除尘系统中通风管道设计中一般要注意三个问题，接下来由济南顺发通风管道工程公司的小编为大家详细讲解一下。

In the design of ventilation duct in dust removal system, three problems should be paid attention to. Next, Jinan Shunfa Ventilation Pipe Engineering Company will explain them in detail.

通风管道注意问题

Attention to ventilation ducts

1、管道构件

1. Piping components

弯头弯头是联接管道的常见构件，其阻力大小与弯管直径d、曲率半径R以及弯管所分的节数等要素有关。曲率半径R越大，阻力越小。但当R大于2～2.5d时，弯管阻力不再显着下降，而占用的空间则过大,使系统管道、部件及设备不易安顿，故从有用动身，在规划中R一般取1～2d，90°弯头一般分红4～6节。

Elbow elbow is a common component of connecting pipeline. Its resistance is related to the diameter d, curvature radius R and the number of segments of the elbow. The larger the radius of curvature R, the smaller the resistance. However, when R is greater than 2-2.5 days, the elbow resistance will no longer decrease significantly, but the space occupied is too large, so that the system pipes, components and equipment are not easy to settle down. Therefore, starting from useful, R is generally taken 1-2 days in the planning, and 90 degrees elbow is generally divided into 4-6 sections.

2、管道配件

2, pipe fittings

调度阀门集中式除尘系统阻力不平衡的情况在运转中是难免的，因此，在与吸尘罩联接的垂直管段上设调度阀门。

It is unavoidable that the resistance of centralized dust removal system of dispatching valve is unbalanced in operation. Therefore, a dispatching valve is arranged on the vertical pipe section connected with the dust cover.

常见的调度阀门有蝶阀斜插板阀等，在吸入段管道上，一般不容许选用直插板阀，因为它简略引起管道堵塞。作为调度风量用。

Common dispatching valves have butterfly valve diagonal valve, etc., in the suction section of the pipeline, generally do not allow the use of straight-plug valve, because it simply causes pipe jam. For dispatching air volume.

无论是斜插板或蝶阀，都必须装设在垂直管段上。因为阀板前后发作剧烈的涡旋，粉尘很简略堆积，假设这类阀板装在斜管或水平管段上，堆积粉尘还会阻碍阀板的开关或堵塞管道。

Both inclined plates or butterfly valves must be installed on vertical pipes. Dust accumulates briefly because of the violent whirlpools around the disc. Assuming that the disc is mounted on a sloping or horizontal pipe section, the accumulation of dust can also hinder the disc from switching or blocking the pipe.

3、管道安顿

3, pipeline settlement

(1) 管道安顿力求简略，尽可能垂直或歪斜装设，歪斜角一般不得小于50°，使管道内的积尘能天然滑下。

(1) The installation of the pipeline should be as simple as possible, and the inclination angle should not be less than 50 degrees, so that the dust in the pipeline can slide down naturally.

(2) 分支管与水平管或主干管联接时，一般从管道的上面或周围面接入。

(2) when a branch pipe is connected with a horizontal pipe or a main pipe, it is usually connected from the top or the surrounding surface of the pipeline.

(3) 管道一般选用圆形截面，因为方形、矩形截面管道四角会发作涡流，易积粉尘。较小直径一般不小于100mm，以防管道堵塞。

(3) Round cross-section is generally used in the pipeline, because the square and rectangular cross-section of the pipeline will produce eddy current, easy to accumulate dust. The minimum diameter is generally less than 100mm, so as to prevent pipe blockage.

(4) 管道不宜支承在设备上，应设支、吊架。钢制管道水平设备时，其固定件的距离，当管径不逾越360mm时，不大于4m;逾越360mm时，不大于3m。当垂直设备时，其固定件的距离不大于4m，拉绳和吊架不允许直接固定在法兰盘上。

(4) piping should not be supported on equipment, and supports and hangers should be set up. When the pipe diameter is not more than 360mm, the distance between the fixtures is not more than 4m for the horizontal equipment of steel pipeline, but not more than 3m for the horizontal equipment of steel pipeline. When the vertical equipment, the distance between the fixtures is not more than 4m, the pulling rope and the hanger are not allowed to be directly fixed on the flange plate.

(5) 为减轻风机的磨损，宜将除尘器设备置于风机之前。以上是管道规划应留意的几个问题。在实践规划中，管道的直径、风速和流量，还要根据实践情况进行阻力核算，在确保运用作用的前提下，使输运气流的能耗较小。

(5) in order to reduce the wear of the fan, the dust collector should be placed before the fan. Above are some problems that should be paid attention to in pipeline planning. In practical planning, the pipe diameter, wind speed and flow, but also according to the practice of resistance accounting, in order to ensure the use of the premise, so that the transport of air energy consumption minimum.

通风管道正确的清洁办法?通风管道清洗主张每半年清洗一次。其可根据其用途的不同

The correct cleaning method for ventilation pipes? Ventilation pipe cleaning is advocated once every six months. It can be used for different purposes.

清洗时刻也是纷歧的，那么通风管道的正确清洗办法有那些呢?

Cleaning time is also different. So what are the correct cleaning methods for ventilation ducts?

1、开孔法：此办法较拆开法而言相对简略，费用相对较低，但清洗作 用也相对有必定距离。

1. Opening method: This method is relatively simple compared with opening method, the cost is relatively low, but the cleaning effect also has a certain distance.

2、拆开法：此办法是较完全、清洗作用较好的清洗办法，但施工难度大，工人量也大，一同费用也相对较高。

2. Dismantling method: This method is the most complete and the best cleaning method, but the construction is difficult, the workload is also large, and the cost is relatively high.

具体办法是：由技能职工测算出需求开孔的距离距离、开 孔方位、大小和数目，经过这些孔对通风管道内进行通风管道清洗。毕竟对每个孔进行密封处理。

The specific method is: the skilled workers measure the distance, orientation, size and number of the required openings, through which the ventilation duct is cleaned. After all, seal each hole.

3、机械设备法：此办法较简略操作、 难度较小、工作量较小、费用较低的通风管道清洗办法，但清洗作用一同也是较差的，但关于清洗周期为半年以下的竖通风管道清洗，这种清洗办法无疑是较好的挑选。

3. Mechanical equipment method: This method is the simplest operation, the least difficult, the least workload, the lowest cost of ventilation duct cleaning method, but the cleaning effect is also the worst, but about the cleaning cycle of less than six months of vertical ventilation duct cleaning, this cleaning method is undoubtedly the best choice.

具体的办法是：向通风管道内喷洒化油剂后，用能够伸入通风管道内长达30米的电动 软轴刷和气动软轴刷对重庆通风管道内壁进行清洗。

The specific method is: after spraying the carburant into the ventilation duct, the inner wall of Chongqing ventilation duct is cleaned with the electric soft-shaft brush and the pneumatic soft-shaft brush which can reach 30 meters into the ventilation duct.
