Abstract
The utility model discloses an anti-oxidation device of a heat conduction oil system, which comprises an expansion slot communicated with a heat conduction oil pipeline, and is characterized in that the top of the expansion slot is connected with a floating gas tank by a gas pipeline; the floating gas tank is reversely buckled on the liquid surface in a balanced way; and the expansion slot and the floating gas tank are internally filled with inert gas. The anti-oxidation device of the heat conduction oil system is provided with the floating gas tank, so that the gas pressure in the expansion slot can be adjusted at the right time, the internal pressure is ensured to be stable, and the sealing effect is good; furthermore, heat conduction oil is not easily contacted with the air and oxidized, so that the cost of the device is low.
Description
Technical field
The utility model relates to a kind of anti-oxidation device that comprises the heat-conducting oil system of expansion slot.
Background technology
For a heat-conducting oil system, because factors such as design, operating aspect, conduction oil in expansion slot or the storage tanker can be exposed in the air, if contact with air, oxidizing reaction will take place, the fluctuation of ad hoc system thermal load is bigger, can make the oily temperature rise of expansion slot, when spending above 60, speed of response can obviously be accelerated, make its oxidation deterioration, kinematic viscosity increase, slow, the cracking aggravation of heat transfer, seriously can cause safety misadventure.Conduction oil oxidation reason mainly is exactly the direct contact that volume change is brought air and conduction oil in the conduction oil process of expansion and contraction, and the elevated tank temperature is high more, potential difference changes more greatly, and the oxidation probability is high more.
Each heat-conducting oil furnace user, generally two kinds of anti-oxidant measures of Cai Yonging now.A kind of is nitrogen envelope method, as shown in Figure 1, connects on elevated tank 3-1 and mends nitrogen valve 9-1 and decompression exhaust-valve 9-2, and when the conduction oil expanded by heating, the nitrogen among the elevated tank 3-1 is discharged from the decompression exhaust-valve; When the shrinkage of conduction oil drop in temperature, from mend nitrogen valve, replenish certain nitrogen, the equilibrium of pressure in the maintenance system.Though this method can prevent the problem of conduction oil and air catalytic oxidation well, but system is in operation and will consumes certain nitrogen, the financial cost height.Another kind method is a cold oil envelope method, as shown in Figure 2, expansion slot 3-1,3-2 is connected with cold oil container 10-1,10-2, this method is in the bigger place of thermal load fluctuation, oil in the cold oil envelope all may be pumped in the expansion slot, make liquid sealing pipe blank, thereby lose closing function.
The utility model content
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, and the anti-oxidation device that a kind of financial cost is low, can effectively prevent the conduction oil oxidation is provided.
Technical scheme: the anti-oxidation device of heat-conducting oil system described in the utility model, it is mainly conceived is that expansion slot is linked to each other with a unsteady gas tank, charge into unreactable gas in expansion slot and unsteady gas tank, the conduction oil in the system expands with heat and contract with cold to change and makes unreactable gas shift between expansion slot and unsteady gas tank.The utility model device comprises the expansion slot that communicates with heat conducting oil pipe, and the top of described expansion slot links to each other with a unsteady gas tank by gas passage, and the gas tank balance of floating tips upside down on the liquid level; Charged into unreactable gas in described expansion slot and the described unsteady gas tank.
In order to make the counterbalance effect of unsteady gas tank relatively good, the both sides, top of described unsteady gas tank are by two fixed pulley balances.
Described unsteady gas tank tips upside down in the container that fills liquid, and the bottom of container is provided with discharge port, the convenient liquid level water level of adjusting.
Described expansion slot is two, is respectively elevated tank and Lower tank, and two expansion slots link to each other with unsteady gas tank simultaneously.
Described unreactable gas can be selected nitrogen relatively more commonly used, and financial cost is low.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, the utility model is adjusted the gaseous tension in the expansion slot by unsteady gas tank is set in good time, press stable in guaranteeing, it is oxidized that good sealing effect, conduction oil are difficult for touching air, and installation cost is low; 2, the utility model apparatus structure is reasonable, good sealing effect, and the residual moisture of conduction oil is convenient discharges.

The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 3, a kind of anti-oxidation device of heat-conducting oil system, its heat-conducting oil system comprises oil oven 1 and processing unit 8, heat conducting oil pipe connects expansion slot 3 by disconnector 2, described expansion slot is two, be respectively elevated tank 3-1 and Lower tank 3-2, the top of two expansion slots links to each other with unsteady gas tank 4 by gas passage simultaneously, and gas tank 4 balances of floating tip upside down on the liquid level; Charged into nitrogen in described expansion slot 3 and the described unsteady gas tank 4; The both sides, top of described unsteady gas tank 4 are connected with the thing piece by two fixed pulleys 5 carries out balance to the gas tank that floats; Gas tank 4 volume size of floating expand according to system's conduction oil and decide with the overall product moment that shrinks.
Described unsteady gas tank tips upside down in the container 6 that fills liquid, and the bottom of container 6 is provided with discharge port 7.
In the conduction oil process of expansion and contraction, the gas compartment is adjusted in good time in the expansion slot, presses stable in guaranteeing.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
