Description

Pollution prevention device of garbage fermenter

The present invention relates to the production of feed (raw material) or compost by crushing and dehydrating food waste containing a large amount of water and then fermenting and drying the fermenter for a predetermined time in the fermenter, and more specifically, in the fermentation of food waste. The present invention relates to a pollution prevention device for food waste fermenters which removes generated wastewater, waste gas, and odors to prevent pollution and environmental pollution.

Due to the increase in population, the improvement of living standards, and the diversification of economic activities, the generation of various wastes continues to increase, and the disposal of such wastes is not only at the level of individual individuals but also at the level of local governments and countries. It was causing various problems such as the problem of disposal cost, environmental pollution and social conflict.

One of the most representative of these wastes is food waste. In particular, the foods preferred by Korean people are foods such as soup and soup, which contain a lot of water. Since the moisture content of the garbage reaches 85%, it is difficult to reduce the amount by more than 10% even when compressed and dehydrated.

Therefore, the fermentation treatment for a certain period of time after being put into the fermenter in the state of containing a large amount of water, sewage is generated in this process, difficult unbearable odor that causes respiratory pollution, and various harmful gases (dioxin, etc.) are emitted. However, these odors and harmful gases were released into the atmosphere as the main cause of pollution and environmental pollution.

In addition, in order to ferment the food waste containing a large amount of water, a separate heat source (electric heater, or gas heater), etc. must be operated to heat the fermentation tank, thereby causing additional fuel costs.

In order to solve this problem, a odor removal device has recently been proposed to remove odors. However, the odor removal device is very expensive and can remove odors. However, the wastewater generated here cannot be discharged as it is not properly purified. There was an unreasonable problem that had to go through a separate purification process.

Here, the reason why the condensation tank 11 and the deodorization tank 13 are formed integrally with each other is to make the structural device more compact by reducing the arrangement area as much as possible.

The fermentation tank (2) is connected to the condensation tank 11 and the suction line 20, the high-temperature water vapor and various harmful gases, odors emitted during fermentation are supplied to the condensation tank 11 through the suction line (20) The condenser 30 is installed in the condensation tank 11 to undergo a condensation process.

Since the condenser 30 is installed inside the condenser tank 11 to block the air from the outside, it is difficult to cool the refrigerant on its own, so that the refrigerant is cooled by using external cold air in a separate condensation unit 14 installed outside. Then it is introduced into the condenser 30 installed inside the condensation tank (11).

Therefore, the condenser 30 condenses high temperature water vapor emitted from the fermentation tank 2 and various harmful gases and odors to generate condensed water to remove water contained in the high temperature water vapor. The condensate generated in this process is discharged to the outside through the condensate outlet 11a installed on the bottom surface of the condensation tank 11, and the condensate is water contained in the water vapor, so even if it is discharged to the outside without additional purification treatment, There is no problem.
