Description

The utility model relates to devices for the non-reagent neutralization of liquid and solid fractions of organic waste (medical waste, sewage, bird droppings, feed residues, litter, soil, etc.) from highly pathogenic infections and viruses and can be used in agriculture (on poultry farms and in livestock complexes), in the treatment of medical waste, urban and industrial effluents.

Currently, for the neutralization of organic objects using tools based on various modifications of the thermal method of processing objects. Among them - high-temperature combustion, the use of which pollutes the environment (IN-50 incinerators, Russia); Combined plants using thermal and chemical influences for neutralization (Sterimed, Italy); autoclave plants using thermal action under a pressure of 2-3 bar (Sterifles, France). The above devices have low performance and high specific energy consumption.

Known devices for the neutralization of liquid media using hydropercussion due to the action of pulsed electric current, for example a device for disinfecting deworming and moving wastewater, which issued the USSR author's certificate No. 1713652 (V03C 5/00, published 02.23.1992, BI No. 7) . The device comprises a discharge chamber, in which cylindrical electrodes are coaxially located, and a plurality of simultaneous streamer breakdowns of the electrolyte are carried out on the inner surface of the external electrode provided with a perforated insulating gasket. The shock wave is transmitted to the walls of an elastic pipe, laid coaxially inside the discharge chamber, to the processed fluid.

A device for disinfecting a liquid infected with microorganisms and / or contaminated with organic compounds is known, for which a patent of the Russian Federation No. 2233243 is issued (С02F 1/32, published July 27, 2004). The device contains a UV reactor module, a crude liquid pipeline, a variable speed pump, a UV reactor, in the channel of which there is a pulsed UV lamp capable of emitting one or more pulses of ultraviolet radiation with a wavelength in the UV-C range.

A known installation for the disinfection of animal waste (RF patent No. 2074128 С02F 11/04, published 02.27.1997), including the initial mass storage device with a grinding device, a reactor with a stirrer and a heat exchanger, a starter reactor for the preparation of starter culture necessary for microbiological processing of raw materials, which has an autonomous heating system, through pipelines connected to the accumulator and drain sludge collector and reservoir - heat exchanger, made in the form of "capacity in capacity".

The task to which the claimed technical solution is directed is the non-reagent neutralization of liquid and solid fractions of organic waste in a plant with minimal dimensions, at low energy and material resources with a maximum degree of neutralization and maximum productivity.

The problem is solved due to the fact that in the device for the non-reagent neutralization of waste containing a loading unit for infected objects, feeding and grinding units, a reactor, a press, a receiving tank, a two-way mixer valve is installed at the inlet of the reactor, and at its outlet there is a valve that, Together with pumps and sensors installed in the grinding unit, reactor, press and supply tank, as well as a control system, they provide the necessary reactor operation mode depending on the morphology of the volumes to be neutralized Comrade - continuous or jog.

Figure 1 shows the structural diagram of a device for reagent-free waste disposal.

The reagentless waste neutralization device contains a loading unit 1, into which organic waste intended for neutralization is placed, a feeding unit 2 in the form of a screw conveyor, with which neutralized waste is fed to the grinding unit 3, reactor 5, the action of which is based on the acoustic cavitation method, in which neutralized waste in a liquid medium is subjected to intense ultrasonic irradiation, in which a relatively low energy density of sounds is transformed the first field in the high energy density of the microbubble arising from cavitation, which leads to the destruction of microbial cells - liquefaction of protoplasm, increasing their size and rupture the cell membranes. The liquid-dispersed mixture thus rendered harmless in the reactor is fed to a press 7, where it is separated into liquid and solid fractions. The solid fraction enters the receiving tank 15, and the liquid fraction is returned by the pump 8 to the supply tank 9 for reuse.

To solve this problem, the following are additionally introduced into the device for reagentless waste neutralization: a two-way valve mixer 4, in which the waste ground in the grinding unit 3 is mixed in a certain proportion before disinfection with water coming from the feed tank 9 through the pump 10, providing a water-dispersed mixture of neutralized waste ; a control unit 16 with a control bus and an information bus associated with the level sensor of the crushed waste 11 located in the grinding unit 3, the liquid level sensor 12 in the reactor 5, the level sensor of the neutralized waste 13 located in the press 7 and the water level sensor 14 located in supply tank 9, as well as a controlled valve 6, installed between the outlet of the reactor 5 and the inlet of the press 7, connected through a pump 8 with a supply tank 9. Moreover, a controlled two-way valve-mixer 4 is connected between the output of the controlled block grinder 3 and the input of the controlled reactor 5. One input of the two-way valve-mixer 4 is connected to the output of the grinder 3, and the second to the output of the controlled pump 10, the input of which is connected to the supply tank 9. Thus, the crushed waste at the inlet to the reactor 5 is in a certain proportion mixed with water and completely fill it, which is controlled by a liquid level sensor 12.

Between the exit of the reactor 5 and the input of the controlled press 7, a controlled valve 6 is installed, which is used to regulate the filling of the reactor chamber 5 with disinfectable waste and the discharge of the disinfected waste after its processing into the press 7, in which they are separated into liquid and solid fractions. The solid fraction of the disinfected waste from the press 7 enters the receiving tank 15, and the liquid fraction is pumped by a controlled pump 8 for recycling into the feed tank 9.

Automatic control of the waste disinfection process is carried out through the control bus connected to one of the inputs of the control unit 16, the second input of which is connected through the information bus and corresponding sensors to the grinding unit 3 (sensor 11, which provides an indication of the level of ground waste in the grinding unit 3), reactor 5 (sensor 12, which provides an indication of the level of liquid dispersed mixture in the reactor 5), a press 7 (sensor 13, which provides an indication of the level of disinfected waste in the press 7), a supply tank 9 (sensor 14, providing an indication of the water level in the supply tank 9).

Above we considered the operation of the device in a continuous mode, when the specific power of ultrasonic radiation is sufficient to create a neutralization mode in the reactor.

Due to the wide morphology of objects to be neutralized, a start-stop mode is provided in the device. At the same time, the waste to be treated is subjected to ultrasonic irradiation for a predetermined time, which provides a reagent-free waste disposal with a specific morphology.
