Batch-type painting system using heat storing combustion method

Abstract

The present invention relates to a batch-type painting system which enables painting and drying, which have previously been in separate systems, to be implemented together in one system, and which uses a heat storing combustion method that, through a combustion method, burns and eliminates harmful substances generated during painting instead of using activated carbon or a catalyst to filter the substances and remove them through a filter device, in order to minimize the concentration of harmful substances in exhaust gas. The system is configured to comprise: a ventilation chamber connected toan intake port through which fresh air is suctioned by means of a fresh air supply line on which a valve A is installed, and provided with a filter and a ventilation fan therein; a painting booth connected to the ventilation fan of the ventilation chamber via a ventilation line, connected to the ventilation chamber on the other side of the fresh air supply line via an exhaust line on which a valveB is installed; heat storing-type combustion equipment having a distribution chamber connected to an exhaust filter and a discharge gas line of the painting booth, having a ventilation fan B installed on the discharge gas line, having the distribution chamber on the other side of the discharge gas line connected to the ventilation chamber via a processed gas circulation line, and having a valve Cinstalled on the processed gas circulation line; and a processed gas discharge line branched from the processed gas circulation line at the front side of the valve C of the heat storing-type combustion equipment, and having a valve D installed therein.

Description

technical field [0001] The present invention relates to an intermittent paint spraying system utilizing a regenerative combustion method. More specifically, it relates to the fact that the paint spraying and drying performed by separate systems in the past can be performed together in one system, and are not removed by filtration and filtration devices using activated carbon or catalysts. It is an intermittent painting system that utilizes a thermal storage combustion method that minimizes the concentration of harmful substances in the exhaust gas by burning harmful substances that are generated during painting. Background technique [0002] Generally, a paint booth is formed by a system that sprays paint on a product to be painted by spraying, and supplies hot air of an appropriate temperature to the interior of the paint booth to dry the painted product. Explain how this spray booth works as follows. If the product is put into the spray booth, the spraying operation is ca...

[0005] On the other hand, the filtration device or filter device used in the conventional painting booth mainly uses activated carbon or a catalyst to remove pollutants contained in the air and gas. At this time, the dust and pollutants generated when painting are Adhering to the filter and accumulating, as a result, the filter will be clogged, and the filtering function will be lost, and the high concentration of harmful substances in the atmosphere will be discharged, resulting in serious environmental pollution. It is necessary to alternately filter and filter periodically device and high-priced catalyst device, the economy will be reduced
