Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Accompanying drawings the specific embodiment of the present invention, as shown in Figure 1, butadiene turnover goods and storage at lower temperature system, comprise multiple spherical tanks, canned motorpump p, rock gas gas compressor t and valve;
Described each spherical tank comprises liquid phase stock up pipe yj, liquid phase shipment pipe yc, gas phase pipe q;
Described spherical tank is connected by liquid phase pipe yj and the liquid phase supervisor yjz that stocks up that stocks up, and liquid phase is stocked up and is responsible for yjz and is connected with the pump that harbour unloads on freighter;
Described liquid phase shipment pipe yc is connected with liquid phase shipment looped pipeline ycf by canned motorpump p, and liquid phase shipment looped pipeline ycf is connected with liquid phase shipment supervisor ycz, and liquid phase shipment supervisor ycz is connected with loading groove tank;
Liquid phase shipment looped pipeline ycf also with liquid phase stock up supervisor yjz be connected;
Described gas phase pipe q is responsible for qz by gas phase and is connected with pump, loading groove tank that harbour unloads on freighter respectively;
Described gas phase supervisor qz is access rock gas gas compressor t in parallel also;
Described rock gas gas compressor t is also connected with liquid phase shipment looped pipeline ycf.
Also comprise heat exchanger b, access heat exchanger b in parallel on liquid phase shipment looped pipeline ycf;
Corresponding valve is installed on each pipeline.
Concrete mode of operation is:
One, the butadiene operation of unloading a ship in from harbour to spherical tank:
Butadiene liquid utilizes pump on ship directly to deliver to from the harbour direction liquid phase supervisor yjz that stocks up the spherical tank needing, and opens liquid phase on this spherical tank pipe yj valve of stocking up, as the spherical tank a that stocks up, and opens va3, va4; Several spherical tanks are stocked up simultaneously, open the valve on these spherical tanks simultaneously;
If the gas pressure in spherical tank is too high, the pump on ship does not enter butadiene, opens gas phase pipe q upper valve va5, the va6 of this spherical tank, open again valve v1, v3, v19, v18 on gas phase supervisor qz, close v7, return a part of butadiene gas to ship, reduce pressure and can continue unloading.
Also can carry out step-down by rock gas gas compressor t, open spherical tank gas phase pipe q upper valve va5, va6, open valve v18, v7, v30, close v19, through rock gas gas compressor t, open v32, v29, v27, v34, v6, v17, v5, stock up and be responsible for yjz through liquid phase, the liquid phase of opening again other spherical tanks pipe yj valve of stocking up, arranges into corresponding spherical tank.
If rock gas gas compressor t outlet temperature is too high, close v34, open v24, through heat exchanger b, after heat exchange cooling, open v22, v20, v17, v5, stock up and be responsible for yjz through liquid phase, the liquid phase of opening again other spherical tanks pipe yj valve of stocking up, arranges into corresponding spherical tank, reduces pressure and can continue unloading.
Two, during butadiene storage, spherical tank cooling is processed:
Open the liquid phase shipment pipe yc valve va1, the va2 that need cooling spherical tank a, open valve v9, v10, open valve v11, v12, close v6, start canned motorpump p, open v24, through heat exchanger b, after heat exchange cooling, open v22, v20, v17, v5, va3, va4 get back in original spherical tank a, the butadiene in can the cooling spherical tank a of circulation temperature lowering is to safety temperature.Also the butadiene after cooling can be stored in to other any spherical tanks, only need open the corresponding spherical tank valve of stocking up.
Three, spherical tank carries out tank switching and tank-cleaning operation:
Tank switching: open the liquid phase shipment pipe yc valve va1, the va2 that need the spherical tank a that need to pour in down a chimney, open valve v9, v10, open valve v11, v12, v6, start canned motorpump p, open v17, v5, enters in other spherical tanks from the liquid phase supervisor yjz that stocks up.
Clear tank: the interior butadiene liquid phase of spherical tank a conductively-closed pump p installs, but in spherical tank, also has butadiene gas, open valve va5, va6 on the gas phase pipe q of spherical tank a, open the upper valve v18 of gas phase supervisor qz, throttle down v19, open v7, v31, v32, v29, start rock gas gas compressor t, open v28, v26, butadiene gas can be responsible for to qz by gas phase puts in groove tank car, thereby as far as possible the butadiene amount in spherical tank is dropped to minimumly, then replace by water-filling or nitrogen, reach tank clearly.
Four, from spherical tank to the operation of freighting of groove tank car or ship:
Car loading operation, opens liquid phase shipment pipe yc valve va1, the va2 of spherical tank a, opens valve v9, v10, opens valve v11, v12, v6, starts canned motorpump p, closes v17, opens v8, can pack in groove tank of tank car by liquid phase shipment supervisor ycz;
If groove tank internal pressure is too high, canned motorpump p can not get through, open gas phase supervisor qz valve v2, v3, v18, v19, open again valve va5, the va6 of the gas phase pipe q of spherical tank a, return a part of butadiene gas in spherical tank a from the gas phase mouth of groove tank, the pressure reducing in groove tank can continue car loading operation;
Ship-loading operation, close v8, open v17, v4, by liquid phase stock up supervisor yjz can load onto ship, if ship overpressure, canned motorpump p can not get through, open gas phase supervisor qz upper valve v1, v3, v18, v19, open valve va5, va6 on the gas phase pipe q of spherical tank a again, return a part of butadiene gas to spherical tank a in, the butadiene gas pressure in reduction cabin can continue ship-loading operation.
If the butadiene excess Temperature of shipment or car loading operation pump discharge, can open and close after corresponding valve is lowered the temperature by heat exchanger and be transported in groove tank or in cabin.
