Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Fig. 1 Fig. 2, a kind of gasification installation in lighter hydrocarbons production process, vapor enters via vapor import 2 to be pressed from both sides
Set 3, liquid phase light hydrocarbon feedstocks enter gasifier shell by material liquid import 1, and high-temperature vapor transfers heat to gas in collet 3
Change device shell wall side, liquid condition is condensed into after vapor heat release and is discharged by condensed water discharge outlet 9, and is used for into the circulatory system
It is recycled.On the other hand, the liquid phase that the gasifier shell high-temperature wall surface after being heated then transfers heat to inside container is light
Hydrocarbon raw material, liquid phase light hydrocarbon feedstocks are by thermal evaporation, and final gas phase lighter hydrocarbons are by 5 discharge of unstripped gas outlet, to complete entirely to gasify
Journey.
Demister 6 is housed on gasifier shell wall surface top, after the light hydrocarbon feedstocks after gasification are detached from liquid level, inside container
During rising, partial gas condensation liquefaction is had, and from 5 discharge of unstripped gas outlet in the form of droplet, these are small
Drop enters in conveyance conduit and is attached to the junction of pipeline wall surface or pipeline, not only can corrosion pipeline, can also be blocked up when serious
Pipeline is filled in, is caused the accident.Demister 6 is the component for removing these droplets, to guarantee that whole device is safely operated.
It is equipped with liquidometer 8 in heat exchanger side, to monitor the liquid level of liquid phase feed in shell, convenient for regulation in time.
The liquid level of light hydrocarbon feedstocks liquid in gasifier shell should be no more than collet 3 height, when liquid level is excessively high, reduce material liquid into
Enter amount；When liquid level is too low, increase the inlet of material liquid, the operation that entire gasification installation can be made stable in this way.
The core of the utility model gasification installation is the design of the container groove 7 of gasifier wall surface.In entire gasification dress
During setting operation, the presence of many container grooves 7 on wall surface causes heat transfer type on wall surface to be turned by traditional convective heat transfer
Become phase-change heat transfer, and the presence of container groove 7 also makes gasifier part wall thinning, improves heat transfer efficiency.Due to gas
Change device operating condition is low pressure, not high to intensity requirement, so container groove 7 not will cause the reduction of gasifier security performance,
The a large amount of small bubbles generated on container groove 7 in diabatic process instead can aggravate the gasification of liquid phase main body, to improve
Gasifier efficiency.
Form of grooves on gasifier wall surface can specifically have following three kinds：
As shown in Figure 3：Form one：Spherical or ellipsoid connected in star, this groove are symmetrical structure and are evenly distributed on gas
Change device one week, for depth in 3~5mm, width is about 10mm, up and down or control the distance between two grooves 30~50mm it
Between.
As shown in Figure 4：Form two：Wedge-shaped impression, this groove is symmetrical structure and is evenly distributed on gasifier one week,
For its depth in 3~5mm, width is about 10mm, and the distance between upper and lower or two grooves in left and right are between 30~50mm.
As shown in Figure 5：Form three：Combined groove, this groove are symmetrical structure and are evenly distributed on gasifier one
In week, for depth in 3~5mm, width is about 30~50mm, up and down or left and right the distance between two grooves 30~50mm it
Between.
In order to improve the reliability of gasifier wall surface phase-change heat transfer, arrangement of the above-mentioned 3 kinds of container grooves 7 in wall surface longitudinal direction can
For multilayer, generally 10 layers more appropriate, but to be not to be exceeded collet 3 high for the height in most upper one layer of container groove 7, otherwise
The effect of augmentation of heat transfer is not had.On the other hand, entire gasifier wall surface is also not equally hydraulically smooth surface, and it is coarse for should pre-processing
Wall surface.
During phase-change heat transfer, when the degree of superheat is between 10 DEG C~30 DEG C, phase-change heat transfer is in the highest core of efficiency
State fluidized state, so controlling steam temperature in collet 3 during whole device operation, making itself and liquid phase in container
The temperature difference of light hydrocarbon feedstocks saturation temperature is between 10 DEG C~30 DEG C, steam bubble on surface at chamber wall especially container groove 7 at this time
Increase is continuously generated to largely generate, the speed that steam bubble generates also constantly is accelerated.At the same time, in such a state,
The mainstream temperature of light hydrocarbon feedstocks liquid has arrived at and is more than the saturation state temperature under corresponding pressure, therefore all generations
Steam bubble will not reduce condensation or disappearance, will continue to grow up and spread in body material liquid working medium on the contrary.This feelings
Under condition, the steam bubble largely generated can grow up in shell material liquid, beat, and collide, and be crushed, this violent movement increases
The agitation of liquid heat transfer film enhances the progress of heat convection.
The utility model is by utilizing phase-change heat transfer principle, and liquid phase light hydrocarbon feedstocks are heated in kettle, the vapor of high temperature
Liquid phase feed is heated via wall surface of the container in collet 3, due to heating wall temperature and raw material liq saturation temperature it
Between there are temperature difference, this temperature difference is known as the degree of superheat, passes through the temperature adjustable degree of superheat of vapor in control collet 3
Size, when the degree of superheat increases to a certain numerical value, liquid forms steam bubble on certain points of heating surface.These points are known as vaporizing
He Xin ﹐ typically occurs in the irregularity of heating surface, such as groove or pit.After steam bubble is formed on constantly Chang great ﹑ Tuo Li ﹑
Floating, the steam bubble largely generated can grow up in liquid working substance, beat, and collide, and be crushed, and the violent movement such as combination increases liquid
The agitation of body heat transfer, enhances the progress of heat convection.
During entire phase-change heat transfer, the process that steam bubble is formed and grown up can absorb a large amount of disengagings for vaporizing Qian Re ﹐ steam bubbles
Generate violent Rao Dong ﹐ again with ascending motion thus phase-change heat transfer than monophasic fluid heat convection strongly much.For industry
Energy conservation and production it is efficient for, improve heat exchange efficiency, can not only save a large amount of equipment capital investment, but also can recycle more
Waste heat.The efficiency of heat exchange equipment improves 10%, and the utilization rate of entire petrochemical plant energy just can be improved 2%, so energy
Enough designing the efficient gasifier for utilizing phase-change heat transfer has important realistic meaning to modern production demand is met.
