Phenol water treatment technique and device for gas furnace

Abstract

The invention discloses a phenol water treatment technology of gas furnace and device in waste water disposal domain, which is characterized by the following: proceeding heat exchange with air and lower branch gas; touching with atomized phenol water; evaporating the phenol in the phenol water; burning the phenol; making the device comprise two-section coal-gas producer and phenol water pool; equipping with cyclone saturation tower, shell-and-tube heat exchanger, air pump and phenol water pump. This craft and device possess the advantages of energy-saving and environment protection, which can diminish the pollution for environment.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and in particular relates to a phenol water treatment process and device for a gas furnace. Background technique [0002] The treatment of phenol-containing wastewater from gas stations has always been a matter of special concern to coal gasification professionals. At present, the commonly used method is to use incinerators for incineration, which can completely decompose phenol water into harmless water and carbon dioxide. Although this method is simple and effective , but burning 1kg of phenol water needs to consume about 0.12kg of tar or 0.7Nm 3 Coal gas, a two-stage gasifier with a diameter of 3.2m produces about 4000kg of phenol water a day, and needs to consume 480kg of tar or 2800Nm 3 Gas, enterprises have to bear high processing costs for this, and at the same time consume a lot of energy. In the current situation of expensive energy, the burden on enterprises is even heavier; anothe...
