Problems solved by technology
[0004] (1) In the process of wetting the honeycomb carrier, if the honeycomb carrier is directly soaked in the chemical liquid, in a static state, the absorption speed of the honeycomb carrier is slow, and when the edge position is full, the middle part The location has not yet absorbed the chemical liquid, thus resulting in uneven absorption of the cellular carrier
[0005] (2) When the honeycomb carrier is completely soaked and taken out, the excess chemical liquid in the honeycomb carrier will gradually drip down. Due to the large area of the lower end of the honeycomb carrier, the dripping speed is too slow, so it takes more time

The invention relates to a low-temperature SCR denitration catalyst processing and preparation system. The low-temperature SCR denitration catalyst processing and preparation system adopts the following low-temperature SCR denitration catalyst preparation equipment. The low-temperature SCR denitration catalyst preparation equipment includes a soaking tank, a fixing device and a lifting device. The left and right sides are symmetrically provided with a lifting device, and a fixing device is installed on one side of the lifting device close to the soaking tank, and the fixing device is arranged above the soaking tank. The invention repeatedly soaks the honeycomb carrier through the up and down reciprocating motion of the lifting device, which speeds up the absorption speed of the chemical liquid by the honeycomb carrier and ensures the uniformity of the chemical liquid absorption by the honeycomb carrier; The weight of the honeycomb carrier itself shakes up and down, thereby ensuring the uniformity of the chemical liquid absorbed by the honeycomb carrier, and the excess chemical liquid absorbed in the honeycomb carrier flows out quickly through shaking.
Description
technical field [0001] The invention relates to the technical field of SCR denitration catalysts, in particular to a low-temperature SCR denitration catalyst processing and preparation system. Background technique [0002] SCR denitrification catalyst generally refers to the catalyst used in the SCR denitrification system of the power plant. In the SCR reaction, the reducing agent is selectively reacted with the nitrogen oxides in the flue gas at a certain temperature. The catalyst type can be divided into three types. Types: plate type, honeycomb type and corrugated plate type. [0003] This equipment is aimed at the honeycomb carrier. During the catalyst preparation process, the honeycomb carrier needs to be soaked in a chemical liquid so that the honeycomb carrier can be completely absorbed. However, the following problems generally exist in the process of wetting the honeycomb carrier : [0004] (1) In the process of wetting the honeycomb carrier, if the honeycomb carr...
