Integrated combustor suitable for incineration of high-salinity organic wastewater

Abstract

The invention discloses a combustor which comprises a shell, a first air inlet assembly, a second air inlet assembly and a wastewater spray gun. The shell comprises a wind box front plate, a wind boxback plate, a wind box partition plate, a wind box side plate, a central cylinder, a spray gun fixing pipe I, a cyclone, an inner throat fixing plate, an inner ring throat straight section, an inner throat flaring section and an outer throat. An air inlet is formed in the wind box side plate, and the air inlet is divided into two air inlet channels. The central cylinder is perpendicular to the wind box partition plate, the spray gun fixing pipe I is arranged in the central cylinder and is coaxial with the central cylinder, and the cyclone sleeves the spray gun fixing pipe I. The first air inlet assembly comprises a spray gun fixing pipe II, a sleeve, an inner ring gun, an outer ring gun and a panel, and a spray gun rod of the wastewater spray gun penetrates through the spray gun fixing pipe II and the spray gun fixing pipe I. The combustor is an integrated combustor suitable for incineration of high-salinity organic wastewater, and is compact in structure, good in wastewater atomization effect, stable in ignition and combustion and high in combustion efficiency.

Description

technical field [0001] The invention relates to an incineration treatment technology, in particular to a waste water incinerator. Background technique [0002] The treatment of wastewater containing organic matter and high-concentration salt (hereinafter referred to as high-salt wastewater) produced by the chemical industry has always been a major problem in the field of environmental protection. These wastewaters usually not only contain a variety of acids, aldehydes, alcohols, olefins and other organic substances (or combustibles), but also a large amount of Na + 、K + , Ca 2+ , Cl - , F - , SO 2- 4 and other salt components. Direct discharge of high-salt organic wastewater will seriously pollute the environment. High-salt wastewater generally inhibits the growth of biological bacteria, resulting in poor degradation treatment effects of existing biochemical treatment technologies for this type of wastewater. The process of treating high-salt wastewater by physical ...

Problems solved by technology

Therefore, the existing wastewater incineration technology still has deficiencies, for example, the heat released by the combustion of auxiliary fuel and wastewater is not fully utilized, the evaporation time of wastewater water is long, it is difficult to catch fire, the combustion effect is poor, and the burnout time is long, which also reduces the volume of the incinerator. also relatively large
