Description
Technical field
The utility model relates to natural gas liquids receiving station, particularly relates to a kind of natural gas liquids receiving station with inhibition system of killing livestock.
Background technology
The major function of natural gas liquids (LNG) receiving station is the LNG that receives, stores and gasify, and by pipe network to downstream user air feed.Current gasification LNG mainly adopts open-frame type gasifier, and in open-frame type gasifier, LNG is by heating of seawater, gasification for Sweet natural gas, carries downstream user after metering, and therefore, sea water system is one of system very important in receiving station.In actual motion, there are marine organisms and be attached to risk in sea water pipe system and equipment in a large number.For tackling above-mentioned risk, receiving station generally adopts the mode of electrolytic seawater to produce chlorine bleach liquor, and injects sea water system with finite concentration.
Large quantity research shows that chlorine residue has certain toxic action to marine organisms, and some may dead or growths that stop growing to the biology of chlorine residue sensitivity, and biomass will have certain minimizing, the species number of biology also by due to sensitivity kind disappearance and walk quickly and keep away and reduce.Although each LNG receiving station is when designing this chlorination system, all have strict demand (secure threshold is 0.2mg/l) to the contents of residual chlorine in seawater row sea, generally speaking range of influence is limited to marine site for contents of residual chlorine, still affects larger on seawater discharge mouth surrounding waters.
Utility model content
Technical problem to be solved in the utility model be overcome prior art above-mentioned deficiency and provide a kind of natural gas liquids receiving station to kill livestock inhibition system, environmentally friendly inhibiter of killing livestock can be injected the seawater intake of receiving station by this system, injection process is simple to operate, level of automation is high, system device cost is low, and can avoid destroying ecology.
The technical scheme in the invention for solving the above technical problem is: natural gas liquids receiving station kills livestock inhibition system, comprise head tank, suction pipeline, grug feeding jar, feed-stock pipeline, intake, inhibiter stoste of killing livestock is stored in head tank, suction pipeline connects head tank and grug feeding jar, feed-stock pipeline connects grug feeding jar and intake, suction pipeline arranges charging absorption pump, feed-stock pipeline arranges volume pump.
On the suction pipeline optimized, the suction pipeline of charging absorption pump front end also arranges gate valve, strainer, and rear end arranges vacuum breaker, gate valve.
On the feed-stock pipeline optimized, the feed-stock pipeline of volume pump front end arranges gate valve, and rear end arranges vacuum breaker, gate valve.
Suction pipeline, the feed-stock pipeline of further optimization all have multichannel arranged side by side.
The charging absorption pump of further optimization and the motor of volume pump are all electrically connected with Motor Control Center.
Compared with prior art, the utility model has the advantage of: inhibition system of 1, killing livestock replaces traditional seawater electrolysis device, chlorination equipment, in slave unit, technique, implementation is very easy, can storage condition friendly to kill livestock inhibiter in head tank, by charging absorption pump, volume pump etc., inhibiter of killing livestock input grug feeding jar, and be finally transported to receiving station's seawater intake, inhibiter of killing livestock enters in the watering equipment of receiving station, can effectively kill the biology in seawater and slow down the corrosion of seawater to equipment.2, suction pipeline, feed-stock pipeline arrange gate valve, strainer, vacuum breaker, and multichannel pipeline is set, the practicality of enhanced system, multiple filling can be realized and to kill livestock the technique of inhibiter.3, the motor of charging absorption pump, volume pump is electrically connected with Motor Control Center, can realize Automated condtrol.
Accompanying drawing explanation
Fig. 1 is the structural representation of figure the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment, the utility model is further illustrated.
LNG receiving station kills livestock inhibition system as shown in Figure 1, and this system comprises environmentally friendly inhibiter head tank 1 of killing livestock, suction pipeline 2, grug feeding jar 3, feed-stock pipeline 4, receiving station's seawater intake 5.
Head tank 1 is three or more, and in head tank 1, storage condition friendly is killed livestock the stoste of inhibiter.Suction pipeline 2 is separate two-way, all connect each head tank 1 and grug feeding jar 3, for killing livestock, inhibiter stoste is delivered to grug feeding jar 3, suction pipeline 2 comprises the gate valve 21, strainer 22, charging absorption pump 23, vacuum breaker 24 and the gate valve 25 that are connected by pipeline successively, after gate valve and charging absorption pump 23 are opened, inhibiter stoste of killing livestock can be delivered to grug feeding jar 3, the impurity in its middle filtrator 22 filtering stoste, vacuum breaker 24 prevents stoste from flowing backwards.
For controlling the flow velocity of stoste and the keying of charging absorption pump 23, the motor of charging absorption pump 23 is electrically connected with Motor Control Center 26, operator controls the motor of charging absorption pump 23 by Motor Control Center 26, Motor Control Center 26 can also be connected with intelligent equipment (such as programmable logic controller), realize Automated condtrol, according to system requirements, intelligentized absorption stoste.
Grug feeding jar 3 is for mixing, storing inhibiter of killing livestock, and if desired, grug feeding jar 3 also can arrange water injection pipe, agitator etc., dilutes inhibiter of killing livestock.Grug feeding jar 3 is connected by feed-stock pipeline 4 with the intake 5 of receiving station.Feed-stock pipeline 4 is separate two-way, every road feed-stock pipeline 4 comprises the gate valve 41, volume pump 42, vacuum breaker 43, the gate valve 44 that are connected by pipeline successively, after volume pump 42 and gate valve are opened, not only the inhibiter of killing livestock in grug feeding jar 3 can be delivered to intake 5, and volume pump 42 also can detect the flow of this road feed-stock pipeline, accurately to control the inhibiter dose of killing livestock being delivered to intake 5, avoid the equipment such as dose excessive harm receiving station gasifier.
