Description
Technical field
The utility model belongs to wood-based plate glue technical field, specially a kind of glue tail gas recycling system.
Background technique
Currently, Artificial Plate Adhesive manufacturing enterprise, China use glue department generally existing environmental pollution the problem of, very
It is in big degree because the formalin in adhesive is vaporizated into formaldehyde exhaust emissions to air in the reaction kettle of glue department
In caused by.As Wood-based Panel Production pollutant discharge of enterprise management upgrades, wood-based plate glue engineering environment protection emission requires to be gradually increased, urgently
The problem of the realizing control glue exhaust emissions that improve equipment need to be passed through.
Utility model content
To solve the problems, such as that it is not in place that the environmental protection measures such as wastewater treatment and waste emission that existing glue department generates are put into,
The utility model proposes a kind of glue tail gas recycling systems.
The glue tail gas recycling system of the utility model, it is characterised in that including reaction kettle, condenser, waste water tank,
Centrifugal blower, scrubbing tower, water circulating pump, heat exchanger and water-closing-barrel composition, in which:
Condenser is set at the top of reaction kettle, reaction kettle, condenser, centrifugal blower and scrubbing tower air inlet pass through tracheae
It is sequentially connected, the air inlet is set to tower body lower part；Several spray heads, the first water outlet of bottom setting is arranged in scrubbing tower internal upper part
Mouthful, the first water outlet, waste water tank and reaction kettle are sequentially connected by water pipe.
Due to the reaction kettle heating in glue department, formalin is vaporized into formaldehyde gas, by condenser one end from
Heart blower extracts formaldehyde gas out, condenses by condenser, and it is volatile that condenser is mainly used for condensing formaldehyde etc. in glue reaction
Object, about 75% formaldehyde gas flow back into reaction kettle.Residual formaldehyde gas enters scrubbing tower after condensation, and formaldehyde gas is from lower part
Into up walking, pure water is sprayed from top, and the contact area both expanded improves the absorption efficiency of formaldehyde, and after absorbing
Waste water formaldehyde can be recycled in waste water tank, content of formaldehyde is about 1.5-4% in waste water tank, can be added in reaction kettle in glue
Carry out using.Make formaldehyde without outlet, while also improving raw material availability.
The wash tower bottoms are additionally provided with the second water outlet, the second water outlet, water circulating pump, heat exchanger and scrubbing tower
Interior spray head is connected by water pipe.
Glue tail gas recycling system further includes water-closing-barrel, and spray head is provided in water-closing-barrel, and heat exchanger water outlet is same
When and water-closing-barrel spray head pass through water pipe connect；The spray head of setting water pipe and scrubbing tower is connected by water pipe in water-closing-barrel.
Water pump is arranged in one water outlet of waste water tank water outlet and scrubbing tower, the first water outlet.
After scrubbing tower spray, formaldehyde tail gas enters water-closing-barrel re-absorption, absorption efficiency is improved, by a set of tail gas absorption
The processing of device, most formaldehyde gas recycle after being absorbed, residual exhaust by heat exchanger cool down after in water-closing-barrel
It inside absorbs again, finally outdoor is finally discharged in only a small amount of formaldehyde gas.
The glue tail gas recycling system of the utility model, simple and practical in structure, not only formaldehyde emissions meet environmental protection and want
It asks, while also improving raw material availability.
