Description

The invention relates to methods and devices for ensuring fire safety of objects characterized by high dust content, the presence of debris and dirt, such as garbage and mass pipes, tunnels, cable channels, and can be used to automatically detect fire danger and extinguish, as well as to automatically maintain good working condition (clean) of the means and objects used for these purposes.

It is known that garbage chutes, mass pipelines, technological channels and tunnels accumulate a lot of fat deposits, dust and dirt during operation, which complicates their operation and creates a fire hazardous situation at such facilities. Existing methods, systems and devices address the problems of pollution and fire hazard of such objects, as a rule, separately and independently from each other.

A known fire extinguishing system in the trunk of the chute (paragraph RF 226875), containing a device that automatically provides extinguishing fluid to the trunk of the chute when a fire occurs and automatically shuts it off when a fire is localized, equipped with a device located in the chute of the chute, made in the form of a pipe with cutouts that provide garbage flow through the chute valves, with the possibility of overlapping chute valves when a fire occurs in the chute trunk.

A known fire extinguishing system in the trunk of a garbage chute manufactured by JSC "Prana" ( www.ao-prana.ru ), containing a device located at the top of the garbage chute, automatically supplying fluid to the chute chute and automatically shutting it off when a fire is localized, a fire extinguishing system sensor, including automatic water supply, as well as automation for closing the gate in the lower part of the garbage chute when ignited in the garbage collection chamber and for extinguishing in this chamber.

It is also known a device according to p. RF No. 2198274, in which, when a fire ignites, a low-melting lock is melted connecting the two parts of the gate, thereby relieving the torque forces of the springs, after which an additional fire damper takes up a position that locks the chute and prevents the spread of smoke through the chute through the floors of the building . The fire in the garbage chute in this case is eliminated by the fire system provided for in the project, if any, or in another way.

To ensure a good working condition (cleanliness) of objects characterized by dustiness, the presence of debris and dirt, various cleaning organs, brushes, etc. moving along the barrel are used. (p. RF 2168595, 2170313).

As can be seen from the above examples, the processes of ensuring serviceability (cleanliness) and ensuring fire safety are carried out separately and independently from each other, and therefore it was not possible to identify the closest analogue from the prior art.

The objective of the technical solution is to develop a method and device for detecting fire danger, extinguishing and ensuring the serviceability (cleanliness) of the means used for these purposes, as well as the objects themselves, in conditions of high dust, the presence of debris and dirt in the protected object.

The technical result of the method and device is to increase the ease of use of objects by reducing the complexity of the process of extinguishing them and ensuring the health (purity) of both the objects themselves and the means used for these purposes, as well as reducing material consumption by performing fire detection and extinguishing functions by common means and maintenance (cleanliness).

The proposed method and automatic station allow you to automate at low cost processes:

- monitoring the fire hazard of the protected facility;

- maintaining in good condition (clean) the means used for monitoring and extinguishing, as well as the facilities themselves;

- supply and transportation to the source of fire extinguishing agent;

- supply and transportation of a washing and / or disinfecting solution.

The problem is solved by the fact that a method for detecting fire hazard and extinguishing an object, as well as automatically ensuring the serviceability (cleanliness) of the means used for these purposes and the object itself is proposed, which consists in the fact that the gas-air mixture is aspirated from the object through an aspiration-feeding pipeline and its simultaneous monitoring for the fire hazard of the facility and separately for contamination of the suction and supply pipe, then the received information is transmitted to the control device and forms ruyut power control commands to aspirate or quenching or washing and / or disinfection, followed by continued aspiration and transported or fed by feed pipe fire extinguishing agent or cleaning and / or sanitizing solution. The control of the gas-air mixture for fire hazard is carried out by measuring the temperature or the rate of rise of temperature, or the gas composition, or the optical density of the samples of the gas-air mixture. The air-gas mixture is checked for contamination of the suction-supply pipeline by measuring the pressure at its inlets and outlets or by measuring the speed of pumping samples of the gas-air mixture through the suction-supply pipeline.

The problem is also solved by the fact that a control station is proposed comprising a control device that is electrically connected to an aspiration device, a blocking unit and an electrically launched deluge unit, the blocking unit being mechanically connected to an electrically launched deluge unit, an aspiration device and an aspiration-feeding pipeline and has an input for washing and / or disinfecting solution and exit to the drain.

The suction device, which is part of the control station, contains a housing having an inlet and an outlet, between which fire detectors and a filter are placed, and an pollution control device is installed at the input, and a fan is installed at the output. The pollution control device is made in the form of an air flow velocity sensor or in the form of pressure sensors located at the inlet and outlet of the suction-supply pipeline. The aspiration device contains two or more fire detectors connected at the output according to the AND circuit, or contains two or more fire detectors connected at the output according to the OR circuit. Fire detectors are made of thermal differential, and / or thermal maximum differential, and / or optical smoke, and / or smoke ionization, and / or gas, or combined.

The proposed technical solution differs significantly from the known analogues in that it has a control station and a multifunctional suction and feed pipe that performs the functions of: a fire feed pipe, a channel for an aspiration system for early fire detection, a pipe for supplying a washing and / or disinfectant solution, so it is possible to implement such a wide method that allows to detect and extinguish a fire, as well as, in the absence of fire factors, wash and / or disinfect CT and suction and supply pipe. The prior art similar methods and devices are not known, which indicates the novelty and inventive step.

The proposed technical solutions are illustrated by drawings, which depict:

figure 1 is a block diagram of an automatic station;

figure 2 - suction device;

figure 3 is an example of a specific implementation of the method using an automatic station.

The control station 1, shown in figure 1, contains a standard electric launcher deluge unit 2 with a supply pipe OTV, electrically connected to the control device 3, which, in addition, is electrically connected to the suction device 4 and the blocking unit 5. The blocking unit 5 is a pneumatic-hydraulic distributor with electromagnetic drives, having inputs A, B, C, D, E, while input A is mechanically connected to the drainage system; input B - with electric trigger deluge unit 2; input C - with an aspiration device 4; input D - with a tank of washing solution (not shown); entrance E - with suction and supply pipe 14.

The aspiration device 4, shown in FIG. 2, has a housing 6 with an input 7 and an output 8, between which fire detectors 9 and a filter 10 are placed, and a pollution control device 11 (air flow sensor or pressure sensor) is installed at the input 7, and at the output 8, a fan 12 is installed.

Figure 3 shows a specific example of a method for detecting fire hazard, extinguishing and cleaning the chute using the invented station. The figure depicts a control station 1 with a tank 13 of cleaning solution and an exhaust suction pipe 14 extending from it, having distributed, for example, floor pipes 15 with nozzles 16 placed obliquely inside the loading valves 17 and in the waste chamber 18 of the barrel 19 of the garbage chute.

The control station provides automatic modes: standby, fire fighting and washing and / or disinfection of the chute.

The operation of the control station is as follows.

Constantly aspirate the air-gas mixture from the barrel 19 through nozzles 15 with nozzles 16 and the suction-supply pipe 14 connected through the inputs C and E of the locking device 5 to the suction device 4, the fan 12 of which creates a suction effect and “draws” the gas-air mixture through the inlet 7 through the pollution control device 11, through the filter 10, through fire detectors 9 to the exit 8, while the pollution control device 11 or fire detectors 9 in the event of fire or contamination of the hearth m electric signal to the control unit 3.

In the absence of fire or pollution factors (standby mode), the control device 3 generates a corresponding control signal to the blocking unit 5, which is activated and opens the input C, if it was blocked, or leaves it open, thereby connecting the input 7 of the suction device 4 to the input E, to which the suction and supply pipe 14 is connected, while the inputs A, B, D are blocked. This mode is maintained until the occurrence of fire or pollution factors.

In case of fire factors (particles of smoke in the air, increased air temperature or its rise rate, the presence of gas, for example, СО), the control device 3 receives a signal from fire detectors 9 and, in turn, generates control signals to the electric launch deluge unit 2 and blocking unit 5, whereby blocking unit 5 blocks the input C connected to the suction device 4 and opens the input B, through which the deluge unit 2 is connected to the input E, to which the suction-supply pipe 14 is connected, p and this deluge unit 2, receiving the control signal from the unit 3 on the operation, takes the extinguishing agent into the barrel 19 through the tubes 15 with nozzles 16. Inputs A and D 5 in the lock mode extinguishing device closed.

If pollution factors arise (washing and / or disinfection mode), the control device 3 receives a signal from the pollution control device 11, namely, a pressure sensor or an air flow rate sensor, after which the control device 3 generates a control signal to the blocking unit 5, which blocks all previously opened entrances and opens the entrance D, connecting with the input E, to which the suction and supply pipe 14 is connected, while washing and / or disinfecting solution enters, which is transported through the pipe 14 ruetsya further into the barrel 19 through the tubes 15 with nozzles 16. The inputs A and C are locking devices 5 are closed in this mode.

To implement the invention, it is proposed to use a standard deluge unit with an electric drive that meets the requirements of GOST R 51052-02, as well as a well-known device, for example ППКОП 019-1-15 "Picket 2", and the known pneumohydrodistributor with an electromagnetic drive is used as a blocking unit. The suction unit uses commercially available detectors, sensors, a filter and a fan.

The proposed method and device significantly reduce the complexity of the extinguishing processes and ensure serviceability (cleanliness) of both the objects themselves and the means used for these purposes, as well as reduce material consumption by performing the general means of fire hazard detection, extinguishing and maintenance (cleanliness).
