Abstract
The invention discloses a heat supply system using straws as raw materials in the caustic soda processing, which comprises a screw conveyer, a dry distillation and gasification furnace, a gas-solid cyclone separator, a cooling device, a gas-liquid separator, a primary filter, a secondary filter, a roots blower and a gas storage cabinet which are connected sequentially, wherein the input end of the cooling device is connected with a gas phase outlet of the gas-solid cyclone separator; the input end of the primary filter is connected with a gas phase outlet of the gas-liquid separator; and an outlet of the gas storage cabinet is connected into a caustic soda pot kiln hearth through a fuel gas conveying and distributing pipe network. The heat supply system for the caustic soda pot kiln hearth in an alkali making system can utilize dry distillation of the straws to generate clear fuel gas so as to realize environmental-friendly production, saves energy and prolongs the service life of subsequent equipment.
Description
Technical field
The present invention relates to a kind of heating system, relate in particular to a kind of heating system that is used for making alkali system caustic soda pot kiln kitchen range.
Background technology
In the production of caustic soda system, the traditional producer gas generator of the general employing of the heating system of caustic soda pot kiln kitchen range can be a coal gas with the raw coal solid fuel conversion continuously, is transported in other cooking stoves and burns at present.
But existing hand burns semi-gas furnace or simple and easy gas furnace (being commonly called as vapourizing furnace), though can heat exchange do work, because of artificial periodically coal, not only labour intensity is big.And destroyed the boiler combustion operating mode, can not continuous heat supply work, serious is one burns one more clearly, intermitten service, and boiler adaptation coal is single, can only burn fat coal, can not burning inferior coal, cause volume of smoke to be discharged into and cause serious atmospheric pollution in the air, environmental protection is not up to standard, wastes energy.
Summary of the invention
The invention provides a kind of heating system that is used for making alkali system caustic soda pot kiln kitchen range, utilize the stalk destructive distillation to produce the combustion gas of cleaning, realized environmental protection production.
Utilize the heating system of stalk in a kind of caustic soda processing for raw material, comprise the worm conveyor, destructive gasifying stove, gas-solid cyclone separator, water cooler, gas-liquid separator, grade one filter, secondary filter, roots blower and the gas storage holder that connect successively, the gaseous phase outlet of the input termination gas-solid cyclone separator of wherein said water cooler, the gaseous phase outlet of the input termination gas-liquid separator of grade one filter, the gas storage holder outlet inserts caustic soda pot kiln kitchen range by the gas transmission and distribution pipe network.
When heating system of the present invention is used, at first the raw material straw is rolled into particle, add less water, send into the destructive gasifying stove with worm conveyor, in the destructive gasifying stove, straw is under the insufficient condition of oxygen, and destructive distillation, pyrolysis, gasification are reduced into C
mH
n, CO, H
2Etc. flammable mixed gas.
The flammable mixed gas that produces is removed bulk solid phase foreign material through gas-solid cyclone separator, and gas phase enters water cooler reduction temperature, dwindles the volume of gas.
Cooled flammable mixed gas is by H
2, CO, CO
2, CH
4, C
2, C
3And the higher hydrocarbon composition, also have NH simultaneously
3, H
2S, ash and tar, thereby the purification that just needs to work off one's feeling vent one's spleen is used to supply with subsequent handling.The present invention feeds gas-liquid separator with cooled flammable mixed gas and removes water and tar in the flammable mixed gas, flammable mixed gas after dehydration and the decoking enters grade one filter successively and secondary filter carries out coarse filtration and finly filtration, makes pure combustible gas (said process is called gas-purification) behind the two-stage filtration.One-level is filtered and can be selected for use the corn ear particle as filtrate, and cascade filtration can select for use the fiber grain of 2mm～3mm particle diameter as filtrate.Pure combustible gas can guarantee that follow-up equipment can not cause its erosion corrosion because of the existence of impurity
Pure combustible gas is sent into gas storage holder after the roots blower pressurization, by the pipe network of gas transmission and distribution system, fuel gas supply is concentrated in the system alkali system caustic soda pot kiln kitchen range again, produces heat through burning and carries out the processing of caustic soda.
If no specified otherwise, the assembly of elements in the heating system of the present invention can adopt prior art.
The present invention is used for making the combustion gas that the heating system of alkali system caustic soda pot kiln kitchen range can utilize the stalk destructive distillation to produce cleaning, realizes environmental protection production, not only save energy but also prolonged work-ing life of follow-up equipment.

Embodiment
Referring to Fig. 1, utilize the heating system of stalk in a kind of caustic soda processing of the present invention for raw material, comprise the worm conveyor, destructive gasifying stove, gas-solid cyclone separator, water cooler, gas-liquid separator, grade one filter, secondary filter, roots blower and the gas storage holder that connect successively, the gaseous phase outlet of the input termination gas-solid cyclone separator of wherein said water cooler, the gaseous phase outlet of the input termination gas-liquid separator of grade one filter, the gas storage holder outlet inserts caustic soda pot kiln kitchen range by the gas transmission and distribution pipe network.
During use, at first the raw material straw is rolled into particle, add less water, send into the destructive gasifying stove with worm conveyor, in the destructive gasifying stove, straw is under the insufficient condition of oxygen, and destructive distillation, pyrolysis, gasification are reduced into C
mH
n, CO, H
2Etc. flammable mixed gas.
The flammable mixed gas that produces is removed bulk solid phase foreign material through gas-solid cyclone separator, and gas phase enters water cooler reduction temperature, dwindle the volume of gas, cooled flammable mixed gas enters grade one filter successively and secondary filter carries out coarse filtration and finly filtration, makes pure combustible gas (said process is called gas-purification) behind the two-stage filtration.One-level is filtered and can be selected for use the corn ear particle as filtrate, and cascade filtration can select for use the fiber grain of 2mm～3mm particle diameter as filtrate.
Pure combustible gas is sent into gas storage holder after the roots blower pressurization, pipe network by gas transmission and distribution system again, fuel gas supply is concentrated in the system alkali system caustic soda pot kiln kitchen range, produce heat through burning and carry out the processing of caustic soda, if no specified otherwise, the assembly of elements in the heating system of the present invention can adopt prior art.
The combustion gas that heating system of the present invention can utilize the stalk destructive distillation to produce cleaning realizes environmental protection production, not only save energy but also prolonged work-ing life of follow-up equipment.
