Description
Technical field
This utility model belongs to technical field of sewage treatment equipment, is specifically related to a kind of desliming and improves system.
Background technology
In MSBR biochemical wastewater treatment system, desliming system is the most very important operation.In actual production, by
The water yield in sewage is continually changing, and this also causes the treating capacity of system also in constantly change.But the setting of whole system
When meter surplus is less than the change of system throughput, desliming system arises that race mud phenomenon, and in the mud now deviate from, moisture content is relatively
Height, exist can not qualified discharge risk, the mud simultaneously run out of will be discharged to lifting system and be again introduced into again place's science and engineering of Sewage Plant
Skill, causes the waste of electric energy and the increase of operation cost.
Desliming system as in whole biochemical treatment system the most easily occur blocking one section, in running and run after
It is required for carrying out backwash to prevent equipment from blocking.Need during backwash to open backwashing pump, but biochemical treatment system sets
The startup of the backwashing pump of meter and the equal imperfection of closing control systemic-function.Owing to during lectotype selection, many selections peak load is yes
Model, when producing load and being less, i.e. the hydraulic pressure in pipeline is less than water pump operation minimum pressure (0.1MPa) or higher than water pump fortune
During row maximum pressure, (0.6MPa) water pump still may proceed to operating, and hydraulic pressure can cause its machine less than backwashing pump operating during minimum pressure
Envelope is damaged, and pipeline pressure can be caused too high and booster when hydraulic pressure is higher than maximum pressure pump operation, increases maintenance cost and increases simultaneously
Add power consumption, water consumption, finally increase operating cost, have an effect on the properly functioning of Sewage Plant.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of desliming improves system.
This utility model is achieved by the following technical solution:
A kind of desliming improves system, is made up of sludge conveying system, backwashing system and deslimer, described mud conveying
System is driven motor, sludge pump inlet tube, sludge pump outlet to form by sludge pump, sludge pump, and described sludge pump drives electricity
Machine is connected by converter and power distribution cabinet；Described backwashing system is pumped out by the water pump that recoils, back-flushing pump inlet pipe, back-flushing
Mouth pipe composition, described back-flushing pump inlet pipe is provided with pressure transmitter, and described pressure transmitter passes through data wire and control
Molding block carries out data interaction, the startup/stopping of described recoil water pump by described controller according to described pressure transmitter
Feedback signal control；Described sludge pump outlet and back-flushing pump discharge pipe are all communicated to described deslimer.
Described sludge pump inlet tube is provided with Mud-intake valve, and sludge pump outlet is provided with mud valve.
Described back-flushing pump inlet pipe is provided with water intaking valve, and back-flushing pump discharge pipe is provided with outlet valve.
Described pressure transmitter is arranged between described water intaking valve and recoil water pump.
The startup pressure of the recoil water pump that described pressure transmitter sets is as 0.1MPa≤startup pressure≤0.5 MPa.
Compared with prior art, this utility model has the advantages that
(1) this utility model drives at sludge pump increases converter, by the rotating speed of Frequency Converter Control sludge pump on motor
Thus control the conveying capacity of sludge pump so that and the impact of the operation of the system not amount of being subject to processing fluctuation, overcome because of system overload
The phenomenon of " race mud " occurs, improves the efficiency of sewage disposal；
(2) by setting up converter, the control of sludge pump is more convenient, automaticity is higher, simultaneously can be according to need
Seek the rotating speed controlling pump, saved the energy, reduced production cost；
(3) by setting up pressure transmitter before recoil water pump, anti-according to the hydraulic pressure control in back-flushing pump inlet pipe
Startup/the stopping of jet water pump, decreases hydraulic pressure and its machine envelope can be caused to damage less than backwashing pump operating during minimum pressure, and hydraulic pressure is high
Pipeline pressure can be caused too high and the generation of the situations such as booster when maximum pressure pump operation, reduce maintenance cost, improve
Service life of equipment；
(4) this utility model simple in construction, reasonable in design, well compensate for existing in prior art design defect.
