Abstract

The equipment has a plotting smoke generator with smoke pots to introduce plotting smoke in a pen of fire. A fire equipment with trays of located combustible fluid on water tanks stabilizes temperature. Screens are provided to generate a controlled fire situation.

Description

Equipment for fire safety testing through clean hot smoke.

The present invention relates to equipment for fire safety test using clean hot smoke in buildings, infrastructure or vehicles. With the same it aims to:

- Verify the provision of the measures of safety, particularly as regards smoke control, when A fire accident occurs.

- Verify and check the performance guidelines of the smoke control system in case of fire.

- Validate the calculation models of said system.

State of the art

It is usual that, in the technologies and fields more diverse, be investigated to achieve test equipment that reproduce the analogous conditions that will occur in the reality, but at the laboratory level in order to verify the benefits that the systems will provide in the real place Where they are installed. Thus, among others, devices of test to test detectors, (for example a smoke detector or similar appears in Patent E0910055).

In the specific field of security before fires is occurring in recent years a real revolution inspired by the growing social sensitivity towards safety of people involved in fires, addressed for the administration's response in the transformation of regulations and regulations, stimulated by new trends architectural and supported by the advancement of knowledge and related technologies

Within this revolution we can identify a major change in the priority object of security before fire, which has happened to focus absolutely on "the people ", considering these both to the occupants of the building or infrastructure, such as extinction and rescue services.

This fact is in turn implying the need of more comprehensive and complex studies of evacuation of fire scenarios in safety conditions. It claims advance research in the fields related to evacuation, more specifically the analysis of the evolution of fire, the study of human behavior before fires and the Ventilation analysis and smoke extraction.

Detailed description of the invention

The equipment for fire safety testing by clean hot smoke according to the invention, it is formed by three sets of elements:

- Tracer smoke generator.

- Fire equipment.

- Test control equipment.

The smoke generator is in turn composed of a source of tracer smoke and a flow regulation system of smoke. The source of tracer smoke is formed by a hollow drawer in whose interior is a rack in order to distribute boats of smoke provided with electric firing. Through a hopper located at continuation of the drawer the tracer smoke is directed to the suction fan inlet, which constitutes the so-called smoke flow regulation system. A conduit located at the fan outlet is responsible for driving the fumes to incorporate them into the feather of the fire.

The fire equipment consists of several fire trays with combustible fluid, located above others so many water tanks whose mission is to stabilize the temperature to achieve a constant burning rate. To generate a controlled fire situation screens are placed around of the set formed by the fire trays with their respective water tanks.

The test control equipment consists of a PC and a data logger to record the measurements of the test, as well as a control drawer that allows regulate the flow of the fan and the firing of the boats smoke.

By using the test equipment for Fire safety through clean hot smoke is intended get clean fumes at a temperature sufficient to achieve its stratification in order to verify and check the guidelines of Smoke control system performance in case of fire.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 represents a general scheme of fire safety test equipment by smoke Warm clean object of the invention.

An example of practical, non-limiting embodiment of the present invention.

In accordance with the invention, and according to the embodiment shown, the equipment for safety testing before Clean hot smoke fire basically consists of:

- a tracer smoke generator (1)

- fire equipment (2)

- a test control equipment (3).

The tracer smoke generator (1) consists of a drawer (11) with an inner rack to distribute the boats smoke, connected by a hopper (t_ {{}}) to the entrance of a fan (12) and through a hopper (t2) to a duct (13), located at the fan outlet (12) and that incorporates the smoke tracer to fire equipment (2) or fire boom - see figure one-.

The fire equipment (2) for the example of represented embodiment, is formed by four trays of fuel (24) located on four water tanks (25) and surrounded by screens (26) -see figure 1-. It is an accessory to effects of the invention the number of fuel trays (24) and water tanks (25), as long as it is maintained whenever a fuel tray (24) is placed on a fuel tank water (25).

The test control equipment (3) is composed of in turn of a PC (31) and a data logger (32) for the record of test measurements, and of a control drawer (33) for the firing of the smoke canisters and the flow regulation of the fan (2) -see figure 1-.

Invention Embodiment

The equipment for fire safety testing using clean hot smoke described above will generate a clean and colorless gas flow, but with temperature enough to achieve its stratification, coming from the combustion of a suitable fluid, that flow will be increasing and done visible by the use of tracer fumes through a contribution secondary density and speed adjustable in the center of the fire boom, thus generating a total flow of smoke design at a sufficient temperature for stratification.

To carry out the tests with the equipment Fire safety test using clean hot smoke Subject of the invention, a test point will be agreed. Will be put in set an estimated total flow of 20 m 3 / s over a period 30 minutes, in order to achieve stratification of the fumes inside the fire scenario under study that  allow to verify the performance guidelines of the control system of smoke from it. The heat output of the test shall be 2.2 MW
