Abstract
The invention relates to a method for maintaining a gas producer in a hot stand-by state. The method comprises the following steps of: (1) disconnecting an output pipe of the gas producer and a gas pipe network; (2) closing an air blast valve; (3) gradually opening a bell type valve of the gas producer and opening a dispersing pipe; (4) extinguishing the gas producer for 3-4h by using steam with the pressure of 0.2MPa, cooling a drying layer and a dry distillation layer in material layers, and slowing down the gasification reaction speed of a reduction layer and an oxide layer; and (5) enabling the gas producer to be in the hot stand-by state, and maintaining the gas outlet temperature to be within the range of 60-100 DEG C. According to the method, the energy waste is reduced, the labor intensity of workers is lightened, and the emission of waste gas and the pollution to the atmosphere are reduced.
Description
Technical field
The present invention relates to a breeding stove method, the special standby foster stove that is fit under the producer gas generator hot stand-by duty.
Background technology
MQL3.0 shape coal-gas producer is that to adopt coal or coke be raw material, take air and steam as vaporized chemical, by the inflammable gas equipment of physical-chemical reaction production take an oxygen carbon as main component.Raw material is added by the feeding device on stove top, and then gas preheating, drying through rising pass through destructive distillation, reduction, a series of gasification reactions of oxidizing fire, produce coal gas in producer gas generator.The inside of producer gas generator is divided into the levels such as dead level, drying layer, destructive distillation layer, reducing zone, zone of oxidation and grieshoch, the inner bed of material is held by fire grate, the vaporized chemical of air and vapor composition is blown into from lower furnace, the coal gas of producing flows to the user by gas outlet tube, ash content is leaked down by the hole of fire grate, is discharged by mucking machine.
Generally, producer gas generator is carried out shove charge, some stove, coal, the operation such as be incorporated into the power networks, coal gas is qualified to be incorporated into the power networks.Along with the change of user's rhythm of production, the coal gas usage quantity changes, and need to withdraw from one or more operation producer gas generator (be generally withdraw from long period re-use).Be incorporated into the power networks for the producer gas generator that withdraws from can be dropped at any time, reduce rekindling producer gas generator number of times (owing to rekindling producer gas generator, expense is higher, and labour intensity is large), producer gas generator adopts hot stand-by duty.To producer gas generator, change the hot stand-by duty concrete operation step over to by running status: (1) uses two vertical tube water seals of producer gas generator, and producer gas generator output tube and pipe network are disconnected; (2) turn on the gas-fire the gradually belljar valve of producer is opened bleeder; (3) close gradually producer gas generator air blast (air) valve, out-of-blast; (4) stop producer gas generator ash discharge and coal, (5) open the natural ventilation valve, make producer gas generator be in hot stand-by duty.
Change the operation steps of the state of being incorporated into the power networks over to according to the producer gas generator hot stand-by duty: (1) closes the natural ventilation valve; (2) open air inlet valve, carry out air blast; (3) producer gas generator was supported stove 1～2 hour, coal 2～3 times, each coal is 800Kg approximately, understands level in stove by post librarian use drill rod, makes the producer level normal; (4) get coal gas sample chemical examination, chemically examine qualified after, remove pair vertical tube water seals of producer gas generator outlet pipe, producer gas generator outlet pipe and gaspipe network are incorporated into the power networks.
According to the operation technological requirement of producer gas generator, to the standby producer gas generator of Long Time Thermal, every 24 hours, should support stove according to the operation steps that coal gas generation hot stand-by duty changes the state of being incorporated into the power networks over to, to guarantee that producer gas generator can be incorporated into the power networks at any time.The producer gas generator hot stand-by duty is supported stove, increases post personnel's labour intensity; Support between the campaign, waste a large amount of fuel and wind energy; Because producer gas generator is not incorporated into the power networks, pull open bleeder, pollute to atmosphere.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of foster stove method under producer gas generator hot stand-by duty, can reduce energy dissipation; Reduce the post personnel labor intensity; Reduce the discharging of waste gas and to topsoil.
The present invention solves the technical scheme that its technical problem takes: comprise the following steps: that (1) producer gas generator output tube and gaspipe network disconnect; (2) close the air blast valve; (3) turn on the gas-fire the gradually belljar valve of producer is opened bleeder; (4) use 0.2Mpa pressure steam, the stove 3～4 hours of going out reduces drying layer in the bed of material, destructive distillation layer temperature, slows down reducing zone, zone of oxidation gasification reaction speed; (5) make producer gas generator be in hot stand-by duty, stove goes out temperature and remains on 60～100 ℃.
1), according to the operation technological requirement of crude gas producer the present invention has following advantages:, needed 24 hours once support stove to the hot reserve producer gas generator.The present invention extends the interval time that producer gas generator is supported stove, reaches 480 hours most, reduces producer gas generator and supports the heat number.2), calculate according to producer gas generator hot reserve 480 hours, approximately 32000～48000Kg of coal economizes in raw materials; Reduce the post personnel and support stove 20 times; Simultaneously, also save a large amount of wind energies.3), improved efficiency, reduce the post personnel labor intensity; Reduce the energy consumption of producer gas generator; Simultaneously, reduce the discharging of waste gas and to topsoil.
Embodiment
To producer gas generator out of service, in advance that standby producer conditioning of BF is good when needing Long Time Thermal standby, keep normal gradation, the coal gas chemical examination is qualified.
Concrete operation step: (1) uses two vertical tube water seals of producer gas generator, and producer gas generator output tube and pipe network are disconnected; (2) turn on the gas-fire the gradually belljar valve of producer is opened bleeder; (3) close gradually producer gas generator air blast (air) valve, out-of-blast; (4) stop producer gas generator ash discharge and coal; (5) use 0.2Mpa pressure steam, the stove 3～4 hours of going out reduces drying layer in the bed of material, destructive distillation layer temperature, slows down reducing zone, zone of oxidation gasification reaction speed; (6) open the natural ventilation valve, make producer gas generator be in hot stand-by duty, stove goes out temperature and remains on 60～100 ℃.Adopt this working method, the producer gas generator hot reserve time is the longest 480 hours, and producer gas generator still can recover normal condition, produces qualified coal gas.
Claims (1)
1. the foster stove method under a producer gas generator hot stand-by duty, is characterized in that: comprise the following steps: that (1) producer gas generator output tube and gaspipe network disconnect; (2) close the air blast valve; (3) turn on the gas-fire the gradually belljar valve of producer is opened bleeder; (4) use 0.2Mpa pressure steam, the stove 3～4 hours of going out reduces drying layer in the bed of material, destructive distillation layer temperature, slows down reducing zone, zone of oxidation gasification reaction speed; (5) make producer gas generator be in hot stand-by duty, stove goes out temperature and remains on 60～100 ℃.
