The utility model embodiment provides a kind of defoaming agent dosing system, as shown in Figure 1, the defoaming agent dosing system packet
It includes: medicament device for casting 1 and medicament mixing device 2；
Medicament device for casting 1 includes the chemical tank 11 for holding defoaming agent；
Medicament mixing device 2 includes injector 21, and injector 21 includes sequentially connected collapsible tube 2101, mixing tube 2102
With diffuser 2103；Collapsible tube 2101 has the contraction structure tapered towards mixing tube 2102, and diffuser 2103 has far from mixed
Close the diffusion structure that pipe 2102 is spread；Injector 21 further includes nozzle 2104, and the outlet of nozzle 2104 is located at contraction chamber 2101
It is internal；
Chemical tank 11 is connected to collapsible tube 2101.
It is understood that medicament device for casting 1 is mixed for the filling of defoaming agent and storage, and when needed to medicament
2 quantification of device adds；Medicament mixing device 2 (can add for completing defoaming agent and solution for desulfuration solution or other needs
Add the solution of defoaming agent) be sufficiently mixed.
For being defoamed defoaming agent addition desulfuration solution, in application, as shown in Figure 1, the defoaming agent added being
System is mounted on the solution injection device 3 for injecting desulfuration solution, and solution injection device 3 includes solution mixing pump 31, solution
Pump intake pipeline 32 and solution pump outlet line 33, one end of solution pump suction line 32 can connect regenerator, solution pump discharge
Pipeline 33 can connect desulfurizing tower, that is, desulfuration solution is under the power effect of solution mixing pump 31, from regenerator through solution pump intake
Pipeline 32 enters solution pump outlet line 33, and travels further into desulfurizing tower.
Specifically, the arrival end of nozzle 2104 is connected on solution pump outlet line 33, by the outlet of diffuser 2103
End is connected on solution pump suction line 32, so that medicament mixing device 2 is formed circulation branch road on solution injection device 3, so
Setting can make original solution mixing pump 31 provide power to medicament mixing device 2, simultaneously as tap line diameter (example
Such as, nominal diameter 20mm) much smaller than the pipeline diameter (for example, nominal diameter be 200mm) of solution injection device 3, because without
Influence the normal operation of solution injection device 3.
The working principle of defoaming agent dosing system provided by the embodiment of the utility model are as follows: pumped out from solution mixing pump 31
Desulfuration solution enters collapsible tube 2101 through circulation branch road, through nozzle 2104, as the aperture interface of collapsible tube 2101 is gradually reduced,
The pressure of desulfuration solution constantly rises, and flow velocity is also continuously increased, according to Venturi effect, when desulfuration solution is from collapsible tube 2101
When ejection, negative pressuren zone can be formed at collapsible tube 2101, is connected to due to being formed by negative pressuren zone with chemical tank 11, it is adsorbable
Defoaming agent in chemical tank 11 enters diffuser 2103, and then enters in mixing tube 2102 together with desulfuration solution, and mix, and mixes
It closes sufficient mixed liquor and enters back into diffuser 2103, the outlet end through diffuser 2103 enters solution pump suction line 32, so
It is sufficiently mixed desulfuration solution before entering desulfurizing tower with defoaming agent.
Defoaming agent dosing system provided by the embodiment of the utility model includes injector by setting medicament mixing device 2
21, and injector 21 is connected to the pipeline of the chemical tank 11 of medicament device for casting 1 and solution injection device 3 respectively, can make to defoam
Agent and desulfuration solution enter injector 21, and are sufficiently mixed in injector 21, form mixed solution, and mixed solution enters back into
Desulfurizing tower.The defoaming agent dosing system enters desulfurizing tower after defoaming agent and desulfuration solution can be made to be sufficiently mixed, and gives full play to and disappears
The effect of infusion reaches better defoaming effect.
It should be noted that the defoaming agent dosing system to be mounted on to the two of the solution mixing pump 31 of solution injection device 3
Side forms circulation branch road, it is intended that solution mixing pump 31 provides power for system operation, in fact, also the defoaming agent can be made to add
The medicament mixing device 2 of system includes power device (for example, pump), in this way, the defoaming agent dosing system can be made to be mounted on solution
The two sides of any pipe string in injection device 3 between regenerator and desulfurizing tower form circulation branch road.
In addition, the defoaming agent dosing system is also not necessarily limited to be mounted on the solution pipeline for injecting desulfuration solution, may be used also
It is mounted on the solution pipeline of any required addition defoaming agent.
In above-mentioned defoaming agent dosing system, suction function that the defoaming agent in chemical tank 11 is formed in injector 21
Under be adsorbed into injector 21, that is, the filling speed of defoaming agent depend on injector 21 in vacuum magnitude, work as injector
When the negative pressure formed in 21 is too small, the filling speed of injector 21 can be made too slow, and then influence defoaming effectiveness.It, can based on this
Making medicament device for casting 1 includes the acceleration equipment for accelerating the defoaming agent injection in chemical tank 11.
Illustratively, can make medicament device for casting 1 further includes for providing injection power to the defoaming agent in chemical tank 11
Boost motor 12.
In application, defoaming agent can be accelerated in injection injector 21 under the power effect that boost motor 12 provides.
With the chemical tank 11 placed vertically, chemical tank 11 it is opening up for, wherein boost motor 12, which can be, is connected to
Pump at 11 outlet at bottom of chemical tank is also possible to that the piston-cylinder at the top of chemical tank 11 is arranged in, further, can basis
Actual needs sets power size provided by pump or piston-cylinder.
