Description

Miniaturized energy-saving distillation plant
Technical Field
The invention relates to a miniaturized energy-saving distillation device pipe, in particular to a miniaturized energy-saving distillation device with high efficiency and energy saving, and belongs to the technical field of daily necessities.
Background
Distillation is a thermodynamic separation process widely used in chemical experiments to separate and purify liquid substances. The method is particularly applied to the following aspects:
(1) when the boiling points of the components in the mixture differ significantly, the liquid mixture is separated.
(2) When the pure compound contains a small amount of impurities, the purity is improved.
(3) Recovering the solvent or concentrating the solvent.
In principle, distillation is a unit operation that utilizes the difference in boiling points of the components of a mixed liquid to vaporize the lower boiling components and recondense to separate the entire components. The distillation operation comprises three parts, namely evaporation, condensation and reception, and the operation of consumed energy comprises two parts, namely, the evaporation link heats liquid to convert the liquid into gas, and the condensation link cools the gas into liquid. Generally, the higher the boiling point of the liquid is, the more energy is consumed in the evaporation link, and the easier the condensation is; the lower the boiling point of the liquid, the less energy is consumed in the evaporation step, and the more difficult the condensation step, the more energy is consumed.
Four types of condenser tubes are often used in chemical experiments: straight condenser pipe, spherical condenser pipe, snakelike condenser pipe, air condenser pipe.
The straight condenser tube comprises an air condenser tube as an inner core and a water cooling tube as an outer sleeve, is cooled by water, is suitable for substances with the boiling point below 140 ℃, and is used for cooling in a distillation device. The straight condenser pipe needs to use water as cooling medium help condensation when using, not only needs to increase water circle device, consumes the energy, also has water pressure variation, the risk of running out water.
The spherical condenser tube is also called as a reflux condenser tube and comprises an inner tube and a water cooling tube, wherein the inner tube and the water cooling tube are connected with a plurality of bulbs, and the water cooling tube is sleeved outside the inner tube and is cooled by water. The cooling surface area is large, and the cooling surfaces are connected in a spherical manner, so that the gas is condensed once in the ascending link, and the liquid is easier to condense, and the method is applied to reflux operation. When in use, the device is matched with a distillation flask and a drying tube so as to condense and reflux steam into the flask. The spherical condenser pipe cannot be used as a condenser pipe in a distillation device because liquid is accumulated at the bulb, the former fraction does not flow out of the condenser pipe, the latter fraction enters the condenser pipe to be mixed with the former fraction, and the two liquids cannot be well separated.
The serpentine condenser tube also includes an inner core and an outer tube, cooled with water. The inner core tube is spiral, the length of the glass tube is increased, and the cooling area is larger than that of a sphere. The inner core pipe is spiral, so that more distillate is accumulated during distillation, and the inner core pipe is suitable for being used as a vertical continuous long-time reflux device, but the inner core pipe is difficult to process and high in price, and cannot be used as a condenser pipe in a distillation device.
The air condensation pipe has only one glass tube and is cooled by air. When the boiling point of the distillation material exceeds 140 ℃, an air condenser can be used to cool the material by utilizing the temperature difference between air and vapor. The common air condenser pipe has low condensing efficiency, is only used when the boiling point of liquid is more than 140 ℃, and has limited application range.
In a general distillation operation process, a straight condensing pipe cooled by water is generally used, so that not only energy consumption is required for condensation, but also a water cooling system is required to be added, so that a distillation device becomes more complicated.
The invention designs a novel air condenser pipe, which utilizes air to cool steam, prolongs the residence time of the steam in the condenser pipe, increases the contact area of the steam and the air, and improves the condensing efficiency and the application range of the air condenser pipe.
Based on the novel air condensation pipe, the invention designs a novel miniaturized and energy-saving distillation device which has several remarkable characteristics compared with the existing distillation device. (1) Only air is used as a condensing medium, so that the equipment is simple and easy to maintain, and the weight of the distillation device is reduced, so that the distillation device is miniaturized and convenient to move; (2) a circulating water cooling system is reduced, energy is saved, and cost is reduced; (3) the operation is simple, the use is convenient, the distillation device is suitable for being used in families, offices and other occasions, and the distillation cost is reduced.
Along with the improvement of living standard of people, the requirement on drinking water is higher and higher, tap water in some areas contains more impurities and has higher hardness, and many people do not like drinking the water. The distilled water has less impurities, and has good functions of penetration, dissolution, diffusion and cleaning, and has effects of promoting or reducing human body blood lipid, immunity, renal function, etc. In order to drink high-quality water, some people directly buy barreled pure water through the market or install a reverse osmosis water treatment device, and other people prefer DIY to prepare distilled water by themselves, however, the existing water distillation device is relatively complex, the cost for preparing distilled water is high, the occupied area is large, and the water distillation device is not suitable for being used in families and offices.

Principle of operation
Distillation is heating to evaporate the low boiling point liquid into gas, and condensing and reducing to form liquid, so as to separate the liquid from the high boiling point substance in the original solution. The heating of a common distillation device consumes a part of energy to convert liquid into gas. Energy is also consumed in cooling the gas, and the lower the boiling point of the vapor, the more difficult it is to cool it into a liquid. For example, a common distillation apparatus used in a chemical laboratory is often cooled by using circulating water as a cooling medium, so that some energy sources are consumed, the distillation apparatus becomes complicated, and much space is occupied. The core of the invention is that the novel air condenser pipe is used, cooling media such as water and the like are not needed, and energy consumption is not needed, so that the distillation equipment is simple and convenient to operate, and the water production cost is reduced.
The common air condenser pipe is cooled by air, has a small application range and is only used when the boiling point of liquid is more than 140 ℃. The reason is that the common air condensation pipe is required to be inclined downwards for receiving condensed liquid, the density of distilled vapor is much higher than that of air, the vapor can quickly flow from the upper part of the condensation pipe to the guide pipe under the action of gravity, the time for staying in the condensation pipe is short, and the contact time with air is short, so the condensation effect is poor.
In order to improve the effect of air condensation, the first method is to prolong the residence time of steam in the condensation pipe, the invention uses a reverse operation method, the steam firstly enters the bottom of the condensation pipe and then flows reversely from bottom to top, the rising speed of the steam is very slow due to the action of gravity, thus the residence time of the steam in the condensation pipe is increased. The specific working principle is as follows.
When the device is used, steam generated in the distillation process enters the bottom of the condensation pipe from the inner pipe through the connecting pipe. Because the lower ground mouth of the condensation pipe is connected with the receiving bottle in a sealing way, the density of the steam is higher than that of the air, and the steam slowly flows from bottom to top from the bottom of the outer sleeve pipe under the action of gravity. The upper part of the outer sleeve is wide, the lower part of the outer sleeve is thin, the upward flowing speed of the steam is further reduced, the heat exchange time of the steam and the air is prolonged, meanwhile, the area of the condensing glass tube is gradually increased, the contact area of the steam and the air is enlarged, and the condensing efficiency of the condensing tube is improved. The vapor condenses into droplets at this point, collects at the bottom of the condenser tube due to gravity, and flows from the straight tube into the receiver flask. In addition, the function of the vent pipe on the upper side of the outer sleeve pipe is to balance the system pressure and prevent the distillation device from forming a closed system.
The air condensation pipe is applied to distillation operation and can cool liquid with the boiling point of more than 70 ℃. Due to the use of the novel air condensation pipe, a cooling water circulation system is eliminated. Compared with the prior art, the invention has the following beneficial effects:
the invention has the beneficial effects that: the air condenser pipe is used in the invention, the structure is simple, the condensation performance can be obviously improved, and the application range is wider. In addition, the condensation process is secondary air condensation, a cooling water circulation system is omitted, other condensation media are not used, energy consumption is low, and the operation cost is reduced. The whole device is simple and compact in structure, the novel air condenser pipe is vertically used, the occupied space is reduced, and the device is more convenient to move and operate. In a word, after the novel air condensation pipe is used, other condensation media are not needed, the energy is saved, the occupied space is reduced, the equipment is simpler, the operation is more convenient, and the novel air condensation pipe has a good application prospect.
