Embodiment:A kind of heat pump assembly of sludge drier
Shown in attached drawing 1, which is located at 13 lower section of conveying device for being used for transmission sludge, the heat pump assembly Including First Heat Exchanger 1, the second heat exchanger 2, evaporator 3 and condenser 4;The First Heat Exchanger 1 is used to store thermal energy, the It is equipped with the first air-supply passage 9 and the second air-supply passage 10 in one heat exchanger 1, the first air-supply passage 9 has the first air inlet 5 and the One air outlet 6, the second air-supply passage 10 have the second air inlet 7 and the second air outlet 8;Second heat exchanger 2 is for cooling down Water removal, the second heat exchanger 2 are located at 1 below First Heat Exchanger, and First Heat Exchanger 1 is specially energy-saving heat exchanger, the second heat exchanger 2 tool Body is surface cooler;The evaporator 3 is removed water for cooling down, and evaporator 3 is located at the side of First Heat Exchanger 1;The condenser 4 is used In heating air, condenser 4 is located at the other side of First Heat Exchanger 1;
Second heat exchanger 25 is connected by the first air-supply passage 9 with First Heat Exchanger 1 at the first air outlet, described Third air-supply passage 11 is equipped between evaporator 3 and the second heat exchanger 2, evaporator 3 passes through the third air-supply passage 11 and the Two heat exchangers 2 are connected, and the evaporator 3 is connected by the second air-supply passage 10 with First Heat Exchanger 1 at the second air inlet 7, The condenser 4 is connected by the second air-supply passage 10 with First Heat Exchanger 1 at the second air outlet 8.Heat pump assembly further includes The side in the condenser 4 is arranged in pressure fan 12, the pressure fan 12.
There are one babinet, First Heat Exchanger 1, the second heat exchanger 2, evaporator 3 and the settings of condenser 4 to exist for heat pump assembly tool In babinet, they are set to by each small interior after holder and thermal insulation board segmentation.Gas circulating flow direction is in babinet:A points → B points → C points → D points → E points → A points.H indicates that the water outlet of the second heat exchanger 2, G indicate the water inlet of the second heat exchanger 2.
Its operation principle be by heat pump compressor, gaseous working media be collapsed into high temperature, high pressure gas, into Enter 4 heat release of condenser, the working media of high temperature becomes the liquid of high pressure after being condensed by condenser 4, the work of high-pressure liquid is situated between Matter flashes to gaseous state after expansion valve in evaporator 3, and absorbs a large amount of thermal energy, and gaseous working media passes through heat pump again Compressor, so continuous heating and cooling cycle;Meanwhile the air of supply air system when condenser 4 by being heated to 80 DEG C, 80 DEG C of heated dry air is sent by pressure fan 12 and carries conveying device 13(That is automatic delivering belt)Baking oven, it is xeothermic Air is absorbed heat by the sludge on conveyer belt and evaporated, meanwhile, heated dry air passes through moisture absorption when sludge so that heated dry air becomes At damp-heat air, temperature drops to 55 DEG C or so;55 DEG C of damp-heat airs are passed through First Heat Exchanger 1(That is energy-saving heat exchanger), Thermal energy storage is got up, while temperature drops to 45 DEG C or so.Then pass through the second heat exchanger 2(That is surface cooler), wet at this Water from steam steam contacts the fin surface in dew-point temperature the second heat exchanger 2 below, and droplet drippage is congealed into heat release.Release heat It is taken out of through 2 interior media of the second heat exchanger, heat is dispersed with water-cooling pattern or air cooling way outside cabinet, cooling medium is again Enter from the water inlet of the second heat exchanger 2, cycle.After 45 DEG C of humid air, which enter evaporator 3, to be condensed, after humid air moisture condensation It is discharged, saturation cold air is sent to First Heat Exchanger 1, absorbs the thermal energy stored in First Heat Exchanger 1, and temperature is gone back up to rapidly It 45 DEG C or so, enters back into condenser 4 and is heated to 80 DEG C.So constantly cycle constantly dries sludge.
Second heat exchanger 2 is put in 1 lower section of First Heat Exchanger, and since B points are warm and humid and the warm and humid difference of outdoor environment is smaller, heat is handed over The amount of changing is smaller, can always be run with random groups, stablizes and takes away heat in babinet, keeps internal temperature field balance simultaneously, reduces Into 3 fin gas humiture of evaporator so that evaporation is in lower temperature range, extends the service life of compressor.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this. It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover the scope of protection of the utility model it It is interior.
