The utility model relates to a dry type multitubular bag filter and solves the problems that an existing filter is low in dedusting efficiency, poor in safe reliability and short in service cycle. The technical scheme comprises a cylinder body and an inlet end socket and an outlet end socket placed at the two ends of the cylinder body, wherein the upper end of the cylinder body is connected with the inlet end socket through a multitube plate; the lower end of the cylinder body is connected with the outlet end socket through a supporting plate; a plurality of tubular bag type filtering tubes are arranged inside the cylinder body; the upper ends of the tubular bag type filtering tubes are communicated with the inlet end socket; the lower ends of the tubular bag type filtering tubes are sealed. A plurality of air outlets are formed in the supporting plate. The dry type multitubular bag filter is simple in structure, convenient to use, high in dedusting efficiency, long in service cycle and good in safe reliability.

Description

Dry type multi-pipe shape bag filter

Technical field

The utility model relates to a kind of filter, specifically a kind of dry type multi-pipe shape bag filter.

Background technology

At process gas, need in dry desulfurization situation, dry desulfurizing tower (groove) need to be connected on to the gas flow process the inside of process gas compressor.Because desulfurizing agent in use produces powder phenomenon-tion, these solid efflorescence things are brought compressor next stage cylinder into process gas.For reciprocating compressor, solid efflorescence thing can stick on air valve valve seat and valve block, valve disc aperture is reduced, increase resistance, reduce air inflow, solid efflorescence thing is brought cylinder into simultaneously, can make cylinder wall wearing and tearing, increase air leakage, such result has reduced the gas transmission ability of compressor, increases maintenance cost.For centrifugal compressor, solid efflorescence thing can stick to above rotor blade, affects the dynamic balancing of rotor, can cause the increase of unit vibration value, affects the safe operation of unit.

Under above-mentioned operating mode, in order to remove solid efflorescence thing, conventionally adopt filler filtration method, filler has glass fibre, Raschig ring, porcelain ball etc.These method dust removal by filtration efficiency are low, can not protect long period, safety, the stable operation of compressor.

Summary of the invention

The purpose of this utility model is in order to solve the problems of the technologies described above, and provides a kind of simple in structure, easy to use, the dry type multi-pipe shape bag filter that efficiency of dust collection is high, life cycle is long, security reliability is good.

Technical scheme comprises cylindrical shell and is positioned at the air inlet end socket at cylindrical shell two ends and the end socket of giving vent to anger, the upper end of described cylindrical shell is connected with air inlet end socket through multitube plate, lower end is connected with the end socket of giving vent to anger through gripper shoe, in described cylindrical shell, be provided with many tubular bag type filtering pipes, the upper end of described tubular bag type filtering pipe is communicated with air inlet end socket, lower end end part seal, has a plurality of ventholes in described gripper shoe.

The upper end of described tubular bag type filtering pipe is fixed on upper perforated plate and with air inlet end socket and is communicated with, lower end end part seal and pegging graft with gripper shoe.

Described tubular bag type filtering pipe comprises body and is sleeved on the filter bag in body, and described body surface has a plurality of passages, and described filter bag and body are the tubular structure of upper end open, lower end closure.

Process gas can enter in tubular bag type filtering pipe by upper cover, utilize tubular bag type filtering pipe to filter the dust in process gas, process gas after filtration enters in the cylindrical shell outside tubular bag type filtering pipe, finally through the venthole in gripper shoe, by low head, is discharged.In the utility model, described tubular bag type filtering pipe adopts the form of pipe box bag, at body inner sleeve filter bag, body plays the effect of support, filter bag can filter process gas, the solid efflorescence thing leaching is attached in filter bag, after deposition, form filter cake, along with thickening of filter cake, weight increases, under the effect of gravity, filter cake can peel off the bottom of calling in filter bag automatically, by regularly, to the cleaning of filter bag or replacing, can guarantee the efficient stable operation of filter, the passage of the process gas after filtration on body enters in cylindrical shell.The utility model good filtration effect, efficiency of dust collection high (dust removal efficiency can reach more than 99%), it is convenient that filter bag is used, changes, and easy access can guarantee the long-term stability operation of system.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further explained to explanation:

With reference to Fig. 1-Fig. 3, the upper end of cylindrical shell 1 is connected with air inlet end socket 2 through multitube plate 4, lower end is connected with the end socket 3 of giving vent to anger through gripper shoe 7, described air inlet end socket 2 is provided with gas feed 8 and manhole 10, the end socket 3 of giving vent to anger is provided with gas vent 9, in described cylindrical shell 1, be provided with many tubular belt screen pipes 6, the upper end of described tubular bag filter 6 is fixed on multitube plate 4 and with air inlet end socket 2 in the mode of welding that to be communicated with (be that gas can be by gas feed 8, the upper end of tubular belt screen pipe 6 enters in pipe), the lower end of described tubular bag filter 6 and gripper shoe 5 are pegged graft, tubular like this bag type filtering pipe 6 is suspension status in cylindrical shell, like this, when tubular belt screen pipe 6 overhauls and changes, only need root out the pad of tubular bag filter 6 upper ends.Described tubular bag filter 6 comprises that body 61(is steel pipe) and be sleeved on the filter bag 62 in body 61, described filter bag 62 materials can be nylon cloth, glass cloth, flat, suede cotton crash woolen material etc., it makes the internal diameter that size external diameter is slightly less than body 61, filter bag 62 upper end open can hang over the opening part of body 61 upper ends, and lower end sews up to be closed.Preferred filter bag 62 length equal body 61 length and separately add 100 ~ 200mm.Described body 61 is also upper end open, the tubular structure of lower end involution.On the pipe face of body 61, have a plurality of passages 63, the quantity of described passage 63, aperture and effective area should be according to throughput appropriate design, and the diameter in optimizing breathing hole 63 is 6 ~ 30mm.In described gripper shoe 5, also have a plurality of ventholes 7 for the gas in cylindrical shell 1 is drawn to cylindrical shell 1, and finally by gas vent 9, discharged.

Operation principle:

The process gas of dust-laden is entered again in the upper end of tubular bag filter 6 enters the filter bag 62 in pipe by gas feed 8, after the filtration of filter bag 62, by the passage 63 on body 61, entered in cylindrical shell 1, finally by the venthole 7 in gripper shoe 5, discharge cylindrical shell, through gas vent 9 discharge filters, the solid efflorescence thing filtering down is attached in filter bag 62, by the mode of regularly knowing filter bag or changing filter bag, guarantees that the long-term stability of filter moves.
