A heat pump system may include a cooling assembly disposed on a vehicle to circulate electric devices with coolant through a cooling line, wherein the cooling assembly includes a radiator disposed at a front side of the vehicle, uses a water pump to circulate coolant through the cooling line, and cools the supplied coolant through heat exchange with outside air, and a cooling fan that blows wind through the radiator, an air conditioning assembly connected to a refrigerant line connected to the cooling assembly to control heating and cooling, and a heat exchanger connected to the cooling line such that the coolant is circulated therein, selectively uses the waste heat generated from the electric devices according to modes to vary the temperature of the coolant, and is connected to the refrigerant line of the air conditioning assembly such that an inflow refrigerant exchanges heat with the coolant.

The invention relates to a separation method and separation device for a reform reaction product, and particularly relates to a hydrogen pre separation method of the reform reaction product. The separation method mainly includes the following steps: the reform reaction product (1) and reform reaction feed materials (2, 3), after heat transfer by (4), directly enters into an additionally arranged pre separation tank (7); a pre separation gas phase (9), after cooling by an air cooler(11), enters a subsequent separation tank (12) and a recontact part for separating circulating hydrogen (13) and high purity hydrogen; a pre separation liquid phase (10), after mixing with a recontact tank liquid phase (8), directly enters into a subsequent fractionation part. The separation method reduces the flow quantity of repeated cooling and heating material flows, reduces the heating load of the fractionation part, and alleviates the contradiction of summer cooling underload, and compared with the prior art, the separation method reduces the cooling load by 14.5%, reduces the heating load by 18.2%, and is remarkable in energy-saving effect.

The invention relates to a lithium battery pole piece coater drying system adopting heat pump heat recovery and barrel pump circulating. The lithium battery pole piece coater drying system comprises adrying channel, a long air channel, an air discharging assembly, a lower heating assembly, an upper heating assembly, a heat pump system, a host and an air heat exchanger, wherein the lower heating assembly and the upper heating assembly are used for heating the drying channel. The host is used for achieving heat exchange between an air channel of the lower heating assembly and an air channel ofthe upper heating assembly, and the heat pump system is used for conducting heat exchange with fresh air; the air heat exchanger comprises two air flow passages conducting heat exchange mutually; an inlet of the first air flow passage communicates with an air channel of the heat pump system, and an outlet of the first air flow passage communicates with the air channel of the lower heating assembly; and an inlet of the second air flow passage communicates with the air discharging assembly and receives the air discharged by the air discharging assembly, and an outlet of the second air flow passage serves as a discharging opening. Compared with the prior art, the high-temperature requirement of lithium battery pole piece drying is met through heat pump heat recovery and barrel pump circulating, the heating load of the lithium battery pole piece drying system is lowered as far as possible, and meanwhile potential safety hazards are reduced.

The invention relates to a refining method and device for n-propyl acetate esterification synthesis. The refining method comprises the following steps: feeding a crude product obtained in an n-propyl acetate reaction section into an esterification tower, performing preliminary separation on the n-propyl acetate in the esterification tower through a rectifying mode, and evaporating out raw ester consisting of the n-propyl acetate, water and part of n-propyl alcohol from the tower top of the esterification tower; after condensing the raw ester through a tower-top condenser, feeding the condensed raw ester into a tower-top layering machine for layering, refluxing a lower-layer water-phase part to an esterification tower, completely extracting and feeding an upper-layer organic phase into a pervaporation membrane separator to perform separation, so as to obtain dehydrated raw ester; enabling water and a little n-propyl acetate in a solution at a feed liquid side to penetrate through the pervaporation membrane in the form of steam, so as to obtain a penetrating fluid, and returning the penetrating fluid to tower-top layering machine of the esterification tower and discharging the layered penetrating fluid from the water phase; re-feeding the dehydrated raw ester into a refining tower to obtain a n-propyl acetate finished product. According to the refining method, the recovery rate is high, the process is simple, the safety coefficient is high, the feed liquid circulation volume is small, the operation energy consumption is low, and a third component is not added.
