Description

Technical Field

[0001] The utility model belongs to the technical field of cooling systems, and in particular relates to an activated carbon filter for water treatment of a high-voltage direct current transmission converter valve cooling system. Background Art

[0002] The converter valve is the core equipment of the DC transmission system. The performance of the converter valve directly affects the working stability of the entire DC transmission. However, the converter valve generates a lot of heat during operation. The increase in the temperature of the converter valve will greatly reduce its working performance. In order to ensure the working temperature of the converter valve, it is usually necessary to equip a set of water cooling equipment to exchange the heat generated by the converter valve to the outside world.

[0003] As an outdoor heat exchange device for the DC converter valve cooling equipment, the cooling tower continuously sprays external cold water onto the cooling tower heat exchange coil to achieve efficient cooling and rapid temperature reduction. However, the untreated industrial tap water contains a large amount of impurities, which can easily cause serious scaling of the heat exchange coil and affect the heat exchange efficiency. This requires the converter station to be frequently shut down for maintenance and descaling, which seriously affects the stability of DC power transmission.

[0004] As a key equipment for spray water treatment, the activated carbon filter device can remove impurities such as macromolecular organic matter, colloids, odors, residual chlorine, etc. in the water. At the same time, the activated carbon filter layer can further remove suspended matter, mechanical particles and other impurities in the water through mechanical filtration.

[0005] Activated carbon is somewhat corrosive. First, the metal ions it adsorbs will cause certain corrosion to the tank body. Second, the activated carbon and the tank body form electrochemical corrosion, which accelerates the corrosion of the metal tank body. Therefore, the inner wall of the activated carbon filter device needs to consider the anti-corrosion process.

[0006] However, the existing activated carbon filter device in the prior art is difficult to inspect and maintain, and it is difficult to observe the condition of the filter material. At the same time, the internal space of the tank of the existing activated carbon filter device is small, and it is difficult to perform rubber lining anti-corrosion process inside.

The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.

[0035] like Figure 1 and Figure 4-6 As shown, an activated carbon filter for water treatment in a high-voltage direct current transmission converter valve cooling system includes a support system 100, a pipeline system 200, a carbon filter tank 300, and an instrument system 400.

[0036] The support system 100 is composed of a base 110, a pipe support 120 and a terminal box support 130;

[0037] The pipeline system 200 is fixed on the pipeline support 120 through a pipe code. The pipeline system 200 includes an inlet pipeline 210, a connecting pipeline 220, a sewage pipeline 230, a backwash pipeline 240 and a water outlet pipeline 250, which are connected in sequence to form a pipeline system pipeline.

[0038] The pipeline system 200 further includes a water inlet 211 , a water outlet 251 , a backwash outlet 241 , and a sewage outlet 231 .

[0040] like Figure 2 , Figure 3 As shown, the charcoal filter tank body 310 also includes a lifting ear 311 located at the top of the charcoal filter tank body 310, a feeding port 312 located at the top of the charcoal filter tank body 310, a middle manhole 313 located in the middle of the charcoal filter tank body 310, a bottom manhole 314 located at the bottom of the charcoal filter tank body 310, a charcoal filter tank body inlet pipe 315 located on the side of the charcoal filter tank body 310, a charcoal filter tank body outlet 316 located at the bottom of the charcoal filter tank body 310, two sight glasses 317 located on the sides of the charcoal filter tank body 310 and four supporting legs 318 at the bottom of the charcoal filter tank body 310.

[0041] It is noteworthy that in the present invention, the viewing mirror, i.e., the observation window, can visually observe the situation inside the carbon filter tank, which helps to understand the filtering situation in a timely manner.

[0042] Specifically, the connecting pipeline 220 of the pipeline system 200 is also connected to the carbon filter tank inlet pipeline 315, and the backwash pipeline 240 of the pipeline system 200 is also connected to the carbon filter tank outlet 316.

[0043] One end of the carbon filter tank connecting pipeline 330 is connected to the carbon filter tank inlet pipeline 315 , and the other end is connected to the water distributor pipeline 340 .

[0044] The water distributor pipeline 340 is fixed at the top of the carbon filter tank, and 8 filter elements are evenly distributed around the water distributor pipeline 340.

[0045] like Figure 3 As shown, the carbon filter separator 350 also includes filter caps 351 evenly distributed above the carbon filter separator 350 and a separator support 352 located at the bottom of the carbon filter separator 350, and the separator support 352 is welded to the inside of the lower head at the bottom.

[0046] In a preferred but non-limiting embodiment of the present invention, three circular legs are provided at the bottom of the carbon filter partition 350, which does not affect the strength of the partition and solves the problem of rubber lining on the bottom surface of the partition.

[0047] Further preferably, a water distributor is provided at the top of the carbon filter tank, and water enters the carbon filter layer evenly through the water distributor. A carbon filter baffle 350 and a filter cap 351 are provided at the bottom of the carbon filter tank, which can allow water to pass through but prevent activated carbon from passing through to obtain filtered water.

[0048] The instrument system 400 is an instrument installed on a pipeline system.

The automation program is highly automated and can perform backwashing operations by accumulating operating time and accumulating operating flow, which is convenient for daily maintenance.

[0051] During normal operation, water enters from the water inlet, enters the activated carbon layer through the water distributor on the top of the filter, and after being filtered by the activated carbon, the water flows out from the baffle filter cap, and finally flows out as pure water from the water outlet. During backwashing, water enters from the backwash port, and the backwash water flows in the reverse direction into the filter layer of the carbon filter tank to remove adsorbed substances and extend the life of the activated carbon. Finally, the sewage is discharged from the sewage outlet. The forward wash water enters from the water inlet, passes through the filter layer from top to bottom, and washes away the impurities remaining after backwashing. Finally, the sewage is discharged from the sewage outlet.

[0052] The beneficial effect of the present invention is that, compared with the prior art,

[0053] (1) The utility model provides an activated carbon filter device that can automatically switch between normal operation, backwashing and forward washing processes. The activated carbon filter device uses multiple electric valves to achieve a variety of combinations according to process requirements. The automation program is high and the backwash operation can be performed by accumulating the operating time and the accumulated operating flow, which is convenient for daily maintenance;

[0054] (2) The activated carbon filter device is also provided with an observation window, which can visually observe the situation inside the carbon filter tank. At the same time, the interior of the carbon filter tank needs to be lined with rubber for corrosion protection. The bottom space of the carbon filter partition is limited, and the mesh filter plate reinforcement ribs designed in the past are difficult to line the bottom of the partition with rubber. In order to ensure the strength of the partition and solve the rubber lining problem, the utility model sets three partition support members at the bottom of the partition, which does not affect the strength of the partition and solves the problem of rubber lining on the bottom of the partition.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
