In the description of the present invention, it should be noted that term " " center ", " on ", " under ", " left side ",.It is " right side ", " perpendicular Directly ", the orientation of the instructions such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only The utility model must have specific with the device or element for simplifying description rather than instruction or hint meaning for ease of description Orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally Connection;Can be mechanical connection or electrical connection;It can be directly connected, can also be indirectly connected by intermediary, It can be the connection inside two elements.For the ordinary skill in the art, can above-mentioned art be understood with concrete condition Concrete meaning of the language in the utility model.
With reference to Fig. 1, the recycling of desorption steam organic matter and fixed gas purifying integration device of the utility model include condensation The subsequent purification device in 2 downstream of device 2 and condensing unit.
Condensing unit is equipped with fluid inlet 1, i.e. exhaust gas inlet, condensing unit is internally provided with gas passage, leads to for exhaust gas It crosses, is additionally provided with gravity assisted heat pipe as heat transfer unit, gravity assisted heat pipe is in direct contact with gas passage, and high-temp waste gas passes through heat exchanger Heat absorbing side releases heat, which is quickly transmitted to the cold side of heat exchanger through heat pipe, and exhaust gas temperature is reduced.Cooling water leads to Heat is absorbed during the cold side for crossing heat exchanger, the heat of hot water is the thermal energy for recycling high-temperature gas, is achieved in waste heat and returns The purpose of receipts.After exhaust gas temperature declines simultaneously, the partial organic substances matter in exhaust gas is condensed and is removed;Condensate liquid enters condensation The oil trap 21 of 2 lower section of device, can concentrate separating-purifying, so as to recycle the organic matter that condensation obtains.Condensing unit 2 leads in gas Road downstream is equipped with fluid outlet 22, and the exhaust gas after cooling is sent to the subsequent purification device in downstream.
Sensing TT&C system can be set, and the cooling effect, recuperation of heat effect, organic substance yield to exhaust gas carry out real When monitor and record, and feed back to PLC control system, the intelligent control for product provides data.
Subsequent purification bottom of device is catch box 6, and catch box 6 is equipped with air inlet, and air inlet is connected with fluid outlet 22, 6 top of catch box is at least partly open, also, is purifier housing 8 at the top of catch box, in the accommodating cavity in housing 8, by Under it is supreme successively be equipped with spray washing device 3, ultraviolet photolysis device 4, demister 5.Exhaust gas after cooling passes through catch box liquid Space above face enters housing 8.
As shown in Figure 1, spray washing device includes packing area 31, pump 9 and pipeline, pipeline includes external pipe 33 and interior Portion's pipeline 32, internal pipeline 32 are located at the top of packing area 31.The nozzle of internal pipeline 32 can be one or more, and direction Packing area 31.Each nozzle has gap with 31 surface of packing area, in favor of expanding spray area.Pump connection catch box 6, will collect Liquid in liquid case 6 is pumped by external pipe 33, internal pipeline 32 to nozzle.
Filler is high-efficient purification filler, and ejecting liquid sprays at the top of filler in spray washing device, the table of filler wetting Face becomes the mass transfer surfaces that gas-liquid continuously contacts with, and the organic waste in removal gas is absorbed using double films effect between gas-liquid two-phase Gas.Meanwhile spray washing fluid is cooled down twice exhaust gas.Spray washing device sprays (i.e. for cross-flow in the utility model Ejecting liquid flowing is opposite with gas flow direction).Spray washing fluid is flowed down from packing area 31, falls into the catch box of lower section It is interior, realize cycle.
The spray washing device is connected with PLC control system, is controlled by PLC control system.
Gas after spray washing enters ultraviolet photolysis device, and ultraviolet photolysis device includes ultraviolet light generator 41 (such as Electrodeless UV lamp pipe), 185nm and 254nm ultraviolet lights can be sent out, can be cracked using the high-energy of 185 nanometers of short wave ultraviolets Organic exhaust gas.
Ultraviolet photolysis device can also include photocatalyst of titanium dioxide 42, it is preferable that have at least one or more ultraviolet light Generator 41 is located at 42 lower section of photocatalyst bed.It is cracked in this way, organic exhaust gas first passes around ultraviolet light.Photocatalyst bed 42 Can be that multilayer is set, surface is equipped with one or more ultraviolet light generators 41 above and/or under each layer of photocatalyst bed 41, utilizes 254 nanometer ultraviolet rays irradiation titanium deoxide catalyst generates the active secondary oxidant such as hydroxyl to aoxidize organic exhaust gas.It is organic Under the synergistic effect of photocatalyst and ultraviolet light oxygenolysis persistently occurs for exhaust gas, ultimately generates carbon dioxide and water.

The demister 5 uses baffle type mist eliminator, including baffle plate arranged side by side.
It is for gas to pass through that gap is formed between baffle plate, when the gap between the gas containing water mist enters baffle plate, Since the inertial impaction of gas acts on, water mist collides with baffle plate and is attached to surface.The diffusion of baffling plate surface water mist Water mist is made to form larger drop and moves forward to baffle plate turning with air-flow with gravitational settling, due to turn to centrifugal force and The surface tension of rubbing action, suction-operated and liquid with baffle plate so that drop is increasing, until the drop gathered is big To its own generation gravity be more than gas climbing power and surface tension of liquid resultant force when, drop is divided from baffling plate surface From getting off.
Baffle plate can be at least partially corrugated sheet, can also be that at least part surface is equipped with raised baffle or protrusion Texture or the two exist simultaneously, and this being folded to structure increases the chance that water mist is captured more, and the water mist not being removed is under One turning is captured through phase same-action, and such repeated action greatly improves efficiency.
Exhaust gas after demisting is discharged by the gas outlet 7 at 8 top of housing.
Catch box 6 includes water tank, liquid level gauge, water supply solenoid valve, drain solenoid valve and (is equipped with overflow port, lower water at upper water level Sewage draining exit is equipped at position).The fluid level controller, water supply solenoid valve, drain solenoid valve are connected with PLC control system.Liquid collecting There can also be filtering and cleaning device in case 6.
In catch box fluid low or it is excessively high when, liquid level gauge sends a signal to PLC control system, PLC control system moisturizing Solenoid valve, drain solenoid valve work.
Finally it should be noted that:The above various embodiments is only to illustrate the technical solution of the utility model rather than it is limited System;Although the utility model is described in detail with reference to foregoing embodiments, those of ordinary skill in the art should Understand:It can still modify to the technical solution recorded in foregoing embodiments either to which part or whole Technical characteristic carries out equivalent replacement;And these modifications or replacement, this practicality that it does not separate the essence of the corresponding technical solution are new The range of each embodiment technical solution of type.
