Embodiment 1

[0050] Dissolve 200g of sodium hydroxide in 600g of water, stir and dissolve, open the feeding valve 2, and add it from the feeding port 1; put the cage containing 100g of aluminum particles with an average diameter of 1mm on the reaction table from the feeding port 1, and the reaction occurs immediately. hydrogen. The hydrogen starts to be delivered within 1 minute, and the system tends to be stable after 3 minutes. After that, the reaction of the device can automatically adjust the progress of the reaction, that is, automatically control the start and stop of the reaction. The hydrogen output rate was kept between 1 and 1.5 L / min within 130 minutes, and the reaction was terminated after 150 minutes.

[0051] When the fuel cell stops working, the gas outlet 16 is closed, the gas supply ends, and the gas pressure relief valve 3, the feed valve 2, and finally the waste residue discharge valve 11 are opened simultaneously to discharge the waste residue.

Embodiment 2

[0053] Open the pressure relief valve 3, close the slag discharge valve 11, add 70g of sodium hydroxide into 150g of water and stir to dissolve, open the feed valve 2, and add it from the feed port 1. Add the cage with 50g of aluminum pellets through feed port 1; close pressure relief valve 3 and feed valve 2 to produce hydrogen. Open the hydrogen outlet valve 16, the hydrogen reaches the pressure reducing valve 20 through the gas washing tank 18, and finally enters the electric stack 21 (design power is 50W), the hydrogen-air fuel cell generates electricity through the inverter 25 output, and supplies the water pump 27 (rated power 32W ), the last water pump 27 sucks the raw water and after PP cotton filtration, activated carbon filtration 23 and ultrafiltration membrane 25 filtration, obtain safe drinking water, and the water production rate is 2 liters / min. The continuous operation time is 8 hours, and the water production rate does not decrease significantly.

Embodiment 3

[0056] Open the pressure relief valve 3, close the slag discharge valve 11, add 70g of sodium hydroxide into 150g of water and stir to dissolve, open the feed valve 2, and add it from the feed port 1. Add the cage with 50g of aluminum pellets through feed port 1; close pressure relief valve 3 and feed valve 2 to produce hydrogen. Open the hydrogen outlet valve 16, the hydrogen reaches the pressure reducing valve 20 through the gas washing tank 18, and finally enters the electric stack 21 (design power is 50W), the hydrogen-air fuel cell generates electricity through the inverter 25 output, and supplies the water pump 27 (rated power 32W ), the last water pump 27 sucks up the raw water and filters through PP cotton, activated carbon filter 23 and reverse osmosis membrane 25 to obtain safe drinking water, and the water production rate is 0.7 liters / min. The continuous operation time is 8 hours, and the water production rate is 0.5 liters / minute.

Abstract

An emergency water purifier capable of producing hydrogen by liquid aluminum and being powered by a proton-exchange membrane fuel battery comprises a liquid-aluminum hydrogen producing system (1), a proton-exchange membrane fuel battery power generating system (2) and a membrane-method water purifying system (3). An improved self-balanced aluminum-liquid hydrogen producing device is adopted so that high-purity hydrogen can be safely and stably produced without energy consumption. The hydrogen is fed into the proton-exchange membrane fuel battery to generate power, the power is outputted from an inverter to be supplied to a water pump, so that the water pump can suck different types of surface water, sewage and the like, and the surface water, the sewage and the like are treated by an ultrafiltration membrane or a reverse osmosis membrane or the like to obtain safe drinking water. By the aid of the emergency water purifier, a virtuous circle of 'capabilities of generating power with water and producing safe drinking water with the power' is truly realized in various emergency places such as natural disasters. The emergency water purifier can be started quickly, is simple and convenient to operate, small in size and convenient to carry, is safe, stable, environment-friendly and light, and is particularly suitable for emergency such as earthquake, flood disaster and various epidemic situations, field rescue, field battles, field exploration construction.

Description

technical field [0001] The patent of the present invention relates to an emergency water purifier powered by hydrogen production from aluminum water and proton exchange membrane fuel cells, which is especially suitable for emergency rescue in natural disasters such as earthquakes. It belongs to three intersecting fields of water treatment, aluminum hydrogen production and proton exchange membrane fuel cell. technical background [0002] At present, the number of natural disasters around the world is gradually increasing, and the disaster situation is gradually aggravating, and even a variety of disasters are mixed and superimposed. For example, on March 11, 2011, a magnitude 9 earthquake occurred in Japan, simultaneously triggering multiple disasters such as tsunami and nuclear leakage. When a disaster strikes, how to save more lives and minimize the losses caused by the disaster. This is a major issue before the governments of all countries. The key way out is to provide...
