PURPOSE:To make it possible to prepare an unused pressure vessel before a pressure vessel is emptied by announcing that the quantity of deodorization liquid in the pressure vessel has decreased when the quantity of vapor of liquefied gas is found to have exceeded a predetermined quantity by means of a detecting means. CONSTITUTION:A deodorizer is of a wall type, in which the air introduced through a suction port 10 by means of a fan 2 is deodorized while it passes through a deodorizing filter 3 on which deodorization liquid has been sprayed, after which the air is discharged out of a casing 1 through a blowoff port 11. When the quantity of the deodorization liquid in a pressure vessel 41 has decreased after actuation of the deodorizer, pressure gas blows off together with the deodorization liquid from a blowoff part when a valve 41a is opened, so that the pressure gas together with the deodorization liquid 62 flows into a liquid pipe 42. Hence resistance values between electrodes 53, 54, when the deodorization liquid is sprayed, increase and output signals of a detection circuit 66 are lowered. When the output signals of the circuit 66 have become lower than threshold voltage Vth, a control circuit 70 judges that the quantity of deodorization liquid in the vessel 41 has decreased and causes an indicating lamp 68 to flicker. |
