detailed description

The principles and features of the present utility model are described below in conjunction with examples, and the examples are only used to explain the utility model, and are not used to limit the scope of the utility model.

A granulation waste gas treatment device, characterized in that it includes a cooling dust collector 101, an electrostatic dehumidifier 201, an activated carbon adsorber 301, and a fan 401 connected in sequence by pipelines, and the cooling dust collector 101 is provided with a water tank, a circulating water pump and a water tank. Cord wind or water distribution system, the electrostatic dehumidifier 201 is provided with a filter screen, a discharge plate and a control box, and the activated carbon adsorber 301 is provided with activated carbon or filter cotton;

The water curtain is a multi-stage reentrant collision water curtain;

The filter screen is an aluminum alloy pressed three-dimensional filter screen;

The discharge plate is a stainless steel plate;

The fan 401 is a variable frequency fan.

The working process of the above-mentioned granulation waste gas treatment device is as follows:

The granulation waste gas produced in the regenerative granulator enters the cooling and dust collector 101 through the pipeline for cooling and dust removal. After cooling and dust removal under the action of circulating water, it enters the electrostatic dehumidifier 201 through the pipeline, and is filtered by the filter, and the discharge plate absorbs fine particles. After entering the activated carbon adsorber 301, the toxic and harmful gases are absorbed by the activated carbon and then enter the fan 401 to be discharged through the chimney.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
