Description

TECHNICAL FIELD

[0001] The present application relates to the power industry cleaning technical field, especially to a spray cleaning device for air cooler of converter station. BACKGROUND

[0002] The chemical spray cleaning technology is early and widely used in petrochemical, steelmaking and other industries, and its cleaning process is quite mature. The cleaning tool mainly consists of a spray device installed above the air cooler tube bundle, a cleaning liquid collection pool on the ground and a high-pressure circulating water pump. After the cleaning starts, the chemical reagent in the cleaning liquid collection pool is pumped to the spray device by the high-pressure water pump, the cleaning liquid is uniformly sprayed on the surface of the air cooler radiator, then penetrates the tube row through the air duct to the cleaning liquid collection pool below, so that the air cooler radiator can be cleaned repeatedly.

[0003] The air cooler of the converter station is similar to the petrochemical and steelmaking industries in material and structure, but its cleaning process has special requirements, specifically in the following aspects:

[0004] (1) Leakage protection: the chemical cleaning reagent is prepared by using acidic or alkaline chemicals, which is still corrosive after dilution. The existing cleaning process has a 3-5 meter drop from the high spray to the return to the cleaning pool, so some cleaning liquid will inevitably splash out during the spray cleaning process, flowing to the ground or into the air. The air cooler of the converter station has a complex operating environment, surrounded by equipment that is prone to corrosion. The cleaning liquid that enters the air can cause corrosion hazards to the surrounding equipment. In addition, the cleaning liquid that flows to the ground will be discharged into the sewer with the waste water, causing pollution to the surrounding rivers or farmland, which is not conducive to environmental protection.

[0005] (2) Cleaning time: the converter station will organize a large-scale power outage maintenance once a year, which takes about a week. Due to the complex types and large number of equipment in the converter station, the maintenance of all equipment in the station needs to be completed during the overhaul. The cleaning of the air cooler radiator will affect the maintenance of other equipment, so the cleaning time must be compressed. The cleaning liquid collection pool of the existing cleaning process is usually surrounded by acid and alkali resistant plastic tarpaulin in the shape of a fish pool, which is time-consuming and laborious to build and dismantle, and is not convenient to move. The dirt and impurities cleaned flow directly into the cleaning liquid collection pool with the spray water, which can easily block the circulating pump inlet, causing temporary stoppage and delaying the cleaning time, affecting the cleaning efficiency. SUMMARY

[0006] The present application provides a spray cleaning device for air cooler of converter station to solve the problem that the existing spray cleaning equipment is prone to splash cleaning liquid during the spray cleaning process, causing corrosion hazards to the surrounding equipment and causing pollution.

[0007] The embodiment of the present application discloses the following technical scheme:

[0008] A cleaning and spraying device for an air cooler of a converter station, comprising a cleaning liquid collecting pool, a pressure pump, a first pipeline, a spray head, a cleaning liquid recycling mechanism and a second pipeline; the inlet end of the pressure pump extends into the cleaning liquid collecting pool, the outlet end of the pressure pump is in communication with one end of the first pipeline, the other end of the first pipeline is in communication with the spray head, the cleaning liquid recycling mechanism is in communication with one end of the second pipeline, the other end of the second pipeline extends into the cleaning liquid collecting pool, the spray head is located above the air cooler, and the cleaning liquid recycling mechanism is located below the air cooler.

[0009] The cleaning liquid collecting pool is used for storing cleaning liquid, and the cleaning liquid comprises an aluminum corrosion inhibitor and an alkaline solution, and the aluminum corrosion inhibitor comprises components in the following weight percentages: 30-40% of sodium alginate, 25-32% of trisodium silicate, 15-25% of potassium sodium tartrate, 3-8% of calcium hydroxide, 5.5-13% of aminoacetic acid and 1-3% of dodecyl phenol polyoxyethylene ether.

[0010] The technical scheme of the embodiment of the present application has the following beneficial effects:

[0011] The cleaning and spraying device for the air cooler of the converter station can reduce cleaning liquid leakage, save a large amount of cleaning liquid, reduce the number of times of stopping machine to supplement cleaning liquid, further improve cleaning efficiency, speed up lean maintenance of the converter station, and save construction cost for a construction enterprise.

Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0015] The embodiment of the present application discloses a cleaning and spraying device for an air cooler of a converter station. As shown inFigure 1 As shown, the cleaning spray device comprises a cleaning liquid collecting pool 101, a pressure pump 102, a first pipeline 103, a spray head 104, a cleaning liquid recovery mechanism and a second pipeline 105. The pressure pump 102 is a high-pressure pump. The inlet end of the pressure pump 102 extends into the cleaning liquid collecting pool 101, the outlet end of the pressure pump 102 is communicated with one end of the first pipeline 103, the other end of the first pipeline 103 is communicated with the spray head 104, one end of the second pipeline 105 is communicated with the cleaning liquid recovery mechanism, and the other end of the second pipeline 105 extends into the cleaning liquid collecting pool 101. The spray head 104 is located above the air cooler 201, and the cleaning liquid recovery mechanism is located below the air cooler 201. The cleaning liquid collecting pool 101 is used to store the cleaning liquid.

[0016] In use, the pressure pump 102 is opened, and the pressure pump 102 draws the cleaning liquid in the cleaning liquid collecting pool 101 to flow to the spray head 104 through the first pipeline 103, and the cleaning liquid is sprayed out of the spray head 104 to the surface of the air cooler 201, so that the cleaning liquid cleans the dirt on the surface of the air cooler 201. The sprayed cleaning liquid finally falls into the cleaning liquid recovery mechanism and flows into the cleaning liquid collecting pool 101 through the second pipeline 105 for recycling for the next cycle.

[0017] Specifically, the cleaning liquid recovery mechanism comprises a liquid receiving disc 106, a cleaning liquid recovery tank 107 and a water suction pump 108. The liquid receiving disc 106 can be made of acid and alkali resistant plastic tarpaulin by cutting and sewing. The liquid receiving disc 106 can be placed on a support frame 109. The support frame 109 can be composed of four columns and two rings by welding, one ring is welded at the top end of the four columns, and the other ring is welded at the bottom end of the four columns. The diameter of the ring is slightly larger than the diameter of the air duct of the fan 202 below the air cooler 201. The liquid receiving disc 106 is installed in the ring at the top end of the column. The cleaning liquid recovery tank 107 is located below the liquid receiving disc 106 and can be placed between the four columns. The cleaning liquid recovery tank 107 can be a circular plastic ton barrel. The liquid outlet at the bottom of the liquid receiving disc 106 is communicated with the liquid inlet at the top of the cleaning liquid recovery tank 107, the inlet end of the water suction pump 108 is communicated with the liquid outlet near the bottom of the cleaning liquid recovery tank 107, and the outlet end of the water suction pump 108 is communicated with one end of the second pipeline 105.

[0018] Through the above structural design, the sprayed cleaning liquid finally falls into the liquid receiving disc 106, flows into the cleaning liquid recovery tank 107 from the liquid receiving disc 106, and the water suction pump 108 is opened to assist the cleaning liquid to be drawn from the cleaning liquid recovery tank 107 into the second pipeline 105 and finally flow into the cleaning liquid collecting pool 101 for recycling.

[0019] Preferably, the liquid outlet of the liquid receiving tray 106 or the liquid inlet of the cleaning liquid recovery tank 107 is provided with a filter screen 110. The filter screen 110 is preferably made of a large-pore mesh, for example, a fishing net or window screen that is cut to size. The main function of the filter screen 110 is to filter out larger impurities in the recovered cleaning liquid, such as leaves, willow catkins, plastic bags, etc. Preferably, the liquid outlet of the cleaning liquid recovery tank 107 is provided with a filter 111. The pore size of the filter 111 is not greater than 4 mm. The filter 111 should be easy to clean or replace.

[0020] By the cooperation of the pore sizes of the filter screen 110 and the filter 111, most of the impurities in the recovered cleaning liquid can be filtered out, preventing the recovered cleaning liquid from being blocked by impurities in the pressure pump 102 during reuse, thereby affecting the work efficiency.

[0021] Preferably, the cleaning and spraying device further comprises a mobile trolley 112. The cleaning liquid recovery mechanism is arranged on the mobile trolley 112. Specifically, the cleaning liquid recovery tank 107 is arranged on the mobile trolley 112, and the bottom of the support 109 supporting the liquid receiving tray 106 is also arranged on the mobile trolley. The cleaning liquid recovery mechanism can be conveniently moved by the mobile trolley 112.

[0022] Preferably, the mobile trolley 112 is provided with a liftable supporting plate 113. The cleaning liquid recovery mechanism is arranged on the supporting plate 113. Specifically, the cleaning liquid recovery tank 107 is arranged on the supporting plate 113, and the bottom of the support 109 supporting the liquid receiving tray 106 is also arranged on the supporting plate 113. Specifically, the mobile trolley 112 is provided with a telescopic support 114, which supports the supporting plate 113. The telescopic support 114 is driven to extend or retract by an electric cylinder 115. The telescopic support 114 can be X-shaped to improve stability. The electric cylinder 115 is also arranged on the mobile trolley 112.

[0023] The telescopic support 114 is driven to extend or retract by the telescopic action of the electric cylinder 115, so as to lift or lower the supporting plate 113, thereby adjusting the distance between the supporting plate 113 and the air cooler 201.

[0024] Therefore, according to the characteristics of the air cooler 201 for converter station using a drum fan 202 to take in air from below for forced air cooling, the bowl-shaped wrapping liquid receiving tray 106 is used in cooperation with the lifting operation of the supporting plate 113 to ensure that the liquid receiving tray 106 can completely wrap the air duct of the drum fan 202 and almost all of the sprayed cleaning liquid can be recovered, preventing the cleaning liquid from splashing and leaking, which is more conducive to environmental protection and avoids harming people and equipment around the construction site.

[0025] Preferably, the cleaning and spraying device further comprises a controller 116 arranged on the mobile trolley 112. The controller 116 is connected with the electric cylinder 115 and is used to control the telescopic action of the electric cylinder 115, thereby realizing automatic adjustment of the height of the supporting plate 113.

[0026] Preferably, the bottom of the mobile vehicle 112 is provided with a control box 117. The control box 117 is provided with a battery and a motor. The battery is connected with the controller 116, the electric cylinder 115 and the motor, and is used to provide the required power for these components. The controller 116 is also connected with the motor, and the motor is connected with the rotating shaft of the wheels 118 of the mobile vehicle 112. The controller 116 is used to control the motor to rotate forward or reverse, so as to drive the rotating shaft of the wheels 118 to rotate forward or reverse, so as to drive the wheels 118 to rotate forward or reverse, thereby realizing the forward movement or backward movement of the mobile vehicle 112.

[0027] Preferably, one end of the mobile vehicle 112 is provided with a handle 119, so that the staff can manually move the mobile vehicle 112. The controller 116 can be installed on the handle 119, so as to facilitate the operation of the staff.

[0028] Preferably, the wheels 118 are provided with brake pads, which can be used to brake the wheels 118 during movement, and can also be used to prevent the wheels 118 from slipping when the wheels 118 are stationary.

[0029] From the above description, it can be seen that the mobile vehicle 112 is flexible, adopts an electric power-assisted mode, can move forward or backward, and is used to move the cleaning liquid recovery mechanism, which is more conducive to the cleaning and transfer work of a single fan 202 as a cleaning unit, greatly saves the transfer time, and improves the work efficiency.

[0030] Preferably, the first pipeline 103 is provided with a valve 120 and a flow meter 121. The flow meter 121 is arranged downstream of the valve 120, that is, closer to the spray head 104.

[0031] The flow of the cleaning liquid can be controlled by the different opening degrees of the valve 120, and the flow of the cleaning liquid can be known through the flow meter 121, so that the opening degree of the valve 120 can be adjusted according to the actual situation.

[0032] From the above description, it can be seen that the cleaning and spraying device designed in the above modular manner is simple and convenient to install and disassemble, and a single person can easily complete the installation and disassembly, thereby greatly reducing the number of construction personnel and reducing the construction cost.

[0033] Specifically, the cleaning liquid comprises an aluminum corrosion inhibitor and an alkaline solution. The aluminum corrosion inhibitor comprises the following components in the following weight percentages: sodium alginate 30% to 40%, trisodium silicate 25% to 32%, potassium sodium tartrate 15% to 25%, calcium hydroxide 3% to 8%, aminoacetic acid 5.5% to 13%, and dodecyl phenol polyoxyethylene ether 1% to 3%.

[0034] Preferably, the lower limit of the weight percentage of sodium alginate in the aluminum corrosion inhibitor is 30%, 35% or 36%. The upper limit of the weight percentage of sodium alginate in the aluminum corrosion inhibitor is 35%, 36% or 40%.

[0035] Preferably, the lower limit of the weight percentage of sodium trisilicate in the aluminum corrosion inhibitor is 25%, 28%, 29%, 30% or 31%. The upper limit of the weight percentage of sodium trisilicate in the aluminum corrosion inhibitor is 28%, 29%, 30%, 31% or 32%.

[0036] Preferably, the lower limit of the weight percentage of potassium sodium tartrate in the aluminum corrosion inhibitor is 15%, 20% or 22%. The upper limit of the weight percentage of potassium sodium tartrate in the aluminum corrosion inhibitor is 20%, 22% or 25%.

[0037] Preferably, the lower limit of the weight percentage of calcium hydroxide in the aluminum corrosion inhibitor is 3%, 5% or 5.5%. The upper limit of the weight percentage of calcium hydroxide in the aluminum corrosion inhibitor is 5%, 5.5% or 8%.

[0038] Preferably, the lower limit of the weight percentage of aminoacetic acid in the aluminum corrosion inhibitor is 5.5%, 8% or 10%. The upper limit of the weight percentage of aminoacetic acid in the aluminum corrosion inhibitor is 8%, 10% or 13%.

[0039] Preferably, the lower limit of the weight percentage of dodecyl phenol polyoxyethylene ether in the aluminum corrosion inhibitor is 1%, 1.5% or 2%. The upper limit of the weight percentage of dodecyl phenol polyoxyethylene ether in the aluminum corrosion inhibitor is 1.5%, 2% or 3%.

[0040] More preferably, the corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 35% to 36%, sodium trisilicate 28% to 30%, potassium sodium tartrate 20% to 22%, calcium hydroxide 5% to 5.5%, aminoacetic acid 5.5% to 10%, and dodecyl phenol polyoxyethylene ether 1% to 2%.

[0041] Sodium trisilicate and calcium tartrate play an adsorption role on the surface of aluminum. Aluminum ions on the surface of aluminum have many empty orbits, which can combine with the lone pair electrons of aminoacetic acid to form chelates, which are attached to the metal surface, strengthening the adsorption of sodium trisilicate and calcium ions. In addition, sodium alginate molecules diffuse on the surface of aluminum metal to increase the internal resistance of local corrosion microcells, retard the cathodic reaction, reduce the corrosion current, and thus enhance the corrosion inhibition efficiency. Dodecyl phenol polyoxyethylene ether not only improves the dispersibility and permeability of the corrosion inhibitor in alkaline solution, but also increases the corrosion inhibition performance of sodium trisilicate, calcium tartrate, aminoacetic acid and sodium alginate through competitive adsorption effect, plays a synergistic role, and thus achieves the goal of high corrosion inhibition rate.

[0042] Specifically, the alkaline solution comprises at least one of the following: sodium hydroxide solution and potassium hydroxide solution.

[0043] Specifically, the aluminum corrosion inhibitor is added into 1 mol / L alkaline solution in a proportion of 3-5 g / L and mixed uniformly to prepare the cleaning solution.

[0044] Preferably, the aluminum corrosion inhibitor is added into 1 mol / L alkaline solution in a proportion of 4 g / L and mixed uniformly to prepare the cleaning solution.

[0045] Example 1

[0049] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 35%, sodium trisilicate 28%, potassium sodium tartrate 22%, calcium hydroxide 5.5%, aminoacetic acid 8%, and dodecyl phenol polyoxyethylene ether 1.5%.

[0050] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare the alkaline cleaning solution with aluminum corrosion inhibitor.

[0051] Example 3

[0052] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 36%, sodium trisilicate 29%, potassium sodium tartrate 20%, calcium hydroxide 5%, aminoacetic acid 8%, and dodecyl phenol polyoxyethylene ether 2%.

[0053] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare the alkaline cleaning solution with aluminum corrosion inhibitor.

[0054] Example 4

[0055] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 35%, sodium trisilicate 28%, potassium sodium tartrate 20%, calcium hydroxide 5%, aminoacetic acid 10%, and dodecyl phenol polyoxyethylene ether 2%.

[0056] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare the alkaline cleaning solution with aluminum corrosion inhibitor.

[0057] Example 5

[0058] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 30%, sodium trisilicate 32%, potassium sodium tartrate 25%, calcium hydroxide 3%, aminoacetic acid 8%, and dodecyl phenol polyoxyethylene ether 2%.

[0059] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare an alkaline cleaning solution with the aluminum corrosion inhibitor.

[0060] Example 6

[0061] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 40%, sodium trisilicate 25%, potassium sodium tartrate 15%, calcium hydroxide 8%, aminoacetic acid 10%, and dodecyl phenol polyoxyethylene ether 2%.

[0062] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare an alkaline cleaning solution with the aluminum corrosion inhibitor.

[0063] Example 7

[0064] The aluminum corrosion inhibitor comprises ingredients in the following weight percentages: sodium alginate 30%, sodium trisilicate 31%, potassium sodium tartrate 20%, calcium hydroxide 3%, aminoacetic acid 13%, and dodecyl phenol polyoxyethylene ether 3%.

[0065] The aluminum corrosion inhibitor is added into 1 mol / L sodium hydroxide solution in a proportion of 4 g / L and mixed uniformly to prepare an alkaline cleaning solution with the aluminum corrosion inhibitor.

[0066] Comparative Example

[0067] As a control group, 1 mol / L sodium hydroxide solution is prepared without adding any corrosion inhibitor.

[0068] According to the Test Method for Metal Corrosion Rate and Total Replication Amount in Chemical Cleaning of Industrial Equipment (GB / T 25147-2010), the corrosion amount and corrosion inhibition rate of the aluminum fins are tested. The alkaline cleaning solutions of Examples 1-4 and the comparative example are soaked in the aluminum fins for 24 h at room temperature (about 25°C), and the test results are shown in Table 1. The corrosion inhibition rate is calculated as the difference between the corrosion amount of the comparative example and the corrosion amount of the examples, divided by the corrosion amount of the comparative example.

[0069] Table 1 Experimental data

[0070]

[0071]

[0072] The experimental data of example 1 and example 2 show that simply increasing the mass ratio of sodium alginate and trisodium silicate cannot obviously improve the corrosion inhibition rate, and the appropriate increase of the mass ratio of aminoacetic acid can make the aluminum ions combine with the lone pair electrons of aminoacetic acid to form a chelate, which is attached to the metal surface, and the adsorption of trisodium silicate and calcium ions is strengthened, so that the synergistic effect can be obviously played and the corrosion inhibition rate can be improved. The comparison of the experimental data of example 2, example 3 and example 4 shows that the synergistic corrosion inhibition mechanism of dodecyl phenol polyoxyethylene ether and aminoacetic acid is different, and the proportion of effective corrosion inhibition components and components for synergistic increase needs to be optimized to obtain the best corrosion inhibition effect. The above-mentioned aluminum corrosion inhibitor has a pure aluminum corrosion inhibition rate of 98.8% in a 1 mol / L sodium hydroxide solution at 25 DEG C at a proportion of 4 g / L.

[0073] The cleaning solution is environmentally friendly, low in cost and easy to prepare, the corrosion inhibition performance of the aluminum corrosion inhibitor reaches a pure aluminum corrosion inhibition rate of not less than 98% in a 1 mol / L potassium hydroxide or sodium hydroxide solution at room temperature, and the air cooler can be protected while cleaning.

[0074] In summary, the air cooler cleaning and spraying device for converter station in the embodiment of the present application is flexible and convenient to move and easy to operate, a large amount of manpower can be saved, the cleaning work efficiency can be greatly improved, the cleaning time can be shortened, cleaning liquid leakage can be reduced, the recovered cleaning liquid can be reused due to the filtering effect on impurities, a large amount of cleaning liquid can be saved, the number of times of supplementing cleaning liquid during shutdown can be reduced, the cleaning efficiency is further improved, the lean maintenance of the converter station is accelerated, and the construction cost of the construction enterprise is saved.

[0075] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
