Abstract
The utility model relates to a device for recovering coarse particle materials of exhaust gas in a coal drying system, in particular to a cyclone separator, which comprises an inlet volute and a cone, wherein the cone consists of two parts, namely a middle cone and a lower cone which are connected with each other through a flange; the lower part of the middle cone is provided with an observation door; the bottom of the lower cone is provided with a surge hopper; and fireproof and abrasion-resistant coatings are laid on inner walls of the middle cone and the lower cone. Compared with the prior art, the cyclone separator has the advantages that the cone takes the structure of two sections which are connected with each other through the flange, and the length of the lower cone is approximately between 800 and 500 millimeters, so that the cone is convenient to replace once worn; the lower part of the middle cone is provided with the observation door, so that the condition of the inner wall of the separator can be observed once the door is opened under the condition of overhaul of the device and the service failure of the separator can be avoided; the bottom of the separator is provided with the surge hopper which can realize fluidity sealing of underflow of the separator, so that the separation efficiency is improved; and the fireproof and abrasion-resistant coatings are laid on the whole inner wall of the separator, so that the heat-insulating effect and the abrasion-resistant performance of the separator are improved.
Description
Technical field:
The utility model relates to the reclaimer of the coarse granule material of waste gas in the coal drying system, especially a kind of cyclone separator.
Background technology:
In the coal drying system cyclone separator commonly used as waste gas in the reclaimer of coarse granule material, cyclone separator generally is made of inlet volute, lower cone two large divisions, lower cone bottom in the use is because the dust wearing and tearing are easy to damage, cause the cyclone separator lower cone all to be changed, because of lower cone long (about 3400mm), very inconvenience of on-the-spot replacing; In addition, because of separator is totally-enclosed design, and the waste gas in the coal drying system has uniform temperature, in case the waste gas dewfall, coal dust easily is stained with on the inwall that is bonded at separator and is difficult for being found, and causes accident.
Summary of the invention:
The technical problems to be solved in the utility model is to improve above-mentioned defective, and a kind of easy to maintenance, cyclone separator that damageable zone is easy to change, have the underflow self-sealing function is provided.
The technical scheme that addresses the above problem employing is: a kind of cyclone separator, comprise inlet volute, cone, described cone is made up of middle cone and lower cone two parts, flange connects between the two, middle cone bottom is provided with observes door, surge hopper is equipped with in the lower cone bottom, and middle cone and lower cone inwall are equipped with the fire prevention wear-resistant coating.
Compared with prior art, the novel beneficial effect of this use is:
1. cone is the two-part structure that flange connects, and lower cone length is about between 800～500mm, in case wearing and tearing, it is very convenient to change.
2. the bottom of middle cone is provided with and observes door, opens this door during overhaul of the equipments, can be observed the situation of separator inwall, in time avoids the separator operational failure.
3. surge hopper has been set up in the separator bottom, and this surge hopper can be realized the flowability sealing of separator underflow, improves separative efficiency.
4. the separator inwall is all laid the fire prevention wear-resistant coating, has improved the heat insulation effect and the abrasion resistance of separator.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: inlet volute 1, middle cone 2, lower cone 3, surge hopper 4, flange 5 is observed door 6, fire prevention wear-resistant coating 7.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of cyclone separator that present embodiment provides as shown in the figure, the inlet volute 1 of its log spiral is in separator cone top, described cone is made of middle cone 2 and lower cone 3 two parts, connect by flange 5 between the two, when lower cone 3 serious wear need be changed, unclamping flange 5 was detachable lower cone 3; Middle cone 2 bottoms are provided with observes door 6, in case work condition abnormality appears in separator, can open observation door 6 easily and check; Surge hopper 4 is installed by flange in lower cone 3 bottoms, and when meeting large granular materials, material is piled up in earlier in the surge hopper 4, with the accumulation gradually of material, under the gravity effect, is discharged by surge hopper 4 again, realizes the mobile sealing of separator underflow with this; For improving the heat insulation effect and the abrasion resistance of separator, at least at middle cone 2 and lower cone 3 inwalls or whole shell separator inwall laying fire prevention wear-resistant coating 7.
