A kind of gas extraction system of printing equipment
Technical field
The utility model relates to toxic emission field, is specifically related to a kind of gas extraction system of printing equipment.
Background technology
Need to dilute ink with diluent for the ease of utilization ink such as printing machines because needs use ink, because diluent easily volatilizees in air in dilution, and solvent use amount is larger, if solvent is evaporate in air, atmosphere pollution can be caused, and the use amount of solvent every day is comparatively large, cost is higher, huge cost will be caused like this to drop into lack to cause serious atmosphere pollution.
To the waste gas produced in printing industry production process carry out process be enterprise development arrive certain scale time corollary, what produce in printing industry is mainly organic exhaust gas, it is mainly because the use of printing-ink causes, cause personal injury and atmosphere pollution on the one hand, also result in the huge waste of organic solvent on the other hand, these waste gas smells are strong, inflammable and explosive, danger is very large, the off-gas cleaning equipment of prior art is difficult to reach absolute control and pollution administration to described printing technology, and also increase the unreliability of factory safety, high-concentration waste gas only carries out primary first-order equation with scavenging solution, process not exclusively, serious to atmosphere pollution, be difficult to the standard reaching the discharge of national secondary.Need again to process waste gas, cost will improve greatly.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of gas extraction system of printing equipment, to realize discharge and the filtration of printing process volatility ink, ensures workshop condition and workers ' health.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of gas extraction system of printing equipment, comprise printing table, more than one air-suction cover is provided with above described printing table, described air-suction cover connects the exhaust main of horizontally set by tube connector, described exhaust main end is divided into exhaust piping and upper and lower two pipelines of dust discharge pipeline, described dust discharge pipeline is provided with dust catcher, the dust-exhausting port of described dust catcher connects sealed cistern by a flexible pipe, described exhaust piping is provided with charcoal absorption filter, described charcoal absorption filter connects chimney, is provided with blower fan between described charcoal absorption filter and chimney.
As preferably, described blower fan is centrifugal blower.
As preferably, described tube connector is provided with control valve.
Concrete, described exhaust piping is provided with a screen pack.
The utility model beneficial effect is: first, and the utility model structure is simple, and the waste gas be conducive to printing machine produces purifies, and not only protects atmospheric environment, also ensure that the health of operating personnel; Secondly; The setting of screen pack on exhaust piping, stops larger trash in pipeline to enter charcoal absorption filter, increases the absorption burden of this filter; Finally, dust catcher can be inhaled absorbing and filtering is online smoothly trash, and then flow in sealed cistern by dust-exhausting port through flexible pipe, the solution that sealed cistern absorbs soluble substance utilizes further, improves the utilization rate of resource.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
In figure: 1. printing table, 2. air-suction cover, 3. tube connector, 4. exhaust main, 5. dust discharge pipeline, 6. exhaust piping, 7. dust catcher, 8. dust-exhausting port, 9. sealed cistern, 10. charcoal absorption filter, 11. chimneys, 12. blower fans, 13. control valves, 14. screen packs.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings 1, the technical solution of the utility model is described in further detail.
Embodiment is shown in the attached gas extraction system that Figure 1 shows that a kind of printing equipment described in the utility model, comprise printing table 1, more than one air-suction cover 2 is provided with above described printing table 1, described air-suction cover 2 connects the exhaust main 4 of horizontally set by tube connector 3, described exhaust main 4 end is divided into dust discharge pipeline 5 and exhaust piping about 6 two pipe, described dust discharge pipeline 5 is provided with dust catcher 7, the dust-exhausting port 8 of described dust catcher 7 connects sealed cistern 9 by a flexible pipe, described exhaust piping 6 is provided with charcoal absorption filter 10, described charcoal absorption filter 10 connects chimney 11, blower fan 12 is provided with between described charcoal absorption filter 10 and chimney 11.Described blower fan 12 is centrifugal blower.Described tube connector 3 is provided with control valve 13.Described exhaust piping 6 is provided with a screen pack 14.
The gas extraction system of a kind of printing equipment that embodiment provides, by air-suction cover 2, siphon away the waste gas and dust that produce in printing process, exhaust piping 6 is provided with screen pack 14, dust siphons away by the dust catcher 7 be convenient on dust discharge pipeline 5, then flowed in sealed cistern 9 through flexible pipe by dust-exhausting port 8, the solution that sealed cistern 9 absorbs soluble substance utilizes further; Waste gas is through charcoal absorption filter 10, and the toxic gas produced in absorption printing process, purified gas is discharged by chimney 11, reduces waste gas to the pollution of environment.Further, air-suction cover 2 with the tube connector 3 of exhaust main 4 are provided with control valve 13, according to the real work situation of printing machine, wind-force size can be regulated.
The present embodiment is the embodiment of the utility model example; technical conceive of the present utility model and feature; its object is to person skilled in the art scholar understand content of the present utility model and implemented; can not limit protection domain of the present utility model with this, all equivalences done according to the utility model Spirit Essence change or modification all should be included in protection domain of the present utility model.
