Technical Field

The utility model relates to a double-walled pipe extruder unit tail gas clean-up system.

Background

PE plastics are melted and extruded into a forming machine from an extruder to prepare a PE double-wall corrugated pipe, harmful tail gas is generated in the melting process, the tail gas drifts into the air of a workshop to bring adverse effects on the body health of workers in the workshop, and meanwhile, in the process of closing a door of the workshop, the tail gas drifts out of the workshop to pollute the air around a factory.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an extruder unit tail gas clean system, can purify the back to the harmful tail gas that the extruder produced and discharge, prevent tail gas pollution mill's air, avoid the tail gas harm workman healthy.

In order to solve the above problem, the to-be-solved technical scheme of the utility model is:

double-walled pipe extruder unit tail gas clean-up system, including the house steward that bleeds, the house steward that bleeds is through many spinal branchs pipe and the gas collecting channel switch-on of setting in each extruder top, blind flange seals is passed through to house steward one end that bleeds, one end in addition in proper order with the draught fan, spray the jar, ion wind purifier and photocatalytic cleaner intercommunication, be equipped with the defogging board in spray the jar, shower and filler support, the shower passes through inlet tube and spray tank bottoms portion intercommunication, install the water pump on the inlet tube, it packs to be equipped with the fretwork ball on filler support.

The straight tube is including fixed pipe and bent pipe, fixed pipe one end and exhaust manifold intercommunication, and fixed pipe other one end and exhaust chamber intercommunication, exhaust chamber one side intercommunication have the central siphon, and bent pipe one end is rotated and is connected in the central siphon, and the other one end of bent pipe communicates with the gas collecting channel, is equipped with the hoist engine on branch pipe top factory building stand, and hoist engine wire rope and the clamp connection of fixed connection on the bent pipe.

Each branch pipe is provided with an electromagnetic valve.

The utility model has the advantages that:

1. the tail gas that the extruder group produced is pumped by the draught fan and is sent to spraying the jar and receive the water film purification, gets rid of dust and harmful particulate matter in the tail gas, then discharges after abundant oxidation in ion wind clarifier and the photocatalytic cleaner, eliminates the irritability peculiar smell in the tail gas, thoroughly clears away the harmful substance in the tail gas, makes the extruder group production process more green.

2. When some extruders need to be overhauled, the branch pipes can be lifted in a rotating mode, and operation of workers is facilitated.

Drawings

The invention will be further explained with reference to the drawings:

figure 1 is a schematic structural diagram of the present invention,

FIG. 2 is a schematic side view of the present invention,

fig. 3 is a schematic diagram of the local enlarged structure of the present invention.

In the figure: the device comprises an extruder 1, a gas collecting hood 2, a bent pipe 3, an air exhaust box 4, a fixed pipe 5, an electromagnetic valve 6, a winch 7, an air exhaust main pipe 8, a draught fan 9, a spray tank 10, an ion air purifier 11, a photocatalytic purifier 12, a demisting plate 13, a spray pipe 14, a hollow ball filler 15, a filler support 16, a water pump 17 and a shaft pipe 18.

Detailed Description

As shown in fig. 1 to 3, double-walled pipe extruder group tail gas clean-up system, including air exhaust manifold 8, air exhaust manifold 8 is through many spinal branchs pipe and the switch-on of gas collecting channel 2 who sets up in each extruder 1 top, air exhaust manifold 8 one end is sealed through blind flange, one end in addition in proper order with draught fan 9, spray tank 10, ion wind clarifier 11 and photocatalysis purifier 12 intercommunication, be equipped with defogging board 13 in spray tank 10, shower 14 and filler support 16, shower 14 is through inlet tube and spray tank 10 bottom intercommunication, install water pump 17 on the inlet tube, be equipped with PP fretwork ball filler 15 on filler support 16. The ion wind purifier 11 and the photo-catalytic purifier 12 may be selected from DLZ type plasma wind purifier 11 and GY type photo-oxygen catalytic purifier manufactured by "cangzhou science and trust environment protection machinery limited".

The utility model discloses during the use, the main 1 discharge gate position of extruder of concentrating on of the smell that extruder 1 wafts, consequently, can place gas collecting channel 2 in 1 discharge gate top of extruder, after draught fan 9 starts, draught fan 9 extracts the tail gas that extruder 1 effluvium and enters into behind branch pipe and house steward in the spray tank 10, spray tank 10 in spray tank 14 spray water smoke process PP fretwork ball formation water film, make tail gas can be sufficient and the water contact, eliminate behind the particulate matter in the tail gas and discharge through ion wind clarifier 11 and photocatalysis clarifier 12 in proper order, eliminate the irritability peculiar smell in the tail gas, thoroughly clear away the harmful substance in the tail gas, make 1 group production process of extruder more green.

The straight tube includes fixed pipe 5 and bent pipe 3, and 5 one end of fixed pipe and 8 intercommunications of exhaust manifold, fixed pipe 5 other one end and exhaust chamber 4 intercommunication, and 4 one side intercommunications of exhaust chamber have central siphon 18, and 3 one ends of bent pipe are rotated and are connected in central siphon 18, and 3 other one ends of bent pipe and gas collecting channel 2 intercommunications are equipped with hoist engine 7 on the factory building stand of branch pipe top, and 7 wire rope of hoist engine are connected with the clamp of fixed connection on bent pipe 3. When the extruder 1 needs to be overhauled, the gas collecting hood 2 and the curved pipe 3 can be pulled up through the winch 7, and the extruder 1 is convenient for workers to overhaul.

Each branch pipe is provided with an electromagnetic valve 6. The motor that draught fan 9 used can be inverter motor, when partial extruder 1 shut down, then can close solenoid valve 6 on the branch pipe above the extruder of shutting down 1, and then inverter motor deceleration reduces inverter motor power, reduces power consumption, can guarantee the extraction of other work extruder 1 tail gases simultaneously and purify.
