除塵系統(tǒng)中通風管道設計中一般要注意三個問題，接下來由濟南順發(fā)通風管道工程公司的小編為大家詳細講解一下。

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.

通風管道注意問題

Attention to ventilation ducts

1、管道構件

1. Piping components

彎頭彎頭是聯(lián)接管道的常見構件，其阻力大小與彎管直徑d、曲率半徑R以及彎管所分的節(jié)數(shù)等要素有關。曲率半徑R越大，阻力越小。但當R大于2～2.5d時，彎管阻力不再顯著下降，而占用的空間則過大,使系統(tǒng)管道、部件及設備不易安頓，故從有用動身，在規(guī)劃中R一般取1～2d，90°彎頭一般分紅4～6節(jié)。

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

調度閥門集中式除塵系統(tǒng)阻力不平衡的情況在運轉中是難免的，因此，在與吸塵罩聯(lián)接的垂直管段上設調度閥門。

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.

常見的調度閥門有蝶閥斜插板閥等，在吸入段管道上，一般不容許選用直插板閥，因為它簡略引起管道堵塞。作為調度風量用。

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.

無論是斜插板或蝶閥，都必須裝設在垂直管段上。因為閥板前后發(fā)作劇烈的渦旋，粉塵很簡略堆積，假設這類閥板裝在斜管或水平管段上，堆積粉塵還會阻礙閥板的開關或堵塞管道。

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、管道安頓

3, pipeline settlement

(1) 管道安頓力求簡略，盡可能垂直或歪斜裝設，歪斜角一般不得小于50°，使管道內的積塵能天然滑下。

(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) 分支管與水平管或主干管聯(lián)接時，一般從管道的上面或周圍面接入。

(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) 管道一般選用圓形截面，因為方形、矩形截面管道四角會發(fā)作渦流，易積粉塵。較小直徑一般不小于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) 管道不宜支承在設備上，應設支、吊架。鋼制管道水平設備時，其固定件的距離，當管徑不逾越360mm時，不大于4m;逾越360mm時，不大于3m。當垂直設備時，其固定件的距離不大于4m，拉繩和吊架不允許直接固定在法蘭盤上。

(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) 為減輕風機的磨損，宜將除塵器設備置于風機之前。以上是管道規(guī)劃應留意的幾個問題。在實踐規(guī)劃中，管道的直徑、風速和流量，還要根據(jù)實踐情況進行阻力核算，在確保運用作用的前提下，使輸運氣流的能耗較小。

(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.

通風管道正確的清潔辦法?通風管道清洗主張每半年清洗一次。其可根據(jù)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.

清洗時刻也是紛歧的，那么通風管道的正確清洗辦法有那些呢?

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

1、開孔法：此辦法較拆開法而言相對簡略，費用相對較低，但清洗作 用也相對有必定距離。

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、拆開法：此辦法是較完全、清洗作用較好的清洗辦法，但施工難度大，工人量也大，一同費用也相對較高。

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.

具體辦法是：由技能職工測算出需求開孔的距離距離、開 孔方位、大小和數(shù)目，經(jīng)過這些孔對通風管道內進行通風管道清洗。畢竟對每個孔進行密封處理。

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、機械設備法：此辦法較簡略操作、 難度較小、工作量較小、費用較低的通風管道清洗辦法，但清洗作用一同也是較差的，但關于清洗周期為半年以下的豎通風管道清洗，這種清洗辦法無疑是較好的挑選。

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.

具體的辦法是：向通風管道內噴灑化油劑后，用能夠伸入通風管道內長達30米的電動 軟軸刷和氣動軟軸刷對重慶通風管道內壁進行清洗。

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.
