| titleOfInvention | Production device of formaldehyde with high concentration of 55%-65% |
| abstract | The utility model relates to the technical field of a formaldehyde production technology, in particular to a production device of formaldehyde with high concentration of 55%-65%. The device comprises an evaporator device, an oxidizer device, a high-concentration absorption tower device, a tail gas liquid seal groove device and a tail gas treater device which are sequentially connected, wherein the high-concentration absorption tower device is formed by combining three sections of absorption towers, four circulation sections including a first separating packing section, a second absorbing packing section, a third absorbing packing section and a fourth absorbing packing section are sequentially connected beside the high-concentration absorption tower device from the bottom up, a bubble cap section is arranged at the top of the high-concentration absorption tower device, circulation is not performed in the first separating packing section, but circulation is performed in the second absorbing packing section, the third absorbing packing section, the fourth absorbing packing section and the bubble cap section at the top of the tower. According to the formaldehyde absorption system of the device, a three-section absorption and four-section circulation type absorption manner is adopted, and the steam is introduced into, so that the concentration of produced formaldehyde can reach up to about 55%-65%, the economic input is low, and the production efficiency is high. |
