Abstract:
The disclosure relates to preventing an oxidizer from overheating using cold side bypass during high input for a VOCs treatment system having a series rotor, which may be used in an organic waste air treatment system. The system includes a thermal oxidizer (TO), a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a first cold-side transporting pipeline, a fourth cold-side transporting pipeline, a first adsorption rotor, a second adsorption rotor, and a chimney. A cold-side proportional damper is installed between the first desorption-treated air pipeline and the first cold-side transporting pipeline, between the first desorption-treated air pipeline and the fourth cold-side transporting pipeline, or between the first cold-side transporting pipeline and the fourth cold-side transporting pipeline, or the damper is installed on the first desorption-treated air pipeline.
Abstract:
The continuous process of the present invention is intended to obtain dry biomass from two treatment steps by drying organic waste. The waste previously sieved and crushed waste are dumped into a first dryer, inside of which temperatures are between 280° C. and 300° C. at the inlet thereof and between 90° C. and 100° C. at the outlet, then passing to a conveyor belt where at room temperature a partial cool-down occurs and the waste is dumped into a second dryer inside of which the temperatures are between 180° C. and 200° C. at the inlet and between 75° C. and 85° C. at the exit, completing the process, during which the interior of the dryers is maintained in negative pressure through exhaust flow and the oxygen content is kept between 5 and 7%.

A process for treating a human remains comprises the steps of subjecting the remains to pyrolysis in a pyrolysis chamber under conditions that convert the particulate material to biochar remains.
Abstract:
The starting point is a process to improve the performance of the incineration of combustible waste material in an incineration chamber, whereby the waste material is conveyed to a burner flame where it is burned with combustion air at a temperature in the range from 1100° C. to 1700° C. [2012° F. to 3092° F.]. On this basis, in order to create a process that allows a capacity increase of installations employed for the exothermal incineration of waste materials, it is proposed according to the invention that at least part of the combustion air is replaced by an oxygen-rich gas having an oxygen content that is higher than that of air and that the oxygen-rich gas is mixed with a cooling medium.
Abstract:
The invention relates to a feeder and method for feeding raw material which comprises plastic to a gasification, pyrolysis or combustion furnace, in which the feeder comprises a screw feeder part and a pneumatic feeder part in order to form a combined feeder for feeding the raw material, the screw feeder part comprises at least a screw to transfer the raw material to the pneumatic feeder part and at least one cooling device to cool the raw material in the screw feeder part, and the pneumatic feeder part arranged after the screw feeder part comprises at least one inlet to supply pneumatic carrier material to the raw material in the pneumatic feeder part for forming a mixture of the raw material and pneumatic carrier material.
Abstract:
A corn-burning stove provides cooling for the corn in-feed auger and other adjacent components by combustion inlet air flow patterns. The inlet air flow transports pellet fuel through a distance within the fire pot which varies responsive to the flow rate of the inlet air flow. A fire pot and agitator ensure, in combination with the inlet air flow, complete burning of the corn, with almost no ash production and while avoiding the formation of clinkers. The agitator is toothed, having teeth closely adjacent the burn pot for moving burning corn kernels or solid pellets across the fire pot. Retractable ignitors have handles and furnace function interlocks. A process control is associated with the corn burner that includes some logic, including interlock, power control, speed controls, sensing inputs/devices, and user interface.
Abstract:
The present invention provides a method for processing wastes containing a large amount of water and a method for processing leachate from industrial wastes. Specifically, the present invention provides a method which comprises maintaining reduced pressure in the dryer equipped with a stirring means, feeding wastes containing a large amount of water to the dryer, stirring the wastes while blowing refrigerated air at -20.degree. C..+-.5.degree. C. to the dryer, and drying the frozen moisture portion of the wastes by sublimation. Air heated at 80.degree. C.+10.degree. C. can be used instead of refrigerated air to dry water of the wastes by evaporation. The present invention also provides a method for processing leachate which comprises pooling leachate industrial wastes and burned ashes, and utilizing the leachate to absorb wet-type toxic gas, thereby confining the leachate within the waste treatment plant. The present invention therefore make it possible to process wastes containing a large amount of water, which have been a problem in the incineration by the conventional methods, by using the potentioal heat of the waste gas from the incinerater. The present invention also provides an effective means to prevent environmental contamination because leachate is confined in the waste treatment plant.
Abstract:
A method of incinerating pretreated industrial waste, according to which the wastes conveyed to the incinerator in containers is pretreated either by deep-freezing the wastes or by volatilizing the wastes under exclusion of air, or by mixing the wastes with substances of addition or with leaning substances, e.g., mud, ash, sand, wood shavings, whereupon the thus obtained wastes, either reduced in size or in volatilized condition are fed into the fire chamber of the incinerator.
Abstract:
An incinerator plant for burning pre-treated industrial wastes which in barrels or the like with different contents and of unknown composition are fed into the incinerator plant, the pretreatment of the pre-treated industrial wastes being effected by deep freezing the barrels with contents or the barrel contents or by evaporating the barrel contents under exclusion of air while supplying evaporating heat directly or indirectly or by mixing the barrel contents with substances of addition or leaning substances. The incinerator plant includes means for sorting the barrels, emptying same, comminuting the barrel contents and the barrels, dosing means for dosing the waste material to be incinerated to a combustion chamber which latter is followed by a post combustion chamber and by a flue gas cooling device as well as by a flue gas washing device and a flue gas heating device with flue means.
Abstract:
A method of treating human remains prior to burial or other means of disposal comprises the steps of freezing the remains and size reducing the remains to particulate matter. The freezing step includes the steps of placing the remains in a freezing chamber, charging the chamber with a gas, and circulating the gas in a loop between the freezing chamber and a cooling device. The gas cooling device is adapted to cool the gas to a temperature below −100° C. while maintaining the gas in a gaseous form. The gas cooling device may include a heatsink and a means for cooling the heatsink, wherein the circulating gas is cooled by being brought into contact with the heatsink.
