COB catalyzes the natural like things fuel gas filling equipment to act according to various enterprises service condition to design the series complete addition equipment, satisfies the enterprise to produce the need. Before not appropriate addition equipment, the people use generally add the smelly equipment to satisfy the chemical additive joined, in the past mainly what used was drips into the type and the absorption type two ways. Drips into the type is (smelly medicinal preparation) drips into the chemical additive by the storage tank through the narrow tube in the fuel gas main pipe, bubble quantity may carry on the adjustment through the needle valve; Because this way the bubble mouth area is very small, the request chemical additive has the big vapor tension. Is precisely this kind of characteristic, it can only use in the fuel gas current capacity not big place. Absorption in the formula divides into the fabric core type, to spray the type and the bubble type and so on, they are through the expanded chemical additive (smelly medicinal preparation) the evaporation area, increases the chemical additive (smelly medicinal preparation) joins the quantity, suits for the great current capacity fuel gas replenishment.

Drips into the type and the absorption type are unable to control the chemical additive accurately (smelly medicinal preparation) quantity, moreover, when the fuel gas current capacity changes needs the man-power to adjust the chemical additive according to the experience (smelly medicinal preparation) the quantity, not easy assurance.

At present uses many for the semiautomatic replenishment way and the completely automatic replenishment way. They are (smelly medicinal preparation) extract through the miniature metering pump the chemical additive from the cushion pot, infiltrate to the fuel gas main pipe. The miniature metering pump generally for the double ram pump and the diaphragm pump two kinds, infiltrates in the fuel gas main pipe's chemical additive through the metering pump (smelly medicinal preparation) the quantity to be possible to control is quite accurate. The semiautomatic replenishment way equipment construction cost is low, suits in the current capacity stable place. Its must act according to the current capacity which usually counts, calculates chemical additive each hour to join the quantity, by establishes artificially, the metering pump then automatically infiltrates the chemical additive according to the setting value to the fuel gas main pipe in; The completely automatic replenishment way gives the computer by the current capacity detector set the signal feedback, the computer and each cubic meter fuel gas which establishes has needed according to the fuel gas current capacity the replenishment quantity, through controls the metering pump to adjust the malodorant quantity the size.

COB catalyzes the natural like things fuel gas filling equipment to use the PLC programmable control, automatic, manual cuts willfully, through the frequency establishment may guarantee that adds the medicinal preparation density evenly in the fuel gas current capacity permission's scope stable. This aircraft uses the explosion-proof design, the entire airtight work, the mutual lack of understanding antiseptic treatment, is suitable for the liquid state medicament which increases each kind flammable, explosive, easy to volatilize, the control hypothesis, the increase medicament measurement is accurate, but the setting range is big.

The COB filling equipment not only uses the craft which the metering pump controls to complete adds the fluid the procedure also to use the quota compulsion gasification the craft to urge COB to catalyze the assistant gasification, through the quota controller balanced input fuel gas pipeline, realizes the catalyst and the fuel gas synchronization completes the gasified work, this method operation is relatively simple, safe, suits each kind of current capacity with to be mad the unit.

COB in national and so on US, France, Germany, Japan, India uses not only set up the COB brand superiority, will conserve energy, the environmental protection idea promotion to be more thorough, COB will make the positive endeavor for the numerous enterprise's development.
