Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, and in particular to a semi-horizontal fuel gas steam generator. Background Technology

[0002] A steam generator, also known as a steam heat source or boiler, is a device that produces steam and is widely used in many industries. The working principle of a steam generator mainly relies on a heat exchange process. It generates heat through a reactor power unit, in certain types of steam generators, such as nuclear steam generators, or through fuel combustion, such as gas-fired steam generators. This heat is transferred to water, causing it to evaporate and form steam. Steam generators can be classified according to fuel type, such as gas-fired steam generators, oil-fired steam generators, coal-fired steam generators, and biomass steam generators.

[0003] The flue gas generated inside the existing steam generator is directly discharged after exchanging heat with water. The flue gas cannot stay in the steam generator for a long time, resulting in low heat utilization rate of the flue gas. This leads to a low overall heat conversion rate of the device. In addition, the existing steam generator has poor safety performance and cannot adaptively adjust the internal pressure. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a semi-horizontal fuel gas steam generator to solve the problem that the flue gas generated inside the existing steam generator is directly discharged after exchanging heat with water, and the flue gas cannot stay in the steam generator for a longer time, resulting in low heat utilization rate of the flue gas, thus resulting in low overall heat conversion rate of the device. In addition, the existing steam generator has poor safety performance and cannot adaptively adjust the internal pressure.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A semi-horizontal oil / gas steam generator includes a steam generator body, inside which is a horizontal burner. A vertical evaporator is located at one end of the horizontal burner, and a condenser is located at the upper end of the horizontal burner. The condenser contains finned heat exchange tubes. A burner mounting port is located at the end of the horizontal burner furthest from the vertical evaporator. A chimney outlet is located at the upper end of the condenser. A level gauge is located on one side of the outer wall of the vertical evaporator. An explosion-proof safety port is located on the lower outer wall of the vertical evaporator. A ash removal port is located at the upper end of the vertical evaporator. A steam outlet and a safety valve are located on one side of the upper end of the vertical evaporator. A water pump is located at one end of the back of the steam generator body, and the water pump outlet is connected to a water inlet pipe.

[0008] As an improved technical solution, a control box is provided on the outer wall of the steam generator body.

[0009] As an improved technical solution, the outer wall of the steam generator body is provided with a viewing mirror located above the burner mounting port, and the viewing mirror is connected to the horizontal burner.

[0010] As an improved technical solution, the outer wall of the vertical evaporator is provided with a drain port located at the lower end of the level gauge.

[0011] As an improved technical solution, a pressure switch is provided on the upper end of the outer wall of the vertical evaporator, and a pressure gauge is connected to one side of the pressure switch.

[0012] As an improved technical solution, the vertical evaporator is provided with several sets of fire tubes in the middle, and smoke-blocking plates are fixedly inserted into the inner wall of the fire tubes.

[0013] As an improved technical solution, a temperature sensor is connected to the upper outer wall of the horizontal burner, and the end of the water inlet pipe away from the water pump is connected to the finned heat exchange tube. The finned heat exchange tube is set in a spiral shape and is evenly distributed inside the condenser.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the burner is started to ignite the interior of the horizontal burner. The flue gas generated by the ignition enters the vertical evaporator along the furnace. The setting of the smoke baffle ensures that the flue gas can stay in the fire tube for a longer time, ensuring sufficient heat exchange between the flue gas and the water droplets outside the fire tube, thereby increasing the overall heat conversion rate of the device.

[0016] 2. In this utility model, the explosion-proof safety port allows excessive pressure in the furnace of the horizontal burner to be released through the explosion-proof safety port, ensuring normal pressure in the furnace. The level gauge installed on the outer wall of the vertical evaporator can trigger an alarm when water is insufficient and can also control the water level. When the pressure inside the steam generator is too high, it can be released through the safety valve to ensure the safe operation of the steam generator. Attached Figure Description

[0030] like Figures 1-7As shown in the figure, this embodiment provides a semi-horizontal oil-gas steam generator, including a steam generator body 1, a horizontal burner 16 inside the steam generator body 1, a vertical evaporator 17 at one end of the horizontal burner 16, a condenser 21 at the upper end of the horizontal burner 16, a finned heat exchange tube 22 inside the condenser 21, a burner mounting port 4 at the end of the horizontal burner 16 away from the vertical evaporator 17, a chimney outlet 5 at the upper end of the condenser 21, a level gauge 6 on one side of the outer wall of the vertical evaporator 17, an explosion-proof safety port 8 at the lower outer wall of the vertical evaporator 17, a ash removal port 11 at the upper end of the vertical evaporator 17, a steam outlet 12 and a safety valve 13 on one side of the upper end of the vertical evaporator 17, and a water pump 14 at one end of the back of the steam generator body 1, with a water inlet pipe 15 connected to the water outlet of the water pump 14.

[0031] A control box 2 is installed on the outer wall of the steam generator body 1.

[0032] A viewing mirror 3 is provided on the outer wall of the steam generator body 1 at the upper end of the burner installation port 4. The viewing mirror 3 is connected to the horizontal burner 16.

[0033] The outer wall of the vertical evaporator 17 is provided with a drain port 7 located below the level gauge 6.

[0034] A pressure switch 9 is provided on the upper part of the outer wall of the vertical evaporator 17, and a pressure gauge 10 is connected to one side of the pressure switch 9.

[0035] The vertical evaporator 17 has several sets of fire tubes 18 in the middle, and smoke-blocking plates 19 are fixedly inserted into the inner wall of the fire tubes 18.

[0036] A temperature sensor 20 is connected to the upper outer wall of the horizontal burner 16. The end of the water inlet pipe 15 away from the water pump 14 is connected to the finned heat exchange tube 22. The finned heat exchange tube 22 is spiral-shaped and evenly distributed inside the condenser 21.

[0037] One-button start-up via control box 2 enables fully automatic operation of the internal devices of steam generator body 1. During operation, control box 2 allows switching between high and low flames on the horizontal burner 16. High flame increases the gas production rate, while low flame maintains the temperature of the furnace within the horizontal burner 16. The horizontal burner 16 employs a horizontal combustion method, providing a sufficiently large combustion space within the furnace. The vertical evaporator 17 uses a vertical heat exchange method, conforming to the upward movement of hot steam, resulting in higher heat conversion efficiency. Fire tube 18... The interior is equipped with smoke-blocking plates 19. The finned heat exchange tubes 22 can heat the water inside through the flue gas, lowering the flue gas temperature before it is discharged from the chimney outlet 5. The burner mounting port 4 can be used to install the burner. The burner is inserted into the furnace of the horizontal burner 16, and the burner is started to ignite the interior of the horizontal burner 16. The generated flue gas flows along the furnace into the vertical evaporator 17. The smoke-blocking plates 19 ensure that the flue gas can remain inside the fire tubes 18 for a longer time, guaranteeing sufficient contact between the flue gas and the water droplets outside the fire tubes 18. Heat exchange occurs, and the flue gas from the fire tube 18 then enters the condenser 21. Before the flue gas is discharged through the chimney outlet 5, it heats the water inside the finned heat exchange tube 22, which is then discharged through the chimney outlet 5. The condenser 21 serves two purposes: cooling the flue gas and heating the water entering the vertical evaporator 17, which converts the water into steam. The furnace inside the horizontal burner 16 provides a large combustion space to ensure normal combustion. The explosion-proof safety port 8 is located in the horizontal burner... When the pressure inside the furnace of the burner 16 is too high, the excessive pressure inside the furnace can be discharged through the explosion-proof safety port 8 to ensure the normal pressure inside the furnace. The level gauge 6 installed on the outer wall of the vertical evaporator 17 can alarm when there is a water shortage, and the level gauge 6 can also control the water level. When the pressure inside the steam generator body 1 is too high, it can be discharged through the safety valve 13 to ensure the safe operation of the steam generator body 1. The temperature sensor 20 installed at the upper end of the horizontal burner 16 can monitor the temperature inside the horizontal burner 16 in real time.

[0038] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
