1.Some technological innovations of cleaning system of exhaust gas.
Our company according to for many years for the whole country every large exhaust gas purification practical experience of system equipment that aluminum smelter manufacture, The actual operation of the system equipment result, improve and perfect as follows.

1) Should increase the fresh aluminum automatic distributor in the cleaning system of exhaust gas , its merit is: Very automatic to assign fresh aluminum to every amount of material given of dust remover while being even, Make every dust remover able to work under the best state, thus reduced the emission of the fluoride greatly, Service life lengthenning the cloth of straining.

2) Should increase exhaust gas assign device, to enter exhaust gas of dust remover want and adopt automatic to assign while being even, Make each dust remover enter exhaust gas volumn equally, can improve and get rid of Fluorine efficiency greatly in this way, Each dust remover temperature equal, imports and exports equal to pigeonhole difference, improve the working efficiency of the dust remover.

3) The axle bush temperature that mainly arranges the air blower of cigarette should be able to show in the display screen of the computer, Temperature can exceed standard autoalarm, in this way can protect and arrange air blower of cigarette damage mainly.

4) Arrange air blower circulating water normal cigarette mainly ,it should show in the display screen of the computer, The circulating water is abnormal but autoalarm.

5) Flow state spend Luo thatch air blower and that lifting machine spend Luo thatch wind engine( electromechanics) shed size strength. Axle bush temperature high mental deficiency shows out in the display screen of the computer, the trouble can report to the police.

6) All air cylinders installed on the dust remover . Electromagnetic valve. Which movement. Every one does not act . Every out of order to should show out on the display screen, the trouble can report to the police.

7) Exit install dust detector in dust remover, can measure how many filter bag broken to leak dust removers does it publish, In order to repair, reduce losses of the alumina powder.

8） Fresh alumina conveyer system install additional and get rid of the sand device, guarantee that the alumina stops up the material.

2.Several points of the ultra dense looks conveyer system improve and technological innovation.
Our company, according to producing experience, the real operation conditions of conveyer system of ultra dense looks of alumina of every large aluminum smelter of the whole country for many years, Combine foreign advanced technology, make the following improving and technological innovation to the ultra dense.

1) Wind -supply system high pressure centrifugal air blower enter draught install have wind pressure, wind amount mediate the device automatically. The constantly changeable wind pressure but according to the system. Wind amount, mediate the switch of entering the draught place, basic invariable system pressure automatically, Can show the wind pressure of every position in the course of sending.

2) In the conveyer system, get up from end to end and is equipped with the two-way regulating valve, control each section of ventilation, Adjust into the pressure gradient.

3) Send and slip away trough wall scribble and have wear-resisting to decrease the coating, lengthen service life.

4) For reduce obstruction of sending, system reduce and slip away trough connect, each slip away trough make and slip away the trough size according to two electrolytic trough interval. Slip away in the wind room of the trough. Material room divide into two part, prevent wind room from enter alumina possibility of powder.

5) In order to perfect the ultra dense further, our company has allocated the advanced computer control system.

6) The automatic system adopts the control Company that PLC processed the accusing of machine, the next machine adopts S7 series of SIEMNS; The location machine has function of touch-sensitive screens, PIII850 worker's accusing of machine to adopt LCD display screen on PLC. Grasp the wind pressure controlled. Flow. Reinforced devices and air blowers of the electrolytic trough material. Wind pressure.wind amount. Electric current. prepare burden it measure systematically.

7) If users need, can adopt the multimedia to show, adopt LCD touch-sensitive screen and advanced accusing of machine of worker in the system, Can observe, send all course, operate on canning realize and reject in control room. The air blower is opened and stops. Regulate manually. Such functions as the accident reports to the police.

3.Characteristic and application of the sack cleaner of slight shock that MW type pulses.
Model MW dust remover in accumulate for many years making and draw of various fields specialty one performance fine high-efficient sack cleaner of design and manufacture our company with use experience foundation.

1）Having whirlwind and function of filtering second dust removal, dust removal efficiency can be up to more than 99.5%, Entry dust density than similar bags of dust remover high more than first time of straining etc., reach as high as 120 g/m²s. Because already the whirlwind has been separated in thick particle and dust, have reduced the impact of the filter bag and grit, Therefore the life- span of the filter bag is than generally is long.

2）Blowback clear dust adopt pulse clear gray organization , make filter bag shake and shake and fall and enclose dust on the sack, Clear gray ability is generally higher than one bag of straining type dust remover s, it is good to resume filtering performance.
3）Take fine sealed measure, leak out rate in 5% under.
This dust remover is divided into a room, a three kinds of patterns in the room, storehouse. Room appearance MW have 4 series 17 specification , filter area 50 mm² since to 1000 mm²; Room interior MW one N have 4 series 12 specification, filter area 40 mm² to 450 mm², its structure is essentially identical with appearance of the room since, Change into hod flat to unload gray pattern only, have and enter wind switch over to the enterprising wind, highly reduce, Suitable for installing in the room; Storehouse carry type MW-C have 1 series 7 specification, filter area 20 mm² to 110 mm², structure its cancel hod and enter draught since, Benefit the installation on storehouse carrying and general craft hopper.

This dust remover is suitable for purification of different dust of the trade, such as metallurgical material, refractory material, chemical industry, machinery, light industry, grain processing, medicine,etc. and retrieves.
