Movable multifunctional module thermal desorption system

Abstract

The invention relates to a movable multifunctional module thermal desorption system. Equipment of the system is divided into three modules; the module I comprises a thermal desorption rotary kiln 1; the module II comprises a cyclone dust collector 2, a secondary combustion chamber 3, a heat exchanger 4, a spray cooling tower 5, an alkali absorption tower 7, an automatic control system 13 and a steam-water separator 14; the module III comprises a bag type dust collector 6, an activated carbon absorber 8, a biofilter 9, an induced draft fan 10, an exhaust device 11 and a booster fan 12; the equipment of the module I, the module II and the module III are respectively arranged on movable equipment. The system is suitable for four process routes including high-concentration and high-toxicity organic compound contaminated sites, general volatile/semi-volatile organic compound contaminated sites, acidic organic compound contaminated sites and organic sulfide and ammonia-nitrogen organic compound contaminated sites; different process routes and equipment can be accurately and effectively provided according to different organic compound contaminated sites, so that the time for designing a technical route is reduced, and the transportation and onsite loading and unloading are convenient.

Description

technical field [0001] The invention relates to a mobile multifunctional module thermal desorption system, which can deal with the desorption of organic pollutants on site by selecting various process routes to achieve a system for purifying flue gas and soil. Background technique [0002] At present, the domestic site restoration industry is still in the initial stage of development, and the understanding of system construction and site restoration technology is relatively rough. There are no specific norms and technical standards to provide reference, and the technology is relatively immature. With the vigorous development of our country's economy, the country pays more and more attention to environmental issues, especially the construction of ecological civilization has been mentioned on the national development agenda. Many industrial sites have been relocated due to various reasons or the contaminated soil left over from history, especially the soil contaminated by orga...
