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, for example Novel energy-saving sludge drying system of dewatered sludge in enormous quantities.
Background technology
Along with the quickening of Economic development, population growth and urbanization process and the raising of wastewater treatment rate, the generation of municipal sludge is also increasing, but China's sludge disposal technology and equipment but generally fall 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 with thermal source, mud to be carried out the treatment process of deep dehydration, it can make mud significantly subtract appearance, and volume can reduce 4-5 doubly, product is stable, odorless, without causal organism, sludge product purposes after drying and other treatment is many, can be used as fertilizer, soil improvement agent, substitute energy etc.Conventional sludge drier uses electric heating or the higher-grade energy such as fire coal, oil-firing boiler generation steam, not only consume mass energy, increase carbon emission, and this technology drying temperature is high, large 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, the generation of oil-firing boiler thermal source produces secondary pollution to atmosphere in addition, needs additional gas to pollute processing costs.The another kind of usual way of drying sludge is radiant drying, and its principle, for energy is directly acted on material, can reduce the resistance that internal heat is transmitted, and rate of drying is very fast, but thermo-efficiency is lower, and drying cost and working cost are higher.One-time investment and the working cost of sludge drying are high, have hindered to a great extent application and the popularization of drying sludge, have delayed the process that the small and medium cities sludge of sewage treatment plant is processed.The mud bulk deposition of present many sewage works, caused serious secondary pollution to environment.
Many research papers and patent adopt sun power to carry out sludge-drying in recent years, paper (the greenhouse type sun power drying sludge research of writing such as Wang Chuanqi etc., science and technology Leader 2010,28(22)) analyzed and utilized the solar radiation sludge-drying, pointed out to utilize sun power can make the area of 1 square metre produce 1 ton of drying sludge amount nearly in 1 year.In patent of invention: sun power, high-temperature double heat source heat pump sludge dry system (patent No. zL200710020057.8, Granted publication CN100559103C, 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 wet air simultaneously, thereby reaches the purpose of save energy.Patent of invention for example again: the system (number of patent application 200810059068.1 that utilizes solar energy drying mud, Patent Office of the People's Republic of China) adopt the heat conducting oil type solar energy collector, carry out sludge-drying by the thermal oil by solar heating, also can save dry required portion of energy.Generally, these sun power utilize method generally to be divided into two classes: a kind of employing direct radiation is dry, and the another kind of solar heat collector that adopts is first collected heat energy, resupplies other devices and uses.
But all ignored a realistic problem in these researchs: China's most of area four seasons weather is clearly demarcated, and is large in summer and winter temperature difference, and day alternates with night simultaneously, causes solar source to have unstable and fluctuation problem.Winter, air themperature 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 patent to recycle.Generally speaking, existing device or the method complexity of utilizing solar energy drying, stability and poor reliability, fail to take full advantage of heat energy, and the actual feasibility of implementing is low.
