TH35852A - Continuous pollution control incineration system - Google Patents

Abstract

DC60 (29/11/42) This invented continuous incineration system primarily reduces air pollution and also minimizes water and groundwater pollution. The key points are summarized as follows: - The incinerator can be designed with the required incineration capacity, featuring a waste feeding system coordinated with ash discharge. Placing the oil jet nozzles for combustion at a suitable height at the rear of the incinerator ensures ignition is not hindered. The use of a combustion-assisted fan, drawing air from the waste storage room, also helps to eliminate odors from the waste. - Large ash and/or particulate matter are separated from the incineration gases by a first-stage particulate matter collector, allowing for initial disposal. - A second-stage particulate matter collector is used to further trap smaller particulate matter remaining in the gases from the first stage. A water spray/ceramic ring system is employed to further capture any remaining particles. The system maximizes the removal of gases as much as possible. As the gas exits the second-stage particulate matter collector, it is drawn through a dry adsorption tower by a fan to absorb odors mixed with the gas. Granular activated carbon is used as a catalyst to remove contaminants and components from the gas before it is released into the atmosphere through the chimney, significantly reducing air pollution. Oxygenation of the recirculating water system using an oxygenator and powdered activated carbon further reduces water pollution. This invented continuous incineration system primarily reduces air pollution and also minimizes water and groundwater pollution. This can be summarized as follows: - The incinerator can be designed with the required incineration capacity, with a waste feeding system synchronized with the ash removal system. Placing the oil nozzles for combustion at a suitable height at the rear of the incinerator will not hinder ignition. Using a combustion-assisted fan to draw air from the waste storage room also helps to eliminate odors from the waste. - Separating ash and/or large particulate matter from the gas. This process involves incineration of waste, initially filtered in a stage one dust collector, and then removed as a preliminary step. A second-stage dust collector acts as a supplement to trap any remaining small particulate matter mixed with the gas exiting the stage one. A water spray system/ceramic rings are used to capture as much of this remaining particulate matter as possible. After exiting the second-stage dust collector, a fan draws the gas through a dry adsorption tower to absorb odors. Activated carbon (granular) is used as a catalyst to remove contaminants before the gas is released into the atmosphere, significantly reducing air pollution. Oxygenation of the recirculating water system using an oxygenator and powdered activated carbon further contributes to reducing water pollution.

Claims (4)

1. The continuous pollution control incineration system has the following characteristics: - The incinerator itself comprises a waste feeding system, the arrangement of oil jet nozzles for waste combustion, ash evacuation to synchronize with waste feeding, and an air suction system from the waste storage room to maximize combustion efficiency. - A first-stage dust collector to separate ash and/or large dust particles from the incineration gases, reducing the amount of ash and dust to be separated in the second-stage dust collector. - A second-stage dust collector to capture smaller dust particles still present in the first-stage gases. A sprinkler system or fine spray of liquid is used to further trap remaining dust particles in the gases, and small ceramic rings are used to further trap dust and water, reducing the contamination of the recirculating water. - An Aqua-Jet Surface Aerator to purify and cool the water in the reinforced concrete tank before recirculating it to the second-stage dust collector. 2. The continuous incineration system stipulated in Claim 1 includes a reinforced concrete pit divided into four sections: Section One, Section Two, Section Three, and Section Four, respectively. Sections Two, Three, and Four are interconnected by drainage holes at the top of each section. 3. The continuous incineration system, as per claim 1 or 2, includes the following equipment: - A stage one dust collector, placed above the first section of the reinforced concrete pond. - A stage two dust collector, placed above the second section of the reinforced concrete pond. - A dry adsorption tower, placed above the third section of the reinforced concrete pond. - A gas extraction fan, placed on top of the dry adsorption tower. - An oxygenation unit, suspended above the water in the fourth section of the reinforced concrete pond, secured on all four sides with steel cables to prevent it from moving. 4. The continuous incineration system, as stipulated in claims 1 through 3, shall be equipped with the following equipment: - An incinerator with a hydraulic waste feeding system, oil spray nozzles positioned at the rear of the furnace, ash venting synchronized with waste feeding, and an air suction pipe from the waste storage room to assist in combustion and eliminate odors in the storage room. - A first-stage dust collector to trap ash and/or large dust particles using a centrifugal force generated by a gas suction fan and cast iron screw, separating most of the ash into a reinforced concrete pit where the remaining gas and smaller dust particles are sent to the second-stage dust collector. - A second-stage dust collector to trap any remaining small dust particles mixed with the gas from the first-stage dust collector, using a water spray system and small ceramic rings to absorb and trap as many small dust particles as possible. - A wastewater treatment system with oxygenation and supplemented with the addition of powdered activated carbon to ensure that the water used in the circulating system is always treated and clean.
