Description
Technical field
The present invention relates to gas sweetening treatment facility, specifically, relate to a kind of centralized Control type sulfur hexafluoride gas purification treatment unit.
Background technology
Pure sulfur hexafluoride (SF
6) gas is colourless, odorless, nontoxic, incombustible gas at normal temperatures and pressures, has excellent insulation characterisitic and arc extinguishing ability, is a kind of desirable dielectric.Along with developing rapidly and the raising of technical equipment of power industry, the electric line construction speed of the voltage levels such as 500kV, 750kV, 1000kV is accelerated, a large amount of sulfur hexafluoride breakers and fully closed combined electric unit constantly drop into be built and operation, and sulfur hexafluoride consumption is increasing.But sulfur hexafluoride can exist more than 3200 year in air, and Greenhouse effect are CO
2more than 23900 times.Sulfur hexafluoride, as a kind of greenhouse gases, is that Kyodo Protocol book is forbidden one of six kinds of gases that discharge.Therefore, the purifying treatment of electric installation arc extinguishing gases sulfur hexafluoride becomes an important topic of environmental transformation.
Meanwhile, because sulfur hexafluoride gas easily ionizable under the factor effects such as electric arc, spark discharge, high temperature decomposes, moisture, oxygen in its degradation production and electric installation react, and mainly generate SO

2etc. toxicity and the extremely strong material of corrodibility, these material corrosion electric installations, reduce apparatus insulated ability, are also detrimental to health.State Grid Corporation of China, to social commitment environmental protection obligation, requires the sulfur hexafluoride in high-voltage electrical apparatus isolating switch, high-tension current inductor must after reclaiming and processing, recharge recycle again, and no longer by this greenhouse gases discharging directly into atmosphere.
At present, manufacturer, in its production process, takes various sulfur hexafluoride gas purifications to process the purity that ensures new gas, is generally purification treatment technology or sub-zero treatment technology.Purification treatment technology comprises valve, adsorption tower and connecting tube thereof, and the medium being cleaned is flowed into by valve in the adsorption tower of filled with adsorbent, after adsorption cleaning, flows out by another valve again.Also be valve, adsorption tower and the conventional mature technology of connecting tube composition industrial circle thereof.
Conventional cryogenics comprises valve, deep cooling container, cryogenic refrigeration system and connecting tube thereof, the medium just needs being cooled is squeezed in deep cooling container by valve, to deep cooling container refrigeration, medium is cooled to after the temperature of needs by cryogenic refrigeration system, then draws medium by another valve.Also be that valve, deep cooling container, cryogenic refrigeration system and connecting tube thereof form the mature technology that industrial circle is conventional.
These technology are all ripe, but its equipment scale is all larger, and are that selectivity is used, and can only carry out dispersiveness reclaim sulfur hexafluoride, and its treatment effect is bad.
For ease of unified detection, centrally managed distribution, the unified management of sulfur hexafluoride gas, requiring to carry out base purifying treatment with State Grid Corporation of China adapts, sulfur hexafluoride gas is carried out to centralized Control and purifying treatment, make gas after treatment reach the new gas standard-required of country, can re-fill operating electric installation, carry out recycling of sulfur hexafluoride gas, just becoming electric installation arc extinguishing gases sulfur hexafluoride purifying treatment problem has an important content to be solved.Also do not have both at home and abroad special, processing power to reach the new gas standard of national sulfur hexafluoride, that level of automation is higher, process the miniaturization centralized Control treatment facility that meets national grid management expectancy.
In addition, in buffered technology, the adsorption tower for the treatment of unit was processed after for some time, humidity or the purity of processing gas will obviously decline, show sorbent material in adsorption tower moisture-saturated or adsorb saturatedly, now cannot again reuse, need to change sorbent material, sorbent material is manually poured out and packed into, and the processing of sorbent material and cost of use are very high.
In deep cooling tail gas separating treatment technology, the deep cooling container liquid level in treatment unit should account for 4/5 left and right of deep cooling container cumulative volume.Along with the decline of refrigeration temperature, in deep cooling container, sulfur hexafluoride liquefies after lowering the temperature gradually, and deep cooling container top sulfur hexafluoride is still gaseous phase.Deep cooling container can be cooled to-80 DEG C, and under nominal situation, now the sulfur hexafluoride in deep cooling container is solid, and a small amount of gas is arranged at top, and deep cooling container internal pressure is lower; In treating processes, impurity in container need to be heated up after subcooling discharge so that liquid hot-metal carburized steel bottle, along with the rising of temperature, sulfur hexafluoride liquefies gradually or gasifies, and now deep cooling container internal pressure raises, and when 30 DEG C of room temperatures, pressure can reach 3MPa left and right.Known deep cooling container is alternation between low-temp low-pressure and High Temperature High Pressure.Sulfur hexafluoride is constantly liquefied to while being full of whole deep cooling container body, if because surprisingly stopping refrigeration or refrigerating duty not or other misoperationes, may make deep cooling container body without remaining space for the gasification expansion of boosting, cause deep cooling container body to break from the weakest place or explosion with pressure release, cause even equipment or loss of life and personal injury of gas leakage.
Be full of the extremity of whole deep cooling container body for preventing that sulfur hexafluoride is constantly liquefied to, adopt easy eyepiece to have explosion danger, and conventional liquid level alarm device all can not use as float-ball type, liquid level float-type etc., it is quick-fried that ball float can be crushed or press, and liquid level float cannot bear; Common utilize medium-gas different from liquid conduction rate come the device of measuring liquid level also not all right.
Therefore, in adsorption tower, the liquid level alarm device of adsorbent reactivation use and deep cooling container is that electric installation arc extinguishing gases sulfur hexafluoride purifying treatment problem has two other important content to be solved.
