Description
Technical field
The present invention relates to heat-exchanger rig, relate in particular to a kind of multi-cavity type heat-exchange energy-saving heating plant of flash distillation producing steam.
Background technology
The water spacer conduction oil producing steam heat-exchanger rig of traditional heat-conducting oil furnace, conduction oil circulation heating mode producing steam mode to boil water is too original, and vaporization time is long, and not energy-conservation, speed is slow.The mode of conventional boiler producing steam utilizes burner hearth to heat heating tube, by heating tube, water heated, and this process, relatively static.Because specific heat of water appearance is larger, thermal conductivity is 602mw/cm.cl under conventional subatmospheric.Conventional boiler mode of heating is by burner hearth, and to the steel pipe heating of burner hearth, water is walked steel pipe heat absorption producing steam, this water intrusive mood boiler, and the one, slow, the 2nd, vaporization time is long.The 3rd, meritorious hot biography rate is low.Effective power is between 70%-85%, visible, and the speed of steaming of two kinds of boilers is slow.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, provides a kind of multi-cavity type heat-exchange energy-saving heating plant of flash distillation producing steam.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of multi-cavity type heat-exchange energy-saving heating plant of flash distillation producing steam, it is characterized in that: comprise heat carrier furnace, multi-cavity type steam heat exchanger, water inlet system and heat collection water tank, described heat carrier furnace is connected with waste-heat recovery device, and be connected multi-cavity type steam heat exchanger with pipeline by high temperature oil pump, described water inlet system connects waste-heat recovery device, waste-heat recovery device connects heat collection water tank, described heat collection water tank passes through high-pressure pump, after relief valve, connect a nozzle, described nozzle connects multi-cavity type steam heat exchanger, between described relief valve and nozzle, be provided with check valve, described relief valve connects heat collection water tank by pipeline, between relief valve and heat collection water tank, be provided with check valve, described multi-cavity type steam heat exchanger connects output channel, described output channel is provided with arm and connects heat carrier furnace.
Described multi-cavity type steam heat exchanger is connected and composed by elementary vaporization chamber, second steam intensification heat exchanging chamber and three grades of steam superheating heat exchanging chambers, in described elementary vaporization chamber and three grades of steam superheating heat exchanging chambers, be provided with coil pipe, second steam intensification heat exchanging chamber is provided with comb in upright arrangement.
Described multi-cavity type steam heat exchanger is connected with moisture separation device, Pressure gauge, safety valve and steam stop.
On described nozzle, check-valves is installed.
The present invention utilize conduction oil or the molten conduction firing rate of salt fast, gradient of temperature changes high with boiling point greatly feature, displays the shower nozzle aqueous dispersion of liquefying and becomes corresponding unit volume less, lighter weight, the water smoke between 150mm-200mm by high-pressure atomization.Inject directly on the surface of 280 ° of-300 ° of conduction oil coil pipes of the inherent temperature in the first chamber, the water smoke molecule of 150mm-200mm produces a large amount of water vapours at coil pipe and cavity heat absorption moment, boil-off and do not have vaporization water rapidly under siphonage, the vertical steel pipe inner wall of steel pipe in the rapid conduction oil that is immersed in 280 °-300 ° by the second chamber, the steam of having vaporized in this process and do not have vaporization water done the variation of physical quantity for the third time here, steam pressure is also in quantitative change simultaneously, the steam of vaporization and remaining water are again in pressure-acting and siphonage, flow to the 3rd chamber.Transverse tube is arranged conduction oil cavity, and in this cavity, steam absorbs heat at the conduction oil transverse tube surface collision of 280 °-300, and makes steam turn to superheated steam to change from saturated vapor.In this heat transfer process, in elementary vaporization chamber, in coil pipe, flow heat-carrying agent medium coil pipe and walk atomized water outward, in second steam intensification heat exchanging chamber, in tubulation, flow steam and water row tube outflow heat-carrying agent medium.In three grades of steam superheating heat exchanging chamber inner coil pipes, flow heat-carrying agent medium coil pipe outflow steam.
The present invention's advantage is compared with prior art: the present invention proceeds to multi-cavity type heat exchange steam generator by high temperature circulation pump by conduction oil, by high-pressure atomizing device, water is sprayed in multi-cavity type steam generator again, make water smoke moment flash distillation change into steam, operating efficiency is high, vaporization time is short, the speed of steaming is fast, safe and reliable.
