4, utilize the oxygen-enriched atmosphere in oxygenerator guarantee producer gas generator, then pass through the effect of preheating of air stove and gas blower, both improve the furnace temperature of producer gas generator, and turn improved the CO content in coal gas.
5, substantially occur without waste residue in product, environment protecting is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, the system of blast furnace oxygen hot method melting calcium carbide in a kind of PVC production process, comprise producer gas generator, oxygenerator, blending bunker, coal powder injection device, fly-ash separator, preheating of air stove, gas blower, gas chamber and calcium carbide storehouse etc., the oxygen outlet of oxygenerator connects the oxygen intake of producer gas generator and the oxygen intake of preheating of air stove by oxygen storage tank, the nitrogen outlet of oxygenerator connects nitrogen storage tank, and nitrogen storage tank connects nitrogenous fertilizer preparation system.The outlet of blending bunker connects the feed(raw material)inlet of producer gas generator, the pci port of coal powder injection device connects the fuel inlet of producer gas generator, the entrance of fly-ash separator connects the waste gas outlet of producer gas generator, the pneumatic outlet of fly-ash separator connects the entrance of gas chamber, the dust outlet of fly-ash separator connects the material inlet of preheating of air stove, the pneumatic outlet of preheating of air stove connects the heating gas inlet of producer gas generator, and the outlet of gas blower connects the gas inlet of preheating of air stove; The entrance in calcium carbide storehouse connects the bottoms material outlet of producer gas generator.
The working process of native system is as follows:
Batching enters into producer gas generator by blending bunker, utilizes coal powder injection device to spray into coal dust, and utilizes oxygenerator to send into oxygen to producer gas generator and preheating of air stove, and under high-temperature low-pressure, coal dust generates calcium carbide and ferrosilicon with batching melting.Due to the oxygen-enriched environment of producer gas generator, containing the CO of 55%-95% in the waste coal gas that reaction produces.Every melting one ton of purity is the calcium carbide of 80%, produces coal gas (CO is 55%-95%) 6000-2600m
3, the methyl alcohol of about 4.5 tons can be produced.Oxygen enrichment had both improved the CO content that furnace temperature turn improves coal gas, and process in waste gas reduster, heat is transmitted back to preheating of air stove with dust, and then was sent in producer gas generator and again utilizes.Coal gas after dedusting is sent to gas chamber, for Coal Chemical Industry or clean electric power generation, also adds smelly as domestic gas by device for adding odor.This process change various producer gas generator process energy consumption was large in the past, waste residue is many situation, can reduce energy consumption greatly, cost-saving, is beneficial to environment protection simultaneously.
