METHOD AND APPARATUS FOR CONTROLLING FECAL ODORS

摘要

Methods and apparatus for controlling fecal odors in an enclosed space, such as a pit latrine, include providing an oxidizer, such as a catalytic heater and an optional mechanical ventilation unit, such as an inline fan, both flow connected to a vault (pit) of the latrine. The heater is also connected to a source of fuel, for example, propane. Fresh air is drawn through vents in the latrine housing and thereafter through toilets in the latrine and through the vault, providing oxygen for the reaction. The fan and/or oxidation process draws both fresh air and accompanying odorous compounds directly from the latrine and into the oxidizer wherein the odorous components are substantially destroyed.

主权项

1. A method of forming a system for controlling fecal odor within a substantially enclosed space in fluid communication with a vault, wherein the vault is configured to store solid and liquid waste, wherein the method comprises:
providing a flameless heater configured to perform an oxidation reaction on odorous air to produce deodorized air; fluidly connecting the vault with the flameless heater using a first conduit positioned between the vault and the flameless heater, such that the flameless heater is in fluid communication with the substantially enclosed space via the first conduit and the vault; attaching a second conduit to the flameless heater, wherein the second conduit is configured to emit the deodorized air from the flameless heater; and positioning at least one fan within the first conduit between the vault and the flameless heater, wherein the at least one fan is configured to draw in the odorous air from the vault and the substantially enclosed space, wherein the at least one fan is configured to direct the odorous air to the flameless heater.
