Description
Technical field
The present invention relates to a kind of comprehensive utilization waste heat of plant to carry out the device that fractionation is dry and generates electricity, and passes through the second class and absorbs
The waste heat of recycling is carried out step by organic cooperation of formula heat pump system, fractionating system, organic rankine cycle system and drying system
It utilizes.Belong to field of energy utilization.
Background technique
Petrochemical Enterprises in process of production, are inevitably generated a large amount of waste heats.The low temperature exhaust heat of Petrochemical Enterprises mainly divides
It is distributed in atmospheric and vacuum distillation, catalytic cracking, delayed coking, the low temperature exhaust heat of this three parts accounts for about the 60% of full factory's low temperature exhaust heat total amount
~80%.Unemployed low temperature exhaust heat is eventually discharged into environment in a variety of manners in production process, becomes waste heat,
It mainly passes through following four approach and discharges: air cooler dumps, intermediate products tank dumps, flue gas system dumps and circulating water
System dumps.The low temperature exhaust heat that wherein circulating water cooling system dumps accounts for about the 80% of full factory's low temperature exhaust heat.It is produced in production process
Raw low temperature exhaust heat is discarded in a variety of manners, and some devices for needing Low Temperature Thermal, equipment consume a large amount of steam.According to system
Meter, the energy utilization rate in China only about 30%, and the energy utilization rate of Japan is 60% or more, a major reason is just among these
It is not make full use of the low temperature exhaust heat generated in production process.This status had both caused the repetition and waste of the energy, and to ring
Border produces thermal pollution.Therefore the recycling of low temperature exhaust heat is researched and analysed, there is very actual meaning.
Municipal sewage treatment has become various regions and knows together, however the place of the remaining high density pollution object (sludge) of sewage treatment
Reason, just gradually obtains the attention of various countries in recent years.According to the technique of current most of sewage plant, every processing 1t sewage can be generated
The wet mud of 1kg or so moisture content 80%.This sludge can be burned with direct burning process, however, to ensure that the stabilization of sludge
Burning, generally all needs to mix people's auxiliary fuel (coal or oil), and efficiency of combustion and the thermal efficiency are all lower, therefore overall cost compares
It is high.If burnt again after wet mud is dried, when moisture content is less than 35%, calorific value will increase to 6.28~10.5MJ/
Kg can realize stable burning relatively conveniently.Therefore, how to realize drying, obtain extensive attention.
Drying system can simply be divided into heat source and final dryer device two large divisions, the stability and warp of different modes
Ji property has very big difference.The selection of heat source is largely determined by energy prices, from the point of view of the various feasible programs of Treatment of Sludge, uses
Waste heat, in conjunction with the energy of sludge after drying itself, as comprehensive energy scheme, cost is relatively low.If as city totality portion
Administration, can suitably establish some power generation projects, take into account heat source needed for providing Treatment of Sludge.Many papermaking, leather, chemical industry enterprise
Industry has the sewage treatment capacity of itself, but it is uneconomic for building power plant to handle its residual sludge.If
Aqueous 75% or more sludge is transported to nearest sludge treatment plant, can also face a series of logistical problem.And it builds small
The moisture content of sludge is reduced to 35% hereinafter, becoming graininess substantially by type sludge drier, and subsequent packaging is stacked just
Can be relatively convenient, logistics is easy tissue.
