Abstract

The invention relates to the technical field of waste gas purification devices, in particular to a leachate back-spraying system of a waste incineration boiler and a method for reducing the NOx content. A conveying assembly is connected with a sedimentation tank; a conveying pipe is connected with the conveying assembly; a spraying pipe is communicated with the conveying pipe; the spraying pipe is communicated with a hearth; a mounting block is connected with the spraying pipe; a fixing block is connected with the conveying pipe; two first reset springs are connected with the mounting block; two connecting rods are connected with the two first reset springs; two second reset springs are connected with the two connecting rods; and two abutting blocks are connected with the two second reset springs. The second reset springs push the abutting blocks out of the connecting rods so that the fixing blocks on the conveying pipe can be clamped between the abutting blocks and the mounting block, the first reset springs pull the conveying pipe on the fixing block through the abutting blocks in the direction of the spraying pipe, and thus, the conveying pipe is fixed to the spraying pipe. The problem that the connecting end of the conveying pipe and the spraying pipe is disconnected due to vibration generated when leachate flows in the conveying pipe and the spraying pipe is solved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification devices, in particular to a leachate respray system for a waste incineration boiler and a method for reducing NOx content. Background technique [0002] There are two ways of waste disposal: one is to use landfill technology, and the other is to incinerate domestic waste, which is incinerated in a boiler with domestic waste, which has the advantages of reduction, resource utilization and harmlessness. The steam generated It can be used for power generation and steam supply, which has the social benefits of saving energy and reducing environmental pollution, and also has good economic benefits. The leachate in the garbage is treated through the leachate return spray system of the waste incineration boiler; [0003] The delivery pump of the existing waste incineration boiler leachate return spraying system transports the leachate in the sedimentation tank to the nozzle through the d...
