Use of such a lance allows to reclaim areas attacked by pathogenic and/or toxic agents of the nuclear, bacteriological, chemical and/or radiological types.
  • jet lances are known for reclaiming areas attacked by pathogenic and/or toxic agents of the nuclear, bacteriological, chemical and/or radiological types. These lances typically allow the relevant area to be sprayed with a mixture of a working fluid, generally water, and a detoxification/decotamination product.
  • Italian Patent application No. VI2004A000150 in the name of the same applicant, discloses a jet lance having all the features of the preamble of claim 1.
  • a main object of the present invention is to overcome the above drawbacks, by providing a jet lance that is highly efficient and relatively cost-effective.
  • a particular object is to provide a jet lance that allows a user to monitor the temperature of the inflowing and/or outflowing sprayed fluid.
  • a jet lance as claimed in claim 1, comprising at least one first conduit for feeding a pressurized fluid, said at least one first conduit having an inlet for connection to an external working fluid supply line and an outlet having a first jet nozzle, said at least one first conduit having means for supplying a decontamination/detoxification product which is susceptible of being mixed with the working fluid upstream from the first jet nozzle, characterized in that it comprises means for sensing temperature in the first conduit, said sensing means having a temperature display visible from the outside.
  • the lance according to the invention allows a user to constantly and promptly monitor the working fluid temperature and take actions whenever such temperature deviates from the desired values.
  • a protective casing may be provided, which is designed to be held in a user's hand and contains the first conduit, the casing having an optically transparent portion through which the display is visible.
  • the lance according to the invention allows simple and direct monitoring of the conveyed fluid temperature.
  • the invention in another aspect, relates to a process for making the above jet lance as defined in claim 13, which comprises the steps of providing a jet lance which comprises at least one first conduit for feeding a pressurized fluid, said at least one first conduit having an inlet for fluid connection to an external working fluid supply line and an outlet, said at least one first conduit having means for supplying a decontamination/detoxification product which is susceptible of being mixed with said working fluid upstream from said outlet, installing temperature-sensing means on said at least one first conduit, said sensing means having a temperature display visible from the outside.
  • a jet lance is obtained which allows a user to constantly and promptly monitor the working fluid temperature and take actions whenever such temperature deviates from the desired values.
  • the process of the invention is also suitable for making changes to existing and operating jet lances.
  • the jet lance according to the invention is particularly useful for spraying decontamination/detoxification products on areas attacked by toxic and/or pathogenic agents of the nuclear, bacteriological, chemical and/or radiological type to reclaim them.
  • the lance 1 essentially comprises an outer casing composed of two half-shells 2, 2', which encloses a hydraulic circuit 3 having an inlet 4 for connection to an external line for supply of a working fluid, possibly water at predetermined pressure and temperature, and an outlet 5.
  • the circuit 3 comprises a first conduit 6, a second conduit 7 connected and parallel to the first one and a third conduit 8, which is in fluid communication with the other two, and on which a first control lever 8' is mounted fitted for controlling the flow of the working fluid.
  • the third conduit 8 has a first end 9 with a fitting that defines an inlet 4 and the opposite end 10 connected to a flow selector/deflector 11.
  • a flow selector/deflector 11 has a first outlet 12 connected to the first conduit 6 and a second outlet 13 connected to the second conduit 7, which can be selected by suitably operating a second control lever 13'.
  • the flow selector/deflector 11 may be configured in accordance with the teachings of the Italian Patent application VI2004A000150 , in the name of the same applicant.
  • the first and second conduits 6, 7 have respective delivery nozzles 14, 15 defining the outlet 5 of the circuit 3.
  • Such delivery nozzles 14, 15 may be configured according to the teachings of the Italian Patent application VI2004A000150 , in the name of the same applicant.
  • the delivery nozzle 14 of the first conduit 6 may be of the of the dual head type and may be selected by means of a gravity feed valve, for quick and easy adjustment of the desired delivery width.
  • the first conduit 6 has means for supplying a decontamination/detoxification product, which means are generally designated by numeral 16.
  • Such supply means essentially include a product cartridge 17 which is removably attachable to the casing at the half-shell 2, a hose 18 and a Venturi ejector 19 placed on the first conduit 6 for connection between the latter and the cartridge 17. More precisely, the ejector 19 has the inlet 20 and the outlet 21 connected to the first conduit 6 and a throat 22 that is connected to the end 23 of the conduit 18, which conduit has the other end in fluid communication with the cartridge 17.
  • the lance 1 may have a backpack-type product container, in lieu of or connected to the cartridge 17, for the user to carry it on his/her back, without departure from the claimed scope, as defined by the contents of the annexed claims.
  • An analog or digital thermometer 24 is mounted to the first conduit 6, and has a display 25 visible from the outside.
  • thermometer 24 may be of any type without departure from the inventive scope as defined by the contents of the annexed claims.
  • a contact thermometer may be used, with the sensor thereof being laid on the outer surface of the conduit 6 or directly in contact with the fluid flowing through the conduit 6, i.e. located within the latter.
  • thermocouple may be used, which is located in the first conduit 6 and connected to a digital display visible from the outside.
  • the protective casing 2, 2' shall have an optically transparent portion 26 and the display 25 shall be placed thereat.
  • thermometer 24 is located upstream from the Venturi ejector 19. Thus, temperature is sensed on the working fluid prior to mixing thereof with the decontamination/detoxification product.
  • thermometer 24 may be located in any position, either upstream or downstream from the Venturi ejector 19, provided it is mounted to the first conduit 6, without departure from the inventive scope, as defined by the contents of the annexed claims.
  • a flow regulating member 27, possibly a throttle, may be provided on the second conduit 7.
  • the lance 1 functions as follows.
  • the inlet 4 has to be first connected to an external working fluid supply line, such as Sanijet ® C921, sold by Cristanini S.p.A., then a cartridge of decontamination/detoxification product, such as BX24®, also sold by Cristanini S.p.A., may be attached to the casing 2.
  • an external working fluid supply line such as Sanijet ® C921, sold by Cristanini S.p.A.
  • BX24® also sold by Cristanini S.p.A.
  • the working fluid flows into the third conduit 8 to the selector/deflector 11.
  • the control lever 13' By appropriately operating the control lever 13' so that the outlet 13 connected to the second conduit 7 is occluded, the working fluid is caused to flow into the first conduit 6.
  • the working fluid passes through the Venturi ejector 19, thereby generating a negative pressure, caused by the Venturi effect, to draw the decontamination/detoxification product from the cartridge 17.
  • the decontamination/detoxification product will pass through the conduit 18 and the throat 22 and mix with the working fluid. Now, the resulting mixture will reach the nozzle 14 to be delivered to the area to be reclaimed.
  • the inventive jet lance may be obtained by providing a jet lance as described above, such as the lance Sanijetgun® sold by Cristanini S.p.A. and essentially fitting it with temperature-sensing means as defined above, to be mounted to the conduit in which the working fluid is mixed with the decontamination/detoxification product.
  • a jet lance as described above, such as the lance Sanijetgun® sold by Cristanini S.p.A. and essentially fitting it with temperature-sensing means as defined above, to be mounted to the conduit in which the working fluid is mixed with the decontamination/detoxification product.
  • an optically transparent portion 26 may be formed in the half-shell 2' of the protective casing, and the display 25 of the temperature sensing means may be placed at such optically transparent portion 26.
  • the optically transparent portion 26 may be also formed on the half-shell 2 and/or portions 26 may be provided in any number without departure from the inventive scope as defined by the contents of the annexed claims.
