Embodiment 1

[0032] Example 1: Such as figure 1 As shown, the mobile pollutant waste thermal desorption complete set of equipment includes a feed module, a thermal phase separation module, a discharge module, a water treatment module, and an exhaust gas treatment module; the feed module is connected to the thermal phase separation module, and The thermal phase separation module is respectively connected with the discharge module, the water treatment module, and the exhaust gas treatment module, and the exhaust gas treatment module is connected with the water treatment module.

[0033] The feed module includes a pulverizer 1, a closed belt conveyor 2 and a screw feeder 22; the discharge port of the pulverizer 1 is in communication with the input end of the closed belt conveyor 2, and the closed belt conveyor 2 The output end of the screw feeder 22 is connected to the feed port;

[0034] The thermal phase separation module includes a drying kiln I3, a drying kiln II4, and a mixed gas warehouse 2...

Embodiment 2

[0044] Embodiment 2: The structure of this embodiment is the same as that of Embodiment 1. The difference is that the bag filter 14 is a pulse-type bag filter, and the bag filter 14 can also introduce compressed air through the air duct. The bag filter 14 The bottom of the ash hopper is provided with a manual flap valve and a heavy hammer type ash unloading valve. The side wall of the ash hopper is provided with an inspection hole and an ash stabbing port; the condenser 15 is a glass tube condenser. The tube group is installed vertically, the steam travels through the tube pass, and the condensate travels through the shell pass to form a reverse convection heat exchange form. The maximum temperature difference: ≤120°; the feed module, thermal phase separation module, discharge module, and water treatment The equipment of the module and the exhaust gas treatment module are all installed on a base, and the base is movable; a mist removal tower is added between the scrubbing tower ...

Abstract

The invention movable type complete equipment for thermal desorption of polluted waste and a method. The complete equipment comprises a feeding module, a hot phase separation module, a discharging module, a water treatment module and a waste gas treatment module. The complete equipment fills up a vacancy in domestic thermal desorption advanced technology. The problem of governing polluted waste (soil) containing mercury, arsenic, organic matters, organic pesticides and the like can be solved rapidly and efficiently by the complete equipment for thermal desorption. The complete equipment for thermal desorption has the beneficial effects that environmental safety is good, the application range of a material is wide, and the thermal desorption temperature is low. The manner of condensation isadopted in the waste gas treatment module to recycle the organic matters, arsenic and mercury in the polluted waste (soil); reutilization of resources is achieved; higher energy recycling efficiencyis achieved; circulation inside the equipment is achieved after waste water is treated; natural gas or light diesel is adopted as the fuel; and pollutant content in the discharged tail gas is little.The movable type complete equipment for thermal desorption of polluted waste is more environmentally friendly and has a wide application prospect.

Description

Technical field [0001] The invention relates to a complete set of equipment and method for thermal desorption of mobile polluted waste, and belongs to the technical field of thermal separation equipment. Background technique [0002] Soil thermal desorption remediation refers to the use of thermal volatility of pollutants, using direct or indirect heating methods to increase soil temperature (150 ~ 760 ℃), and promote the preferential distribution of pollutants in the gas phase at the water-gas and solid-gas interfaces Therefore, pollutants (such as mercury or organic matter) are resolved from the soil, and further advanced treatment is carried out by recovering volatilized gaseous pollutants, including bag dust removal, filtration, re-incineration, activated carbon adsorption and other measures to achieve emission standards Discharge, the treated soil is finally backfilled by adding water to cool it down, so as to realize the purification and restoration of the contaminated soil...
