Abstract
The utility model provides a semi-watergas generating system which comprises a plurality of gas furnaces, wherein a steam pipe and an air inlet pipe are connected with the plurality of gas furnaces, the plurality of gas furnaces are formed into a set of single system, one uplink pipe of each gas furnace is communicated with a wind blowing header pipe through a wind blowing gas return valve, the wind blowing header pipe is communicated with a dust remover of the wind blowing header pipe, the other uplink pipe of each gas furnace enters into a single system gas header pipe through a gas header valve after merging a downlink gas pipeline by an uplink gas valve, and the single system gas header pipe is communicated with the dust remover of the gas header pipe. The semi-watergas generating system reduces a common passageway of uplink gas and wind blowing gas in flow path, thereby preventing a large number of residual wind blowing gas in the common passageway from entering into a gas system when the wind blowing of the gas furnaces is transformed to the gas generating. In the flow path, the unavoidable wind blowing gas in the common passageway can be taken as adjustable gas, and the adjustable gas can be sent into a wind blowing system and the gas system as required by means of time delay or non-time delay. The semi-watergas generating system increases the effective gas components in the gas and increases the adjusting leeway of recycle hydrogen in a production system.
Description
Technical field
The utility model relates to the atmospheric fixed bed intermittent coal gas technical field of Coal Chemical Industry industry semi water gas generating system.
Background technology
Generally adopt " stove one device " device in atmospheric fixed bed intermittent coal gas field, promptly a gas furnace is provided with a fly-ash separator, to blowing air and semi-water gas dedusting.Up coal gas when its flow process is the blowing air in gas furnace when blowing or system gas flow process after blowing air recovery valve or up gas valve, coal main valve enter respectively after ascension pipe advances fly-ash separator.Shortcoming is that gas furnace is transferred to by blowing when blowing, and a large amount of blowing air of accumulating in gas furnace ascension pipe and the fly-ash separator enter coal gas system, reduces unit time semi-water gas quality; It is unfavorable that synthetic ammonia is joined pure production equipment (the particularly higher device of ammonia-alcohol ratio), increases the compressor power consumption and reduce system's production efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to avoid gas furnace to be transferred to by blowing when blowing, and a large amount of blowing air of accumulating in gas furnace ascension pipe and the fly-ash separator enter coal gas system, reduces unit time semi-water gas quality; A kind of raising unit time semi-water gas quality is provided, and the semi water gas generating system of convenient as required adjusting semi-water gas gaseous constituent.
The purpose of this utility model is achieved in that a kind of semi water gas generating system, comprise gas furnace, vapour pipe is connected with gas furnace with the air admission pipe, many gas furnaces constitute a cover monophyly, the ascension pipe of gas furnace lead up to the blowing return-air valve communicate with the blowing air house steward, blowing air house steward communicates with blowing house steward fly-ash separator, another road of up gas pipe of gas furnace enters the monophyly gas main by the coal main valve after up gas valve and the merging of descending gas line, the monophyly gas main communicates with the gas main fly-ash separator.Four gas furnaces constitute a monophyly.Up gas valve and blowing return-air valve are time-delay valve.
The semi water gas generating system that the utility model provides has following effective effect:
1. native system is because blowing air and up coal gas just entered different pipeline flow processs respectively before entering fly-ash separator, and not at shared fly-ash separator, and common conduit shortens greatly, effectively overcome the defective that a large amount of blowing air enter coal gas system in the prior art.If gas furnace cycling time be 120 seconds, the fly-ash separator volume is 40m
3, then in the traditional process, will 40m be arranged approximately in every each circulation of gas furnace
3, 1200m is per hour arranged
3Blowing air (CO
2+ N
2) enter the semi-water gas system.Device according to the design's the process development has then thoroughly solved this problem.
2. set up gas valve and blowing air recovery valve delay procedure, can be further changeed when blowing remaining part blowing air in the ascension pipe blowing stage and send into the N that the burning of blowing air system or coal gas system are used for regulating semi-water gas as required
2Content.
3. above-mentioned two aspect The Application of Technology can make the N in the coal gas that atmospheric fixed bed intermittent coal gas stove produces theoretically
2Gaseous constituent is reduced to 0, makes in the actual production convenient to the adjusting of coal gas gaseous constituent.Simultaneously, based on this kind reason, the N of blowing stage in sending into coal gas system
2Gas ingredients reduces, and can make full use of more to blow to add the nitrogen amount or add the nitrogen time to promote and keep furnace temperature and guarantee the back N of workshop section
2The needs of gas ingredients, corresponding minimizing blow-time and increase the system gas time.Practice shows, under equal conditions can reduce blow-time one to two second, has remarkable energy saving effect.
4. present method is carried out four gas furnace blowing air fly-ash separators of configuration and a coal gas dust removal device, with the traditional process ratio, saves half fly-ash separator, and duct arrangement is simple, and flow process is short and sweet.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is traditional gas generating system structure diagram.
Fig. 2 is a structure diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises gas furnace 1, vapour pipe 2 is connected with gas furnace 1 with air admission pipe 3, many gas furnaces 1 constitute a cover monophyly, the ascension pipe 4 of gas furnace 1 lead up to the blowing return-air valve 5 communicate with blowing air house steward 12, blowing air house steward 12 communicates with blowing house steward fly-ash separator 6, up gas pipe 4 another roads of gas furnace 1 enter monophyly gas main 10 by coal main valve 9 after up gas valve 7 and descending gas line 8 merge, monophyly gas main 10 communicates with gas main fly-ash separator 11.Four gas furnaces 1 constitute a monophyly.Up gas valve 7 and blowing return-air valve 5 are time-delay valve.
Principle of work of the present utility model is as follows: steam is by vapour pipe 2, air enters gas furnace 1 by air admission pipe 3, is a cover monophyly according to operational characteristic with four gas furnaces 1, monophyly is established blowing air house steward fly-ash separator 6 and gas main fly-ash separator 11 each, cancels former single stove blowing air and up coal gas dust removal device.Be divided into two-way after the up gas pipe 4 of gas furnace 1 ejects, the one tunnel enters blowing air house steward 12 through blowing air recovery valve 5, and house steward's fly-ash separator 6 and back workshop section again go to dry; Another road enters monophyly gas main 10 through coal main valve 9 again after up gas valve 7 and descending gas line 8 merge, go to gas main fly-ash separator 11 and back workshop section again.Up gas valve 7 of design and blowing air recovery valve 5 deferred action programs in control, its length of whether delaying time, delay time is made amendment according to needs.
