技术领域technical field
本实用新型涉及气体充装领域技术，尤其是指一种高压CO2液体小型储罐供给装置。The utility model relates to the technology in the field of gas filling, in particular to a supply device for a small high-pressure CO2 liquid storage tank.
背景技术Background technique
CO2液体即液态二氧化碳，液态二氧化碳指的是高压低温下将二氧化碳气体液化为液体形态。液态的二氧化碳是一种制冷剂，可以用来保藏食品，也可用于人工降雨。它还是一种工业原料，可用于制纯碱、尿素和汽水。CO 2 liquid is liquid carbon dioxide, and liquid carbon dioxide refers to the liquefaction of carbon dioxide gas into a liquid form under high pressure and low temperature. Liquid carbon dioxide is a refrigerant that can be used to preserve food and can also be used for artificial rainfall. It is also an industrial raw material, which can be used to make soda ash, urea and soda.
在日常生活中，各种气泡水的制备需要使用到小容量气瓶，其中充装的便是高压CO2液体，为此，在工业生产中，需要对小容量气瓶进行高压CO2液体充装。In daily life, the preparation of various sparkling water requires the use of small-capacity gas cylinders, which are filled with high-pressure CO 2 liquid. Therefore, in industrial production, it is necessary to fill small-capacity gas cylinders with high-pressure CO 2 liquid. Pack.
目前，高压CO2液体在小容量充装过程中，由于充装容量不大，具有高频次、低流速特点，高压CO2液体在低流速状态下，流程越长，高压CO2液体就越容易产生气化现象，一旦管道中产生气化，小容量气瓶内便充入高压CO2气体，对高压CO2液体的充装效率将会急剧下降，由于高压CO2气体占据了小容量气瓶内部的一定容量，使得小容量气瓶内的高压CO2液体重量无法达标。At present , during the small-capacity filling process of high-pressure CO 2 liquid, due to the small filling capacity , it has the characteristics of high frequency and low flow rate. It is easy to produce gasification phenomenon. Once gasification occurs in the pipeline, the small-capacity gas cylinder will be filled with high-pressure CO 2 gas, and the filling efficiency of high-pressure CO 2 liquid will drop sharply, because the high-pressure CO 2 gas occupies the small-capacity gas cylinder A certain internal capacity makes the weight of the high-pressure CO liquid in the small-capacity gas cylinder unable to reach the standard.
现有技术中，为提高CO2液体的充装效率，需要采用供给装置，目前的供给装置仅由增压机构组成，利用增压机构将充装管道中的压力提升，提升管道中CO2液体的流速，减少在CO2在充装过程中的气化现象对充装效率的影响，然而，仅采用增压机构依然不可避免地往小容量气瓶内充入CO2气体，并且，一个增压机构仅能对一个小容量气瓶进行充装，充装效率依然无法有效提升，以及，由于小容量气瓶内充入CO2气体，使得小容量气瓶的内部压力增压，从而增加了增压机构的工作负荷，缩短了增压机构的使用寿命。因此，有必要对目前的供给装置进行改进。In the prior art, in order to improve the filling efficiency of CO2 liquid, it is necessary to use a supply device. The current supply device is only composed of a booster mechanism, which uses the booster mechanism to increase the pressure in the filling pipeline and lift the CO2 liquid in the pipeline. The flow rate can reduce the impact of CO 2 gasification on the filling efficiency during the filling process. However, it is still inevitable to fill the small-capacity gas cylinder with CO 2 gas only by using a booster mechanism, and an increase The pressure mechanism can only fill a small-capacity gas cylinder, and the filling efficiency still cannot be effectively improved, and because the small-capacity gas cylinder is filled with CO 2 gas, the internal pressure of the small-capacity gas cylinder is pressurized, thereby increasing the The working load of the supercharging mechanism shortens the service life of the supercharging mechanism. Therefore, it is necessary to improve the current supply device.
