The invention relates to a preparation method of a low-temperature SCR denitration catalyst. The preparation method of the low-temperature SCR denitration catalyst adopts the following low-temperatureSCR denitration catalyst preparation equipment. The low-temperature SCR denitration catalyst preparation equipment comprises a soaking cylinder, a fixing device and lifting devices, the left side andthe right side of the soaking cylinder are symmetrically provided with the lifting devices. a fixing device is installed on the side, close to the soaking cylinder, of the lifting device and arrangedabove the soaking cylinder. A honeycomb carrier is repeatedly wetted through vertical reciprocating motion of the lifting device, so that the absorption speed of the honeycomb carrier to chemical liquid is increased. The absorption uniformity of the honeycomb carrier to the chemical liquid is guaranteed; through the connecting mechanism and the springing mechanism, the honeycomb carrier shakes upand down by utilizing the weight of the honeycomb carrier, so that the absorption uniformity of the honeycomb carrier to the chemical liquid is ensured, and the redundant chemical liquid absorbed inthe honeycomb carrier quickly flows out through shaking.

    本发明涉及一种低温SCR脱硝催化剂制备方法,该低温SCR脱硝催化剂制备方法采用如下低温SCR脱硝催化剂制备设备,该低温SCR脱硝催化剂制备设备包括浸泡缸、固定装置和升降装置,浸泡缸的左右两侧对称设置有升降装置,升降装置靠近浸泡缸一侧安装有固定装置,固定装置设置在浸泡缸上方。本发明通过升降装置上下往复运动对蜂窝式载体进行反复浸湿,加快了蜂窝式载体对化学液体的吸收速度,保证了蜂窝式载体对化学液体吸收的均匀性;通过连接机构和弹动机构利用蜂窝式载体自身的重量上下抖动,从而保证了蜂窝式载体对化学液体吸收的均匀性,以及通过抖动使蜂窝式载体内吸收的多余的化学液体迅速流出。
