Background
The instant fluid hybrid heating system refers to a heating system capable of rapidly heating a low-temperature fluid flowing through a heat source to a target temperature by the heat source. In order to achieve the instant heating effect, the heat source therein needs to be powered in real time. Common heat sources include an electric heating wire, a rare earth thick film heating pipe, a quartz heating pipe and the like, and when liquid passes through the heat sources, the liquid is heated to a target temperature and then used; or mixing the liquid with a specific liquid, and heating the mixture by a heat source to obtain the liquid with the temperature higher than the specific temperature.
However, when the current fluid mixing heating system heats a liquid containing solids, the surface of a heat source or other heating devices is easily scaled due to the over-high temperature of the heat source, so that the conduction temperature of the heat source or other heating devices cannot reach a preset value, and the scaling substances easily cause the pollution of the liquid and materials. Specifically, when the scaled fluid mixing and heating system is used to separately heat water and then mix the water with the raw material, especially when the raw material is a refrigerated low-temperature liquid, a mixed liquid having a higher temperature than that of the separately heated water cannot be obtained, and bacteria are easily mixed in the mixed liquid.
Meanwhile, when the current fluid mixing system realizes multi-stage heating, the heating device must supply energy in the heating process, and when the energy supply source is electric power, the load pressure during the multi-stage heating can cause the increase of the electricity utilization pressure and the risk.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be constructed and operated in a particular orientation and thus are not to be considered limiting.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
The scheme provides an instant heating type fluid mixing and heating system and a fluid mixing and heating method. Different from the traditional heat source heating mode, the liquid is heated by the hot steam at the position far away from the heating element, and the liquid with solid can be prevented from scaling on the surface of the heating element by the mode, so that the temperature accuracy of the subsequent liquid heating at each time is ensured. In addition, the scheme can be combined with a heater to carry out secondary heating on the liquid in the micro-pipeline, and the instant heating of the fluid containing high solid matters and having flexible and long service life is realized in a low-cost mode.
Specifically, the instant heating type fluid mixing and heating system provided by the scheme at least comprises: a conveying pipeline 10, a steam generator 30 and a feed liquid conveying interface 50, wherein a steam outlet of the steam generator 30 is connected to one end of the conveying pipeline 10 close to the liquid outlet 12 through a second steam dispersion valve 42, and a second cut-off valve 32 is arranged between the steam generator 30 and the second steam dispersion valve 41. Correspondingly, after the liquid enters the conveying pipeline 10 from the conveying pipeline 10 and/or the feed liquid conveying interface 50, the liquid is heated by the high-temperature steam generated by the steam generator 30 when being output from the liquid outlet 12 of the conveying pipeline 10.
It should be noted that, when the liquid flows in the conveying pipeline 10, the temperature of the liquid is lower than the preset temperature due to various heat losses, and the heat loss in the liquid conveying process can be supplemented by the steam heating through the liquid outlet 12. In addition, when the liquid is refrigerated and then is input into the conveying pipeline 10, the temperature of the liquid is far lower than the pipeline temperature of the conveying pipeline 10, if the traditional mode of heating the hot water in the mixing pipeline is adopted, the problem that the temperature of the liquid cannot be higher than the temperature of the conveying pipeline 10 exists, and the steam of the liquid outlet 12 is heated to enable the liquid to reach the preset high temperature.
In other embodiments, the instant heating type fluid mixing and heating system further comprises a first steam valve 41, wherein the steam generator 30 is connected to one end of the delivery pipe 10 near the liquid inlet 11 through the first steam dispersion valve 41, and a first on-off valve 31 is disposed between the steam generator 30 and the first steam dispersion valve 41.
To further reduce the cost and volume of the instant heating type fluid hybrid heating system, the first steam valve 41 and the second steam valve 42 share the same steam generator 30; the hot steam generated from the steam generator 30 is introduced into the first steam valve 41 through the first on-off valve 31, and is introduced into the second steam valve 42 through the second on-off valve 32. The opening and closing of the first on-off valve 31 and the second on-off valve 32 may be controlled remotely or may be controlled manually.
The hot steam output from the first steam valve 41 can heat the liquid input into the conveying pipeline 10, and when no liquid exists in the conveying pipeline 10, the hot steam output from the first steam valve 41 can sterilize the conveying pipeline 10; when liquid exists in the conveying pipeline 10, the hot steam output from the first steam valve 41 can play a role of pushing the liquid. To achieve the pushing effect, the first steam valve 41 is disposed near the liquid inlet 11, and the first steam valve 41 unidirectionally conveys the liquid toward the liquid outlet 12. Specifically, the first steam dispersion valve 41 is connected to a position between the feed liquid conveying interface 50 and the liquid inlet 11, and the steam in the first steam dispersion valve 41 is conveyed in a one-way direction from the first on-off valve 31 to the conveying pipeline 10.
Similarly, the hot vapor output from the second vapor valve 42 is primarily used to ultimately heat the liquid in the feed line 10, either mixed or separated, and the second vapor dispersion valve 42 is connected between the feed liquid delivery port 50 and the liquid outlet 12.
The steam in the second steam dispersion valve 42 is delivered in a unidirectional way from the second cut-off valve 32 to the delivery pipe 10. The first on-off valve 31 and the second on-off valve 32 are both one-way valves, which is beneficial to avoid the liquid in the conveying pipeline 10 from flowing backwards. Specifically, the positions of the first steam dispersion valve 41 tangent to the interior of the conveying pipeline 10 and the positions of the second steam dispersion valve 42 tangent to the interior of the conveying pipeline 10 are both provided with an opening and closing valve, and when the steam pressure is greater than the pressure in the conveying pipeline 10, the opening and closing valves are opened; when the vapor pressure is lower than the pressure in the delivery pipe 10, the opening and closing valve is closed.
In addition, the problem that the output liquid is discontinuous and even a pipe is exposed to be avoided because the delivery amount of the vapor of the hot steam is too large. The opening and closing valve forms a gap or a shrinkage cavity at the tangent position of the first steam dispersion valve 41 and the conveying pipeline 10, or the opening and closing valve forms a gap or a shrinkage cavity at the tangent position of the second steam dispersion valve 41 and the conveying pipeline 10, and the gap or the shrinkage cavity and the fluid in the conveying pipeline 10 are subjected to jet type confluence.
Specifically, the first steam distribution valve 41 sprays the steam generated by the steam generator 30 in an atomized state, and the first steam distribution valve 41 sprays the steam into the delivery pipe 10 in at least one of a reduced inner diameter spot-fire state and a gap scattering state. Similarly, the second steam distribution valve 42 sprays the steam generated by the steam generator 30 in an atomized state, and the second steam distribution valve 42 sprays the steam into the delivery pipe 10 in at least one of a spot-shot state with a reduced inner diameter and a scattered gap.
When the first steam distribution valve 41 and the second steam distribution valve 42 spray steam in a state of reducing the inner diameter point, specifically, the first steam distribution valve 41 and the second steam distribution valve 42 may be provided with at least one small hole smaller than the inner diameter of the conveying pipeline 10 at a position abutting against the inner wall of the conveying pipeline 10, so that steam is pressurized and accelerated at the small hole to be sprayed into the inner diameter of the conveying pipeline 10, and other liquid flowing with the inner diameter is dispersed and mixed under high-speed collision, and when spraying is not needed, the small hole is blocked by a needle valve which can be driven electrically or pneumatically.
When the first steam distributing valve 41 and the second steam distributing valve 42 are spraying in a manner of a gap scattering state, the first steam distributing valve 41 and the second steam distributing valve 42 may be designed to have at least one elongated gap with an opening cross-sectional area smaller than the inner diameter of the delivery pipe 10 or a circular gap abutting against the inner wall of the delivery pipe 10, and the same gap may be set to abut against the inner wall of the delivery pipe 10, so that the steam is scattered in the inner diameter of the delivery pipe 10 at the gap and mixed with other liquid flowing in the inner diameter, when scattering is not required, the small hole is blocked by a valve sheet or a sealing ring, which may be electrically or pneumatically driven, and particularly, when set as a sealing ring, the sealing ring may be a part of a one-way valve, and when the first steam distributing valve 41 and the second steam distributing valve 42 do not deliver liquid to the delivery pipe 10, the one-way valve seals the delivery pipe 10, this has the advantage that the steam is injected in a jet-type confluence manner, thereby avoiding the problem that a large amount of steam causes the blowout of the delivery pipe 10.
In addition, in order to make the liquid in the conveying pipeline 10 be conveyed towards the position of the liquid outlet 12, a control valve 21 is arranged between the liquid inlet 11 and the first vapor dispersion valve 41, the control valve 21 is selected to be at least one of an active control valve or a one-way valve, and the state of the liquid in the conveying pipeline 10 can be controlled through the control valve 21.
Specifically, when the liquid inlet 11 unidirectionally conveys liquid to the position of the conveying pipeline 10, the control valve 21 is opened, at least one of the first on-off valve 31 and the second on-off valve 32 is opened after a delay until the liquid passes through, that is, the heating type fluid mixing and heating system is in the first heating state, and at this time, the hot steam heats the liquid which enters the liquid inlet 11 alone.
When the liquid is conveyed to the position of the conveying pipeline 10 in a one-way mode by the liquid conveying interface 50, the control valve 21 is closed, the second on-off valve 32 is delayed until the liquid passes through, that is, the heating type fluid mixing heating system is in the second heating state, and at the moment, the liquid entering the liquid conveying pipeline 50 is heated by the hot steam.
When the liquid inlet 11 unidirectionally conveys liquid to the position of the conveying pipeline 10, the control valve 21 is opened, when the liquid conveying interface 50 unidirectionally conveys liquid to the position of the conveying pipeline 10, the control valve 21 is closed, the second on-off valve 32 is opened after delaying the time until the liquid passes, and the mixed liquid is heated by the hot steam output by the second steam valve 42.
When the liquid inlet 11 unidirectionally conveys liquid to the position of the conveying pipeline 10, the control valve 21 is opened, the first on-off valve 31 is opened when the liquid passes through the first on-off valve, and the liquid entering the liquid inlet 11 is heated; when the feed liquid conveying interface 50 conveys liquid to the position of the conveying pipeline 10 in a one-way mode, the control valve 21 is closed, the second on-off valve 32 is delayed to be opened when the liquid passes through, and the hot steam output by the second steam valve 42 carries out secondary heating on the mixed liquid.
In addition, in some embodiments, the instant heating type fluid mixing and heating system further comprises a heater 20, and the hot steam is matched with the heater 20 for secondary heating, so that flexible and long-life heating of the fluid containing high solid content is realized in a low-cost mode. Particularly, the heater 20 is suitable for heating low-temperature liquid in severe cold regions, the heater 20 is started to heat the liquid for the first time, the steam heating is started to heat the steam for the second time, and the heater 20 and the steam generator are used in a staggered mode while the liquid with higher temperature can be obtained.
Preferably, the heater 20 is disposed on the delivery pipe 10 near the liquid inlet 11, and the heater 20 is disposed between the control valve 21 and the liquid inlet 11. At this time, the liquid inlet 11 supplies the liquid to the heater 20 to be initially heated, and the one-way supply liquid enters the supply line 10 and is linked with at least one of the first heating state and the second heating state to be heated a plurality of times.
In addition, the structure of the first steam dispersion valve and the second steam dispersion valve provided by the scheme is described as follows: the steam dispersion valve at least comprises a valve body and a valve core arranged in the valve body, wherein the valve body at least comprises a connecting pipeline and an air inlet pipeline which are communicated with each other through pipelines, the valve core is arranged in the air inlet pipeline, and two end sides of the connecting pipeline are respectively connected with a conveying pipeline. When steam is close to the valve core, the steam dispersion valve is in an open state, and part of the valve core is exposed in the connecting pipeline; when no steam passes through the steam dispersion port, the steam dispersion valve is in a closed state, and the valve core blocks the connection part of the connecting pipeline and the air inlet pipeline.
Specifically, the valve core comprises a valve core body, an elastic element and an elastic element fixing piece, wherein the elastic element fixing piece is sleeved on the valve core body and is connected with the valve core body, one end of the elastic element is connected with the elastic element fixing piece, and the other end of the elastic element is connected with the air inlet pipeline. When the steam dispersion valve is in a closed state, the elastic element is in a natural extension state, and the valve core body is arranged in the air inlet pipeline to block the connection part of the air inlet pipeline and the connecting pipeline; when the steam dispersion valve is in an opening state, the elastic element is pressed, and the elastic element fixing piece drives the valve core body to move towards the direction of the connecting pipeline, so that steam can enter the connecting pipeline.
It is worth mentioning that the valve core comprises a limiting table, wherein the limiting table is arranged at the bottom of the valve core body, the cross section area of the limiting table is not smaller than the cross section area of the channel of the air inlet pipeline, and when the elastic element is in a natural extension state, the limiting table is positioned at the intersection of the air inlet pipeline and the conveying pipeline to block the air inlet pipeline.
The bottom end of the air inlet channel is provided with a support table, one end of the elastic element is connected with the support table, the other end of the elastic element is connected with the elastic element to be fixed, a through hole is formed in the support table, the aperture of the through hole is larger than the cross-section diameter of the valve core body and smaller than the minimum diameter of the limiting table, and the valve core body penetrates through the through hole. In one embodiment of this scheme, the saddle sets up in inlet channel's inner wall bottom.
In addition, in the present aspect, the state change of the valve element changes with the change of the vapor pressure via the intake duct. Specifically, when high-pressure steam enters the air inlet pipeline, the high-pressure steam applies pressure to the valve core, when the pressure is larger than the elastic force of the elastic element, the high-pressure steam extrudes the valve core to drive the valve core to move towards the conveying pipeline, and in the descending process of the valve core, the upward elastic force of the elastic element is increased until the upward elastic force and the downward high-pressure steam pressure are offset, and the valve core stops moving. When the pressure of the high-pressure steam is relieved, namely when the high-pressure steam pressure is not applied to the valve core any more, the elastic element has a restoring force for restoring the natural state, and the elastic element applies an elastic force to the valve core body to drive the valve core to restore the closed state.
In addition, the water level, the vapor pressure, or the temperature of the steam generator 30 is in the charged state of the set target.
In another aspect, the present disclosure provides a fluid mixing and heating method for an instant fluid mixing and heating system, including the steps of: the liquid is conveyed from the feed liquid conveying interface 50 to the conveying pipeline 10 and/or the liquid is conveyed from the liquid inlet 11 to the conveying pipeline 10, the second cut-off valve 32 is opened when the liquid is delayed to pass through the second steam dispersion valve 42, the steam generated by the steam generator 30 enters the conveying pipeline 10 from the second steam dispersion valve 42, and the instant heating type fluid mixing heating system is in the second heating state.
In addition, when the liquid is unidirectionally conveyed from the liquid inlet 11 to the position of the conveying pipeline 10, the first on-off valve 31 is delayed until the liquid passes through the first steam distribution valve 41 and is opened, and the steam generated by the steam generator 30 enters the conveying pipeline 10 from the first steam distribution valve 41, that is, the heating type fluid mixing and heating system is in the first heating state.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
