Description

Technical Field

[0001] This utility model relates to the field of steam generating equipment technology, and in particular to a steam generator. Background Technology

[0002] A steam generator is an energy conversion device that transfers input heat energy to water, causing the water to undergo a phase change and generate steam. Its core function is to achieve efficient conversion of water into steam. It is widely used in industrial production, energy supply, and public services. It has similar functions to traditional boilers but is lighter and more modular in structure.

[0003] Some steam generators are equipped with a preheating function, and most of them use independent heat exchangers for water preheating. This type of structure requires additional installation space, and the heat exchange medium has no direct contact with the outer wall of the steam tank. The waste heat transfer path is long, the heat exchange efficiency is low, the preheated water temperature fluctuates greatly, and it is difficult to achieve precise temperature control.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a steam generator. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: A steam generator includes a base, on which a steam generating component and a pre-insulation component are disposed. A heat-conducting component is disposed outside the steam generating component, and a filter component is installed on the top of the pre-insulation component. A water inlet component is disposed on the top of the filter component. The steam generating component includes an evaporating tank, an insulation sleeve, and a steam pipe. The insulation sleeve is fitted over the outside of the evaporating tank, and the steam pipe communicates with the top of the evaporating tank.

An electric heating element for preheating the hot water source is installed inside the insulation tank. A guide pipe connected to the water pump is disposed at the bottom of the insulation tank. The water pump is connected to the top of the evaporating tank via the drainage pipe, which is located between the evaporating tank and the insulation sleeve. The heat-conducting component includes a protective sleeve and a waste heat recovery jacket. The protective sleeve is fixedly installed on the surface of the waste heat recovery jacket, and the drainage pipe is fixedly connected to the inner wall of the protective sleeve.

[0008] As a preferred embodiment of this utility model, the filter assembly includes a filter box, a first filter layer, a second filter layer, and a third filter layer. The first filter layer, the second filter layer, and the third filter layer are arranged sequentially from top to bottom inside the filter box, and the bottom end of the filter box is connected to the top of the heat preservation tank.

[0009] As a preferred embodiment of this utility model, the water inlet assembly includes a water inlet pipe and a spray plate, the water inlet pipe is connected to the spray plate, and the spray plate is connected to the top of the filter box.

[0010] As a preferred embodiment of this invention, the surface of the filter assembly is provided with a support component.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a waste heat recovery jacket and wrapping sleeve with heat-conducting components on the outside of the evaporator, combined with the arrangement of the diversion pipes. This allows for efficient recovery of the waste heat generated on the outer wall of the steam generator during operation. Combined with a pre-insulation component to preheat the makeup water, this shortens the waste heat transfer path, improves heat exchange efficiency, and ensures stable preheating water temperature. The filter component employs a three-layer filtration structure consisting of a stainless steel wedge mesh, cation exchange resin, and nanofiltration membrane.

[0021] Example

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A steam generator includes a base 1, on which a steam generating component 2 and a pre-insulation component 3 are mounted. A heat-conducting component 4 is disposed outside the steam generating component 2, and a filter component 5 is mounted on the top of the pre-insulation component 3. A water inlet component 6 is disposed on the top of the filter component 5. The steam generating component 2 includes an evaporator 21, an insulation sleeve 22, and a steam pipe 23. An electric heating element for preheating a hot water source is installed inside the insulation tank 21. The insulation sleeve 22 is fitted over the outside of the evaporator 21, and the steam pipe 23 communicates with the top of the evaporator 21. The pre-insulation component 3 includes an insulation tank 31, a guide pipe 32, a water pump 33, and a diversion pipe 34. The bottom of the insulation tank 31 is provided with a guide pipe 32 connected to the water pump 33. The water pump 33 is connected to the top of the evaporator 21 through the diversion pipe 34, which is located between the evaporator 21 and the insulation sleeve 22. Between; the heat-conducting component 4 includes a wrapping sleeve 41 and a waste heat recovery jacket 42. The wrapping sleeve 41 is fixedly installed on the surface of the waste heat recovery jacket 42. The drainage pipe 34 is fixedly connected to the inner wall of the wrapping sleeve 41. The waste heat recovery jacket 42 cooperates with the wrapping sleeve 41. Combined with the drainage pipe 34 located between the evaporator 21 and the insulation jacket 22, the waste heat of the outer wall of the evaporator 21 can be efficiently recovered, the water can be precisely preheated, the waste heat transfer path can be shortened, the heat exchange efficiency can be improved, and the preheated water temperature can be stabilized. The linkage design of the insulation tank 31, the water pump 33 and the drainage pipe 34, together with the evaporator 21 and the insulation jacket 22 of the steam generating component 2, not only ensures the continuity of steam generation, but also reduces heat loss. It effectively solves the pain points of low waste heat utilization, large preheating fluctuation and dispersed structure of traditional equipment, and significantly improves the energy efficiency and operational stability of the steam generator.

[0024] Please see Figure 4 The filter assembly 5 includes a filter box 51, a first filter layer 52, a second filter layer 53, and a third filter layer 54. The first filter layer 52, the second filter layer 53, and the third filter layer 54 are arranged sequentially from top to bottom inside the filter box 51. The bottom of the filter box 51 is connected to the top of the heat preservation tank 31. The first filter layer 52 is made of stainless steel wedge mesh, the second filter layer 53 is made of cation exchange resin, and the third filter layer 54 is made of nanofiltration membrane. The first filter layer 52, the second filter layer 53, and the third filter layer 54 can respectively achieve particulate impurity interception, calcium and magnesium ion softening, and deep interception of trace pollutants, effectively removing scaling factors and impurities in the water from the source and improving the quality of evaporated water.

[0025] Please see Figure 4The water inlet assembly 6 includes an inlet pipe 61 and a spray plate 62. The inlet pipe 61 is connected to the spray plate 62, and the spray plate 62 is connected to the top of the filter box 51. The cooperation between the inlet pipe 61 and the spray plate 62 can evenly disperse the incoming water and fully cover the surface of the first filter layer 52 in the filter box 51, avoiding the problem of excessive local filtration load caused by concentrated water flow impact. This ensures that each layer of the three-layer filtration structure can fully exert its filtration efficiency, improve the overall water purification uniformity and efficiency, and reduce the clogging of the filter layer caused by local impurities, thus extending the service life of the filter assembly 5.

[0026] Please see Figure 1 The filter assembly 5 is provided with a support assembly 7, which includes a support ring 71 and a support column 72. The support ring 71 is connected to the base 1 through the support column 72. The inner wall of the support ring 71 is fixedly connected to the bottom of the outer wall of the filter box 51. The cooperation between the support ring 71 and the support column 72 provides support for the filter box 51, which can prevent the filter assembly 5 from shifting or shaking under dynamic conditions such as water inflow impact and equipment operation vibration, thereby improving the stability of the equipment during operation.

[0027] Working principle: The base 1 provides stable support for the entire equipment. The water inlet pipe 61 of the water inlet assembly 6 delivers external water to the spray plate 62. The spray plate 62 evenly sprays the water into the filter box 51 of the filter assembly 5. The water passes sequentially through the first filter layer 52 made of stainless steel wedge mesh, the second filter layer 53 made of cation exchange resin, and the third filter layer 54 made of nanofiltration membrane. After impurity interception and scale removal, the water flows into the heat preservation tank 31 of the pre-heat preservation assembly 3. The heat preservation tank 31 has its own heating function, heating the water to the set threshold. When needed... When replenishing water to the evaporator 21, the water pump 33 draws filtered water from the insulation tank 31 through the guide pipe 32 and delivers it to the diversion pipe 34 located between the evaporator 21 and the insulation jacket 22. The diversion pipe 34 is attached to the inner wall of the wrapping sleeve 41 of the heat conduction component 4. With the help of the residual heat emitted by the evaporator 21 when the steam generating component 2 is working, the water in the diversion pipe 34 is insulated and reheated through the waste heat recovery jacket 42 and the wrapping sleeve 41. The preheated water enters the evaporator 21 and is heated and vaporized to generate steam, which is finally output for use through the steam pipe 23.
