Abstract
This utility model provides a kind of boiler blast cap, including: column body segment, for hollow circular tube structure, wherein the diameter of one end is more than the diameter of the other end, and excessive for taper between two ends；Stigma section, closes the drum-shaped structure of other end opening, is evenly distributed with air vent in circumference side for one end, and it is fixed by one end that opening is big with described column body segment diameter and is connected；Abrasionproof section, is arranged on described column body segment and the junction of described stigma section, and its surrounding radially protruding is in described column body segment and the external peripheral surface of described stigma section.Blast cap material of the present utility model uses two-way integrally casting without nickel steel, and when boiler works, wind is entered by column body segment, the air vent of stigma section uniformly deliver to be sent into burner hearth by wind, and in ventilation process, dust is blocked by abrasionproof section, thus avoids stigma section and be worn.This product structure is simple, easy for installation, solves tradition blast cap easy to wear, and the problems such as deslagging is low, the safety and economic operation for boiler provides guarantee.
Description
Technical field
This utility model relates to field of boilers, particularly relates to a kind of wind being applied on boiler recirculating fluidized bed
Cap.
Background technology
Blast cap is the important accessory of boiler recirculating fluidized bed and combustor, and blast cap is arranged on air distribution plate, it
Main Function is that the wind of fluidized bed combustion is sent into burner hearth uniformly.The abrasion of blast cap and damage can directly affect pot
Stove cloth wind is uneven, thus the operation of boiler and the furnace wall etc. of boiler thereof are caused and had a strong impact on.Boiler at present
Blast cap mainly has three types, the most T-shaped blast cap, bell-type windshield, placed arrow type blast cap.T-shaped blast cap
Deslagging performance is strong, but the abrasion between blast cap is more serious.Fluidized state near its blast cap of bell-type windshield is poor,
Its deslagging performance is the most poor.And placed arrow type blast cap equally exists serious wear, the situation of the easy accumulated slag of air compartment.
Utility model content
The purpose of this utility model is to provide for one and is applied on boiler recirculating fluidized bed to reduce abrasion journey
The blast cap of degree.
Especially, this utility model provides a kind of boiler blast cap, including:
Column body segment, for hollow circular tube structure, wherein the diameter of one end is more than the diameter of the other end, and two ends
Between for taper excessive；
Stigma section, closes the drum-shaped structure of other end opening, is evenly distributed with logical in circumference side for one end
Air holes, it is fixed by one end that opening is big with described column body segment diameter and is connected；
Abrasionproof section, is arranged on described column body segment and the junction of described stigma section, and its surrounding radially protruding is in institute
State column body segment and the external peripheral surface of described stigma section.
Further, described abrasionproof section be shaped as rectangle.
Further, the thickness of described anti-frosted section is 1 with the length ratio of described stigma section and described column body segment:
3:10.
Further, the blind end of described stigma section is outwardly circular arc.
Blast cap material of the present utility model uses two-way integrally casting without nickel steel, and when boiler works, wind is by post
Body section enters, the air vent of stigma section uniformly deliver to be sent into burner hearth by wind, and in ventilation process, dust is prevented
Mill section is blocked, thus avoids stigma section and be worn.This product structure is simple, easy for installation, solves biography
System blast cap is easy to wear, and the problems such as deslagging is low, the safety and economic operation for boiler provides guarantee.
Accompanying drawing explanation
Fig. 1 is the boiler cap structure schematic diagram according to one embodiment of this utility model.
Detailed description of the invention
As it is shown in figure 1, the boiler blast cap of one embodiment of this utility model includes integrally casting in general manner
Column body segment 10 and stigma section 20, and abrasionproof section 30 between.
This column body segment 10 is hollow circular tube structure, and wherein the diameter of one end is more than the diameter of the other end, and
It is that taper is excessive between two ends.
This stigma section 20 closes the drum-shaped structure of other end opening for one end, is uniformly distributed in circumference side
Having air vent 21, it is fixed by one end that opening is big with column body segment 10 diameter and is connected.
This abrasionproof section 30 is arranged on column body segment 10 and the junction of stigma section 20, its surrounding radially protruding in
Column body segment 10 and the external peripheral surface of stigma section 20.
The blast cap material of the present embodiment uses two-way integrally casting without nickel steel, and when boiler works, wind is by cylinder
Section 10 is internal to be entered, the air vent 21 of stigma section 20 uniformly deliver to be sent into burner hearth, ventilation process by wind
In, dust is blocked by abrasionproof section 30, thus avoids stigma section 20 and be worn.This product structure is simple,
Easy for installation, solve tradition blast cap easy to wear, the problems such as deslagging is low, for the safety and economic operation of boiler
Provide guarantee.
Further, for convenience of installing, the shape of this abrasionproof section 30 can be rectangle.Enforcement at other
In example, it is also possible to according to mounting structure, this abrasionproof section 30 is shaped to circle.For reducing resistance,
The blind end of this stigma section 20 can be outwardly circular arc.
For preferably reaching abrasionproof purpose, the thickness of this anti-frosted section 30 and stigma section 20 and column body segment 10
Length ratio can be 1:3:10.
So far, although those skilled in the art will appreciate that the most detailed to illustrate and describe this practicality new
Multiple exemplary embodiments of type, but, in the case of without departing from this utility model spirit and scope, still
Can directly determine according to this utility model disclosure or derive the many meeting this utility model principle
Other variations or modifications.Therefore, scope of the present utility model is it is understood that and regard as covering all these
Other variations or modifications.
