Problems solved by technology

In the actual use process, the air inlet end of the wet curtain is cold and the humidity is high, and the air outlet end of the fan is hot and the humidity drops
The temperature difference in the workshop is large, and the humidity is difficult to control; in winter, it is difficult to keep warm and humidify, etc.
The emergence of these problems is not conducive to the promotion of this energy-saving technology in the textile industry

Embodiment 1

[0082] An enterprise in Xijiang has 192 air-jet weaving machines, with an installed power of 4kw per machine. The workshop is a steel structure factory building, surrounded by attached buildings. The workshop is 62m wide and 72.8m long. Workshop area 4613.6m 2 , roof slope 0.065. Outdoor design dry bulb temperature t n is 32°C. The relative humidity is 75%, and there are 18 people per shift in the workshop. Since there are attached rooms around the workshop,

[0083] Therefore, the heat input from the wall can be ignored, and only the heat input from the roof is considered. The roof is made of color steel tiles with a 10cm insulation layer, and the heat transfer coefficient is 0.43W / (m 2 ·°C).

[0084] Among them, cooling load calculation:

[0085] The heat Q transmitted from the enclosure structure into the room w =kF(t w -t n )=0.43×4513.6×4=7763.4W;

[0086] The incoming heat Q of solar radiation F =0.0404kF'ρJα=0.0404×0.43×4513.6×1058×0.5=41479W;

Abstract

The invention provides a novel wet curtain energy-saving textile mill air-conditioning system which comprises wet curtains, a main air duct, a wet curtain clerestory, a forced draft blower, an air feeding duct, an exhausting duct and a dust filter unit. The wet curtains are of honeycomb structures formed by stacking corrugated paper layers and are respectively arranged on two sides of the wet curtain clerestory, the wet curtain clerestory is arranged above the main air duct, the main air duct is communicated with the wet curtains and horizontally communicated with the air feeding duct, the forced draft blower is arranged at the position of an air inlet of the air feeding duct, the air feeding duct is arranged at the upper portion of a production workshop, the exhausting duct is arranged at the lower portion of the production workshop, and the dust filter unit is arranged at the air outlet end position of the exhausting duct. A 'side feeding and side exhausting' air supplying mode of the system is changed into an 'upward supplying and downward exhausting' mode, is combined with a textile mill air conditioner, and accordingly temperature reduction in summer, humidification in winter and temperature and humidity control of the workshop can be achieved well.

Description

technical field [0001] The invention relates to a textile air-conditioning system, in particular to a novel wet curtain energy-saving textile air-conditioning system. Background technique [0002] Cooling in summer is the season with the highest energy consumption of textile air conditioners. In the form of textile air conditioners widely used at present, in order to control the relative humidity of the workshop and lower the temperature in summer, only low-temperature water can be used. A large amount of groundwater or electricity (electric refrigeration) will be consumed. Applying the wet curtain fan cooling system to the textile air conditioning system can not only save this part of energy and resources, but also improve the freshness and comfort of the air in the workshop. [0003] The so-called wet curtain fan cooling system is composed of a wet curtain 1, a water circulation system, an axial flow fan 3 and an electric control device. The wet curtain 1 is made of cor...
