Abstract
A liquefied natural gas latent heat recycling system for liquefied natural gas ships and boats comprises a spiral gas passage which is arranged on the outer wall of a natural gas pressure-reducing valve. An outlet of the spiral gas passage is communicated with equipment needing to be cooled, and an inlet of the spiral gas passage is communicated with the outside atmosphere. The liquefied natural gas latent heat recycling system is simple in structure, low in manufacturing cost and high in utilization rate of latent heat of vaporization of liquefied natural gas, the spiral gas passage on the outer wall of the natural gas pressure-reducing valve increases air resistance, improves gas-solid heat exchanging coefficient and more efficiently utilizes the latent heat of vaporization of the liquefied natural gas, energy conservation and environment protection of a cabin are realized, leading low-temperature air into an engine room can lower temperature of the cabin, leading the low-temperature air into a storage bin can retain freshness of materials to reduce energy consumption when the cabin is provided with a refrigerator, leading the low-temperature air into the cabin in hot days can assist an air conditioner in lowering temperature, power of the air conditioner can be reduced, and energy consumption can be reduced.
Description
Technical field
The utility model relates to a kind of energy and recycles system, especially relates to a kind of recycling system of liquefied natural gas ships and light boats latent heat of vaporization energy.
Background technology
Along with day by day increasing the weight of of energy shock, the energy is variation gradually, and natural fuels becomes the primary selection that substitutes traditional energy, and progressively is applied to the every field of social life.Liquified natural gas is because the advantage of storage is widely used in various power plants.For liquified natural gas yacht driving engine, natural fuels is in being converted to the process that gaseous state enters cylinder by liquid state, because can absorbing a large amount of heat, the latent heat of vaporization make natural gas pressure-reducing valve temperature on every side greatly descend, but near the cold air for natural gas pressure-reducing valve also is not effectively utilized so far.
Chinese patent 200820230397.3 discloses a kind of liquefied natural gas vehicle air conditioning device, and it comprises radiating gill, and the medium inlet pipe of radiating gill connects the freeing pipe of liquefied natural gas bottle, and the medium of radiating gill goes out the air inlet pipe that pipe connects liquified natural gas vaporizer.This device gas-solid heat exchange coefficient is low, and liquified natural gas latent heat of vaporization capacity usage ratio is low.
The utility model content
Technical problem to be solved in the utility model is, overcomes the defects that prior art exists, and the recycling system of the high liquefied natural gas ships and light boats latent heat of vaporization energy of liquefied natural gas vaporization latent heat capacity usage ratio is provided.
The technical scheme that its technical matters that solves the utility model adopts is, the recycling system of liquefied natural gas ships and light boats latent heat of vaporization energy, comprise spiral gas passage, described spiral gas passage is located on the natural gas pressure-reducing valve outer wall, the outlet of described spiral gas passage is communicated with needing cooling equipment, and the import of described spiral gas passage is communicated with ambient atmosphere.
Further, the import of described natural gas pressure-reducing valve is communicated with the outlet of liquefied natural gas bottle, is provided with the natural fuels passage in described natural gas pressure-reducing valve, and the outlet of described natural fuels passage is communicated with the import of natural gas engine.
Further, the described cooling equipment that needs is engine bin and/or storing bin and/or ship storehouse.
Working process:
Liquified natural gas flows out through natural gas pressure-reducing valve decompression vaporization from the liquefied natural gas bottle outlet, natural fuels after vaporization enters the natural fuels passage in natural gas pressure-reducing valve, flow out through the natural fuels channel outlet, thereby supply natural gas generator, absorb the spiral gas passage import leaked-in air of amount of heat from the natural gas pressure-reducing valve outer wall that vaporization needs, make simultaneously the air themperature in the spiral gas passage of natural gas pressure-reducing valve outer wall of flowing through greatly reduce, Cryogenic air flows into through spiral gas passage outlet to be needed in the equipment of cooling.
The utility model is simple in structure, low cost of manufacture; Liquified natural gas latent heat of vaporization capacity usage ratio is high, and the spiral gas passage on the natural gas pressure-reducing valve outer wall increases air resistance, improves the coefficient of heat transfer of gas-solid, more efficiently utilizes the latent heat of vaporization energy of liquified natural gas; Make the energy-conservation and environmental protection of cabin, Cryogenic air imports in the cabin can reduce cabin temperature, and importing can be fresh-keeping to goods and materials in storing bin, reduce the energy consumption that ships and light boats carry refrigerator, but during heat, Cryogenic air is imported auxiliary air conditioner cooling in cabin, can reduce the power of air-conditioning simultaneously, reduce energy consumption.
Description of drawings
Fig. 1 is the functional-block diagram of the utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, the present embodiment comprises spiral gas passage 3, and described spiral gas passage 3 casts from natural gas pressure-reducing valve 2 outer walls, described spiral gas passage 3 outlets respectively with engine bin 7, storing bin 5 and cabin 6 are communicated with, and described spiral gas passage 3 imports are communicated with ambient atmosphere.
Described natural gas pressure-reducing valve 2 imports are communicated with liquefied natural gas bottle 1 outlet, are provided with natural fuels passage 4 in described natural gas pressure-reducing valve 2, and described natural fuels passage 4 outlets are communicated with natural gas engine 8 imports.
Working process:
liquified natural gas flows out through natural gas pressure-reducing valve 2 decompression vaporizations from liquefied natural gas bottle 1 outlet, natural fuels after vaporization enter natural fuels passage 4 in natural gas pressure-reducing valve 2, flow out through 4 outlets of natural fuels passage, thereby supply with natural gas generator 8, absorb the spiral gas passage 3 import leaked-in airs of amount of heat from natural gas pressure-reducing valve 2 outer walls that vaporization needs, make simultaneously the air themperature in the spiral gas passage 3 on natural gas pressure-reducing valve 2 outer walls of flowing through greatly reduce, Cryogenic air is through spiral gas passage 3 outlet inflow engine storehouses 7, in storing bin 5 and cabin 6.
