Problems solved by technology

[0004] As one of the important components of the SCR urea injection system, the urea tank is currently made of plastic products, which are realized by injection molding or blow molding. Its advantages are light weight and easy to meet the installation and integration of the scr system, but it also has very The obvious disadvantage is that it is easy to age when the ambient temperature is high, and it is easy to become brittle or even cracked when the temperature is low in winter

Embodiment Construction

[0020] Referring to the accompanying drawings, the structure of a specific embodiment of the present invention includes a urea tank body 1 connected to a urea pump. The urea tank body 1 is a columnar tank with a smooth outer circumference made of stainless steel with a thickness below 1mm. The urea tank body 1 There are urea inlets and outlets on the top, and several groups of sensor mounting seats 6 are installed on the arc surface of the top of the urea tank body 1 to install various sensors for monitoring the operation status of the scr system; on the inner wall of the urea tank body 1 A strip-shaped reinforcing rib 2 distributed along the vertical direction is provided, and the strip-shaped reinforcing rib 2 extends upward and downward along the inner wall of the urea tank body 1 to the top and bottom of the urea tank body 1 respectively, and the strip-shaped reinforcing rib 2 The width of both ends of the rib 2 is half of the width of its middle point, and its width gradua...

Abstract

The invention discloses an SCR catalysis muffling system urea tank with portability and durability. The urea tank structurally comprises a urea tank body connected with a urea pump in a urea jetting system. The urea tank body is a columnar tank made of stainless steel, and the periphery of the columnar tank is smooth. Strip-shaped reinforcing ribs distributed in the vertical direction are arranged on the inner side wall of the urea tank body. Annular reinforcing ribs distributed in the horizontal direction are arranged on the outer side wall of the urea tank body. At least one set of annular reinforcing ribs extend and expand outwards to form installation wings. The installation rings are provided with threaded holes so that the urea tank body can be fixedly installed in an SCR catalysis muffling system. The stainless steel material is adopted on the premise that the dead weight is not increased and the durability and stability of the urea tank are improved.

Description

technical field [0001] The invention relates to the vehicle tail gas treatment technology, especially the SCR catalytic muffler system technology for heavy-duty diesel vehicles. Background technique [0002] According to the latest national standard requirements for maintaining treatment, a series of treatment must be performed on the exhaust of heavy-duty diesel vehicles in order to meet emission requirements. As China's emission control regulations become more and more stringent, as well as the performance and oil quality of domestic diesel engines, it is not enough to rely solely on in-engine purification measures. Therefore, it is necessary to adopt an off-machine after-treatment system to achieve emission targets. SCR technology is an off-board after-treatment technology for vehicle diesel engines, which can effectively improve the emission of nitrogen oxides from diesel engines. [0003] SCR technology is a complete set of post-treatment process for diesel engine exha...
