Example Embodiment

[0032] The core of the present invention is to provide a urea tank, which can solve the problem of small storage capacity and low-temperature condensation and fouling of the connecting pipe due to the use of liquid automotive urea.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Please refer to figure 1 , figure 2 with image 3 , figure 1 Is a front view of a urea tank provided by an embodiment of the present invention; figure 2 Is a...

Abstract

The invention discloses a urea tank which comprises a urea feeding port and ammonia gas outlet main body unit, a heating device used for heating urea, a controller used for judging whether the main body unit works or not and a support used for being connected with an automobile. The urea tank is connected with the automobile through the support. In operation, solid urea is fed into the main body unit through the urea feeding port. When the controller detects that nitric oxides are included in automobile exhaust, the controller controls the main body unit to start to work, namely, the solid urea in the main body unit is heated through the heating device to generate ammonia gas and the ammonia gas is discharged through an ammonia gas outlet. According to the solid urea adopted, freeze is avoided at low temperature, storage and carrying are convenient. Compared with liquid urea in the prior art, storage volume in the urea tank is large. Further, the solid urea is converted from a solid state to a gas stage directly in operation so that a connecting pipe is prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of SCR, in particular to a urea tank. Background technique [0002] Since the environmental protection departments of various countries proposed to further reduce the nitrogen oxide pollutants emitted by diesel engines (commonly known as the Euro IV standard in China), engine manufacturers began to use SCR technology (selective catalytic reduction technology) to meet the requirements of the environmental protection department. Diesel engine exhaust treatment fluid (commonly known as automotive urea in China) is a consumable that must be used in SCR technology. The SCR system includes a urea tank (loaded with automotive urea) and a catalytic reaction tank. Its working principle is: when nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays out automotive urea, and the automotive urea and nitrogen oxides are in a catalytic reaction. Oxidation-reduction reactions occur in the tank t...
