Invention content
In order to solve the above technical problems, the present invention provides a kind of casting exhaust treatment system, including it is sequentially connected into Tracheae, spray pollutant-removing system, exhaust pipe, spray pollutant-removing system includes the spray chamber with the wind set gradually, filtration treatment room, contrary wind Spray chamber, spray chamber, filtration treatment room, the connection of contrary wind spray chamber bottom, filtration treatment room pass through logical with contrary wind spray chamber with the wind Air hose is connected to, and air inlet pipe is connected to spray chamber with the wind, and exhaust duct is connected to contrary wind spray chamber.
Technique effect:It can make that cleaning solution is more abundant with exhaust gas contact by the way of spray, to remove exhaust gas In impurity, when exhaust gas for the first time into can make using spray with the wind by the way of cleaning solution and give up in spray pollutant-removing system in this way Gas comes into full contact with, before going out spray system in such a way that contrary wind sprays, so that time of the exhaust gas in spray system It is longer, so that exhaust gas is fully cleaned.
The technical solution that the present invention further limits is:
Further, air inlet pipe is connected with exhaust fan backwards to spray chamber one end with the wind.
A kind of preceding casting exhaust treatment system, with the wind spray chamber be all provided with side wall along its roof and once spray Pipe, No. one time spray tube is equipped with several spray heads.
A kind of preceding casting exhaust treatment system, filtering spray chamber roof are equipped with secondary spraying pipe, secondary spraying pipe Several spray heads are equipped with, filter layer is equipped with below spray head.
A kind of preceding casting exhaust treatment system, ventilation duct is interior to be equipped with for the indoor gas of filtration treatment to be drawn to The suction ventilator of contrary wind spray chamber.
A kind of preceding casting exhaust treatment system, ventilation duct both ends are respectively communicated to filtration treatment room and spray against the wind The top of room, contrary wind process chamber top are equipped with adsorption layer with ventilation duct junction.
A kind of preceding casting exhaust treatment system, the interior spray tube three times being equipped in inverted L-shaped setting of contrary wind spray chamber, The lattice block for being close to setting with adsorption layer is equipped with above spray tube three times.
A kind of preceding casting exhaust treatment system, exhaust treatment system further includes water circulating pump, water circulating pump one end It is connected to contrary wind spray chamber bottom, the other end is connected to secondary spraying pipe and three times spray tube.
The beneficial effects of the invention are as follows:
(1)Using spray with the wind and against the wind, spray mode makes so that cleaning solution is more abundant with exhaust gas contact in the present invention Obtain exhaust gas;
(2)The cleaning solution in spray system three times is recycled in the present invention, is greatly saved water resource, environmentally friendly nothing Pollution so that exhaust gas becomes pure air discharge again.

Specific implementation mode
A kind of casting exhaust treatment system provided in this embodiment, structure is as shown in Figure 1, include sequentially connected air inlet pipe 1, pollutant-removing system and exhaust pipe are sprayed, exhaust gas is entered by air inlet pipe 1 in spray pollutant-removing system, is handled by spraying pollutant-removing system It is discharged again by exhaust pipe to clean gas.
Air inlet pipe 1 is connected with exhaust fan 11 backwards to 2 one end of spray chamber with the wind, will be generated in casting process by exhaust fan 11 Exhaust gas is evacuated in spray chamber 2 with the wind, and is connected to and is sprayed on roof with the wind.Intake can be increased in this way, improve working efficiency.
It includes the spray chamber with the wind 2 set gradually, filtration treatment room, contrary wind spray chamber 4 to spray pollutant-removing system, is sprayed with the wind Room 2 is equipped with a spray tube 21 along its roof and side wall, and a spray tube 21 is equipped with several nozzles, in a spray tube 21 Equipped with NaOH alkalinity neutralizers, for neutralizing the acidic materials in exhaust gas, to avoid acidic materials from being discharged.And due to using The mode sprayed with the wind, can increase the contact area with exhaust gas in this way so that cleaning is more felt.An and spray tube Neutralizer in 21 can not only neutralize the acidic materials in exhaust gas, can also tentatively remove the impurity in exhaust gas.
2 bottom of spray chamber is connected to filtering spray chamber 3 with the wind, and is formed clearly with filtering spray chamber 3 in spray chamber 2 with the wind Washing lotion layer, exhaust gas are entered to by layer of cleaning solution in filtering spray chamber 3, and filtering 3 roof of spray chamber is equipped with secondary spraying pipe 31, secondary Spray tube 31 is equipped with several spray heads, and filter layer 32 is equipped with below spray head.The little particle that filter layer 32 removes in exhaust gas is miscellaneous Matter further purifies exhaust gas, due to the mode that bright cloud sprays against the wind, can increase exhaust gas in this way in spray pollutant-removing system In residence time, so that it is more abundant to the processing of exhaust gas.
It is equipped with ventilation duct 5 between the top and the top of contrary wind process chamber of filtration treatment room, suction ventilator is equipped in ventilation duct 5 51, the indoor gas of filtration treatment is drawn in contrary wind spray chamber 4, is equipped with and inhales with 5 junction of ventilation duct at the top of contrary wind process chamber Attached layer 42.Peculiar smell in 42 draw exhaust of adsorption layer ensures to keep clean when gas discharge.
Spray tube 41 three times in inverted L-shaped setting are equipped in contrary wind spray chamber 4, spray tube 41 is equipped with several sprays three times Head, 41 top of spray tube is equipped with the lattice block 43 for being close to setting with adsorption layer 42 three times.In this way so that exhaust gas is first passed through and sprayed three times Spray head in shower pipe 41 is then exhausted from after carrying out contrary wind spray, and gas is prevented to be expelled directly out.
Water circulating pump 6 is additionally provided with outside spray pollutant-removing system, water circulating pump 6 extracts the cleaning solution cycle in contrary wind spray chamber 4 It utilizes, water resource waste can be reduced in this way.
It is equipped with demisting layer 71 in exhaust duct 7, reduces steam discharge in this way.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape At technical solution, fall within the scope of protection required by the present invention.
