Description

Technical Field

[0001] The invention relates to separator technology, in particular to a gas circulation system for a separator with a vortex tube structure. Background Art

[0002] At present, separators are more and more widely used in chemical, pharmaceutical, energy, environmental protection and other industries, because the mainstream separation method of separator equipment is to drive the materials to be processed through high-speed rotation of the drum and other components to form centrifugal force, so that the solids are dehydrated and the liquids are stratified and effectively collected; and the separator is not a completely airtight structure in the separation area; considering the working principle and use of the separator, its operation is bound to produce a large amount of gas exchange. Generally, the gas will be supplemented through the structural gap or the designed air supply and air intake, and the exhaust gas is often directly discharged to the outside, or collected through the induced draft mechanism. In addition, the comprehensive collection of part of the exhaust gas through the induced draft mechanism often needs to consider the additional processing cost caused by gas mixing, which leads to a significant increase in the cost of using the separator for customers, affecting the later economic benefits. Finally, the structure of the separator generally requires hydraulic and lubrication systems, and the high-temperature circulating hydraulic oil after operation often needs to replace heat in the cooler through circulating water to ensure that the operating oil temperature of the separator is relatively stable overall; obviously, the larger the amount of hydraulic oil used for separation, the higher the amount of circulating cooling water will be. The amount of industrial circulating water is generally an important engineering consumption cost for customers. Therefore, a gas circulation system for a separator with a vortex tube structure is proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems and to provide a gas circulation system for a separator with a vortex tube structure.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a gas circulation system for a separator with a vortex tube structure, comprising a separator and a gas collector connected to the separator; wherein the system also comprises a vortex tube connected to the gas collector, the high-temperature airflow outlet of the vortex tube is connected to the separator, the low-temperature airflow outlet of the vortex tube is connected to an air-cooled cooler, and a displacement air outlet connecting hose is connected between the air-cooled cooler and the separator.

[0005] Further preferably, a high-temperature gas connecting hose is connected between the high-temperature air flow outlet of the vortex tube and the separator.

[0006] Further preferably, a regulating valve is connected between the high-temperature gas flow outlet of the vortex tube and the high-temperature gas connecting hose.

[0007] Further preferably, a low-temperature gas connecting hose is connected between the low-temperature air flow outlet of the vortex tube and the air-cooled cooler.

[0008] Further preferably, an energy-absorbing and vibration-resistant flexible connection is connected between the gas collector and the vortex tube.

[0009] Further preferably, the vortex tube is provided with a nozzle connected to the energy-absorbing and vibration-resistant flexible connection and a vortex chamber connected to the nozzle.

[0010] Beneficial effects of the present invention: after the separator runs at high speed, the present invention carries the gas in the cavity to move at high speed together. The gas after continuous operation is collected by the gas collector and then introduced into the vortex tube through the energy-absorbing and vibration-resistant soft connection. Two airflows with different directions are generated by the vortex tube. The two airflows with extremely large temperature differences are discharged from both ends of the vortex tube respectively. The high-temperature airflow of the vortex tube passes through the regulating valve, and the high-temperature gas connecting hose is introduced into the separator to supplement the gas loss of the separator during high-speed operation; the low-temperature airflow outlet of the vortex tube is connected through the low-temperature gas connecting pipe, and a large amount of low-temperature gas is continuously introduced into the air-cooled cooler. The air-cooled cooler is connected to the hydraulic system of the separator, and the internal A large amount of hydraulic oil circulates in the cavity. The continuous movement of low-temperature gas takes away a large amount of heat from the hydraulic oil, ensuring the temperature of the hydraulic oil in the separator. The gas replaced by the air-cooled cooler is effectively introduced into the separator through the replacement outlet connecting hose as an internal supplement to the gas loss during high-speed operation of the separator. The gas flow is effectively balanced, and the gas flow, flow rate and temperature difference at the low-temperature and high-temperature outlets of the vortex tube are controlled by the regulating valve to ensure the balance of the overall airflow operating temperature of the separator. Such a gas circulation system for a separator with a vortex tube controls exhaust gas emissions, reduces engineering water consumption, saves customer costs and improves economic benefits.

[0020] An energy-absorbing and vibration-resistant flexible connection 9 is connected between the gas collector 2 and the vortex tube 3; the energy-absorbing and vibration-resistant flexible connection 9 mainly prevents the separator 1 from vibrating during operation or the external vortex tube 3 from being subjected to force, thereby affecting the supporting strength of the outer casing of the separator 1 and protecting the vortex tube 3 from reducing the operating stability caused by operating vibration; the function of the vortex tube 3 is to divide the introduced gas into two, into high-temperature gas and low-temperature gas; the function of the displacement gas connection hose 5 is to introduce the gas after the heat is replaced by the air-cooled cooler 4 into the separator 1 as airflow supplement.

[0021] In one embodiment, a high-temperature gas connection hose 6 is connected between the high-temperature gas flow outlet of the vortex tube 3 and the separator 1; a regulating valve 7 is connected between the high-temperature gas flow outlet of the vortex tube 3 and the high-temperature gas connection hose 6;

[0022] The regulating valve 7 is used to regulate the flow rate of the high-temperature gas generated by the vortex tube 3; the high-temperature gas connecting hose 6 is used to introduce the regulated high-temperature gas into the separator 1 as airflow supplement.

[0023] In one embodiment, a low-temperature gas connecting hose 8 is connected between the low-temperature air flow outlet of the vortex tube 3 and the air-cooled cooler 4;

[0024] The function of the low-temperature gas connecting hose 8 is to effectively connect and introduce the low-temperature gas generated by the vortex tube 3 to the air-cooled cooler 4; the function of the air-cooled cooler 4 is to replace the heat of the hydraulic oil running the separator 1 through the circulating low-temperature gas.

[0025] In one embodiment, the vortex tube 3 is provided with a nozzle 10 connected to the energy-absorbing and vibration-resistant flexible connection 9 and a vortex chamber 11 connected to the nozzle 10;

[0026] The high-speed gas entering the vortex tube 3 enters the nozzle 10, expands and accelerates to a factor in the nozzle 10, and is injected into the vortex chamber 11 from the tangential direction to form a free vortex. The rotation angular velocity of the free vortex is greater as it approaches the center. Due to the difference in angular velocity, vortex friction is generated, and then two air flows with different directions of high temperature heat (100~130℃) and low temperature (-10~-50℃) are generated. The two air flows with extremely large temperature differences are discharged from both ends of the vortex tube 3 respectively.

[0027] The working process of the present invention is as follows: the gas after the separator 1 continuously runs at a high speed passes through the gas collector 2, and the collected gas passes into the vortex tube 3 through the energy-absorbing and vibration-resistant flexible connection 9, and the high-speed gas entering the vortex tube 3 enters the nozzle 10, expands and accelerates in the nozzle 10 to a factor, and then enters the vortex chamber 11 from the tangential direction to form a free vortex. The closer to the center, the greater the rotation angular velocity of the free vortex, the greater the vortex friction due to the difference in angular velocity, and then generates two airflows in different directions of high temperature heat (100~130℃) and low temperature (-10~-50℃), and the two airflows with extremely large temperature differences are discharged from both ends of the vortex tube 3 respectively;

[0029] The low-temperature air flow outlet of the vortex tube 3 is connected to the low-temperature gas pipe, and a large amount of low-temperature gas is continuously introduced into the air-cooled cooler 4. The air-cooled cooler 4 is connected to the hydraulic system of the separator 1. A large amount of hydraulic oil circulates in its inner cavity. Through the continuous movement of the low-temperature gas, a large amount of hydraulic oil heat is taken away, thereby ensuring the hydraulic oil temperature of the separator 1;

[0030] Finally, the gas whose heat is replaced by the air-cooled cooler 4 is effectively introduced into the separator 1 through the replacement gas outlet connecting hose 5 to supplement the gas loss of the high-speed operation of the separator 1. This is the low-temperature gas circulation route of the gas generated after the operation of the separator 1 through the vortex tube 3.
