Abstract
The utility model discloses a floating raft type contact biochemical oxidation tower, which belongs to a sewage treating apparatus, the utility model solves the technical problem that the floating raft type contact biochemical oxidation tower is designed and a support frame and a tower body have strong corrosion resistance and long service life. The utility model has the technical scheme that the floating raft type contact biochemical oxidation tower comprises the tower body, the support frame and filler in the tower body. The utility model is characterized in that the support frame is composed of plates and tubes which are and penetrated in plates holes mutually in parallel, and the tubes are fixed with the plates which are uniformly distributed horizontally. The lengths of the plates and the tubes are smaller than the inner diameter of the tower body, at least three anchor ropes are respectively connected with supporting frame plates which are distributed vertically, the lower ends of the anchor ropes are connected with a convex plate of the bottom of the tower body and the upper ends of the anchor ropes are connected with the tower body through penetrating through a tower top. The utility model can be used for the treatment of organic sewage in the process of chemical fiber production.
Description
Technical field:
The utility model relates to a kind of chemical fibre production waste treatment facility, particularly a kind of floating raft type contact biochemical oxidation tower.
Background technology:
Produce a large amount of organic waste water in the chemical fibre production process, because the organic contamination of waste water needs outwards discharging after the biochemical oxidation tower is handled, otherwise can cause environmental pollution.Existing biochemical oxidation tower its biochemical oxidation process in handling waste water is feasible.Because organic waste water has stronger corrosive nature to ferrous metal, the volume of this biochemical oxidation tower body generally has the many M of 300-1000 more greatly
3, tower body is that steel are made, in addition, have mass filler to fix in the tower body, the tower domestic demand is provided with the fixedly metal supporting frames of filler, and this bracing frame directly is welded on the tower body, form many dead angles on the tower body, be difficult to carry out rotproofing, the bracing frame and the tower body of this tower easily are corroded, cause the damage tower to fall, because bracing frame and packing density are big, no operating space can't be overhauled, tower falls behind and must thoroughly remove and renewal support and filler, and replacement charge is very big.
Summary of the invention:
The utility model technical issues that need to address are a kind of biochemical oxidation towers of design, and its bracing frame and tower body resistance to corrosion are strong, long service life.The technical solution of the utility model is, a kind of floating raft type contact biochemical oxidation tower, it comprises tower body and interior filler and bracing frame thereof, it is characterized in that: bracing frame is made up of the level uniform plate and uniform being through in the plate hole and with the pipe that plate fixes that be parallel to each other, the length of plate and pipe is less than the internal diameter of tower body, have at least three anchor lines to be connected with the vertical support frame plates that distributes in above-mentioned edge respectively, its lower end is connected with the flange of tower body bottom, and the upper end is passed cat head and is connected with tower body.The utility model is because the filler bracing frame that adopts the proportion plastics lighter than water to make, and filler and bracing frame are the buoyant raft structure, be fixed in the tower body with anchor line, buoyant raft and tower body inwall do not have connection, thereby the utility model has compared with the prior art corrosion-resistant coating and advantage easy to maintenance are set easily.
Description of drawings:
Fig. 1 is a longitudinal diagram of the present utility model, and Fig. 2 is the B-B sectional view of Fig. 1.Fig. 3 is the partial enlarged drawing of Fig. 1.
Embodiment:
In conjunction with above-mentioned accompanying drawing the utility model is described in detail, the bottom of tower body 1 is provided with sewage water inlet pipe 8, the both sides on top are provided with blowdown water outlet 5, vertically be evenly equipped with 4 floating raft type bracing frames in the tower, this bracing frame is made up of level uniform 10 the PVC plastic plates 2 and 7 the uniform PVC plastics tubings 4 that are parallel to each other, plastics tubing 4 is welded on respectively in the hole of plastic plate 2, the length of plate and pipe is less than the length of its place tower body plane circular diameter or string, the bracing frame of composition is not contacted with the tower body inwall in tower, and filler 3 is fixed on each bracing frame.Because plate, the pipe of bracing frame are plastic component, the ratio weight average of the whole bracing frame and the filler thereon that distributes is light than water, can be upwards floating, thereby need bracing frame to be resembled on the flange hole that is fixed on the stationary boat on the tower bottom with 4 anchor lines 6, this filler can make its sinking through the dirt on it after the sewage disposal, the upper end of anchor line is passed cat head and is fixed on the tower body, and buoyant raft and filler are fixed on the runner certain in the tower.The bracing frame of this structure does not contact with the tower body inwall, and inner wall of tower is slick disc, thereby the preserving timber bed of material 9 can be set on inner wall of tower, as frp layer.The work-ing life of this biochemical tower is longer, and when maintenance maybe needed to change bracing frame and filler, the serviceman entered Ta Nei by manhole 7 and can keep in repair easily.
Claims (1)
1. a floating raft type contacts the biochemical oxidation tower, it comprises tower body and interior filler and bracing frame thereof, it is characterized in that: bracing frame is made up of the level uniform plate and uniform being through in the plate hole and with the pipe that plate fixes that be parallel to each other, the length of plate and pipe is less than the internal diameter of tower body, have at least three anchor lines to be connected with the vertical support frame plates that distributes in above-mentioned edge respectively, its lower end is connected with the flange of tower body bottom, and the upper end is passed cat head and is connected with tower body.
