Description
Technical field
The utility model relates to the treatment facility of formaldehyde in a kind of super E0 grade urea-formaldehyde resin adhesive production, belongs to Lauxite synthesis technical field.
Background technology
Urea-formaldehyde resin adhesive is widely used in industrial every field, is the compound being generated with certain molar ratio reaction by formaldehyde and urea.One of raw material formaldehyde steam is comparatively serious to the pollution of environment, in synthetic because production equipment is complicated, the problem ubiquity that formaldehyde leaks, main manifestations is: the formaldehyde gas during discharging of (1) raw material formaldehyde tank car in storage tank is easily extruded storage tank in a large number, causes air pollution; (2) formaldehyde passes into after preparation system, and before not entering reactor, part formaldehyde directly enters in air by storing high-order exhaust outlet; (3), when raw material formaldehyde drops into reactor, excessive formaldehyde gas volatilization enters air; (4) port lid of often opening reactor due to needs in production process operates, and formaldehyde gas more easily evaporate in a large number in air in the situation that of heating; (5) in reactor, untapped formaldehyde gas needs to vacuumize in follow-up flow process, and formaldehyde gas easily enters air from exhaust outlet.
From the problems referred to above, can find out, in the preparation process of Lauxite, it is very important step that the whole process of formaldehyde is processed.In the report of existing document, in the preparation system of Lauxite, the formaldehyde treated method of employing is concentrated and is: the evacuation port of (1) Formaldehyde Tank is tried one's best and high stretched in the air, utilizes eminence air-flow dilution formaldehyde gas and takes away.Shortcoming is still can contaminated air; (2) reactor reinstalls stream condensing plant, and the formaldehyde gas that makes to be evaporated is condensed into liquid and passes back into reactor again.The incoagulable gas evacuation port that condenser connects still has part formaldehyde gas and leaks.
So, can solve all problems simultaneously, be only and solve the omnidistance key of processing of formaldehyde.And in order to reach the index of E0 grade urea-formaldehyde resin adhesive, the mol ratio of raw material formaldehyde and urea needs again point-device control, this requires very high to the circuit design of preparation system again, if design too much pipeline branch road in order to reach all formaldehyde treated problems of solution, too much valve etc. is installed, will need to write the more complicated control program that feeds intake, the possibility that formaldehyde is utilized is completely just less, be difficult to reach the index of Lauxite E0 level, and can process the problem of whole formaldehyde, can keep the equalization point of Lauxite quality again, to need at present the key of the problem of solution.
Summary of the invention
The utility model provides the treatment facility of formaldehyde in a kind of super E0 grade urea-formaldehyde resin adhesive production, adopts a plurality of loop designs, and each loop directly passes into absorption plant by residual formaldehyde, improves formaldehyde utilization rate, and environment is not produced to pollution, and control method is simple.
The utility model is to realize by following technical scheme:
A treatment facility for formaldehyde in super E0 grade urea-formaldehyde resin adhesive production, comprising:
Formaldehyde Tank connects head tank, and outlet one end of described head tank connects Formaldehyde Tank and forms Formaldehyde Tank head tank loop, and the other end connects formaldehyde absorption tank;
Described head tank bottom coupled reaction still, reactor top has condensing unit, and outlet one end of condensing unit connects head tank and forms head tank reactor loop, and the other end connects formaldehyde absorption tank;
Described reactor bottom connects water knockout drum and surge tank successively, and described surge tank connects water-ring vacuum pump, and water-ring vacuum pump connects a circulation water pot, and circulation water pot connects spray chamber, and spray chamber connects formaldehyde absorption tank.
Described condensing unit is continuously two condensers of series connection.
The pipeline that described formaldehyde absorption tank connects all stretches into below the liquid level that formaldehyde absorption tank inside takes up.
The described mouth of pipe place that stretches into the pipeline of formaldehyde absorption tank has screen pack.
The beneficial effects of the utility model are:
1. the utility model is by three loop designs in " Formaldehyde Tank head tank loop ", " head tank reactor loop " and " circulation water pot " loop, guaranteed that raw material formaldehyde is directly recovered in whole preparation system, formaldehyde absorption tank is finally pointed in each loop, reaches the object that formaldehyde reclaims completely.
2. the utilization rate of formaldehyde is enhanced, and by the setting of circuit design and control system, the circulation of formaldehyde is constantly circulation, and is just constantly utilized in circulation, can improve the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, be structural representation of the present utility model, be the treatment facility of formaldehyde during a kind of super E0 grade urea-formaldehyde resin adhesive is produced, specific works flow process is as follows:
1. the device for cleaning pipeline that transports the sealing tank car of formaldehyde is crossed and is opened valve V1 and V2 and formaldehyde is inputted to Formaldehyde Tank 1 carry out the preparation of Lauxite, open V3 and V4, formaldehyde in Formaldehyde Tank 1 will flow into head tank 2, formaldehyde in head tank can flow back to Formaldehyde Tank 1 by Formaldehyde Tank head tank loop, and the formaldehyde of failing to loop back Formaldehyde Tank injects tourie 10 by pipeline.
2. open V5; formaldehyde enters reactor 3 by head tank and carries out the synthetic and condensing reflux of Lauxite; reactor 3 has been connected in series condenser 4 and condenser 5; conventionally can adopt shell and tube condenser; when reactor heats, condenser 4 and condenser 5 reflux unreacted formaldehyde, open V6 and V7 simultaneously; excessive formaldehyde loops back head tank by head tank and reactor loop, and on-condensible gas directly enters tourie with a small amount of formaldehyde.
3. open V8-V11, having reacted rear product cleans through water knockout drum 6 and surge tank 7, remainder of exhaust gas is in company with entering water knockout drum and surge tank, can directly enter tourie 10 by V8, open V12, all right, by water-ring vacuum pump 8 constantly circulation in circulation water pot 9, after enter spray chamber 11, by atomizer, carry out spray-absorption, finally enter tourie and absorb.
