Abstract
The invention discloses a natural gas engine hot water circulating gas supply device for a ship. The device comprises a liquefied natural gas (LNG) steel cylinder, a low-temperature valve, a hot water type carburetor, a front pressure-regulating pressure gauge, a front pressure-regulating valve, a pressure regulator, a rear pressure-regulating valve, a rear pressure-regulating pressure gauge and a natural gas engine connected in series through pipelines; the hot water type carburetor is provided with a hot water inlet and a hot water outlet; and the LNG steel cylinder, the air temperature type carburetor and the natural gas engine are fixed on a clamping plate of the ship respectively. The device has the advantages of simple structure, low cost, energy conservation, safety and reliability in operation, capability of reducing carbon emission, and suitability for a power system for a Chinese inland river boat.
Description
(1) technical field
The present invention relates to natural gas engine air feeder peculiar to vessel, particularly a kind of natural gas engine hot water circuit formula air feeder peculiar to vessel.
(2) background technique
China's power system peculiar to vessel mainly is power source with diesel oil at present, diesel oil was the fuel in short supply of China in recent years, with diesel oil is the energy of power system peculiar to vessel, the economic development situation that can not adapt to China, particularly under the situation that demand increases sharply being becoming tight diesel oil supply day, will inevitably cause diesel-fuel price constantly soaring and operation cost improves constantly, what is more important can not reach the energy-saving and emission-reduction requirement that country proposes.China inland waters is wide, and interior river valley is being runed a large amount of medium and small-scale vessels, develops in this case with LNG Liquefied natural gas (LNG) to seem particularly important for the device of power source peculiar to vessel.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of natural gas engine hot water circuit formula air feeder peculiar to vessel is provided, this apparatus structure is simple, cost is low, energy saving, safe and reliable to operation and can reduce carbon emission.
Technological scheme of the present invention:
A kind of natural gas engine hot water circuit formula air feeder peculiar to vessel, comprise after pressure gauge before LNG Liquefied natural gas (LNG) steel cylinder, Subzero valve, hot-water type vaporizer, pressure regulation, pressure regulation early gate, pressure governor, pressure regulation late gate, the pressure regulation pressure gauge and natural gas engine and be connected in series by pipeline, the hot-water type vaporizer is provided with hot water inlet and hot water outlet, and LNG steel cylinder, air-heating type gasifier and natural gas engine are individually fixed on the clamping plate of boats and ships.
Working procedure of the present invention:
The intake-outlet water temperature that at first guarantees vaporizer is not less than 60 degrees centigrade, open Subzero valve, LNG (liquified natural gas) steel cylinder liquid is pressed into the hot-water type vaporizer by steel cylinder self pressure with liquified natural gas, the liquified natural gas that enters into the hot water vaporizer advanced heating, become gaseous state by liquid state, can read pipeline pressure this moment by pressure gauge before the pressure regulation, open the pressure regulation early gate, regulate pressure governor to the required pressure of natural gas engine, read by pressure gauge after the pressure regulation, open the pressure regulation late gate, natural gas in gaseous state is transported to natural gas engine.
Advantage of the present invention is: this system architecture is simple, cost is low, and energy saving, safe and reliable to operation and can reduce carbon emission is applicable to river valley power system peculiar to vessel in China.
