Description
Technical field
Quick-fried method of controlling security is dodged the present invention relates to a kind of acid water storage tank of combined type prevention.
Background technology
Sour water tank gas-phase space contains a large amount of fuel gas, exists when mixed combustible gas bulk concentration is reached after finite concentration
Dodge quick-fried possibility, sour water tank dodges quick-fried accident and happened occasionally, industrial existing operating method be passed through into tank it is largely lazy
Property gas, but when inflate, punching is how many suitable still unknowable.《Oil plant acidity water storage tank accident analysis and processing》[Wang Xianwei,
《China Reconstructs's information:Water and wastewater industry market》, 2009] in describe in the most common failure of sour water tank, sour water tank due to nitrogen envelope
Failure, which causes air to enter the accident for triggering sudden strain of a muscle quick-fried, also generation.
The content of the invention
The technical problems to be solved by the invention are that there is provided a kind of new combination for the problem of security is poor in the prior art
The acid water storage tank of formula prevention dodges quick-fried method of controlling security.This method has the preferable advantage of security.
To solve the above problems, the technical solution adopted by the present invention is as follows：A kind of acid water storage tank of combined type prevention dodges quick-fried
Method of controlling security, to acid water storage tank gas phase composition analyze, obtain gas phase composition content, fuel gas is returned
One change is handled, and the fuel gas composition for preparing different proportion carries out limiting oxygen concentration test, when sour water tank gas-phase space oxygen
Volume content is passed through inert gas when being higher than 6% and is diluted, and when oxygen volume content is higher than 9%, Water spray is opened；Oxygen
When volume content is less than 9%, Water spray is closed, when oxygen volume content is less than 6%, and inert gas stops pouring.
In above-mentioned technical proposal, it is preferable that inert gas is nitrogen, argon gas, preferably nitrogen.
In above-mentioned technical proposal, it is preferable that fuel gas includes hydrogen sulfide, hydrogen, hydro carbons.
In above-mentioned technical proposal, it is preferable that the hydro carbons includes methane, ethane, propane, normal butane, C5.
In above-mentioned technical proposal, it is preferable that limiting oxygen concentration test is 9-11%.
In above-mentioned technical proposal, it is preferable that Water spray is fire demand water with water.
On the basis of domestic refinery's sour water tank, inert gas has been obtained by experimental study in investigation and analysis by the present invention
The oxygen content not fired, i.e. limiting oxygen concentration LOC, meanwhile, research finds that the presence of water vapour can reduce fire explosion
The possibility of generation, therefore, increases tank deck Water spray measure, quick-fried risk is dodged to reduce, control and water spray by oxygen content
The combined use of two kinds of measures is drenched, can effectively prevent sour water tank and occur to dodge quick-fried risk, achieve preferable technique effect.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the method for the invention.
In Fig. 1,1. inert gas pipelines；2. oxygen conten analyser；3. breather valve；4 Water sprays；5 sour water tanks；6 refineries
DCS (dcs).
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Embodiment
【Embodiment 1】
A kind of acid water storage tank of combined type prevention dodges quick-fried method of controlling security, as shown in figure 1, choosing the storage of typical acid water
Tank is analyzed its gas phase composition, and obtaining gas phase composition content, for example table 1 shows, fuel gas is normalized, prepared
The fuel gas composition of different proportion carries out LOC (limiting oxygen concentration) tests.
The fuel gas volume content of table 1
The LOC of gas phase composition is obtained between 9%-11%, to prevent the generation of blast accident, it is proposed that control oxygen volume
Content is passed through nitrogen and is diluted, work as oxygen below 6% when sour water tank gas-phase space oxygen volume content is higher than 6%
When volume content is higher than 9%, Water spray is opened；When oxygen volume content is less than 9%, Water spray is closed, and oxygen volume content is low
When 6%, nitrogen stops pouring.
【Embodiment 2】
A kind of acid water storage tank of combined type prevention dodges quick-fried method of controlling security, as shown in figure 1, choosing the storage of typical acid water
Tank is analyzed its gas phase composition, and obtaining gas phase composition content, for example table 1 shows, fuel gas is normalized, prepared
The fuel gas composition of different proportion carries out LOC (limiting oxygen concentration) tests.
The fuel gas volume content of table 2
The LOC of gas phase composition is obtained between 9%-11%, to prevent the generation of blast accident, it is proposed that control oxygen volume
Content is passed through nitrogen and is diluted below 6.5% when sour water tank gas-phase space oxygen volume content is higher than 6.5%, when
When oxygen volume content is higher than 10%, Water spray is opened；When oxygen volume content is less than 10%, Water spray is closed, oxygen volume
When content is less than 6.5%, nitrogen stops pouring.
【Embodiment 3】
A kind of acid water storage tank of combined type prevention dodges quick-fried method of controlling security, as shown in figure 1, choosing the storage of typical acid water
Tank is analyzed its gas phase composition, and obtaining gas phase composition content, for example table 1 shows, fuel gas is normalized, prepared
The fuel gas composition of different proportion carries out LOC (limiting oxygen concentration) tests.
The fuel gas volume content of table 1
The LOC of gas phase composition is obtained between 9%-11%, to prevent the generation of blast accident, it is proposed that control oxygen volume
Content is passed through nitrogen and is diluted, work as oxygen below 6% when sour water tank gas-phase space oxygen volume content is higher than 6%
When volume content is higher than 9%, Water spray is opened；When oxygen volume content is less than 9%, Water spray is closed, and oxygen volume content is low
When 6%, nitrogen stops pouring.
Obviously, the present invention has obtained the oxygen content that inert gas is not fired, i.e. limit oxygen by experimental study and contained
Measure LOC, meanwhile, research find water vapour there is a possibility that can reduce fire explosion, therefore, increase tank deck Water spray
Measure, dodges quick-fried risk to reduce, by the combined use of two kinds of measures of control and Water spray of oxygen content, can effectively prevent acid
Property water pot occur to dodge quick-fried risk, achieve preferable technique effect.
