The purpose of the invention can be realized by the following technical scheme: the utility model provides a jar is retrieved in condensation, includes the condenser, the upper end of condenser be provided with the filter that has the exhaust joint, the lower extreme of condenser be provided with low temperature and amass the fluid reservoir, low temperature amass fluid reservoir and condenser between set up vapour and liquid separator, be provided with the air inlet joint on this vapour and liquid separator, its characterized in that, vapour and liquid separator in be provided with the flow resistance device that can slow down the air current and flow, this air current flows into by air inlet joint, makes the kinetic energy decline of air current and form gas-liquid separation through the flow resistance device, liquid inflow low temperature amass fluid reservoir, gaseous flow direction condenser, gaseous process condenser cooling turn into liquid inflow low temperature amass fluid reservoir again, residual gas passes through the filter, by the exhaust joint discharge.

The condensing recovery tank mainly comprises a condenser, a filter, a gas-liquid separator and a low-temperature liquid accumulation tank, all parts are manufactured separately and then assembled into a whole, and the condensing recovery tank is convenient to produce and manufacture. The gas flow continuously and repeatedly impacts a flow resistance element in the flow resistance device through the flow resistance device to reduce the flowing kinetic energy of the gas flow, further continuously reduce the entrainment capacity of the gas flow, and then form a gas-liquid separation effect through modes of centrifugal separation, surface adsorption, natural deposition, differential penetration and the like; the gas is cooled by the condenser and is converted into liquid again, the liquid is captured by the condenser and the filter and then flows downwards into the low-temperature liquid accumulation tank again, and the liquid recovery effect is good; set up the flow resistance device in this vapour and liquid separator, the air current passes through the flow resistance device and can effectually slow down the velocity of flow, causes the air current to carry out abundant separation, and the gas phase of air current, liquid phase separation effect are better, and structural stability is high, convenient to use.
