One-segment type energy saving coal gas producer with performance of two-segment producer

Abstract

The invention discloses a one-segment type energy saving coal gas producer with the performance of a two-segment producer, which aims to solve the problems of serious pollution and the like existing in the prior art. The coal gas producer comprises a producer body and a dry distillation tower, wherein the dry distillation tower comprises a dry distillation tower body arranged on the upper part of the producer body and a coal separator arranged in the producer body; because the outside of the dry distillation tower body is provided with a heat insulated device, the heat is accumulated in the tower, and the internal temperature is relatively high, which facilitates the generation of coal gas in the dry distillation tower; the dry distillation tower body is provided with a gas outlet on the same side of the producer body provided with a coal gas outlet, the gas outlet is outward provided with a dry distillation coal gas outlet tube which is downward inclined and communicated with a coal gas conveying tube, the pressure and the flow rate on the outlet of the coal gas producer are over those of the dry distillation coal gas, so that the dry distillation coal gas is led to enter a main pipeline, the dry distillation speed is improved, and the temperature in the dry distillation tower is increased; and the coal separator consists of a tube body segment and a dispersion opening segment, a coal separating tube of the coal separator is inserted in a producer cylinder, the dispersion opening segment of the coal separating tube is trumpet-shaped, so that the coal can be evenly and continuously charged and the dust can be prevented from generation.

Description

technical field [0001] The invention relates to a one-stage energy-saving gas generator with the performance of a two-stage furnace. Background technique [0002] The gasifier is divided into one-stage and two-stage. The one-stage gasifier has simple structure, convenient operation, low investment, short construction period, wide application range, and is widely used in various fields. However, due to the influence of the structure, the one-stage gasifier has several disadvantages: 1. It is necessary to maintain a certain height of the empty layer, and when the height of the empty layer is large, a large amount of coal powder will be carried out with the gas when the drop is added, which wastes energy. Blockage of pipelines; 2. The operation of one-stage gas furnace requires brazing and open hearth furnace, which not only produces coal powder, but also has high labor intensity and unstable gas production. 4. It is not convenient for long-distance transportation, so it is li...

AI Technical Summary

Problems solved by technology

However, due to the influence of the structure, the one-stage gasifier has several disadvantages: 1. It is necessary to maintain a certain height of the empty layer, and when the height of the empty layer is large, a large amount of coal powder will be brought out with the gas when the drop is added, which wastes energy. Blockage of pipelines; 2. The operation of one-stage gas furnace requires brazing and open hearth furnace, which not only produces coal powder, but also has high labor intensity and unstable gas production.

4. It is not convenient for long-distance transportation, so it is limited in use

However, to meet the needs of enterprises in the fields of forging, carbon, chemical industry, and steel rolling, they must not only require low investment, but also meet the needs of production, and must also meet the national environmental protection requirements and standards for energy conservation and emission reduction. Obviously, the above-mentioned existing one-stage and two-stage Both types of gasifiers have insurmountable defects

[0003] The patent number is: 200410010545.7, and the name is a gas generator that can continuously and automatically add coal, such as figure 1 As shown: a vertical coal pipe is installed inside the furnace body, and a water jacket 35 is arranged on the outer wall of the vertical coal pipe. The gas generator with this structure can evenly add coal, reduce coal dust production, and reduce labor intensity. But there are following defects, the water jacket 35 greatly reduces the temperature in the furnace, and the retort effect is poor; secondly, the retort gas outlet is arranged in the furnace body, which is mixed with the gas inside the furnace body and is difficult to discharge; the water jacket 35 There is no steam outlet in the part placed in the furnace body, and there is a danger of explosion
