Abstract
The invention discloses a recovery processing method for phenol water of a gas furnace. The method comprises the following steps of: (1) collecting the phenol water; (2) adding 0.2 to 0.8kg of cleanser essence and 2.0 to 3.0kg of scale remover into each ton of phenol water and precipitating; (3) filtering tar and impurities in the phenol water; (4) heating the phenol water and vaporizing the phenol water into steam; and (5) adding the phenol water steam into a gas producer to react with coal. The recovery processing method for the phenol water of the gas furnace provided by the invention can not only save cost but also reduce environmental pollution by recycling the phenol water of the gas furnace.
Description
Technical field
The present invention relates to the phenol water disposal field, relate in particular to a kind of recovery processing method for phenol water of gas furnace.
Background technology
Can be in the process of gas furnace generation coal gas with the generation of phenol water, nearly 5 tons～6 tons of the phenol water of gas station generation every day, the phenol shipwreck is in processing, and intractability is bigger, and environment is caused bigger harm.The treatment process of general phenol water is phenol water atomisation, utilizes burning of coal to burn, and such treatment process need expend a large amount of water, produces a large amount of waste gas, and economic cost is 350 yuan/ton, not only cost of idleness but also contaminate environment.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that remedies prior art, and purpose is to provide a kind of recovery processing method for phenol water of gas furnace, with the phenol water recycling of gas furnace, both can save cost, can reduce the pollution to environment again.
For solving above technical problem, technical scheme of the present invention is that a kind of recovery processing method for phenol water of gas furnace comprises the steps:
(1) collects phenol water;
(2) phenol water per ton adds liquid detergent 0.2kg～0.8kg, scale remover 2.0kg～3.0kg, precipitation;
(3) tar and the impurity in the filtration phenol water;
(4) heating phenol water changes into vaporous with the phenol aqueous vapor;
(5) vaporish phenol water is joined in the producer gas generator, react with coal.
Preferably, phenol water per ton adds liquid detergent 0.4kg～0.6kg, scale remover 2.3kg～2.7kg in the step (2).
Preferably, tar in the step (3) in the phenol water and impurity filter by phenol water filtration case, are provided with the fine sand filtering layer in the described phenol water filtration case, are equipped with the straw mat filtering layer on the described fine sand filtering layer.
Preferably, the thickness of described straw mat filtering layer is 300cm～500cm.
Preferably, be provided with two-layer fine sand filtering layer in the described phenol water filtration case, be equipped with the straw mat filtering layer respectively on the described fine sand filtering layer.
Preferably, utilize the water-cooled case waste heat heating phenol water of producer gas generator in the step (4).
Preferably, described water-cooled case waste heat supply temperature is controlled at 600 ℃～700 ℃.
Compared with prior art, the recovery processing method for phenol water of gas furnace provided by the invention, after the phenol water process precipitation and filtration treatment of collecting, become pure liquid after removing contained tar and impurity, get back in the producer gas generator after phenol water heating is vaporized into vaporous, produce coal gas with coal reaction, both water saving can reduce the pollution to environment again.
Especially, the recovery processing method for phenol water of gas furnace provided by the invention utilizes the water-cooled case waste heat of producer gas generator to heat phenol water in the step (4), utilizes the equipment heating phenol water of producer gas generator, and further save energy cuts down the consumption of energy.
