Description

Technical Field

[0001] The utility model generally relates to the technical field of micro-pressure steam generators, and in particular to a steam-water separator. Background Art

[0002] Micro-pressure steam generators are commonly used equipment for commercial cooking; micro-pressure steam generators are used to boil water to produce micro-pressure steam for cooking food.

[0003] The micro-pressure steam generated by the micro-pressure steam generator will contain larger particles of water droplets, which will not only affect the cooking quality but also increase energy consumption. Utility Model Content

[0004] In view of the above problems, the present application provides a steam-water separator that can effectively separate larger water droplets in the steam output by a micro-pressure steam generator and allow the separated water to flow smoothly back to the boiler.

[0005] The utility model provides a steam-water separator, comprising:

[0006] An outer shell, the outer shell is arranged in the steam chamber of the boiler, the side walls on opposite sides of the outer shell are respectively provided with an air inlet and an air outlet, and the side wall of the steam chamber is provided with a steam pipe connected with the air outlet; along the direction from the air inlet to the air outlet, at least one first plate and a second plate are alternately arranged on the inner side wall of the outer shell, the first plate and the second plate are respectively arranged on the side walls on opposite sides of the outer shell, the lowest point of the air outlet is higher than the bottom inner side wall of the outer shell, and the air outlet is extended upward from the bottom inner side wall.

[0007] Specifically, the present application arranges an outer shell inside the steam chamber of the boiler, and arranges a first plate and a second plate inside the outer shell, the air inlet is connected to the inside of the steam chamber, and the air outlet is connected to the steam pipe. The steam generated when the boiler is working will enter the outer shell through the air inlet, and then pass through the first plate and the second plate arranged at intervals in sequence. When the steam passes through the first plate and the second plate, water droplets in the steam adhere to the first plate and the second plate. The water droplets flow to the bottom of the outer shell under the action of gravity, and then flow out from the bottom of the air inlet and directly flow into the steam chamber. The condensed water can be reused, and the dehumidified steam is discharged through the steam pipe, thereby achieving the effect of effectively separating water vapor in the steam and recycling the separated water vapor.

[0008] Furthermore, the outer shell is a rectangular structure, the outer shell is horizontally arranged on the top of the steam chamber, and along the length direction of the outer shell, the air inlet and the air outlet are arranged at two ends of the outer shell.

[0009] Furthermore, along the length direction of the outer shell, a projection of the first plate overlaps with the second plate, and adjacent first plates and second plates are arranged at intervals.

[0010] Specifically, through this arrangement, the steam flow flows from the air inlet to the air outlet and passes through the first plate and the second plate in sequence to generate an S-shaped airflow. The S-shaped airflow will change direction multiple times, so that the airflow can better contact the surface of the plate body, thereby better allowing the water droplets to adhere to the surface of the plate body and achieving a better dehumidification effect. The S-shaped airflow can also reduce the flow rate of the airflow, thereby avoiding the airflow speed being too fast and carrying away the water droplets adhered to the plate body, thereby ensuring the dehumidification effect.

[0011] Further, along the length direction of the outer shell, a first projection of the first plate at one end of the outer shell where the air inlet is provided covers the air inlet.

[0012] Specifically, through this arrangement, it can be ensured that the airflow entering the outer shell from the air inlet will impact and contact the first plate close to the air inlet, thereby ensuring that the first plate can better adhere to water droplets and ensure the dehumidification effect.

[0013] Furthermore, a water baffle is provided in the steam chamber below the outer shell.

[0014] Specifically, by providing a water baffle, the boiling water below can be prevented from directly contacting the outer shell, and boiling water can be prevented from entering the outer shell through the air inlet, thereby ensuring the dehumidification effect and ensuring that the dehumidified water can flow out of the outer shell through the air inlet.

[0015] Furthermore, the water baffle is arranged obliquely, and the lower end of the water baffle is bent vertically downward to form a bending portion, the bending portion is spaced apart from the inner wall of the steam chamber, and the outer shell is arranged directly above the bending portion.

[0016] Specifically, by setting a bending portion at the lower end of the water baffle, when water is set in the steam chamber, the water surface partially submerges the bending portion, and the bending portion shields the water, thereby further reducing the amplitude of the water boiling and rolling upward, thereby better protecting the outer shell.

[0017] Furthermore, the boiler includes a furnace and a flame exhaust gas collecting chamber arranged below the steam chamber, a U-shaped heat pipe is arranged in the steam chamber, the U-shaped heat pipe includes a first end connected to the furnace and a second end connected to the flame exhaust gas collecting chamber, the upper end of the water baffle is located directly above the first end, and the lower end of the water baffle is located directly above the second end.

[0018] Specifically, when the boiler is heated, the gas burns in the furnace to generate a flame, and an exhaust fan is connected to the flame exhaust gas collecting chamber, thereby generating a negative pressure in the flame exhaust gas collecting chamber, so that the flame can enter the flame exhaust gas collecting chamber from the steam chamber through the inside of the U-shaped heat pipe, and the water is heated by the U-shaped heat pipe. The temperature of the first end of the U-shaped heat pipe connected to the steam chamber is higher than the temperature of the second end. Therefore, the water near the first end is heated and boiled more obviously. By setting the upper end of the water baffle just above the first end, a better shielding effect on the water can be achieved.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] The utility model provides a steam-water separator, as a specific implementation method, referring to Figure 1-Figure 6 , which includes:

[0032] An outer shell 1 is arranged inside a steam chamber 21 of a boiler 2, an air inlet 10 and an air outlet 11 are respectively arranged on the side walls on opposite sides of the outer shell, and a steam pipe 12 connected to the air outlet 11 is arranged on the side wall of the steam chamber 21; along the direction from the air inlet 10 to the air outlet 11, at least one first plate 13 and a second plate 14 are alternately arranged on the inner side wall of the outer shell, the first plate and the second plate are respectively arranged on the side walls on opposite sides of the outer shell, the lowest point of the air outlet 11 is higher than the bottom inner side wall of the outer shell, and the air outlet 11 is extended upward from the bottom inner side wall.

[0033] Specifically, refer to Figure 1 , Figure 2In the prior art, some boilers are provided with a steam pump at the steam exhaust to pump the steam exhaust back into the boiler, and the steam exhaust is re-mixed with boiler water through the aeration pipe 27, which will cause the steam in the boiler to contain a lot of particles. The present application arranges an outer shell inside the steam chamber 21 of the boiler 2, and arranges a first plate and a second plate in the outer shell, the air inlet is connected with the inside of the steam chamber 21, and the air outlet is connected with the steam pipe 12. When the boiler is working, the steam generated will enter the outer shell through the air inlet, and then pass through the first plate and the second plate arranged at intervals in sequence. When the steam passes through the first plate and the second plate, the water droplets in the steam adhere to the first plate and the second plate. Under the action of gravity, the water droplets flow to the bottom of the outer shell to form a certain height of accumulated liquid 67, and then flow out from the bottom of the air inlet 10 and directly flow into the steam chamber 21. The condensed water can be reused, and the dehumidified steam is discharged by the steam pipe 12, so as to achieve the effect of effectively separating the water vapor in the steam and recycling the separated water vapor.

[0034] Specifically, refer to Figure 4 The air inlet 10 is arranged at one end of the outer shell. When the outer shell is a rectangular parallelepiped structure, the air inlet extends upward from the bottom surface of the outer shell to the top surface. This arrangement can make the size of the air inlet as large as possible, thereby increasing the flow area. Under a certain steam flow rate, the speed of the steam flowing in the outer shell can be reduced, so that the water droplets in the steam can better contact with the first plate and the second plate, and can also better avoid the water adhering to the first plate and the second plate from being blown off due to excessive airflow, so as to achieve a better dehumidification effect.

[0035] Specifically, as an implementation method, refer to Figure 5 , Figure 6 , the first plate and the second plate each include two.

[0036] Further, as a specific implementation method, refer to Figure 4 The outer shell 1 is a rectangular structure, and the outer shell is horizontally arranged at the top of the steam chamber 21. Along the length direction of the outer shell, the air inlet 10 and the air outlet are arranged at both ends of the outer shell. By setting the outer shell as a rectangular structure, it is easier to set it inside the steam chamber 21, and it is easier to set the first plate and the second plate, wherein the first plate and the second plate can be connected to the outer shell by welding.

[0037] Furthermore, along the length direction of the outer shell, the projection of the first plate 13 overlaps with the second plate 14, and the adjacent first plates and second plates are arranged at intervals.

[0038] Specifically, the specific implementation method of the projection portion of the first plate 13 overlapping the second plate 14 is as follows: Figure 5As shown, through this arrangement, the steam flow flows from the air inlet to the air outlet and passes through the first plate and the second plate in sequence to generate an S-shaped airflow 66. The S-shaped airflow will change direction multiple times, so that the airflow can better contact the surface of the plate body, thereby better allowing the water droplets to adhere to the surface of the plate body and achieving a better dehumidification effect. The S-shaped airflow can also reduce the flow rate of the airflow, thereby preventing the airflow from being too fast and carrying away the water droplets adhered to the plate body, thereby ensuring the dehumidification effect.

[0039] Furthermore, in order to reduce the flow velocity of the airflow in the outer shell, the air inlet 10 is set to be large enough, and the air inlet extends from the bottom to the top of the outer shell.

[0040] Further, along the length direction of the outer shell, a first projection of the first plate at one end of the outer shell where the air inlet 10 is provided covers the air inlet 10 .

[0041] Specifically, through this arrangement, it can be ensured that the airflow entering the outer shell from the air inlet 10 will impact and contact the first plate close to the air inlet, thereby ensuring that the first plate can better adhere to water droplets and ensure the dehumidification effect.

[0042] Further, as a specific implementation method, refer to Figure 2 A water baffle 3 is provided in the steam chamber 21 below the outer shell 1 .

[0043] Specifically, by providing a water baffle, boiling water below can be prevented from directly contacting the outer shell, and boiling water can be prevented from entering the outer shell through the air inlet 10, thereby ensuring the dehumidification effect and ensuring that the dehumidified water can flow out of the outer shell through the air inlet 10.

[0044] Further, as a preferred embodiment, the water baffle is inclined, the lower end of the water baffle 3 is vertically bent downward to form a bending portion 31, the bending portion is spaced apart from the inner wall of the steam chamber 21, and the outer shell is arranged directly above the bending portion.

[0045] Specifically, refer to Figure 2 By setting a bending portion 31 at the lower end of the water baffle, when water is set in the steam chamber 21, the water surface 91 partially submerges the bending portion. The bending portion shields the water, thereby further reducing the amplitude of the water boiling and rolling upward, thereby better protecting the outer shell.

[0046] Further, it is understood that if the interval gap is set too narrow, the steam will quickly pass through the interval gap when the water boils, causing the water to splash, while the interval gap is too large to effectively block the boiling liquid surface. As a preferred embodiment, reference is made to Figure 2In some embodiments, the steam chamber 21 is configured as a rectangular parallelepiped structure, and a gap 32 is provided between the bending portion 31 and the side wall of the steam chamber 21. In actual use, the width of the gap is d. Figure 2 The width of the middle steam chamber 21 is D, where the value range of d is between one-fifth of D and one-quarter of D. By setting the spacing gap 32 in this way, it is possible to effectively prevent the steam from flowing rapidly in the spacing gap, effectively prevent the water from splashing under the action of steam, and effectively shield the liquid surface to achieve better protection effect.

[0047] Furthermore, the boiler 2 includes a furnace 22 and a flame exhaust gas collecting chamber 23 arranged below the steam chamber 21, a U-shaped heat pipe 24 is arranged in the steam chamber 21, and the U-shaped heat pipe 24 includes a first end connected to the furnace 22 and a second end connected to the flame exhaust gas collecting chamber 23, the upper end of the water baffle 3 is located directly above the first end, and the lower end of the water baffle is located directly above the second end.

[0048] Specifically, refer to Figure 2 When the boiler is heated, the gas burns in the furnace to generate a flame, and an exhaust fan is connected to the flame exhaust gas collecting chamber 23, so that a negative pressure can be generated in the flame exhaust gas collecting chamber, so that the flame can enter the flame exhaust gas collecting chamber 23 from the steam chamber 21 through the U-shaped heat pipe 24, and the water is heated by the U-shaped heat pipe 24. The temperature of the first end of the U-shaped heat pipe 24 connected to the steam chamber 21 is higher than the temperature of the second end, so the water near the first end is heated and boiled more obviously. By setting the upper end of the water baffle just above the first end, a better shielding effect on the water can be achieved.

[0049] Specifically, in the actual implementation process, the outer shell is arranged in the steam chamber inside the micro-pressure steam generator, and the top of the outer shell is close to the top of the steam chamber; the outer shell is a horizontally placed rectangular parallelepiped, the height of the rectangular parallelepiped is less than the distance from the highest point of the water level of the steam generator to the top of the steam chamber, the outer shell is a rectangular parallelepiped, the width of the rectangular parallelepiped is approximately less than the height of the rectangular parallelepiped, and the length of the rectangular parallelepiped is approximately three-quarters of the length of the steam chamber of the steam generator; a steam pipe for steam outlet is arranged at the upper part of one side of the long direction of the outer shell, and the steam pipe passes through the steam generator shell to deliver the steam to the steamer; a vertical rectangular opening biased to one side is provided on the other side of the long direction of the outer shell, the opening extends from the top of the outer shell to the bottom of the outer shell, and the width of the opening is approximately one-third of the width of the shell; more than two first plates and second plates are vertically arranged in the longitudinal direction inside the outer shell, the width of the first plate and the second plate is approximately two-thirds of the width of the shell, and the height is the same as the inner height of the outer shell, the first plate and the second plate are equidistantly staggered and arranged against the opposite wall, and the three sides of the first plate and the second plate are tightly connected with the three sides inside the outer shell to prevent air leakage.

[0050] In order to prevent too many large particles of water droplets from entering the steam-water separator, a water baffle is arranged in the steam chamber inside the micro-pressure steam generator. The water baffle is arranged below the outer shell. The length of the water baffle is the same as the width of the steam chamber. The water baffle is obliquely arranged in the micro-pressure steam generator. The long sides of the water baffle are connected to the steam chamber, and the wide sides. One of the short sides of the water baffle is obliquely inserted below the water level below the outer shell and its edge is only about 10 to 20 mm away from the wall of the steam chamber. The other side is raised high and the distance between its edge and the top of the steam chamber and the other wall is about 60 mm or more.

[0051] The working process of the utility model is as follows: the water in the steam generator boils after being heated, and under the action of the water baffle, the boiling water moves along the oblique direction of the water baffle in the direction away from the outer shell, and then sinks in the water pot to form an annular water flow, and the steam flows into the steam chamber calmly from the large gap above the side raised by the water baffle, which greatly reduces the water droplets brought out by the steam; the steam in the steam chamber enters the outer shell from the rectangular opening at one end of the outer shell, and the first plate and the second plate staggered in the outer shell block the steam flow from making an S-shaped movement to form a large number of floccules, which increases the chance of larger water droplets in the steam colliding with the baffle and the outer shell wall. After the water droplets collide with the baffle and the outer shell wall, they will adhere to them and flow downward, and after the water is concentrated at the bottom of the outer shell, it will flow back to the steam generator water pot in an S-shaped reverse direction along the gaps between the baffles under the action of gravity.

[0052] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
