Description

Technical Field

Background Art

[0002] Waste liquid and waste gas incinerators are generally used to treat high-concentration organic waste liquid and organic waste gas. Through high-temperature incineration, the incineration removal rate can reach 99.9% and the incineration efficiency can reach 99.99%.

[0003] In conventional incineration processes, low calorific value waste liquid is usually pumped into the incinerator, and the flash point of the waste liquid is generally >50°C, which can ensure the safety of the feed; low-concentration waste gas (concentration <25% LEL) is pressurized by a fan and sent into the incinerator for incineration.

[0004] When waste liquid and waste gas enter the incinerator, in order to ensure that the materials enter the incinerator smoothly, it is usually necessary to set up a feeding device, namely a "dual-fluid spray gun" and a "waste gas nozzle". When the waste liquid and waste gas enter the incinerator through the feeding device, if the flash point is too low, the calorific value is too high, the concentration is too high and the oxygen supplementation and mixing are insufficient, it is very easy to cause uneven flame distribution in the furnace, flash explosion, flameout, incomplete combustion, CO exceeding the standard and other problems. In order to meet the 3T+1E principle of the incinerator, namely the incineration temperature, flue gas turbulence, excess air rate, and gas residence time, improvements are made to the feeding of low-flash-point waste liquid and flammable and explosive high-concentration waste gas.
