Description
Technical field
The present invention relates to glass production exhaust gas processing device field, specifically a kind of dual alkali scrubbing FGD process dust pelletizing system.
Background technology
Increase along with human production activity and social activities, particularly since the industrial revolution, due to the discharge of burning, industrial waste gas and the vehicle exhaust of fuel in a large number, atmosphere quality is worsened increasingly, China is also since reform and opening-up, economy obtains fast development, but air quality is also in continuous deterioration.Nowadays, the environmental protection consciousness of China is constantly strengthened, no matter be national large enterprise, or the small-sized unit of individual enterprise, all protection of the environment is placed above the other things and put, common for making a clean home effort.
Glass melting is a high-temperature chemical reaction process, source exhaust gas is in fuel combustion and raw material reaction, the main waste gas producing has: carbon dioxide, sulfur dioxide, carbon monoxide, nitric oxide and exhaust gas dust etc., coloured glass is produced and is also had volatile colouring agent, outside removing carbon dioxide, other is harmful components.
Therefore after will processing in time the tail gas in Improving Glass Manufacturing Processes, can discharge, existing exhaust gas processing device is mostly bulky, and treatment effect is not good, easily causes the pollution of environment.
Therefore, for overcoming the deficiency of above-mentioned technology, design a kind of dual alkali scrubbing FGD process dust pelletizing system that can have extraordinary vent gas treatment effect, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of dual alkali scrubbing FGD process dust pelletizing system, its device is simple; easy to operate; can extraordinary the tail gas producing in Improving Glass Manufacturing Processes be processed, protected environment, have extraordinary practical value.
