Description

External filter system for air distribution and water collection

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to an air distribution and water collection external filter system.

Background

The double-layer filter bricks are widely applied to a filter system and are used for supporting a filter material layer, collecting filtered water and gas-water backflushing water and gas distribution. The modern filter tank adopts a gas-water backflushing technology to clean the filter material, and the gas-water backflushing process needs uniform water distribution and uniform gas distribution of double-layer filter bricks so as to achieve uniform cleaning of the filter material of the whole tank without dead angles.

The double-layer filter bricks are arranged at the bottom of the deep bed filter tank and the high-efficiency air-water back flushing filter tank, a water collecting tank is arranged below the filter bricks at the bottom of the filter tank, an air distribution manifold is arranged in the filter tank, the water distribution and air distribution of the air-water back flushing process of the filter tank system are realized, and the combination mode of the water collecting tank and the air distribution manifold is as follows:

the air distribution manifold is arranged in the water collecting tank, the bottom of the filter tank is provided with a sunk water collecting tank along the width direction of the filter tank below the double-layer filter bricks through secondary pouring of a concrete cushion layer, an air pipe main pipe is embedded in the concrete cushion layer and extends into the water collecting tank, the air distribution manifold is arranged in the water collecting tank, the air distribution manifold main pipe is in butt joint connection with the embedded air pipe main pipe through a flange, and the air distribution manifold branch pipe is inserted into the inner cavity of the double-layer filter bricks from the bottom of the main pipe in an ascending manner. The gas distribution manifold arranged in the water collecting tank comprises a main pipe, branch pipes, blind plates and the like, and the material is not lower than stainless steel 304. The distribution manifold is fixedly arranged in the water collecting tank, occupies the inner volume of the water collecting tank, and needs to be properly increased in width or depth in order to meet the lower flow velocity of water flow. The gas distribution manifold is arranged in the water collecting tank and is in non-contact with the filter material, the filter material cannot abrade the gas distribution manifold, and the service life of the gas distribution manifold is longer. However, the installation of the gas distribution manifold in the water collecting tank has some problems, the gas distribution manifold is installed in the water collecting tank, the gas tightness or other faults cannot be expressed in the installation process, after the double-layer filter bricks are required to be fixedly installed, whether the gas distribution manifold has faults or not can be reflected through a gas-water back flushing test, and if the faults occur, the double-layer filter bricks which are fixedly installed are required to be stripped out, so that the gas distribution manifold can be repaired or adjusted; after the pebble supporting layer and the filter material layer are installed, the loss of water head in the tank is increased along with the increase of water level in the tank, the thickness of an air bag in the double-layer filter brick is changed when air and water are backflushed, the unsuitable air distribution manifold can show faults, and the air distribution manifold in the water collecting tank can be repaired or adjusted only by pulling the filter material layer, the pebble supporting layer and the fixed double-layer filter brick.

A gas distribution manifold is arranged at the top of the double-layer filter brick above the water collecting tank, the gas distribution manifold is arranged at the top of the double-layer filter brick, the main pipe is horizontally arranged above the double-layer filter brick, each branch pipe is downwards inserted into the inner cavity of the filter brick from the bottom of the main pipe, and the gas distribution manifold comprises the main pipe and the branch pipes embedded in the filter material layer. In the air-water test process, if the air distribution manifold fails, the air distribution manifold can be repaired without pulling open double-layer filter bricks; the gas-water test meets the test requirement, the pebble supporting layer and the filter material layer are arranged above the double-layer filter brick, and if the gas-water backflushing process fails, the gas-water backflushing process can repair the gas-distribution manifold only by pulling the filter material layer open. However, the gas distribution manifold embedded in the filter material layer is rubbed by the filter material, and the service life of the gas distribution manifold is shortened.

The double-layer filter brick has two modes of bottom water inlet and side water inlet; there are three modes of bottom air intake, top air intake and side air intake. The water collecting tank is arranged below the double-layer filter bricks of the conventional deep bed filter system and the high-efficiency air-water backwashing filter system, and is a specific application of water inlet at the bottom of the double-layer filter bricks. If the double-layer filter bricks adopt side water inlet and side air inlet, the bottom of the filter tank does not need to be provided with a water collecting tank, so that the depth of the filter tank can be reduced, and the civil engineering can be saved. The side water inlet and the side air inlet are needed to be provided with a water collecting device and a gas distribution manifold outside the filter tank.

The small-sized integrated filter system adopts a steel structure tank body, a water collecting tank is arranged below the double-layer filter bricks, the depth of the filter is deepened, and the processing difficulty is increased. Therefore, how to design an external water collecting device and a tank body external air distribution manifold device is a problem to be solved when a double-layer filter brick is arranged as an air distribution and distribution system in a small integrated filter tank system.
