Soil box for evaporative desorption process

摘要

Simple flow path with minimum turns for the vapor extraction flow paths can provide maximum air flow with minimal head loss, leading to higher efficiency in a thermal desorption process. Hot air vapor extraction arrangement can include large diameter vertical or horizontal trunk line or curved plate with continuous wire wrap well screens. The vapor extraction trunk can draw all vapors to the center of the soil box, which can reduce the treatment time by substantially removing condensation zone. The interior of the vapor extraction well screen and trunk can include porous material, which can reduce dust within the vapor stream, eliminate potential short circuiting in the event of a screen rupture and reduce potential explosion hazards.

主权项

1. A soil box for a thermal desorption process, the soil box comprising
a container,
wherein the container comprises one or more walls,wherein the container comprises an inner volume for containing a material,wherein the container comprises an opening inlet,wherein the opening inlet is configured to accept a treatment gas to the container,wherein the container comprises an opening outlet,wherein the opening outlet is configured to exhaust the treatment gas from the container; a screen element coupled to the opening outlet,
wherein the screen element is configured so that the treatment gas forms a substantially uniform flow through the material on the path from the opening inlet to the opening outlet.
