Description
Technical field
The utility model relates to a kind of heat-exchange system, relates to a kind of Gas-making Furnace chuck fused salt heat exchanging system specifically.
Background technology
Chuck is the utility appliance of atmospheric fixed bed intermittence or continous way Gas-making Furnace; It mainly acts on is to reduce thermal radiation; Prevent that raw material Jiao or the coal floor height temperature molten salt that in gasification, gasifies is bonded on the furnace wall, avoid producing hanging and protect, guarantee working of a furnace steady running; Simultaneously soft water absorbs gasification layer heat and produces a part LP steam in the chuck, and LP steam can be used by oneself after overheated or supplied outward.This traditional chuck can only be worked under 0.1MPa pressure, 104-133 ℃ temperature.Because dividing the rampart portion of gasification layer in the Gas-making Furnace, the effect of water wall forms 80mm-100mm left and right sides cold zone; Not only reduce the due sectional area of burner hearth but also caused raw material not exclusively to gasify; Carbon residue increases in the lime-ash, and the low-grade saturation steam steam-water separation effect that chuck produces is poor, and water phenomenon is serious; If without bakingout process, use value is low.
For gas making, perfect condition is that heat preferably all is stored in the fuel bed, and temperature is high more, and gasification intensity is high more, and cold-wall effect is few, and only otherwise scab, the gasification layer should remain high temperature, and the gas prodn amount is big like this, and lime-ash carbon residue is low, and raw material consumption is low.The steam of by-product is few more good more, is great waste with raw material Jiao or coal byproduct steam to energy, and the task of gas making is to give birth to be coal gas rather than steam.At present, part enterprise reduces thermosteresis in order to improve inner wall temperature; Adopting the method that improves vapor pressure, is limited but pressurize improves temperature, and the chuck pressure improves; Equipment material and welding technique just need upgrading, and main equipment just needs to change, and cost will sharply increase.
The utility model content
The purpose of the utility model provides a kind of Gas-making Furnace chuck fused salt heat exchanging system, and this system can significantly improve the Gas-making Furnace inner wall temperature, alleviates the cold-wall effect of Gas-making Furnace.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme: comprise Gas-making Furnace, high-temperature zone, Gas-making Furnace body of heater bottom is provided with jacket boiler; This system also comprises the fused salt storage tank; The outlet of fused salt storage tank links to each other with the import of pump for liquid salts, and the fused salt pump outlet links to each other with the import of jacket boiler, and the outlet of jacket boiler links to each other with the import of interchanger; The outlet of interchanger links to each other with the import of pump for liquid salts, and the medium in the described fused salt storage tank is liquid fused salt.
The fused salt pump outlet of the utility model is provided with the by-pass line that is communicated with the fused salt storage tank with the pipeline between the jacket boiler, and by-pass line is provided with first valve.
The pump for liquid salts of the utility model comprises first, second pump for liquid salts that parallel connection is provided with.
The import and export place of first pump for liquid salts of the utility model is provided with the 4th, the 5th valve respectively, and the import and export place of second pump for liquid salts is provided with the 6th, the 7th valve respectively.
The import of the fused salt storage tank of the utility model links to each other with the fused salt melting channel.
The exit of the fused salt melting channel of the utility model is provided with second valve, and the exit of fused salt storage tank is provided with the 3rd valve.
Be equipped with steam heating tube and drip pipe in fused salt melting channel of the utility model and the fused salt storage tank.
The import and export place of the interchanger of the utility model is provided with the 8th, the 9th valve respectively.
Can be known that by technique scheme the liquid fused salt in the utility model fused salt storage tank is through pump for liquid salts circulation, delivering in the Gas-making Furnace jacket boiler further that circulation heats up again, through interchanger heating soft water, produce saturation steam again, steam is again through overheated personal or outer confession.Because the fusing point of fused salt and boiling point are all high than soft water, and can under lower operating pressure, obtain higher working temperature; So adopt fused salt to replace soft water as heat-transfer medium, the temperature in the jacket boiler is improved, reduced the heat that thermal medium is taken away in the jacket boiler like this; Loss reduces in the Gas-making Furnace, has improved gasification efficiency, has improved Gas-making Furnace gas yield and quality; Reduce the consumption of gasified raw material, significantly improved the cold-wall effect of Gas-making Furnace jacket boiler.
Description of drawings
Fig. 1 is the system architecture synoptic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 1 a kind of Gas-making Furnace chuck fused salt heat exchanging system comprises Gas-making Furnace 1, and high-temperature zone, Gas-making Furnace 1 body of heater bottom is provided with jacket boiler 2; This system also comprises fused salt storage tank 3; The outlet of fused salt storage tank 3 links to each other with the import of pump for liquid salts, and the fused salt pump outlet links to each other with the import of jacket boiler 2, and the outlet of jacket boiler 2 links to each other with the import of interchanger 4; The outlet of interchanger 4 links to each other with the import of pump for liquid salts, and the medium in the fused salt storage tank 3 is liquid fused salt.The exit of fused salt melting channel 5 is provided with second valve 62; The exit of fused salt storage tank 3 is provided with the 3rd valve 63; The import and export place of first pump for liquid salts 7 is provided with the 4th, the 5th valve 64,65 respectively; The import and export place of second pump for liquid salts 8 is provided with the 6th, the 7th valve 66,67 respectively, and the import and export place of interchanger 4 is provided with the 8th, the 9th valve 68,69 respectively.
