How to Make Silver Formaldehyde Absorption Tower?

As a Formaldehyde Production Plant, let me share with you. Silver-method formaldehyde The main production method of formaldehyde in our country is silver-method formaldehyde. The mechanical equipment in the production of formaldehyde is constantly progressing and developing. The equipment in the process of silver-method formaldehyde production mainly includes reaction equipment and absorption equipment, and the absorption equipment mainly depends on absorption The tower is used to complete the work of cooling and absorption, while the traditional absorption tower has a simple structure and poor absorption and separation effect, and it is difficult to completely separate formaldehyde and alcohols. Therefore, the absorption tower needs to be improved and strengthened.

Formaldehyde Production Silver Process

Silver-method formaldehyde provides a silver-method formaldehyde absorption tower in response to the shortcomings of the prior art, which improves the absorption and separation effect of formaldehyde. The silver-method formaldehyde absorption tower includes a conversion section, a cooling section below the conversion section, an absorption section above the conversion section, the top of the tower above the absorption section, and the bottom end of the tower below the cooling section. The section, the conversion section, the absorption section and the top of the tower are all arranged in the cylinder; the conversion section is provided with a distributor, the distributor is a disc-trough distributor, located in the middle of the conversion section, and the cooling section cylinder wall There is an annular pipe on it. Further, a high-concentration formaldehyde absorbing filler layer is installed inside the absorption section, and the high-concentration formaldehyde absorbing filler layer is a Pall ring material to improve the absorption effect of formaldehyde.

What is the role of silver-method formaldehyde? Silver-method formaldehyde is a popular chemical product with a wide range of uses, simple production process and sufficient supply of raw materials. It is the backbone of the downstream product tree of methanol. The world's annual output is about 25 million tons. About 30% of methanol is used to produce formaldehyde. What is the role of silver method formaldehyde? At present, the main production method of formaldehyde in China is silver method formaldehyde production. The mechanical equipment in production is constantly progressing and developing. The equipment in the process of preparing formaldehyde by the silver method mainly includes reaction equipment and absorption equipment. The absorption equipment mainly depends on the absorption tower to complete the cooling and absorption work, while the traditional absorption tower has a simple structure and absorbs and separates. The effect is poor, it is difficult to completely separate formaldehyde and alcohol, so the absorption tower needs to be improved. But formaldehyde is an aqueous solution with a low concentration, which is not convenient for long-distance transportation from an economic point of view. Therefore, factories are generally set up near the main consumer market. Import and export trade is also very small. Industry mainly uses methanol oxidation method and natural gas direct oxidation method.
