Embodiment Construction

[0059] Next, the present invention will be described for a liquid storage tank of urea water used as an aqueous solution of a reducing agent for purifying exhaust gas of a diesel engine and an illustrated embodiment of the supply device. In FIGS. 1 to 8, reference numeral 1 denotes a synthetic resin. A transparent or semi-transparent liquid storage tank made of aluminum alloy is in the shape of a basic cuboid that can hold about 1000 liters of urea water, and on its peripheral surface, a plurality of concave parts or concave ribs 2 for rigidity enhancement are formed.

[0060] The liquid storage tank 1 is placed on, for example, a platform 3 for transport by a forklift, and it is stably installed in a suitable place such as a fuel supply base, a truck station, or a factory at ordinary times.

[0061] The numeral 4 in the figure represents the protective net installed around the above-mentioned tank 1, which is constructed by assembling a protective frame 5 vertically and horizo...

Abstract

The present invention provides one kind of liquid storing tank and one kind of liquid feeding device used, say, in supplying water solution of reductant for purifying exhausted gas from diesel engine and in supplying great amount of water solution from a tank car. The liquid storing tank has a detachable cover with a liquid feeding port and an air exhaust pipe.

Description

technical field [0001] The present invention relates to a liquid storage tank and a liquid supply device, which are suitable, for example, when supplying an aqueous solution of a reducing agent for purifying exhaust gas of a diesel engine, for example, a large amount of aqueous solution can be quickly and safely supplied from a tank truck, etc. A small amount of aqueous solution can be easily supplied by manpower, and it can be produced easily and at low cost with a simple scheme. Background technique [0002] The reduction mechanism of NOx contained in the exhaust gas of a diesel engine includes a type in which a NOx reduction catalyst constituting an exhaust gas purification device is provided on a diesel vehicle, and a predetermined reducing agent is added to the NOx reduction catalyst to make the NOx reduction catalyst The reducing agent performs a reduction reaction with NOx in the exhaust gas to reduce the exhaust concentration of NOx. [0003] Among them, the above-m...
