Novel efficient catalyst equipment for environmental protection

Abstract

The invention discloses novel efficient catalyst equipment for environmental protection. The novel efficient catalyst equipment comprises a fixed seat and a denitration shell, wherein the outer side of the denitration shell is annularly connected with an annular plate; four corners of the annular plate are respectively and fixedly connected with a supporting rod; denitration space is arranged at the inner part of the denitration shell; multiple groups of denitration catalyst modules are arranged at the inner part of the denitration space; one spray-wash regeneration device is arranged at the right side of the upper end of each denitration catalyst module; a hydraulic pump is arranged on the upper end of the right end surface of the denitration shell. When the novel efficient catalyst equipment disclosed by the invention is in work, a regenerant can be pumped through the hydraulic pump and can uniformly flow to second atomization spray nozzles under the action of flow diversion plates,rotation of a flow diversion shell is limited through the matching of sliding limiting blocks and sliding grooves, an SCR (Selective Catalytic Reduction) regenerant can be sprayed to the denitration catalyst modules through the second atomization spray nozzles, on one hand, accumulated soot particles on the denitration catalyst modules can be flushed and removed, on the other hand, the denitrationcatalyst modules can be treated through the SCR regenerant, and repeated dismounting for cleaning is not required.

Description

technical field [0001] The invention relates to the field of environmental protection and denitrification, in particular to a novel high-efficiency catalyst equipment for environmental protection. Background technique [0002] At present, selective catalytic reduction technology, referred to as SCR denitrification technology, is the most widely used and mature flue gas denitration technology in the market. It mainly uses NH3 as the reducing agent to neutralize nitric acid. The core is the catalyst module, and the catalyst module During use, the activity will gradually decrease, and the particles in the flue gas will block the catalytic module, resulting in a decrease in the catalytic effect and denitrification efficiency. If the deactivated catalyst is regenerated, the cost of denitrification will be greatly reduced. In the prior art , the regeneration of the catalyst is done by shutting down the machine, hoisting the catalyst module out of the reactor, and then transporting...

[0002] At present, selective catalytic reduction technology, referred to as SCR denitrification technology, is the most widely used and mature flue gas denitration technology in the market. It mainly uses NH3 as the reducing agent to neutralize nitric acid. The core is the catalyst module, and the catalyst module During use, the activity will gradually decrease, and the particles in the flue gas will block the catalytic module, resulting in a decrease in the catalytic effect and denitrification efficiency. If the deactivated catalyst is regenerated, the cost of denitrification will be greatly reduced. In the prior art , the regeneration of the catalyst is done by shutting down the machine, hoisting the catalyst module out of the reactor, and then transporting it to the manufacturer for processing. During the project, it consumes a lot of manpower, material resources, and financial resources, and also affects the operation of the device. Moreover, the catalyst module is generally thin-walled. In the process of handling, it is easy to be damaged, causing a lot of property loss
