Problems solved by technology

Although since the 1970s, developed countries in Europe and the United States have begun to devote themselves to the research and application of co-disposal technology for industrial kilns. In decades of production practice, this technology has played a huge role in the treatment and disposal of hazardous waste, but my country's hazardous waste co-disposal incineration technology is still in its infancy

Abstract

The invention discloses a common treatment hazardous waste combustion system of a grate-fired furnace and a method thereof. A water-cooled wall is distributed on a furnace wall of the upper portion of a hearth, the upper end of the hearth is provided with a steam pocket, the steam pocket is connected with the water-cooled wall, the upper portion of the hearth is connected with a burnout chamber, a grate is arranged below the hearth, the front end of the grate is provided with a front arch, the rear end of the grate is provided with a rear arch, the upper portion and the lower portion of the front arch are provided with a liquid feeding port and a solid feeding port respectively, a multi-stage primary air chamber is arranged below the grate, secondary air ports are arranged on two sides of the hearth and located on the upper portion of the liquid feeding port, and the tail of the grate is provided with a deslagging device. A liquid hazardous waste tank, a liquid hazardous waste feeding pump, a liquid hazardous waste spray gun and the liquid feeding port are connected in sequence, a solid hazardous waste feeder and a coal feeder are connected with the solid feeding port respectively through a sealed type mixed feeder, and the solid hazardous waste feeder is connected with a solid hazardous waste bin. The existing grate-fired furnace is effectively utilized to combust hazardous waste, and the storage cost and the environmental risk which are caused by the fact that the hazardous waste cannot be treated timely are reduced.

Description

technical field [0001] The invention relates to a layer combustion furnace incineration disposal technology for waste, in particular to a layer combustion furnace co-processing hazardous waste incineration system and a method thereof. Background technique [0002] According to the statistics of the Ministry of Environmental Protection, in 2010, the national industrial solid waste generation amounted to 2,409.435 million tons, of which hazardous waste generation amounted to 15.868 million tons, and the comprehensive utilization amount (including storage amount in previous years), storage amount, and disposal amount were 976.8 10,000 tons, 1.663 million tons, and 5.127 million tons. It can be seen that with the rapid growth of my country's economy, the production of industrial waste and hazardous waste continues to rise, and the corresponding disposal facilities are far from meeting the demand. [0003] There are various ways to dispose of hazardous waste. Among them, the met...
