Description

Technical Field

[0001] The invention relates to the technical field of gasifiers, and in particular to a feeding and slag-discharging integrated movable bed gasifier. Background Art

[0002] The feeding and slag-discharging integrated movable bed gasifier is a special gasifier, and its structure usually includes key components such as furnace body, feeding system, gasification zone, combustion zone, slag discharge system and control system. These components work together to realize the continuous feeding, gasification, combustion and slag discharge process of solid fuel. The feeding and slag-discharging integrated movable bed gasifier has broad application prospects in the fields of energy conversion and chemical industry. It can convert solid fuel into combustible gas for power generation, heating or fuel gas and other purposes. At the same time, by continuously optimizing the structure and working principle of the gasifier, the fuel utilization rate and gas output can be improved, and contribution can be made to sustainable development. The working principle of the feeding and slag-discharging integrated movable bed gasifier is based on pyrolysis and partial oxidation reactions. The solid fuel undergoes pyrolysis reaction under high temperature and oxygen-deficient conditions to generate combustible gas and solid residue. The combustion zone provides the required heat energy to enable the fuel to undergo pyrolysis reaction. The combustible gas is discharged from the gasifier through the slag discharge system and can be used for energy supply or chemical reaction after purification and treatment.

[0003] The integrated feeding and slag discharging system and movable bed design enable the gasifier to achieve continuous and stable operation, which is crucial for large-scale industrial production. In the chemical, energy and other industrial fields, a stable supply of synthesis gas is the guarantee for the smooth progress of subsequent production processes. For example, in the synthetic ammonia industry, a large and stable source of hydrogen is required. The integrated feeding and slag discharging movable bed gasifier can continuously provide hydrogen-rich synthesis gas to meet the needs of synthetic ammonia production and avoid stagnation of the entire production process due to interruption of the gasification process. However, the integrated feeding and slag discharging movable bed gasifier will generate a large amount of dust when adding materials, and the feed port may be stuck.

[0004] However, the existing devices have the following problems:

[0005] In the prior art, the integrated movable bed gasifier for feeding and discharging slag generates a large amount of waste gas when burning fixed materials, including harmful substances such as carbon dioxide and sulfide. If not discharged properly, it may cause pollution to the environment. At the same time, when conveying raw materials to the integrated movable bed gasifier for feeding and discharging slag, it is not convenient to convey the raw materials to the gasifier more evenly, which may cause material jamming at the feed inlet due to excessive accumulation of raw materials, and may also increase the problem of excessive dust during feeding. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the shortcomings of the prior art, the present invention provides an integrated movable bed gasifier for feeding and discharging slag, which has the advantages of purifying the generated waste gas and preventing material jamming at the feed port, thereby solving the problem of preventing the environmental pollution caused by unpurified and unfiltered waste gas and the problem of material jamming at the feed port when transporting raw materials into the gasifier.

[0008] (II) Technical solution

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a feeding and slag-discharging integrated movable bed gasifier, which has the following beneficial effects:

The design of the screw rod can adapt to raw materials in various forms to ensure that there will be no material jamming, thereby preventing the problem of clogging the feed pipe due to excessive raw materials in the feeding bin. At the same time, since it is not convenient to transport the raw materials to the inside of the furnace body at a uniform speed, a large amount of dust will appear at the feed pipe, thereby reducing the problem of fuel gas quality, further improving the practicality of the feeding and slag-discharging integrated movable bed gasifier, and by means of the support The setting of the support plate can support the entire furnace body, further ensuring the overall stability of the integrated movable bed gasifier with feeding and slag discharge. The exhaust gas pipe, conveying pipe, purification barrel, pipeline and filter bin are coordinated and set. When the furnace body burns the raw materials, the exhaust gas generated during the combustion can be conveyed to the interior of the purification barrel through the exhaust gas pipe and the conveying pipe. The exhaust gas can be moistened and purified by the purification barrel, and the purified exhaust gas can be conveyed to the interior of the filter bin through the pipeline for filtering again, so as to meet the emission standards and prevent the problem of discharging unpurified gases into the atmosphere to pollute the environment, thereby further improving the environmental protection of the integrated movable bed gasifier with feeding and slag discharge.
