Description

A kind of equipment of realizing the skid of vaporizing station manufacturing equipment collective

Technical field

The utility model relates to LNG vaporizing station technical field, relates in particular to a kind of equipment of realizing the skid of vaporizing station manufacturing equipment collective.

Background technique

LNG is bringing into play more and more important effect in the city gas evolution at home, the design of LNG vaporizing station must strictly observe existing relevant specification of country, total figure is arranged on safe and reasonable ground, the temperature of serious control pipeline and equipment, pressure parameter, and the various hidden danger of automatic control that should be reasonable in design, safe, electric, fire fighting device, elimination LNG make it bring into play larger effect in social development.

LNG is transported to vaporizing station by tank car, utilize the LNG pressurized machine of unloading that the tank car internal pressure is increased, LNG in the tank car delivered in the LNG low-temperature storage tank store, when effluxing from the LNG storage tank, pass through first the white pressurization system of storage tank, pressure of storage tank is raise, then open storage tank liquid-phase outlet valve, after by pressure difference the LNG in the storage tank being delivered to vaporizer, through pressure regulation, metering, add the operation such as smelly and send into municipal gas ductwork, when outdoor environment temperature lower, when the natural temperature of air-heating type gasifier outlet is lower than 5 ℃, need at air-heating type gasifier outlet series connection water-bath type heater the rock gas after the gasification to be heated; But a series of unfavorable factors such as existing each equipment of LNG vaporizing station machine is installed separately, in the installation process, exists installation period long at the scene, and equipment Foundations are many, and on-the-spot material structure is loaded down with trivial details, and complexity, not quick detachable movement are installed.

Summary of the invention

The purpose of this utility model provides a kind of equipment of realizing the skid of vaporizing station manufacturing equipment collective, and it is simple in structure, dismantles simple and easy, conveniently moving, mounting material is few, has accelerated installation period, reduce the workload of construction site, adjusted flow process, realized the overall skid-mounted of field apparatus.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is comprised of chassis 1, the first main vaporizer 2, the second main vaporizer 3, BOG heater 4, EAG heater 5, the supercharging vaporizer 6 of unloading, pressure regulation metering device for adding odor 7, storage tank supercharging vaporizer 8; The middle part on chassis 1 is provided with the first main vaporizer 2 and the second main vaporizer 3, one side of the first main vaporizer 2 is provided with BOG heater 4 and EAG heater 5, one side of the second main vaporizer 3 is provided with pressure regulation metering device for adding odor 7, and the two ends, the left and right sides on chassis 1 are respectively arranged with storage tank supercharging vaporizer 8 and the supercharging vaporizer 6 of unloading.

Be provided with liquid phase, gas phase and the supercharging liquid phase mouth of mouthful corresponding tank car of unloading on the skid mounted equipment of the present utility model, feed liquor, fluid, gas phase and the diffusion mouth of the corresponding storage tank of storage tank mouth, so pipeline and electric meter the sled in the installation, spare interface, on-the-spot directly abutting joint gets final product, and on-the-spot mounting material is few, simple and convenient, can dismantle at any time, greatly save the duration, for the vaporizing station construction creates favorable conditions.

Working principle of the present utility model: the LNG in the tank car at the unloading deck place by the 6 pairs of container storage tank superchargings of supercharging vaporizer of unloading, utilize pressure reduction that LNG is delivered to low temperature LNG storage tank stores, under the operating conditions, pressurized machine is pressurized to low temperature LNG after the 0.5MPa supercharging with the LNG in the storage tank, enter main air-heating type gasifier, with be converted into gaseous state NG and the temperature that raises behind the air heat-exchange, outlet temperature is lower 10 ℃ than ambient temperature, pressure is at 0.5MPa, when the natural gas temperature of air-heating type gasifier outlet does not reach more than 5 ℃, heat up by the electric heating type heater, finally by pressure regulation, metering, add and send into gas pipeline after smelly, for gas equipment.

The utility model is simple in structure, dismantle simple and easy, conveniently moving, mounting material is few, has accelerated installation period, has reduced the workload of construction site, has adjusted flow process, has realized the overall skid-mounted of field apparatus.
