Abstract
The utility model relates to a duplex filter device, which is characterized by comprising a feeding three-way valve, a discharging three-way valve and two filters, wherein the filter consists of a filter cylinder and a filter element; the filter element is arranged at the upper part inside the filter cylinder; a feeding pipe and a discharging pipe are respectively arranged at the upper part and the lower part of the filter cylinder; the feeding three-way valve is connected with the feeding pipes of the two filters; and the discharging three-way valve is connected with the discharging pipes of the two filters. With the adoption of the duplex filter device, the two parallel filters are alternatively used, one filter is in a use state and the other filter is in a standby state, so that the condition that the running of a desulphurizing and denitrifying device is stopped caused by that the duplex filter device is blocked, the continuous running of the desulphurizing and denitrifying device is guaranteed and the environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of industrial flue gas cleaning equipment, especially relates to a kind of dual filter system, and the ammoniacal liquor that is used for desulphurization denitration equipment filters.
Background technology
In the desulfurizing industrial fume denitrification process, need a large amount of ammoniacal liquor that use; At present in this kind equipment; The filter of ammoniacal liquor adopts single filter mostly, when problems such as filter generation obstruction need be overhauled, needs to suspend the operation of desulphurization denitration equipment; Thereby cause the industrial smoke directly discharging between turn(a)round without desulphurization denitration, cause atmosphere pollution to a certain extent.
The utility model content
The applicant has carried out research and has improved to above-mentioned problem, and a kind of dual filter system is provided, and avoids suspending because of obstruction the operation of desulphurization denitration equipment, guarantees the continuous service of desulphurization denitration equipment, reduces the pollution to environment.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of dual filter system; Comprise charging triple valve, discharging triple valve and two filters; Said filter is made up of filter cylinder and filter core, and said filter core is arranged on the top in the said filter cylinder, and the top of said filter cylinder and bottom are respectively equipped with feed pipe and discharge nozzle; Said charging triple valve connects the feed pipe of two filters, and said discharging triple valve connects the discharge nozzle of two filters.
Further:
Said filter cylinder is connected and composed by cylindrical shell, top cover, bottom, and the upper end of said filter core connects said top cover, and said bottom is provided with scavenge port.
The technique effect of the utility model is:
The disclosed a kind of dual filter system of the utility model utilizes the filter of two parallel connections, and one is in user mode; One is in stand-by state, uses by turns, avoids suspending because of obstruction the operation of desulphurization denitration equipment; Guarantee the continuous service of desulphurization denitration equipment, reduce pollution environment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Like Fig. 1, shown in 2, the utility model comprises charging triple valve 1, discharging triple valve 2 and two filters 3, and charging triple valve 1 is provided with up and down with discharging triple valve 2, and two filters 3 are arranged on the both sides of charging triple valve 1 and discharging triple valve 2.Filter 3 is made up of filter cylinder 300 and 302 of filter cores; Filter cylinder 300 is connected and composed through flange by cylindrical shell 303, top cover 301, bottom 304; The upper end of filter core 302 connects top cover 301, and bottom 304 is provided with scavenge port 305, can be from the hydrops the scavenge port 305 discharge filter cylinders 300 during maintenance.Filter core 302 is positioned at the top of filter cylinder 300; The top of the cylindrical shell 303 of filter cylinder 300 and bottom are respectively equipped with feed pipe 306 and discharge nozzle 307; Charging triple valve 1 connects the feed pipe 306 of two filters 3, and discharging triple valve 2 connects the discharge nozzle 307 of two filters 3.
In use, the utility model is installed in the ammoniacal liquor pipeline of equipment, controls one that charging triple valve 1 and discharging triple valve 2 are communicated with in two filters 3, and another is in stand-by state.When obstruction or fault appear in the filter that is in user mode 3; Control charging triple valve 1 and discharging triple valve 2 are communicated with the filter 3 that is in stand-by state; Thereby guaranteed the continuous service of desulphurization denitration equipment, and the filter 3 of obstruction or fault can overhaul or change.
