Process and device for recovering and recycling protective gas of bell-type bright annealing furnace

The invention relates to a process and a device for recovering and recycling protective gas of a bell-type bright annealing furnace. The process comprises the following steps of: performing cooling and condensation of oil and gas in refluxing protective gas of a bell-type bright annealing furnace group; allowing the cooled and condensed protective gas to enter a water separator to remove most of water and oil; allowing the cooled protective gas from which the oil and the gas are removed to enter a preceding stage buffer tank; after the protective gas is buffered by the preceding stage buffer tank, pressurizing by using a roots blower; allowing the pressurized protective gas to enter an oil absorption device to remove oil and enter a deaerator to remove oxygen; reacting in the deaerator to generate water and discharge heat; cooling the protective gas by using a cooler and removing water from the protective gas by using a condenser; allowing the cooled and dehydrated protective gas to enter the water separator to separate water; allowing the protective gas to enter an absorption regeneration drying device for removing water and impurities deeply; and performing decompression and voltage stabilization on the purified gas by using a post-stage buffering tank and then supplying the purified gas to the bell-type bright annealing furnace group. Through the process and the device, the refluxing protective gas of the bell-type bright annealing furnace group is recovered and purified and enters the annealing furnace to be recycled as the protective gas again.

Full-vacuum horizontal liquefied natural gas (LNG) submerged pump pool

The invention discloses a full-vacuum horizontal liquefied natural gas (LNG) submerged pump pool. The full-vacuum horizontal LNG submerged pump pool comprises a pump pool body, a submerged pump pool and a support. A liquid outlet device which is arranged on the inner side of a pump pool cap is in a structure of high vacuum and heat insulation and an outer casing tube which is arranged on the outer side of the pump poop cap is fixedly connected with a vacuumized joint. The vacuumized joint is communicated with the liquid outlet device and the structure of high vacuum and heat insulation of the full-vacuum horizontal LNG submerged pump pool is formed by the vacuumized joint and a high-vacuum and heat-insulated interlayer between an outer cylinder and inner cylinder of the full-vacuum horizontal LNG submerged pump pool. According to this arrangement, all ways of heat leakage, such as convention, conduction and radiation can be eradicated so that good cold-insulated effect can be ensured. The rate of evaporation per day of LNG in the full-vacuum horizontal LNG submerged pump pool can be reduced by 21.5% to 31.5% compared with the vertical submerged pump pool in the prior art. The full-vacuum horizontal LNG submerged pump pool can be used for filling vehicles or transporting vehicle-mounted LNG, so as to greatly improve the economic benefit of LNG filling stations, LNG transportation and filling vehicles.

Novel vehicle-mounted natural gas supply system and stable gas supply method thereof

The invention discloses a novel vehicle-mounted natural gas supply system and a stable gas supply method of the novel vehicle-mounted natural gas supply system. The novel vehicle-mounted natural gas supply system comprises an LNG storage tank, a gasification device, a liquid outlet pipe connected between the LNG storage tank and the gasification device, an LNG pump used for extracting liquefied natural gas from the LNG storage tank and a gas pressure driven device driving the LNG pump to work. The LNG pump is arranged on the liquid outlet pipe. The gas pressure driven device is arranged on a pipeline on the downstream of the gasification device and driven through gas pressure of natural gas flowing through the pipeline and connected with the LNG pump through a driving pipeline. The gas pressure driven device of the system is driven through gas pressure of the gasified natural gas in the gasification device to work and drive the LNG pump to extract the liquefied natural gas from the LNG tank, the natural gas flows through the liquid outlet pipe to the gasification device, and therefore the passive circulatory system is formed. According to the system, gas fuel can be stably supplied to an engine, a self-pressurization system is omitted, evacuation loss of natural gas is reduced, and resource waste is avoided.

Device for delivering fuel

Devices for delivering fuel are already known, comprising a suction jet pump that is arranged in a storage crucible and has a nozzle and a mixer duct provided downstream of the nozzle and arranged perpendicular to the bottom of the storage crucible, wherein at the outlet of the mixer duct an impingement means is arranged, against which the jet of the nozzle impinges in the substantially unfilled mixer duct, and in doing so is at least partially returned into the mixer duct. It has been found that despite the impingement means the propulsive jet tends to eject the liquid column present in the mixer duct. As soon as the liquid level in the storage crucible has decreased below the outlet of the mixer duct, no more fuel can replenish from above into the mixer duct so that the mixer duct may be unfilled after switching off the suction jet pump. Upon restarting the suction jet pump, an unsatisfying high delay until suction of the suction jet pump occurs, because the volume of the propulsive jet must first fill the mixer duct in order to create a vacuum and suction power. Using the device according to the invention, a pushing out of the liquid column of the mixer duct by the propulsive jet of the suction jet pump is avoided. Thus the lead time of the suction jet pump is approximately equal in all operating states. According to the invention, an additional volume (25) is formed at the outlet of the mixer duct (16) by an off-set widening (26) of the mixer duct (16).
