Abstract

An ionization device used for gas detection relates to the technical field of ionization chambers. The ionization device includes an ionization chamber and an ultraviolet lamp arranged at one end of the ionization chamber; the ionization chamber is composed of first and second casings; the ionization chamber is internally provided with first and second ionization cavities; the tail ends of the first and second ionization cavities are provided with a filler cavity; the filler cavity is internally provided with light fillers; the first ionization cavity is separated from the second ionization cavity by a separator plate; the separator plate is sprayed with an anode; and the tail end of the ionization chamber is provided with first and second cathodes. The ionization chamber is divided into two parts, on the premise of the same effective detection volume, the electrode distance is decreased by 1 / 2, the total thickness of the sensor is not increased, the detection sensitivity is improved effectively, the detection efficiency is high, the structure is simple, arrangement is reasonable, and the manufacture cost is low.

Description

technical field [0001] The invention relates to the technical field of ionization chambers, in particular to an ionization device for gas detection. Background technique [0002] An ionization chamber is a detector that uses the ionization effect of ionizing radiation to measure ionizing radiation, also known as an ionization chamber. The ionization chamber consists of electrodes at different potentials and a medium between them. Ionizing radiation produces ionized ion pairs in the medium. Under the action of an electric field, the positive and negative ions drift to the negative and positive electrodes respectively, forming an ionization current. Since the ionizing current is proportional to the intensity of the radiation, the intensity of the ionizing radiation can be obtained by measuring the current. According to the type of medium, the ionization chamber can be divided into air ionization chamber, liquid ionization chamber and solid ionization chamber, etc.; according...
