Efficient catalyst device for environmental protection

Abstract

The invention discloses an efficient catalyst device for environmental protection. The efficient catalyst device comprises a fixing base and a denitration housing, wherein the outer side of the denitration housing is annularly connected with an annular plate, four support rods are fixedly connected to four corners of the annular plate, and the denitration housing is internally provided with denitration space; a plurality of sets of denitration catalyst modules are arranged in the denitration space, a spray-wash regenerating device is disposed on the right side of the upper end of each denitration catalyst module, and a hydraulic pump is arranged at the upper end of the right end surface of the denitration housing. When the device is in use, regenerant which is pumped by the hydraulic pumpflows uniformly towards second atomizing nozzles under the action of splitter plates, rotation of splitter housings is restricted through cooperation of sliding stop blocks with sliding grooves, and the SCR regenerant is sprayed onto the denitration catalytic modules through the second atomizing nozzles, so that soot particles which accumulate on the denitration catalytic modules are rinsed off onthe one hand, the denitration catalytic modules are treated through the SCR regenerant on the other hand, and no repeated destuffing and cleaning are needed.

Description

technical field [0001] The invention relates to the field of environmental protection and denitrification, in particular to a 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 it to...

[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
