Description

The reverse osmosis membrane off-line cleans and test integrated device

Technical field

The utility model relates to a kind of integration apparatus that contaminated reverse osmosis membrane is cleaned and tests.

Background technology

Development is very fast surplus the reverse osmosis membrane technology nearest ten year, and a lot of large-scale reusing sewage systems all use reverse osmosis membrane technology.Because the sewage complicated component contains each pollutant, so reverse osmosis membrane after use after a while, need clean.In order to guarantee the normal operation of equipment, reverse osmosis membrane must detect after cleaning, up to standard after, can use.But existing cleaning equipment and testing arrangement be independent design separately, uses respectively in the occasion of cleaning and testing.In today of industrial development, be all to require knockdown cleaning and testing arrangement on efficient or the usefulness, both solved the cleaning problem of on-the-spot pollution reverse osmosis membrane, can test out the pollution situation of reverse osmosis membrane simultaneously.Existing testing arrangement also exists: 1. test macro can only be adorned a reverse-osmosis membrane element, so can only test a reverse osmosis membrane at every turn, efficient is low.2. do not possess the temperature adjustment condition, the reverse osmosis membrane test need be carried out under the condition of fixing temperature and salt content, and test must the control water temperature.3. equipment is fixed, and can not move, so can not test according to actual conditions.Existing cleaning device also exists: 1. owing to can not move, can not satisfy client's actual demand, landed cost is high; 2. many putamina combinations are cleaned but can not separate putamina, and cleaning and immersion can not be carried out simultaneously; 3. because the sewage complicated component contains each pollutant, not simply just can satisfy cleaning condition in cleaning process, often need the variation of temperature, PH, flow and single-direction and dual-direction cleaning or the like can solve the cleaning problem with the certain cleaning agent.System's design can not two-wayly be cleaned; If 4. meet difficult situation of cleaning, need to improve cleaning performance, and existing apparatus does not possess heating function through the heating that heats up.

Summary of the invention

The purpose of the utility model provides a kind of reverse osmosis membrane off-line and cleans and test integrated device; Solved the user scene depend merely on a kind of equipment can't be to the complete decision problem of reverse osmosis membrane, simultaneously equipment integrated can solve transportation, operate, deposit, a series of problems such as management.

The technical scheme that the utility model adopts is: the reverse osmosis membrane off-line cleans and test integrated device: the rack-mounted two ends of purging system and test macro.

Described purging system is: electric heating water tank is connected with pump through pipeline; Pump is connected with filter through pipeline; Filter is connected with water inlet manifold, is connected two groups of putamina groups with some valves through arm between water inlet manifold and the return pipe, and every group of putamina group is made up of some cleaning putaminas; Each two ends of cleaning putamina is provided with electric butterfly valve, and return pipe is connected with electric heating water tank.

Described test macro is: supply-water pump is connected with grade one filter; Grade one filter is connected with secondary filter; Secondary filter is connected with high-pressure pump, and high-pressure pump links to each other through the arrival end of each test putamina that pressure piping assembly and high-pressure control valve and plurality of parallel are arranged, and the end of the drainage pipeline that links to each other with the port of export of test putamina effluxes mouth for producing water; One end of pressure piping assembly is provided with the High-Pressure Water adjustable valve, and the former water system of electrical heating is connected with grade one filter.

The beneficial effect of the utility model is: the utility model purging system adopts two-way cleaning, and immersion and cleaning can be carried out simultaneously, and have heating function, are applicable to the cleaning requirement under the various contaminated situation of reverse osmosis membrane.Test macro applicable to any water quality, for equipment provides test safety qualified water source, even under the situation of coming the water condition difference, also can guarantee the safety of reverse osmosis membrane because two-stage filter is set.The former water system major control of electrical heating probe temperature condition can also guarantee not damage the test reverse osmosis membrane through the oxygenate content in the former water system dosing control of the electrical heating water simultaneously.The utility model cleans off-line with test height integrated, solved the user scene depend merely on a kind of equipment can't be to the complete decision problem of reverse osmosis membrane, a series of problems such as while equipment integrated can solve transportation, operates, deposits, management.

The specific embodiment

As shown in Figure 1, the reverse osmosis membrane off-line cleans and test integrated device: purging system (1) and test macro (2) are installed in the two ends on the frame (3).

Described purging system (1) is: electric heating water tank (4) is connected with pump (5) through pipeline; Pump (5) is connected with filter (6) through pipeline; Filter (6) is connected with water inlet manifold (7); Be connected two groups of putamina groups through arm (9) with some valves (10) between water inlet manifold (7) and the return pipe (8); Every group of putamina group is made up of some cleaning putaminas (11), and each two ends of cleaning putamina (11) is provided with electric butterfly valve (12), and return pipe (8) is connected with electric heating water tank (4).

Described test macro (2) is: supply-water pump (13) is connected with grade one filter (14); Grade one filter (14) is connected with secondary filter (15); Secondary filter (15) is connected with high-pressure pump (16); High-pressure pump (16) links to each other through the arrival end of each test putamina (19) that pressure piping assembly (17) and high-pressure control valve (18) and plurality of parallel are arranged; The end of the drainage pipeline (20) that links to each other with the port of export of test putamina (19) effluxes mouthful (21) for producing water, and an end of pressure piping assembly (17) is provided with High-Pressure Water adjustable valve (22), and the former water system of electrical heating (23) is connected with grade one filter (14).
