Summary of the invention
Utility model object: the industrial tail gas treatment process device that a kind of mechanical strength is high, vent gas treatment ability is strong is provided.
Technical scheme:
The industrial tail gas of carbon fibre-reinforced graphite of the present utility model is processed in complete equipment, according to processing flow sequence, the tail gas of industry first absorbs and evaporation through film-falling absorption tower, then through absorption and the regeneration discharge of packed tower, the cooling eventually passing cooling tower be separated.
In film-falling absorption tower, the position contacted with tail gas is that full carbon fibre-reinforced graphite is made (can tolerate inner very large gas pressure); The inwall at the position contacted with solution is that graphite or carbon fibre-reinforced graphite make (corrosion-resistant, mechanical strength is high), and outside wall surface is that corrosion resistant plate is made (inwall can tolerate corrosion and the liquid-level pressure of solution, and outer wall is easy to shaping manufacture, and cost is lower).Film-falling absorption tower top has inlet exhaust gas, absorbs water inlet, (diameter on filter is between a large amount of filter openings of 1-3mm filter in the middle part of film-falling absorption tower, gas and liquid separation, both be convenient to liquid flow rapidly into, prevent from again liquid from being formed on foam to gush), film-falling absorption tower bottom is connected with solution tank.Higher than the place of liquid level, there is organic gas outlet in solution tank, in solution tank, be connected with solution heating and thermocirculator lower than liquid level place.The solution temperature of thermal cycle is preferably 50-80 DEG C, and the organic gas making solubility larger is by water solution absorption, and the abundant spillage solution of the gas that most of solubility is lower emits.
In packed tower, the position contacted with gas is that full carbon fibre-reinforced graphite is made, gas enters packed tower from bottom, packed tower inside is divided into three layers from lower to upper, successively by lower packing layer, cooler pan tube layer, upper packing layer, cooling water absorbs gas heat and becomes hot water or steam discharge in cooling coil, cleaning of off-gas (non-toxic gas such as residual carbon dioxide, nitrogen) is discharged in air finally by the evacuation port above packed tower, separately have partial organic substances be condensed (preferably lower than 10 DEG C) formed afterwards solution flow into cooling tower.Filler in packed tower is activated carbon fiber, and this filler effectively can adsorb organic gas.
In cooling tower, the internal face contacted with solution is that graphite or carbon fibre-reinforced graphite are made, and outside wall surface is that corrosion resistant plate is made.In cooling tower, solution chilling temperature is lower than-10 DEG C, and most of organic substance is liquefied, and the organic substance of liquefaction carries out chromatography in cooling tower.
Beneficial effect:
The function ratio of the utility model process tail gas is comparatively comprehensive, and can fully absorb organic substance soluble in water, can discharge again and reclaim out multiple organic gas composition not soluble in water, safe gas can directly be discharged in air simultaneously.Tail gas treating function is comprehensive, and process is relatively thoroughly cleaner, reclaims useful component, saves material.Simultaneously the housing of equipment or the mechanical strength of inwall higher, corrosion resistance is better.The utility model is applicable to recycling and the purified treatment of multiple gases tail gas.
