Abstract
The utility model provides a system for treating waste water in production of dimethyl ether, belongs to the technical field of sewage treatment systems and also belongs to the field of improvement on the energy and environment technologies. The system is characterized by comprising a reaction kettle, a rectifying tower, a heat exchanger, an adjusting pool, an aeration machine, a microorganism treating tower, a sterilization reaction kettle, a daily water pool, methyl alcohol and dimethyl ether, wherein the methyl alcohol reacts in the reaction kettle by a catalyst to generate the dimethyl ether and the waste water; the waste water is rectified by the rectifying tower till the COD (Chemical Oxygen Demand) of organic matters in the rectified waste water is less than 200, the rectified waste water is heat-exchanged by the heat exchanger and then is discharged into the adjusting pool so as to enable the temperature of the waste water to be less than 42 DEG C, the waste water in the adjusting pool is conveyed to the microorganism treating tower, simultaneously the aeration machine is used for blowing air to the tower so as to enable the organic matters in the waste water to be decomposed under the action of microorganisms, and the waste water decomposed by the microorganism treating tower can enter the daily water pool directly and enter a circulating water system after passing through the sterilization reaction kettle.
Description
Technical field
The utility model relates to a kind of dimethyl ether production wastewater treatment system, belongs to Sewage treatment systems technical field, is also the field that belongs to energy and environment technological improvement.
Background technology
At present, dme (DME) is as a kind of important industrial chemicals, and purposes is very extensive, for example, as the propelling agent of aerosol, and refrigeration agent, fuel and methylating reagent etc.Purity is greater than 99.99% dme and can be used as narcotic and use, and purity is greater than 90% dme and can be used as town gas, liquefied gas and automobile fuel, and in industrial production, dme adopts the method for dewatering preparing dimethy ether conventionally.The method of existing dimethyl ether by methanol dehydration, principal feature is to be provided with methanol distillation column, by the method for rectifying, the methanol aqueous solution in dme tower bottom of rectifying tower is carried out to separation, the methyl alcohol of purifying wherein, and the methyl alcohol after purifying is returned and does raw material, moisture wherein (comprise and derive from the water that water that material benzenemethanol brings and dehydration reaction produce) is discharged system from methanol distillation column tower reactor, there is no so treated sewage owing to containing gas chromatography, environment is caused to serious pollution.
