Kitchen waste filter liquid oil removal tank and oil removal system thereof

Abstract

The invention provides a kitchen waste filter liquid oil removal tank and an oil removal system thereof, wherein the kitchen waste filter liquid oil removal tank comprises a tank body; a water distribution device and a heating device are arranged in the tank body; an oil level observation device is arranged outside the tank body; the water distribution device comprises a liquid inlet pipe arrangedon the tank body; one end of the liquid inlet pipe is sequentially connected with a bent head and a different-diameter pipe; the top of the different-diameter pipe is provided with a support frame; areflecting plate is arranged on the support frame; a gap is formed between the reflecting plate and the different-diameter pipe. The kitchen waste filter liquid oil removal tank provided by the invention has the advantages that the water distribution is uniform; the energy consumption is reduced; meanwhile, the observation of the oil level in the tank body is convenient; the water content in discharged oil is low.

Description

technical field [0001] The invention belongs to the field of kitchen waste treatment, and in particular relates to a kitchen waste filtrate degreasing tank and a degreasing system thereof. Background technique [0002] The kitchen waste filtrate contains about 3% of animal and vegetable oils and fats, and the waste oil or waste oil contains about 35% to 45% of animal and vegetable oils and fats. As recyclable resources, they need to be effectively separated and recycled. [0003] The kitchen waste filtrate will enter the anaerobic system later, but the grease (long-chain fatty acids) in the kitchen filtrate will inhibit the activity of microorganisms in the anaerobic system, thereby affecting the anaerobic effect. Therefore, it is necessary before the kitchen filtrate enters the anaerobic system. Degrease. [0004] The oil can be fully separated from the water in the filtrate under the heating state (30℃~70℃). Due to the different density, the oil is located in the upper la...

AI Technical Summary

Problems solved by technology

[0008] 1. There is only one drain in the tank, and the solid residue and filtrate are discharged together, which will lead to blockage of the drain pipe for a long time;

[0009] 2. The diameter of the liquid surface at the oil discharge port at the upper end of the tank is the same as that of the entire tank, which makes the grease layer 15 thinner, and a large amount of water in the kitchen filtrate will be brought out during oil discharge, making the moisture content of the obtained grease too large;

[0010] 3. The existing heating method is built-in heating tube heating, which will be corroded by the kitchen filtrate for a long time, and there is a problem of uneven heating;

[0011] 4. The water distribution system of the tank has a single style, which is the water inlet of ordinary water pipes, that is, water pipes with a single diameter. Part of the design between the inlet and outlet of the liquid inlet pipe is at the bottom of the tank. This design will make the filtrate form a horizontal gap at the bottom of the tank. The flow effect is not conducive to the rise of the floating oil. Another part of the tank design is to extend the liquid inlet pipe to the middle and lower part of the tank. 15 is broken, which is not conducive to subsequent degreasing;

[0012] 5. The tank body is in a fully closed state during operation, and the position of the grease layer 15 in the tank cannot be observed intuitively, resulting in incomplete degreasing or high moisture content in the discharged grease
