Description
Technical field
The invention belongs to the saturated vapor separation field, particularly a kind of flash separator of pressure more than super-pressure that be applicable to.
Background technology
Flash evaporation technology is the comparatively general technology of a kind of application in the industrial production, and it is widely used in industry-by-industries such as chemical industry, electric power, weaving, light industry.After the hydrophobic pressure of heat reduces, will discharge flash-off steam.Flash separator is exactly a kind of device that the decompression of hydrophobic or boiler water under the certain pressure is carried out the double evaporation-cooling vaporization and separated, and its resulting steam is generally saturated vapor.Because flash separator is typically designed to tank structure, so also claim flash tank.
Flash separator is a kind of important energy saving device, is usually used in boiler blow-off and hydrophobic waste heat recovery.Hydrophobic or boiler blowdown water enters in the jar, according to fluid two phase flow and eddy current separation theorem, in jar after the dilatation, pressure reduces, can produce flash steam in jar, this steam is introduced the low-pressure steam pipeline or by pressure pipe road in the injector pressurization back introducing, is entered the hot equipment of using; The saturated condensate water that accumulates in the tank body bottom is discharged, and gets back to deoxygenation water tank heated feed water behind drain valve, can make original inferior heat energy obtain again utilizing.
The research of flash evaporation technology both at home and abroad mainly concentrates on according to different application backgrounds with utilizing, under the low pressure condition, flash system and key equipment are optimized design, especially at aspects such as residual heat of electric power plant recovery, heat integration, aluminium oxide manufacturing, dairy products processing, desalinizations, use more general.
Along with expanding economy, some industry has proposed demand to the small-sized industrial boiler of super-pressure and subcritical parameter.In petroleum industry, in the oil extraction later stage, the viscosity of crude oil significantly rises, and buried depth also progressively increases, and this has just caused the very big difficulty of oil extraction, needs to adopt the very high steam of pressure to feed and exploits after oil well softens dilution to crude oil; Also need be with the steam of a spot of super-pressure, subcritical even supercritical pressure when carrying out valves test just like in the nuclear power station; Startup boiler in the thermal power station, in the chemical industry in the production technology of some special plastic, spinning, it is very high all to need to use pressure in addition, and flow is little steam again, all these all make small-sized subcritical, superpressure boiler have considerable market prospects.But when producing steam, will produce the higher sewer of a considerable number of salt concentration and hydrophobic simultaneously, therefore how effectively utilize these high-grade heat energy, be exactly the problem that we must solve.
At the uphole steam generator UTILIZATION OF VESIDUAL HEAT IN, Qingdao University of Science and Technology has carried out correlative study, utilize the HTHP waste water of uphole steam generator discharging, use flash evaporation technology to generate electricity in conjunction with the back pressure type saturated steam turbine, and having designed a cover miniaturization flash distillation dilatation electricity generation system, a whole set of flash distillation dilatation electricity generation system is made up of flash tank, saturated vapor turbine, generator, pump, heat exchanger, Pressure gauge and pressure control valve etc.The effect of flash tank is exactly the saturated vapor that 8.5MPa, 295 ℃ high-temperature water step-down is obtained low pressure in this system.The flash tank water inlet is entered by end socket, and the bottom is bearing and sewage draining exit, and steam (vapor) outlet is in flash drum overhead, and wire mesh demister is set carries out carbonated drink separation, and the opposite side of end socket is the liquid level post, and Pressure gauge and thermometer all are installed in the top.This flash tank structure is because the restriction of volume is only welded a steel plate to guarantee the flash distillation effect in the exit.In running, because lateral intake also directly impacts steel plate, will produce the tank body vibrations inevitably, the big phenomenon of noise stays potential safety hazard.And its horizontal type structure causes sewage draining exit and the outstanding tank body of steam (vapor) outlet, has increased setting height(from bottom), makes the Pressure gauge and the thermometer that are installed on the top be difficult to on-the-spot reading.In addition, this type flash separator is pressed intake pressure 8.5MPa design, so it suits to use under low, medium-pressure boiler service condition, for present oil field gas injection super-pressure commonly used, subcritical or super critical boiler, still exist the energy separative efficiency of successively decreasing low, noise and vibration are bigger, and have defective such as potential safety hazard.
