KR20050015929A - Device for recovering liquefied petroleum gas and liquefied natural gas from a fuel tank of a waste vehicle completely, and purifying and recharging recycled fuel - Google Patents

Abstract

PURPOSE: A recovering, purifying and recharging device of high purity LPG(liquefied petroleum gas) or LNG(liquefied natural gas) is provided to prevent air pollution and the accident such as explosion or fire from discharge of residual fuel, and to reduce working hours by recovering, purifying and recharging fuel from the fuel tank of the waste vehicle. CONSTITUTION: A waste fuel recovering, purifying and recharging system for recovering, purifying and recharging liquefied petroleum gas and liquefied natural gas from the fuel tank of the waste vehicle is composed of a pressure vent(8), an LPG/LNG liquefying and recovering inlet, a low temperature gas liquefier, an expansion valve, an H-discharge port(30), a drier, a liquid pump(43), an LPG high purity purifier, a chip and metal separator, a water, dust and impurity separator, a load cell, a scale plate, an LPG high purity purifier body(70), and automatic and manual controllers.

Description

LPG / LNG Recovery High Purity Regeneration Filling Device {omitted}

The purpose of the present invention is to dispose of LPG / LNG cars, which are spread in terms of environmental preservation, in our reality that the number of vehicles owned each year is increasing in the process of developing eco-friendly fuel for the development of industrial society and the development of automobile culture. LPG / LNG waste fuel tanks, which are the fuel tanks of automobiles, are used to recover, purify, and reuse all of the remnant of 3 to 30 kg, and to prevent large explosion accidents due to the safety and unauthorized release of the junkyard.

Specially designed purifier, receiver, compressor, and filter are connected in series and parallel to exchange energy by pressure and temperature. It is an ultra low temperature method of capture injection method that concentrates recovery and purification.

In the prior art, since the LPG compressor uses a steel tube or the like to compress a large tank by a large-sized plant and a large compressor, the apparatus has to be enlarged. Existing products can only be processed at 7.5 horsepower or more.

The technical problem to be achieved by the present invention is currently being developed up to 5HP.

The first task is to invent up to 10HP in the future when needed.

LPG / LNG (liquefied natural gas) is recovered and recovered from the waste container through the first gas recovery inlet and the 13 liquid recovery inlet and refilled into a new container for reuse.
