Abstract

“VIBRATING HEAT EXCHANGER EQUIPMENT FOR LOW TEMPERATURE CONVERSION FOR ORGANIC WASTE TREATMENT AND ORGANIC WASTE TREATMENT PROCESSING THROUGH THE USE OF VIBRATING HEAT EXCHANGER EQUIPMENT FOR LOW TEMPERATURE CONVERSION” The present invention relates to a reactor and the respective procedure that employs it, for processing lipid and protein rich organic waste using the technique of low temperature conversion, the reactor also being used for the treatment of waste with organochlorine contaminants and processing lignocellulosic organic waste, the main products being generated during the processing of oil and coal. The reactor (1) essentially consists of a single bypass tube shell-type heat exchanger, with several heating tubes (7) of cylindrical shape and is mounted so that the axis of the heating tubes (7) are positioned vertically with a triangular distribution, which facilitates the construction of devices with circular section and facilitates the distribution of the raw material. The reactor (1) has arrangements for continuous operation, due to a system which promotes the equipment (1) vibration (13), facilitating the loading of raw material and unloading of coal, as well as a condensing unit (27) of the vapors produced in the process, in order to obtain the fuel oil.

AI Technical Summary

Benefits of technology

The heat exchanger machine has multiple internal heater pipes that are positioned vertically and triangularly distributed, which allows for better use of space inside the reactor. The variation in the number and length of the heating pipes allows for the construction of machines with a wide working range extending from 2 t / day to 300 t / day or more. This feature is useful for manufacturing machines that can handle a range of production rates.

Problems solved by technology

On the contrary, if chlorinated organic contaminants are present in the material being processed, there is significant destruction of these compounds during the conversion.

The main difficulty for effectiveness of the pyrolysis process for processes with indirect heating is to solve the problem of heat exchange that arises due to the coal layer that is formed in the vicinity of the inner walls of the reactor and which is a material of low thermal conductivity.

The classical solution for this issue is the use of rotary ovens whose constant revolution continuously removes the layer of raw materials in contact with the top of the oven, but there is always the issue of the high cost of such equipment, which requires dynamic sealing systems to ensure the hermetic conditions required by the process.

The limitation of this type of equipment is the manufacture of machines for large capacities, as there are constructive limits to the axis length.

The biggest challenge to achieve performance in these systems is to provide an efficient heat exchange between the heating medium and the raw material in process; that is because the coal that is formed is a thermal insulating material.
