Embodiment 2

[0039] A method for hydrolysis treatment of kitchen waste, the treatment method is carried out using the kitchen waste hydrolysis treatment device described in Example 1, specifically comprising the following steps:

[0040] 1) Put the kitchen waste into the hydrolysis high-pressure tank through the feed port of the hydrolysis tank, close the exhaust pipe of the hydrolysis tank, close the oil discharge port, close the sewage inlet valve, close the discharge port of the hydrolysis tank, and close the hot dry air inlet. When the material in the hydrolysis high-pressure tank reaches 10% of the total volume, open the hot dry air inlet, adjust the temperature of the hot dry air to 115°C, and open the exhaust pipe of the hydrolysis tank at the same time.

[0041] 2) When the material in the high-pressure hydrolysis tank reaches 55% of the total volume, close the exhaust pipe of the hydrolysis tank, increase the temperature of the hot dry air to 125°C, and after the pressure in the hi...

Abstract

The invention relates to a method for hydrolysis treatment of kitchen waste. The device used in the method includes hydrolysis high-pressure tank parts, sewage treatment parts and screening parts; the method includes dry air stirring of materials, periodic high-pressure hydrolysis, drying treatment, and sewage discharge. And processing and material screening and other steps. Through the arrangement of the above-mentioned device and the arrangement of steps, the efficient separation and treatment of kitchen waste is realized.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for hydrolyzing kitchen garbage. Background technique [0002] Since the main body of food waste is a mixture of sewage and solid waste, and because it contains a large amount of organic matter, it will breed a large number of bacteria and other microorganisms during the temporary storage and transfer process, so the treatment of food waste needs to be minimized Transshipment and storage time may require subsequent treatment after deodorization and disinfection of food waste. However, deodorization and disinfection generally require the addition of disinfectants, and the addition of disinfectants also prolongs the follow-up treatment process. [0003] At present, there are studies using high-pressure high-temperature steam treatment method to treat kitchen waste. The high-pressure high-temperature steam treatment method mainly uses steam at 120-210°C under a pressure of ...
