Description
Technical field
This utility model relates to a kind of hexamethylenamine and produces equipment, and specifically a kind of modified model Urotropine defoaming is anti-
Answer still, belong to hexamethylenamine and produce apparatus field.
Background technology
The production method of hexamethylenamine divides vapor phase method and liquid phase method two kinds.Vapor phase method is more advanced, and energy-saving effect is obvious, formaldehyde
Gas and ammonia enter reactor lower part by formaldehyde pipe and ammonia pipe respectively, react, after reaction when mother solution fluid-tight
The tail gas generated is extracted out by vacuum pump, is sent to tail gas boiler combustion.Reactor is in actual motion, owing to being that two kinds of gases are at liquid
Haptoreaction in body, and evacuation, have tail gas to generate, and in reactor, liquid approximation fluidized state, can cause stronger turbulent flow, nothing
Method judges the true liquid level of internal liquid by liquidometer, thus affects the production of hexamethylenamine, causes economic benefit
Decline.The China of entitled " a kind of modified model Urotropine defoaming reactor " Application No. " 201120099222.5 " is practical new
Type patent discloses a kind of Urotropine defoaming reactor, including kettle, interlayer, kettle cover, the gas phase channel that is arranged on kettle,
Inner wall of kettle is provided with a bracer, and described bracer arranges defoaming plate, and described defoaming plate is porous plate；Set on described defoaming plate
Put one layer of stainless (steel) wire.But, this apparatus structure is simple, owing to the position of defoaming plate is fixed, and therefore cannot be along with reaction liquid level
Height change and change, reduce foam removal and reaction efficiency.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of modified model Urotropine defoaming reactor, not only can
Enough effective foams removing mother solution top layer, and can effectively reduce the turbulent flow of reactant liquor, fluidized state, reaction efficiency is efficient
The best, improve response system stability and economic benefit.
The technical solution of the utility model is:
A kind of modified model Urotropine defoaming reactor, including kettle, described kettle built with reactant liquor, and with formaldehyde gas
Pipeline is connected with ammonia pipeline, and is provided with control valve；Described kettle is provided with interlayer, and upper end is provided with kettle cover, on described kettle cover
Being provided with outlet passageway, described reactant liquor is provided with buoyancy aid, and described buoyancy aid, at least provided with three, is evenly distributed on described in polygon
The surrounding of inner wall of kettle, described buoyancy aid is provided with defoaming plate, and the buoyancy of described buoyancy aid is more than the gravity of described defoaming plate, and makes
Defoaming plate swims in the surface of reactant liquor, and described defoaming plate is porous plate.The foam on reactant liquor surface reaches the position of defoaming plate,
Intercepting through defoaming plate, crush, foam volume is not further added by, thus avoids foam and be inhaled into gas phase channel.
Further, described buoyancy aid is inflatable ball or foam block etc..
Further, described formaldehyde windpipe road and ammonia pipeline are deeply to the bottom of described reactant liquor, described reactant liquor
Inside being horizontally disposed with air distribution plate, described air distribution plate is provided with some qi-emitting holes, so that reacting gas can preferably disperse to mix
Close, improve reaction efficiency.
Further, described defoaming plate arranges one layer of stainless (steel) wire, further increases foam removal effect.
Further, described formaldehyde windpipe road and the end of ammonia pipeline connect respectively porous aeration head, described
Porous aeration head is frustum, and its bottom surface is made of porous materials, and gas is dispersed into minute bubbles, makes reaction more thorough.
Further, between described buoyancy aid, connection has pitman, it is to avoid in course of reaction, position of floating body changes, shadow
Ring the floating of defoaming plate.
When formaldehyde gas and ammonia respectively enter hexamethylenamine reactor lower part, occur anti-when reactant liquor fluid-tight
Should, hexamethylenamine reactor is in actual motion, and owing to being two kinds of gas haptoreactions in a liquid, in reactor, liquid approximates
Fluidized state, can cause stronger turbulent flow, and the foam on reactant liquor surface reaches the position of defoaming plate, intercepts through defoaming plate, crushes,
Foam volume is not further added by, thus avoids foam and be inhaled into gas phase channel.
The utility model has the advantage of: be not only able to effectively remove the foam on mother solution top layer, and can effectively drop
The turbulent flow of low reaction liquid, fluidized state, reaction efficiency height is effective, improves response system stability and economic benefit.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein
It is merely to illustrate and explains this utility model, being not used to limit this utility model.
Embodiment 1
As it is shown in figure 1, a kind of modified model Urotropine defoaming reactor, including kettle 1, described kettle 1 is built with reaction
Liquid, and be connected with formaldehyde windpipe road and ammonia pipeline, and it is provided with control valve；Described kettle 1 is provided with interlayer 2, and upper end is provided with
Kettle cover 3, described kettle cover 3 is provided with outlet passageway 4, and described reactant liquor is provided with buoyancy aid 6, described buoyancy aid 6 at least provided with three, in
Polygon is evenly distributed on the surrounding of described kettle 1 inwall, and described buoyancy aid is provided with defoaming plate 5, and the buoyancy of described buoyancy aid is big
In the gravity of described defoaming plate, and making defoaming plate 5 swim in the surface of reactant liquor, described defoaming plate 5 is porous plate, in order to reach
Preferably foam removal effect, described defoaming plate 5 arranges one layer of stainless (steel) wire.The foam on reactant liquor surface reaches the position of defoaming plate 5
