Embodiment Construction

[0060] Next, the present invention will be described for a liquid storage tank of urea water as an aqueous solution of a reducing agent for purifying exhaust gas of a diesel engine and an illustrated embodiment of the supply device. Figure 1 to Figure 8 Among them, reference numeral 1 denotes a transparent or translucent liquid storage tank made of synthetic resin, which is in the shape of a substantially rectangular parallelepiped capable of holding about 1,000 liters of urea water, and a plurality of concave parts or concave ribs 2 for rigidity enhancement are formed on its peripheral surface .

[0061] 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.

[0062] The numeral 4 in the figure represents the protective net installed around the above-mentioned tank 1, which is constructed by assembling a protectiv...

Abstract

The invention provides a liquid supply device which is suitable for supplying a reducing agent aqueous solution for purifying gases exhausted by a diesel engine, rapidly and safely supplying a great quantity of aqueous solutions from a tank car, and the like and simply and conveniently supplying a small quantity of aqueous solutions through manpower; in addition, the liquid supply device can be easily manufactured with low cost through a simple scheme. The liquid supply device comprises a liquid storage tank (1) which can be detachably arranged on a tank cover (9); the tank cover (9) is arranged on a liquid supply port (7) on the outer circumference in an opened-closed way; one end part of a pipe joint (11) is arranged on the tank cover (9); the other end part of the pipe joint protrudes towards the exterior of the tank cover (9); an air exhaust pipe (25) is arranged on the pipe joint (11); and one end of the air exhaust pipe (25) is arranged at the inner side of the tank cover (9) and the other end of the air exhaust pipe (25) is arranged at the outer side of the tank cover (9).

Description

[0001] The present invention is a divisional application of the No. 200610083749.2 invention patent application filed on June 1, 2006 with the title of "liquid storage tank and liquid supply device". technical field [0002] 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 [0003] 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 reducti...
