Description

Technical Field

[0001] This utility model relates to the field of gas-fired steam generator technology, specifically an ultra-low nitrogen through-flow gas-fired steam generator. Background Technology

[0002] A steam generator, also called a steam heat source machine, 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-containing container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace.

[0003] Existing gas-fired steam generators lack a device for adding cleaning fluid to the inside of the water tank to remove scale. This prevents the cleaning fluid from being added accurately to the water tank, affecting the scale removal effect on the steam generator pipe walls. In addition, existing steam generators lack a water source filtration device on the inlet pipe, preventing water softening and increasing the amount of scale buildup on the steam generator pipes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an ultra-low nitrogen through-flow gas steam generator. By setting up a cleaning liquid tank, a liquid pump, a suction pipe and a flow sensor, the liquid pump delivers the scale removal liquid in the cleaning liquid tank to the water storage tank through the suction pipe. The flow sensor can accurately measure the amount of liquid delivered into the water storage tank, ensuring the scale removal effect and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-low nitrogen through-flow gas-fired steam generator, comprising a steam generator body, a cleaning liquid tank installed on the upper side of the steam generator body, a liquid pump installed on the outer side of the cleaning liquid tank, a flow sensor installed on the outlet pipe of the liquid pump, a suction pipe installed on the inlet end of the liquid pump, a water storage tank installed on the outer side of the steam generator body, a liquid level window installed on the water storage tank, a water pump connected to the lower side of the water storage tank via a pipe, an outlet pipe installed on the outlet end of the water pump, a reverse osmosis filter element installed on the outlet pipe, and a wastewater pipe installed on the reverse osmosis filter element.

[0006] Furthermore, a drain pipe is installed on one side of the water outlet pipe, a control panel is installed on the other side of the steam generator body, and a water level gauge is installed on one side of the control panel.

[0007] Furthermore, a burner is installed on the lower side of the control panel, a safety valve is installed on the upper side of the steam generator body, and a steam pipe is installed on one side of the safety valve.

[0008] Furthermore, a pressure gauge is connected to the steam pipe, and a pressure controller is installed on the side of the pressure gauge away from the steam pipe.

[0009] Furthermore, the water storage tank is welded to the steam generator body, and the liquid pump is connected to the water storage tank via a pipeline.

[0010] Furthermore, the drain pipe is connected to the steam generator body via a thread.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: an ultra-low nitrogen through-flow gas-fired steam generator, including a steam generator body 1, a cleaning liquid tank 16 installed on the upper side of the steam generator body 1, a liquid pump 17 installed on the outer side of the cleaning liquid tank 16, a flow sensor 18 installed on the outlet pipe of the liquid pump 17, a suction pipe 19 installed on the inlet end of the liquid pump 17, a water storage tank 9 installed on the outer side of the steam generator body 1, a liquid level window 15 installed on the water storage tank 9, a water pump 10 connected to the lower side of the water storage tank 9 through a pipe, an outlet pipe 12 installed on the outlet end of the water pump 10, a reverse osmosis filter element 13 installed on the outlet pipe 12, and a wastewater pipe 14 installed on the reverse osmosis filter element 13.

[0020] like Figure 1-3 As shown, water is added to the storage tank 9. The water pump 10 pressurizes the water inside the storage tank 9 and delivers it to the reverse osmosis filter element 13. After filtration by the reverse osmosis filter element, the water quality is softened. The softened water enters the steam generator body 1 and is heated and evaporated into steam. The steam is discharged through the steam pipe 6. The pressure gauge 7 can measure the steam pressure inside the steam pipe 6 in real time. The safety valve 5 is adjusted by the pressure controller 8 so that the safety valve 5 can regulate the steam pressure by releasing pressure. When it is necessary to clean the scale on the inner wall of the pipe inside the steam generator body 1, the liquid pump 17 sends the cleaning liquid in the cleaning liquid tank 16 into the storage tank 9 through the suction pipe 19. The water in the storage tank 9 mixes with the cleaning liquid and enters the pipe, thereby soaking and rinsing the scale and improving the cleaning effect of the scale.

[0021] A drain pipe 11 is installed on one side of the water outlet pipe 12, and a control panel 2 is installed on the other side of the steam generator body 1. A water level gauge 4 is installed on one side of the control panel 2. The water level inside the steam generator body 1 can be observed through the water level gauge 4. The sewage generated inside the steam generator body 1 can be discharged through the drain pipe 11.

[0022] A burner 3 is installed on the lower side of the control panel 2, and a safety valve 5 is installed on the upper side of the steam generator body 1. A steam pipe 6 is installed on one side of the safety valve 5. The burner 3 can ignite and burn the mixture of gas and air to heat the water, turning the heated water into steam.

[0023] A pressure gauge 7 is connected to the steam pipe 6, and a pressure controller 8 is installed on the side of the pressure gauge 7 away from the steam pipe 6.

[0024] The water storage tank 9 is welded to the steam generator body 1. The liquid pump 17 is connected to the water storage tank 9 through a pipe. The water storage tank 9 stores the water used to generate steam. When the water level gauge 4 detects that the water level inside the steam generator body 1 is lower than the set value, the water pump 10 is adjusted by the control panel 2. After the water pump 10 is started, it transports the water in the water storage tank 9 to the heating pipe inside the steam generator body 1, thereby generating steam.

[0025] The drain pipe 11 is connected to the steam generator body 1 by a thread.

[0026] The working principle of the ultra-low nitrogen through-flow gas-steam generator provided by this utility model is as follows: Figures 1-3 As shown, during use, water is added to the storage tank 9. The water pump 10 pressurizes the water inside the storage tank 9 and delivers it to the reverse osmosis filter element 13. After filtration by the reverse osmosis filter element, the water quality is softened. The softened water enters the steam generator body 1 and is heated and evaporated into steam. The steam is discharged through the steam pipe 6. The pressure gauge 7 can measure the steam pressure inside the steam pipe 6 in real time. The safety valve 5 is adjusted by the pressure controller 8 so that the safety valve 5 can regulate the steam pressure by releasing pressure. When it is necessary to clean the scale on the inner wall of the pipe inside the steam generator body 1, the liquid pump 17 sends the cleaning liquid in the cleaning liquid tank 16 into the storage tank 9 through the suction pipe 19. The water in the storage tank 9 mixes with the cleaning liquid and enters the pipe, thereby soaking and rinsing the scale and improving the cleaning effect of the scale. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
