Description

Technical Field

[0001] This invention relates to the technical field of steam generators, and more specifically to a direct-flow steam generator. Background Technology

[0002] A steam generator is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to a place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace.

[0003] The State Administration for Market Regulation issued a new regulation, "TSG 11-2022," which exempts steam generators with a single geometric water volume of less than 30L from inspection. This exemption saves users a great deal of approval trouble, resulting in very strong market demand. However, the technical challenge of achieving a single geometric water volume of less than 30L and an evaporation capacity of 1T is quite difficult to overcome.

[0004] The existing technology still has the following areas for improvement: In the existing technology, steam is collected directly using tubes, which makes it easy for water vapor inside the tubes to mix with the steam, resulting in high steam water content. The water inside the tubes is in a boiling state, which leads to low tube stability. The flue gas produced after a large amount of fuel combustion is usually discharged directly, resulting in waste and increased production costs. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a direct-flow steam generator that can filter water vapor, improve the dryness of the steam, increase the stability of the tubes, reuse flue gas to heat steam, save costs, and reduce water vapor content.

[0006] The objective of this invention can be achieved through the following technical solutions: A direct-flow steam generator includes a heating component and a steam component, wherein the heating component is fixedly mounted on the steam component; The steam assembly contains multiple filter components, each comprising a filter tube and two fixing plates. The two fixing plates are respectively fixed at both ends of the filter tube. The fixing plate has multiple fixing holes, and the filter tube is fixedly provided with multiple upper filter plates and multiple lower filter plates, each of which has multiple filter holes.

[0007] Furthermore, damping sheets are sleeved on the outer sides of the plurality of upper filter sheets and the plurality of lower filter sheets.

[0008] Furthermore, the steam assembly also includes a furnace body, a bottom plate, a top cover, a separation disc, a combustion element, multiple V-shaped baffles, and multiple tubes.

Multiple tubes are fixedly disposed inside the furnace body, multiple filter components are located inside the multiple tubes, the multiple tubes are arranged in an array, the separation disc is fixedly disposed inside the furnace body, the separation disc is located between the multiple tubes and the top cover, multiple V-shaped baffles are fixedly disposed outside the tubes by multiple pressure strips, and the combustion element is located at the center of the interior of the multiple tubes.

[0009] Furthermore, the separation disc has multiple separation holes, which are narrower at the top and wider at the bottom.

[0010] Furthermore, the heating assembly includes a collection box and a heating box. The heating box has a heating chamber inside. The collection box and the top cover are connected by multiple steam collection pipes. The collection box and the heating chamber are connected by heating pipes. A steam outlet is fixedly provided on the heating chamber. The heating box and the furnace body are connected by a flue pipe. A flue outlet is fixedly provided on the heating box.

[0011] Furthermore, a fan is provided on the base plate, the fan is connected to the combustion element, and the steam outlet is connected to a steam collection box.

[0012] Furthermore, the multiple filter holes on the upper filter and the lower filter are staggered. The beneficial effects of this invention are: (1) By setting up a filter tube, two fixed plates, multiple upper filter plates and multiple lower filter plates, the technical effect that can be achieved is to filter water vapor through multiple upper filter plates and multiple lower filter plates, improve the dryness of steam, reduce the passage of water vapor through multiple staggered filter holes, prevent a large amount of water vapor from mixing into the steam, affecting the steam output, and save costs.

[0013] (2) By setting multiple damping plates, the technical effect that can be achieved is to increase the stability of the tube and prevent the tube from deflecting violently due to fuel combustion by setting multiple damping plates on multiple upper and multiple lower filter plates, thereby increasing the life of the tube.

[0014] (3) By setting up a collection box, a heating chamber and a heating box, the technical effect that can be achieved is to heat the steam in the heating chamber with flue gas in the heating box, reuse the flue gas, save costs, avoid fuel waste, reduce water vapor content and increase steam dryness.
