Description
Technical field
The present invention relates to a kind of dehumidification system, relate in particular to a kind of be applied to dry moist material, the for example new-type energy-saving sludge dehumidification system of dewatered sludge in enormous quantities.
Background technology
Raising along with Economic development, population growth and quickening of urbanization process and wastewater treatment rate; The generation of municipal sludge is also increasing; But China's sludge treatment technology and equipment but generally falls behind; The coverage ratio that the mud safe handling is disposed is very low, becomes the urgent problem that present China faces.
Drying sludge is the treatment process of mud being carried out deep dehydration with thermal source; It can make mud significantly subtract appearance, and volume can reduce 4-5 doubly, and product is stable, odorless, no causal organism; Sludge product purposes after the drying and other treatment is many, can be used as fertilizer, soil improvement agent, substitute energy etc.Conventional sludge drier uses electric heating or high-grade energies such as fire coal, oil-firing boiler generation steam, not only consumes mass energy, increases carbon emission; And it is should the technology drying temperature high; Big with circumstance of temperature difference, exhaust temperature is high, and efficiency of energy utilization is low; Running cost is high, is not suitable for the target for energy-saving and emission-reduction of society's promotion now.Flue gas coal-fired in addition, that the oil-firing boiler thermal source produces produces secondary pollution to atmosphere, needs additional gas to pollute processing costs.The another kind of usual way of drying sludge is a radiant drying, and its principle can reduce the resistance that internal heat is transmitted for energy is directly acted on material, and rate of drying is very fast, but thermo-efficiency is lower, and drying cost and working cost are higher.The one-time investment of sludge drying and working cost are high, have hindered the application and the popularization of drying sludge to a great extent, have delayed the process that the small and medium cities sludge of sewage treatment plant is handled.Present many sludge of sewage treatment plants bulk depositions have caused serious secondary pollution to environment.
Many in recent years RPs and patent adopt sun power to come sludge-drying; For example paper (the greenhouse type sun power drying sludge research of writing such as Wang Chuanqi; Science and technology Leader 2010; 28 (22)) analyzed and utilized the solar radiation sludge-drying, pointed out to utilize sun power can make 1 square metre area produce 1 ton of drying sludge amount nearly in 1 year.In patent of invention: (patent No. zL 200710020057.8 for sun power, high-temperature double heat source heat pump sludge dry system; Granted publication CN 100559103C; Patent Office of the People's Republic of China was authorized on November 11st, 2009) in; Adopt solar energy air heat collector to collect sun power and offer heat pump, heat pump also can reclaim heat in the wet air simultaneously, thereby reaches the purpose of save energy.Patent of invention for example again: the system's (number of patent application 200810059068.1 that utilizes solar energy drying mud; Patent Office of the People's Republic of China) adopts the heat conducting oil type solar energy collector; Through being come sludge-drying, also can practice thrift dry required portion of energy by the thermal oil of solar heating.Generally, these sun power utilize method generally to be divided into two types: a kind of employing direct radiation is dry, and the another kind of solar heat collector that adopts is collected heat energy earlier, resupplies other devices and uses.
But in these researchs, all ignored a realistic problem: China's most of area four seasons weather is clearly demarcated, and is big in summer and winter temperature difference, and day alternates with night simultaneously, causes solar source to have unstable and fluctuation problem.Winter, AT was low in addition, and the air heat energy utilising efficiency is low.On the other hand, the wet air temperature of discharge vaporization is high, and contained available energy is many, does not consider in many researchs or the patent to recycle.Generally speaking, existing device or the method complicacy of utilizing solar energy drying, stability and poor reliability fail to make full use of heat energy, and the actual feasibility of implementing is low.
Summary of the invention

Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described.
Fig. 1 is the entire system structural representation of the embodiment of the invention 1.
As shown in Figure 1, this sludge dry system comprises solar energy greenhouse 12, solar energy collector system 7, heat pump, regenerative apparatus 2 and sludge drying mechanism; Solar energy collector system 7 places solar energy greenhouse 12 roofs, and heat pump, regenerative apparatus 2 and sludge drying mechanism are installed in the solar energy greenhouse 12, and regenerative apparatus 2 is installed in the heat pump pipeline.
Solar energy collector system 7 comprises solar energy collector and vaporizer, and vaporizer places solar energy collector, and vaporizer places after the temperature control valve 6, and is parallelly connected with heat absorption dehumidifying vaporizer 8.Solar energy collector adopts the valve tube of evacuated flat panel type valve tube or arranged in arrays.
System is different with the regular solar hot-water heat collector, and solar energy collector system 7 of the present invention is with evaporator designs structure in aggregates in solar energy collector and the heat pump, can be with the working medium in the solar heating evaporation device of collecting.Solar energy collector system 7 is main thermals source of heat pump, for drying sludge provides heat energy.Solar energy collector system 7 ability effective collection solar radiant energies also convert heat energy into, through being arranged in vaporizer wherein, give heat pump with thermal energy transfer.Solar energy collector system 7 can adopt the evacuated flat panel type also can vacuum tube type, through arranged in arrays, improves the received radiation area, adopts effective thermal insulation layer simultaneously, guarantees that the radiating capacity of the sun is farthest changed, and improves assimilated efficiency.
Heat pump comprises heat pump compressor 1, condensing surface 4, heat pump throttling valve 5, heat pump circuits 9, heat absorption dehumidifying vaporizer 8 and places the vaporizer of solar energy collector; Heat pump compressor 1, condensing surface 4, heat pump throttling valve 5, heat absorption dehumidifying vaporizer 8 are connected through heat pump circuits 9 with the vaporizer that places solar energy collector; Heat absorption dehumidifying vaporizer 8 and the vaporizer that places solar energy collector be for being connected in parallel, and is arranged in the flow that temperature control valve 6 control working medium after the throttling valve get into heat absorption dehumidifying vaporizers 8 and place the vaporizer of solar energy collector.Heat absorption dehumidifying vaporizer 8 is provided with discharge structure, compares with vaporizer in the common air-conditioning system, and size is bigger.Reason is: sludge drying mechanism is discharged and is contained the very high hot and humid gas of moisture in a large number; When getting into the heat absorption dehumidifying vaporizer 8 of heat pump; Because the evaporator surface temperature is lower than the gas dew point temperature, with under the water condensation, has absorbed the latent heat of liquefaction of water vapour at evaporator surface simultaneously; Make the heat energy that sludge-drying consumed obtain reclaiming, the water vapor that sludge-drying produces will be discharged outdoor with the form of liquid water.
The working medium that circulates in the heat pump has absorbed the solar thermal energy of collecting in heat and the solar energy collector system 7 in the hot and humid gas that sludge-drying discharges in heat absorption dehumidifying vaporizer 8; Flash to short steam from low-pressure liquid working medium; Be delivered to the steam that heat pump compressor 1 supercharging becomes HTHP through heat pump circuits 9, get in the condensing surface 4 through heat pump circuits 9, the working medium of HTHP discharges heat and contains wet mud; Itself then becomes high-pressure liquid from condensation of gas working medium; Through becoming the low-temp low-pressure fluid behind the heat pump throttling valve 5, continue to absorb the heat that vaporizer provides, heat drying mud so repeatedly circulates.
