Abstract

The utility model discloses a constant temperature cyclone dust collector, belonging to the dust remover, which is characterized in that a heating layer is positioned respectively outside an inlet pipe section, a sedimentation section, an aggregate ash hopper section of the housing of the cyclone dust collector; an insulation layer is positioned on the periphery of the heating layer; a temperature resistance and wearproof lining plate is positioned correspondingly on the inner walls of inner pipe section, sedimentation section and the aggregate ash hopper section of the housing; the heating layer is an annular gas chamber or a spiral pipeline surrounding the housing; the high temperature steam is introduced continuously through the inlet of the annular gas chamber or the spiral pipeline so that the gas in the intracavity of the dust collector can be heated evenly; as a result, the gas in the intracavity of the dust collector of the dust collector can be kept in constant temperature or warmed up; therefore, the temperature of the gas containing the dust can not be reduced in the process of dedusting and the condensate water can not occur in the cyclone dust collector; the ash in the dust hopper can not bond together, which is easy to discharge and can meet the needs of special occasions.

Description

The constant temperature cyclone dust collectors

Technical field

The utility model belongs to dust arrester, especially relates to a kind of cyclone dust collectors.

Background technology

In the dust-laden exhaust gas processing procedure of large-sized industrial kiln, commonly used to cyclone dust collectors, this deduster presses the eddy flow dusty gas to enter in the inner chamber based on air inlet with band, in the housing of cyclone dust collectors, tangentially enter by housing, advance along the helicoid rotation, make dust-contained airflow do the tilting screw motion downwards, assembled along sliding under the inner walls in the ash bucket cone of bottom by the dirt powder in the centrifugal action gas, again discharging regularly, clean gas reaches emission request, existing common cyclone dust collectors, the dusty gas of source of the gas are after dedusting, and temperature reduces, condensed water can appear in the deduster, cause dust bonding in the ash bucket, unload the ash difficulty, need set up rapping machinery separately, to some occasion that requires the temperature of dusty gas to keep constant temperature or increase to a certain temperature, existing cyclone dust collectors can't address that need.

Summary of the invention

The purpose of this utility model is to propose a kind of constant temperature cyclone dust collectors, make dusty gas cooling in dedusting, not occur, condensed water does not appear in the cyclone dust collectors, dust is non-caked in the ash bucket, very easily unload ash, need not increase rapping equipment separately, and dusty gas constant temperature that can be in specific occasions keeps deduster or be increased to a certain temperature, satisfy specific needs.

The purpose of this utility model is achieved like this: a kind of constant temperature cyclone dust collectors, its housing is from top to bottom by the pipeline section of giving vent to anger, the air inlet pipeline section, settling section, heavy flue-dust retainer section, support is formed, the escape pipe section is positioned at the top of deduster, from then on clean gas after dedusting discharges, the dusty gas of wait dedusting is introduced in the deduster inner chamber from the air inlet pipeline section, dusty gas is done oblique screw at settling section, assembled along sliding in the ash bucket under the inner walls by the centrifugal action dust, discharging regularly again, it is characterized in that air inlet pipeline section at the housing of cyclone dust collectors, settling section, the outside of heavy flue-dust retainer section, the layer of heating all is set, periphery at the layer of heating is provided with heat-insulation layer, and at the air inlet pipeline section of housing, settling section, equal correspondence is provided with the heat-resistant, wear-resistant liner plate on the inwall of heavy flue-dust retainer section, this layer of heating is ring-shaped air chamber or helical pipe around housing, import high-temperature steam continuously from the inlet of ring-shaped air chamber or helical pipe, gas in the balanced heating deduster inner chamber, regulate the quantity of steam that enters as required, the constant temperature or the intensification that keep the gas in the deduster inner chamber, the steam that has vapored away heat enters the atmosphere or in the jet chimney from the outlet of ring-shaped air chamber or helical pipe.

The constant temperature cyclone duster structure that the utility model proposes is simple, safe and reliable, both can make dusty gas cooling in dedusting, not occur, condensed water does not appear in the cyclone dust collectors, dust is non-caked in the ash bucket, very easily unload ash, need not increase rapping equipment separately, and dusty gas constant temperature that can be in specific occasions keeps deduster or increase temperature, satisfy specific needs.

Now the constant temperature cyclone dust collectors of in conjunction with the accompanying drawings and embodiments the utility model being carried are further described.

Description of drawings

Fig. 1 is that the master of the constant temperature cyclone dust collectors that propose of the utility model looks schematic diagram.

Among Fig. 1: 1, give vent to anger pipeline section 2, air inlet pipeline section 3, settling section 4, heavy flue-dust retainer section 5, heat layer 6, heat-insulation layer

The specific embodiment

As can be seen from Figure 1: a kind of constant temperature cyclone dust collectors, its housing is from top to bottom by the pipeline section 1 of giving vent to anger, air inlet pipeline section 2, settling section 3, heavy flue-dust retainer section 4, support is formed, the pipeline section 1 of giving vent to anger is positioned at the top of deduster, from then on clean gas after dedusting discharges, the dusty gas of wait dedusting is introduced in the deduster inner chamber from air inlet pipeline section 2, dusty gas is done oblique screw at settling section 3, assembled along sliding in the ash bucket under the inner walls by the centrifugal action dust, discharging regularly again, it is characterized in that air inlet pipeline section 2 at the housing of cyclone dust collectors, settling section 3, the outside of heavy flue-dust retainer section 4, the layer 5 of heating all is set, periphery at the layer 5 of heating is provided with heat-insulation layer 6, and at the air inlet pipeline section 2 of housing, settling section 3, equal correspondence is provided with the heat-resistant, wear-resistant liner plate on the inwall of heavy flue-dust retainer section 4, this layer 5 of heating is ring-shaped air chamber or helical pipe around housing, import high-temperature steam continuously from the inlet of ring-shaped air chamber or helical pipe, gas in the balanced heating deduster inner chamber, regulate the quantity of steam that enters as required, the constant temperature or the intensification that keep gas in the deduster inner chamber, the steam that has vapored away heat enters the atmosphere or in the jet chimney from the outlet of ring-shaped air chamber or helical pipe.
