Oven drying system adopting organic waste gas combustion for heating

Abstract

The invention discloses an oven drying system adopting organic waste gas combustion for heating. The oven drying system adopting organic waste gas combustion for heating comprises a unit body, a unit body oven, a control center and a thermal incinerator. The unit body is a printer or/and a coating machine. Organic waste gas is generated when the unit body oven which is the printer or/and coating machine is used for drying. A recovery branch used for recovering the organic waste gas generated when the printer or/and coating machine operates is arranged in the unit body oven. A waste gas fan used for blowing the organic waste gas collected by the recovery branch into a combustion chamber in the thermal incinerator is arranged outside the unit body oven. A heat exchange tube is further arranged at an air inlet of the combustion chamber. High-temperature gas exhausted from the combustion chamber of the thermal incinerator is sequentially connected with a heat exchanger and a chimney used for exhausting the gas directly. A pipeline communicating with filtered fresh cold air in the outside is arranged in the heat exchanger. High-temperature hot air generated after high-temperature gas generated after combustion in the combustion chamber is cooled through indirect exchange with the fresh cold air enters the unit body oven to dry and heat products on the printer or/and the coating machine.

Description

【Technical field】 [0001] The invention relates to the printing or coating industry, in particular to an oven drying system utilizing organic waste gas combustion and heating. 【Background technique】 [0002] Oven drying is an important process link in printing and coating equipment. The purpose is to dry the paste slurry containing solvent or water and solidify it into shape. [0003] The heating methods of the existing oven mainly include: electric heating, heat medium heating, infrared heating and air heating. Electric heating is the most common simple and convenient method, which is widely used by small and medium-sized enterprises. Infrared heating uses the principle of electromagnetic radiation heat transfer to directly transfer heat to achieve the purpose of drying objects, thereby avoiding energy loss caused by heating the transfer medium. Heat medium heating is to heat the heat medium (heat transfer oil), and the high temperature heat transfer oil is transported by ...

Problems solved by technology

[0005] However, a boiler room occupies a large area, which cannot be configured by general factories and enterprises.

Moreover, it needs to burn a large amount of coal and other energy sources to generate heat. First, energy minerals are decreasing day by day, and second, coal combustion produces a large amount of dust particles, forming smog, causing serious environmental pollution, and having a serious impact on social security and personal health.
