Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, specifically to a high-efficiency and energy-saving steam boiler device. Background Technology
[0002] A steam boiler is a special type of equipment that heats water to generate steam through fuel combustion or other energy conversion methods. Steam boilers are widely used in industrial production and civil applications, covering food processing, textile printing and dyeing, chemical and pharmaceutical industries, building materials, energy and power, and civil heating.
[0003] After prolonged use, scale will build up inside a steam boiler. This scale hinders heat transfer, preventing heat from being effectively transferred from the flame or flue gas to the water. As a result, the boiler has to burn more fuel to maintain the same amount of steam, leading to a significant reduction in thermal efficiency and energy waste. The current solution is to regularly descale and clean the boiler, which is cumbersome and prone to incomplete cleaning. Therefore, we propose a high-efficiency and energy-saving steam boiler device. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency and energy-saving steam boiler device to solve the problem mentioned in the background art where scale inside the steam boiler leads to a significant reduction in thermal efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving steam boiler device, comprising a boiler shell, a front smoke box installed at one end of the boiler shell, and a rear smoke box installed at the other end of the boiler shell, a burner installed on the outer wall of the front smoke box, a combustion cylinder installed inside the boiler shell, and a first return smoke pipe and a second return smoke pipe respectively installed inside the boiler shell above the combustion cylinder, a steam pipe installed at the top of the boiler shell, and a steam valve installed at the connection between the steam pipe and the boiler shell, an energy-saving device installed on one side of the top of the boiler shell, a softening treatment box installed on the other side of the top of the boiler shell, an ion exchange treatment cylinder installed inside the softening treatment box, and ion exchange resin disposed inside the ion exchange treatment cylinder, a water inlet pipe installed on one side of the top of the softening treatment box, one end of the water inlet pipe communicating with the ion exchange treatment cylinder, a drain outlet provided on one side of the bottom of the ion exchange treatment cylinder, and a water guide pipe installed below the drain outlet, the water guide pipe communicating with the boiler shell.
[0006] Preferably, the outer wall of the combustion cylinder is fixed with equally spaced heat transfer fins, and the outer walls of the first and second return flue pipes are respectively fixed with equally spaced first and second heat-conducting plates.
[0007] Preferably, a manifold is installed at one end of the ion exchange treatment cylinder, and the connection between the manifold and the ion exchange treatment cylinder is provided with equally spaced flushing holes.
[0008] Preferably, a flushing pump is installed on one side of the top of the softening treatment tank, and a flushing pipe is installed at the output end of the flushing pump, and one end of the flushing pipe is connected to the manifold through a flushing valve.
[0009] Preferably, a storage tank is installed at the top of the softening treatment tank on one side of the flushing pump, and the storage tank is filled with saturated brine.
[0010] Preferably, a liquid filling pipe is installed on the outer wall of the bottom of the storage tank, and a liquid filling valve is installed at the connection between the liquid filling pipe and the storage tank. The bottom end of the liquid filling pipe is connected to the ion exchange treatment cylinder.
[0011] Preferably, a drain pipe is installed on the outer wall at the bottom of the ion exchange treatment cylinder, and one end of the drain pipe is connected to the ion exchange treatment cylinder through a drain valve, while the other end of the drain pipe extends to the outside of the softening treatment box.
[0012] Preferably, a filter plate is installed inside the drain outlet. The filter plate is a corrosion-resistant stainless steel mesh, which facilitates the interception of ion exchange resin.
[0013] Compared with the prior art, the beneficial effects of this utility model are: Water is introduced into the ion exchange treatment tank inside the softening treatment tank through the inlet pipe. The water comes into full contact with the ion exchange resin inside the ion exchange treatment tank. The surface of the ion exchange resin carries a large number of sodium ions. When the water passes through the ion exchange resin, the calcium and magnesium ions in the water are intercepted by the ion exchange resin and replaced by sodium ions, thus softening the hard water. By replacing the calcium and magnesium ions in the hard water with sodium ions, the scale formation is prevented through pre-softening water treatment, thereby improving thermal efficiency and saving fuel. The treated soft water enters the water guide pipe from the drain outlet and then enters the boiler body. By setting heat transfer fins on the outer wall of the combustion chamber and setting first and second heat conduction plates on the outer walls of the first and second return flue pipes, the heat exchange area is increased and heat transfer is accelerated. The flushing pump pumps water through the flushing pipe into the manifold, and the flushing holes evenly distribute the water into the ion exchange treatment cylinder to backwash the ion exchange resin. The drain valve is opened to allow the dirt to be discharged from the drain pipe, and then the liquid filling valve is opened to allow the saturated brine in the storage tank to flow into the ion exchange treatment cylinder through the liquid filling pipe to soak the ion exchange resin. After one soaking treatment, the ion exchange resin is flushed again to remove the residual brine, so that the ion exchange resin can be used to treat hard water repeatedly.

The water comes into full contact with the ion exchange resin 15 inside the ion exchange treatment cylinder 14. The surface of the ion exchange resin 15 carries a large number of sodium ions. When the water passes through the ion exchange resin 15, the calcium and magnesium ions in the water are intercepted by the ion exchange resin 15, and the sodium ions are replaced in the water, thus softening the hard water. By replacing the calcium and magnesium ions in the hard water with sodium ions, the pre-softening water treatment prevents scale formation, thereby improving thermal efficiency and saving fuel. The treated soft water enters the water guide pipe 24 from the drain outlet 22 and then enters the boiler body 1.

By setting heat transfer fins 8 on the outer wall of the combustion cylinder 7, and setting first heat-conducting fins 10 and second heat-conducting fins 12 on the outer walls of the first return flue pipe 9 and the second return flue pipe 11, the heat exchange area is increased and the heat transfer is accelerated.

A filter plate 23 is installed inside the drain outlet 22. The filter plate 23 is a corrosion-resistant stainless steel filter screen.
[0019] In this embodiment, the following steps are taken: First, an external water pump draws water into the inlet pipe 13, which then guides the water into the ion exchange treatment cylinder 14 inside the softening treatment tank 3. The water comes into full contact with the ion exchange resin 15 inside the ion exchange treatment cylinder 14. The surface of the ion exchange resin 15 carries a large number of sodium ions. When the water passes through the ion exchange resin 15, the calcium and magnesium ions in the water are intercepted by the ion exchange resin 15, and the sodium ions are replaced in the water, thus softening the hard water. By replacing the calcium and magnesium ions in the hard water with sodium ions, scale formation is prevented through pre-softening water treatment, thereby improving thermal efficiency and saving fuel. The treated soft water enters the water guide pipe 24 from the drain outlet 22 and then enters the boiler body 1. Then, the burner 2 burns the fuel inside the combustion cylinder 7. The high-temperature flue gas enters the first return flue pipe 9 from the rear smoke box 102 and then enters the second return flue pipe 11 from the front smoke box 101. The high-temperature flue gas then enters the boiler body 1. The water inside the furnace cylinder 1 is heated, and the generated steam is discharged from the steam pipe 4. By setting heat transfer fins 8 on the outer wall of the combustion cylinder 7, and setting the first heat-conducting plate 10 and the second heat-conducting plate 12 on the outer wall of the first return flue pipe 9 and the second return flue pipe 11, the heat exchange area is increased and the heat transfer is accelerated.
