Description

DESCRIPTION

CLF MODIL motorized mechanical type bioxidative system for the transformation of liquid and solid wastewater

Invention background

The present invention is part of the technical sector of the mechanical systems of industrial facilities suitable for the elimination of liquid and solid wastewater, biogas and biomethane digestates, zootechnical and agri-food wastewater using natural transformation systems into organic substance. This consists of the transformation of liquid and/or solid wastewater, preferably but not limited, into palatable materials with the use of plant materials with low moisture content, i.e. straw, wood chips, etc. Currently, wastewater management is carried out through very complicated, energetic or undisciplined systems, sometimes causing environmental contamination of aquifers, producing bad odors and inconvenience for the community.

The objective of the present invention is, therefore, to propose a bioxidative system of a motorized mechanical type, which is capable of mixing the wastewater of the substances described above so that they are treated without the addition of particular chemical substances and that does not release bad smells.

Summary of the invention

In the known art there are mechanical plants that deal with the treatment of biological wastewater, but they have enormous disadvantages because they cannot produce a humified, disinfected homogeneous and, above all, odorless compost. Unlike the installation of the machine proposed in the present invention, it uses a ventilation system directly on the organic wastewater during the transformation operations into an air conditioner using air blowers, which we will analyze better below, placed directly on each one. of the paddle holders of the worm screws (11) that work synchronously within a tank (12) (34) into which the residual water is submerged by means of a feed pump (13).

The feed pump (13) is located between two concrete bulkheads (14) (15), so that the pump is separated from both the containment tank and the outside.

The feed pump tube (13) is closed not limited by a steel plate (16) (17), by means of anchor bolts (18) (19).

At the ends of the steel sheets (16) there are two rubber bulkheads (20) (21). These partitions prevent the escape of annoying odors.

The feed pump (13), therefore, takes the wastewater directly from the feed channel to introduce it directly into a pipe (22) that is fitted with a liter counter (23). The liter counter is necessary to know the amount of wastewater that will be inserted into the tank to be processed. The pipe runs successively across the entire width of the tank supported on a beam (24).

The pipe during its stroke, that is, approximately halfway up the beam, branches into two smaller diameter pipes (25). The two pipes are initially introduced into two different solenoid valves (26) (27) (whose operation we will see below), to continue their journey until entering a catenary (28). The catenary is located above the right beam (24) in a horizontal direction. The catenary, located precisely on the right beam, is hooked by a drag arm (29) to the castle (30).

The two pipes (25) enter the interior of the castle to respectively reach the two right (31) and left (32) fan spreading systems.

The fan systems are placed to the right and left of the castle and, respectively, in front and behind the worm screws.

The fan systems (31) (32) preferably, but not limited to, made of steel have the functionality of spreading wastewater from the two pipes (25).

The worm screws are respectively connected to the castle (30) of the machine directly to the non-limited electric gear motors (35) (36), while a blower (37) always located in the castle (30) blows the air into the ventilation system. ventilation to each blade of the worm screws.

To better understand the operation and, therefore, the mechanism of the worm screws, keep in mind that the worm screw is formed by a paddle holder (45) and a paddle (44), fixed on the lower hollow shaft (46). .

A channel is made in the pallet holder for the air outlet (48). A connecting flange (47) is fixed to the upper part of the hollow shaft. As we will better specify below, the channels in the paddle support are made so that the air escapes to activate and keep the biological process active, in addition, the paddles have the function of better homogenizing the plant materials contained in the tank together with wastewater.

The worms, as described above, are connected to gear motors, which allow their rotation. The horizontal and vertical movement of the worm screws is carried out through an electrically powered hydraulic control unit (49). The hydraulic control unit drives four hydraulic pistons (50 (51) (52) (53) of two different sizes.

The hydraulic pistons are fixed to the castle frame (30) both at the top and bottom by iron supports and act on the worm platform by means of two rotation bolts fixed on the lower castle platform. These pistons, therefore, allow the rotation of the worm platform (55) both horizontally and vertically.

To now understand how the air is channeled in the augers, it is considered that inside the castle (30) there is an electric blower (56) with two channels (suction and compression). This electric blower sucks the outside air from the suction channel (57) and then introduces it into the compression channel (58).

The compression channel of the blower is introduced into a main pipe of predefined diameter (59), which reaches a rectangular tank (60) placed horizontally on the main platform of the screws. Pipes of smaller diameter branch out from the rectangular tank depending on the number of screws, which can be 3 or 5.

In this way, the compressed air is channeled from the tank to the smaller diameter pipes that are introduced inside the cylindrical supports of the worm screws themselves (61).

The air in this way reaches the interior of the upper auger and is pushed down into it until it reaches the part of the lower hollow shaft.

In this way, the air leaves the channels of the paddle holder (62).

Described so far, each mechanical component of the Found is necessary for greater understanding, given its complexity, to detail its use at the time it comes into operation. Assuming that the tank (34) has already been filled with a defined amount of plant material and that the castle (30) is in the zero position (apex of the tank on the side of the PLC control panel) and that the entire machine is completely turned off, we can describe its movements in the tank and detail its mechanical functions.

Manually, through an electronic system (PLC), the machine is programmed and started. In this way, the gear motors contained in the castle are activated, allowing the worm screws (46), which are initially in a horizontal position, to rotate synchronously. The lower axes of the endless screws (46), which rotate horizontally to the tank by means of a hydraulic control unit (49) through pistons (50) (51) (52) (53), descend in a vertical position with respect to the tank (12). The aeration system comes into operation through the blower (56) that pushes the air into the lower shaft of the worm screws (46) and then into the channels of the pallet holder (62). The wastewater flowing along the pipe (22) will initially find the left solenoid valve (26) closed, to allow the wastewater to flow only in one of the two pipes (25) to exit only on the right side of the right recreation system (31). At this point, the movement of the castle is activated in the transverse direction to the tank by sliding the catenary (28) along the axis of the beam (24) by means of the dragging arm (29).

When the castle is close to the other end of the beam, the electronic system (PLC) will initially block the solenoid valve on the right, so that no residual water comes out in the right spreading system, and a non-electrically limited gear motor is activated. (41) which allows the bridge crane where all the machinery rests, that is, the castle, to move longitudinally to the tank. This displacement is carried out gradually, that is, exactly equal to the width of the worm screws. Completely automatically and given that the worm screws rotate non-stop during machine operation, the PLC system orders the sole solenoid valve on the left (26) to open and the solenoid valve on the right (27) to remain closed, since in this way it will arrive through one of the two pipes (25) or from the left pipe for the precision of the flow of wastewater that will fall into the left spreading system (32). This is so that the castle resumes its career in the opposite direction to the tank and always transversally. The movement of the castle transversely and the bridge crane longitudinally continues in the system just stated until the entire area of the tank (34) is covered and then returns to the work-only mode without spreading the wastewater until the waters are homogenized. waste with the plant materials contained in the tank is completed in a predefined time.

The machine can also perform only the processing cycle (NO SPREAD) to homogenize and aerate the material inside the tank (PLANT MATERIAL AND WASTEWATER).

The present mechanical system achieves through its mechanisms an oxidative decomposition of the organic substance operated by aerobic microorganisms; Compared to known natural processes (manure, leaf litter), such decomposition is characterized by a greater speed of transformation and a notable production of heat.

Moving and aerating the biomass (coformulant) with the wastewater (formulant) triggers an aerobic process that feeds the formation of naturally present microorganisms, thus promoting and selecting the optimal biodegradation conditions of the organic substance in the wastewater, digestates, feces and urine with a strong development of heat and without emissions of noticeable odors.

The straw or other plant matrices, in addition to playing the role of structuring for the biological process, acts as a natural biofilter for emissions, since in the bed a bacterial microflora capable of degrading, mineralizing them, the molecules of the materials is selected and developed. contaminating compounds (organic and inorganic), ensuring that emissions and annoying odors do not develop.

In the aerobic process implemented by the plant, the transformations that affect the biomass produce ecologically “sustainable” organic compounds: organic matter/organic carbon --^HUMIC and FULVIC ACIDS, total nitrogen/organic nitrogen --^gaseous elemental nitrogen, compounds sulfides -^ assimilable water-soluble sulfates.

The process is biological; The process allows the reduction of the polluting load by reducing/preventing emissions of greenhouse gases and acidifiers into the atmosphere (which would occur in storage and possible successive alternative treatments). The technology used by this Trovato uses exclusively non-electric motors in all its process phases, not emitting CO<2> into the atmosphere during the treatment of effluents and digestates and reduces the nitrogen load through nitrification/denitrification, process implemented in biological purification.

In addition, it allows the reduction of the volumes of wastewater that will be distributed in the fields or stored in tanks. In fact, it eliminates odors even during processing. Straw, in addition to playing the role of structuring for the biological process, acts as a natural biofilter for emissions, since it selects and develops a bacterial microflora capable of degrading, mineralizing them, the molecules of polluting compounds (organic and inorganic), ensuring that unpleasant emissions and odors do not develop.

The Found also allows the sanitization of the final product (therefore, the inactivation of weed seeds and pathogenic organisms) since the temperature is maintained at values above 60° C for at least 5 consecutive days (as required by legislation). .
