Description
Technical field
The utility model relates to a kind of industrial sack cleaner bypath system, belongs to the power plant equipment technical field.
Background technology
At present, the built-in bypath system of known sack cleaner is on air inlet flue and the dividing plate between the flue of giving vent to anger one group of bypass valve to be set, Fig. 1 is the built-in bypath system structural representation of existing sack cleaner, after bypass valve is opened, flue gas directly enters the flue of giving vent to anger from the air inlet flue by bypass valve, and without the cloth bag filtration; After bypass valve cuts out, flue gas will be divided to each bag chamber, enter the flue of giving vent to anger behind the cloth bag filtration again.But; often make the sealing effectiveness variation after the long-term use of bypass valve because of reasons such as wearing out of sealing gasket; when deduster is in the filtration state; make the part ash-laden gas directly bypass without the cloth bag filtration; cause efficiency of dust collection to descend; simultaneously, the replacing of bypass valve sealing gasket need be shut down processing, has influenced normal production.
The utility model content
Technical problem to be solved in the utility model is the shortcoming that overcomes existing sack cleaner bypath system sealing effectiveness difference, and a kind of long-term efficient sealed sack cleaner bypath system that can realize bypass valve easily is provided.
For solving the problems of the technologies described above, the utility model provides a kind of sack cleaner built-in bypath system, comprise the air inlet flue, give vent to anger flue and be arranged at the air inlet flue and the dividing plate between the flue of giving vent to anger, it is characterized in that: the front end at the flue of giving vent to anger is provided with a casing, described casing and flue wallboard are affixed, the lower wall panels of described casing is connected with described dividing plate, lower wall panels is divided into lower wall panels air inlet side and the lower wall panels side of giving vent to anger, in the lower wall panels air inlet side of casing and the lower wall panels side of giving vent to anger one group of bypass valve is set respectively, two tracheaes are set on the top of casing, one termination of first tracheae is gone in the casing, the other end is connected to the outlet of boiler induced-draft fan or directly places atmosphere, one termination of second tracheae is gone in the casing, and the other end is connected to the flue of giving vent to anger.
First tracheae and second tracheae are provided with valve and Pressure gauge.
Described bypass valve is a flap valve, has the valve opening of circular hole as bypass valve on the lower wall panels of casing.
The built-in bypath system operation principle of sack cleaner of the present utility model is: insert two tracheaes in casing, the other end of a tracheae is connected to the outlet of boiler induced-draft fan, import clean flue gas in this casing, between bypass valve valve opening and valve plate, form hermetic seal, also can directly this root air inlet pipe be positioned in the atmosphere, rely on the negative pressure suction air in the deduster in casing, to form hermetic seal; The other end of another root tracheae is connected to the flue of giving vent to anger, and the gas in the casing can be discharged by this root tracheae; Valve and Pressure gauge are housed, by the pressure in the keying adjustable case body of valve on the tracheae.When deduster was in bypass condition, two groups of bypass valves were all opened, and flue gas detours through two groups of bypass valves from the air inlet flue and enters the flue of giving vent to anger; When deduster was in the filtration state, two groups of bypass valves all cut out, and seal bypass valve by the gas in the casing.
The beneficial effect that the utility model reached: the built-in bypath system of sack cleaner of the present utility model, the setting by casing and two tracheaes makes the bypass valve good sealing effect; do not have and leak, efficiency of dust collection improves, simultaneously; this bypath system is long service time, need not shut down maintenance.
