The special impurity remover produced by the company's lithium bromide solution is mainly used to remove impurities and purify the lithium bromide solution during the operation of the lithium bromide absorption refrigerator unit.
●Non-stop filter design can purify the lithium bromide solution in the machine without affecting the use of the unit.
●Unique design can make the lithium bromide solution be purified under vacuum environment, which can effectively prevent the lithium bromide solution from contacting the air with adverse effects.
●Unique filter element structure and back-blow design make the filter element longer life and lower operating cost.
●Specially designed special filter element for impurities generated during the operation of lithium bromide solution to ensure the filtering effect.
●The main material is made of 304 stainless steel, which guarantees longer service life than lithium bromide refrigerator.
●The valve uses a special valve to ensure air tightness.
●The connection adopts copper tube plus high vacuum rubber tube combination for more flexible connection.
●Adding auxiliary accessories can be purified under shutdown conditions.
◆This product can be used for new solution filling
3. usage notice
3.1 When you receive the product, please confirm that the product is consistent with the customized product, and whether it is damaged during transportation;
3.2 In order for you to use this product more safely and effectively, please read this manual carefully before use in order to use the impurity remover correctly.
3.3 Before installing and disassembling this product, please close the valve on the unit body and flatten the impurity remover;
3.4 Use special joints or vacuum rubber hoses to connect this product to the unit. For the connection method, see Annex 1.
4. Installation steps
a、First place the impurity remover on the flat and solid ground near the unit;
b、Find the corresponding interface valve according to the installation and piping in Appendix 1.
c、Connect the vacuum cleaner with the vacuum cleaner tube to the unit as shown in Appendix 1.
Vacuum the cleaner
a、Make sure to close the unit ’s dilute solution liquid valve, unit ’s concentrated solution valve, and open the inlet valve and return valve on the impurity remover to close the blowdown valve, and connect the exhaust valve to the unit ’s vacuum device；
b、Start the vacuum pump and slowly open the exhaust valve for air extraction. When the pressure vacuum gauge shows a value or close to -0.1MPa, close the exhaust valve, and then hold the pressure for one hour. If the vacuum does not rebound, it is considered a vacuum.
c、Vacuum bounce occurs Check whether there is leakage between the piping and the flange of the de-ionizer body. After the treatment, follow the above steps until the vacuum is qualified.
4.2 Deduster filtering operation
a、First / close all valves before opening the unit dilute solution liquid valve, the unit concentrated solution valve and the return valve
b、Open the inlet valve slowly, and the opening degree is subject to no significant impact on the normal cycle of the unit
c、Record the date of use after stable operation to determine backwashing and blowdown.
4.3 Backwash sewage operation
a、After 7 days of operation, close the inlet and outlet valves；
b、Open the drain valve；
c、Connect nitrogen to the backflush valve and slowly open the backflush valve for backflushing;
d、When the solution corrosion at the outlet of the blowdown valve becomes smaller, close the recoil valve and blowdown valve at the same time;
e、Follow steps 4.1 and 4.2.
5.1 Pay attention to air tightness when using this product
5.2 Please pay attention to wear protective gloves and protective glasses to prevent the lithium bromide solution from splashing and causing physical injury. The lithium bromide solution accidentally gets into the eyes and rinse with plenty of water.
5.3 Please strictly follow this instruction during operation. Please contact our company when replacing accessories.
5.4 When transporting this product, it should be fixed and stable and then mechanically transported.
