Technical Field

The invention relates to the technical field of water purification, in particular to a carbon-sandwiched activated carbon filter element and a filtering method.

Background

The development of water purifier is towards the direction of miniaturization and integration, therefore filter core and the high compactness of overall arrangement and the integration in the water purifier, and under this condition, in order to make full use of space, rearmounted active carbon filter core probably produces the space not enough, or the diameter is big but the condition of active carbon layer height, and according to traditional filtration mode filtration route short, produce under the large-traffic easy channeling and blind spot, filtration efficiency descends.

Disclosure of Invention

The invention aims to provide a carbon-sandwiched activated carbon filter element and a filtering method. The invention can effectively reduce pressure drop and improve filtering efficiency.

The technical scheme of the invention is as follows: a carbon-sandwiched activated carbon filter element comprises a filter part, wherein the filter part comprises an outer ring carbon rod, granular activated carbon and a water outlet channel which are sequentially arranged from outside to inside;

the filter unit further comprises a first end cover and a second end cover which are respectively arranged at two ends of the filter part in a sealing manner, and a water outlet communicated with the water outlet channel is formed in the first end cover or the second end cover.

In the carbon-sandwiched activated carbon filter element, the water outlet channel is formed by the hollow inner ring carbon rod, and the hollow part of the inner ring carbon rod is communicated with the water outlet.

In the carbon-sandwiched activated carbon filter element, the water outlet channel is formed by a hollow water outlet collecting pipe, and the hollow part of the water outlet collecting pipe is communicated with the water outlet.

According to the filtering method of the carbon-sandwiched activated carbon filter element, inlet water radially enters the filtering part from the outer ring carbon rod, enters the water outlet channel after passing through the outer ring carbon rod and the granular activated carbon of the filtering part, and then flows out from the water outlet.

According to the filtering method of the carbon-sandwiched activated carbon filter element, when the water outlet channel is formed by the hollow inner ring carbon rod, the particle activated carbon is selected to have a smaller particle size, so that the filtering efficiency is improved.

In the filtering method of the carbon-sandwiched activated carbon filter element, the water outlet channel is formed by the hollow water outlet collecting pipe and is used for reducing the pressure drop of the filter element.

Compared with the prior art, the filter adopts the design of the outer ring carbon rod and the granular activated carbon, the inlet water radially enters the filter part from the outer ring carbon rod, the outer ring carbon rod plays a good water distribution role for the granular carbon in the middle layer, and the inlet water enters the water outlet channel after passing through the outer ring carbon rod and the granular activated carbon of the filter part and then flows out from the water outlet, so that the filter can effectively reduce the pressure drop for filter elements with all carbon rod structures, and the filtering efficiency is improved. Because the pure granular carbon filter element in the filter element needs the shell sleeve to restrain granular carbon, the granular carbon filter element utilizes the outer ring carbon rod and the water outlet channel to play a role in restraining the granular carbon, combines the roles of the first end cover and the second end cover, can improve the space utilization rate, has better density of the outer ring carbon rod, and can contain more active carbon. In addition, when the pressure drop of the filter element is still higher, the water outlet channel can be set as a water outlet collecting pipe, holes are formed on the periphery of the pipe wall of the collecting pipe, and filtered water is radially collected; furthermore, when the water outlet channel is formed by a hollow inner ring carbon rod, the particle activated carbon is selected with a smaller particle size, and the filtering efficiency is further improved. The invention has simple production and processing, can share one set of the first end cover and the second end cover, and saves the cost.

Detailed Description

The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.

Example (b): a carbon-sandwiched activated carbon filter element, as shown in figures 1 and 2. The device comprises a filtering part 1, wherein the filtering part 1 comprises an outer ring carbon rod 2, granular activated carbon 3 and a water outlet channel 4 which are sequentially arranged from outside to inside;

the filter part also comprises a first end cover 5 and a second end cover 6 which are respectively arranged at two ends of the filter part 1 in a sealing way, and a water outlet 7 communicated with the water outlet channel 4 is arranged on the first end cover 5 or the second end cover 6.

In this embodiment, the water outlet channel 4 is formed by a hollow inner ring carbon rod, and the hollow part of the inner ring carbon rod is communicated with the water outlet 7.

Utilize the double-layered carbon activated carbon filter core in this embodiment to filter, the intaking radially gets into filter house 1 from outer lane carbon rod 2, gets into outlet channel 4 behind outer lane carbon rod 2 and the granular activated carbon 3 of filter house 1, flows out from delivery port 7 again. The embodiment adopts the outer ring carbon rod 2 and the inner ring carbon rod, and the middle layer is the design of granular activated carbon 3, so that the pressure drop can be effectively reduced. Because inner circle and outer lane are the carbon rod, have better precision, consequently the particle carbon in intermediate level can choose for use littleer particle diameter, and then promotes filtration efficiency. The outer ring carbon rod 2 plays a good water distribution role for the middle layer granular carbon; the filter element is simple to produce, and can share one upper end cover and one lower end cover. Because the density of the carbon rod is better, more active carbon can be contained, and meanwhile, the pure granular carbon filter element needs the shell sleeve to restrain granular carbon, the granular carbon filter element utilizes the outer ring carbon rod 2 and the inner ring carbon rod to play a role in restraining the granular carbon, and the space utilization rate is improved.

In another embodiment, the water outlet channel 4 is formed by a hollow water outlet collecting pipe, holes are formed on the periphery of the pipe wall of the water outlet collecting pipe, and filtered water is radially collected; the hollow part of the water outlet collecting pipe is communicated with the water outlet 7. The mode can deal with the condition that the pressure drop of the filter element is higher, and can further effectively reduce the pressure drop.
