The invention discloses a device and a method for preparing methanol by using low-temperature plasma in cooperation with a catalyst. Low-temperature plasma is used for generating discharge, H2 and CO2 are activated in the plasma reactor, the thermocatalytic reaction rate is increased, and energy consumption is reduced; condensate water is introduced to the outer side of the low-temperature plasma to improve the conversion rate and selectivity of the reaction. Gas treated by the low-temperature plasma is fed into the thermocatalytic reactor, a partition plate is arranged in the thermocatalytic reactor, so that backflow is formed at a local position in the thermocatalytic reactor, a plurality of catalyst outer bed layers are arranged inside and outside the partition plate, and different positions can be filled with different types of solid catalysts; according to the invention, the reaction of preparing methanol from CO2 can be carried out under normal pressure, the energy consumption is ...
