Description

Smoldering equipment for treating organic pollution medium in production line mode and smoldering treatment method
Technical Field
The invention belongs to the field of environmental management and environmental remediation, relates to smoldering equipment and a smoldering treatment method for an organic matter polluted medium, and particularly relates to smoldering equipment and a smoldering treatment method for controlling an organic matter polluted medium in a production line mode.
Background
The smoldering technology is applied to the field of environmental improvement and environmental remediation, is an advanced technology for relatively energy-saving treatment of various medium and heavy organic matter polluted media (such as various oil sludge, petroleum hydrocarbon polluted soil and the like), takes organic pollutants in the polluted media as fuel (sacrificial fuel can be supplemented when the content/concentration of the organic pollutants in the polluted media is low, combustion supporting is realized), and realizes the thorough treatment of the polluted media through flameless self-sustaining combustion.
Smoldering techniques may be applied in situ or ex situ, but require high permeability of the contaminated medium. The in-situ smoldering technology is suitable for medium and high permeability fields with heavy organic pollution degree. The ex-situ smoldering combustion is mainly applied to ex-situ treatment of medium and high-concentration organic polluted media, and the development of an equipment process for engineering application is emphasized.
At present, the development of ectopic smoldering equipment at home and abroad is still in an early state, and the equipment is mainly modular equipment which is put into engineering application and takes a ventilation heating bottom plate (having heating and ventilation functions and a key device for smoldering starting) as a core component to form a single module box body (similar to the size of a container) or a plurality of modules which are spliced and combined into a larger reaction box/reactor. The ventilating and heating bottom plate of the module device is generally designed into a whole with a box body for containing/stacking the polluted media/materials, even in order to ensure the sealing, the bottom ends of four walls of the box body are often welded with the bottom plate, thereby forming the condition that each reaction box body is provided with a set of ventilating and heating bottom plate, and the ventilating and heating bottom plate and the reaction box body can not be separated. The operation process of the smoldering reaction box body is that firstly, materials are charged; secondly, the heating bottom plate starts to work until the polluted medium is ignited, and the time consumption is short; thirdly, the heating bottom plate stops heating, but air inlet is continuous, the material stack body enters a flameless self-sustaining combustion process, a combustion surface is gradually pushed along the air inlet direction until the material stack body passes through the whole stack body, the process is influenced by multiple factors such as the height of the stack body, and the consumed time is long; fourthly, after smoldering is finished, cooling and discharging are carried out, and thus the completion of one batch is realized.
Another existing device is of a skid-mounted steamer type, the bottommost end of the device is a heating/air inlet chamber, 2 or more steamers containing polluted media are placed above the heating/air inlet chamber, the steamers are a set, and smoldering reaction is also carried out in batch. The equipment form is more suitable for pilot-scale demonstration or small-scale engineering.
No matter the modular smoldering equipment or the cage-drawer smoldering equipment is adopted, reheating is not needed in the continuous smoldering stage, only ventilation is needed, the heating bottom plate is in an intermittent use state, and the utilization rate is very low; the two equipment forms have high requirements on the stress of the equipment structure, the selected material specification is conservative, the structure is complicated, and the manufacturing cost is high; the modular equipment has low transportation convenience, poor equipment reutilization, difficult maintenance, short expected life and high material loading and unloading difficulty; most importantly, neither device form can realize a mechanized, automatic and production line type modern industrial production mode.
