Problems solved by technology

Honeycomb catalyst regeneration mainly adopts methods such as soot blowing, cleaning, and immersion activity recovery. Among them, in the cleaning process, the traditional honeycomb regeneration technology is to rinse the catalyst vertically in each tank, but this method not only has a long rinse cycle, but also The cleaning water needs to be replaced regularly to ensure the cleaning effect, the operation is cumbersome, the cleaning efficiency is low, and the cost is high

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, a channel-type countercurrent regeneration system for catalysts of the present invention includes a cleaning channel 1 arranged in a back shape, and a lifting water pump 2 and a lifting water pump 3 are arranged in the cleaning channel 1, and the lifting water pump 2 and the lifting water pump 3 are respectively arranged On the opposite sides of the cleaning channel 1, to ensure the circulation of the water flow in the cleaning channel 1, it can ensure the continuous operation of cleaning and improve the regeneration effect; the cleaning channel 1 is equipped with a liquid medicine supply device to supply the medicine and liquid to the cleaning channel. In the canal 1; after the catalyst 4 is placed on the cleaning rack 5, it is immersed in the cleaning canal 1, and the hardened end of the catalyst 4 (that is, the end of the catalyst 4 in the conventional flue gas contact direction) is arranged opposite to the direction of the wate...

Abstract

The invention provides a canal type countercurrent regeneration system for a catalyst. The canal type countercurrent regeneration system is easy to operate, high in cleaning efficiency, low in cost and capable of guaranteeing the cleaning effect. The system comprises a cleaning channel arranged in a concentric-square shape, and at least one lifting water pump is arranged in the cleaning channel so as to guarantee circulating flow of water flow in the cleaning channel; a liquid medicine supply device is arranged on the cleaning channel so as to supply liquid medicine and liquid medicine into the cleaning channel; the catalyst is immersed in the cleaning channel after being placed on the cleaning frame, and the hardened end of the catalyst is arranged opposite to the direction of water flow in the cleaning channel so as to perform countercurrent flushing on the hardened end of the catalyst.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a channel-type countercurrent regeneration system for catalysts. Background technique [0002] According to the National Environment Office Letter [2014] No. 990 "Notice on Strengthening the Supervision of Waste Flue Gas Denitrification Catalysts", the waste flue gas denitrification catalyst (vanadium-titanium series) is officially included in the management of hazardous waste, and it is required to improve the waste flue gas denitrification as soon as possible. Regeneration, utilization and disposal capabilities of catalysts (vanadium-titanium series). At present, the domestic waste catalyst disposal and utilization method is mainly to give priority to regeneration, and the catalysts that cannot be regenerated are extracted from the active components such as titanium, tungsten, and vanadium in the catalyst for resource utilization. Honeycomb catalyst regeneration ...
