Description
本实用新型属于锅炉技术领域，主要涉及的是一种内热式下排烟高效气化环保锅炉。The utility model belongs to the technical field of boilers, and mainly relates to an internal heating type bottom-exhaust smoke efficient gasification environmental protection boiler.
现有的锅炉，在对余热的利用方面采取的措施有：由炉芯散发的余热通过炉体内的水吸收；烟气中的余热则通过在烟道外设置水套来吸收。由于炉芯在气化燃烧过程中其散发的热量被炉体内的水吸收，从而影响了炉芯内的气化温度，进而影响到燃烧效果，使烟气中的烟尘较大，不利于环境保护。而烟气中的余热虽部分被水套内的水吸收，但由于其为上排烟结构，尽管有的锅炉延长了排烟道，但烟气中的大部分余热还是被白白浪散掉。In the existing boilers, the measures taken in the utilization of waste heat include: the waste heat emitted by the furnace core is absorbed by the water in the furnace body; the waste heat in the flue gas is absorbed by setting a water jacket outside the flue. Since the heat emitted by the furnace core is absorbed by the water in the furnace body during the gasification combustion process, the gasification temperature in the furnace core is affected, which in turn affects the combustion effect, making the smoke in the flue gas larger, which is not conducive to environmental protection . Although part of the waste heat in the flue gas is absorbed by the water in the water jacket, most of the waste heat in the flue gas is still dissipated by white waves due to its upper smoke exhaust structure, although some boilers have extended flue exhaust ducts.
本实用新型的目的即由此产生，提出一种结构设计合理、热能利用率高、气化燃烧充分、烟气污染小、节省能源的内热式下排烟高效节能环保锅炉。The purpose of this utility model is thus born, to propose an internal heating type bottom exhaust smoke efficient, energy-saving and environmentally friendly boiler with reasonable structure design, high heat energy utilization rate, sufficient gasification combustion, low smoke pollution, and energy saving.
为实现上述目的，本实用新型是通过以下技术方案实现的：其主要由炉芯和炉体组成，炉芯上设有加料口和出渣口，其内设置有炉蓖，外部设置有保热层；炉体为水套结构，其上设有进水管、排水管及排烟管；炉芯设置在炉体内，其与炉体之间形成有下排烟道，该下排烟道的下部与炉体上的下排烟管连通。In order to achieve the above purpose, the utility model is achieved through the following technical solutions: it is mainly composed of a furnace core and a furnace body. layer; the furnace body is a water jacket structure, on which there are water inlet pipes, drain pipes and smoke exhaust pipes; the furnace core is arranged in the furnace body, and a lower flue is formed between it and the furnace body, and the lower part of the lower flue It communicates with the lower exhaust pipe on the furnace body.
本实用新型设计独特，结构简单。由于其炉芯采用的是高效气化炉芯，该炉芯的出口处设有助燃孔及储热滤网，外部设有保温层，其内还可再设置助燃管，这样在保证炉芯内气化温度的同时，又使其能够充分燃烧，降低了烟气中的烟尘含量。由于炉体内的上部中心设计为呈凸凹结构的“ ”形状，因而增大了炉体的热交换面积，使其热效利用率大为提高。且其采用是下排烟结构，并且在排烟管上设置有余热回收水套，因而烟气在排放过程中其烟气中的余热被炉体内的水充分吸收，烟气中的烟尘则在自重作用下落入烟道下端，起到了节约能源、降低烟气污染的目的。The utility model has unique design and simple structure. Because the furnace core adopts a high-efficiency gasification furnace core, a combustion-supporting hole and a heat storage filter are provided at the outlet of the furnace core, and an insulation layer is provided on the outside, and a combustion-supporting tube can be set inside it, so as to ensure that the inside of the furnace core While increasing the gasification temperature, it can fully burn and reduce the soot content in the flue gas. Since the upper center of the furnace body is designed as a " "shape, thus increasing the heat exchange area of the furnace body, greatly improving the utilization rate of its heat efficiency. And it adopts a lower smoke exhaust structure, and a waste heat recovery water jacket is set on the exhaust pipe, so the flue gas is in the During the discharge process, the waste heat in the flue gas is fully absorbed by the water in the furnace body, and the dust in the flue gas falls into the lower end of the flue under the action of its own weight, which saves energy and reduces the pollution of flue gas.
本实用新型既可用煤作燃料，也可用柴、秸杆等做燃料使用。The utility model not only can use coal as fuel, but also can use firewood, straw, etc. as fuel.
