Compared with prior art, the present invention has technique effect beneficial below：
The device of processing semi-coke wastewater disclosed by the invention, vapor is passed through into stripping room, and in the side of stripping room
Sidewall bottom setting water purifying chamber, the interface for stripping room and water purifying chamber are equipped with molecular sieve, and stripping interior is additionally provided with spreads dirt for dividing
The flow distribution plate of water, four pieces of flow distribution plates are staggered two-by-two on the inner wall of stripping room.Semi-coke wastewater is placed in stripping room and is carried out
Processing, while it being passed through vapor into stripping room, several flow distribution plates can effectively expand the contact area of sewage and water vapour,
Help to enhance the volatile gas such as ammonia and phenols in semi-coke wastewater to separate from sewage, and overflow into water vapour, takes off
In addition to the sewage of escaping gas is handled using molecular sieve, impurity can be removed, water purification is eventually converted into.Contain volatility gas
The steam of body is then collected by condenser in condensation water tank, to recycle.The apparatus structure is simple, easy to use, energy saving
The substances such as the phenols in semi-coke wastewater and ammonia nitrogen can be effectively treated in environmental protection, at low cost.
