Abstract

The utility model relates to a sludge digesting device for a vertical pipe bundle, which is composed of a pool body, a sludge discharge pipe, a bracket, a vertical pipe bundle, a supernatant liquid outlet pipe, an overflow pipe, a marsh gas output pipe, an upper cover body and a sludge inlet pipe. The utility model is characterized in that the bracket is positioned in the pool body and is connected with the lower pool wall, the vertical pipe bundle is positioned in the pool body, and the lower end surface of the vertical pipe bundle is connected with the bracket. Because the device is provided with the vertical pipe bundle in the pool body, the reaction condition is altered, the disturbance flow shearing generated by the sludge when the marsh gas passes through the pipe bundle is strong, the device accelerates the anaerobic reaction rate and efficiency of the digesting pool, the treatment efficiency is much larger than that of the general sludge digesting pool, the time of the sludge in the digesting pool is shortened and the capital expenditure is saved.

Description

Vertical Restrain Sludge Digestion Device

The utility model is to belong to Sludge Digestion equipment.

The present sludge digestion tank of using, its main drawback is that speed of reaction is slow, reaction efficiency is low; The major cause that causes the problems referred to above is that the rate of mass transfer in the used sludge digestion tank is low excessively, becomes the principal element that restricts its digestion reaction.Because mud overstand in equipment just needs the volume in pond big, floor space is too much, makes its capital construction cost too high, and general mud all need stop 25-30 days in digester.

The purpose of this utility model is to propose a kind of Vertical Restrain Sludge Digestion Device.In the body of pond, set up vertical tube bank, be higher than conventional sludge digestion tank far away at the unit time biogas output, biogas causes that by each root tubular channel of vertical tube bank is upwards mobile the mud turbulent shear is bigger, the intensity of turbulent flow micro-vortex is bigger, ratio is higher, the speed of accelerate sludge digestion reaction and efficient.

The utility model by pond body 1, shore pipe 2, carriage 3, vertically restrain 4, supernatant liquor vent pipe 5, upflow tube 6, biogas output tube 7, upper cover body 8, advance mud pipe 9 and form, as shown in Figure 1; It is characterized in that: carriage 3 is positioned at pond body 1, and connects with the bottom pool wall, vertically restrains 4 and is positioned at pond body 1, and its lower surface and carriage 3 join.Wherein, said vertical tube bank 4 can be one deck, and which floor also can be.

Work reason of the present utility model: pond of the present utility model body 1 connects and composes with upper cover body 8, its inside can be divided into several districts: be ripe sludge district I between the bottom of carriage 3 and pond body 1, place, vertical tube bank 4 places above the carriage 3 is sludge digestion reaction zone II, the top place of vertical tube bank 4 is into mud and supernatant liquid zone III, is methane accumulation district IV between the above and lid 8 of liquid level.Mud enters advancing among mud and the supernatant liquid zone III above the vertical tube bank 4 by advancing mud pipe 9, stirred by the intrafascicular effusive biogas of vertical duct, flow into digestion reaction district II then downwards, in vertical each passage of tube bank, carry out digestion reaction, reacted mud flows into ripe sludge I district downwards along tube bank, the III of the flowing to waterborne district that produces in the reaction is discharged by supernatant liquor vent pipe 5; The biogas that produces in the reaction rises to methane accumulation district IV, flows into the biogas basin by biogas vent pipe 7, and ripe sludge is discharged by the bottom shore pipe 2 of pond body 1.When liquid level was too high in the reaction tank, water and mud were discharged by upflow tube 6, avoid the fail in compression of digester body.

The utility model compared with prior art has following advantage:

1, the diameter of vertically restraining 4 each tubular channel is much smaller than traditional digester body diameter, when its during by same biogas amount in the vertical duct beam passage mud turbulent perturbation with shear much larger than the traditional sludge digester.So just produced at high proportion in the passage in tube bank, high-intensity micro-vortex, their centrifugal inertia has increased the speed that the anerobe biochemical metabolite is removed around it widely, has also increased the speed for the treatment of that biochemical material replenishes to anerobe widely.

2, the surface of vertically restraining 4 tubular channel is biological attachment surface, cover with the anerobe microbial film above, increased biophasic quantity on the one hand widely, increased the contact surface of biophase and mud on the other hand widely, and turbulent shear is strong in the tube bank passage, these biomembranous thin thickness, the rate of mass transfer height, biological activity is good.

3, because after setting up vertical tube bank 4, speed of reaction increases greatly, therefore the unit time biogas output increases greatly, this has just increased the flow velocity of biogas by vertical tube bank 4 greatly, strengthens mud disturbance and turbulent shear in the tube bank, has just more quickened the anaerobic biological metabolite and has removed from anerobe, treat that biological replenishes to the anerobe place, further improve biochemical reaction rate and reaction efficiency, reduce mud residence time in digester, dwindle digester volume and initial cost.

Embodiment of the present utility model:

The utility model by pond body 1, shore pipe 2, carriage 3, vertically restrain 4, supernatant liquor vent pipe 5, upflow tube 6, biogas output tube 7, upper cover body 8, advance mud pipe 9 and form, as shown in Figure 1; Wherein pond body 1, shore pipe 2, supernatant liquor vent pipe 5, upflow tube 6, biogas output tube 7, upper cover body 8,, advance mud pipe 9 and can be and select part for use; Vertical tube bank 4 is made of plastic, and its cross section is cellular, perhaps restrains by many pipes, square tube and forms, and can make the tube bank of different lengths as required, can be one deck during use, but also which floor, as Fig. 4.Carriage 3 usefulness stainless steels, mould and make grid type firmly.

With shore pipe 2, supernatant liquor vent pipe 5, advance mud pipe 9 and connect with the bottom of pond body 1, top respectively and communicate; Upflow tube 6, biogas output tube 7 communicate with upper cover body 8 connections.Carriage 3 places in the pond body 1, and connects with its underpart pool wall, vertically restrains above 4 carriages 3 that place in the pond body 1, and the sealing that is connected and fixed of the upper end of upper cover body 8 and pond body 1 can be used.
