Embodiment 1

[0038] Such as figure 1 and 2 As shown, the present embodiment provides a gasifier system including a gasification furnace body 1, a semi-cross collecting device 2, and a fly ash collection device 3, wherein

[0039]The gasification furnace body 1 has a semi-coke outlet 12 and a first synthetic gas outlet 11, and the semi-cross collecting device 2 is used to collect semi-focus particles generated by the gasification furnace body 1, and the half-focus exit 12 of the gasification furnace body 1 is connected. The half-coke collection device 2, the semi-cross collecting device 2 also has a second synthesis air outlet 21; the fly ash collection device 3 is used to collect half-coke particles in the syngas generated in the gasification furnace body 1, fly ash collection The apparatus 3 has a synthetic gas inlet, and the first synthesis air outlet 11 and the second syngas outlet 21 communicate into the synthetic gas inlet 30 of the fly ash collection device 3 to cause syngas collection i...

Embodiment 2

[0059] Such as Figure 3-5 As shown, the basic setting of the gasifier system in this embodiment is the same as in the first embodiment, and the only difference is:

[0060] Such as image 3 As shown, the gasification furnace body 1 is also provided with an inner conductive discharge tube 7, and the bottom region within the gasification furnace body 1 forms a half-focus buffer 10, and the inner conducting discharge column 7 is located above the half-focus buffer 10, within the introduction. The outer wall of the discharge column 7 is formed between the inner wall of the gasification furnace body 1, and the first synthetic air outlet 11 communicates with the annular space 70. The arrangement of the inner guide drum 7 can increase the synthetic gas flow rate at the middle of the gasified body, which is advantageous for the preliminary inertia separation of semi-focus and syngas.

[0061] Since the inertial separation is not stable enough, the half-channel of the synthetic gas entragon...

Abstract

The invention relates to a gasifier system and a semi-coke distribution control method thereof.The gasifier system comprises a gasifier body, a semi-coke collecting device and a fly ash collecting device, a semi-coke outlet of the gasifier body communicates with the semi-coke collecting device, and a first synthesis gas outlet communicates with the fly ash collecting device; the semi-coke collecting device is further communicated to the inlet end of the fly ash collecting device, a main path valve is arranged between the first synthesis gas outlet and the fly ash collecting device, an auxiliary path valve is arranged between the semi-coke collecting device and the fly ash collecting device, and when the material level in the semi-coke collecting device reaches the first material level height, the opening degree of the main path valve is increased, and the opening degree of the auxiliary path valve is reduced; and when the material level in the fly ash collecting device rises, or when the material level in the fly ash collecting device reaches a second material level height, the opening degree of the main path valve is reduced, the opening degree of the auxiliary path valve is increased, and the material level in the semi-coke collecting device rises, so that the gasification furnace system can better adapt to the optimal working state under full-load operation.

Description

Technical field [0001] The present disclosure relates to the field of coal gasization, and more particularly to a gasifier system and a semi-coking allocation control method. Background technique [0002] Hydrogenation refers to reacting carbonaceous compounds and hydrogen in a medium temperature (700 ~ 1000 ° C) and high pressure (5 ~ 10 mPa) conditions, and is a crude gas, high value-added aromatic oil, and high thermal value, but The gasification furnace is a common equipment used to conduct a gasification reaction. Typically, after the bottom of the gasifier, the reactive half-focus and syngas are separated after the initial air solid inertia separation, most of the half-focus falls to the half-focus buffer, and then discharged by the lock system. A small part of the half-coke is eluted eluted elsewhere by the synthesis gas tramp over the synthetic gas outlet, and the semi-focus separated in the process is also discharged through the lock system. [0003] If you want to make ...
