The utility model is the device that a kind of methanol oxidation is produced formaldehyde.Belong to the device for preparing formaldehyde with oxidization of methanol.
Background technology
Formaldehyde is one of most important organic synthesis raw material in the chemical industry, is used for macromolecular compounds such as the bigger fluoropolymer resin of production market demand, polyacetals; In the process units of all more important chemical products such as synthesis of pentaerythritol, trimethylolpropane, neopentyl glycol, hexa, ethylenediamine tetra-acetic acid,, be used in a large number as primary raw material.In addition, the application aspect disinfectant, anticorrisive agent, cosmetics is also very extensive.And consumption constantly increases.In contrast, the market shrink of acetaldehyde, consumption reduces, and there is the idle situation of acetaldehyde device in many enterprises.
In the prior art, there is following deficiency in the device that formaldehyde is produced in the methanol oxidation dehydrogenation:
1. formaldehyde uses water as absorbent, adopts the double tower circulation to absorb flow process, and the absorption efficiency of formaldehyde is low, the marrow exhaust emissions, and loss is higher.
2. exhaust combustion is handled, resource and thermal waste, and contaminated environment.
3. catalyst for catalytic oxidation is short service life.
3. it is bigger newly to go up a complete set of formaldehyde plant investment.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art; and provide a kind of formaldehyde absorptivity height; tail gas resource, heat energy recycle, help environmental protection, the methanol oxidation of catalyst for catalytic oxidation long service life is produced the device of formaldehyde.
The purpose of this utility model also is simply to transform through to idle acetaldehyde device, can be applicable to the demand of methanol oxidation production formaldehyde for process units, saves equipment investment.
The purpose of this utility model can reach by following measure:
Methanol oxidation of the present utility model is produced the device of formaldehyde, it is characterized in that the acetaldehyde commercial plant is produced in idle oxidation of ethanol, simply transforms to form, and transformation project is as follows:
A. the cover of one in the oxidation that be arranged in parallel in the former design, absorption plant all devices all adopts;
B. the another set of oxidation, the absorption plant that be arranged in parallel only are used the 3rd absorption tower 10 devices of its second absorption tower device as formaldehyde plant; The setting of formaldehyde the 3rd absorption tower system has improved the assimilation effect of formaldehyde.
C. from the tail gas on the 3rd absorption tower 10 through linking together by pipeline and pipe fitting of newly establishing by tail gas separator 16, waste heat boiler 17, blower fan 18, drum 19, water-line 20 and steam output pipe line 21
The exhaust combustion waste heat boiler device of forming reclaims heat energy; Economize on resources the protection environment.
D. newly-increased methanol feeding filter 14 and formaldehyde recursive filter 15.Reduce the impurity content of the system that enters, effectively prolonged the service life of catalyst.
The purpose of this utility model can also reach by following measure:
Methanol oxidation of the present utility model is produced the device of formaldehyde, it is characterized in that the 3rd absorption tower 10 devices of the formaldehyde plant described in the b, also can process again according to specification requirement.
The device that methanol oxidation of the present utility model is produced formaldehyde can produce following good effect compared to existing technology:
1. a kind of formaldehyde absorptivity height is provided, tail gas resource, heat energy recycle, has helped environmental protection, the methanol oxidation of catalyst for catalytic oxidation long service life is produced the device of formaldehyde.
2. through to idle acetaldehyde device, simply transform, can be applicable to the demand of methanol oxidation production formaldehyde, save equipment investment for process units.
3. the setting of formaldehyde the 3rd absorption tower system has improved the assimilation effect of formaldehyde.
4. the setting of tail gas waste heat boiler promptly economizes on resources, and protects environment again.
5. newly-increased methanol feeding filter 14 and formaldehyde recursive filter 15.Reduce the impurity content of the system that enters, effectively prolonged the service life of catalyst.
