Abstract

The invention belongs to the indoor environment detecting field, in particular relating to a detecting system used for detecting chemical contamination of materials of indoor articles. The detecting system comprises a lab and a closed detecting cabin arranged in the lab, wherein the detecting cabin comprises a detecting cabin door, a stirring fan arranged at the inner top of the detecting cabin, an exhaust outlet arranged on the upper wall of the detecting cabin, and an air supply outlet arranged on the lower part of the side wall of the detecting cabin; a computer, a concentration sampler, a pressure sampler, a temperature and humidity sampler and a flow sampler are arranged in the lab, the computer is connected with the concentration sampler, the pressure sampler, the temperature and humidity sampler and the flow sampler; three pipelines are arranged at the airspace in the lab, wherein the first pipeline is provided with a first set of air handling equipment, the second pipeline is provided with a second set of air handling equipment, and the third pipeline is provided with an exhaust fan. The detecting system used for detecting chemical contamination of materials of indoor articles uses the air handling equipment to control the environment of the detecting cabin, in order to ensure temperature, humidity, background concentration, particulate matter concentration, mixedness and air output to reach standard, improve detecting quality for chemical contamination of the materials of the indoor articles and reduce the cost.

Description

technical field [0001] The invention belongs to the field of indoor environment inspection, in particular to a detection system for measuring the release of chemical pollutants from indoor articles and materials. Background technique [0002] Indoor chemical pollution has received more and more attention. Indoor chemical pollution is mainly manifested in the presence of a large number of volatile organic compounds (VOCs) in the indoor air. and other health hazards. Therefore, it is necessary to detect the VOCs emission of building materials, furniture, household and office appliances and other materials. Items such as furniture are generally large in size, and the emission of VOCs is usually low concentration. Therefore, a large detection chamber is required for full-scale VOCs emission detection of furniture, etc. There are many parameters that need to be controlled during the detection process, including temperature, pressure, humidity, Wind speed, air supply volume, bac...
