Cooling water recovery treatment equipment for formaldehyde production

The invention belongs to the field of cooling water recovery treatment, and particularly relates to cooling water recovery treatment equipment for formaldehyde production. A gas inlet module provides formaldehyde gas and is connected with a liquid guide module, translation devices are arranged on the left side and the right side of the gas inlet module, and the liquid guide module is connected with a heating module through a conveying pipeline. According to the invention, formaldehyde gas can be efficiently collected from liquid through recycling of the two separated test-tube-shaped heating devices. Formaldehyde gas in the liquid enters the condensation tank and then is conveyed to the separation test-tube-shaped heating device through the U-shaped tube, and the active adsorbent absorbs the formaldehyde gas. The device is provided with a servo motor and a temperature sensor, and the position of the heating device is accurately controlled to ensure the formaldehyde gas collection efficiency. The operation pro
