Content of the invention
Content of the invention:
Goal of the invention: provide a kind of high mechanical strength, vent gas treatment ability strong industrial tail gas handling process device.
Technical scheme:
The industrial tail gas of the carbon fibre-reinforced graphite of the present invention process in complete set of equipments, according to processing technological flow order, work
The tail gas of industry first passes through film-falling absorption tower and absorbs and evaporate, and is then passed through absorption and the regeneration discharge of packed tower, eventually passes cold
But the cooling of tower and separation.
In film-falling absorption tower, the position contacting with tail gas is that full carbon fibre-reinforced graphite is made；The portion contacting with solution
The inwall of position is graphite or carbon fibre-reinforced graphite is made (corrosion-resistant, high mechanical strength), and outside wall surface is corrosion resistant plate system
Become (inwall is resistant to corrosion and the liquid-level pressure of solution, and outer wall is easy to molding manufacture, and cost is relatively low).Film-falling absorption tower top
There are inlet exhaust gas, absorb water inlet, (diameter on screen plate is a large amount of between 1-3mm screen plate in the middle part of film-falling absorption tower
Filter opening, gas and liquid separation, be both easy to liquid and had flowed rapidly into, and prevented liquid from being formed again and gushed on foam), film-falling absorption tower bottom
It is connected with solution tank.The place in solution tank being higher than liquid level has organic gas outlet, is less than and is connected with liquid level in solution tank
Solution heating and thermocirculator.The solution temperature of thermal cycle is preferably 50-80 DEG C so that the larger organic gas quilt of dissolubility
Water dissolution absorbs, and the abundant spillage solution of the relatively low gas of most of dissolubility emits.
In packed tower, the position contacting with gas is that full carbon fibre-reinforced graphite is made, and gas enters filler from bottom
Tower, is divided into three layers from lower to upper inside packed tower, pass sequentially through lower packing layer, cooler pan tube layer, upper packing layer, cooling water is cold
But absorb gas heat in coil pipe and become hot water or steam and discharge, cleaned tail gas (the no poison such as residual carbon dioxide, nitrogen
Body) it is discharged in air finally by the evacuation port above packed tower, separately there are partial organic substances to be condensed after (preferably shorter than 10 DEG C)
Form solution and flow into cooling tower.Filler in packed tower is activated carbon fiber, and this filler being capable of active adsorption organic gas.
In cooling tower, the internal face contacting with solution is graphite or carbon fibre-reinforced graphite is made, and outside wall surface is not
