Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger that cools dry distillation gas generated during dry distillation of combustible materials and recovers combustible materials.

The amount of waste generated continues to increase year by year as industry develops and people's lives improve.

Recently, resource recycling has been actively used as an effective means of processing these wastes. The present invention provides an effective technology for reusing this resource, that is, a unique technology for a heat exchanger that efficiently extracts fuel from waste dry distilled gas.

When dry distilling waste, etc., a larger amount of floating dust than expected enters the heat exchanger that cools the dry distilled gas and recovers combustible oil, and this dust adheres to the oil that has condensed on the cooling pipes and side walls of the heat exchanger. However, various troubles have occurred, such as lowering the cooling efficiency of the heat exchanger and furthermore, the inside of the heat exchanger being clogged by the accumulated dust.

For this reason, the equipment had to be stopped each time the removal work was performed, which was difficult and required a lot of time and effort. The present invention does not require a separate dust removal device for processes other than dry distillation installation, and is equipped with a mechanism that can continuously cool dry distillation gas and recover combustible oil without having to stop the device each time dust removal work is performed. This relates to a fuel exchanger.

The details will be explained below based on the drawings showing one embodiment.

1 is a heat exchanger main body, and 2 is a dry distillation gas inlet hole connected to a dry distillation furnace (not shown).

3 is a baffle plate installed opposite to the dry distillation gas inlet hole 2 in order to cause dust in the dry distillation gas to fall downward;
is an oil layer condensed from the dry distilled gas at the bottom of the heat exchanger 1, and 5 is a hatching machine installed near the heavy oil discharge port 6 in order to make the properties of the oil layer uniform.

7 is a heat exchanger inlet cleaner device installed above the dry distillation gas inlet hole 2 to remove dust adhering to the side surface of the baffle plate 3 and the heat exchanger inlet side wall; This is the oil outlet.

9 is a group of cooling pipes for lowering the dry distillation gas to the condensation point of oil and separating the oil from the dry distillation gas.

Reference numeral 10 denotes a cooling pipe cleaner device installed at the top of the cooling pipe group, and the cooling pipe cleaner device is slid up and down by an operating mechanism (not shown) such as a fluid pressure cylinder, and is attached to the cooling pipes and the surrounding inner wall. It has a mechanism for scraping off the dust to the oil layer 4 at the bottom.

Reference numeral 11 denotes an outlet for the so-called dry distilled gas from which oil has been removed, which is provided on the opposite side of the dry distilled gas inlet hole 2.

Reference numeral 12 denotes a scraping device for collecting high-quality heavy oil and dust deposited at the bottom of the oil layer 4 into the car oil outlet 6, and 13 is a fluid pressure cylinder connected to the scraping device.

The heat exchanger ≠ heat exchanger according to the invention described above can be used to remove dust attached to the area around the heat exchanger inlet with the cleaner device 7 even when there is no dust removal device in the process before the heat exchanger ≠ heat exchanger or when dust is not sufficiently removed by the dust removal device. The dust adhering to the cooling pipe group 9 and its surrounding inner walls is removed by the cooling pipe cleaner device 10, and the dust accumulated at the bottom of the heat exchanger is removed together with the flea oil by a scraping device near the outlet. In addition, the oil collected at the bottom of the heat exchanger can be uniformly illuminated by the heat exchanger 5 and discharged outside from the oil outlet 8, so if a lot of dust enters the main The heat exchanger of the invention is an extremely effective device, and has excellent advantages such as being simple, easy to automate, and capable of continuous operation over a long period of time. It is a heat exchanger that can be widely used to recover energy from various combustible materials such as garbage and general waste, and its usage effects are extremely large.
