Device for testing emission rate of pollutants in building material and use method of device

Abstract

The invention discloses a device for testing an emission rate of pollutants in a building material. The device comprises an air pump (1), wherein the output end of the air pump (1) is connected to the input end of a precision filter (2); the output end of the precision filter (2) is connected to a VOC (volatile organic compound) filter (3); the output end of the VOC filter (3) is connected with a humidity generator (4); the output end of the humidity generator (4) is connected to a test cabin (5); a flow control valve (6) and a gas flowmeter (7) are arranged on a connection pipeline of the humidity generator (4) and the test cabin (5) in sequence; a humidity and temperature meter (8) is arranged on a pipeline, which extends into the test cabin (5), of the output end of the gas flowmeter (7). According to the device disclosed by the invention, the emission rate of the pollutants in the building material and the release amount of VOCs in relevant light industrial products can be quickly detected; the device is convenient to operate; therefore, the quality of indoor air is subjected to comprehensive environment index evaluation by using indoor pollutant data or a forecasting model, and the indoor environment living quality of people is improved.
