Abstract
This invention declares a parallel operation method of gas tank in which two or more gas tanks are deployed in parallel with one or several working tanks and one or several spare ones. The mentioned gas tanks are wet tanks with the pressure of 5-9 kPa. The gas in storage is combustible gas such as coal gas, water gas and semi-water gas or the mixture of the above. The method ensures the steady operation of the system, prevents the system from shutting down during overhaul and decreases the economic loss. The method also provides a safe environment in an absolutely insulated system to avoid fire or such safety misadventures.
Description
Technical field
The present invention relates to the method for gas holder long period safe and stable operation.
Background technique
Gas holder is a kind of equipment that leaves standstill that is used to store with buffer gas, belongs to movable volume basin one class.Gas holder is tight-closed, unlikely gas leakage and can equilibrium air pressure, regulate air demand.According to the encapsulating method difference of structure, gas holder is divided into two kinds of dry gasholder and wet gasholders.Wet gasholder is mainly formed (middle joint also can be called the tower joint) by seal tank, middle joint, bell jar.In seal tank, place bell jar and middle joint, bell jar and the lifting of middle joint along with the turnover of stored-gas, and utilize water seal to cut off inside and outside gas to store and buffer gas.
In the production, gas passes in and out gas holder for a long time, and is very big to the corrosivity of gas holder, occurs leak source easily.In this case, generally use the pitch leak stopping, but the non-constant of this effect, not only can not leak stopping, leak source is enlarged gradually.Perhaps when gas holder moves, get angry, be in extreme danger, easily cause security incident or equipment accidents such as fire, the normal operation that influence is produced but get angry.Perhaps, ensure its safe and stable operation, regularly carry out annual test with to equipment care and maintenance in addition in order to prevent that gas holder from breaking down.So, not only delayed production but also influenced benefit.
Summary of the invention
The method that the purpose of this invention is to provide a kind of wind chest parallel type operation that makes gas holder long period safe and stable operation and economize on the use of funds.
The object of the present invention is achieved like this: configuration Liang Tai in parallel and the gas holder more than two, and wherein one or more gas holder operation, one or more gas holder is standby.Gas holder is a wet gasholder.The pressure of gas holder is 5-9kPa.The gas of storing can also can be two kinds or more of hybrid inflammable gas wherein for inflammable gass such as coal gas, water gas, semi-water gass.
The method of wind chest parallel type operation provided by the present invention, by parallel connection configuration Liang Tai and the gas holder more than two, one or more operation, one or more is standby, guaranteed the stable operation of system, avoided the system shutdown that brings because of overhaul gas container, the economic loss of bringing when greatly reducing overhaul gas container, and created the security context of an absolute isolated system to overhaul gas container, stopped the generation of security incidents such as fire, in addition, the loss that brings because of annual test has also reached and has minimized, and has significantly reduced to produce and loss economically.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment
Working principle of the present invention is: suppose that a gas holder moves, many gas holders are standby gas holder.When this gas holder breaks down needs maintenance or stoppage in transit, in order to guarantee that synthetic ammonia continues to produce, can drain water in the import water seal in the standby gas holder this moment, this standby gas holder is come into operation, maintenance or the gas holder inlet/outlet water seal water of stopping transport are sealed, isolated with system, for maintenance.
Disposed two wet type bell-jar type gas holders 1,2 in the ammonia operation, the pressure of gas holder is 5-9kPa.U type water seal 3,4 seals the gas holder import respectively, is convenient to switch gas holder.Gas holder 1 is the operation gas holder, and gas holder 2 is standby gas holder.Gas holder 1 needs maintenance at present, and the water in the inlet/outlet U type water seal 4 of the gas holder 2 of at first draining is incorporated gas holder 2 in the system into; Add water for then gas holder 1 import water seal, semi-water gas can not be entered in the gas holder 1; Seal the outlet water seal of gas holder 1 again, make it isolated with system; Drive the antiaircraft valve in gas holder 1 top at last, use CO
2Gas or steam are replaced gas in the gas holder 1, in order to maintenance.
Can the gas holder of configuration in parallel more than at least two in actual production, wherein one or more gas holder operation, one or more gas holder is standby.
Claims (4)
1. the method for wind chest parallel type operation is characterized in that: the gas holder of configuration in parallel more than at least two, and wherein one or more gas holder operation, one or more gas holder is standby.
2. the method for wind chest parallel type operation according to claim 1, it is characterized in that: gas holder is a wet gasholder.
3. the method for wind chest parallel type operation according to claim 1, it is characterized in that: the pressure of gas holder is 5-9kPa.
4. the method for wind chest parallel type operation according to claim 1, it is characterized in that: the gas of storage can also can be two kinds or more of hybrid inflammable gas wherein for inflammable gass such as coal gas, water gas, semi-water gass.
