Formaldehyde in tail gas, if being provided with multistage absorption tower, the absorption tower 2 in the present embodiment refers generally to the last one absorption tower,
The tail gas of discharge needs to carry out burning processing.Set combustion furnace 3 to the tail gas of discharge for carrying out burning processing, Formaldehyde Production
When the tail gas that is discharged include a large amount of imflammable gas and pernicious gas, environmental pollution is enough lowered by burning, is reduced flammable
Security risk existing for property gas.Liquid seal trough 1 is set between absorption tower 2 and combustion furnace 3, and gas passes through liquid in liquid seal trough 1
Absorbing and filtering after be just discharged.Explosion stack 14 of the liquid seal trough 1 including tank body 11 and positioned at 11 top of tank body in the present embodiment,
It is connected with control valve 15 on the explosion stack 14, the break-make for controlling 14 pipeline of explosion stack.The connection of explosion stack 14 and tank body 11
Position is provided with pressure sensor, i.e., after control valve 15 is closed, one section of the lower section of explosion stack 14 is connected to 11 inside of tank body, at this
Pressure sensor, the pressure for detecting tank interior is arranged in connected component.Can also liquid level gauge 17 be set in 11 side wall of tank body, use
Liquid level in observation tank body.It can be equipped with outflow valve 18 simultaneously, for adjusting liquid level.In course of normal operation, with
The connected inlet pipeline 13 in absorption tower 2 extend into 11 bottom of tank body, and outlet is liquid-immersed, Liquid level in a certain range,
The gas being then discharged is located at the top in tank body, and is delivered to 3 bottom of combustion furnace by outlet conduit 16 and burns.If combustion
Burning stove 3, there are failures, and the gas lighted to be caused to enter tank body 11 from outlet conduit 16 there are certain failure or other parts
It is interior, it will so that pressure in tank body 11 is increased sharply, and this dangerous due to being in closed state, it is difficult to be found, if not
It can effectively solve the problem that, fire spreading may be made to other parts, or even tank body 11 can be made to explode.And the present embodiment due to
It is provided with pressure sensor, when pressure sensor detects that pressure is more than the limiting value of setting in tank body 11, signal can be passed
It send to processor, processor promotes control valve 15 to open, then can be exhausted by explosion stack 14, although gas may be
Explosion stack nozzle burns away, but will not affect greatly in a short time.It can be carried out by effective mode in this period
Fire extinguishing is handled, and can be returned to normal production in the short time, be avoided the deterioration of accident, and can effectively reduce loss.The dress
It sets and is connect with automatic control system, automatic control system includes infrared spectrometer and display screen and picture recognition module, infrared
Fluid flowing in whole device is included on display screen by spectrometer, and picture recognition module identifies the figure on the display screen
Picture, and operated accordingly according to all parts of the flow regime control system of fluid.
Embodiment 2
A kind of flame retardant type formaldehyde exhaust gas processing device of the present embodiment, basic structure is same as Example 1, difference
Be in：11 top of tank body is additionally provided with buffer 12, and the inlet pipeline 13 on the buffer 12 is connected with absorption tower 2, passes through
Buffer 12 reduces tail gas flow velocity.In conjunction with Fig. 3, buffer 12 is mainly made of annular chamber 121 and buffering connecting leg 124, annular chamber
121 upper ends are connected with inlet pipeline 13, and 121 lower end of annular chamber connection buffering connecting leg 124, the buffering connecting leg 124 is passed through tank body 11
Bottom.The diameter that 121 diameter of annular chamber is more than inlet pipeline 13, buffers connecting leg 124, diameter mentioned here refers to internal diameter,
In the case that wall thickness is equal, outer diameter can form cylindrical protrusions.Since 121 internal diameter of annular chamber is larger, when the gas of inlet pipeline 13
After flowing into annular chamber 121, flow velocity reduces, since the internal diameter of buffering connecting leg 124 is less than 121 internal diameter of annular chamber, air-flow
Certain vortex can be formed, the air-flow velocity into buffering connecting leg 124 reduces.Due to flow velocity reduce, air-flow from buffering connecting leg 124
After bottom enters in liquid, it is formed by the specific surface area increase that bubble is relatively small, is contacted with liquid, helps to inhale
Pernicious gas in getter body.In addition, if not buffering setting, air-flow directly impacts 11 bottom of tank body, has one to tank body 11
Fixed damage, and pass through after buffering, this damage can be reduced, the service life of tank body is extended.
Embodiment 3
A kind of flame retardant type formaldehyde exhaust gas processing device of the present embodiment, basic structure is same as Example 2, difference
Be in：Tank body 11 is connected with water circulation system in the present embodiment, is cycle aqueous in tank body 11, then can be made by recirculated water
It is in unsaturated state, has stronger adsorption capacity, improves assimilation effect.Further, in order to improve buffering effect,
It is provided with sieve 123 in annular chamber 121, is located at the inlet of buffering connecting leg 124.Sieve 123 has air-flow certain blocking
Effect.In addition, the gas of discharge is gas liquid mixture, air-flow can be filtered by set sieve.
Embodiment 4
A kind of flame retardant type formaldehyde exhaust gas processing device of the present embodiment, basic structure is same as Example 3, and difference exists
In：It is provided with sieve 123 in annular chamber 121, is located at 121 middle part of annular chamber, as shown in figure 3, being provided with above sieve 123
Filler is buffered, which is steel wool 122.It is worth noting that steel wool 122 is finer and closely woven relative to sieve, have more
Good choked flow effect, can be improved buffering effect.But if steel wool is arranged in the inlet of buffering connecting leg 124, the pressure of air-flow
Power can make its have it is certain pile up, be easy to block buffering 124 entrance of connecting leg, then air-flow is difficult to enter in buffering connecting leg 124.And this
Embodiment is arranged sieve 123 at the middle part of annular chamber 121, and downside still has larger circulation area, into row buffering
Meanwhile Airflow obstruction will not be caused, structure setting is reasonable.
Embodiment 5
In conjunction with Fig. 4, a kind of flame retardant type formaldehyde exhaust gas processing device of the present embodiment, basic structure is same as Example 4,
The difference is that：11 side wall of tank body is provided with U-shaped control position pipe.U-shaped control position pipe is connected to tank interior, can be according to need
It is arranged in specified altitude assignment, when liquid level amount increases, liquid can be flowed outwardly automatically by the U-shaped control position pipe, can be very
Good control liquid level, does not need manual adjustment.
Automatic control system includes infrared spectrometer and display screen and picture recognition module, and infrared spectrometer will be filled entirely
Fluid flowing in setting is shown on display screen, and picture recognition module identifies the image on display screen, and according to the flowing of fluid
The information such as the flow regime of gas and flow in each container of condition adjudgement and pipeline, each portion based on this management information system
Part is operated accordingly.By way of automatically controlling, the processing procedure of tail gas can be efficiently and accurately handled, and can be in detail
The parameter storage of each process is recorded on ground, is used for analysis；Due to eliminating the operation of people, whole process is using automation
Processing mode ensure that the accuracy of parameters control.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
