Vibratory heat exchanger unit for low temperature conversion for processing organic waste and process for processing organic waste using a vibratory heat exchanger unit for low temperature conversion

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.

Benefits of technology

[0030]The waste material that is not volatilized is the coal. The coal from all heating tubes is collected in the conical bottom (bottom funnel) of the reactor from where it is continuously removed. In order to avoid problems of compression in an unload nozzle, there is a lower taper which limits the amount of material that is addressed to the nozzle. In order to control the flow of incoming and outgoing solids while minimizing the escape of gases generated in the process, the equipment has lock-type valves or rotary-type valves (or a similar mechanism) in the raw material supply upper nozzle and coal unload lower nozzle.

[0031]The most important feature of this invention patent application is that, in order to enable the supply of raw material and unload of coal continuously, the equipment is provided with a system which promotes the vibrating movement of the equipment. The vibrating movement gives important functional properties to the invention, such as, for example, promoting the distribution of the raw material poured into the top mirror of the reactor so that there is a tendency for the uniform filling of all heating tubes; increasing the efficiency

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
