Embodiment 1

[0029] This embodiment discloses a method for chlorine-containing waste liquid, waste gas incineration and tail gas treatment, comprising the following steps:

[0030] Step 1. First raise the furnace temperature of the incinerator to 900-1000°C, then connect the industrial waste gas stored in the gas storage tank to the incinerator, mix it with the combustion-supporting gas in the incinerator, and incinerate; wherein, the above-mentioned gas storage The cabinet is a double-membrane gas storage cabinet, and the pressure range of the output exhaust gas of the double-membrane gas storage cabinet is 10-20KPa; the above-mentioned exhaust gas and combustion-supporting gas are mixed in the multi-gas blending burner before entering the incinerator, The incineration burner is set at the top of the incinerator, the multi-gas blending burner is a coaxial multi-tube structure, and the outlet of the multi-gas blending burner is provided with a vortex to enhance gas mixing;

[0031] Step 2:...

Embodiment 2

[0038] The difference from Example 1 lies in the devices for chlorine-containing waste liquid, waste gas incineration and tail gas treatment.

[0039] A chlorine-containing waste liquid, waste gas incineration and tail gas treatment device in this embodiment includes an incinerator, a double-membrane gas storage cabinet, a multi-gas blending burner, a waste heat boiler, a hydrochloric acid falling film absorption system, a hydrogen peroxide denitrification system, and an alkali cleaning Tower systems, exhaust fans and chimneys.

[0040] Among them, the incinerator in step one is composed of a vertical section and a horizontal section. The vertical section is provided with a waste water feeding port, a gas burner interface, a fire sight glass, and a pressure and temperature source casing. The vertical section is used for Feeding, gas-liquid mixing and oxygen-enriched combustion;

[0041] A secondary air inlet for secondary combustion is provided on the horizontal section, and ...

Abstract

The invention relates to a method for burning chlorine-containing waste liquid and chlorine-containing waste gas and treating tail gas. The method comprises the steps of furnace baking, burning of thewaste liquid and the waste gas, recycling of waste heat, removing of chlorine in a rapid cooling mode, nitrogen removing through hydrogen peroxide and alkaline cleaning for dust removing. Various forms of dangerous waste are treated through an incinerator, adaptability is high, operation is easy, safety and reliability are achieved, and operation is stable. The flue gas is subjected to removing of chlorine in a rapid cooling mode, removing of nitric oxide and alkaline cleaning for dust removing in sequence and then discharged into atmosphere, and the purpose of recycling a heat source is alsoachieved while environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for incinerating chlorine-containing waste liquid, waste gas and tail gas. Background technique [0002] With the rapid development of my country's economy, the prosperity of industrial and agricultural production, and the popularization of the medical system, a large amount of solid waste such as medical waste, hazardous waste, domestic waste, organic biomass, and sludge has been produced, causing serious pollution to the environment. . [0003] Garbage incineration is a clean solid and liquid waste harmless and reduction treatment technology. As we all know, if the high-temperature flue gas after waste solid and waste liquid incineration is directly discharged into the atmosphere, it will cause great environmental pollution and cannot meet the requirements of energy conservation and environmental protection. [0004] Waste is a potential resource, a...
