specific Embodiment approach

[0048] The specific implementation method is to carry out pretreatment such as sorting, crushing and mixing of industrial waste, put the waste that can be incinerated after pretreatment into the incinerator, control the temperature in the incinerator, burn the waste into flue gas, and first pass through the The heat exchange device and the quenching device reduce the temperature of the flue gas, and recover the waste heat to the waste heat recovery device through the heat exchange device; the flue gas after quenching treatment passes through the deacidification device to remove the acid gas; and then passes through the bag filter to remove Solid soot particles in the flue gas; and then through the spray device, the acid gas and water-soluble dust particles in the flue gas are washed and collected into the waste liquid collection pool; and then removed by the electrostatic demist device The dust particles smaller than 2 μm that cannot be removed by the bag filter and the water m...

Abstract

The invention discloses an industrial waste high-temperature incineration flue gas purification treatment process. The treatment process comprises the following steps that (1), industrial waste is pretreated; (2), the waste is loaded into an incinerator, and the temperature in the incinerator is controlled to burn the waste; (3), the flue gas temperature is lowered through a heat exchange device;(4), the flue gas temperature is lowered again through a quick cooling device; (5), acid gas in the flue gas is removed through a deacidification device; (6), solid smoke particles in the flue gas areremoved through a dedusting device; (7), the acid gas and the water-soluble tiny dust particles in the flue gas are washed with a spray device and collected into a waste liquid collection pool; (8),the tiny dust particles and the water mist obtained after spray washing are removed through an electrostatic demisting device; (9), harmful gases such as dioxin in the flue gas are removed through anadsorption device; (10), the flue gas can be discharged when the flue gas is detected to meet the standards through a detection device. The process is simple, high in operability and obvious in flue gas purification effect, and automated operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of industrial waste incineration exhaust gas treatment, and in particular relates to a process for purifying industrial waste high-temperature incineration flue gas. Background technique [0002] Flue gas incineration refers to the use of flue gas incineration to burn and oxidize the pollutants in the flue gas. The types and concentrations of pollutants in incineration flue gas are affected by many factors such as the composition of industrial waste and combustion conditions, and the production mechanism of each pollutant is also different. [0003] Industrial waste is burned in the incinerator to produce flue gas. The characteristics of incineration flue gas are: [0004] (1) The exhaust gas temperature of the incineration flue gas is high. [0005] (2) There are many kinds of pollutants in the incineration flue gas. In addition to generating conventional air pollutants such as sulfur dioxide, nitrogen o...
