Description

It is a kind of to be easily manipulated the totally-enclosed sludge drying system of providing multiple forms of energy to complement each other used
Technical field
It being easily manipulated the totally-enclosed sludge drying system of providing multiple forms of energy to complement each other used the utility model is related to a kind of.
Background technology
Urban sewage treatment plant sludge moisture control is 60% hereinafter, being to carry out the minimum of Sludge landfill, compost etc. to want It asks, is also the starting point that recycling sludge utilizes.Although the technical method used in country's sludge of sewage treatment plant desiccation at present can take Desiccation effect centainly, but the problems such as generally existing equipment investment is big, high energy consumption, operating cost are high or is limited by place.Cause This, a kind of efficient sludge drying mode of searching is a hot issue of current sewage treatment industry concern, and dirty It is badly in need of the Important Problems solved in mud disposal process.Solar energy and heat pump techniques are as green clean energy resource and renewable energy Source efficient technique of rainwater utilization is applied in traditional desiccation industry, can significantly reduce its energy consumption, but solar energy is mutually tied with heat pump The technology for carrying out sludge drying is closed still in the starting stage, the sizable application of the technology is realized, also need further to study.
In traditional drying equipment, convection current desiccation is simple in structure with its, easy to operate, adaptable generally to be answered With being most commonly used a kind of drying equipment in current production.The shortcomings that convection current desiccation is that the thermal efficiency is very low, generally only 30% ~60%, the main reason is that due to the direct emptying of drying process exhaust gas, not only wasted caused by exhaust gas takes away waste heat, but also Also it polluted environment.Although a part of waste heat can be recycled using portion cycle in a small number of convection current desiccation, by useless The limitation of gas internal circulating load, is typically only 20%~30%.Although part sensible heat in exhaust gas can be recycled with conventional heat exchanger, In exhaust gas 60%~80% heat be in the form of latent heat existing for, be still discharged.Latent heat therein is recycled, it is just necessary Exhaust gas is cooled to dew-point temperature hereinafter, also to make the latent heat of recycling that there is temperature quality appropriate simultaneously, is used further to desiccation Journey.Realize this process, it is necessary to utilize heat pump assembly.
Heat pump is the device using a kind of clean energy-savings of low-temperature heat sources such as water, air and various waste heats.Heat pump can be from Natural environment or residual heat resources heat absorption can save heating, air-conditioning, confession to obtain output thermal energy more more than input energy Primary energy needed for hot water and industry heating.It is very in the ratio of industrial aspect application heat pump compared with Application in Building heat pump Small, applicable industry heat pump will fully develop talents to reduce CO2 emission.Heat pump is most effective hot using energy offer The method of amount and cold, because it can control humidity and temperature can be arbitrary adjustable at -20 DEG C~100 DEG C, can be good at meeting Desiccation requirement.It needs to carry out in high temperature when some sludge material desiccation, but needs in many biological products desiccation relatively low Desiccation temperature, heat pump can be very good to meet desiccation requirement, so having great potentialities using heat pump desiccation.Heat pump itself will not picture Boiler generates heat like that, but heat can be increased to high-temperature position by it from low temperature position, and the Wen Sheng of heat pump is its output temperature And the difference of heat source temperature.Heat-pump apparatus is compared with conventional convection current desiccation and is had in terms of sludge drying:Save energy consumption, desiccation item Part adjustable extent is wide, saves drying time, advantages of environment protection.
Combined solar energy heat pump UTILIZATION OF VESIDUAL HEAT IN sludge drying system can by solar heat desiccation run energy expenditure it is low and Heat pump desiccation apparatus advantage stable and reliable in work is combined together.Residual heat resources are abundant and when stablizing, preferentially utilize more than outside Heat carries out preheating and heating early period;When solar radiation condition is good, solar heat collector is allowed to play a role as far as possible;Weather condition It is when poor, then main that sludge drying is carried out by heat pump system using electric energy.Since its more conventional air-flow sludge drying disappears in the energy Consumption and dewatered sludge have a clear superiority at we, and the combined solar energy heat pump UTILIZATION OF VESIDUAL HEAT IN technology of providing multiple forms of energy to complement each other has become one kind Novel energy-saving environment-friendly technology.
