Description

Technical Field

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

[0002] Formaldehyde is an organic chemical substance, also known as formic aldehyde; the formalin solution known to the public is actually a 37% formaldehyde aqueous solution with a strong antiseptic effect. Formaldehyde itself is colorless, but irritating to the mouth, eyes, nose, etc.; it is easily soluble in water and ethanol, with a boiling point of -19.5°C, but a volatility point of 19°C above zero; it is an important basic organic chemical raw material, but due to its low boiling point and active properties, it has high industrial packaging requirements, poor storage stability, difficult transportation, and inconvenient use; polyformaldehyde is an excellent substitute for industrial formaldehyde. High-quality polyformaldehyde has the characteristics of high purity, good water solubility, complete depolymerization, loose product, uniform particles, etc., and is known as an ideal source of pure formaldehyde.

[0003] According to a heat dissipation device for formaldehyde production disclosed in Chinese patent CN209355732U, external cooling water enters the heat dissipation chamber through the water inlet pipe and flows out from the water outlet pipe, and the outlet pipe is spirally arranged, thereby increasing the path of the mixed gas flowing in the shell, thereby increasing the time for the mixed gas to pass through the outlet pipe, and the diameters of the air guide pipe and the outlet pipe are both larger than the diameter of the inlet pipe, so that the flow rate of the mixed gas through the outlet pipe is less than the flow rate in the inlet pipe, thereby further increasing the time for the mixed gas to pass through the outlet pipe. The time for the mixed gas to pass through the outlet pipe is longer, thereby improving the speed and effect of the mixed gas heat dissipation and improving the practicality of the device; however, the utility model still has the following problems: formaldehyde will generate a certain amount of waste gas during the production process, and there is no structure for treating the formaldehyde waste gas. The direct discharge of formaldehyde waste gas will pollute the air and inhale it into the human body, which will also have a certain impact on the human body. Therefore, a heat dissipation device for formaldehyde production is proposed to solve the above-mentioned problems. Utility Model Content
