Liquid gas gasification method and its circulation type gasification apparatus

Abstract

The invention discloses a liquid gas gasifying method and a circular type gasifying device thereof. The method has simple process as well as energy saving and environment protection. The gasifying device has simple structure and is energy-saving and environment-friendly. The gasifying method comprises the following steps: the hot waste gas at the discharge outlet of a boiler is used for heating water through a heat exchanger, the heated water is sprayed on a gas holder and gasifies the liquid gas through heating, after that, the water is recovered and delivered to the heat exchanger through a water supply device for second heat exchange with the hot waste gas. The gasifying device comprises a heating appliance consisting of a sheet heating body and a tube type heating body, the heat exchanger arranged on the heating appliance and consisting of a heat absorption pipe coil, a spraying device connected with the outlet of the heat absorption pipe coil, a catchwater channel arranged relative to the spraying device and connected with a purifying tank, and a water pump connected between the inlet of the heat absorption pipe coil and the purifying tank.

Description

Technical field: [0001] The invention relates to a liquefied gas gasification method and a circulating gasification device thereof. Background technique: [0002] At present, the structure of the known electric hot water gasifier is composed of a cylinder with heat preservation, a serpentine pipe, an electric heater, and a gas-liquid phase connection pipe. The liquid liquefied petroleum gas enters the gasifier along the liquid phase pipe inlet, From top to bottom, it flows along the inner serpentine coil immersed in hot water, absorbs the heat transferred by the hot water outside the tube and gasifies, and the gaseous liquefied petroleum gas rises from the middle gas collection pipe, and is supplied after the gas phase tube is regulated. The residual liquid of liquefied petroleum gas is discharged through the sewage pipe at the bottom of the gas collection pipe. However, this kind of gasifier has a complex process structure, insufficient heat absorption area, and low gasific...

Problems solved by technology

[0002] At present, the structure of the known electric hot water gasifier is composed of a cylinder with heat preservation, a serpentine pipe, an electric heater, and a gas-liquid phase connection pipe. The liquid liquefied petroleum gas enters the gasifier along the liquid phase pipe inlet, From top to bottom, it flows along the inner serpentine coil immersed in hot water, absorbs the heat transferred by the hot water outside the tube and gasifies, and the gaseous liquefied petroleum gas rises from the middle gas collection pipe, and is supplied after the gas phase tube is regulated. The residual liquid of liquefied petroleum gas is discharged through the sewage pipe at the bottom of the gas collection pipe. However, this kind of gasifier has a complex process structure, insufficient heat absorption area, and low gasification capacity. When the gas supply is too large or exceeds the gasification capacity of the equipment, It is easy to cause condensation on the gas phase outlet pipe of the vaporizer, water drops or frost on the outside of the gas phase pipe, thus losing the gasification ability, and only electricity is used as the heat source power, which consumes a lot of energy. Electric heating, unsafe
