Description
Technical field
The utility model relates to the tourie of high-order expansion drum emptying end gas in a kind of deep fat heat transfer system
Background technology
Existing heat transfer medium has multiple, and electrical heating is used few because of cost issues is general.The hot water heating generally is used for low temperature situation.Steam Heating is because the vapour source is easy, easy to use, and expense is lower, so be the heating agent that often adopts.But the temperature of steam more than 200 ℃ the time, along with the rising of vapor (steam) temperature, steam pressure also rise sharply (seeing table 1) this will bring very big trouble to system.
Table is saturated-steam temperature, pressure corresponding tables more than 1:200 ℃
The requirement heat medium temperature is often arranged 250 ℃～300 ℃ situation in the practical application.It is inappropriate adopting saturated vapor under the obvious this operating mode.The condensed water of steam heating agent generation must fully be recycled in addition.Otherwise with loss part heat.It is simple, reliable, the most economic scheme that temperature adopts thermal oil system 250 ℃～300 ℃ heating agent operating modes.
Thermal oil system is used extremely wide, at chemical industry, and weaving, food, grease, plastics, many industries such as rubber all are widely used.Adopt the deep fat heating agent its unique advantage to be arranged than electricity, hot water, steam heating agent.
The deep fat heating agent mainly contains two kinds: the one, and biphenyl, biphenyl ether and composition thereof (give birth in the road).Be to be the pure carbon hydrogen compound (conduction oil) of main composition with Fluhyzon in addition.
Above-mentioned two kinds of thermophores have multiple different trade names owing to composition is different with processing method, its use occasion and price also have very big-difference, only the heat-conducting oil system that often runs into are narrated below.It is good that conduction oil has a heat-conductive characteristic, and Heat stability is good does not cause corrosion to heater.Vapour pressure is moderate in the maximum permissible service temperature scope, and the pressure build-up rate is little, and evaporation loss is few, and freezing point is lower, advantages such as aboundresources.
It is 300 ℃, 325 ℃, 340 ℃ three kinds that present homemade conduction oil mainly contains applying working condition.For guaranteeing that avoiding its service life rough sledding such as Yin Re decomposes, condensation that general actual serviceability temperature takes place is advisable for low 20 ℃ than the permission serviceability temperature.
The heat-conducting oil system flow process is seen Fig. 1, and this flow process is the generalized flowsheet that present heat-conducting oil system supplier recommends basically, also is the normal process that present domestic factory uses.
Fig. 1 flow process is by the closed circuit forced circulation system of conduction oil circulating pump 2 as motive force.The low temperature conduction oil advances heating furnace 1 by pump discharge and heats up; High-temperature hot oil after the intensification goes with hot equipment 5; Low temperature deep fat after the use returns circular-pump 2 again, moves back oil when 3 conduction oil low level oil storage tanks are as system shutdown among the figure and uses, and 4 conduction oil filling pumps are as driving and repairing at ordinary times first; 6 gs-oil separators are as the circulating hot oil Oil-gas Separation, and 7 high-order expansion drums are breathed balance as whole system.
To the deep fat flow process, we mainly discuss the tail gas emptying problem of high-order expansion drum.
High-order expansion drum is systems stabilisation pressure and the oily air that in heating process, is discharged of eliminating, the visual plant of the normal quiet run of assurance system.It is above high-order that high-order expansion drum requires to be installed in the hot equipment 2m of the highest usefulness.Its dischargeable capacity V

The systemic circulation amount is generally by calculating with the thermic load amount when the import and export deep fat temperature difference is 20 ℃～30 ℃.We in actual design and use when the circulating hot oil temperature be 260 ℃～280 ℃ high-order expansion drum volumes be the systemic circulation amount 1/40 the time, the actual measurement expansion drum in oily temperature be about 80 ℃.
High-order expansion drum will receive heat when deep fat heats up in the system to rise in system's operating process and the oil mass that has more, also wants the low and short oil mass when leaking of replenishment system oil temperature drop, will discharge the air of carrying secretly in the system simultaneously, must will lead to atmosphere emptying.Problem also takes place thereupon.Because saturated vapor pressure is about 0.0009MPa during 80 ℃ of conduction oil temperature, vapour density is 0.011Kg/m
3. therefore high-order expansion drum is successively discharged a small amount of conduction oil steam in normal running, not only causes damage but also surrounding environment is polluted.Although blast pipe is at high altitude discharge, conduction oil sends offensive odour still to be difficult to accept.We take nitrogen envelope mode to handle to this unfavorable condition.
High-order expansion tank deck is set up nitrogen envelope system and can be avoided a jar interior conduction oil ingress of air to reduce the adverse consequences that conduction oil produces because of air oxidation.The gas that makes the emptying of expansion tank deck simultaneously is the gaseous mixture of nitrogen and conduction oil saturated vapor.This also corresponding suitable loss that part conduction oil saturated vapor leaks and causes that reduced.This mode just part is reduced the loss and is not had thoroughly solution also will increase nitrogen envelope system in addition.
Summary of the invention
The purpose of the utility model provides the tourie of the high-order expansion drum emptying end gas of a kind of deep fat heat transfer system, and this jar can solve waste and the pollution that causes because of emptying end gas, reaches the requirement of energy-saving and emission-reduction, has favorable economic benefit and social benefit.。
For reaching the foregoing invention purpose, the utility model adopts following technical scheme:
The tourie of high-order expansion drum emptying end gas in this deep fat heat transfer system; It comprises: tank body, tank body are provided with the tail gas inlet tube that is connected with existing high-order expansion drum blow-down pipe, and the tail gas inlet tube inserts below the oil level; The oil inlet that fuel outlet joins bottom existing high-order expansion drum; Put the clean oil export of using during long term stop, liquid level gauge is housed, blow-down pipe on the tank body.
