Technical Field

The invention relates to the field of garbage treatment, in particular to a garbage hydrolysis method.

Background

At present, municipal waste is mainly treated by landfilling or incineration in a waste incineration power plant.

The garbage entering the garbage incineration plant contains a large amount of non-combustible construction garbage including cement blocks, bricks, soil and sand stones, and the non-combustible construction garbage enters the garbage bin along with the household garbage, so that a fermentation area of the garbage bin is occupied, and the storage amount of the household garbage is reduced; the domestic garbage enters the incinerator along with fermented domestic garbage for incineration at the later stage, but the building garbage cannot be combusted, so that not only can heat not be generated, but also the heat generated after the domestic garbage is combusted is absorbed, the heat efficiency of the boiler is reduced, and the generated energy is influenced; the construction waste absorbs a large amount of heat in the incinerator, the temperature is very high, and along with behind the slag by the discharge boiler, need cool down with a large amount of water, cause the increase of water consumption, water waste.

Therefore, the garbage entering the factory is effectively decomposed, so that the efficiency of the incinerator can be improved, and the energy consumption is reduced.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: a method for hydrolyzing garbage is provided.

In order to solve the technical problems, the invention adopts the technical scheme that:

a garbage hydrolysis method is based on two-stage sorting water tanks, wherein the first-stage sorting water tank is communicated with the second-stage sorting water tank through a gate valve, water is injected into the first-stage sorting water tank in an initial state, and the second-stage sorting water tank is empty, and comprises the following steps:

s1, discharging the primary garbage into a primary sorting water tank;

s2, waiting for the construction waste in the primary waste to sink to the water bottom and suspending under the water after the cloth paper waste absorbs water; the plastic products and the light domestic garbage float on the water surface;

s3, picking up plastic products and light household garbage floating on the water surface to realize primary sorting;

s4, opening the gate valve to enable water in the primary sorting water tank to flow into the secondary sorting water tank, and enabling cloth paper garbage suspended in the water to flow into the secondary sorting water tank along with the water;

s5, closing the gate valve, and picking up the construction waste staying at the bottom of the primary sorting water tank to realize secondary sorting;

s6, pumping water in the secondary sorting water tank, and enabling cloth paper garbage suspended in the water to be retained in the secondary sorting water tank;

s7, picking up the cloth paper garbage retained in the secondary sorting water pool to realize tertiary sorting;

and S8, ending.

On the basis of the technical scheme, the invention can be further improved as follows.

Preferably, the water in the secondary sorting water pool is pumped out and then is injected back to the primary sorting water pool.

Preferably, the water in the primary water tank is sourced from non-reusable water such as percolate concentrated water, factory outdoor drainage, sewage filtering and the like.

Compared with the prior art, the invention has the following technical effects:

can sort out building rubbish, also can sort out cloth, paper class rubbish, avoid building rubbish to occupy the fermentation space promptly, avoid cloth, paper class rubbish to be cleared away along with building rubbish again and cause the waste.

the second-stage sorting water tank 2 and the water collecting pit 3 are communicated with each other through a 5-mesh filter screen 5;

the bottom of the water collecting pit 3 is lower than the bottom of the secondary sorting water tank 2;

the grab bucket 8 is arranged above the primary sorting water tank 1 and the secondary sorting water tank 2, and the grab bucket 8 can move;

the sewage pump 6 is arranged in the water collecting pit 3. The outlet of the sewage pump 6 is connected to the primary sorting water tank 1 through a water pipe 7.

The garbage hydrolysis method is based on the garbage hydrolysis system and comprises the following steps:

s1, discharging the primary garbage into a primary sorting water tank;

s2, waiting for the construction waste in the primary waste to sink to the water bottom, and suspending under water after the cloth products and the paper products absorb water; the plastic products and the light domestic garbage float on the water surface;

s3, picking up plastic products and light household garbage floating on the water surface to realize primary sorting;

s4, opening the gate valve to enable water in the primary sorting water tank to flow into the secondary sorting water tank, and enabling cloth and paper garbage suspended in the water to flow into the secondary sorting water tank along with the water;

s5, closing the gate valve, and picking up the construction waste staying at the bottom of the primary sorting water tank to realize secondary sorting;

s6, pumping water in the secondary sorting water tank, and isolating and retaining the cloth and paper garbage originally suspended in the water in the secondary sorting water tank by a 5-mesh filter screen;
