Technical Field

[0001] The present application relates to the technical field of detection equipment, and specifically to a detection equipment for formaldehyde production. Background Art

[0002] Formaldehyde, also known as formic aldehyde, is a colorless gas with a pungent odor. It is irritating to the human eyes and nose. It is easily soluble in water and ethanol. As an important chemical raw material, it is widely used. It can be used to produce chemical products such as trialdehyde resin, polyoxymethylene, hexamine and MDI. It is widely used in pesticides, disinfectants, wood processing, water treatment, coatings, medicines and dyes. After the production of formaldehyde raw materials is completed, detection equipment is generally required to detect the formaldehyde concentration of the raw materials.

Wind plate, when used, the utility model adds a fan to simulate normal air circulation, and at the same time facilitates the transportation of formaldehyde-containing gas emitted by the paint to the detection box, so as to facilitate the detection of formaldehyde emitted by the paint. However, since the indoor temperature of most buildings cannot be kept at a constant temperature for a long time, the existing detection device has a relatively single method for detecting paint, and only uses natural emission to detect formaldehyde gas. It is unable to detect the formaldehyde gas concentration emitted by the paint at different temperatures, and the detection effect is poor. Moreover, the formaldehyde gas inside the detection box is not purified and is directly discharged, which makes the formaldehyde gas easily pollute the nearby working environment, which is not conducive to use. Therefore, a detection equipment for formaldehyde production is proposed to solve the above-mentioned problems. Utility Model Content

In addition, the temperature sensor 6 can detect the temperature change inside the equipment box 1 in real time, so that the detection equipment can detect the formaldehyde gas concentration emitted by the formaldehyde raw material at different temperatures. When the formaldehyde gas concentration detection is completed, the staff pulls the baffle 8 outward to expose the purification box 2, and then starts the suction fan 9 to absorb all the formaldehyde gas into the purification box 2, and adsorbs and purifies it through the multi-layer activated carbon filter 10 fixedly connected to the inner side thereof, and then discharges it to the external environment through the outlet 11.
