Abstract

A device for location in a liquid fuel tank to absorb water therein comprises a permeable bag filled with concentrated, super absorbent starch and weighted with silica sand. The bag fabric is treated with starch solution to repel the fuel and allow water to enter. The bag is connected to the tank by a line which discharges static electricity and enables the bag to be withdrawn when saturated.

Description

A MOISTURE ABSORBING DEVICE The present invention relates to a moisture absorbing device, especially, but not exclusively, for use in diesel engine fuel and fuel storage tanks.
Diesel fuel, whether stored above or below ground attracts moisture through condensation caused by the rise and fall in ambient temperature. Moisture is also introduced into storage tanks whenever these are refilled, Diesel operated machinery, vehicle and equipment produce water during combustion of diesel fuel. By design diesel engines are supplied with fuel under pressure so as to enable the fuel injection system to operate. As a consequence, excess fuel at the point of injection has to be returned to the fuel tank.This returned excess fuel, which has been previously heated in the engine, causes water in the air space above the diesel fuel in the fuel tank to condense and form a layer of later below the diesel fuel. This water causes corrosion of the fuel tank and of the fuel supply lines. It also inhibits efficient operation of the engine if it enters the fuel injection system.
It is an object of the present invention to provide a moisture absorbing device #:bich can be placed in a diesel engine fuel or fuel storage tank to remove water therefrom.
According to the present invention there is provided a later absorbing device comprising a water permeable bag filled with a concentrated, super absorbent starch and means for weighting the bag.
The concentrated super absorbent starch may be potato, based, rice based or wheat based.
Preferably, the bag is weighted with silica sand.
This ensures that the bag drops to the bottom of a tank, here any water in the tank will form a layer below the diesel fuel.
Preferably, the bag is treated with a diluted solution of super absorbent starch of the same type as is used to fill the bag. This treatment repels hydrocarbons and prevents them from entering the bag.
Preferably, the bag is comprised of rip stop nylon.
Preferably, an earthing lead is provided from the bag which is intended, in use, to be connected to the body of the tank and ensures that any static charges which might develop on the moisture absorbing device are conducted a!ay to earth. Inhere inflammable fuels are present it is important to ensure that stray static charges do not develop which might cause a spark sufficient to ignite the fuel.
A moisture absorbing device embodying the present invention will now be described, by way of example.
The water absorbing device comprises a nylon bag which is treated with a diluted solution of potato based super absorbent starch and dried. For added strength the nylon bag may be comprised of "rip stop" nylon sheeting and the seams of the bag may be French stitched.
Mle bag is filled with a concentrated mixture of potato based super absorbent starch and silica sand, and closed with French stitching. A brass eyelet is provided in the bag to which is attached a retrievable polypropelene line, interwoven throughout its length with conductive wires. A crocodile clip is attached to the free end of the line.
In use, the bag is lowered into a tank of diesel fuel and under the weight of the silica sand drops to the bottom of the tank where any water-present in the tank will have accumulated as a dense layer below the less dense diesel fuel. The crocodile clip on the end of the conductive line is secured to the body of the tank and provides a means of retrieving the bag from the tank and an earth line. In this latterrespect, it will be appreciated that in the presence of inflammable fuels every care must be taken to prevent the build up of static charges çhich might form a spark discharge and ignite the fuel.
The nylon bag is permeable to both water and diesel fuel, but the coating of potato based super absorbent starch repels all hydrocarbon fuels and allows only water to enter the bag. Within the bag water is absorbed by the concentrated mixture of potato based super absorbent starch and prevented from returning into the tank. This material has been found to be especially effective at absorbing water and can absorb many times its olfn weight.
After the water absorbing device has been in the tank for a certain length of time its water absorbing properties will have diminished to a point where absorption is minimal.
The device is then simply removed and replaced.
