Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tubular membranes, in particular to a self-series tubular membrane component cleaning system. Background Art
[0002] Traditional tubular membranes currently on the market are all connected in parallel and are widely used in the food, bioengineering, chemical, and water treatment industries. However, these membranes can experience rapid fouling and short cleaning cycles in certain applications, such as landfill leachate. The high turbulence of self-connected tubular membranes makes them less susceptible to fouling and longer cleaning cycles in applications with highly viscous materials. However, due to the high viscosity of the materials, cleaning must be more frequent.
[0003] The current cleaning method is mainly chemical cleaning. The disadvantages of frequent chemical cleaning are as follows:
[0004] 1) Reduce the life of the membrane;
[0005] 2) High cost of medicine;
[0006] 3) Long downtime.
[0007] This increases the cost of reagents and membrane investment, which is not conducive to the promotion of self-series tubular membrane modules.
[0008] The series structure is suitable for physical cleaning, but the physical cleaning system of the self-series tubular components is generally connected in series with the membrane components. The main problem caused by this physical cleaning is the clogging of the cleaning balls. The clogging is divided into two parts: one is in the equipment, and the other is in the membrane tube. That is, the cleaning balls used are easily clogged in the membrane tube, pump impeller, valve and flow meter. Utility Model Content
[0009] In response to the above problems, the utility model provides a self-series tubular membrane module cleaning system. The cleaning module exists independently of the self-series tubular membrane module in the bypass, and the two do not interfere with each other during operation, which reduces membrane fouling and extends the chemical cleaning cycle, reduces the operating agent cost and extends the membrane life.
[0010] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:
[0011] A self-series tubular membrane module cleaning system comprises a self-series tubular membrane module and a cleaning module, wherein the water inlet of the self-series tubular membrane module is connected to the water inlet pipe, the water inlet pipe is provided with a water inlet pipe valve, the concentrate outlet of the self-series tubular membrane module is connected to the concentrate pipe, the concentrate pipe is provided with a concentrate pipe valve, the cleaning module comprises a cleaning water inlet pipe connected to a water pump, the cleaning water inlet pipe is connected to the water inlet pipe between the water inlet and the water inlet pipe valve via a water inlet side branch pipe, the water inlet side branch pipe is provided with a water inlet side valve A, a cleaning ball placement device A and a water inlet side valve B in sequence, the cleaning inlet The water pipe is connected to the brine pipe between the brine inlet and the brine pipe valve via a brine branch pipe. The brine branch pipe is sequentially equipped with brine valve A, a cleaning ball placement device B, and brine valve B. Cleaning balls are placed in both cleaning ball placement devices A and B. The water inlet pipe between the water inlet and the water inlet valve is connected to a cleaning discharge pipe A, which is equipped with a cleaning discharge valve A. The brine pipe between the brine inlet and the brine pipe valve is connected to a cleaning discharge pipe B, which is equipped with a cleaning discharge valve B. The cleaning assembly, which uses a water pump to pressurize and deliver cleaning balls and the transport medium (clean water), is divided into two parallel sections: the water inlet side and the brine side. These two sections operate sequentially for cleaning, using one to two cleaning balls at a time. One operation of each section constitutes a cleaning cycle.
[0012] Preferably, the cleaning ball is a spherical sponge, which is loose and porous, soft in texture, and can physically scrub and alleviate membrane clogging.
[0013] Preferably, the water inlet pipe valve, the concentrate pipe valve, the water inlet side valve A, the water inlet side valve B, the concentrate side valve A, the concentrate side valve B, the cleaning discharge valve A and the cleaning discharge valve B are pneumatic diaphragm valves.
[0014] Preferably, the number of the self-series tubular membrane modules is at least two and they are arranged in parallel. The number of the inlet-side branch pipes and the concentrate-side branch pipes corresponds to the number of the self-series tubular membrane modules and they are arranged in parallel. The cleaning ball placement device A and the inlet-side valve B, as well as the cleaning ball placement device B and the concentrate-side valve B, respectively correspond to the self-series tubular membrane modules. Only one inlet-side valve A and one concentrate-side valve A may be provided on the combined inlet-side branch pipe and concentrate-side branch pipe before parallel connection.
[0015] The advantages of the present invention are: 1. The cleaning component in the present invention exists in the bypass independently of the self-series tubular membrane component, and their operation does not interfere with each other. The use of an independent bypass cleaning system (the cleaning ball is only in the membrane tube) avoids the problem of cleaning ball clogging in the equipment (such as the pump impeller, valve and flow meter, etc.).
[0016] 2. Slow down the fouling of the membrane and extend the chemical cleaning cycle, reduce the damage of chemical cleaning agents and the cost of operating agents, and extend the life of the membrane.
[0017] 3. The independent cleaning component reduces the blockage of the membrane tube due to the cleaning ball. The cleaning ball placement device adopts a stepped structure to ensure that only one cleaning ball passes through at a time. BRIEF DESCRIPTION OF THE DRAWINGS
