Description
Technical field
The invention belongs to heating system, is the electrical heating conduction oil heating system of a kind of carrying vapour preheater and steam generator specifically.
Background technology
Adopt central heating the steam indirect use hot equipment, in the actual production operation, because fluctuations such as steam pressure, flow and temperature are bigger, thereby cause in the production technology each point temperature wayward, operating difficulties.At present domestic most of steam heating systems are because of the general recovered steam condensed water not of multiple reason, even the former design that has is reclaimed, the actual recovered amount is also very little.Steam heating system is not recycled steam condensate (SC), and the condensed water residual heat resources are lost generally 27%～30%, if steam trap has fault, move malfunctioning, leak, it is big that its heat loss is also wanted.
Adopt the heat-conducting oil furnace of fire coal, fuel oil or combustion gas, boiler thermal output is not high, and a large amount of flue gases that give off can be taken away a large amount of heats, and can cause nitrogen oxide and sulphide staining inevitably, thereby cause thermal pollution, produces waste water, waste gas or waste residue etc.
CN200520031634.X provides a kind of electrical heating conduction oil oil-water-to-water heat exchanger, CN200820087548.4 provides a kind of electrical heating heat-conducting oil furnace device, CN200810037921.X provides a kind of heat supply system for electric heating organic heat carrier, three kinds are used electrically heated conduction oil heating plant, though adopt electrically heated thermal efficiency height, but its shortcoming is that required power consumption is big, and high-grade electric energy is used as thermal source heating conduction oil fully, produce low-grade heat energy heat supply, viewpoint by available energy is seen, and it is uneconomical and integrated heat efficiency is not high, and inadvisable.
Summary of the invention
Deficiency at the prior art existence, the present invention adopts heat-conducting oil heating system closed cycle heating to replace original steam heating system, there is not the discharging heat loss, conduction oil heating network heat loss (generally has only radiation loss) about 5%, so heating efficiency is significantly higher than steam heating system.Single with regard to radiation loss, the conduction oil heating network reduces heat supply loss about 10% than steam pipe system, can economize on coal about 10%.And the employing heating system of hot oil, more remarkable than steam-heating system water-saving benefit.According to statistics, heat-conducting oil heating system is economized on coal than steam-heating system and can be reached 30%～40%.
The technical solution used in the present invention is: a kind of electrical heating heat-conducting oil system with preheater, comprise vapor preheater, with hot equipment, gs-oil separator, hot oil pump and connecting pipe thereof, it is characterized in that: described vapor preheater be provided with electric furnace with hot equipment room, described gs-oil separator receives from carrying out Oil-gas Separation behind the conduction oil of the hot equipment of described usefulness, and the conduction oil of isolating gas enters described vapor preheater after through described hot oil pump pressurization and recycles.
The electrical heating heat-conducting oil system of above-mentioned band preheater, it is further characterized in that: it also is provided with the low level oil storage tank, and described low level oil storage tank is that system is mended into conduction oil by described hot oil pump,
The electrical heating heat-conducting oil system of above-mentioned band preheater, it is further characterized in that: it also is provided with high-order expansion slot, filter, described high-order expansion slot links to each other with described gs-oil separator with filter, after described gs-oil separator carries out Oil-gas Separation, the gas that produces is discharged through high-order expansion slot, and the conduction oil of isolating gas enters described hot oil pump through described filter and recycles.
The electrical heating heat-conducting oil system of above-mentioned band preheater, it is further characterized in that: described electric furnace comprises electrical heating body of heater, electrical heating elements and control element, safety attachment.
The electrical heating heat-conducting oil system of above-mentioned band preheater, it further is characterised in that: it also is provided with steam generator, and described steam generator is by connecting pipe and hot equipment of described usefulness or serial or parallel connection setting.
Condensed water both can be used as heat medium with supplying Process heat, and also available conduction oil produces production as thermal source by steam generator or lives with vapour or hot water.Adopt conduction oil as regulating thermal source, simple and convenient, do not produce condensed water.
The present invention adopts the superheated steam of central heating to heat conduction oil as thermal source, compare with the heating system of direct fire coal, fuel oil or combustion gas, because the steam boiler of central heating generally all adopts cauldron, the thermal efficiency is higher, can save a large amount of energy and reduce the pressure that transports, and reduce the atmosphere pollution that produces in the combustion process.Can save space construction area and be convenient to the management.
Compare with using electrical heating or other conduction oil heating systems fully, the present invention can save power consumption, integrated heat efficiency height, energy-conserving and environment-protective greatly.Need not independently boiler room, utilize main building to get final product reasonable Arrangement equipment, have the factory site of saving, shorten the pipeline distance, reduce advantages such as thermal losses, reduction capital expenditure and production cost.
The present invention can be used for the transformation of original steam heating system, also can be used for newly-built heating system.
