Description

The invention relates to medicine, and more particularly to the field of collection of health care waste in intermediate storage containers for their disposal in vehicles to the place of thermal neutralization by burning in furnaces with a vertical combustion chamber.

The level of this technical field characterizes the method of collection, storage and disposal of waste from medical institutions, which are subject to mandatory thermal neutralization, prescribed by the "Sanitary Rules and Norms" SanPiN 2.1.7.728-99.

The wastes of medical institutions are all types of wastes generated in: hospitals (citywide, clinical, specialized, departmental, as part of a research, educational institution); clinics (including adults, children, dental); dispensaries; ambulance stations; blood transfusion stations; long-term care facilities; medical research institutes and educational institutions; veterinary hospitals; pharmacies; pharmaceutical industries; health facilities (sanatoriums, dispensaries, rest homes, boarding houses); sanitary facilities; forensic medical institutions; medical laboratories (including anatomical, pathological, biochemical, microbiological, physiological); private health care enterprises.

All health care waste is divided according to the degree of epidemiological, toxicological and radiation hazard into five classes, three of which are subject to thermal disposal:

class A - non-hazardous wastes of healthcare facilities: not in contact with body fluids of patients infected with patients, non-toxic; food waste of all divisions of medical facilities except infectious (including skin and venereologic), phthisiatric; furniture, inventory, faulty diagnostic equipment that does not contain toxic elements; uninfected paper, estimates, construction waste, etc .;

class B - hazardous (risky) wastes of healthcare facilities: potentially infected materials and instruments contaminated with patient discharges, including blood, patient discharges; pathological wastes; organic operating waste (organs, tissues, etc.); all waste from infectious diseases departments (including food), from microbiological laboratories working with microorganisms of 3-4 pathogenicity groups; biological waste of vivariums;

Class B - extremely hazardous wastes of healthcare facilities: materials in contact with patients with especially dangerous infections; waste from laboratories working with microorganisms of 1-2 groups of pathogenicity; Wastes from TB, microrological hospitals; waste from patients with anaerobic infection.

The technology for the collection, temporary storage and transportation of waste medical facilities contains the following operations:

- waste collection within the medical unit;

- transportation and transshipment of waste in (inter) container containers;

- temporary storage of waste in the territory of the health care facility;

- transportation of (inter-) case containers to the place of thermal waste neutralization.

Moreover, the mixing of waste of various classes at all stages of their collection, storage and transportation is unacceptable.

Class A wastes are generated in the following structural divisions of medical facilities:

- Ward waste of departments (except for infectious, dermatovenerologic, phthisiatric, microrological);

- administrative premises;

- central catering units, cupboards of departments (except for infectious, dermatovenerological, phthisiatric, micrological);

- off-campus territory.

Class A waste is collected in reusable bins or disposable white plastic bags that are fixed on trolley racks (Fig. 1) or inside reusable bins.

Healthcare waste classes B and C are pre-disinfected by immersion in a disinfecting solution of a given concentration for the exposure time determined by the relevant recommendations.

The bags are fixed on trolley racks or placed in disposable solid packaging with a capacity of 11 l, distinguishable in shape and color for waste of different classes: white for class A (figure 2), yellow for class B (figure 3), red for class B (figure 4).

Disposable solid packaging is closed with a sealed lid with a control seal.

Neck package made of polyethylene film of thickness 0.03-0.05 mm minimum capacity of 50 liters (1000 × 600 mm) after filling waste at _^3/4 volume collected into a bundle, which delay the mechanical coupler. Before forming the bundle of the neck of the package, air is squeezed out of it.

Waste not intended for collection in packages according to class B: needles, metal tools (pricking, cutting) and class C: organic and microbiological waste is collected in disposable solid packaging, hermetically sealed with a lid.

Class A waste can be collected in reusable containers, which are washed daily with a disinfectant solution.

Trolley racks are equipped with wheels and handles on the opposite side.

Class B waste sites:

- operating;

- resuscitation;

- procedural dressings and other manipulative and diagnostic rooms of medical facilities;

- Infectious, skin and venereologic departments of hospitals;

- medical and pathological laboratories;

- laboratories working with microorganisms of 3-4 pathogenicity groups;

- vivariums, veterinary hospitals.

All waste generated in these units is disinfected by immersion in a disinfectant solution prepared in a container specially allocated for this purpose within the unit, at a given concentration and for the recommended exposure time.

After disinfection, class B wastes are collected in yellow plastic bags attached to trolley racks.

Organic waste generated in operating rooms, laboratories, microbiological waste is collected in disposable sealed solid packaging.

Sharp instruments (needles, feathers) that have been disinfected are collected separately in a disposable, solid package.

Class B waste sites:

- units for patients with especially dangerous and quarantine infections;

- laboratories working with microorganisms of 1-2 groups of pathogenicity;

- Phthisiatric and mycological clinics (departments).

Class B wastes are collected in red plastic bags mounted on trolley racks.

Microbiological cultures and strains, vaccines are collected in a single, sealed, solid packaging.

After filling and sealing disposable bags and solid packages, they are labeled with the unit code of the health facility, the name of the institution, the date and name of the person responsible for the collection of waste.

Covered waste in bags and disposable solid packaging on trolley racks is separately transported by class to places of temporary storage in inter-container containers with a capacity of 120 l (figure 5): classes A and B - in open areas, and class B - only in an isolated room of the unit .

Inter-container containers are marked and equipped with an airtight, watertight lid with a lock and wheels for ease of loading into a closed box of a special vehicle.

Temporary storage areas are located at a distance of at least 25 m from the buildings and at least 100 m from the catering units.

The sites are covered with asphalt and have drains.

Class B internal storage rooms have ceramic tile floors, glazed tiles to the full height, and a ceiling covered with moisture-resistant paint.

The room is equipped with a washbasin, watering tap, water drain, bactericidal irradiator, ventilation.

Disposable hermetically sealed bags and solid packages are transported from temporary storage and waste accumulation places inside medical facilities to inter-housing areas for reloading into inter-housing containers on manoeuvrable trolley racks, the metal structure of which ensures its stability in a stationary position, has wheels and handles for convenient and safe displacement.

Class A, B, C waste is removed daily.

Transportation of containers with healthcare waste to the place of thermal disposal is carried out in closed bodies of special vehicles, which ensure the safety of the cargo and the safety of transportation.

The placement and securing of goods in vehicles is carried out taking into account the requirements of traffic safety, cargo safety and vehicle. When loading, the cargo is securely fixed, preventing its movement.

When loading inter-container containers into the closed body of a special vehicle in their place, a removable empty inter-container container is installed at the storage site, the disinfection of which is carried out at the place of thermal neutralization of waste by the exporting organization.

In special vehicles, healthcare waste is transported in inter-container containers and / or in disposable 11-liter solid packages, which are placed in trays fixed in a closed box.

Vehicles used for the transport of healthcare waste carry the “Biohazard” hazard label

Class B and C wastes must be subjected to mandatory thermal neutralization, and Class A wastes can be subjected to thermal neutralization or taken to special landfills (clause 9.3 SanPiN 2.1.7.728-99).

The disadvantages of this method are as follows.

The mechanical screed of the neck of the polymer bags does not ensure the tightness of the corking of hazardous waste, which leads to the fact that the environment is polluted around the inter-storage storage area and in the back of the vehicle, therefore, along the entire transportation route to the place of thermal neutralization, which is unacceptable.

At the same time, infected air from the bag for capping operations to form a neckline is forced out of the bag into the atmosphere of the treatment room, infecting it.

Waste collection at the place of generation into containers of various types and colors, which must be separately loaded into inter-container containers, stored and thermally neutralized, complicates the process and does not exclude mixing, which requires mandatory reclassification of waste to an increase in hazard class that is not controlled, therefore, given the human factor, is optional.

Storage of healthcare waste requires a separate, specially equipped room inside the healthcare facility.

The removal of healthcare waste in containers and / or disposable solid packaging requires additional equipment of the car body with supporting means and various fastening devices, which complicates and increases the cost of work.

Subjective control over the transport transporting healthcare waste is ineffective, since it is based on data from unreliable sources: drivers, persons responsible by law for the timely removal and disposal of hazardous waste, controllers, etc., who for one reason or another hide or falsify information.

Special vehicles do not have refrigeration equipment to create a low temperature in a closed body, which prevents the development of a pathogenic environment.

If there is no means of continuous biocidal treatment of the volume in a closed body, daily wet disinfection is required.

In well-known furnaces for burning healthcare waste, fuel (gas, fuel oil) is additionally consumed, which makes the process more expensive, and the absence of an exhaust gas purification system, by definition, causes harmful and toxic emissions into the atmosphere.

The problem to which the present invention is directed is the creation of a unified system for the separate collection and tightly corking of healthcare waste in a unified container, their temporary storage and transportation in modified special vehicles to places of localized burning without harmful emissions, with constant monitoring of loading / unloading and transportation by means of satellite navigation system, with automatic documentation in electronic information carriers.

The required technical result is achieved by the fact that in the known method for the disposal of healthcare waste, which contains separate collection at the places of waste generation of classes A, B, C in a closed storage container, which is placed in carts to be transported to a closed body of a special machine transporting waste to the place their thermal neutralization, according to the invention, the collection, storage and transportation of health care waste is carried out in disposable solid box-shaped packaging made of laminated cardboard with a thermoplastic polymer coating and equipped with an identification barcode, the open end of which, after filling with waste, is folded along the grooves, forming a geometric closure cover, while the top joint of the cover is hermetically sealed by means of an electric heating clamping tool, closed bodies of special vehicles are equipped with an electronic communication unit with a satellite navigation and control system and controls, equipped with a refrigerator and an ultraviolet recirculator, and thermal disinfection of waste Health care products are carried out by autothermal burning in a common vertical two-chamber furnace of layer-by-layer oxidative pyrolysis with air blasting into a separation vault nozzle having automatic loading of sealed packages, an ash removal mechanism, and exhaust gas purification devices.

Distinctive features made it possible to simplify the technology of separate collection of healthcare waste into a unified disposable packaging with a hermetically sealed volume, in which temporary storage and transportation to places of their general localized burning without harmful emissions is carried out with automatic active control of the movements of special vehicles with waste packages, which is recorded on electronic media and archived.

The collection, storage and transportation of the proposed sealed packages with health care waste simplifies the organization and implementation of the listed works systematically, while eliminating the intermediate reloading into negotiable (replaceable) inter-container containers, which are no longer needed.

Hermetically sealed disposable solid packaging allows not to separate health care waste into classes A, B, C during transportation and localized burning in new design furnaces, which is simpler, more productive and cheaper.

The implementation of universal packaging made of laminated cardboard with a thermoplastic polymer coating in the form of a box, equipped with flutes for folding the open end, forming a geometric closure cover, allows hermetic sealing of its upper joint by means of an electric heating clamping tool.

Equipping disposable solid packaging with a barcode allows you to identify the place of waste generation and the exporting organization, which is especially important for unauthorized disposal.

Equipping closed bodies of special vehicles for transporting universal sealed packages with waste with an electronic communication unit with a satellite navigation, monitoring and control system allows you to determine their location in real time, record all technological operations on electronic media from loading packages with waste to feeding them to the incinerator, stopping and deviations from the route.

The installation in closed bodies of special vehicles of the refrigeration system ensures the storage of waste during transportation at an optimum temperature of 5 ° C, regardless of the ambient temperature.

The installation in the bodies of special vehicles of an ultraviolet recirculator provides forced ventilation of the enclosed volume with air, which undergoes constant bactericidal treatment, thereby preventing uncontrolled pollution of the atmosphere.

Thermal neutralization of healthcare waste by autothermal burning of layer-by-layer oxidative pyrolysis in vertical two-chamber furnaces with air blasting into the separation vault nozzle ensures complete oxidation of the combustion products almost to the final products of chemical reactions, which is environmentally friendly and safe.

Automatic feeding of sealed packages of waste directly into the insulated volume of the furnace allows you to synchronize the speed of portion loading and burning of waste, which does not need to be divided into classes, which simplifies the work.

The ash removal mechanism, fulfilling its intended purpose, during waste incineration, ensures in the process a predetermined free volume of the armrest space, which is necessary to stabilize the gas dynamics of autothermal combustion.

The autothermal combustion mode minimizes the energy consumption of the fuel, which is necessary only for firing up the furnace and reaching its temperature mode.

In the structure of the healthcare waste incinerator, there are exhaust gas purification devices (in particular, a scrubber, a two-cascade continuous cascade filter) that trap dust residues before the gas stream is released into the atmosphere.

Consequently, each essential feature is necessary, and their combination in a stable relationship is sufficient to achieve the novelty of a quality that is not inherent in signs of disunity, that is, the technical problem is solved not by the sum of the effects, but by a new super-effect of the sum of the attributes.

The invention is illustrated by an example of organization of a system for the treatment of medical and biological waste, which includes the following steps:

- collection and accumulation of waste in a unified closure, sealing and labeling of closures, temporary storage on the premises of the department;

- transportation of airtight corking to the place of laying in the inter-vehicle trolley;

- transportation of the inter-vehicle trolley with hermetic closures to the loading point in the closed body of the special vehicle;

- transshipment of tight closures from interbody carts to the closed body of a special vehicle;

- waste removal from the territory of the health care facility;

- transportation of waste to the places of their disposal and satellite control over their movement;

- Utilization of hazardous biomedical wastes by burning in an autothermal oxidative pyrolysis mode.

The following example of the proposed method is purely illustrative and does not limit the scope of the claims of the totality of the essential features of the formula.

A distinctive feature of the proposed method is that health care waste of various classes A, B and C are separately collected in a single unified solid packaging (Fig.6), which is sealed after filling.

Storage and transportation of hermetically sealed waste of different classes excludes their mixing, and co-burning is carried out in an isolated volume of the furnace to the final oxidation products.

The proposed unified packaging with a capacity of 16 liters in the form of a box is made of laminated cardboard coated with a thermoplastic polymer film that carries a label with a barcode that includes information about the medical institution, date of use and exporting organization.

The open end of the box has flutes 1, along which its faces are folded in pairs, forming a double cover 2 of geometric closure, the joint 3 of which, after filling with waste, is welded in a clamping electrically heated device (not shown conditionally) with a continuous longitudinal seam, which ensures reliable mechanical fastening and tightness of the package.

Boxes for the collection of medical waste are installed in health care facilities at the place of their formation, where they are separately filled with waste of classes A, B and B.

Sealed boxes in the amount of 18 pcs are placed in the inter-sectional trolley (Fig. 7), in which they are stored and transported to the place of loading in the closed body of a special vehicle equipped with trellised trays-pallets for stable placement of sections with packages of inter-frame trolleys on them.

On vehicles for waste collection in sealed packages, on-board electronic units connected to the control sensors mounted on the systems and units of the special vehicle are connected through a GSM antenna and GPS antenna with a satellite navigation system.

Each on-board electronic unit is loaded with information about the designated route of movement and a program of reaction to emerging events. Information is processed by the on-board unit computer, providing vehicle control regardless of communication with the server of the central observation point.

A multifunctional satellite navigation system allows real-time monitoring of the location of vehicles that transport hazardous waste, the state of its key components and assemblies, responding to specified events, issuing commands and sending messages using the built-in modem.

By defined events, in particular, it is understood that a certain route address has been reached, the fact of loading / unloading containers with waste, automatic recording and recording in the database of the real place and time of loading / unloading containers.

In the Center for Waste Transportation Management (TSUTO), incoming reports on all shipments made during the day are systematized, a list of enterprises is formed, indicating the accepted volumes of hazardous waste.

TSUTO determines the route of special vehicles, while the software allows you to record and reproduce information about the movements and parking of special vehicles for any period of time.

Using a graphical editor, the TsUTO dispatcher can create a route and assign it to a vehicle, also set the response of the airborne unit to a given sequence of events for different sections of the route, automatically record and record any fact of deviation from the given route in the database.

TSUTO submits a report to the executive bodies and enterprises operating in this field, records all cases of violations of the established schedule for the movement of waste, sends information about deviations from the approved routes.

Information is reflected and recorded in real time on electronic cards, on displays. All events are automatically documented in the TSUTO database, archived and used for daily analysis.

Thermal neutralization through localized burning of pathological, anatomical and infected medical waste is practically the only effective way.

Health care waste is burned in a vertical two-chamber furnace (Fig. 8.1), containing a lined combustion chamber 4 and an afterburner 5.

The combustion chamber 4 and the afterburner 5 are interconnected by a central nozzle 6 of the intermediate arch.

The furnace is equipped with a system 7 for supplying oxidizing air in an equal volume to the tubular grate 8 and to the channels 9 of the nozzle 6.

The distributed channels 9 of the nozzle 6 are arranged in two rows in height and are inclined at an angle of 30 ° to the longitudinal axis and directed into the afterburner 5.

The outlet 10 of the tubular grate 8 is located on its bottom surface.

In the grate 8 mounted lining 11, made in the form of cranks mounted on the shaft 12 of the drive of their rotation (not shown conditionally).

Above the bottom of the combustion chamber 4 there is a scraper 13 mounted on the rod of the hydraulic cylinder 14 of its transverse movement.

Below are placed the trays 15 ash removal, in which the screws 16 are installed.

The combustion chamber 4 is provided with a pipe 17 for supplying material to the loading window 18.

On the outlet pipe 19 of the afterburning chamber 5, a cover 20 is pivotally fixed, which is connected via a lever 21 to a manual drive.

The feed pipe 14 of the furnace is combined with a feed screw 22 mounted under the rotary chopper 23 of materials in the boxes coming from the hopper 24 connected to the exhaust fan 25.

Between the grinder 23 and the screw 22 there is a nozzle 26 spraying liquid materials (10-15 wt.%) To be burned, if necessary.

A flue gas duct 27 connected perpendicularly to the axis of the afterburning chamber 5 connects it to a scrubber 28 (Fig. 8.2), the central nozzle 29 of which communicates by means of a pump 30 with a water tank 31 installed on the outlet pipe 32 communicating with the pipeline 33.

The pipeline 33, equipped with a discharge fan 34, communicates via two autonomous streams 35 (Fig. 8.3) through the slide valves 36 with parallel exhaust aerosol filtering devices 37, each of which is a cascade of interchangeable cartridges 38 made of fibrous filter material, in particular basalt fiber.

The outlet of the streams 35, blocked by the slide gate valves 36, is connected to the chimney 39 through an exhaust fan 40.

The described flow of healthcare waste incineration operates as follows.

To ignite the furnace (with the open cover 20 on the pipe 19), the furnace chamber loading of the chamber 4 is used for burning with wood, wood shavings, wood chips, etc., the combustion of which provides a temperature rise to the level of 1200-1400 ° C.

The gases of the ignition mode are released out through the open pipe 19 of the furnace.

After that, with the lid 20 closed, the combustion chamber 4 is loaded with solid fragmented medical waste by means of a screw feeder 22, which is pushed through the pipe 17 and through the window 18 to the grate 8, respectively, in portions and continuously dosed.

Packages of medical solid waste (used bandages, cotton wool, disposable syringes, needles, ampoules, vials, blood transfusion systems, rubber tubes, gloves, etc.) are individually loaded into the hopper 24, from where they gravitationally enter the grinder 23, where they are fragmented to the established sizes.

The fragmented solid material is further mixed with liquid dispersed from the nozzle 26, which adheres to the entire surface of the pieces (50-200 mm) falling into the screw feeder 22.

By a screw feeder 22, the fragmented material is compacted and fed into the loading pipe 17 of the combustion chamber 4.

The dense mass of the feed material formed in the pipe 17 has a high aerodynamic drag and acts as a gas valve, which allows continuous loading of the furnace, comparable in weight to the flow of combustible material in the combustion chamber 4 placed on the grate 8.

The air removed by the exhaust fan 25 with vapors from the hopper 24 is supplied to the system 7 and then to the combustion furnace.

From the inclined channels 9 from the system 7, air is blown at a speed of 28 m / s, which creates an insulating curtain of the working volume of the combustion chamber 4.

From the pipe 17, the material is pushed onto the grate 8, where it is burned.

At the same time, oxidizing air is supplied under the grate 8 from the holes 10 at a speed of 18 m / s, which is distributed into the volume of discrete material burned, increasing the combustion area and activating the process with a temperature increase to 1050-1150 ° C.

The geometry of the nozzle 6, the number of channels 9 at two levels of their location, the slope of the channels 9 to the longitudinal axis of the furnace, providing optimal thermal and gas-dynamic modes, were calculated using the mathematical model of the design of the experiment.

It was experimentally established that the products of oxidative pyrolysis are retained in the combustion chamber 4 for at least 2 s, which is sufficient for the oxidation of soot, as the most inert and difficult to burn component of any layered combustion.

The jets of oxidizing air supplied at a speed of 35 m / s from the air duct of the system 7 are directed along inclined channels 9 to the afterburning chamber 5 and suction the gaseous products from the combustion chamber 4, which are transferred to the afterburning chamber 5. At the same time, in the nozzle 6 there is an active mixing of the gaseous products of combustion with oxidizing air coming from the channels 9, forming an aerosol.

In the afterburning chamber 5, the gas-air mixture expands, losing speed, and is burned to the final products at a temperature of 1250-1300 ° C, as evidenced by the almost complete absence of soot in the duct 27.

The presence of controlled oxygen at a rate of 15-17 m / s in controlled aerosol of at least 3 wt.% Guaranteed confirms its excess in the furnace for oxidative pyrolysis, which ensures complete combustion of various solid and liquid materials in an autothermal mode, without the use of additional fuel.

Periodically (after 30 minutes), the crankshaft turning drive 8 is turned on, which tear the combustible material on the grate 8, preventing the formation of arches, and destroy the sintered crust, which activates combustion by increasing the contact area with oxidizing air.

A scraper 13 from the bottom of the ash burning chamber 4 and slag collide into the trays 15, where the screws 16 are automatically brought out.

In the gas duct 27, an aerosol stream with a temperature of 1100-1200 ° C unfolds and brakes while entering the scrubber 28, where the aerosol temperature sharply decreases due to evaporative cooling by the dispersible nozzle 29 of water to a level of 250-300 ° C (the so-called “quenching” occurs "Aerosol).

The gas-vapor mixture from the scrubber 28 enters through the outlet pipe 32 into the pipe 33, where, by means of a fan 34, which pumps air into the filter device 35, the aerosol is forcedly mixed with atmospheric air while the temperature of the mixture is reduced to 120-140 ° C.

From the pipeline 33, the aerosol through an open stream 35 (with the slide gate valves 36 extended in it) is supplied to the device 37, where there is a cascade of filter cartridges 38 in which solid ash particles are retained on the fibrous gas-permeable material.

Pure gaseous waste products are discharged into the pipe 39 by means of a pump 40 and then enter the atmosphere.

Periodically, in the working stream 35 of the device 37, the gate valves 36 are closed, opening the same gate valves 36 of the second stream 35, thereby connecting the backup filtering device 37 to the operation.

In the disconnected device 37, the cassettes 38 are replaced with clean ones, preparing it for subsequent work. Thus, the change of filter cartridges 38 is carried out without interrupting the technological process of the waste incineration plant.

Prototypes of the described vertical furnaces of various types of structural elements have successfully passed polygon tests for the incineration of solid household, medical and liquid wastes, which allows us to recommend them for serial production when the proposed technological complex organizes separate collection, storage and thermal disposal of healthcare waste with active electronic control all structural operations and transitions.

Universal solid sealed packaging, inter-sectional trolley, special equipment and equipment for automobiles, their bodies, a vertical two-section oxidizing pyrolysis furnace of incinerated healthcare waste are elements of the IMA model range developed and tested in practical use in operations on separate collection of healthcare waste at their place education, hermetic corking, temporary storage, joint transportation and safe localized burning.

A comparative analysis of the proposed technical solution with identified analogues of the prior art, from which the invention does not explicitly follow for a specialist in the disposal of harmful and toxic healthcare waste, showed that it is not known, but taking into account the possibility of practical implementation of the method of separate collection, storage and thermal neutralization medical waste classes A, B and C, we can conclude that it meets the criteria of patentability.
