Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation, and particularly relates to a gas-liquid separator. Background Art

[0002] A gas-liquid separator is a device used to separate gas and liquid, and is widely used in industries such as chemical engineering, petroleum, natural gas, environmental protection, pharmaceuticals, and food. Its main function is to separate the liquid component in the mixed gas to meet the process requirements or improve the purity of the gas. When using the existing gas-liquid separator for gas-liquid separation, due to the high-speed upward flow of the gas, the amount of entrained liquid droplets is large, seriously affecting the effect and efficiency of gas-liquid separation, resulting in poor gas-liquid separation effect and low separation efficiency.

[0003] Therefore, there is an urgent need for a gas-liquid separator with high efficiency and excellent gas-liquid separation effect. Summary of the Utility Model

[0004] In order to solve the above technical problems existing in the prior art, the utility model provides a gas-liquid separator.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] The utility model provides a gas-liquid separator, which includes a housing. Inside the housing, a cyclone separation mechanism, an anti-liquid-carrying mechanism, and a demisting mechanism are sequentially arranged along the gas flow direction; a gas inlet is arranged on the side wall of the housing, the gas inlet extends into the housing, a gas outlet is arranged at the top of the housing, and a liquid outlet is arranged at the bottom of the housing; along the gas flow direction, the gas inlet is arranged between the two ends of the cyclone separation mechanism.

[0007] For the gas-liquid separator provided by the utility model, by setting the anti-liquid-carrying mechanism, after gas-liquid separation, during the upward flow of the gas, the gas flow rate is reduced, and the amount of liquid droplets entrained by the gas is reduced, which can effectively improve the gas-liquid separation efficiency and improve the gas-liquid separation effect.

[0008] On the basis of the above technical solution, the utility model can also make the following technical improvements:

[0009] Further, along the gas flow direction, the anti-liquid-carrying mechanism includes a gas diversion channel and a gas flow channel.

[0010] Further, the anti-liquid-carrying mechanism includes an annular member and a baffle plate arranged inside the annular member, and a gas flow channel is formed between the baffle plate and the annular member.

[0011] Furthermore, the liquid entrainment prevention mechanism further includes a plurality of gas diverter plates arranged at intervals in sequence. Gas diversion channels are formed between the gas diverter plates, and the gas diverter plates are arranged at one end of the baffle plate close to the cyclone separation mechanism.

[0012] The beneficial effect of adopting the above further technical solution is that: the gas separated by the cyclone separation mechanism moves upward, impacts the baffle plate of the liquid entrainment prevention mechanism and is diverted by each gas diverter plate, and then the flow rate is reduced, effectively reducing the amount of liquid droplets entrained by the high-speed gas, and then continues to move upward through the gas flow channel.

[0013] Furthermore, the included angle between each gas diverter plate and the vertical direction is 30 degrees.

[0014] The beneficial effect of adopting the above further technical solution is that: it effectively reduces the flow rate of the gas and prevents the formation of eddy currents.

[0015] Furthermore, the cyclone separation mechanism includes a connected annular positioning member and a conical cylinder body, and the conical cylinder body is arranged at one end of the annular positioning member away from the liquid entrainment prevention mechanism.

[0016] Furthermore, the conical cylinder body includes a first end portion and a second end portion, the diameter of the first end portion is larger than that of the second end portion, and the first end portion is connected to the annular positioning member.

[0017] The beneficial effect of adopting the above further technical solution is that: the gas-liquid mixed fluid entering through the inlet impacts the outer side wall of the conical cylinder body and is centrifugally separated. The liquid moves downward under the action of gravity, and the gas passes through the conical cylinder body and moves upward, thereby realizing gas-liquid separation.

[0018] Furthermore, the end of the inlet extending into the interior of the housing is an inclined mouth pipe.

[0019] The beneficial effect of adopting the above further technical solution is that: the setting of the inclined mouth pipe can increase the outlet area and play a guiding role in the flow direction of the fluid, thereby being beneficial to subsequent centrifugal separation.

[0020] Furthermore, the demisting mechanism is a wire mesh demister.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] The gas-liquid separator provided by the present invention, through the cyclone separation mechanism, liquid entrainment prevention mechanism and demisting mechanism sequentially arranged inside the housing, greatly reduces the flow rate of the gas flowing upward after gas-liquid separation, thereby reducing the amount of liquid droplets entrained by the gas, and can effectively improve the gas-liquid separation efficiency and improve the gas-liquid separation effect.

[0033] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Although the description of the present utility model will be introduced in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this implementation manner. On the contrary, the purpose of introducing the utility model in conjunction with the implementation manner is to cover other alternatives or modifications that may be extended based on the claims of the present utility model. In order to provide a deep understanding of the present utility model, many specific details will be included in the following description. The present utility model can also be implemented without these details. In addition, in order to avoid confusing or obscuring the key points of the present utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0034] See Figures 1-5, a gas-liquid separator, comprising a housing 1. Inside the housing 1, a cyclone separation mechanism 2, a liquid entrainment prevention mechanism 3 and a demisting mechanism 4 are sequentially arranged along the gas flow direction. The liquid entrainment prevention mechanism 3 is arranged between the cyclone separation mechanism 2 and the demisting mechanism 4 to reduce the gas flow rate and the amount of liquid droplets entrained by the gas. A side wall of the housing 1 is provided with an inlet 5 which extends into the housing 1. A gas outlet 6 is arranged at the top of the housing 1, and a liquid outlet 7 is arranged at the bottom of the housing 1. Along the gas flow direction, the inlet 5 is arranged between two ends of the cyclone separation mechanism 2, so that the gas-liquid mixed fluid entering through the inlet 5 collides with the outer side wall of the cyclone separation mechanism 2 to generate centrifugal separation, thereby realizing gas-liquid separation. The liquid is discharged through the liquid outlet 7 under the action of gravity.

[0035] The cyclone separation mechanism 2 includes a connected annular positioning member 21 and a conical cylinder 22. The conical cylinder 22 is arranged at an end of the annular positioning member 21 away from the liquid entrainment prevention mechanism 3. The conical cylinder 22 includes a first end 23 and a second end 24. The diameter of the first end 23 is larger than that of the second end 24. The first end 23 is connected to the annular positioning member 21. The gas-liquid mixed fluid entering through the inlet 5 collides with the outer side wall of the conical cylinder 22 and is centrifugally separated. The liquid moves downward under the action of gravity, and the gas passes through the conical cylinder 22 and moves upward, that is, it flows in through the second end 24 and flows out through the first end 23, thereby realizing gas-liquid separation.

[0036] The liquid entrainment prevention mechanism 3 includes an annular member 31 and a baffle 32 arranged inside the annular member 31. The baffle 32 is a circular baffle. The baffle 32 and the annular member 31 are connected by a connecting member 36. It also includes a plurality of gas diverter plates 35 arranged at intervals in sequence. The gas diverter plates 35 are arranged at an end of the baffle 32 close to the cyclone separation mechanism 2. A gas flow passage 33 is formed between the baffle 32 and the annular member 31, and a gas diversion passage 34 is formed between the gas diverter plates 35. Along the gas flow direction, the gas sequentially flows through the gas diversion passage 34 and the gas flow passage 33.

[0037] The included angle between each gas diverter plate 35 and the vertical direction is 30 degrees, which effectively reduces the gas flow rate and prevents the formation of vortices.

[0038] The gas after cyclone separation moves upward, impacts the baffle 32, and is diverted by each gas diverter plate 35, so that the flow rate is reduced, effectively reducing the amount of liquid droplets entrained by the high-speed gas, and then continues to move upward through the gas flow passage 33.

[0039] One end of the inlet 5 extending into the housing 1 is an inclined pipe, and the setting of the inclined pipe can increase the flow rate of the fluid entering the housing 1, thereby facilitating subsequent centrifugal separation.

[0040] The demisting mechanism 4 is a wire mesh demister. The gas flowing out through the gas flow channel 33 continues to move upward to the wire mesh demister. After being efficiently separated by the wire mesh demister, it flows out through the gas outlet 6 to complete the efficient gas-liquid separation.

[0041] The gas-liquid separator provided by the present utility model, by sequentially arranging the cyclone separation mechanism 2, the liquid entrainment prevention mechanism 3 and the demisting mechanism 4 inside the housing 1, after the gas-liquid separation, the flow rate of the upward flowing gas is greatly reduced by the action of the liquid entrainment prevention mechanism 3, thereby reducing the amount of liquid droplets entrained by the gas, effectively solving the problem that the high-speed fluid affects the gas-liquid separation effect and efficiency due to liquid entrainment into the wire mesh demister, and can effectively improve the gas-liquid separation efficiency and improve the gas-liquid separation effect.

[0042] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
