Description
Technical Field
The invention belongs to the technical field of solid waste treatment, and particularly relates to a nitrogen making device for a solid waste treatment system.
Background
The oil field sludge in the solid waste is also a key project to be treated, the oil-containing sludge occupies a large amount of farmland due to large volume and poor dehydration effect, and pollutes surrounding soil, water and air, and the sludge contains a large amount of diseasesHeavy metals such as protobacteria, parasites (eggs), chromium, mercury and the like, and also contains a large amount of benzene series, phenols and other toxic substances with malodor and refractory toxic and harmful substances such as radioactive nuclide and the like. If the waste water is not effectively treated and discharged in time, the waste water can damage natural original ecology such as water, soil and trees and the like and seriously affect the health of surrounding people; in the prior art, the oil field sludge is placed in a plasma torch combustion chamber for combustion, the plasma torch instantly generates thousands of high temperature, the flame penetration is extremely strong, the movement direction and the stirring speed of a stirrer in the combustion chamber are continuously changed, and the oil-containing sludge is surrounded and roasted by flame at a moment. Opening a pneumatic valve to input nitrogen, cracking organic matters in the oily sludge in a high-temperature oxygen-free environment to generate C, H2、CO、H2O、CH4And combustible gas is collected by the exhaust port, water is filtered out, and the combustible gas is sent to a second combustion chamber for incineration treatment, so that pollution-free emission is realized, and harmful pathogenic bacteria can be directly killed at a high temperature.
The air compressor machine commonly used in the nitrogen generator generally adopts oil spout formula screw compressor, and some users can use oil-free screw compressor, or large-scale device can form a complete set and use centrifugal air compressor machine. In any type of compressor, when the compressed air is compressed and then cooled, the water content of the compressed air tends to be saturated. If the compressed air is cooled to 40 ℃ and is saturated with water, the absolute water content of the compressed air is 50.9g/m3This refers to the moisture content per cube contained in the air in the compressed state. For the pressure swing adsorption system, a large amount of moisture enters the molecular sieve, the molecular sieve can preferentially adsorb the moisture and cannot play a role in air separation, the strength of the molecular sieve can be greatly reduced, the pulverization of the molecular sieve is caused, and the failure of the system is further caused; for membrane separation systems, the same can cause failure of the membrane system due to the ingress of saturated, water-containing compressed air into the interior of the membrane fibers. Especially in the case of compressed air from oil injected screw compressors, moisture can entrain oil into the system, causing poisoning of the molecular sieve or unintended damage to the membrane fibers.
