车用尿素桶
:本技术涉及尿素桶
,具体涉及一种车用尿素桶。
技术介绍
:车用尿素是无色、透明、清澈的液体,浓度为31.8%-33.2%,按照欧IV标准,目前32.5%为符合标准的车用尿素浓度。车用尿素用于还原氮氧化合物,可作为SCR(SelectiveCatalyticReduction,选择性催化还原)系统的还原剂,利用车用尿素水溶液与重型卡车、客车等柴油车尾气中的氮氧化物反应生成N2和H2O来净化尾气,使其排出的氮氧化物达到欧IV排放标准。车用尿素的工作原理是把车用尿素添加到SCR系统,在温度高于300℃的高温环境中,尿素分解成NH3,再加V2O5-TiO2、Ag-Al2O3、Cu-Zeolite等系列的催化剂的作用,尾气中的NOx能迅速与NH3反应生成N2和H2O,而柴油机的排气温度一般为300-500℃,满足了NOx氮氧还原所需的温度条件。目前的车用尿素桶安装不方便,经常导致桶体侧翻。而且目前尿素桶都只有一个出液口,在出液时容易造成气压不平衡而出液困难。
技术实现思路
:本技术所要解决的技术问题在于克服现有的技术缺陷,提供一种车用尿素桶。本技术所要解决的技术问题采用以下的技术方案来实现:一种车用尿素桶,包括具有容腔的箱体,所述箱体内设置用于盛放尿素的密封塑料袋,所述塑料袋侧部的开孔连接伸缩塑料管,所述箱体下部设有一圈围绕箱体的卡箍,卡箍两侧设有安装板,安装板下端面设有带有外螺纹的连接套,安装板上设有穿透安装板和连接套的通孔,通孔内插有拉杆,拉杆下部设有螺纹并螺纹连接有连接片,连接片上端面固定连接弹簧的一端,弹簧另一端固定连接到与连接套螺纹连接的旋钮, ...
