Abstract
The utility model relates to an automatic nitrogen pressurizing system of a large stainless steel oil tanker for chemicals finished products. The system comprises a nitrogen generating chamber, wherein the nitrogen generating chamber is arranged at the tail end of the tanker body of the oil tanker, and control equipment, a regulating valve and a pressure sensor are sequentially connected to the nitrogen generating chamber in the direction toward the tanker head of the oil tanker by a gas delivering pipeline; the control equipment is connected with the nitrogen generating chamber by a control cable and is connected with the pressure sensor by a communication cable; and the regulating valve is a self-actuated pressure regulating valve. The utility model has the benefits that the system has a simple structure and high reliability and is convenient to operate; inert gas for protecting liquid goods of the large stainless steel oil tanker for the chemicals/ finished products can be monitored in real time, the pressure of the inert gas is automatically regulated, the work intensity of workers is largely reduced, and safety accidents caused by manual misoperation when the gas pressure of a liquid goods compartment is regulated by the workers are effectively prevented.
Description
Technical field
The utility model relates to a kind of nitrogen Self-pressurizing agri system of large-size stainless steel chemical oil product carrier.
Background technology
Development along with chemical frbre industry, especially the rise of petro chemical industry, the transportation volume of raw material that it is required and products thereof increases day by day, such as the early thirties in last century, the projection of Japan's rayon industry, need to consume a large amount of sodium hydroxide, originally supplied the client in the solid transportation mode, allow again the client according to the needs of oneself solution that solid caustic soda is made into variable concentrations be used, from safety and work efficiency aspect, this method can not adapt to, for the amount transport liquid caustic soda, the Liquid Chemicals in Bulk ship that large transport liquid caustic soda product early occurred in the world, development through more than 70 years, Chemical/Product Oil Tanker has been gone through the change in four epoch, be at present for the 4th stage in generation, its principal feature is: tonnage is larger, separate closeer, cargo hold 70% has adopted high-strength stainless steel material, be provided with control, heating, ventilative, detect, alarm and inert gas system have alerting ability and better running ability.
This large-size stainless steel Chemical/Product Oil Tanker liquid goods in transportation, in order to make liquid goods in transportation, the flammable degree of fire gases out of reach of cargo tank; Simultaneously; keep cargo tank can keep barotropic state; general corrosion-resistant steel chemistry product/oil product carrier adopts unreactable gas that cargo tank is protected; reached the flammable degree of gas out of reach in the cargo tank; but; owing to will keep at any time the unreactable gas in the cargo tank to be in barotropic state; just need the crewman often the pressure of cargo tank to be checked; and by the manual valve that opens and closes; carry out the gaseous tension of cargo tank and regulate, working strength is large, and the ill effect that exists human error to cause; so, be badly in need of a kind of can automatically the monitoring and the automatically improvement of regulator solution cargo hold gaseous tension.
The utility model content
The purpose of this utility model provides a kind of nitrogen Self-pressurizing agri system of large-size stainless steel chemical oil product carrier, can carry out cargo tank gaseous tension Real-Time Monitoring, automatically regulator solution cargo hold pressure has solved that present need are manually regulated the gaseous tension of cargo tank and the potential safety hazard and the large problem of working strength that exist.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of nitrogen Self-pressurizing agri system of large-size stainless steel chemical oil product carrier, comprise the nitrogen generation chamber, described nitrogen generation chamber is positioned at the hull tail end of described oil carrier, and described nitrogen generation chamber is connected with control convenience, control cock and pressure sensor in the fore direction towards described oil carrier in turn by air shooter; Described nitrogen generation chamber is connected with control convenience by control cables, and described control convenience is by communication cable Bonding pressure sensor.
Preferably, described control cock is self-contained pressure regulator.
The beneficial effects of the utility model are: this system architecture is simple, and is easy to operate, and reliability is high; Realized large-size stainless steel Chemical/Product Oil Tanker liquid goods protection unreactable gas Real-Time Monitoring and automatic pressure are regulated; greatly reduce manual working intensity, effectively prevented artificial generation because of safety misadventure that the human operational error the causes when gaseous tension of cargo tank is regulated.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the nitrogen Self-pressurizing agri system architecture schematic diagram of the described a kind of large-size stainless steel chemical oil product carrier of the utility model embodiment.
Among the figure:
1, nitrogen generation chamber; 2, control convenience; 3, control cock; 4, pressure sensor; 5, air shooter; 6, control cables; 7, communication cable.
The specific embodiment
As shown in Figure 1, the nitrogen Self-pressurizing agri system of the described a kind of large-size stainless steel chemical oil product carrier of the utility model embodiment, comprise nitrogen generation chamber 1, described nitrogen generation chamber 1 is positioned at the hull tail end of described oil carrier, and nitrogen generation chamber 1 is connected with control convenience 2, control cock 3 and pressure sensor 4 in the fore direction towards described oil carrier in turn by air shooter 5; Nitrogen generation chamber 1 is connected with control convenience 2 by control cables 6; Control convenience 2 is by communication cable 7 Bonding pressure sensors 4; Control cock 3 is self-contained pressure regulator.
During implementation, nitrogen generation chamber 1 is by air shooter 5, process self-contained pressure regulator 3 and pressure sensor 4 are to the cargo tank supplying nitrogen, pressure sensor 4 is sent to control convenience 2 with the cargo tank force value of sensing by communication cable 7 at any time, and control convenience 2 judges whether cargo tank pressure is up to standard.After up to standard, control convenience 2 is closed nitrogen generation chamber 1 by control cables 6, stop to the cargo tank supplying nitrogen, simultaneously, self-contained pressure regulator 3 autoshutdowns.
When control convenience 2 receives cargo tank force value that pressure sensor 4 senses and is lower than standard, control convenience 2 is opened nitrogen generation chamber 1 by control cables 6, pressurize to cargo tank by air shooter 5, thereby guarantee that the cargo tank inert gas pressure remains on controllable state at any time.
The utility model is not limited to above-mentioned preferred forms; can not limit to the utility model with this; other various forms of products that anyone draws under enlightenment of the present utility model; no matter do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
