Steam sprinkling type smoke purifier of furnace

Abstract

The invention relates to smoke purification of furnaces and provides a steam sprinkling type smoke purifier of a furnace. The steam sprinkling type smoke purifier of the furnace is provided with a main combustion chamber and an auxiliary combustion chamber side by side. A dust collection chamber is arranged on the upper portion of the main combustion chamber. A cylindrical cyclone centrifugal dustremover is perpendicularly arranged on the upper portion of the dust collection chamber. A smoke discharge pipe is vertically arranged at the center of the inner portion of the cyclone centrifugal dust remover. An auxiliary combustion chamber smoke pipe is arranged on the upper portion of the auxiliary combustion chamber. The auxiliary combustion chamber smoke pipe is connected with the side faceof the cyclone centrifugal dust remover in a sealed manner from the side face in the tangential direction. A steam generator is arranged on the circumference on the outer wall of the lower portion ofthe auxiliary combustion chamber smoke pipe and provided with a water replenishing tank through a water replenishing pipe. Alkaline liquid is fed into the steam generator and the water replenishing tank. A mist spray pipe is arranged on the steam generator. The mist spray pipe is provided with a steam spray nozzle. The steam spray nozzle extends into the cyclone centrifugal dust remover from theside face in the tangential direction. Smoke dust and steam form swirling flow in the cyclone centrifugal dust remover.

Description

technical field [0001] The invention is related to the technical fields of environmental protection treatment of stoves and incineration treatment of urban and rural domestic waste. Background technique [0002] At present, all countries in the world attach great importance to the treatment of urban and rural garbage. The annual output of "urban garbage" in China alone is nearly 150 million tons. About 2 / 3 of China's cities are trapped in the predicament of garbage siege. Most of these urban garbage are piled in the open. It not only affects the urban landscape, but also pollutes the atmosphere, water and soil that are vital to our lives, and poses a threat to the health of urban residents. Garbage has become a thorny issue in urban development. At present, landfill is the main method of garbage disposal in my country, but landfill will cause pollution to water resources, soil, and atmospheric environment, and also cause a lot of waste of land resources. In recent years, so...

Problems solved by technology

At present, landfill is the main way to deal with waste in my country, but landfill will cause pollution to water resources, soil, and atmospheric environment, and also cause a lot of waste of land resources.

In recent years, some waste incineration equipment has appeared on the market, but there are generally factors such as large investment in equipment, high operating costs, and high energy consumption costs of the equipment itself, which are not conducive to popularization and application.
