Description

TECHNICAL FIELD

[0001] The utility model relates to vaporizer technical field especially relates to a new air bath type vaporizer structure. BACKGROUND

[0002] Air bath type vaporizer is a kind of heat exchange equipment by natural air convection heating low-temperature liquid medium. Its core principle is to utilize the heat of ambient air to vaporize low-temperature liquid medium into gas, without additional energy, belonging to energy-saving and environment-friendly vaporization device.

[0003] In the working process, since the temperature of low-temperature liquid in the vaporizer is much lower than the ambient temperature, the temperature of the front surface of the vaporizer will be reduced, and when the temperature of the front surface of the vaporizer is lower than the dew point temperature of air, the water vapor in the air will condense into frost on the front surface of the vaporizer, while the rear section of the vaporizer does not have obvious frosting phenomenon. The frosting process is usually divided into frost crystal growth period, frost layer growth period and frost layer full growth period

[0004] Its hazards mainly include: affecting heat transfer efficiency: the frost layer has a certain thermal resistance, and with the increase of the thickness of the frost layer, it will hinder the heat transfer between air and the vaporizer, reduce the heat exchange effect of the vaporizer, cause the vaporization efficiency to decrease, and the outlet temperature to fail to reach the design value, so as to fail to meet the gas demand. Increasing air flow resistance: the frost layer will adhere to the surface of the finned tube, narrow the channel between the fins, increase the air flow resistance, and reduce the air flow rate, thereby affecting the heat exchange capacity on the air side, and rapidly reducing the heat exchange capacity. Causing equipment damage: when frosting is serious, the weight of the frost layer may cause the finned tube or other parts of the vaporizer to bear additional stress, causing the equipment to deform and damage. In addition, due to the different frosting degrees of different parts, the vaporizer may also be unevenly stressed, appear lateral tension, cause pipeline rupture, gas leakage and other accidents. Affecting subsequent processes: for some production processes with strict requirements on gas temperature and pressure, the problems of air bath type vaporizer frosting, gas temperature reduction and pressure instability will affect the normal operation of subsequent processes, and even may cause product quality to decrease or production accidents.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by adding a valve, when the ambient temperature is low and the humidity is high, and it is anticipated that frosting will intensify, the operator can precisely control the valve to appropriately adjust the flow rate of the cryogenic liquid in the connecting bend. Reducing the liquid flow rate lowers the heat exchange rate between the liquid and the external environment, thereby effectively suppressing the sublimation and frosting process of water vapor. Furthermore, the addition of the valve does not merely increase operational complexity; on the contrary, it makes precise control of the vaporizer's operation possible. The operator can flexibly adjust the valve opening degree according to the actual working conditions, ensuring both efficient and stable operation of the vaporizer and cleverly avoiding the annoying frosting problem—achieving two goals at once and greatly enhancing the ability of the ambient temperature vaporizer to cope with complex environments.

[0023] 2. In this invention, a vibration defrosting mechanism uses fluid kinetic energy to drive a rotating plate to generate electricity.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0036] Refer to Figure 1-8The utility model provides an embodiment: a novel air bath type vaporizer structure, including support frame 1, the bottom of support frame 1 is installed with support leg 2, the inside of support frame 1 is installed with the star finned tube 3 of uniform distribution, a plurality of star finned tube 3's outer wall is installed with connecting frame 4, and one end of adjacent star finned tube 3 is connected through connecting bend pipe 5, and the outer wall one side of connecting bend pipe 5 is connected with the one end of liquid inlet pipe 6, and the other end of liquid inlet pipe 6 is connected with the one end of liquid inlet main pipe 7, and the other end of liquid inlet main pipe 7 is used to extract low temperature liquid, and the inside of liquid inlet pipe 6 is installed with regulating valve 8, and the inside one end of liquid inlet pipe 6 is installed with vibration defrosting mechanism 9, and it is used to remove the frost layer near regulating valve 8, and the bottom of support frame 1 is also provided with frost particle discharge mechanism 10, and it is used to discharge frost particle.

[0037] Vibration defrosting mechanism 9 includes rotating shaft 901, and the both ends of rotating shaft 901 are rotatably connected to the inner wall one side of liquid inlet pipe 6, and the outer wall of rotating shaft 901 is installed with rotating plate 902, and the outer wall one side of rotating shaft 901 is fixedly connected with permanent magnet 903, and the outer wall one side of liquid inlet pipe 6 is installed with induction coil 904, and the output end of induction coil 904 is connected with outer line 905, and one end electrically connected with electromagnetic vibrator 906 of outer line 905, and electromagnetic vibrator 906 is installed on the outer wall one side of liquid inlet pipe 6;

[0038] The surface of star finned tube 3 is processed with sharkskin microgroove 301, and the root of star finned tube 3 is welded with reinforcing rib plate 302, and the thickness of reinforcing rib plate 302 is 1.5 times of the wall thickness of star finned tube 3.

[0039] The inner wall of connecting bend pipe 5 is provided with spiral flow guide vane 501;

[0040] Specifically, when low temperature liquid starts flowing through liquid inlet pipe 6, the flow of liquid will generate impact force, which acts on rotating plate 902. Since rotating plate 902 is installed on rotating shaft 901, and the both ends of rotating shaft 901 can rotate in the inner wall of liquid inlet pipe 6, rotating plate 902 will rotate around rotating shaft 901 under the action of liquid impact force. With the rotation of rotating plate 902, the permanent magnet 903 fixedly connected therewith will also rotate synchronously. According to the principle of electromagnetic induction, the induction coil 904 in the changing magnetic field will generate induced current. Here, the rotation of permanent magnet 903 causes the periodic change of the magnetic field around it, and the induction coil 904 on the outer wall one side of liquid inlet pipe 6 is just in this changing magnetic field, thereby generating induced current. The induction coil 904 is electrically connected with electromagnetic vibrator 906 through outer line 905, and the induced current generated is transmitted to electromagnetic vibrator 906 through outer line 905, driving electromagnetic vibrator 906 to work. The high-frequency vibration generated when electromagnetic vibrator 906 works can effectively shake off the frost near regulating valve 8 caused by the temperature difference between low temperature liquid and the environment, thereby ensuring the normal operation of regulating valve 8 and the smoothness of liquid flow in liquid inlet pipe 6.

[0041] The frost particle discharging mechanism 10 comprises a collecting groove 1001, one end of the collecting groove 1001 is arranged at the outer wall of the support frame 1, an extension support 1002 is installed at the outer wall of the support frame 1, a fan 1003 is installed at the outer wall of the extension support 1002, a flow guide pipe 1004 is communicated with the input end of the fan 1003, a frost blowing pipe 1005 is communicated with the output end of the fan 1003, one end of the frost blowing pipe 1005 extends into the inside of the collecting groove 1001;

[0042] A wedge-shaped plate 1006 is installed at the outer wall of the flow guide pipe 1004, and a plurality of wedge-shaped holes 1007 are arranged on the outer wall of the wedge-shaped plate 1006;

[0043] The collecting groove 1001 is arranged obliquely, and the cross section of the collecting groove 1001 is V-shaped;

[0044] Specifically, during the operation of the vaporizer, when frost particles are generated, the fan 1003 is started. The external air first passes through the flow guide pipe 1004, and the wedge-shaped plate 1006 installed at the outer wall of the flow guide pipe 1004 and the wedge-shaped holes 1007 arranged on the outer wall of the wedge-shaped plate 1006 can pretreat the air entering the flow guide pipe 1004. The wedge-shaped plate 1006 can change the flow direction of the air, so that the air forms complex air flow disturbance around the wedge-shaped plate 1006, and the wedge-shaped holes 1007 can further split and straighten the air, so that the air entering the flow guide pipe 1004 is more uniform and stable. The pretreated air enters the fan 1003, and the fan 1003 accelerates the air through the high-speed rotating impeller, so that the air obtains a large kinetic energy. The accelerated air is blown into the obliquely arranged collecting groove 1001 with a V-shaped cross section through the frost blowing pipe 1005. The obliquely arranged collecting groove 1001 can utilize the gravity to make the frost particles more easily slide to the bottom of the collecting groove 1001. The V-shaped cross section design increases the collection area of the collecting groove 1001, and is also beneficial to the formation of special air flow circulation in the collecting groove 1001, which enhances the impact and carrying capacity of the frost particles, so as to discharge the frost particles from the support frame 1 and the vaporizer, and avoid the accumulation of the frost particles to affect the normal operation of the vaporizer.

[0045] The surface of the valve core of the regulating valve 8 is sprayed with a graphene-ceramic composite coating 801, and a temperature sensor 802 is arranged in the regulating valve 8;

[0046] Specifically, the temperature sensor 802 inside the regulating valve 8 can monitor the temperature of the low-temperature liquid flowing through the regulating valve 8 in real time. When the temperature sensor 802 detects a change in the temperature of the liquid, it will convert the temperature signal into an electrical signal and transmit it to the control system connected to it (if the control system is not mentioned, it is assumed that the operator will manually adjust according to the temperature display). The control system adjusts the opening of the regulating valve 8 according to the preset temperature range and the actual temperature signal. For example, when the temperature of the liquid is too low, the control system will control the regulating valve 8 to increase the opening, so that more low-temperature liquid enters the vaporizer to increase the vaporization amount and increase the temperature; conversely, when the temperature is too high, the opening of the regulating valve 8 is reduced. In addition, the graphene-ceramic composite coating 801 sprayed on the surface of the valve core of the regulating valve 8 has many excellent properties. Graphene has good electrical conductivity, high strength, and excellent thermal conductivity, and ceramic materials have high hardness, wear resistance, and corrosion resistance. The graphene-ceramic composite coating 801 can effectively improve the wear resistance of the valve core, because the low-temperature liquid may cause erosion and wear to the valve core when flowing through the regulating valve 8, and the graphene-ceramic composite coating 801 can greatly reduce the degree of wear and extend the service life of the regulating valve 8. At the same time, the corrosion resistance of the coating can prevent impurities or chemicals in the low-temperature liquid from corroding the valve core, ensuring that the regulating valve 8 works stably for a long time and maintains accurate regulation of the flow and temperature of the low-temperature liquid.

[0047] Working principle: Confirm that all components are installed properly, check that the regulating valve 8 is in the initial appropriate state, the temperature sensor 802 is working properly, the electrical equipment such as the fan 1003 and the electromagnetic vibrator 906 is connected correctly and has good insulation, turn on the liquid inlet pipe 7 to draw low-temperature liquid, the liquid enters the connecting elbow 5 through the liquid inlet pipe 6, and the regulating valve 8 adjusts the flow according to the demand during the process. The liquid flowing through the liquid inlet pipe 6 drives the electromagnetic vibrator 906 of the vibration defrosting mechanism 9 to vibrate and defrost around the regulating valve 8, and the low-temperature liquid flows into the star-shaped finned tube 3 through the connecting elbow 5. In the tube, the ambient air is used to vaporize, and during the vaporization process, if frost particles are generated, the fan 1003 is started, and the external air enters through the guide pipe 1004, and the air is accelerated by the fan 1003 and then blown into the inclined V-shaped collection groove 1001 through the defrosting pipe 1005, to remove the frost particles. During operation, the temperature of the liquid is monitored by the temperature sensor 802 inside the regulating valve 8, and the opening of the regulating valve 8 is adjusted according to the actual situation.

[0048] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
