Abstract

The utility model discloses an integrated wet oxidized waste water processor which belongs to the equipment for industrial waste water treatment, particularly the equipment used for processing the industrial waste water under the condition of high temperature and high pressure. The structure of the device is that the integrated wet oxidized waste water processor is composed of a preheating device, a heater and a fixed bed reactor which are orderly connected from up to down in the same heat-insulating container, wherein the bottom of the preheating device is provided with a waste water inlet, and one-way valves for temperature and pressure control are arranged at the connecting positions between the preheating device and the heater and between the heater and the reactor. A high-temperature water outlet for processed water arranged at the top of the reactor is connected with a water inlet of a heat-exchanging pipe using the reaction heat, the heat-exchanging pipe is arranged in the preheating device, and a water outlet of the heat-exchanging pipe is an air outlet for the processed water. The processor integrates the three sets of devices which are arranged in dispersion in the same heat-insulating container, the reuse of various heat energy is realized and the valve for the temperature and pressure control between the device can be adjusted at any time according to the operational conditions of the devices. The continuous production is ensured, and the processing capacity and the utilization rate of the device are improved.

Description

Integral type wet oxidation wastewater treatment equipment

Affiliated technical field

The utility model belongs to Industrial Wastewater Treatment equipment, particularly handles the equipment of trade effluent under high-temperature and high-pressure conditions.

Background technology

The technology that adopts wet oxidation process to handle trade effluent is in recent years adopted by more and more enterprises, this method for COD concentration at the high density of 25000-200000mg/L, poisonous, deleterious organic industrial sewage, the waste water that can't adopt traditional water technology (biological example chemical technology) to handle has good suitability, but, there are shortcomings such as pipe network complexity, energy consumption height and interruption production for the steam water interface that obtains High Temperature High Pressure usually needs many complete equipments.

Summary of the invention

The purpose of this utility model provide a kind of can be to heat pressurization and carry out the technical scheme of the integration apparatus of oxidation of steam water interface.

The technical solution of the utility model is, integral type wet oxidation wastewater treatment equipment, its structure is: be made up of the preheater, well heater, the fixed-bed reactor that connect successively from bottom to top that are installed in the same insulating container, the waste water import is equipped with in the preheater bottom, temperature, pressure control check valve is equipped with in preheater and well heater, well heater and reactor junction, is positioned at that the high-temperature water outlet connects the water-in of handling the back water pipe and leading to the utilization of Heat of Reaction heat transfer tube of preheater behind the treating water of reactor head, the water outlet of this interchanger is moisture outlet after handling.

Described well heater is equipped with the high-temperature steam heat transfer tube, and the afterheat steam of this heat transfer tube exports the afterheat steam import of leading to the waste heat heat transfer tube that is installed in the preheater through the afterheat steam pipe.

Three complete equipments that the utility model will disperse to install are contained in the same insulating container, in preheater, be provided with utilization of Heat of Reaction heat transfer tube and afterheat heat exchanger, can make full use of the reaction heat and the waste heat of high temperature and high pressure steam after the well heater heat exchange that produce in the oxidizing reaction, realize the utilization again of various heat energy preferably, because organic oxidation is thermopositive reaction, organic concentration in waste water is high to a certain degree (it is generally acknowledged that COD is greater than 70000mg/L), the heat that reaction takes place can be kept the needs of operation, the unloading phase of except that system, do not need to provide in addition energy.Temperature, pressure control valve between the equipment can be regulated at any time according to equipment running condition, guarantees continuous production, improves the processing power and the utilization ratio of equipment.
