Abstract
The invention belongs to the technical field of chemical engineering equipment, and in particular, relates to a system for treating waste liquid containing formaldehyde. The system comprises a waste liquid tank, a waste liquid pump, an electromagnetic valve, an atomizer, a wind box, a combustion fan and a waste liquid incinerator, wherein the waste liquid tank is connected with the waste liquid pump; the waste liquid pump is connected with the atomizer through the electromagnetic valve; the atomizer is connected with the wind box; the wind box is respectively connected with the combustion fan and the waste liquid incinerator; the waste liquid incinerator is connected with a gas collection tank through a chimney; a tail gas box is connected with an absorbing device through an exhaust pipe; and a porous absorbing material is mounted in the absorbing device. The system can incinerate the formaldehyde-contained waste liquid with high temperature to totally oxidize and decompose to carbon dioxide and water; and a trace of remainder harmful substances are discharged after being absorbed by the absorbing device, so that the environmental pollution is effectively prevented.
Description
Technical field
The invention belongs to technical field of chemical, be specifically related to a kind of liquid waste treatment system containing formaldehyde.
Background technology
At present, the processing method of a large amount of formaldehyde-containing wastewater, main the processing method-----biochemical process (anaerobism, oxygen consumption method) adopting routine, but because this method floor space is large, equipment is many, long operational time, costly, process is not thorough, still containing many harmful substances in emission, to environment.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above and provide a kind of liquid waste treatment system containing formaldehyde, waste liquid complete oxidation can be resolved into carbon dioxide and water by it, avoids environmental pollution.
For achieving the above object, the present invention is by the following technical solutions:

The inlet of described waste liquid tank connects waste liquid delivery pump by pipeline.
Described porous adsorbing material is slag, molecular sieve or resin, active carbon.
Present system can by waste liquid by high temperature incineration, and complete oxidation resolves into carbon dioxide and water, and the harmful substance of remaining trace carries out discharging after adsorption treatment through adsorbent equipment again, effectively prevent environmental pollution.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the liquid waste treatment system containing formaldehyde that the embodiment of the present invention provides.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Refer to Fig. 1, a kind of liquid waste treatment system containing formaldehyde, comprises waste liquid tank 1, waste drains pump 3, magnetic valve 4, atomizer 5, bellows 6, combustion fan 7, liquid waste incinerator 8; Waste drains pump 3 described in described waste liquid tank 1, described waste drains pump 3 connects described atomizer 5 by described magnetic valve 4, described atomizer 5 is connected with described bellows 6, described bellows 6 are connected with described liquid waste incinerator 8 with described combustion fan 7 respectively, described liquid waste incinerator 8 connects plenum chamber 11 by chimney, described plenum chamber 11 connects adsorbent equipment 12 by blast pipe, and described adsorbent equipment 12 is built with porous adsorbing material.
Described liquid waste incinerator 8 inside is provided with combustion chamber 10, and described combustion chamber 10 is connected with described bellows 6.
Further, described atomizer 5 is connected with described bellows 6 by air-pressure tube 9.
Further, the inlet of described waste liquid tank 1 connects waste liquid delivery pump 2 by pipeline.
Described porous adsorbing material is slag, molecular sieve or resin, active carbon.
During work, first waste liquid is delivered to waste liquid tank 1 by waste liquid delivery pump 2, starting waste drains pump 3 makes waste drains pump 3 outlet pressure keep under pressure, opens solenoid valve 4 and atomizer 5, regulate the pressure that the pressure of air-pressure tube 9 is being applicable to, prevent the high temperature in combustion chamber 1 from burning out atomizer 5, waste liquid enters atomizer 5 and is atomized, waste liquid keeps spray pattern to enter bellows 6, open combustion fan 7, supplement the oxygen that incineration of liquor consumes, atomization waste liquid enters combustion chamber 10 with the oxygen supplemented by bellows 7, in the combustion chamber 10 of temperatures as high 500 DEG C, waste liquid complete oxidation resolves into carbon dioxide and water, the waste gas produced enters in plenum chamber 11 through chimney, and then enter in described adsorbent equipment through blast pipe, further adsorbed by the porous adsorbing material in described adsorbent equipment 12, complete for harmful substance adsorption treatment can be fallen, find after testing, in the gas of discharging after absorption, formaldehydeless composition exists.
Present system can by waste liquid by high temperature incineration, and complete oxidation resolves into carbon dioxide and water, and the harmful substance of remaining trace carries out discharging after adsorption treatment through adsorbent equipment again, effectively prevent environmental pollution.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
