Description of the drawings
Fig. 1 is the utility model device flowage structure schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment illustrates the utility model.
As shown in figure 1, a kind of exhaust treatment system of short rayon fiber dryer, including the tail gas air inlet pipe being sequentially connected,
Box gas-gas heat exchanger, high-pressure electrostatic grease dirt collector, spiral board scrubbing tower and blower fan, the system also includes controller, institute
State box gas-gas heat exchanger, high-pressure electrostatic grease dirt collector and spiral board scrubbing tower to be connected with controller respectively, the spiral board
Scrubbing tower is provided with two and is connected in parallel, and tail gas filtering dress is provided between the tail gas air inlet pipe and box gas-gas heat exchanger
Put.The course of work of the system is as follows：
Drying tail gas is passed through by box gas-gas heat exchanger, and after heat exchange, drying the temperature of tail gas reduces, in drying tail gas
Part oil mist particles can condense the surface for being attached to heat exchanger coils, and the oil drain out for then flowing to heat exchanger is discharged.
High-pressure electrostatic grease dirt collector is entered through the drying tail gas of box gas-gas heat exchanger process, its filter is by big
Grain mist of oil and the intercepted separation of water smoke, the mist of oil containing fine particle and water smoke enter charging area, and tail gas is by containing a large amount of ions
During with the space of electronics, ion and electrons are attached on mist of oil and water smoke, and the particle for adhering to anion and electronics is negatively charged, attached
The particle positively charged of cation.Charged mist of oil and water fog particle is entered after collecting region, in the presence of high-voltage electrostatic field, to
Opposite polarity pole plate motion, collides and be captured on battery lead plate.When the mist of oil and water fog particle on pole plate run up to it is a certain amount of
When, profit pools the oil collecting zone that drop flows to bottom, and is reclaimed by the sewage draining exit discharge of bottom.
It is captured recovery through above two stages for the treatment of animal oil major part, but also sub-fraction oil mist particles are with tail
Rearward, in order to reduce being vented the harm to environment, needs are further processed tail gas air-flow.When liquid enters spiral board
Scrubbing tower, then along certain angle obliquely through the gap between plate, in eddy flow state, by the liquid rotation direction tower wall on plate,
Into plate area.Gap of the gas along between certain oblique threading piece of angle, forms eddy flow state, by the liquid rotation direction tower on plate
Wall, so as to carry out the mass transfer between gas-liquid.The tangent line such as dust or mist of oil enters bottom of towe, screw upwards, because of the guiding of column plate
Act on and strengthen rotation.Dust nebulizes the liquid dispersion that step by step tray is flowed down on column plate, and the contact area between gas-liquid is big, waste gas
In mist of oil adhered to by water smoke, by centrifugal action be thrown to tower wall with liquid discharge.And through tertiary treatment tail gas from tail gas
Discharge pipe discharge system.
