Abstract
The invention discloses supercritical water treatment equipment which comprises a preheater, a reactor, a cooler and a gas-liquid separation tank; a liquid inlet is formed in the upper end of the preheater; one end of the liquid inlet is connected with a wastewater feed pump through a pressure control valve; the other end of the liquid inlet is communicated with an air compressor through another pressure control valve; the reactor is arranged at the lower end of the preheater; the cooler is arranged at the lower end of the reactor; the gas-liquid separation tank is fixedly connected with the cooler; a liquid outlet is formed in the bottom of the gas-liquid separation tank. Compared with the prior art, the supercritical water treatment equipment has the advantages of being reasonable in design, short in processing period, good in treatment effect, free of secondary pollution, small in reactor size and capable of realizing self-heating reaction; meanwhile, when the supercritical water treatment equipment runs, heat recovery can be realized, the energy consumption for treating a unit quantity of water is low, the running cost is low, and the market utilization value is excellent.
Description
Technical field
The invention belongs to technical field of chemical, be specifically related to a kind of supercritical water treatment equipment.
Background technology
Nowadays, environmental protection industry (epi) increasingly causes the attention of government, enterprise.Environmental protection equipment is varied, but, the most whole
For market, especially for high concentrated organic wastewater in water processes this field, long processing period, processing cost are high, set
The inconvenience that the problems such as standby floor space is wide are brought to enterprise is more and more obvious.
The COD that high concentrated organic wastewater generally refers to be discharged by industries such as papermaking, leather and food is at more than 2000mg/L
Waste water, even as high as several ten thousand or even hundreds of thousands mg/L had, comparatively speaking, BOD is relatively low, the ratio of a lot of waste water BOD Yu COD
Less than 0.3.This allows for high concentrated organic wastewater and is difficult by the tradition water treatment technology such as bioanalysis and processes.
For high concentrated organic wastewater, processing method conventional on Vehicles Collected from Market has oxidation-absorption method, burning method, absorption
The methods such as method, SBR process.These methods, processing equipment and unit floor space is wide, energy consumption is high, long processing period, operation cost
Height, often reduces treatment effeciency, makes troubles to enterprise and unit.
Summary of the invention
It is an object of the invention to provide a kind of supercritical water treatment equipment, mainly solve existing for prior art is highly concentrated
The problem that degree treatment of Organic Wastewater is difficult and processing cost is high.
For achieving the above object, the present invention provides following technical scheme: a kind of supercritical water treatment equipment, including preheating
Device, reactor, cooler and gas-liquid separating tank, the upper end of described preheater is provided with inlet, and one end of described inlet is passed through
Pressure-control valve connects with wastewater feed pump, and the other end of inlet is connected with air compressor by pressure-control valve, institute
Stating reactor and be arranged on the lower end of preheater, described cooler is arranged on the lower end of reactor, described gas-liquid separation groove and cooling
Device is fixing to be connected, and the bottom of described gas-liquid separation groove is provided with liquid outlet.
Preferably, described cooler is set to pyramidal structure.
The technique effect of the present invention and advantage: this supercritical water treatment equipment, compared with conventional art, the present invention designs conjunction
Reason, processes the cycle short, high treating effect, and non-secondary pollution produces, and reactor volume is little, can realize autothermal reaction；Meanwhile, this
When bright equipment runs, can carry out recuperation of heat, the energy consumption processing the unit water yield is low, and operating cost is relatively low, has good market
Value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1 preheater, 2 reactors, 3 coolers, 4 gas-liquid separation grooves, 5 inlets, 6 pressure-control valves, 7 waste water enter
Material pump, 8 air compressors, 9 liquid outlets.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The invention provides a kind of supercritical water treatment equipment as shown in Figure 1, including preheater 1, reactor 2, cooling
Device 3 and gas-liquid separating tank 4, the upper end of described preheater 3 is provided with inlet 5, and pressure-control valve is passed through in one end of described inlet 5
6 connect with wastewater feed pump 7, and the other end of inlet 5 is connected with air compressor 8 by pressure-control valve 6, described reaction
Device 2 is arranged on the lower end of preheater 1, and described cooler 3 is arranged on the lower end of reactor 2, and described cooler 3 is set to taper knot
Structure, described gas-liquid separation groove 4 is fixing with cooler 3 to be connected, and the bottom of described gas-liquid separation groove 4 is provided with liquid outlet 9.
Reaction principle: utilize the Oxidation of supercritical water that organic carbon is changed into CO2And H2O, sulfur, phosphorus and nitrogen-atoms divide
Do not change into sulfate, phosphate, nitrate anion and nitrite ion or nitrogen.Organic wastewater oxidation in supercritical water is anti-
Should be shown below:
Organic compound+O2 CO2+H2O；
Hetero atom in organic compound[O]Acid, inorganic salt compound；
Acid+NaOH inorganic salt；
The preparation of supercritical water: the present invention uses high pressure plunger rod that high concentrated organic wastewater is squeezed into supercritical water treatment
In the reaction cavity of equipment, cavity stops 60s, with supercritical water as medium, oxidation Decomposition Organic substance in homogeneous, then leads to
Water is got rid of by excess pressure balance, and COD clearance can reach 98%.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
