Abstract
The utility model relates to a kind of flue gas flow equalizing distributor, is made up of the isocon of base tube and multiple same volume, and base tube open area is each isocon sectorial area sum; Isocon one end is fan-shaped port, and one end is circular port, and two port areas are equal; Rounding off between fan-shaped port and circular port, each isocon entirety is 90 degree of elbow shapes, and each circular port bends towards outside base tube.The angle that isocon forms fan-shaped port is 360/n degree, and wherein n is isocon number, 2≤n≤8, and scalloped end port radius is equal with base tube radius.Compared with traditional smoke distributor, flue gas flow equalizing distributor flue gas distributed uniform described in the utility model, local resistance loss is less, avoid flue gas fluid diversion procedure to form whirlpool dead band and the flue gas that causes and distribute the problems such as uneven, noise and vibration, thus extend the cycle of operation of boiler.Flue gas distributed uniform, improves residual neat recovering system efficiency, convenient operating maintenance.
Description
Technical field
The utility model relates to a kind of fluid current equalizer, specifically a kind of flue gas flow equalizing distributor.
Background technology
In boiler afterheat recovery technology field, usually need by boiler discharge high-temperature flue gas carry out equal flow assignment laggard enter parallel waste-heat recoverer or waste heat recovery tube bank.Existing flue gas flow equalizing device adopts static-pressure box type mostly, and flue gas shunting process exists flow dead, and cause flue gas long in the dispensing section time of staying, smoke flow resistance is larger.In addition, because the existence in eddy current and dead band can cause shunting section to there is low-frequency noise, flue gas also can be caused to distribute uneven phenomenon, reduce the utilization ratio of waste heat recovery heat-exchange system.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of flue gas flow equalizing distributor.
Concrete technical scheme is as follows:
A kind of flue gas flow equalizing distributor is made up of the isocon of base tube and multiple same volume, and base tube open area is each isocon sectorial area sum; Isocon one end is fan-shaped port, and one end is circular port, and two port areas are equal; Rounding off between fan-shaped port and circular port, each isocon entirety is 90 degree of elbow shapes, and each circular port bends towards outside base tube.
The angle that isocon forms fan-shaped port is 360/n degree, and wherein n is isocon number, 2≤n≤8, and scalloped end port radius is equal with base tube radius.
Wherein more preferably, isocon height is not more than base tube diameter;
Wherein more preferably, flue gas flow equalizing distributor monoblock cast processing.
Compared with prior art, the beneficial effects of the utility model are: compared with traditional smoke distributor, flue gas flow equalizing distributor flue gas distributed uniform described in the utility model, local resistance loss is less, avoid flue gas fluid diversion procedure to form whirlpool dead band and the flue gas that causes and distribute the problems such as uneven, noise and vibration, thus extend the cycle of operation of boiler.Flue gas distributed uniform, improves residual neat recovering system efficiency, convenient operating maintenance.

Detailed description of the invention
Be described in further details the utility model below in conjunction with the drawings and specific embodiments, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment one: as shown in FIG. 1 to 3, a kind of flue gas flow equalizing distributor is made up of base tube 1 and four isocons 2.Isocon entirety is 90 degree of elbow shapes, and wherein one end is 90 degree of fan-shaped ports, and scalloped end port radius is equal with base tube radius; The other end is the circular port that area is equal with fan-shaped port, rounding off between two-port.The fan-shaped port of four isocons is coaxially connected with base tube 1, and adjacent fan-shaped port sidewall is connected with each other; The height of isocon equals base tube radius; Flue gas flow equalizing distributor entirety adopts casting processing.
Embodiment two: as shown in Fig. 4 ~ Fig. 6, a kind of flue gas flow equalizing distributor is made up of base tube 1 and eight isocons 2.Isocon entirety is 90 degree of elbow shapes, and wherein one end is 45 degree of fan-shaped ports, and scalloped end port radius is equal with base tube radius; The other end is the circular port that area is equal with fan-shaped port, rounding off between two-port.The fan-shaped port of eight isocons is coaxially connected with base tube 1, and adjacent fan-shaped port sidewall is connected with each other; The height of isocon equals base tube radius; Flue gas flow equalizing distributor entirety adopts casting processing.
Flue gas flow equalizing distributor flue gas distributed uniform described in the utility model, local resistance loss is less, avoid flue gas that the whirlpool dead band that formed in flue gas shunting process causes and distribute the problems such as uneven, noise and vibration, flue gas distributed uniform, improve the utilization ratio of flue gas waste heat recovery system, extend the cycle of operation of waste-heat recovery device, Operation and Maintenance is more convenient.
Although be described the utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; when not departing from the utility model aim, can also make a lot of distortion, these all belong to protection domain of the present utility model.
