Organic waste liquid pulsating combustion pyrolysis device and method

Abstract

The invention relates to an organic waste liquid pulse combustion pyrolysis device. A fluidized bed is included and provided with a filler inlet and a discharging port. The organic waste liquid pulsecombustion pyrolysis device is characterized in that a waste liquid sprayer, a gas furnace and pulse combustors are further included; the waste liquid sprayer is arranged at the top end of the fluidized bed, a porous air distribution plate is arranged at the bottom end of the bed layer of the fluidized bed, the end portion of the gas furnace is connected with a hot air supply pump, the hot air supply pump communicates with the porous air distribution plate through an air supply pipe, and the multiple pulse combustors are horizontally arranged in the fluidized bed. The invention further relatesto an organic waste liquid pulse combustion pyrolysis method. The method comprises the first step of filler fluidization, the second step of pulse combustion heating, the third step of organic wasteliquid pyrolysis and the fourth step of discharging collecting. According to the waste liquid pyrolysis device, the pulse combustors are used for heat supply, energy consumption is low, the heat efficiency is high, and pollutant emission is low. Compared with a waste liquid incineration treatment method, by means of the pyrolysis method, generated acid gas, dioxin and secondary pollutants are obviously reduced.

Description

technical field [0001] The invention belongs to the field of waste liquid pyrolysis treatment, and relates to a waste liquid pyrolysis device, in particular to a pulse combustion pyrolysis device and a method for organic waste liquid. Background technique [0002] Wastewater refers to the general term for water discharged from residents' activities, industrial production, and experimental processes and runoff rainwater. It includes domestic sewage, industrial waste water, experimental waste water and other useless water such as the inflow of primary rainwater into drainage pipes and canals. . [0003] As one of the three major public hazards in nature, organic wastewater will pollute surface water if it flows directly into channels, rivers and lakes. If the toxicity is high, it will lead to the death or even extinction of aquatic animals and plants. Such organic wastewater may also penetrate into groundwater and pollute the groundwater. If the surrounding residents use t...

Some wastewater containing organic waste liquid also has an unpleasant stench and pollutes the air

Toxic and harmful substances in organic wastewater will remain in the body through the ingestion and absorption of plants, and then reach the human body through the food chain, causing harm to the human body

[0004] At present, the treatment method of organic waste liquid in my country is incineration, but the incineration process of organic waste liquid has obvious disadvantages: high energy consumption, high requirements for equipment (high temperature resistance, corrosion resistance), easy to produce secondary pollutants (acid gas , dioxin, etc.), the treatment of organic waste liquid is far from reaching the level compatible with its discharge
