Technical field

The present invention relates to coating waste gas process fields, and in particular to a kind of fountain environment-protecting cabinet.

Background technique

In the paint spray booth and curing equipment that paint industry generally uses, in order to reduce pollution of the exhaust gas to environment, reach National gas discharge standard, generallys use waste gas treatment equipment and handles exhaust gas, is discharged into again outside after reaching emission request Boundary.Environment-protecting cabinet can be divided into dry type and two kinds of wet type according to its structure difference.The environment-protecting cabinet of which kind of form is selected to be decided by user's The concrete condition of exhaust gas constituents and production.

Chinese publication CN 107694222A, publication date on 2 16th, 2018, entitled one kind of innovation and creation Exhaust-gas treatment environment-protecting cabinet, the invention disclose a kind of exhaust-gas treatment environment-protecting cabinet, comprising: a cabinet body, the bottom surface and top of the cabinet body Face is respectively equipped with air inlet and air outlet；At least one screen frame, the screen frame are fixed on the inner wall of the cabinet body；At least one Bag filter layer, each bag filter layer include multiple downward opening bag filters, the multiple bag filter In matrix arrangement, and it is fixed on the screen frame；One filter screen, the filter screen is fixed on the inner wall of cabinet body, and is located at The top of bag filter layer；One exhaust blower, the exhaust blower are located at the top of the filter screen, are installed by an installation frame In the inner cavity of cabinet body, and the air outlet of exhaust blower is connected to the gas outlet.Exhaust-gas treatment environment-protecting cabinet of the invention, structure letter It is single, high to the treatment effeciency of exhaust gas, and the requirement of country's discharge can be reached.

But its shortcoming environment-protecting cabinet is dry type environment-protecting cabinet and relies solely on two layers of pocket type strainer, is less than to particle and captures The problem of pollutant component of bag is difficult to handle, and a large amount of dust be easy to cause strainer to rapidly enter payoff period in air.

Summary of the invention

The present invention be directed to existing environment-protecting cabinets to rely on two layers of pocket type strainer, and the pollutant component for being less than capture bag to particle is difficult to The problem of processing, a large amount of dust be easy to cause strainer to rapidly enter payoff period in air, devising one kind can be in exhaust gas Dust carry out water mist filtering, and in exhaust gas pernicious gas carry out filter plates fountain environment-protecting cabinet.

A kind of fountain environment-protecting cabinet, comprising:

Cabinet body is arranged in earth's surface, and the downside back side is provided with air inlet, and top is provided with air outlet；

Exhaust fan, is arranged in the top of cabinet body, and the air outlet and the air outlet at the top of cabinet body of exhaust fan match, fix with cabinet body Connection；

Filter layer, setting below exhaust fan, are fixedly connected in cabinet body with cabinet body；
