Description
Technical field
The present invention relates to a kind of improvement of recirculated water secondary filter, specifically a kind of heat-engine plant circulating water automatic brushing and wiping type cleaning secondary filter, is applicable to the filtration of seashore heat-engine plant circulating water.
Background technology
At present, school pays much attention to the social practice teaching of student, advocates student and makes a social investigation, excavate innovation subject.In the practice of power plant, know that secondary filter is indispensable parts in condenser of power plant cooling water open-cycle system, be mainly used in the filtration of recirculated water, prevent the dirt in recirculated water from entering condenser.The secondary filter of current use comprises " L " shape cylindrical case, 4 tubular element side by side, 4 sewage draining exits and programmed control electric controlling organization, 4 tubular element are side by side located in the circulating water outlet section of " L " shape cylindrical case, 4 sewage draining exits are located on the sidewall of the recirculated water entrance of " L " shape cylindrical case, and by pipeline and 4 tubular element one_to_one corresponding side by side, during normal water supply, sewage draining exit is closed, recirculated water flows into from the entrance of recirculated water entrance, after 4 tubular element are side by side filtered, flow out from the outlet of circulating water outlet section, dirt in recirculated water is stopped or is sticked to the entrance side of tubular element, reach the object that recirculated water filters.Along with the thickness stopped or adhere to dirt increases, the strainability of tubular element worse and worse, therefore needs backwash.During for one of them tubular element backwash, then close the passage of this tubular element, open corresponding sewage draining exit, water from other three tubular element flows to this tubular element from the negative, wash out the dirt of this tubular element, and discharged by sewage draining exit, realize the object of backwash.The fixed installation of the employing that this tubular element has, the employing also had rotates suction type and installs.The deficiency of current this secondary filter is: one is the dirt owing to washing away attachment by the recoil strength of water, there is no the power of brushing, so cleaning performance is poor, particularly power plant, seashore, recirculated water is seawater, not only mineral contaminants is had in seawater, also has a large amount of organic microbials, these organic microbials, firmly can be adsorbed on the surface of tubular element, flourish, and with mineral contaminants twine be fixed in one, so the recoil strength by water is difficult to the dirt of tubular element to wash away, and is not suitable for the filtration of seashore generating plant circulation-water; Two is owing to all adopting circular tube structure, and cause complex structure, production technology is various, and cost of manufacture is high, installs and uses inconvenience; Three is that automatic control performance is poor.
Known by retrieving, in order to improve backwash effect, existing many reports improved about secondary filter structure, but there is not yet and adopt brushing power, force the report organic microbial of screen surface attachment and mineral contaminants being cleaned, be specially adapted to the secondary filter that seashore generating plant circulation-water filters.
Summary of the invention
The object of the present invention is to provide a kind of cleaning performance that can not only improve secondary filter, and adopt brushing power, force the organic microbial that screen surface adhered to and mineral contaminants to be cleaned, be specially adapted to seashore generating plant circulation-water and filter and structure is simple, easy to install and use, the heat-engine plant circulating water automatic brushing and wiping type cleaning secondary filter being convenient to automatically control.
In order to reach above object, the technical solution adopted in the present invention is: this heat-engine plant circulating water automatic brushing and wiping type cleaning secondary filter, comprise circulating water intake, circulating water outlet, circulating water intake end flanges dish and circulating water outlet end flanges dish, it is characterized in that: between described circulating water intake end flanges dish and circulating water outlet end flanges dish, be welded and fixed square tube, be provided with vertically arranged square filter screen at intraluminal middle part, side, the area of square filter screen is consistent with the intracavity section area of square tube; Be provided with reciprocal bar shaped brush at square filter screen towards the side of circulating water intake, the brush finish of reciprocal bar shaped brush touches the apparent surface of square filter screen, and the length direction of reciprocal bar shaped brush is parallel to the upper wall of square tube, and its length is consistent with the transverse width of square filter screen; The diapire of described square tube is provided with bar shaped funnel-form blowdown tank, and the suitable for reading of bar shaped funnel-form blowdown tank is in the side of square filter screen towards circulating water intake; In the middle part of the upper wall of described square tube, hydraulic cylinder is installed, the piston rod of hydraulic cylinder passes the sealing slide opening of square tube upper wall, the end of its piston rod is fixedly connected with the upper wall of reciprocal bar shaped brush, and the distance of stretch out and draw back of piston rod is advisable with the longitudinal width enabling reciprocal bar shaped brush and brush square filter screen; The end mouth of described bar shaped funnel-form blowdown tank is provided with magnetic valve, and connects blow-off pipe by magnetic valve; The oil pipe line of described hydraulic cylinder connects switching valve, is realized the flexible conversion of hydraulic cylinder piston rod by the oil circuit conversion of switching valve; Described switching valve and magnetic valve by cable linker controller, cyclelog setting at interval of 4 hours hydraulic cylinders piston rod complete a telescopic process, magnetic valve completes switch once in each interval of one day, realizes automatically brushing, cleaning.
The present invention is also implemented by following measure: the port of export of described blow-off pipe connects pulverizer, and pulverizer connects negative pressure pump by pipeline; The entrance of negative pressure pump is provided with filter plug, and negative pressure delivery side of pump accesses square filter screen towards in the square tube of circulating water intake side by feeding back pipe; The pipeline entering negative pressure pump is provided with filter residue and flows out valve.
Four both sides, limit of described square filter screen are provided with quadrangle folder frame, and the section of quadrangle folder frame is towards the right angled triangle of square filter screen, and fix towards the quadrangle folder frame of the side that water flows out and the inwall of square tube.
The area of section size of described square tube is determined according to the diameter of the circulating water pipe of condenser of power plant.
Described sealing slide opening is the metallurgical axle sleeve of oil containing powder, is sleeved on the piston rod of hydraulic cylinder.
Described pulverizer, negative pressure pump, cyclelog, magnetic valve and switching valve are prior art, therefore seldom state.
Beneficial effect of the present invention is: this heat-engine plant circulating water automatic brushing and wiping type cleaning secondary filter, owing to adopting brushing mode, there is the strong power wiped, so the mineral contaminants of organic microbial and the blending that filter screen adsorbs can be cleaned, significantly improve the cleaning performance of filter screen, and structure simple, easy to install and use, be convenient to automatic control.Seashore generating plant circulation-water can be widely used in filter.
