Abstract
The utility model discloses a concentrated phase bilge pump fluidization nozzle, which comprises a bilge pump (transmitter), and a fluidization air pipeline, and is characterized in that the end of the fluidization air pipeline inside the bilge pump is connected with the fluidization nozzle; the fluidization nozzle structure is provided with a large adaption pipe and a small adaption pipe; the small adaption pipe is arranged in the large adaption pipe; axes of the two adaption pipes are positioned on the same line; the bottom ends of the two adaption pipes are connected to the same bottom plate; the height of the large adaption pipe is larger than that of the small adaption pipe; the top of the large adaption pipe is provided with a flange; the flange is connected with the fluidization air pipeline; a side wall of the lower part of the large adaption pipe is provided with fluidization holes; two rows of fluidization holes of the concentrated phase bilge pump fluidization nozzle are arranged on the side wall of the lower part of the large adaption pipe and are distributed on the circumference of the side wall. The concentrated phase bilge pump fluidization nozzle is good in fluidization effect, simple in manufacturing process, low in cost, wear-resistant and long in service life.
Description
Technical field
The utility model relates to the fluidisation nozzle that a kind of dry ash removal system uses, and particularly discloses a kind of concentrated phase storehouse pump fluidisation nozzle, is applied in the malleation dense Phase Pneumatic Ash Handling system of thermal power plant.
Background technology
Malleation dense Phase Pneumatic Ash Handling system is the comparatively emerging dry ash removal system of China, be widely used the storehouse pump and carry at a distance lime-ash in the flue gas, have system succinct, flexible arrangement, reliable, degree of automation is high, system's reduced investment carries grey gas than high, and flow velocity is low, the characteristics such as the little and annual operating cost of maintenance workload is low, this system is widely used at home.
Malleation dense Phase Pneumatic Ash Handling system changes very much and the development of Dual-Phrase Distribution of Gas olid technology in conjunction with stream, the mode convey materials that storehouse pump (transmitter) is carried with limit fluidisation, limit.Therefore for dense phase pneumatic conveying system, the fluidized state in the pump of storehouse is extremely important to normal feeding and the conveying of storehouse pump.
Conventional gasification installation, such as canvas type multilayer gasification installation, and carborundum formula gasification installation has the easy putty of hole, resistance is large, the various shortcomings such as cracky, at present modal tower gasification board also exists material easily to enter air chamber, and returning charge is to shortcomings such as airline and gasification board are easy to wear.This kind equipment for a change domestic pneumatic ash handling in a difficult problem of carrying very poor coal operating mode to run into, domestic pneumatic ash handling producer employed storehouse pump (transmitter) is owing to lacking the actv. fluidizer, cause can't accomplishing to adapt to large ash amount, exert oneself under the operating mode greatly, system is smooth operation normally.
Summary of the invention
The purpose of this utility model is to solve the prior art nozzle easily to block up, the maintenance trouble, the shortcoming that the repair and maintenance work capacity is large, disclose a kind of concentrated phase storehouse pump fluidisation nozzle, the structure of nozzle is improved, break through the version of the common ventilative material gasification board of tradition, fluidization was even when nozzle used, and effect is good, and drag losses is low, and the repair and maintenance work capacity is little.
The utility model is achieved in that a kind of concentrated phase storehouse pump fluidisation nozzle, comprise storehouse pump (transmitter), fluidized wind pipeline, it is characterized in that: the fluidized wind pipe head in the pump of described storehouse connects the fluidisation nozzle, described fluidisation nozzle arrangements is provided with large adapter and small takeover, small takeover is arranged in the large adapter, and both axis are on the same straight line, the bottom is connected on the same base plate, large height of nozzle is greater than small takeover, the large top of taking over is provided with flange, be connected with the fluidized wind pipeline by flange, take over greatly lower sides and be provided with the fluidisation hole.The fluidisation hole of described concentrated phase storehouse pump fluidisation nozzle is provided with two rows at the large lower sides of taking over, and is distributed on the sidewall circumference.
Two rounds directly in the uniform perforate of large adapter lower part of nozzle, are generally opened in the fluidisation hole of nozzle of the present utility model, make fully uniform fluidisation of grey gas.At the small takeover that the large inside of taking over is set up, can prevent that ash from entering that large adapter is laggard to enter the fluidized wind pipeline.
The beneficial effects of the utility model are: the utility model concentrated phase storehouse pump fluidisation nozzle adopts flange form to connect, and can be firm be connected with the fluidized wind pipeline increased stability and the fastness of nozzle.The utility model concentrated phase storehouse pump fluidisation nozzle fluidisation is effective, and manufacture craft is simple, and cost is low, and is wear-resistant, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, flange; 2, the large adapter; 3, small takeover; 4, fluidisation hole; 5, base plate.
The specific embodiment
With reference to the accompanying drawings, a kind of concentrated phase of the utility model storehouse pump fluidisation nozzle comprises storehouse pump (transmitter), fluidized wind pipeline.Fluidized wind pipe head in the pump of storehouse connects the fluidisation nozzle, the fluidisation nozzle arrangements is for being provided with large adapter 2 and small takeover 3, small takeover 3 is arranged in the large adapter 2, and both axis are on the same straight line, the bottom is connected on the same base plate 5, takes over greatly 2 height greater than small takeover 3, takes over greatly 2 tops and is provided with flange 1, be connected with the fluidized wind pipeline by flange 1, take over greatly 2 lower sides and be provided with fluidisation hole 4.The fluidisation hole 4 of concentrated phase storehouse pump fluidisation nozzle is provided with two rows at large 2 lower sides of taking over, and is distributed on the sidewall circumference.
The utility model is used for strength and carries malleation dense Phase Pneumatic Ash Handling system, and the bulk granular material of noncohesive drying need be less than 2mm, and water ratio is less than 2%, and drag losses is less than 2Kpa behind use the utility model.
The utility model is by 20
#Steel making adopts flange to connect, and fluidized wind pipeline operation pressure all can be suitable between 0.01～0.8MPa.
