation wall rectification tower, a PD product Exports; carbon six and dicyclopentadiene tower separation wall column, the top of DCPD products. The method comprises the following steps: (1) feeding a C5 fraction into a second dimerization reactor, feeding the top material into a first zone of a carbon five and a piperylene column, producing a piperylene product from the second subregion of the piperylene product
