Abstract
The utility model discloses a burner cooling water system, wherein the outlet end of the burner is connected with the inlet end pipeline of a separation tank; and an outlet cutout valve and a rear hand valve are orderly arranged on the pipeline which connects the outlet end of the burner with the inlet end of the separation tank. The burner cooling water system further comprises a valve instrument gas and an instrument gas storage tank, wherein the outlet of the valve instrument gas is connected with the inlet pipeline of the instrument gas storage tank; and the outlet of the instrument gas storage tank is connected with the gas inlet of an inlet cutout valve and the gas inlet pipeline of the outlet cutout valve. The burner cooling water system has the advantages that the inlet cutout valve and the outlet cutout valve of the burner cooling water system both can be closed normally no matter whether the valve instrument gas has a fault or not, so that steam explosion of the burner cooling water system and massive leaking accidents of a synthetic gas can be prevented, and therefore, the operation personnel can be guaranteed under safe environment when the front hand valve of the inlet cutout valve and the rear hand valve of the outlet cutout valve of the burner cooling water system are closed manually.
Description
Technical field
The utility model relates to a kind of burner technology of vapourizing furnace, particularly relates to a kind of burner nozzle cooling water system.
Background technology
In coal water slurry gasification technical process, coal water slurry and oxygen enter vapourizing furnace after the abundant mixed aerosol in burner place, complicated chemical reaction occurs in vapourizing furnace combustion chamber and produce synthetic gas.Burner head is in the vapourizing furnace of High Temperature High Pressure, in order to protect burner, is provided with cooling water coil and head water jacket on burner.The de-salted water (DW) of burner cooling trough pressurizes through burner cooling-water pump, deliver to burner cooling water cooler cooling, through burner cooling water inlet trip valve, send into burner cooling water coil again, the water coolant that goes out burner cooling water coil enters burner water coolant separating tank through outlet trip valve, flows into burner cooling trough after separating gas by gravity; Accident burner cooling trough is when burner cooling-water pump can not guarantee the normal discharge of burner water coolant, to burner, flow is provided and stops immediately.
Burner nozzle cooling water system entrance trip valve and outlet trip valve are FO (instrument supply gas is invalid to be opened), and magnetic valve is the normal dead electricity of NDE().When burner nozzle cooling water system stops, magnetic valve obtains electric, and burner nozzle cooling water system entrance trip valve and outlet trip valve are closed immediately, prevent the blast of burner cooling water pipeline generation water vapor, avoid causing synthetic gas to leak in a large number because burner head burns out.Meanwhile, operator's manual-lock burner nozzle cooling water system entrance trip valve remote holder valve and outlet trip valve defensive position valve.
But, if valve instrument gas fault (pressure is low or die), burner nozzle cooling water system entrance trip valve and outlet trip valve can not be closed or close and automatically be opened afterwards, may cause the blast of burner cooling water pipeline generation water vapor, and even synthetic gas leaks in a large number.In this case, when operator's manual-lock burner nozzle cooling water system entrance trip valve remote holder valve and outlet trip valve defensive position valve, will be in breakneck environment.
Utility model content
The purpose of this utility model is to provide one more safe and reliable burner nozzle cooling water system.
The purpose of this utility model is implemented by following technical scheme, a kind of burner nozzle cooling water system, it comprises burner, water cooler, burner cooling trough, burner cooling-water pump, accident burner cooling trough and separating tank, described cooler outlet end is connected with described burner inlet end pipeline, connect on the pipeline of described cooler outlet end and described burner inlet end, be provided with successively remote holder valve and entrance cutting-off valve, described burner exit end is connected with described separating tank inlet end pipeline, connect and on the pipeline of described burner exit end and described separating tank inlet end, be provided with successively outlet cutting-off valve and defensive position valve, it also includes valve instrument gas and instrument supply gas storage tank, described valve instrument gas outlet is connected with described instrument supply gas storage tank inlet duct, described instrument supply gas storage tank outlet is connected with the inlet mouth of described entrance cutting-off valve and the air inlet duct of described outlet cutting-off valve respectively.
Described valve instrument gas outlet is connected with the inlet mouth of described entrance cutting-off valve and the air inlet duct of described outlet cutting-off valve.
Valve instrument gas: for the driving source of the gas of pneumatic actuator (performer of operated pneumatic valve, cylinder etc.).In this patent, valve instrument gas is for the driving source of the gas of burner nozzle cooling water system entrance cutting-off valve and outlet cutting-off valve.
When valve instrument gas breaks down (pressure is low or die), instrument supply gas storage tank provides power as standby driving source of the gas for entrance cutting-off valve and outlet cutting-off valve, to guarantee that entrance cutting-off valve and outlet cutting-off valve normally close.
In burner nozzle cooling water system, the de-salted water (DW) of burner cooling trough is after the pressurization of burner cooling-water pump, deliver to water cooler cooling after, through entrance cutting-off valve, send into burner cooling water coil, the water coolant that goes out burner cooling water coil flows into burner cooling trough by gravity after outlet cutting-off valve enters separating tank to separate gas; Accident burner cooling trough is when burner cooling-water pump can not guarantee the normal discharge of burner water coolant, to burner, flow is provided and stops immediately.
The utility model has the advantage of, in burner nozzle cooling water system, increase instrument supply gas storage tank, can play two effects greatly: first, no matter whether valve instrument gas fault, burner nozzle cooling water system entrance cutting-off valve and outlet cutting-off valve can normally be closed, and prevent leak the in a large number generation of accident of burner nozzle cooling water system vapor explosion and synthetic gas; The second, guarantee that operator, when manual-lock burner nozzle cooling water system entrance trip valve remote holder valve and outlet trip valve defensive position valve, in safer environment, have protected operator's personnel safety.Further improved the safety performance of burner nozzle cooling water system.The utility model is simple in structure, and cost is low.
