Description

Drying device for food waste {DEVICE OF DISTILLATION FOR GARBAGE}

The present invention relates to a dry distillation apparatus for food waste, characterized in that a large amount of food waste is distilled with a small amount of fuel by reusing the same dry distillation gas as a dry distillate fuel.

The problem of daily disposal of food waste in large amounts of urban dwellings is very serious. Conventional methods and apparatuses for fermentation of food are known, and as a prior art related to the present invention, a method and apparatus for fermenting food waste of Patent No. 20143 (published on March 25, 1999) are disclosed. The patented fermentation vessel equipped with a stirrer and a dust collector to collect the dust generated in the fermentation vessel and a deodorization tower to remove the odor by incineration heater in combination to form a fermentation treatment at a temperature of 120-130 ℃.

However, it is difficult to propagate harmful bacteria generated during fermentation and completely remove odors, which not only causes environmental pollution, but also takes long time for fermentation treatment, making it difficult to efficiently process a large amount of food waste and not easy post-treatment of fermented substances. There were various problems.

The present invention is to correct this problem in the prior art and hygienic dry distillation of a large amount of food waste in a short time, the heating chamber and the combustion tube is formed in a plurality of tanks and the heating furnace for supplying the heat source of dry distillation equipped with a burner, the agitator in the distillation chamber It is installed and formed in the main wall of the drying room by the hot air passage to dry the food waste and the cyclone dust collector associated with these heating furnace and the drying passage and conduit to form a dust collector that collects the steam and dust generated during drying It was.

Therefore, by supplying 400 ~ 450 ℃ hot air formed by the burner in the heating chamber to the drying furnace, organic material of food waste put into the drying chamber is dried at a high temperature for a short time, and at this time, evaporation of water, gas, etc. The dry gas collected at the same time to collect materials and dust from the cyclone dust collector is recovered to the heating chamber and reused as dry fuel, so that more food waste can be efficiently and sanitized by less fuel. It is.

As shown in FIG. 1, a heating furnace A for supplying hot air necessary for the drying of food waste and a drying furnace B for drying the food waste by hot air of about 400 to 450 ° C. supplied from the heating furnace and moisture, etc. Composed of a dust collector (C) for collecting evaporated matter and dust and recovering dry gas.

The heating furnace (A) has a heating chamber (1) and two rows of combustion tubes (1a) (1b) (1c) formed in three stages in a zigzag manner and connected by a hole (a) (b) (c). A burner 1f using a known oil or gas is provided on one side of the chamber 1 to burn fuel.

In the distillation furnace (B), a normal stirrer (2x) is installed inside the distillation chamber (2), where the distillation is carried out while stirring the food waste to be distilled, and inside the lower circumferential wall (2a) of the semi-cylindrical distillation chamber (2). A passage 2c is formed so that the hot air supply pipe 4 associated with the upper combustion tube 1c of the heating chamber 1 is in contact with one end of the hot air passage 2c, and the other end of the hot air passage 2c is blown. The hot air is circulated and heated in association with the lower combustion pipe 1a of the heating chamber 1 through the reflux pipe 4a via the fan 5. In addition, one end of the auxiliary pipe 4b in contact with the upper combustion pipe 1c of the heating chamber 1 is guided into the distillation chamber 2 to supply flammable hot air into the distillation chamber of food waste.

In addition, a damper 2f operated by an electrical signal of the temperature and pressure sensor s is installed at the upper outlet 2b of the distillation chamber 2 to automatically open and close the exhaust.

The dust collector (C) is formed of a cyclone dust collector (3) and the discharge pipe (4c) installed in the distillation chamber (2) is in contact with the inlet (3a) of the dust collector (3) via the blower fan (5a), Dust and the like are collected and the recovery pipe 4d connected to the outlet 3b of the dust collecting container 3 is led to the lower combustion pipe 1a of the heating chamber 1 to reuse dry gas as dry fuel. It is.

The present invention as described above is put in the food waste to be treated in the distillation chamber (2) of the distillation furnace (B) and sealed. Combustion gas combusted in the combustion chamber 1 by burning the fuel by the burner 1f in the heating chamber 1 of the heating furnace A while driving the agitator 2x by the power means not shown to stir the food waste. Through the cylinder (a) through the lower combustion tube (1a) flows into the intermediate combustion tube (1b) through the tube (b) and then completely burned while passing through the upper combustion tube (1c) through the tube (c) of the internal pressure Due to the increase, heat is supplied to the distillation chamber 1 through the hot air passage 2c of the distillation chamber 2 of the distillation tank B through the supply pipe 4a. Supply. The hot air passing through the hot air passage 2c is refluxed by the blower fan 5 to the lower combustion pipe 1a of the heating chamber 1 through the reflux tube 4a and reheated. On the other hand, hot air including a combustible gas is directly supplied from the upper combustion pipe 1c of the heating chamber 1 into the dry storage chamber 2 through the auxiliary pipe 4b.

The temperature inside the drying chamber (2) is carbonized in the carbonized state because the temperature of the organic matter of the food waste is burned or the supply of air is insufficient. At this time, a large amount of steam, interstitial gas, and dust generated through the exhaust pipe (4c) (C) flows into the dust collecting container (3), condensation of moisture, etc., dust and the like is collected quietly downward according to the cyclone theory, and dry gas is heated through the recovery pipe (4d) (1) of the heating chamber (A). It is recovered to the lower heating tube 1a of and reused as dry fuel.

When the internal temperature and pressure of the distillation furnace B are raised to the set value, the damper 2f is opened by the electrical signal of the sensor s, and the gas in the distillation chamber 2 is discharged to the outlet 2b.

Since the food waste stirred by the stirrer 2x is easily evaporated and carbonized while moisture is evaporated by high heat, the growth of harmful microorganisms is blocked and generation of odors is suppressed.

When the dry distillation is finished, the heating is stopped, the carbonized dry distillate is taken out, and the food waste to be treated is put into the dry distillation chamber and repeatedly distilled.

Since the food waste is dried and dried by high temperature, odor generation is suppressed first, and the growth of germs harmful to the human body is blocked.

In addition, since the structure of the furnace consisting of the heating chamber and the combustion tube is simple and the combustion operation is good, simultaneous dry gas can be recovered and reused as dry fuel, which can efficiently supply the heat energy required for the drying. Larger amounts of food waste can be carbonized.

Dry matter of processed food waste is light and small in volume and carbonized and does not smell bad, so it is easy to post-treatment and does not cause pollution.

In addition, the treated material can be used as an adsorbent for sewage treatment, can be sprayed on orchards or crop soils to suppress the growth of bacteria or insects harmful to crops and can be used as a beneficial fertilizer for plants.

In addition, the dry distillation can replace the fermenter of the patented device of the present invention, which has been patented by the present inventors, thereby facilitating the economic availability of the device. In addition, once installed, there are almost no breakdown points, and it is easy to operate, so that anyone can operate and hygienically manage a large amount of food waste.
