Abstract
The utility model relates to a centrifugal deduster, which comprises a shell, a centrifugal separation device and a dust collector, wherein the shell is in a cylindrical shape, the top part of the shell is connected with a volute-shaped blower which is connected with a motor through a fixed support, and the lower of the cylindrical shell is sequentially connected a conical barrel body connected with an air inlet pipe, and a material discharge valve and a dust collecting chamber. The utility model has the advantages that the top part of the centrifugal deduster is additionally provided with the volute-shaped blower for exhausting, the lower part thereof is provided with the air inlet pipe, under the condition that an air inlet system has good tightness, a separation pump is in the negative pressure state, the air flow is orderly and stable, the air flow and particles are stabilized and guided, so that the air and solid can be separated, and especially, the air and unltrfine particles can be separated, which are the improvement to the prior art; and the outlet of the blower is provided with an air outlet control valve so as to separate mass with different special gravity and adjust the corresponding air flow speed. The utility model has no high-speed requirement to air flow, has less pressure reduction and less energy consumption, can carry out continuous separation, and has strong separating capability, high dust collecting efficiency, simple structure and convenient separator extraction.
Description
Technical field
The utility model relates to the gas solid separation technical field, and particularly a kind of centrifugal deduster is applied to the collection of the solid particle of the exhaust dedusting of the flue gas ash removal of Industrial Boiler and chemical industry, machine-building and technology.
Background technology
The gas-solid separator that uses has the dust-settling compartment by 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, and the filter bag loss of bag filter is bigger; Cyclone separator is the whizzer of extensive use, all have the complete series product both at home and abroad, gas in the speed of cyclone separator import up to 10～25 meter per seconds, 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, can only select the cyclonic separation group for use, but separative efficiency is low during than monotubular.
The applicant relatively before application revolve the gas deduster, have following weak point:
1, revolve gas deduster separation chamber and work under positive pressure, the pressured air-flow that contracts is sent into indoor, and the air-flow confusion is unfavorable for centrifugation;
2, the gas that rotates at a high speed, its center pressure is little, and nearly housing pressure is big, adopts tangential direction to supply gas, and can be added to the resistance of gas, and supply gas and be the best in the center;
3, horizontally rotate choking coil middle part tight, be unfavorable for the water conservancy diversion of dust.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of centrifugal deduster, have additional the spiral case air blast, at air outlet one leaving air control valve is set, to separate the different specific weight material, regulate corresponding gas speed, the bottom is provided with air inlet pipe, under the good situation of system's air-tightness, the separation chamber is negative pressure, and air-flow is steady in order, and air-flow and particle direction are played stable guide effect, help gas solid separation, especially the separation of ultrafine dust, these are provided with and have improved original weak point, and the particle in the dusty gas is separated fast with gas.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of centrifugal deduster, comprise housing, dust storage chamber, described centrifugal deduster, constitute by housing, centrifugal separating device and dust storage chamber three parts, housing is a cylindrical shape, the top is connected with the scroll casing shape air blast, is connected with motor by fixed mount, and the cylindrical shell below is connected with the divergent-cone wall that is connected with air inlet pipe, blow-off valve and dust storage chamber successively.
The exit of spiral case air blast is provided with a leaving air control valve, is beneficial to the corresponding gas speed of adjusting of different specific weight material.
The cylindrical shell bottom is connected with several feets.
The beneficial effects of the utility model are:
1, sets up the exhaust of spiral case air blast at the top, the bottom is provided with air inlet pipe, under the good situation of air inlet system air-tightness, the separation chamber is negative pressure, air-flow is steady in order, the separation of favourable gas solid separation, especially ultrafine dust, air-flow and particle direction are played stable guide effect, and these are the key improvements to original technology;
2, set out gas control valve at blower export,, regulate corresponding gas speed to separate the different specific weight quality;
3, the 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 big, the dust catching efficiency height, simple in structure, it is convenient to extract separator.
