Description
Technical field
The present invention relates to ammonia technical field, specifically a kind of pressure control control for fixed bed oxygen enhanced gasification technique
Oxygen system.
Background technology
In technique for producing synthetic ammonia gas, with the every technological progress and reducing energy consumption of fixed-bed gasification furnace, fixed bed
Oxygen enhanced gasification technology is come into being along with reducing energy consumption.Effect the most significant is exactly to change the ton of existing ammonia enterprise
Moderate, significant effect is invested in ammonia coal consumption.
But there is also deficiency in actual motion, especially under normal cloth oxygen condition, the oxygen of air header is dense
Spend more stable, but when occurring under blowing valve alarm or blowing out during ash, the oxygen concentration moment of air header increases, and gives down
One Gas-making Furnace for preparing blowing is brought many enters stove oxygen concentration than normally setting to be higher by.Especially Gas-making Furnace load is inclined in winter
It in the case of weight, easily causes to overheat in stove or what is be turned over happens, the stabilization and production to the working of a furnace are all brought no small
It influences, and the influence to the feed coal oxygen enhanced gasification of soft coal and ash-rich is the most apparent.
At this stage, typically taking reduces the method into stove wind pressure to maintain the stabilization of the working of a furnace, but so will
Decline the load of Gas-making Furnace, influence the demand of gas supply, be unfavorable for the gas supply of production, cause to supply nervous situation.
Invention content
The purpose of the present invention is to provide a kind of pressure control control oxygen system for fixed bed oxygen enhanced gasification technique, the system energy
Enough stablize the blowing load of gas making and enter the oxygen concentration of stove, the fluctuation of blowing air pressure and air header oxygen concentration is normally being given birth to
In the allowed band of production, the quality of entire gasification system is improved.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of pressure control control oxygen system for fixed bed oxygen enhanced gasification technique, blower export connection air outlet conduits, oxygen are defeated
Outlet pipe is connected after converging connection with air outlet conduits with oxygenation air header, oxygen enhanced gasification PLC and the oxygenation on oxygen output tube
Regulating valve is connected；The pressure control control oxygen system includes blow-down pipe and pressure control control oxygen PLC, one end and the oxygenation air header of blow-down pipe
Be connected, the other end is connected to blower inlet, the pipeline of blow-down pipe is equipped with emptying regulating valve；Oxygenation air header is equipped with wind
Pressure pressure transmitter and oxygen analyzer；The input that wind pressure pressure transmitter is respectively connected to pressure control control oxygen PLC with oxygen analyzer connects
Mouthful, the output interface of pressure control control oxygen PLC is respectively connected to emptying regulating valve and oxygen enhanced gasification PLC；
The oxygenation that the oxygenation air header wind pressure and oxygen analyzer that pressure control control oxygen PLC is fed back according to wind pressure pressure transmitter are fed back
Air header oxygen concentration, the aperture of control emptying regulating valve, and export oxygenation and signal is controlled to pass through oxygenation to oxygen enhanced gasification PLC
The aperture for the PLC control oxygenation regulating valves that gasify makes the wind pressure of oxygenation air header and oxygen concentration maintain to stablize.
The beneficial effects of the invention are as follows：
When the wind pressure of oxygenation air header exceeds setting value with oxygen concentration, the aperture of pressure control control oxygen PLC increase emptying regulating valves,
Extra oxygenation air is discharged via blow-down pipe, meanwhile, pressure control control oxygen PLC output oxygenation controls signal to increase to oxygen enhanced gasification PLC
Gasification PLC reduces the aperture of oxygenation regulating valve, reduces the supply of oxygenation air, so as to reduce the wind pressure of oxygenation air header with
Oxygen concentration.
When the wind pressure of oxygenation air header is less than setting value with oxygen concentration, pressure control control oxygen PLC closes emptying regulating valve, together
When, pressure control control oxygen PLC output oxygenation control signals to oxygen enhanced gasification PLC, oxygen enhanced gasification PLC increase the aperture of oxygenation regulating valve,
So as to improve the wind pressure of oxygenation air header and oxygen concentration.
Wind pressure is excessively high caused by oxygen concentration fluctuation caused by the present invention efficiently solves Gas-making Furnace blowing out and blowing out is made
Steam stove brings the generation for being turned over phenomenon；In addition, tolerance will not be caused to influence due to detaining wind pressure in lower ash, it is nervous to alleviate gas supply
Production status, ensure production need；Oxygen concentration and wind pressure under big load is made to be protected.
