J & Schff für disinfection of the trunk of garbage chutes of residential and public buildings

The invention relates to the utilities sector and is intended for disinfection of the barrel of typical refuse chutes of residential and public buildings of a traditional design without their structural refinement.

To improve the sanitary condition of garbage chutes, both mechanical and chemical methods, as well as their combination, can be used.

Mechanical methods include cleaning and flushing the inside of the chute. Mechanical methods are expensive because it requires the creation and installation of new waste chutes; s with a stationary cleaning and flushing system or the structural refinement of existing waste chutes, which is also expensive and not always possible.

Chemical methods consist in treating the inner surfaces of the garbage chute with disinfectant solutions or formulations in order to suppress pathogens. This task is the main one, since the presence of an ascending air flow due to ventilation in the trunk of a garbage chute can lead to air poisoning in entrances and other rooms of residential and public buildings equipped with garbage chutes.

Known waste chute of a multi-storey building, including a barrel, a cleaning body moving along the barrel and connected by a cable to a device for lifting it, located higher than the last loading valve of the barrel of the chute on the floor or under the overlap of a technical or last floor (RF patent No. 2168595, class E 04 F 17/10, B 08 B 9/02, 2001). To flush the waste chute, water can be supplied to the top of the barrel, into which a disinfectant solution can be added. The water supply system and its mixing with a disinfectant solution is stationary and is placed in a separate cabinet. Barrel disinfection is carried out by washing with water with the addition of a disinfectant solution. The fluid flows to the top of the barrel and flows down the chute.

This solution is intended for use in the construction of new buildings or the reconstruction of old buildings.

A partially mobile device for washing a barrel of garbage chutes is known, which contains a housing with a drum and a cable placed in it, a working body for cleaning the barrel with a load, and a barrel washing system in the form of a shower, into which the disinfectant solution is added (RF patent No. 2194829, class E 04 F 17/10, 2000). A device for washing the barrel of the garbage chute is stationary installed in its upper part and is made in the form of a shower. The water supply system is connected to the internal water supply of the building. The disinfection system is combined with the washing system of the trunk of the garbage chute. The movable element is the working body for cleaning the trunk of the garbage chute, made in the form of a brush-ruff with a load, which is suspended on a cable and can be lowered and raised when the drum rotates.

The patent describes the operation of the device, which complements the description of its design and discloses a method for disinfection of the chute. The barrel is disinfected by rinsing with water and disinfectant. The fluid is supplied to the upper part of the barrel through the blower in the form of an annular perforated pipe and flows down the inner surface of the barrel of the garbage chute. At the same time, the trunk of the garbage chute is cleaned by lowering and raising the brush. Thus, the disinfection of the chute is carried out by washing

a disinfectant solution supplied to the top of the chute, which is complemented by a cleaning process using a brush-ruff moving along the height of the barrel.

Removable and portable structural elements are a drum with a cable and an external shaft with a handle related to the mechanism of cleaning the trunk of the garbage chute. This device is intended for the acquisition of new or reconstructed buildings, that is, it is not fully portable and cannot be used without the completion of typical garbage chutes, which is associated with significant costs, including maintenance and repair. In addition, disinfection of the garbage chute by washing it will lead to a large consumption of disinfectants, which can lead to an environmental problem, especially in a large city.

The closest analogue is a device for cleaning vertical pipes (French patent No. 2256637, class B 08 B 9/02, 1975), which is intended primarily for cleaning, washing and disinfecting trunks of garbage chutes. This device is permanently installed on the bed in the attic of the building and consists of a cleaning device in the form of a metal cargo cylinder with brushes, mounted on a flexible hose, an electric drum for lowering and lifting the cleaning device and a tank with a pump for supplying disinfectant liquid.

The patent contains a description of the operation of this device, which discloses a method for disinfection of the trunk of the garbage chute. Disinfection of the trunk of the garbage chute is carried out in the process of washing and cleaning with a cleaning device that is lowered into it on a flexible hose. The cleaning device is lowered and raised using an electric motor rotating the drum with a flexible hose wound around it. The tap water supplied for washing is mixed with a disinfecting liquid, through a flexible hose it enters the cleaning device and is poured onto the inner surface of the garbage chute barrel. In the process of cleaning and washing, dirt and water flow into the garbage collection chamber, in which the control panel for the operation of the garbage chute cleaning device is located. The trunk of the garbage chute is equipped with control devices for the movement of the cleaning device.

This device can be used to complete new or reconstructed buildings. It is not applicable without constructive refinement of typical garbage chutes of operated buildings. In addition, disinfection combined with washing the garbage chute will lead to an increased consumption of disinfectants, which can lead to an environmental problem.

The task of the invention is to enable simple and cheap disinfection of typical garbage chutes of a traditional design, which do not provide any built-in technical devices for their disinfection, washing and cleaning, that is, without finalizing typical garbage chutes.

The technical result of the claimed invention is the ability to disinfect the trunk of the chute by irrigating its internal surfaces with a coarse aerosol without cleaning and flushing. The present invention expands the arsenal of means for disinfection of garbage chutes of residential and public buildings. When using the present invention does not require constructive refinement of typical garbage chutes of a traditional design or their replacement.

The essence of the invention is illustrated by a schematic representation of a working device for disinfection of the trunk of the chute, which is presented in the figure together with the scheme of a typical chute. The figure schematically shows the main elements of the device for disinfection of the trunk of the chute: tank for disinfectant solution 1, a flexible hose 2 and a sprayer 3, equipped with spraying elements 4, which during the operation of the device create a torch

atomization 5. The main elements of a typical waste chute are shown: barrel 6, loading valve 7 and waste collection chamber 8 with container 9.

The proposed method for disinfection of refuse chutes of residential and public buildings consists in treating the inner surfaces of the trunk of a garbage chute with a fine aerosol from a spray gun, lowered onto a flexible hose into the garbage chute through a loading valve or revision. The disinfectant solution is fed from a small portable container into a spray hose but flexible hose and sprayed in the trunk of the chute when lowering and (or) raising the spray gun, while irrigating the inner surface of the chute due to the formation of a spray torch. The aerosol disinfection method as applied to rooms, taking into account the effectiveness of processing horizontal and vertical surfaces, has been thoroughly studied and described in the work of P. Lyarsky. and Tsetlin V.M. Aerosol disinfection. M. Medicine, 1981.

The proposed method of disinfection of the barrel of the chute due to uniform irrigation of the inner surfaces of the barrel of the chute when lowering the spray gun on it with a flexible hose allows you to economically use the disinfectant solution, providing the necessary and sufficient density of the irrigation for disinfection, causing moistening of its internal surfaces. In this case, there is practically no pouring of the disinfectant solution into the waste of the waste collection chamber.

The sprayer can be lowered into the chimney barrel for the purpose of processing it from the loading valve of the upper floor to the garbage collection chamber, that is, the entire height of the garbage chute, or from the upper loading valve to the next lower loading valve, while the section of the chute between them is processed. In this case, the chute can be processed by disinfecting all of its sections between the loading valves and from the lower loading valve to the waste collection chamber (container).

The disinfectant solution is supplied to the sprayer via a flexible hose from a portable container due to the creation of excess pressure in it or by means of a pump (pump).

A device for implementing the proposed method consists of a portable container 1, a flexible hose 2 and a sprayer 3, equipped with spraying elements 4. A flexible hose connects the container to the sprayer and allows the sprayer to lower into the waste chute barrel and to supply a disinfectant solution from the tank to the sprayer. For the convenience of work and transportation, a flexible hose can be wound onto a drum or folded into a bay. The sprayer implements the hydraulic principle of spraying and can be equipped with any hydraulic spraying elements - nozzles (centrifugal, screw, fan, slotted, inkjet, shock-jet), which ensure that the internal surfaces of the garbage chute get into the spray torch. Hydraulic spraying elements, when liquid is supplied to them under pressure, provide at the outlet the formation of a liquid film or streams that break up into droplets, forming a coarse aerosol. The process of aerosol formation occurs in a certain volume at the outlet of the spray element, and a spray torch is formed. The use of hydraulic spraying elements is the simplest and cheapest way to obtain coarse aerosol (Pazhi DG, Galustov B.C. Fundamentals of the technique of spraying liquids. M. Chemistry, 1984).

The device is mobile and can be transported and operated by one to two employees.

300 times (compared with the cost of one garbage chute) when performing the main target task - the suppression of pathogenic microflora.

An example implementation of the invention.

Example No. 1.

Disinfection of waste chutes of two residential buildings (twelve and fourteen floors) was carried out using an aqueous solution of the “PVC” disinfectant (certificate of registration. No. 0271-54 / 6 of 06/07/2001). Samples in the form of scrapings from the inner surfaces of garbage chutes were taken before processing and after processing.

Carrying out the treatment led to a decrease in the level of seeding (by the total microbial number) of the inner surfaces of the chutes by 100 ... 1000 times. In addition, as a result of disinfection, microorganisms of the intestinal group, which were detected in samples taken prior to the treatment, were completely destroyed.

Example No. 2.

Disinfection of the waste chute of a fourteen-story residential building was carried out using an aqueous solution of disinfectant “PVC. Samples in the form of scrapings from the inner surfaces of the chute were taken before processing and after processing. Samples from the air (before and after treatment) were taken at the entrance to the garbage chute using a cup-sedimentation method to assess the effect of disinfection of the chute on the level of airborne contamination of the microflora.

The processing has led to a decrease in the {3 level of seeding of the inner surfaces of the chute by 100 ... 1000 times and the level of seeding of air by 10 times. As a result of the treatment, Aspergillus niger fungi were completely suppressed.

Example No. 3.

Disinfection of the waste chute of a ten-story residential building was carried out using an aqueous solution of the Polisept disinfectant (certificate of registration No. 0046-99 / 8 of 03/10/2000). Samples in the form of scrapings from the inner surfaces of the chute were taken before processing and after processing.

The processing has led to a decrease in the level of seeding of the inner surfaces of the chute by about 100 times.

The simplicity and cheapness of the proposed method and device for its implementation will allow you to quickly and efficiently disinfect existing typical garbage chutes of a traditional design using existing disinfection companies and urban disinfection; stations. One set of equipment using the proposed method can process about one hundred waste chutes of a typical design in one month. Unlike all known analogues, this does not require constructive refinement of garbage chutes with the installation of additional equipment and, consequently, its further maintenance and repair.
