Description

A kind of removable lime stone slurry piping filter

Technical field

The utility model is related to a kind of lime stone slurry piping filters more particularly to one kind to select according to requirements The strainer of different size, strainer disassembling, assembling and replacing are convenient, and discharge can be facilitated to filter out the removable lime stone slurry pipeline mistake of impurity Filter.

Background technology

Lime stone slurry piping filter is mainly used for Limestone-gypsum Wet Flue Gas Desulfurization Process system, and the cyclone of the system is set Standby easily to generate blocking because gypsum slurries particle is excessive, existing method is usually that filtering is installed on cyclone inlet pipeline Device filters out the bulky grain tamper in gypsum slurries by filter device, but existing filter device often exist investment compared with Greatly, the tamper of setting specification can only be often filtered out, and filters out the technical problems such as impurity reset procedure is time-consuming and laborious.

Invention content

The utility model can select the strainer of different size according to requirements mainly there is provided a kind of simple in structure, Strainer disassembling, assembling and replacing is convenient, and discharge can be facilitated to filter out the removable lime stone slurry piping filter of impurity, solves existing Cost of investment present in technology is big, can only often filter out the tamper of setting specification, and filters out the time-consuming expense of impurity reset procedure The technical problem of power etc..

The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：A kind of removable stone Lime stone slurries piping filter, including filter housings and extend through connection the left and right end of filter housings inlet tube and Outlet tube has been horizontally set with prime coarse strainer and rear class refined filtration successively between the inlet tube and outlet tube in corresponding filter head housings body Net, and be equipped with strainer in filter housing top corresponding with prime coarse strainer and rear class refined filtration net and dismount mouth, with prime coarse filtration Net and the corresponding filter housings bottom of rear class refined filtration net are equipped with sewage draining exit.By in filter housings into and out of horizontal between liquid pipe To setting prime coarse strainer and rear class refined filtration net, you can realize secondary filtration by two filter screens, and pass through different strainers To realize the filtering of different-diameter limestone particle；By in prime coarse strainer and the corresponding filter housings top of rear class refined filtration net Portion is arranged strainer and dismounts mouth, is convenient for the disassembling, assembling and replacing of strainer；By being equipped with sewage draining exit in filter housings bottom, you can pass through row Dirty mouth excludes to filter out impurity in time, and impurity reset procedure is time saving and energy saving, with meet it is various under the conditions of filtering remove contamination requirement.

Preferably, being set respectively in filter housings interior sidewall surface corresponding with the prime coarse strainer and rear class refined filtration net There are U-shaped card slot, prime coarse strainer and rear class refined filtration net interworking to be connected in corresponding U-shaped card slot.The left and right sides interworking of strainer It is connected in the corresponding U-shaped card slot of filter housings internal face, fixed form is simple and reliable, sliding dismounting, convenient to disassembly.

Reinforcing rib can be the various shapes such as " well " font, preferably, in the prime coarse strainer and rear class refined filtration net Middle part be respectively equipped with " ten " word reinforcing rib.By the way that " ten " word reinforcing rib is arranged on the surface of strainer, the entirety of strainer can be improved Intensity increases shock resistance and the non-deformability of strainer.

Preferably, one end of the sewage draining exit through connection with corresponding filter housings in the middle part of prime coarse strainer On, the other end through connection on corresponding filter housings in the middle part of rear class refined filtration net, and on the port of sewage draining exit respectively Cover is equipped with blowdown flange plate.When sewage draining exit extends transversely through the bottom of filter housings, you can by sewage draining exit to filter head housings Reversed water filling in vivo rinses out the impurity that filters out for accumulating in filter housings bottom, and flow flushing pollution discharge is convenient and efficient.

Preferably, the inlet tube is the conical pipe being docked on filter housings, the big opening end of inlet tube is right inwardly It is connected on filter housings.Inlet tube before filtering uses outer small interior big conical pipe, makes the slurry stream prompt drop into filter It is low, to reduce the impact to strainer.

Preferably, dismounting flange plate equipped with strainer in strainer dismounting mouth upper cover.Cover is on strainer dismounting mouth Strainer dismount flange plate, it is ensured that filter housings working condition keep it is closed, open strainer dismount flange plate Replace strainer.

Preferably, being equipped with erosion resistant coating on the internal face of the filter housings.Erosion resistant coating improves filter housings Resistance to corrosion extends the service life of filter.

Therefore, a kind of removable lime stone slurry piping filter tool of the utility model has the advantage that：

1, using multistage filtering, the filtering of different-diameter limestone particle is realized by changing strainer；

2, strainer has dress reinforcing rib, increases shock resistance and non-deformability；

3, excessively stream part uses scale anticorrosion, improves the resistance to corrosion of filter；

4, each interface uses flanged joint, dismounting and screen replacing convenient；

5, the inlet tube before filtering uses outer small interior big conical pipe, so that the slurry flow rate into filter is reduced by 50%, subtracts The small impact to strainer；

6, simple in structure, it is easy to grasp, movable part is few, lasts a long time, and investment is smaller.
