The invention discloses a baffling dust removal heat pump type drying room. An inner circulating bifurcated fan is arranged in the drying room, and comprises a long shaft and blades. The blades are in a long strip shape, and the sections of the blades are in the shape of a hollow wedge symmetric about the radial direction and center of an impeller shaft. The two ends of each blade are inserted into end discs, and the long shaft is connected and fixed with the end discs through spokes. A draught hood and an air inlet hood are arranged at the two ends of the drying room respectively, the draught hood is connected with an induced draft fan, and the induced draft fan is connected with an evaporator of a heat pump system through a dust remover and then is evacuated. The evaporator of the heat pump system is connected with a main engine through a refrigerant pipe, and the main engine is connected with a condenser through a refrigerant pipe. The air outlet end of an air blower is connected with the air inlet hood through the condenser. The induced draft fan and the impeller of the bifurcated fan are both designed to be of a hollow symmetric structure, and are free of dust accumulation, light, firm and durable. Heat pump cross flow drying and tail heat recovery are especially suitable for being adopted in a low drying temperature system, the nutritional ingredients of thermosensitive substances can be prevented from being damaged, and efficient drying, dust removal and heat recovery are completed with low energy consumption through the system.

The present invention relates to a geothermic electric heating static heat-stored heating heat quantity slowly-releasing structure, its construction process and application. Its structure comprises up-down laminated heat-storing layer and heat quantity slowly-releasing layer, the geothermic cable is embedded in the heat-storing layer formed from heat-storing material whose heat-conducting coefficient is 0.3-0.79w.m(-1).k(-1), said heat-storing layer is covered with the slowly-releasing layer formed from slowly-releasing material whose heat-conducting coefficient is 0.04-0.07 w.m(-1).k(-1), and the temp. sensor is embedded in the slowly-releasing layer, and is series-connected with geothermal cable loop. Its application includes the following steps: starting power supply to supply power to geothermic cable, and storing heat energy in heat-storing layer, then slowly-releasing the heat energy to heating space by means of slowly-releasing layer.

The invention relates to a heat pump circulating system and a method thereof. The heat pump circulating system comprises a compressor, an internal heat exchanger, a throttling valve, an external heat exchanger and a four-way valve. The four-way valve is respectively connected with the refrigeration working medium entrance of the compressor, the refrigeration working medium exit of the compressor,the internal heat exchanger and the external heat exchanger; the four-way valve is provided with a first valve position and a second valve position; when the four-way valve is positioned at the firstvalve position, the refrigeration working medium exit of the compressor is connected with the external heat exchanger and the refrigeration working medium entrance thereof is connected with the internal heat exchanger; and when the four-way valve of the compressor is positioned at the second valve position, the refrigeration working medium exit of the compressor is connected with the internal heat exchanger and the refrigeration working medium entrance thereof is connected with the external heat exchanger which is internally filled with a heat storage agent. The heat pump circulating system and the method thereof adopt water, especially tap water, as a heat source with low cost and high heat exchange efficiency so as to be capable of improving the circulating heat efficiency of the heat pump.

The invention discloses a cyclone dust removal heat pump type tunnel drying device. A trolley is arranged on a track path of a tunnel, an internal recycling long-shaft fan is arranged in the tunnel, the long-shaft fan comprises a long shaft and blades which are all shaped like a long stripe, and the cross section of each blade is a shaped like a hollow reversed water drop symmetrical to the radial direction and the center of an impeller shaft; the two ends of each blade are inserted into end plates respectively, and the long shaft is connected and fixed with the end plates through spokes; the two ends of the closed type tunnel are provided with an air draft hood and an air intake hood respectively, the air draft hood is connected with a draft fan, and the draft fan is connected with an evaporator through a cyclone dust collector for emptying; the evaporator of a heat pump system is connected with a main machine which is connected with a condenser; an air outlet end of an air blower is connected into an air hood through the condenser; the draft fan and the long-shaft fan impellers are both designed to be of a hollow symmetrical structure, dirt retention does not exist, and lightness, firmness and durability are achieved. According to the cyclone dust removal heat pump type tunnel drying device, heat pump cross flow drying and tail heat recovery are suitable for being adopted by a low-temperature drying system, destroy to heat sensitive components can be prevented, and the system can complete drying, dust removing and heat recovery efficiently with low energy.
