Large LNG gasification and two-way pressure regulating integrated prying device

Abstract

The invention discloses a large LNG gasification and two-way pressure regulating integrated prying device. The large LNG gasification and two-way pressure regulating integrated prying device comprises a gasifier A, a gasifier B, a water bath type electric heating device, a pressure regulating device A, a pressure regulating device B, a safely diffusing device A, a safely diffusing device B, a metering device, an odorizing device, a pressure regulating and metering box and a base platform; the gasifier A, the pressure regulating device A, the safely diffusing device A, the metering device and the odorizing device are connected in series through pipes in sequence and are welded to the base platform correspondingly; and the gasifier B is connected to the gasifier A in parallel, the pipe between the gasifier A and the pressure regulating device A is connected with the water bath type electric heating device in parallel, and the pressure regulating device A and the safely diffusing device A are connected with the pressure regulating device B and the safely diffusing device B in parallel. The large LNG gasification and two-way pressure regulating integrated prying device is high in integrated degree and high in reliability, investment is saved, the construction cycle is shortened, operation is simple and convenient, and gas supply efficiency is high.

Description

technical field [0001] The invention relates to the field of heat supply, energy saving and environmental protection equipment, in particular to a large-scale LNG gasification two-way pressure regulation integrated skid. Background technique [0002] With the increasing development of the world economy and science and technology, and the increasing awareness of human environmental protection, natural gas, as a clean energy source and an important chemical industry raw material, has been more widely used. At present, natural gas equipment has the following deficiencies: 1. Customers use natural gas for a long period; 2. The gasifier, pressure regulating and metering part, and odorizing device are arranged separately, resulting in a large area for the equipment, inconvenient transportation, cumbersome installation, and difficult project construction. The cycle is longer; 3. The type of weld used in welding, such as butt weld, increases the difficulty of welding operation, insp...

Problems solved by technology

At present, natural gas equipment has the following deficiencies: 1. Customers use natural gas for a long period; 2. The gasifier, pressure regulating and metering part, and odorizing device are arranged separately, resulting in a large area for the equipment, inconvenient transportation, cumbersome installation, and difficult project construction. The cycle is longer; 3. The type of weld used in welding, such as butt weld, increases the difficulty of welding operation, inspection cost and operation risk; 4. The pressure regulating and measuring part is exposed to the atmospheric environment, causing pressure regulating valve and flowmeter The service life of main pipe fittings and components is short, and the risk of safe and reliable operation increases

5. If part of the gas supply line is damaged, the whole line will not work normally, affecting the use of natural gas by customers
