Description

Revolve the gas deduster

The utility model relates to the gas solid separation technical field, and the flue gas ash removal and chemical industry, the exhaust dedusting of machine-building and the solid material of technology that are applied to Industrial Boiler separate.

In order to control atmosphere pollution, Industrial Boiler all need be provided with deduster, and the separator that uses has the dust-settling compartment with gravitational settling, the filtration dust catcher of filter course, the cyclone separator of centrifugal sedimentation etc. at present.Because the sinking speed of particle is little,, and only be suitable for crude separation so dust-settling compartment is bulky; Filtration dust catcher commonly used has the laminar deduster of filling and bag filter, when air communication is crossed filter course pressure drop big, power consumption is also big, uses the filled type deduster, must often change or cleans packed layer, the filter bag loss of bag filter is bigger; Cyclone separator is the centrifugal settler of extensive use, all has the complete series product both at home and abroad.Gas in the speed of cyclone separator import up to the 10-25 meter per second, in theory, just can improve separating power as long as increase gas speed, but in fact when increasing gas speed, pressure drop and power consumption also sharply increase, so, the size of gas speed is subjected to the restriction of allowable pressure drop, when handling tolerance when big, have to select for use the cyclonic separation group, but separative efficiency is low during than monotubular.

The purpose of this utility model is to provide that a kind of new continuous separates dedusting method revolves the gas deduster, makes the particle in the dusty gas can be separated from the gas fast.

Design of the present utility model is:

Partly form by housing, centrifugal separating device, dust storage chamber three; It is characterized in that:

Housing is a divergent-cone wall, and the below is provided with air inlet pipe and air inlet, and the top is provided with several gas outlets, and the top is a protective cover, and the cylindrical shell internal upper part has a upper cover plate, and housing bottom also can be provided with several feets;

Centrifugal separating device, constitute by motor, hollow rotating shaft, axial baffle, annular centrifugal film, fan blade and electric machine support, motor is packed on the fixed head with electric machine support, bearing, fixed head and upper cover plate welding are fixing, the hollow rotating shaft top is connected with motor, the lower end is connected with fan blade, and the hollow rotating shaft periphery is provided with several axial baffles, and axial baffle is arranged with several pieces annular centrifugal films;

Dust storage chamber is the dust storage chamber that has switch.

The utility model has the advantages that:

Air-flow to import does not have the high speed requirement, and pressure drop is little, and energy consumption is little, can separate continuously, and separating power is big, and the dust catching efficiency height, it is convenient to extract separator, and simple in structure, volume is little, and the scope of application is wide.

Below in conjunction with accompanying drawing structure technology feature of the present utility model is described further.

The 4-feet.

Embodiment one:

Fig. 1 revolves gas deduster structural representation for suction-type of the present utility model, partly is made up of housing 1, centrifugal separating device 2, dust storage chamber 3 three;

Housing 1 is a divergent-cone wall, and the below is provided with air inlet pipe 14 and air inlet 15, and there are several gas outlets 11 upper end, and the top is a protective cover 12, and the cylindrical shell internal upper part has a upper cover plate 13, and housing 1 bottom also can be provided with several feets 4;

Centrifugal separating device 2, constitute by motor 22, hollow rotating shaft 25, axial baffle 26, annular centrifugal film 27, fan blade 28, electric machine support 21, motor 22 usefulness electric machine supports 21, bearing 23 are packed on the fixed head 24, fixed head 24 is fixing with upper cover plate 13 welding, hollow rotating shaft 25 tops are connected with motor 22, the lower end is connected with fan blade 28, and hollow rotating shaft 25 peripheries are provided with 3-4 axial baffle 26, and axial baffle 26 is arranged with several pieces annular centrifugal films 27 (the sheet number is decided on the deduster height);

Dust storage chamber 3 is for having the dust storage chamber of switch, is used to collect the fixedly grit after the separation.

During work, open motor 22 earlier, make and revolve gas deduster casing and be in the exhausting duty, dust-contained airflow sucks air inlet pipe 14 from air inlet 15, dust-contained airflow upwards rotates in the shape of a spiral, and air-flow is drained from the exit, top through the clean gas after separating, and grit is getting rid of under action of centrifugal force to the cylindrical shell perisporium in the rotation at a high speed, under the double action of gravity and cone-shaped perisporium, drop to dust storage chamber 3.When dust discharge, the switch of switch Ji Ji chamber 3 must be in closed condition, to guarantee the stability and the continuity of separation process.
