Description

[Technical field]

[0001] The invention relates to a boiler, in particular to a segmented and compartmented modular heating hot water and steam dual-purpose boiler. [Background technology]

[0002] Boiler is a kind of equipment that is often needed in daily life and industrial production. Boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two parts: pot and furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. The boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. The boiler that produces steam is called a steam boiler, which is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

[0003] Traditional boilers are designed with an integrated drum and a heating furnace, where the drum for holding water is located on the top and the heating furnace for heating is located on the bottom. When in use, the water in the drum is heated by burning fuel in the heating furnace to obtain the required hot water or steam. However, traditional boilers have the following defects:

[0004] 1. When supplying steam or hot water, all saturated water below the water level in the drum needs to be heated to the required temperature before it can be provided to other equipment. This results in high energy consumption and the need to consume more fuel. The integrated design of the upper and lower structures not only has low thermal efficiency, but also poses a safety hazard when the water content of the steam is high.

[0005] 2. The combustion mode of the new gas (oil) boilers currently available on the market is that the fuel cannot be completely burned when it burns in the furnace, resulting in a large amount of fuel waste. In addition, the emission of nitrogen oxides during combustion is high, the environmental pressure is high, and the heat energy loss is also large.

[0006] 3. The existing new gas (oil) boilers and additional equipment on the market are all installed independently, which is not only extremely inconvenient to install, but also has a non-compact structure and a large overall size. [Summary of the invention]

[Specific implementation method]

[0070] The embodiment of the present invention solves the technical problems of high energy consumption, low thermal efficiency and potential safety hazards existing in traditional boilers by providing a modular hot water and steam dual-purpose boiler with segmented and compartmented heating, and achieves the technical effect of reducing energy consumption, improving thermal efficiency and ensuring safe use.

[0071] The technical solution in the embodiment of the present invention is to solve the above problems, and the overall idea is as follows: the saturated water previously stored below the water level line of the integrated boiler is stored in a plurality of completely independent sub-compartments in the water volume box by means of segmented compartments; the heat exchange of each sub-compartment is performed by a heater segment arranged in each sub-compartment, and each sub-compartment is heat exchanged separately through the segments of each heater, thereby reducing energy consumption and improving thermal efficiency in turn; at the same time, various automatic control devices are arranged on the water volume box to ensure the safety of boiler use.

[0072] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0073] See also Figures 1 to 9 As shown, the present invention is a segmented and compartmented modular hot water and steam dual-purpose boiler 100, the boiler 100 comprising:

[0074] A water volume box 1, in which at least a pressure chamber 11, a heating chamber 12 and an auxiliary heating chamber 13 are independently arranged in sequence. In a specific implementation, the pressure chamber 11, the heating chamber 12 and the auxiliary heating chamber 13 can be arranged in sequence from left to right or from right to left. The water volume box 1 needs to be made of a material that is resistant to high temperatures and has a heat insulation function; the auxiliary heating chamber 13 is connected to the heating chamber 12, and the auxiliary heating chamber 13 supplies water to the heating chamber 12 by gravity or transportation. In a specific implementation, at least one hot water gravity channel (not shown) can be set between the auxiliary heating chamber 13 and the heating chamber 12, so that after the liquid level of the heating chamber 12 drops, the water in the auxiliary heating chamber 13 can automatically flow into the heating chamber 12; of course, the water in the auxiliary heating chamber 13 can also be transported to the heating chamber 12 by a water pump or the like;

[0075] a heater 2, wherein the heater 2 is arranged in sections in the pressure chamber 11, the heating chamber 12 and the auxiliary heating chamber 13, and the water in the pressure chamber 11, the heating chamber 12 and the auxiliary heating chamber 13 is heat-exchanged by the heater 2;

[0076] At least one vacuum pressure water pump 3, the vacuum pressure water pump 3 is fixedly arranged on the top of the water volume box 1, and the heating chamber 12 injects water into the pressure chamber 11 through the vacuum pressure water pump 3; in specific implementation, two vacuum pressure water pumps 3 can be arranged on the top of the water volume box 1, so that in specific operation, water can be continuously injected into the pressure chamber 11 through the two vacuum pressure water pumps 3;

[0077] a boiler output main pipeline 4, the boiler output main pipeline 4 is connected to the pressure chamber 11, so as to output hot water or steam through the boiler output main pipeline 4 and provide it to other equipment for use;

[0078] An auxiliary heating bin water supply pipe 5 is connected with the auxiliary heating bin 13 to supply water to the auxiliary heating bin 13 through the auxiliary heating bin water supply pipe 5. In a specific implementation, the auxiliary heating bin water supply pipe 5 can be connected to a tap water network (not shown) to provide the required water for the entire boiler 100.

[0079] From the above, it can be seen that the present invention stores the saturated water previously stored below the water level line of the integrated boiler in three completely independent sub-compartments (i.e., the pressure compartment 11, the heating compartment 12, and the auxiliary heating compartment 13) in the water volume box 1 by means of segmented compartments; and the heat exchange of each sub-compartment (i.e., the pressure compartment 11, the heating compartment 12, and the auxiliary heating compartment 13) is performed by a heater 2 which is segmented and arranged in each sub-compartment (i.e., the pressure compartment 11, the heating compartment 12, and the auxiliary heating compartment 13), and heat exchange is performed on each sub-compartment (i.e., the pressure compartment 11, the heating compartment 12, and the auxiliary heating compartment 13) by means of the segmentation of each heater 2. Through this segmented compartment method, when each segment of the heater 2 performs heat exchange with the water in each compartment in the water volume box 1, the water in each compartment (i.e., the pressure compartment 11, the heating compartment 12, and the auxiliary heating compartment 13) can be heated as a whole without mixing heat, that is, each compartment can play its own different role, wherein the pressure compartment 11 is used to provide hot water or steam required for daily life or industrial production, the heating compartment 12 is used to provide hot water to the pressure compartment 11 uninterruptedly, and the auxiliary heating compartment 13 is used to replenish water to the heating compartment 12 in time. Through the technical solution of the present invention, on the one hand, due to the use of the segmented compartment heat exchange method, it can effectively avoid the need for traditional boilers to heat all the saturated water below the water level line in the integrated boiler to the required temperature when supplying steam or hot water, thereby reducing fuel loss and low energy consumption; on the other hand, due to the full utilization of thermal energy through the segmented compartment method, it can improve thermal efficiency.

In the specific implementation of the present invention, two manual pressure reducing valves 64 are provided;

[0085] At least one check valve 65, the vacuum pressure water pump 3 is connected to the top of the dome 61 through the check valve 65; the check valve 65 is mainly used to prevent the hot water or steam in the pressure chamber 11 from flowing back into the heating chamber 12.

[0089] When the boiler 100 of the present invention is in use, when hot water of about 95°C is needed, the two manual pressure reducing valves 64 need to be fully opened so that superheated steam can be discharged from the manual pressure reducing valves 64. When high-temperature hot water of about 120°C is needed, the two manual pressure reducing valves 64 need to be fully closed, and when filling water, the two manual vacuum exhaust valves 63 need to be opened to fill the dome 61 with water, and keep the dome 61 in a vacuum state to prevent hot water from vaporizing. When steam is needed, the two manual pressure reducing valves 64 need to be fully closed to pressurize the pressure chamber 11 to the set pressure safety index. At the same time, in the above process, the first temperature automatic control device 67 and the pressure automatic control device 66 can be used to automatically control the temperature and pressure to ensure the absolute safety of the entire production process.
