Abstract

The utility model relates to a water distributing and backwashing device for active carbon adsorption equipment. The water distributing and backwashing device comprises barrel body equipment, wherein the barrel body equipment is arranged at the periphery of the water distributing and backwashing device, and water distributing devices are respectively arranged at the upper part and the lower part of the inner part of the barrel body equipment, so that water can be uniformly distributed and received when water is charged in case of operation of the equipment and is discharged in case of backwashing. Active carbon particles have a larger specific gravity than water and cannot afford to the impact during the backwashing, and carbon can be removed in case no water sucking device and backwashing device exists. The water distributing and backwashing device mainly consists of a primary pipe, a secondary pipe, a branch pipe and a water filtering cap; and as the water filtering cap is provided, the problem of the leakage of carbon is solved, adsorption function is effectively ensured, and a favorable condition is provided for the treatment of high-purity water.

Description

Charcoal absorption equipment water distribution and backwash device

[technical field]

The utility model relates to a kind of device, specifically is a kind of absorption and filtering water distribution and backwash device.

[background technology]

Charcoal absorption equipment on the existing market generally adopts: arch bar boring.The sand grains of place mat grating size is directly made bed course respectively above, places the charcoal absorption material above, and charcoal layer top adds high spatial in case walk charcoal, leakage charcoal; But, leak sand, walk charcoal, leak charcoal with regard to as easy as rolling off a log bed course after the backwash through the operation of repeated multiple times; Level equipment after the leakage charcoal arrives easily during operation is walked charcoal easily during backwash, make the high decline of adsorption layer, poor water mass after filtering.

[utility model content]

The purpose of the technology of the utility model is for solving above-mentioned existing problem, and a kind of novel filtration water distribution and backwash device are provided.

For addressing the above problem, the charcoal absorption equipment that the utility model Fig. 2 is provided is received water and backwash device, owing to be provided with the filtered water cap, therefore when operation and backwash, has prevented the leakage charcoal effectively, has walked charcoal phenomenon and filter back water purification degree.

The useful technique effect of the utility model: receive water and backwash device and be arranged at upper and lower in the cylindrical shell equipment respectively, water distribution is same evenly effectively when receiving water and backwash when mainly playing operation, prevents bias current.

[description of drawings]

Below in conjunction with the embodiment accompanying drawing, the utility model is further described.

The charcoal absorption equipment synoptic diagram that Fig. 1, Fig. 2 generally adopt for the existing market.

Fig. 3, Fig. 4 are that the utility model charcoal absorption equipment is received water and backwash device synoptic diagram.

[embodiment]

Below in conjunction with accompanying drawing the utility model is done further explanation.

Existing charcoal absorption equipment vertical planning drawing 1 is shown in Figure 2 with section; Top water-in 1, shelves water plate (2) in this cylindrical shell equipment (6); There are water outlet (3) and arch bar (4) in the below, and its surface is drilled with the water hole of some amount, places the sand grains of various different diameters from the bottom to top and makes the gac bed course; Any processing is not done in the top in the cylindrical shell equipment (6), just cylindrical shell is suitably increased, and increasing of it is not enough to the impact of the equipment that bears in backwash intensity, makes as easy as rolling off a log leakage sand when moving particularly backwash, runs gac, and filtering layer (5) highly reduces, filtered water water quality variation.

Water-distributing device of the utility model such as vertical planning drawing 3 are shown in Figure 4 with section; Top water-in (1) in cylindrical shell equipment (8); Through each 1 cover is responsible for (3), inferior pipe (4) up and down in the equipment, arm (5) carries out branch distributing water and receives water; And the filling coarse sand is made bed course on the end socket of cylindrical shell equipment (8) below, makes filtering layer (7) the current distributed uniform in entire equipment adsorption filtration cross section, and configurating filtered water cap (6).Because of the sand grains footpath of filtered water cap (6) slit less than the filtering layer top; No matter which kind of situation appears in operation and backwash; Can not leak charcoal and walk the charcoal phenomenon, it is stable both to have guaranteed effectively that filtering layer (7) filters, and can guarantee to filter back water purification degree again for a long time; The more important thing is and prolong backwash cycle, conserve water resource effectively.

Claims

1. charcoal absorption equipment water distribution and backwash device is characterized in that: upper and lower is provided with respectively and receives water and the backwash device is formed in cylindrical shell equipment; And install the filtered water cap additional at device interior.
