Problems solved by technology

[0002] At present, most domestic waste incineration power plants adopt other current leachate treatment processes, which often have many shortcomings: for example, using traditional sewage physical and chemical methods or biological methods to treat landfill leachate is not only ineffective, but also difficult to meet the national sewage discharge standards. At the same time, it covers a large area and takes a long time to build; while using MBR (membrane + biochemical combination) process including nanofiltration, reverse osmosis, etc. for treatment, there are high investment, complicated process, high operation and maintenance costs, and post-treatment Various problems such as secondary pollution caused by the inability of the concentrated solution to continue to decompose

Abstract

The invention relates to an atomizing spray gun. Four leachate return and spray nozzles are arranged on two sides of the outlet sidewall of a burning hearth furnace and are parallel to a secondary air inlet. The atomizing spray gun comprises a compressed air nozzle, a leachate nozzle, a flange, a protective sleeve, a gun rod and an atomizing nozzle. The compressed air nozzle is screwed to the larger end of the leachate nozzle in a threaded manner, the gun rod is screwed to the smaller end of the leachate nozzle in a threaded manner, and one end of the atomizing nozzle provided with a thread is screwed to the outer thread of one end of the gun rod. The gun rod is fixed to the flange in a welded manner, and the flange is sleeved with a seal ring. One end of the protective sleeve with a mounting hole sleeves the flange and is fixed through a screw to prevent from dropping. The atomizing spray gun has the advantages that dual-fluid design is adopted, the leachate and the compressed air are mixed in the nozzle under certain pressure, fine atomized particles are produced, and service life is super long.

Description

technical field [0001] The invention relates to the field of leachate back-spraying treatment, and is mainly used for an atomizing spray gun in a leachate back-spraying treatment system of a waste incineration power plant. Background technique [0002] At present, most domestic waste incineration power plants adopt other current leachate treatment processes, which often have many shortcomings: for example, using traditional sewage physical and chemical methods or biological methods to treat landfill leachate is not only ineffective, but also difficult to meet the national sewage discharge standards. At the same time, it covers a large area and takes a long time to build; while using MBR (membrane + biochemical combination) process including nanofiltration and reverse osmosis for treatment, there are high investment, complicated process, high operation and maintenance costs, and post-treatment The concentrated solution cannot continue to decompose and cause various problems s...
