Description

Technical Field

[0001] The utility model belongs to the technical field of ammonia-liquid separators, and specifically relates to an ammonia-liquid separator. Background Art

[0002] In many industrial fields such as chemical industry and refrigeration, the ammonia liquid separator plays an indispensable role. It is mainly responsible for fine gas-liquid separation of the gas after the ammonia liquid evaporates, ensuring that only pure ammonia enters the next process, such as the compression link of the screw compressor. In this process, the ammonia liquid separator plays a key role. It can effectively separate the ammonia liquid component in the evaporation gas of the evaporator, prevent the ammonia liquid from entering the compressor, thereby preventing the occurrence of wet stroke and liquid hammer, and ensuring the stable operation of the compressor and the continuity of the entire process.

[0003] However, traditional ammonia-liquid separators often face many challenges in the gas treatment process. Traditional separation methods, such as gravity separation or centrifugal separation, can achieve gas-liquid separation to a certain extent, but the separation effect of these methods is often unsatisfactory due to the large number of tiny droplets that may be contained in the gas. Although the gravity separation method is simple, the separation effect is limited and the separation speed is slow; while the centrifugal separation method requires a complex structure and high-speed rotating parts, which not only increases the manufacturing cost of the equipment, but also increases the difficulty of maintenance.

[0004] In addition, the traditional ammonia liquid separator also has many deficiencies in structural design. The complex structure not only increases the difficulty of manufacturing and installation, but also makes the commissioning and subsequent maintenance of the equipment cumbersome. This complexity not only increases the manufacturing cost of the equipment, but may also affect the performance stability of the separator, increase the probability of failure, and pose a threat to the continuity and safety of the entire process.

[0005] In order to solve the above problems, we proposed a new type of ammonia-liquid separator. This device achieves more efficient gas-liquid separation by optimizing the gas flow path and increasing the gas-liquid separation effect. At the same time, its structure is simple and compact, which is easy to manufacture, install and maintain. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of ammonia liquid separator. The device achieves more efficient gas-liquid separation by optimizing the gas flow path and increasing the gas-liquid separation effect. At the same time, its structure is simple and compact, and it is easy to manufacture, install and maintain.

[0007] The technical solutions adopted in this utility are as follows:

[0008] An ammonia-liquid separator comprises a shell, both sides of which are provided with end caps, an air inlet pipe for allowing gas evaporated by an evaporator to enter and an exhaust pipe for exhausting the gas are provided on the shell, a first hollow cylinder connected to the inner wall of the shell is provided at the position of the air inlet of the air inlet pipe, a plurality of first air guide plates are provided on the inner wall of the first hollow cylinder, every two of the first air guide plates are arranged alternately, and the distance between the plurality of first air guide plates increases successively from top to bottom;

[0009] A second hollow cylinder connected to the inner wall of the shell is arranged at the air inlet position of the exhaust pipe, a fixed disk is fixedly arranged inside the second hollow cylinder, a first through hole for gas discharge is opened on the fixed disk, and a rotating shaft is rotatably arranged at the bottom of the fixed disk, a first conical disk and a second conical disk are sleeved on the rotating shaft, a second through hole for gas discharge is opened on the first conical disk and the second conical disk, and a fan blade with an inclined angle is arranged at the bottom of the rotating shaft.

[0010] Furthermore, a liquid level gauge is provided on the sealing head, and a connecting port of the liquid level gauge is connected to the shell.

[0011] Furthermore, a plurality of partitions are arranged inside the shell, and every two of the partitions are arranged alternately with each other, and the distance between the plurality of partitions increases successively from left to right, and a plurality of second air guide plates are arranged between every two of the partitions, and the distance between the plurality of second air guide plates increases successively from top to bottom.

[0012] Furthermore, the first air guide plate and the second air guide plate are both provided with inclined surfaces.

[0013] Furthermore, a plurality of drain pipes are provided at the bottom of the shell.

[0014] Furthermore, a sealing cover is provided on the liquid discharge pipe.

[0015] The technical effects achieved by this utility model are:

[0016] First, the evaporator evaporates the ammonia liquid to make it a gas mixed with water vapor and ammonia gas. The fan on the evaporator allows this type of gas to enter the first hollow cylinder through the air inlet pipe. The gas hits the first air guide plate to increase its flow area, thereby increasing its condensation effect. At the same time, since the distance between the multiple first air guides increases from top to bottom, the channel is suddenly expanded to reduce the mixed flow rate. A large amount of water in the gas forms a condensation film, which accelerates the evaporation rate of water and realizes the separation of gas and liquid. The separated liquid falls to the bottom of the shell by gravity. Then, the separated gas enters the second hollow cylinder due to the pressure of the fan. Since the fan blade has a certain inclination angle, it will cause the fan blade to rotate. When the fan blade rotates, it drives the first cone disk and the second cone disk to rotate on the fixed disk through the rotating shaft. Secondly, when the gas passes through the second through hole, the rotating first cone disk and the second cone disk gas produce a centrifugal effect, so that the liquid in the gas is thrown out of the airflow under the action of centrifugal force, thereby realizing gas-solid or gas-liquid separation, and the separated liquid falls to the bottom of the shell by gravity. The device can improve the effect of ammonia liquid gas-liquid separation and has a simple structure and is easy to maintain later. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4As shown, the technical solution adopted by the utility model is specifically as follows: an ammonia-liquid separator, comprising a shell 1, a head 2 is arranged on both sides of the shell 1, an air inlet pipe 3 for the gas evaporated by the evaporator to enter, and an exhaust pipe 4 for the gas to be discharged are arranged on the shell 1, a first hollow cylinder 5 connected to the inner wall of the shell 1 is arranged at the position of the air inlet of the air inlet pipe 3, and a plurality of first air guide plates 6 are arranged on the inner wall of the first hollow cylinder 5, and every two first air guide plates 6 are arranged alternately, and the distance between the plurality of first air guide plates 6 increases from top to bottom in sequence;

[0025] A second hollow cylinder 7 connected to the inner wall of the shell 1 is provided at the air inlet position of the exhaust pipe 4, a fixed disk 8 is fixedly arranged inside the second hollow cylinder 7, a first through hole 9 for gas discharge is opened on the fixed disk 8, and a rotating shaft 10 is rotatably arranged at the bottom of the fixed disk 8, a first conical disk 11 and a second conical disk 12 are sleeved on the rotating shaft 10, a second through hole 13 for gas discharge is opened on the first conical disk 11 and the second conical disk 12, and a fan blade 14 with an inclined angle is arranged at the bottom of the rotating shaft 10.

[0026] Its working principle is as follows: first, the evaporator evaporates the ammonia liquid to make it become a gas mixed with water vapor and ammonia gas. The fan on the evaporator allows this type of gas to enter the first hollow cylinder 5 through the air inlet pipe 3. The gas hits the first air guide plate 6 to increase its flow area, thereby increasing its condensation effect. At the same time, since the distance between the multiple first air guide pipes increases from top to bottom, the sudden expansion of the channel reduces the mixed flow rate. A large amount of water in the gas forms a condensation film, which accelerates the evaporation rate of the water and realizes the separation of gas and liquid. The separated liquid falls into the shell by gravity. 1, and then the separated gas enters the second hollow cylinder 7 due to the effect of the fan pressure. Since the fan blade 14 has a certain inclination angle, the fan blade 14 will rotate. When the fan blade 14 rotates, it drives the first cone disk 11 and the second cone disk 12 to rotate on the fixed disk 8 through the rotating shaft 10. Secondly, when the gas passes through the second through hole 13, the rotating first cone disk 11 and the second cone disk 12 produce a centrifugal effect, so that the liquid in the gas is thrown out of the airflow under the action of centrifugal force, thereby realizing gas-solid or gas-liquid separation, and the separated liquid falls to the bottom of the shell 1 by gravity. The device can improve the effect of ammonia liquid gas-liquid separation, and at the same time, the structure is simple and convenient for subsequent maintenance.

[0027] Among them, a liquid level gauge 15 is provided on the end cap 2, and the connection port of the liquid level gauge 15 is connected to the shell 1. Through the liquid level gauge 15, the operator can observe the liquid level of the ammonia liquid inside the shell 1 in real time and intuitively. This helps to ensure that the amount of ammonia liquid is always maintained at an appropriate level, avoiding affecting the normal operation of the equipment due to too high or too low liquid level.

[0028] At the same time, a plurality of partitions 16 are arranged inside the shell 1, and every two partitions 16 are arranged alternately, and the distance between the plurality of partitions 16 increases successively from left to right, and a plurality of second air guide plates 17 are arranged between every two partitions 16, and the distance between the plurality of second air guide plates 17 increases successively from top to bottom.

[0029] By setting a plurality of partitions 16, the flow area can be increased, thereby increasing the condensation effect. At the same time, as the distance between the plurality of partitions 16 increases from left to right, the channel is suddenly expanded to reduce the mixed flow rate, and a large amount of moisture in the gas forms a condensation film, thereby accelerating the evaporation rate of moisture and achieving the separation of gas and liquid. By setting a plurality of second air guide plates 17, the flow area can be increased, thereby increasing the condensation effect. As the distance between the plurality of second air guide pipes increases from top to bottom, the channel is suddenly expanded to reduce the mixed flow rate, and a large amount of moisture in the gas forms a condensation film, thereby accelerating the evaporation rate of moisture and achieving the separation of gas and liquid.

[0030] Wherein, both the first air guide plate 6 and the second air guide plate 17 are provided with inclined surfaces, such a configuration can enable the condensed ammonia liquid to flow out quickly.

[0031] A plurality of drain pipes 18 are provided at the bottom of the shell 1 , through which the condensed ammonia liquid can be discharged.

[0032] It should be noted that: Figure 1 As shown, the arrangement of the drain pipe 18 can correspond to the discharge of the liquid in each step.

[0033] A sealing cover is provided on the liquid discharge pipe 18, and the liquid discharge pipe 18 is opened and closed by the sealing cover.

[0034] The working principle of the utility model is as follows: firstly, the evaporator evaporates the ammonia liquid to make it become a gas mixed with water vapor and ammonia gas, and the fan on the evaporator makes this gas enter the first hollow cylinder 5 through the air inlet pipe 3, and the gas hits the first air guide plate 6 to increase its flow area, thereby increasing its condensation effect. At the same time, since the distance between the multiple first air guide pipes increases from top to bottom, the sudden expansion of the channel reduces the mixed flow rate, and a large amount of water in the gas forms a condensation film, thereby accelerating the evaporation rate of the water, realizing the separation of gas and liquid, and the separated liquid falls on the first hollow cylinder 5 by gravity. The bottom of the shell 1, and then the separated gas enters the second hollow cylinder 7 due to the effect of the fan pressure. Since the fan blade 14 has a certain inclination angle, the fan blade 14 will rotate. When the fan blade 14 rotates, it drives the first cone disk 11 and the second cone disk 12 to rotate on the fixed disk 8 through the rotating shaft 10. Secondly, when the gas passes through the second through hole 13, the rotating first cone disk 11 and the second cone disk 12 produce a centrifugal effect, so that the liquid in the gas is thrown out of the airflow under the action of centrifugal force, thereby realizing gas-solid or gas-liquid separation, and the separated liquid falls to the bottom of the shell 1 by gravity. The device can improve the effect of gas-liquid separation of ammonia and liquid, and at the same time, the structure is simple and convenient for subsequent maintenance.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
