Abstract
The invention relates to a container, in particular to a storage tank with a U-shaped tubular heat exchanger for storing such solution as petroleum, acid, alkali and alcohol in the petrochemical industry. The storage tank comprises a tank body and the U-shaped tubular heat exchanger. An exhaust port is formed in the top of the tank body; a discharge port and a dirt removing port are respectively formed in the bottom of the side wall of the tank body; a feed port is formed in the upper part of the side wall of the tank body; a through hole is formed in the lower part of the side wall of the tank body; one end of a heat exchange tube of the U-shaped tubular heat exchanger penetrates through the through hole to extend into the tank body; and a welding line is formed between the through hole and the heat exchange tube of the U-shaped tubular heat exchanger. The storage tank is characterized in that the welding line is connected with a cathode of a direct-current battery through a lead; an auxiliary anode device is arranged in the tank body, and is connected with liquid in the storage tank in an electric conducting manner; and an anode of the direct-current battery is connected with the auxiliary anode device through a lead. The storage tank is longer in preservation period and lower in maintenance cost.
Description
Technical field
The present invention relates to a kind of container, specifically for storing the storage tank with U-shaped pipe heat exchanger of the solution such as oil, soda acid, alcohol in petroleum chemical industry。
Background technology
Storage tank with U-shaped pipe heat exchanger is a kind of container for storing the solution such as oil, soda acid, alcohol。It mainly includes tank body and U-shaped pipe heat exchanger。Air vent is arranged at the top of described tank body, discharging opening and sewage draining exit are arranged respectively at the bottom of its sidewall, charging aperture is arranged at the top of its sidewall, through hole is arranged at the bottom of its sidewall, heat exchanger tube one end of described U-shaped pipe heat exchanger extend in tank body through this through hole, and is welded with weld seam between the heat exchanger tube of through hole and U-shaped pipe heat exchanger。This storage tank with U-shaped pipe heat exchanger is after storing liquid, owing to being used for making the welding metal material of weld seam and for making the difference between the metal material of storage tank, so there being potential difference between weld seam and storage tank, thus form galvanic corrosion in commissure, the corrosion rate of the liquid butt welded seam in quickening tank body, shorten the maintenance period of storage tank, add maintenance cost。
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of storage tank with U-shaped pipe heat exchanger, and the maintenance period of this storage tank is longer, and maintenance cost is relatively low。
For solving the problems referred to above, it is provided that techniques below scheme:
The storage tank with U-shaped pipe heat exchanger of the present invention includes tank body and U-shaped pipe heat exchanger。Air vent is arranged at the top of described tank body, discharging opening and sewage draining exit are arranged respectively at the bottom of its sidewall, charging aperture is arranged at the top of its sidewall, through hole is arranged at the bottom of its sidewall, heat exchanger tube one end of described U-shaped pipe heat exchanger extend in tank body through this through hole, and has weld seam between the heat exchanger tube of through hole and U-shaped pipe heat exchanger。Being characterized in that described weld seam is connected by the negative electrode of wire and a dc-battery, have auxiliary anode device in described tank body, auxiliary anode device and the liquid in storage tank are in being conductively connected, and the anode of described dc-battery is connected with this auxiliary anode device by wire。
Wherein, the negative electrode of described dc-battery is connected to copper sulfate reference electrode device by wire, and has voltmeter on this section lead。
Wherein, described auxiliary anode device is graphite block, and the lower end of graphite block is arranged in the liquid of tank body。
Take above scheme, have the advantage that
Owing to the weld seam of the storage tank with U-shaped pipe heat exchanger of the present invention is connected by the negative electrode of wire and a dc-battery, auxiliary anode device is had in described tank body, auxiliary anode device and the liquid in storage tank are in being conductively connected, and the anode of dc-battery is connected with this auxiliary anode device by wire。Therefore, utilize dc-battery to supplement electronics to commissure, the potential difference between weld seam and storage tank is eliminated, thus avoiding galvanic corrosion, the corrosion rate of the liquid butt welded seam slowed down in tank body so that maintenance period is extended, and reduces maintenance cost。
Accompanying drawing explanation
Fig. 1 is the structural representation of the storage tank with U-shaped pipe heat exchanger of the present invention；
Fig. 2 is the I portion enlarged diagram of figure。
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail。
As depicted in figs. 1 and 2, the storage tank with U-shaped pipe heat exchanger of the present invention includes tank body 1 and U-shaped pipe heat exchanger 8。The top processing of described tank body 1 has air vent 3, the bottom of its sidewall has processed discharging opening 10 and sewage draining exit 9 respectively, the top processing of its sidewall has charging aperture 2, the bottom processing of its sidewall has through hole 12, heat exchanger tube one end of described U-shaped pipe heat exchanger 8 extend in tank body 1 through this through hole 12, and has weld seam 11 between the heat exchanger tube of through hole 12 and U-shaped pipe heat exchanger 8。Described weld seam 11 is connected by the negative electrode of wire and a dc-battery 5, auxiliary anode device 4 is had in described tank body 1, this auxiliary anode device 4 is graphite block, the lower end of graphite block is arranged in the liquid of tank body 1, so that auxiliary anode device 4 and the liquid in storage tank are in being conductively connected, the anode of described dc-battery 5 is connected with this auxiliary anode device 4 by wire。The negative electrode of described dc-battery 5 is connected to copper sulfate reference electrode device 6 by wire, and has voltmeter 7 on this section lead。
Dc-battery 5 should be utilized to weld seam 11 place to supplement electronics with the storage tank of U-shaped pipe heat exchanger, potential difference between weld seam 11 and storage tank is eliminated, thus avoiding galvanic corrosion, the corrosion rate of the liquid butt welded seam 11 slowed down in tank body 1, maintenance period is extended, reduces maintenance cost。
