部分送风向部分作业地址送风,使部分地带形成良好的空气环境。关于面积很大,操作人员较少的出产车间,用全面通风的办法改进整个车间的空气环境,既困难又不经济,同时也是不必要的。

Part of the air supply direction and part of the work address air supply, so that part of the formation of a good air environment. It is not only difficult but also inexpensive to improve the air environment of a workshop with a large area and fewer operators by means of comprehensive ventilation.

例如某些高温车间,没有必要对整个车间进行降温,只需向单个的部分作业地址送风,在部分地址形成良好的空气环境,这种通风办法称为部分送风。

For example, in some high-temperature workshops, there is no need to cool the whole workshop, only to supply air to a single part of the work address, forming a good air environment in some locations. This ventilation method is called partial air supply.

部分送风主要用于部分降温,又分为体系式和涣散式两种。下面小编来给我们具体介绍一下通风管道部分送风的作业办法

Partial air supply is mainly used for partial cooling, which can be divided into two types: system type and scattered type. Below is a small series to give us a specific introduction to the ventilation duct part of the air supply method of operation.

1。体系式送风体系体系式就是通风设备将室外空气送至作业地址。空气经集中处理后送入部分作业区。涣散式部分送风一般运用轴流电扇或喷雾电扇,选用室内再循环空气。

1. Systematic air supply system is that ventilation equipment delivers outdoor air to the working address. After centralized treatment, the air is sent to some working areas. Slack type partial air supply usually uses axial fan or spray fan to select indoor recirculating air.

2.涣散式送风体系涣散式凭借轴流电扇或喷雾电扇,直接将室内空气吹向作业地带进行循环通风。

2. the slack air supply system is slack type, which uses axial fan or spray fan to directly blow indoor air into the working area to circulate ventilation.

(1)电扇送风在作业点附近设置一般轴流风机进行循环吹风,加速对流散热。作业点风速要求:①轻作业——2~4m/s;②中作业——3~5m/s;③重作业——5~7m/s。适用于气温不大于35℃,且非产尘的车间。

(1) A general axial-flow fan is installed near the operating point for circulating air to accelerate convective heat dissipation。 The requirements of wind speed at work points are as follows: 1) light work - 2-4m/s; 2) medium work - 3-5m/s; and 3) heavy work - 5-7m/s。 Suitable for workshop with temperature not more than 35 C and non-dust production。

(2)喷雾电扇送风喷雾电扇是在通风机上装有喷雾装置的部分送风设备,即在一般轴流风机上加设甩水盘构成喷雾电扇送风具有降温作用,雾洒落在人体表面又能促进人体蒸发散热,悬浮在空气中的小雾滴还能吸收热辐射,减轻人体受热辐射的影响。

(2) spray fan spray fan is part of the air supply equipment equipped with spray device on the fan, that is, add a water throwing plate on the general axial fan, and the spray fan has the cooling effect。 The fog falls on the surface of the human body and promotes the evaporation and heat dissipation of the human body。 The small droplets suspended in the air can absorb heat radiation and reduce the influence of the body's heating radiation。

但也会引起人工汗。要求:要求喷雾电扇应有满足的风量、喷雾量和射程;喷雾的水滴<60μm,最大不超越100μm。风速不大于3~5m/s。

But it can also cause artificial sweat. Requirements: spray fans should be satisfied with the air volume, spray volume and range; the spray droplet is <60 and m, and the maximum does not exceed 100 m. The wind speed is not more than 3-5 m/s.

通风管道部分送风主要应用在:喷雾电扇适用于高温、强热辐射的作业地址。用于温度高于35℃,辐射强度大于1400W/m2,细微雾滴对出产工艺无影响的中、重作业点。

The partial ventilation of ventilation pipes is mainly applied to: the spray fans are suitable for high temperature and strong heat radiation。 It is used at medium and heavy operation points where the temperature is higher than 35 C and the radiation intensity is greater than 1400W/m2, and the fine mist droplets have no effect on the production process。
