Description

Technique and device for treating and utilizing excrement and urine and professional factory

When people eat the coarse cereals, the excrement is always contained, the odor is not good, particularly, the toilet becomes an environment-friendly difficulty in dense and luxurious places of the human smoke, the coarse cereals are absolutely not feasible to be cancelled, and the coarse cereals are polluted. The invention aims to properly solve the big problem, is smelly and tasteless and harmless, and changes waste into valuable.

The principle of the invention is characterized in that: [1]the excrement pit adopts a barrier-free sealing technology, so that the excrement pit is thoroughly bottomed, isolated and tasteless, 2, excrement and urine are packaged and centralized for treatment, a sealed filter press is used for separating the excrement and urine, 3, the urine disappears in special chemical treatment and generates electricity, 4, dry excrement slag is hermetically combusted and generates electricity, and ash is used as agricultural fertilizer, so that the excrement pit is sterile and harmless. The main technical properties are as follows: [1]1 cubic meter of excrement and urine can generate about 90 kilowatts, 2 the whole process from use to centralized treatment of the excrement pit is odorless and harmless, and the cost for treating 1 cubic meter of excrement and urine is less than or equal to 1 yuan.

Through domestic and foreign search, no relevant technology is found. Fig. 1 is a structure of an environment-friendly toilet, fig. 2 is a water film sealing structure, fig. 3 is a cross-sectional view from a-a of fig. 2, fig. 4 is a general view of utilization of feces and urine (a treatment and utilization professional plant), fig. 5 is a technical view of chemical treatment of urine, fig. 6 is a cleaning and adsorbing device for feces combustion smoke, and fig. 7 is a cross-sectional view from B-B of fig. 6.

The device of the invention consists of water film sealed toilet pits 2 and 4, a sealing filter press 13, a urine treatment furnace 14 and excrement slag incineration flue gas washing equipment 12.

The water sealing technology (fig. 2 and 3) is an obstacle-free sealing method: the excrement and urine can freely pass through the water film from top to bottom and fall into the excrement containing port 2 and the urine containing port 4, the odor of the excrement and urine is tightly sealed by the water film (see figure 3), 8 is a water film jet hole (a plurality of jet holes), 10 is a water film collecting channel, the water film 9 is continuously and uninterruptedly sprayed, the water of the water film is recycled, and 11 is a circulating water pump of the water film. 5. 6 is the outer wall and the inner wall of the water film groove, 3 is the foot brick of the excrement pit, 7 is the excrement gathering port, 1 is the outlet (figures 1, 2 and 3), the excrement gathering port and the outlet are collected and packaged, the packaged excrement gathering port and the packaged excrement gathering port are sent to an excrement treatment plant for unified treatment, and the treatment and recycling procedures are shown in figure 4:

the first step is as follows: the excrement and urine are separated by a sealed filter press 13, the urine is conveyed to a urine treatment furnace 14 by a pump and a pipeline, and the dry residue is conveyed to a sealed incinerator.

The second step is that: referring to FIG. 5, air (N) is introduced into the lower pipe inlet 15 of the urine disposal furnace 14₂+O₂) 24 is driving fan, N in air₂And O₂Under the action of the microwave plasma generator 26, the air is ionized and undergoes a chemical reaction: under the action of a catalyst molybdenum silicide 16 in the furnace, NO reacts with urine steam: the reaction temperature is 300 ℃, and the reaction temperature is provided by an electric heating wire. 18 is a urine steam generator, 17 is a steam spray tube(s), as shown in FIG.5, 19 is a hydrogen-passing molecular sieve which passes the product (H) in the above reaction formula₂+NO₂) H in (1)₂Separated and conveyed to a hydrogen combustor 20 and a gas turbine generator 21 for power generation, and hydrogen is combusted and reacted in the air: the generated water vapor flows out of the outlet 23 of the condenser 22 and is then transported to the next process (fig. 4 and 5). 25 is NO regenerator, NO₂Absorption by water: . Nitric acid is a by-product.

The third step: when the dry excrement residue is incinerated (the incinerator is not shown), the fume is smelly and contains health-harmful components, and the dry excrement residue needs to be washed. Some branches are added to support combustion during burning. The flue gas scrubbing apparatus 12 (fig. 6) comprises 8-10 layers in a cylinder, wherein each layer is provided with sand particles 28 on a wire mesh 30, and the bottom view is shown in fig. 7. 33. 34 is the cavity passageway, and 29 is oblique baffle (fig. 6), and this kind of multilayer structure makes the filtration washing area increase 8 ~ 10 times, effectively improves the absorption washing effect. The washing process comprises the following steps: dirty flue gas enters from the cyclone inlet 31, the flue gas is divided into 8 paths, the 8 paths of flue gas flow upwards through the sand layers, water is sprayed above the sand layers, the water flows of the paths are collected, dirty water is discharged from the outlet 32, and then the dirty water is conveyed to the steam generator 18 through a pump and a pipeline for cyclic application. And 27 is a dehydration layer.

In summary, the following steps: after separating the feces from the urine, the feces are separately treated: (1) the urine disappears after being treated to generate electric energy and clean water (used by the user), and (2) the excrement disappears after being treated to generate electric energy and ash (agricultural fertilizer). And (4) conclusion: the waste is recycled, the waste is changed into valuable, and the deodorant is smelly, tasteless and harmless and is a hundred percent environment-friendly facility.

A small amount of perfume (perfume) is added into the water quality of the water film, so that the environment is protected and the water film is filled with delicate fragrance. For a separate urinal, a water film seal may be provided according to the method of figures 2 and 3.
