The gasification layer is controlled to be relatively stable, carbon conversion rate of materials is increased, consumption is reduced, component of inert gas is steady, and changing time is shortened.
Description
Technical field:
The utility model belongs to producer gas generator rare gas element production field, is that a kind of producer gas generator of saving consumption, stable gasification layer is produced the effective technology of rare gas element, is applicable to coal gas system maintenance metathetical advanced technologies.
Background technology:
Gas Production, induction system must be replaced when maintenance is got angry, and nitrogen making machine group or high concentration CO more than needed are arranged
2The producer of gas adopts nitrogen or high concentration carbon dioxide gas to replace, and the producer that does not possess this condition then must produce inert gas by gas generator and replace.Blow two stages of steam blowing on air and the bottom on bottom the method for traditional producer gas generator production rare gas element has only.Bottom blowing up steam phase is that steam enters from the gas generator bottom, produces coal gas through the gasification layer reaction, and coal gas comes out from top, carries out emptying after cyclone dust removal, decreases through this stage gasification layer temperature.Blowing the air stage on the bottom is that air enters from the producer gas generator bottom, produces rare gas element (main component CO through the reaction of gasification layer
2, CO
2+ H
2≤ 8%), utilize this gas that pipeline, the equipment of system are replaced, this stage gasification layer temperature raises to some extent.
The gas generator structure is that the gas generator bottom is provided with lower inlet pipe, upper outlet pipe, the upper and lower total valve that is communicated with it, the steam source pipe is communicated with gas generator lower inlet pipe by lower inlet valve, lower inlet valve respectively with the air gas source pipe, this inlet tube simultaneously also with lower total valve pipeline connection; Gas generator is communicated with upper total valve by the upper outlet pipe, upper inlet valve of bypass between upper total valve and the gas generator, upper inlet valve is communicated with the steam source pipe, upper and lower total valve respectively with the waste heat exchanger pipeline communication, noble gas is produced exhaust-valve in of upper total valve and the bypass of gas generator connecting pipe in order to replace; Producing the waste gas of indifferent gas process is discharged by upper exhaust-valve.But lower exhaust-valve of the no bypass of pipeline between lower total valve and gas generator, if the waste gas that upper inlet valve admission produces can't discharge, therefore the production of inert gas can only be based upon on the circular flow basis in two stages, and the major defect of its existence is as follows:
1, owing to be in the gas uplink state all the time, the furnace temperature of producer gas generator is high easily, and trip temperature surpasses 500 ℃ easily on the blowing stage especially, causes the situation of the waste heat exchanger generation booster of waste heat recovery;
2, in order to control furnace temperature, when temperature reaches 450 ℃ of left and right sides, must move by shut down procedure, suitably add materials, control its temperature, increase operative employee's labour intensity;
3, the production of inert gas should be in low carbon-coating, moves under the low furnace temperature state, is conducive to control fuel gas content.For controlling this situation, ceaselessly adding material is ceaselessly discharged the reaction slag, forms the eating and discharging situation.Under this situation, cause the gasification layer rather unstable, the carbon conversion ratio of material is low, consumption is high, and the indifferent gas constituent content instability of producing simultaneously is so that the time lengthening of system's displacement;
4, the replacement process of driving behind system overhaul transfers the production semiwater gas to after inert gas replacement is qualified, because the instability of gasification layer causes semiwater gas oxygen content height easily, and time and safety that impact is driven.
Summary of the invention:
The purpose of this utility model is to provide a kind of inert gas producing device of stable gasification layer, improves the efficient that inert gas is produced, and reduces the consumption of producing inert gas, stablizes gasification layer, and semiwater gas processed is created good condition in order to drive.
Scheme of the present utility model is: following exhaust-valve of bypass on pipeline between following total valve and the producer gas generator.
Advantage of the present utility model is: increased steam blowing on steam blowing under the top, the bottom secondary, bottom and blown the air stage on first, each step conversion is based on the working time in stage of program setting, it is up to have avoided original program to be in gas all the time, the furnace temperature height, constantly blowing out is reinforced, gobbles big row's situation, realized steam blowing stage self-feeding under the top, effectively control furnace temperature, avoided overtemperature to cause the waste heat exchanger booster, reduced operative employee's labour intensity simultaneously greatly.All the time up situation of gas has been eliminated in the change of program, and gasification layer control obtains relative stable, and the carbon conversion ratio of material improves, and the consumption of producing inert gas is reduced, and the inert composition of producing gained is stable, has greatly shortened the time of displacement.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
Operational outfit of the present utility model comprise producer gas generator (3), down total valve (8), down admission valve (2), lower inlet valve (1), go up admission valve (7), go up total valve (5), waste heat exchanger (6), go up exhaust-valve (4), steam source pipe, air source of the gas pipe, it is characterized in that; A following exhaust-valve of bypass (9) on pipeline between following total valve (8) and the producer gas generator (3).
The inert gas production stage is: each stage of respective valves is controlled respectively keying, carries out following operation:
1. the first upper steam blowing in bottom is discharged by upper exhaust-valve (4);
2. steam blowing under the top is discharged by following exhaust-valve (9);
3. steam blowing on the secondary of bottom is discharged by upper exhaust-valve (4);
4. the first blowing up air in bottom is discharged by upper exhaust-valve (4);
5. blow air on the secondary of bottom and produce rare gas element through the gasification layer, rare gas element enters waste heat exchanger (6) by last total valve (5) and cools off.
Flow process is as follows: producer gas generator (3) is produced the rare gas element program and is divided into the first steam blowing on steam blowing, the bottom secondary, bottom gone up under steam blowing, the top in bottom and blows on first and blow on air, the bottom secondary five stages of air.The bottom secondary blowing up air stage is that air enters from gas generator (3) bottom, makes inert gas through the gasification layer reaction, comes out coal gas system is replaced from top, and this stage produces heat.The first blowing up steam phase in bottom is that steam enters from gas generator (3) bottom, emptying after the reacted gas of gasification layer comes out from top, and this stage is to absorb the gasification layer heat.Top blowing down steam phase is that steam enters from gas generator (3) top, come out to carry out emptying through lower exhaust-valve from the bottom after the gasification layer reaction, this stage is to absorb the gasification layer heat, simultaneously from top to bottom, the particularly cooling on gasification layer upper strata, the control stable gasification layer.Bottom secondary blowing up steam phase flow process and the first blowing up vapor phase in bottom are to prevent from directly entering the first blowing up air stage of bottom after top blowing down steam phase from finishing together, and coal gas and air mixed occurrence that top blowing down steam phase residues in the bottom explode.It is that air enters from the bottom that the air stage is blown on the secondary in the bottom, carries out emptying after coming out from top behind the gasification layer, and this stage is that the coal gas that stove top is residual purges, and prevents that it from entering system.
