Vaporizer with secondary flow path

摘要

A vaporizer for generating a vaporized chemical decontaminating agent. The vaporizer includes a primary flow path and a blower for conveying a carrier gas along the primary flow path. A secondary flow path has a first end fluidly connected to the primary flow path at a location upstream of the blower and a second end fluidly connected to the primary flow path at a location downstream of the blower. A heating element is disposed along the secondary flow path. A liquid flow path has a first end fluidly connected to a source of liquid chemical decontaminating agent and a second end fluidly connected to the secondary flow path. The liquid flow path injects the liquid chemical decontaminating agent into the secondary flow path at a location upstream of the heating element. The heating element vaporizes the liquid chemical decontaminating agent to form the vaporized chemical decontaminating agent.

1. A vaporizer for generating a vaporized chemical decontaminating agent to decontaminate a region, said vaporizer comprising:
a primary flow path having an inlet end and an outlet end; a blower for conveying a carrier gas along said primary flow path; a secondary flow path having a first end fluidly connected to said primary flow path at a location between said outlet end of said primary flow path and said blower and a second end fluidly connected to said primary flow path at a location between said inlet end of said primary flow path and said blower, wherein said carrier gas flows from said first end of said secondary flow path to said second end of said secondary flow path; a heating element disposed along said secondary flow path; and a liquid flow path having a first end fluidly connected to a source of liquid chemical decontaminating agent and a second end fluidly connected to said heating element, wherein said heating element vaporizes said liquid chemical decontaminating agent to form said vaporized chemical decontaminating agent.
