Abstract
The invention relates to a gas-liquid uniform-distribution heat exchange device for natural gas. The gas-liquid uniform-distribution heat exchange device comprises a heat exchanger and a gas-liquid separator. A gas-liquid uniform-distribution seal strip is arranged in the heat exchanger and evenly provided with a plurality of transversely-arranged liquid passing concave openings and vertically-arranged vent holes. The vent holes penetrate and pass all the liquid passing concave openings. Grooves are formed in the parts, in the liquid passing concave openings, of the vent holes. The upper ends and the lower ends of the vent holes are connected with a natural gas channel in the heat exchanger. The liquid passing concave openings are connected with a liquid outlet of the gas-liquid separator. A gas outlet of the gas-liquid separator is connected with a gas inlet of the natural gas channel of the heat exchanger. According to the gas-liquid uniform-distribution heat exchange device for natural gas, natural gas is divided into a gas phase and a liquid phase by the gas-liquid separator, the gas phase enters the heat exchanger for even heat exchange, and then the gas phase and the liquid phase are converged at the gas-liquid uniform-distribution seal strip and discharged out of the heat exchanger together after being evenly mixed.
Description
Technical field
The present invention relates to heat exchanger, be specifically related to a kind of natural gas gas-liquid even distribution device.
Background technology
When natural gas enters in heat exchanger and carries out heat exchange, because natural gas is gas-liquid mixed state, the flow velocity of liquid and the flow velocity of gas inconsistent, cause natural gas skewness in heat exchanger, cause heat exchanger heat exchange also uneven.
Summary of the invention
The applicant, for above shortcoming, is studied improvement, provides a kind of change natural gas gas-liquid even distribution device making natural gas gas-liquid being uniformly distributed heat exchange.
The technical solution adopted in the present invention is as follows:
The uniform heat-exchanger rig of a kind of natural gas gas-liquid, comprise heat exchanger and gas-liquid separator, the uniform strip of paper used for sealing of gas-liquid is set in described heat exchanger, the uniform strip of paper used for sealing of described gas-liquid evenly offers the logical liquid recess of some lateral arrangement and the vertical passage arranged, described passage runs through by all logical liquid recesses, and the part of passage in logical liquid recess forms groove, the two ends up and down of described passage all with the natural gas expanding channels in heat exchanger, described logical liquid recess is connected with the liquid outlet of gas-liquid separator, the gas outlet of described gas-liquid separator is connected with the air inlet of the natural gas passage of heat exchanger.
Further improvement as technique scheme:
Described logical liquid recess is U-shaped recess.
Described passage is circular port, and the groove that described passage is positioned at the formation of logical liquid recess is circular groove.
Beneficial effect of the present invention is as follows: the uniform heat-exchanger rig of described natural gas gas-liquid, first by gas-liquid separator, natural gas is divided into gas phase and liquid phase, gas phase enters uniform heat exchange in heat exchanger by the gas outlet of gas-liquid separator and the air inlet of heat exchanger natural gas passage, and enter in the passage of the uniform strip of paper used for sealing of gas-liquid, liquid phase enters in the logical liquid recess of the uniform strip of paper used for sealing of gas-liquid by gas-liquid separator liquid outlet, the gas phase of described different in flow rate is contacting at the uniform strip of paper used for sealing of gas-liquid with liquid phase, gas-liquid can be realized be uniformly distributed, and discharge heat exchanger together.
