Definitions

• the present invention relates to a unit for installing apparatuses in general in areas with a dangerous atmosphere.
• the aim of the invention is to solve the problem described above by providing a unit for installing apparatuses in general in areas with a dangerous atmosphere, which allows to provide a ready-made modular element which can be installed and used immediately, with the additional advantage of being able to remove it and reuse it once it is no longer needed in such area.
• an object of the invention is to provide a unit which can be transported and positioned easily with normally usable means, such as land, ship, or airborne transport, with the advantage of being able to handle easily the assembly, which is already adequately preset.
• Another object of the present invention is to provide a unit which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
• Still another object of the present invention is to provide a unit which can be obtained easily starting from commonly commercially available elements and materials and is further competitive from a merely economical standpoint.
• a unit for installing apparatuses in general in areas with a dangerous atmosphere characterized in that it comprises a modular body which can be transported to the site of use and defines internally a compartment with a safe atmosphere, a pressurization section, for maintaining within said compartment an overpressure with respect to the outside, and a climate control section, with a condenser/evaporator assembly arranged outside said compartment and provided with a protected structure for use in a dangerous atmosphere, being associated with said body.
• Figure 1 is a schematic view of an embodiment of the unit according to the invention
• Figure 2 is a schematic external view of the pressurization section
• Figure 3 is a sectional view, taken along a longitudinal plane, of the pressurization section and of the climate control section;
• Figure 4 is a top plan view of the pressurization section;
• Figure 5 is a top plan view of the climate control section.
• the unit for installing apparatuses in general in areas with a dangerous atmosphere has the peculiarity that it comprises a modular body, generally designated by the reference numeral 1, which is provided advantageously by a container with standard dimensions, which is structured so as to define inside it a compartment 2 with a safe atmosphere, to the inside whereof access is ensured by a hermetic door 3.
• the modular body 1 has the peculiar characteristic that it can be transported easily while already preset with the several apparatuses described hereinafter, directly to the site of use, by way of ordinary means of transport, thus facilitating the placement of the apparatus in sites having high logistic difficulties due to natural, atmospheric and structural conditions. Moreover, in case of reuse on another site and in a new context, the modular body lends itself easily to a new installation and use, since each unit is provided preassembled, tested and ready for entering service.
• Each modular body has a pressurization section, generally designated by the reference numeral 10, which has the peculiarity of comprising a monobloc unit with two independent sections, designated by the reference numerals 11 and 12, which are accommodated in a bay 13 which is closed by a hermetic panel 14, which allows access in case of malfunctions and maintenance interventions.
• the section 10 has a high-efficiency air filter 15 at which there is, for each independent section, a shutter 16 which excludes selectively one section or the other in case of maintenance interventions or faults.
• differential pressure gauge 17 which detects the external atmospheric pressure with respect to the real overpressure provided within the compartment 2.
• a separating shutter 18 which excludes the overpressure flow from the safe area if the pressurization assembly is blocked.
• a preheater 19 which is arranged at the safe atmosphere intake, designated by the reference numeral 9.
• the unit further comprises a climate control section, generally designated by the reference numeral 20, which has an evaporator condenser assembly 21 which is provided with a protected structure for use in a dangerous atmosphere and on which an electric fan condenser 22 acts which is also provided within a protected structure for use in a dangerous atmosphere.
• a climate control section generally designated by the reference numeral 20
• an evaporator condenser assembly 21 which is provided with a protected structure for use in a dangerous atmosphere and on which an electric fan condenser 22 acts which is also provided within a protected structure for use in a dangerous atmosphere.
• an electric heater 30 Inside the compartment 2 there are advantageously an electric heater 30, a filter 31 for the air of the compartment, and a motorized evaporator climate control element 32, which can be used in a pressurized safe atmosphere area.
• the unit according to the invention is also provided with a temperature regulation system adapted to provide temperatures inside the modules from +25°C to +5°C with a hydrometer degree of approximately 60%, considering environmental temperatures with thermal variations from -40 0 C to +50 0 C, thus allowing installation of the several units in highly challenging environmental areas in terms both of temperature and in case of highly corrosive atmosphere.
• the unit contains and uses a double circuit air battery known as condenser/evaporator and is installed externally in a dangerous atmosphere and therefore is provided with a protected structure. Depending on the external environmental conditions, the unit allows automatic reversal of the refrigeration cycle, heating or cooling the safe area.
• condenser/evaporator a double circuit air battery known as condenser/evaporator
• pressurization system Since the pressurization system is built as two independent pressurizing sections in standby, it ensures constant extraction of clean atmosphere and the presence of overpressure ensures that no entry of dangerous atmosphere occurs when the door is opened.
• Pressurization is controlled by means of differential pressure gauges between the outside and the inside in safety with two-step detection.
• the pressure gauge automatically activates the second section of the unit, reestablishing correct pressurization.
