Abstract
The utility model discloses the emergency set in a kind of glyoxalic acid production process, it belongs to chemical industry equipment and safety production technique field, including 1 high-order water storing tank, 1 elevated tank with caustic soda liquid, 1 emergent tail gas absorber, remaining exhaust pipe, absorption liquid storage tank and 2 emergent switch valves.Emergency set in a kind of glyoxalic acid production process disclosed in this utility model; it can be after having a power failure suddenly; maintain cooling and the tail gas absorption of reactor; the unordered discharge that the reactor temperature caused because having a power failure suddenly rises too fast and tail gas is avoided, highly beneficial to safety in production and environmental conservation.
Description
Technical field
This utility model belongs to chemical industry equipment and safety production technique field, in more particularly to a kind of glyoxalic acid production process
Emergency set.
Background technology
Glyoxalic acid is important fine chemical material, is widely used in the industries such as spice, pharmacy, pesticide, chemical industry.At present,
The country is Biformyl nitric acid oxidation method using widest production technology.
The chemical equation of Biformyl nitric acid oxidation method synthesizing glyoxalic acid is mainly shown as following 2
3CHO-CHO +2HNO3 → 3CHO-COOH+2NO ↑ +H2O
3CHO-COOH+2HNO3 → 3HOOC-COOH+2NO ↑+H2O.
The characteristics of above-mentioned 2 reaction, is：All it is strong exothermal reaction, while reaction, produces and release substantial amounts of nitrogen dioxide
Gas.Very high requirement is proposed to the temperature control and tail gas absorption of course of reaction thus.
When occurring the emergency having a power failure suddenly in production process, if just too late in the reactor cooling of Deca nitric acid
When, just occur that temperature steeply rises, or even the security incidents such as slug, excessive pot occur.If cooling is not in time, reaction can not be whole
Only, the nitrogen dioxide gas that there is also a large amount of redness enter air, and it is unfavorable that environment is brought.
For problem described above, we research and develop and assemble the emergency set in a kind of glyoxalic acid production process.
Content of the invention
The utility model discloses the emergency set in a kind of glyoxalic acid production process, it includes, high-order water storing tank, liquid caustic soda

Emergency set in a kind of glyoxalic acid production process disclosed in this utility model, in the urgent feelings for running into unexpected power failure
During condition, reactor can be implemented effectively to lower the temperature, and sufficiently effective absorption can be carried out to remaining tail gas.
Emergency set in a kind of glyoxalic acid production process disclosed in this utility model, with reasonable in design, makes simply,
Easy to operate the characteristics of.
Emergency set in a kind of glyoxalic acid production process disclosed in this utility model, is ensureing that safety in production and protection are big
Compression ring has a significant effect in terms of border.
Preferably, the high-order water storing tank described in the emergency set in a kind of glyoxalic acid production process disclosed in this utility model
For carbon steel, fiberglass or PP materials, volume is 3-5m3.
Preferably, the elevated tank with caustic soda liquid described in the emergency set in a kind of glyoxalic acid production process disclosed in this utility model
For PP or carbon steel material, volume is 2-5m3.
Emergent tail gas absorber described in a kind of emergency set in glyoxalic acid production process as claimed in claim 1
For tower plate structure, PP materials, leave unused at ordinary times, special when meeting an urgent need.
Absorption liquid storage tank described in a kind of emergency set in glyoxalic acid production process is glass as claimed in claim 1
Glass steel matter, volume is 3-5m3.
Description of the drawings
In order to be illustrated more clearly that technical scheme in the embodiment of the present invention or prior art, below will be to embodiment or existing
Accompanying drawing to be used needed for technology description is briefly described, it should be apparent that, drawings in the following description are only this reality
With some new embodiments, for those skilled in the art, can be attached to obtain other according to these accompanying drawings
Figure.
Figure -1 is the schematic diagram of the emergency set in a kind of glyoxalic acid production process disclosed in this utility model

Feed channel -7.
The detailed operation process of the emergency set in a kind of glyoxalic acid production process described in this specific embodiment embodiment
Be such, all of nitric acid dropping control valve and all of steam valve is first shut off when running into and having a power failure suddenly, is then cut
Cooling water control valve is changed, cooling is implemented to reactor in the standby cold water injection reacting kettle jacketing allowed in water storage head tank, with
This switches exhaust emissions valve simultaneously, allows tail gas to enter emergent tail gas absorber, opens elevated tank with caustic soda liquid control valve, allows 25-
32% liquid caustic soda gets off from emergent absorption tower top spray, implements neutralization to tail gas and absorbs, and absorbing liquid falls into absorption liquid storage tank, etc.
During incoming call, the absorbing liquid that can also be recycled is proceeded to elevated tank with caustic soda liquid standby.
Further, the water storage head tank described in this specific embodiment embodiment be carbon steel, fiberglass or PP materials,
Volume is 3-5m3.
Further, the elevated tank with caustic soda liquid described in this specific embodiment embodiment is PP or carbon steel material, and volume is 2-
5m3.
Further, the emergent tail gas absorber described in this specific embodiment embodiment is tower plate structure, PP materials, puts down
When idle, special when meeting an urgent need.
Further, the absorption liquid storage tank described in this specific embodiment embodiment is glass steel material, and volume is 3-
5m3.
Further, described in this specific embodiment embodiment.
Such device, the emergency set in a kind of glyoxalic acid production process disclosed in this utility model stop running into suddenly
During the emergency of electricity, reactor can be implemented effectively to lower the temperature, and sufficiently effective absorption can be carried out to remaining tail gas.
Emergency set in a kind of glyoxalic acid production process disclosed in this utility model, with reasonable in design, makes simply,
Easy to operate the characteristics of.
Emergency set in a kind of glyoxalic acid production process disclosed in this utility model, is ensureing that safety in production and protection are big
Compression ring has a significant effect in terms of border.
This utility model will not be limited to the embodiments shown herein, every in this utility model spirit and principle
Within, any modification, equivalent substitution and improvements that is made etc. are should be included within protection domain of the present utility model.This practicality
