Description
Technical field
This utility model is related to ferrum molybdenum formaldehyde production field, particularly a kind of formaldehyde process units.
Background technology
Formaldehyde is one of important source material of Organic Chemical Industry, is widely used in Wood industry, textile industry, listerine
Etc. industry.Formaldehyde Production mainly has two kinds of techniques of Yin Fa and ferrum molybdenum method at present, introduces behind the country from ferrum molybdenum method production formaldehyde technology,
Domestic Formaldehyde Production no longer relies only on silver-colored method production formaldehyde.Not only conversion ratio is low for silver-colored method production formaldehyde, and first in formaldehyde products
Alcohol content up to 2 ~ 3%, reaction temperature is high, and operating condition is harsh.Ferrum molybdenum method produces formaldehyde, and high conversion rate, catalyst activity are high,
Operating condition is gentle, and in product, methanol content is low.And catalyst is nontoxic, it is easy to recycling.With formaldehyde market
Demand it is growing, downstream PARA FORMALDEHYDE PRILLS(91,95) prescription gradually increases, and ferrum molybdenum method gradually instead of conventional silver method at home.Ferrum
The molybdenum catalyst market demand increases therewith.Iron-molybdic catalyst all source imports, World Catalyst delivery cycle are long, and price is held high
It is expensive, and formality is loaded down with trivial details, and as the market demand gradually increases, contradiction is more highlighted.
The content of the invention
The purpose of this utility model is the deficiency that customer service prior art is present, there is provided a kind of production of ferrum molybdenum formaldehyde
Device.This utility model is safe and reliable, is applicable to all iron-molybdic catalysts, including the iron-molybdic catalyst of production domesticization.
The technical solution adopted in the utility model：This utility model is related to a kind of process units of ferrum molybdenum formaldehyde, including

Formaldehyde reactor（6）, heat conduction oil condenser（7）, in methyl alcohol vaporizing device（5）After formaldehyde absorbing tower is set（8）, formaldehyde absorbing tower
（8）Bottom and methyl alcohol vaporizing device（5）Bottom be connected, formaldehyde absorbing tower（8）Tower top and booster fan（2）Outlet is connected
Connect, formaldehyde absorbing tower（8）ECS exhaust treatment systems are set afterwards（11）, ECS exhaust treatment systems（11）Top and formaldehyde absorption
Tower（8）Top be connected, formaldehyde absorbing tower（8）Middle and lower part is connected with formaldehyde circulating pump in turn（10）With circulation formaldehyde heat exchange
Device, formaldehyde absorbing tower（8）Bottom is connected with product extraction pump.
Described ferrum molybdenum formaldehyde production technology, is filled with the iron-molybdic catalyst of production domesticization in its formaldehyde reactor.
Described ferrum molybdenum formaldehyde production technology, is filled with platinum Al catalysts in its ECS exhaust treatment system.
Advantage of the present utility model：This utility model is safe and reliable, is applicable to all iron-molybdic catalysts, including production domesticization
Iron-molybdic catalyst.
Domestic catalyst is in Xinjiang Tianzhi Chenye Chemical Industry Co., Ltd.'s one phase, 80,000 ton/year of 37% formaldehyde plant test run at present
OK.During normal operation, in product, indices see the table below：
Formaldehyde catalyst of this utility model using production domesticization, only fundamentally solves catalyst present in ferrum molybdenum method
The problem of energy import；Formaldehyde catalyst production domesticization is realized, and imported catalyst is revolutionized to domestic formaldehyde catalyst market
Monopolization.While product quality is ensured, delivery cycle is shortened, production cost is reduced, with good economic benefit
And social benefit.Formaldehyde Production field is can be widely applied to, is especially used in ferrum molybdenum formaldehyde production technology.
