The steam is discharged through the exhaust pipe for use. This structure facilitates the addition of straw.

Description

Technical Field

[0001] This utility model relates to the field of straw combustion technology, and more specifically, to an industrial straw steam boiler structure. Background Technology

[0002] Straw burning refers to the process of burning crop straw (such as corn stalks, wheat straw, and rice straw) left over after harvest as fuel. This method of combustion is typically used to generate heat or energy, which can be used for home heating and cooking, as well as for heating or power generation in industrial production. However, open burning of straw produces large amounts of smoke, particulate matter, and harmful gases (such as carbon dioxide, sulfur dioxide, and nitrogen oxides), causing serious pollution to air quality and the environment, and also posing a fire hazard. Therefore, many countries and regions have restricted or banned open burning of straw, and instead promoted the comprehensive utilization of straw, such as returning straw to the field, biomass power generation, and biomass fuel production, to achieve sustainable resource utilization and environmental protection.

[0003] A search revealed an existing patent (publication number: CN221811326U) disclosing a biomass steam boiler, comprising a furnace body with a grate inside. An upper ring and a lower ring are located in the middle of the furnace body, with the grate rotatably connected between them. An arc-shaped groove is provided on the furnace body between the upper and lower rings, and an arc-shaped rack connected to the outer circumference of the grate is located within the groove. A motor is located on the outside of the furnace body, and the output shaft of the motor is driven by a non-fully gear meshing with the arc-shaped rack. An arc-shaped groove is provided on the outer circumference of the grate, and a limiting boss extending into the groove is provided on the inner wall of the furnace body. An elastically supporting limiting boss is located within the groove, with a spring for the grate's rotational reset. This invention uses a mechanized structure to drive the grate in intermittent rotational motion, thereby shaking off the accumulated ash from the grate, thus avoiding the tedious manual maintenance and the safety hazards associated with previous manual operations.

[0004] However, the aforementioned device still has some shortcomings in its use. First, the input of biomass pellet fuel is rather cumbersome, requiring periodic and quantitative feeding into the combustion chamber. This process necessitates manual operation or complex feeding equipment, increasing labor intensity and equipment costs. Second, the heat distribution after combustion is not concentrated enough. Although the gasification chamber can utilize flames and flue gas for heating through a coaxial arrangement, the structural limitations of the combustion chamber result in uneven heat distribution within the furnace, leading to excess heat in some areas and insufficient heat in others, thus affecting the overall thermal efficiency and steam generation effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an industrial straw steam boiler structure to solve the problems of cumbersome fuel input, uneven heat distribution, and impact on thermal efficiency and steam generation during the use of the device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an industrial straw steam boiler structure, comprising: a combustion boiler; a straw feeding device mounted on the combustion boiler, the straw feeding device being used to facilitate the addition of straw fuel and prevent smoke and dust from spreading, the straw feeding device comprising: a limiting hinge mounted on the combustion boiler, on which a feeding component is movably mounted; a baffle fixedly mounted inside the combustion boiler; a smoke removal device fixedly mounted on the rear side of the combustion boiler; a steam generating device mounted on the combustion boiler, the steam generating device being used to generate steam during heating; a wind-powered soot blowing device mounted on the combustion boiler, the wind-powered soot blowing device being used to accelerate combustion and prevent dust from caking; and an ash collection and discharge device mounted at the bottom of the combustion boiler, the ash collection and discharge device being used to collect the ash after combustion.

[0007] Preferably, the feeding assembly includes: a heat insulation plate movably mounted on the limiting hinge, an upper partition plate fixedly mounted on the heat insulation plate, and a lower partition plate fixedly mounted on the heat insulation plate.

[0008] Preferably, the smoke removal device includes: a smoke outlet stack fixedly installed on the rear side of the combustion boiler, and an air extraction pump fixedly installed on the smoke outlet stack.

[0009] Preferably, the steam generating device includes: an exhaust pipe fixedly installed on the combustion boiler, a gasification chamber fixedly installed on one side of the exhaust pipe, an enlarged area protrusion fixedly installed at the bottom of the gasification chamber, and a water inlet pipe fixedly installed on one side of the gasification chamber, the water inlet pipe being fixedly sleeved on the combustion boiler.

[0010] Preferably, the steam generating device further includes: a guide plate fixedly installed inside the combustion boiler, the guide plate being disposed at the bottom of the gasification chamber, the guide plate having smoke leakage holes, and multiple sets of smoke leakage holes being disposed at equal intervals on the guide plate.

[0011] Preferably, the wind-powered soot blowing device includes: a fan fixedly installed on one side of the combustion boiler, an installation plate fixedly installed inside the combustion boiler, and multiple sets of jet pipes arranged on the installation plate at equal intervals.

[0012] Preferably, there are two sets of the blower, mounting plate, and jet pipe, and the two sets of the blower, mounting plate, and jet pipe are equidistantly arranged on the combustion boiler.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a straw feeding device to add straw fuel to a combustion boiler. Specifically, the insulation plate is opened, and the straw is placed inside the boiler. The upper and lower partitions on the insulation plate prevent smoke and dust from escaping and provide insulation protection, ensuring the safety of the operators. When the straw burns inside the boiler, the resulting flue gas enters the gasification chamber through the smoke vents. The enlarged protrusions at the bottom of the gasification chamber effectively increase the heating area and improve heat exchange efficiency, allowing water to be quickly converted into steam within the chamber. The steam is then discharged through the exhaust pipe for use. This structure facilitates the easy addition of straw. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

Figures 1 to 5 The system includes: a combustion boiler 1; a straw feeding device 2 mounted on the combustion boiler 1, which facilitates the addition of straw fuel and prevents smoke and dust from spreading; the straw feeding device 2 includes: a limiting hinge 201 mounted on the combustion boiler 1, on which a feeding component 202 is movably mounted; a baffle 203 fixedly mounted inside the combustion boiler 1; a smoke removal device 204 fixedly mounted on the rear side of the combustion boiler 1; a steam generator 3 mounted on the combustion boiler 1, which generates steam during heating; a wind-powered ash blowing device 4 mounted on the combustion boiler 1, which accelerates combustion and prevents dust from caking; and an ash collection and discharge device 5 mounted at the bottom of the combustion boiler 1, which collects the ash after combustion.

[0025] In this embodiment, the feeding assembly 202 includes: a heat insulation plate 205 movably installed on the limiting hinge 201, an upper partition plate 206 fixedly installed on the heat insulation plate 205, and a lower partition plate 207 fixedly installed on the heat insulation plate 205.

[0026] In this embodiment, the smoke removal device 204 includes: a smoke outlet 208 fixedly installed on the rear side of the combustion boiler 1, and an air extraction pump 209 fixedly installed on the smoke outlet 208.

[0027] In this embodiment, the steam generating device 3 includes: an exhaust pipe 301 fixedly installed on the combustion boiler 1, a gasification chamber 302 fixedly installed on one side of the exhaust pipe 301, an area-enhancing protrusion 303 fixedly installed at the bottom of the gasification chamber 302, and a water inlet pipe 304 fixedly installed on one side of the gasification chamber 302, the water inlet pipe 304 being fixedly sleeved on the combustion boiler 1.

[0028] In this embodiment, the steam generating device 3 further includes: a guide plate 305 fixedly installed inside the combustion boiler 1. The guide plate 305 is located at the bottom of the gasification chamber 302. The guide plate 305 is provided with smoke leakage holes 306. Multiple sets of smoke leakage holes 306 are provided, and the multiple sets of smoke leakage holes 306 are equidistantly opened on the guide plate 305.

[0029] When using this industrial straw steam boiler, straw fuel is first added to the combustion boiler 1 via the straw feeding device 2. Specifically, the insulation plate 205 is opened, and the straw is placed into the combustion boiler 1. The upper baffle 206 and lower baffle 207 on the insulation plate 205 prevent smoke and dust from escaping and also provide insulation protection, ensuring the safety of the operators. As the straw burns inside the combustion boiler 1, the flue gas produced enters the gasification chamber 302 through the smoke vent 306. The increased area of ​​the bottom protrusion 303 in the gasification chamber 302 effectively increases the heating area and improves heat exchange efficiency, allowing water to be quickly converted into steam within the gasification chamber 302. The steam is then discharged through the exhaust pipe 301 for use. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the industrial straw steam boiler structure provided by this utility model is as follows: Figures 1 to 5 As shown: The wind-powered soot blowing device 4 includes: a blower 401 fixedly installed on one side of the combustion boiler 1, an installation plate 402 fixedly installed inside the combustion boiler 1, and multiple sets of jet pipes 403 arranged on the installation plate 402, with the multiple sets of jet pipes 403 equidistantly arranged on the installation plate 402.

[0032] In this embodiment, the ash collection and discharge device 5 includes: an installation ring 501 fixedly installed inside the combustion boiler 1, a filter plate 502 movably installed inside the installation ring 501, an ash collection chamber 503 opened inside the combustion boiler 1, and an ash discharge pipe 504 fixedly installed on one side of the ash collection chamber 503.

[0033] Simultaneously, the blower 401 starts, injecting airflow into the combustion boiler 1 through the jet pipe 403 on the mounting plate 402, accelerating the straw combustion process, preventing ash from caking in the combustion chamber, and maintaining combustion efficiency. The ash after combustion is filtered through the filter plate 502 and enters the ash collection chamber 503, then discharged through the ash outlet pipe 504 for centralized treatment. Furthermore, the exhaust pump 209 in the smoke removal device 204 extracts the flue gas generated during combustion through the flue 208, reducing environmental pollution and lowering the pressure inside the combustion boiler 1. The entire process achieves efficient combustion of straw fuel, rapid steam generation, and effective ash collection, improving the boiler's operating efficiency and environmental performance.
