As shown in fig. 1-5, the invention provides a foam breaker 1 for a deamination tank, which comprises a foam breaker frame 11 and a foam breaker arranged in the foam breaker frame 11, wherein the foam breaker frame 11 is arranged at a gas outlet pipeline 21 above a deamination tank 2, the foam breaker comprises a support 12, a connecting shaft 14, an impeller 15 and a rotary cutter set 16, the support 12 is fixedly connected with the inner wall of the foam breaker frame 11, a shaft sleeve is arranged in the center of the support 12, the connecting shaft 14 penetrates through the support 12 and is rotatably connected with the support 12, the arrangement direction of the connecting shaft 14 is overlapped with the axis of the gas outlet pipeline 21, the impeller 15 is arranged at the top end of the connecting shaft 14, and the rotary cutter set 16 is arranged at the bottom end of the connecting shaft 14.
The bubble breaker frame 11 is of a four-way structure, and two outlets on the side face of the bubble breaker are provided with double-scraper toughened glass viewing mirrors 13 for observing the running state of the defoaming device. Specifically, two outlets of the top surface and the bottom surface of the foam breaker frame 11 are connected with the air outlet pipeline 21, the setting direction of the connecting shaft 14 is parallel to the two outlets of the top surface and the bottom surface of the foam breaker frame 11, two outlets of the side surface of the foam breaker are provided with double-scraper toughened glass sight glasses 13, an impeller 15 and a rotary cutter group 16 of the defoaming device are within the visible range of the double-scraper toughened glass sight glasses 13, and a worker can directly observe the states of the impeller 15 and the rotary cutter group 16 through the double-scraper toughened glass sight glasses 13. The double-scraper toughened glass sight glass 13 is an existing conventional toughened glass sight glass which is arranged on one side of the pipeline and used for observing the interior of the pipeline.
In the invention, the deammoniation tank bubble breaker 1 is installed at one end of the air outlet pipe 21 close to the deammoniation tank 2, and the rotary cutter set 16 of the defoaming device is closer to the deammoniation tank 2 than the impeller 15, that is, the rotary cutter set 16 is located right below the impeller 15 in the view of fig. 1.
The working principle of the invention is as follows: when steam generated in the deamination process is discharged through the gas outlet pipeline 21, the impeller 15 is pushed to rotate, the impeller 15 is connected with the rotary cutter set 16 through the connecting shaft 14, the rotary cutter set 16 rotates along with the rotation of the impeller 15, the rotary cutter set 16 breaks bubbles contacted with the impeller, the steam in the bubbles is released and discharged, and slurry flows back to the deamination tank 2.
It should be noted that, because the foam breaker 1 of the deamination tank directly contacts with high-temperature and corrosive substances, the deamination tank cannot use a bearing, but only adopts a shaft sleeve, the shaft sleeve is made of high-temperature-resistant and corrosion-resistant materials, and the bracket 12, the connecting shaft 14, the impeller 15 and the rotary cutter set 16 are made of stainless steel materials.
Further, a blade pitch angle of the rotary cutter group 16 is smaller than a blade pitch angle of the impeller 15, and preferably, the blade pitch angle of the rotary cutter group 16 ranges from 0 to 10 °. It is easy to understand that the power source of the defoaming device is the impeller 15, and what really plays a defoaming role is the rotary cutter set 16, if the blade pitch angle of the rotary cutter set 16 is too large, the contact surface between the blade of the rotary cutter set 16 and the steam bubble becomes small. In addition, because the steam can pass through the rotary cutter set 16 first and then pass through the impeller 15, if the blade pitch angle of the rotary cutter set 16 is too large, even larger than the blade pitch angle of the impeller 15, the steam can directly drive the rotary cutter set 16 to rotate, and because the contact surface between the blade of the rotary cutter set 16 and the steam bubble becomes small, a pressure difference beneficial to extracting the steam bubble is easily formed at the rotary cutter set 16, so that the steam bubble which is not broken is directly pumped into the air outlet pipeline 21 to be discharged under the driving of the air flow, and the capacity of the deamination tank 2 is further reduced.
Therefore, the blade pitch angle of the rotary cutter set 16 of the present invention is smaller than the blade pitch angle of the impeller 15, preferably, the blade pitch angle of the rotary cutter set 16 ranges from 0 to 10 °, the blades of the rotary cutter set 16 do not rotate under the impact of the air flow, and an air pressure difference is not formed at the rotary cutter set 16, and since the blade pitch angle is smaller, the contact area between the blades and the steam bubbles is larger, which is beneficial to breaking the steam bubbles.
It should be noted that the rotation of the impeller 15 does not discharge bubbles directly but introduces bubbles
In order to better break the bubbles, the present invention provides a sharp piercing protrusion 17 for breaking bubbles on the side surface of the blade of the rotary cutter set 16 along the rotation direction of the rotary cutter set 16, as shown in fig. 1. It should be noted that fig. 4 only shows the arrangement of the blades of the rotary cutter group 16, and the piercing protrusion 17 is not shown. Specifically, taking the view of fig. 4 as an example, when the rotary cutter set 16 rotates clockwise, the spine protrusion 17 is disposed on the right side of the blade, and similarly, when the rotary cutter set 16 rotates counterclockwise, the spine protrusion 17 is disposed on the left side of the blade.
In the rotating process of the rotary cutter set 16, the sharp thorn bulge 17 on the side surface of the blade breaks the steam bubble contacted with the sharp thorn bulge, the steam in the steam bubble is released, the serous fluid in the steam bubble is contacted with the blade, in order to increase the contact area of the blade and the serous fluid, a bulge part which protrudes downwards is arranged in the blade, the serous fluid on the bottom surface of the blade is blocked by the bulge part, is accumulated at the bulge part, and is thrown out to the inner wall of the foam breaker frame 11 along the bulge part.
In the present invention, the number of the blades of the impeller 15 is greater than the number of the blades of the rotary cutter set 16, wherein the number of the blades of the rotary cutter set 16 is four, and the four blades are uniformly arranged at the bottom end of the coupling shaft 14; the number of the blades of the impeller 15 is at least more than five, preferably, the number of the blades is seven, adjacent blades are close to each other and do not overlap, and the outermost ends of the blades of the impeller 15 are close to the inner wall of the foam breaker frame 11.
It should be noted that, in the present invention, the number of the blades of the rotary cutter set 16 needs to be smaller than the number of the blades of the impeller 15, because the impeller 15 is a power source of the defoaming device, if the number of the blades of the rotary cutter set 16 is too large, that is, the total area of the blades contacting with the steam bubbles is too large, the normal discharge of the steam is affected, and further the rotation of the impeller 15 is affected, and in the case that the impeller 15 is difficult to rotate, the rotary cutter set 16 cannot break the steam bubbles.
Therefore, a sufficient space needs to be reserved between the blades of the rotary cutter set 16 of the present invention, which does not affect the normal discharge of steam, the arrangement of the blades of the present invention is as shown in fig. 4, the four blades are uniformly arranged at the bottom end of the coupling shaft 14, and the whole rotary cutter set 16 is cross-shaped. Whereas the total area of the blades of the impeller 15 is as large as possible as shown in fig. 3, so that the steam passing through the impeller 15 can drive the impeller 15 to rotate as much as possible, the blades of the impeller 15 should cover as much as possible the cross section of the bubbler frame 11 in the view of fig. 3.
The invention also provides a defoaming method, which uses the defoaming device 1 for the ammonia removal tank and comprises the following specific steps:
the bubble breaking device 1 of the ammonia removing tank is arranged on an air outlet pipeline 21 of the ammonia removing tank 2, so that the direction of a connecting shaft 14 is parallel to the gas flow direction in the air outlet pipeline 21, wherein an impeller 15 is positioned above a rotary cutter group 16, and the rotary cutter group 16 is positioned in an air outlet of the ammonia removing tank 2;
deaminating the liquid in the deamination tank 2, generating a large amount of steam when the temperature in the tank is raised to the boiling point of the liquid, gradually accumulating a large amount of bubbles on the liquid level of the liquid in the tank until the bubbles are filled in an air outlet of the deamination tank 2, and covering the rotary cutter set 16;
steam generated in the deamination process forms air flow, when the air flow is discharged along an air outlet pipeline 21, an impeller 15 of the defoaming device is pushed to rotate, torque generated by the rotation of the impeller 15 drives a rotary cutter set 16 below to rotate through a connecting shaft 14, sharp piercing bulges 17 of blades of the rotary cutter set 16 pierce bubbles, the steam in the bubbles is released and discharged along with the air flow, the impeller 15 is further pushed to rotate, and slurry carried by the bubbles is thrown to a bubble breaker frame 11 along with the centrifugal action generated by the rotation of the rotary cutter set 16 and flows back to the inside of the deamination tank 2.
According to the invention, the deammoniation tank bubble breaker 1 is arranged at the air outlet pipeline 21 of the deammoniation tank 2, steam generated in the deammoniation process is used for pushing the impeller 15 of the deammoniation tank bubble breaker 1 to rotate, so that the rotary cutter set 16 is driven to move, the rotary cutter set 16 breaks bubbles generated in the deammoniation process, the steam in the bubbles is released and discharged, slurry carried by the bubbles is thrown to the inner wall of the deammoniation tank bubble breaker 1 under the centrifugal action generated by the rotation of the rotary cutter set 16 and flows back into the deammoniation tank 2, the problem existing in the last two decades of preparing zinc oxide by an ammonia method is successfully solved, the capacity of the deammoniation tank 2 is greatly improved, and the production cost is effectively reduced.
