Abstract
The utility model belongs to the chemical production technical equipment field, concretely relates to high -order ammonia recovery system. Including unpowered ammonia recovery plant, high -order ammonia absorber, circulating slot, aqueous ammonia circulating pump, unpowered ammonia recovery plant is with the circulation and is connected with the side of high -order ammonia absorber, and aqueous ammonia circulating pump is connected with the top of high -order ammonia absorber, the bottom outlet pipe of high -order ammonia absorber and follow ring groove connection, the circulating slot is connected with aqueous ammonia circulating pump, the circulating slot still with the pipe connection of the gas system of blowing. The utility model discloses an advantage: it is complicated wayward with the operation to have overcome traditional gas ammonia recovering process, and manufacturing cost is high, and shortcoming such as unstability, has embodied the continuous production of this system stabilization simultaneously, requirement that stable production became more meticulous to this process flow is simple, and maneuverability is strong, is worth promoting.
Description
Technical field
The utility model belongs to chemical production technical apparatus field, is specifically related to a kind of high-order ammonia recovery system.
Background technology
Gas ammonia is the gas that a kind of white has intense stimulus.Gas ammonia, as a kind of important industrial chemicals, is widely used, and is transport and storage facility, usually the ammonia of gaseous state is obtained liquid ammonia by pressurizeing or cooling.Liquefied ammonia is industrially widely used, and has corrodibility, and easily volatilizees, so its chemical accident incidence is quite high.
There is the features such as recovering effect difference in the gas ammonia recovery process that tradition adopts, so can not meet the requirement of environment purification.
Given this kind of novel gas ammonia recovery system being provided, having great meaning for reducing environmental pollution further to enterprise's raising market competitiveness and production.
Summary of the invention
For solving the problem, the utility model provides a kind of high-order ammonia recovery system.
The utility model adopts following technical scheme: high-order ammonia recovery system, comprise unpowered ammonia recovery system, high-order ammonia absorber, circulation groove, ammonia circulation pump, unpowered ammonia recovery system is connected with circulation and with the side of high-order ammonia absorber, ammonia circulation pump is connected with the top of high-order ammonia absorber, the outlet at bottom pipe of high-order ammonia absorber is connected with circulation groove, circulation groove is connected with ammonia circulation pump, and circulation groove is also connected with the pipeline of blowing air system.
Described unpowered ammonia recovery system absorbs airtight connection with high-order ammonia.
Circulation groove is connected with blowing air system pipeline is airtight.
Advantage of the present utility model: overcome traditional gas ammonia recovery process complicated wayward with operation, production cost is high, and the shortcomings such as instability, embody this system continuous seepage stabilization, the requirement that stably manufactured becomes more meticulous, and this technical process is simple simultaneously, workable, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is system flowchart of the present utility model.
Embodiment
As shown in Figure 1, high-order ammonia recovery system, comprise unpowered ammonia recovery system, high-order ammonia absorber, circulation groove, ammonia circulation pump, unpowered ammonia recovery system is connected with the side of circulator with high-order ammonia absorber, unpowered ammonia recovery system absorbs airtight connection with high-order ammonia, and ammonia circulation pump is connected with the top of high-order ammonia absorber, and the outlet at bottom pipe of high-order ammonia absorber is connected with circulation groove, circulation groove is connected with ammonia circulation pump, and circulation groove is also connected with the pipeline closed of blowing air system.
Its working process is: the tail gas reclaimed from unpowered ammonia and circulator filler residual air enter high-order resorber from side, mix with the weak ammonia (from ammonia circulation pump) sprayed into from high-order ammonia absorber top, through high-order absorber bottom outlet pipe go downstream (ammonia in gas is absorbed by weak ammonia at this) enter ammonia circulation groove bottom, gas bubbling (ammonia is wherein absorbed further) in ammonia vessel rises, be separated the ammoniacal liquor droplet wherein carried secretly through filler foam-removing layer, be out sent to blowing air post through circulation groove upper outlet pipe.
By this system, liquefied ammonia that synthesis system is come is sent into ammonia storage tank storage, and control pressure and liquid level, again gas ammonia is delivered to recovery ammonia equipment (unpowered ammonia recovery), ammonia groove off-gas is delivered to after the recovery of recovery ammonia equipment through pressure self-adjusting valve, the ammonia gone out in ammonia recovery system tail gas (about containing the gas ammonia of about 8%) is reclaimed further, makes ammonia content wherein be down to less than 1%.
Claims (3)
1. high-order ammonia recovery system, it is characterized in that: comprise unpowered ammonia recovery system, high-order ammonia absorber, circulation groove, ammonia circulation pump, unpowered ammonia recovery system is connected with circulation and with the side of high-order ammonia absorber, ammonia circulation pump is connected with the top of high-order ammonia absorber, the outlet at bottom pipe of high-order ammonia absorber is connected with circulation groove, circulation groove is connected with ammonia circulation pump, and circulation groove is also connected with the pipeline of blowing air system.
2. high-order ammonia recovery system according to claim 1, is characterized in that: described unpowered ammonia recovery system absorbs airtight connection with high-order ammonia.
