Description

Integrated evaporation ventilation window and gas-gas heat exchange type dehumidification dryer

Technical Field

The utility model relates to an air source heat pump dryer, in particular to an integrated evaporation ventilation window and air-air heat exchange type dehumidification dryer.

Background

In daily life, occasions needing dehumidification, such as indoor air conditioners in summer, rainy seasons, basements, wine cellars and the like, and occasions needing constant humidity in pharmacy, electronic workshops and other processes are more strict in requirements. The air dehumidification method comprises ventilation dehumidification, temperature rise dehumidification, freezing dehumidification, solution dehumidification, solid dehumidification, dry dehumidification and the like, and mixed dehumidification combining the dehumidification methods.

The temperature rise dehumidification is that air is heated by a heater to rise temperature, and when the temperature of the air rises while keeping the absolute moisture content constant, the relative humidity is reduced. The temperature rise dehumidification is simple and easy to implement, the investment and the operation cost are not high, but the air temperature is raised and the air is not fresh while dehumidification is carried out, so that the method is suitable for occasions without requirements on the indoor temperature.

The refrigeration dehumidification is to cool air by a cold surface to reduce the temperature, and when the temperature of the air is reduced to be lower than a dew point, water vapor in the air is condensed and separated out. The refrigeration and dehumidification performance is stable, the work is reliable, the continuous work can be realized, but cold water is provided by refrigeration, the equipment cost and the operation cost are high, and the noise is generated; because of the limitation of cold water temperature and cooling efficiency, the method is suitable for occasions with dew point temperature higher than 4 ℃.

Solution dehumidification utilizes the difference between the water vapor partial pressure of air and the saturated vapor pressure on the surface of dehumidification solution to carry out mass transfer, low-temperature dehumidification solution is used for absorbing moisture in high-temperature humid air during dehumidification, the dehumidification solution is heated and heated during regeneration, and the moisture is discharged after the dehumidification solution is contacted with relatively low-temperature and dry air. The solution has good dehumidification effect, can continuously work, has the function of cleaning air, but has more complex equipment, high initial investment, needs a heat source during regeneration and has large cooling water consumption. The solution dehumidification is suitable for occasions with large dehumidification capacity, indoor sensible heat ratio less than 60 percent and air outlet dew point temperature lower than 5 ℃.

The dehumidification of the solid material utilizes the capillary action of the surface of some solid materials or the steam partial pressure difference during phase change to adsorb or absorb the moisture in the air. The solid dehumidification equipment is simple, the investment and the operation cost are low, but the dehumidification performance is not stable, and is reduced along with the increase of time, regeneration is needed, and the method is suitable for occasions with small dehumidification capacity and the dew point temperature required to be lower than 4 ℃. Commonly used absorbent solid adsorbents: the anhydrous calcium chloride CaCl2 is a white porous crystal, has strong moisture absorption capacity, and is deliquesced after moisture absorption to become a calcium chloride solution. The purity of the commonly used industrial calcium chloride is 70 percent, and the moisture absorption amount can reach 100 percent of the self mass; phosphorus pentoxide P2O5, also known as phosphoric anhydride, white soft powder; sodium hydroxide NaOH, also known as caustic soda, is a colorless and transparent crystal; copper sulfate, CuSO4.5H2O is commonly called blue vitriol, blue triclinic system crystal, when heated to 250 ℃, all crystal water is lost, and the crystal becomes green white powder. Common adsorptive solid desiccant: the silica gel SiO2 is a non-toxic, odorless and non-corrosive semitransparent crystal, is insoluble in water, has a porosity of up to 70 percent, and can be regenerated by hot air at 150-180 ℃ after moisture absorption; the molecular sieve has a uniform microporous structure and can separate molecules with different sizes; activated carbon is a carbon with a porous structure and a strong adsorption capacity for gases, vapors or colloidal solids, and is usually made of organic materials such as wood, fruit stones, etc. by special processing, and the carbon content can reach as high as 98%.

The dry dehumidification is also solid dehumidification in fact, and the moisture in the air is absorbed or adsorbed by a carrier processed by a moisture absorption material, such as a lithium chloride rotating wheel, under the action of the difference of the moisture and the pressure of the steam. The dry type dehumidification device has the advantages of large dehumidification and moisture absorption area, stable performance, continuous dehumidification, adjustable humidity, large dehumidification amount, full-automatic operation, complex equipment and regeneration. The dry type dehumidification has wide applicable temperature range, and can effectively dehumidify within the range of minus 30 to 40 ℃; as the temperature decreases, the crystal water that lithium chloride can contain increases, and thus, a good dehumidification effect is obtained in a low-temperature and low-humidity state. Lithium chloride rotary wheel dehumidification is the most typical dry dehumidification, lithium chloride absorbs moisture in air to form crystal water, and does not change into aqueous solution, namely the dry dehumidification does not generate corrosion of the aqueous solution to equipment, and a dehumidifying agent does not need to be added and supplemented, so that the lithium chloride rotary wheel dehumidification is ideal dehumidification equipment.

The working principle of lithium chloride rotary wheel dehumidification is as follows: the rotating wheel loaded with the moisture absorbent is divided into a working area and a regeneration area. At normal temperature, when air to be treated flows through the working area, moisture in the air is adsorbed by the moisture absorbent and then is sent out; the regeneration air flows through the regeneration area of the rotating wheel after being heated, and the moisture in the moisture absorbent is discharged after being desorbed.

The ventilation and dehumidification is the window ventilation, on one hand, dry air is introduced from the outside, and meanwhile, relatively humid air is discharged to the outside, so that the indoor humidity is reduced in a replacement and mixing manner. The ventilation dehumidification does not need any consumption, is economic and simple, but requires dry outdoor air and is influenced by wind direction and wind power, so the guarantee rate is low; besides humidity, various indoor and outdoor mixtures such as temperature and the like exist, and the method is suitable for occasions with less strict indoor requirements.

Therefore, different dehumidification methods have respective obvious advantages and disadvantages, so that the utility model combines the advantages and disadvantages of the dehumidification methods. For the application occasions requiring certain air quality and large-batch dehumidification in the dehumidification process, the efficiency of the whole dryer needs to be improved as much as possible, and the safety is ensured. The above single modes cannot well meet the requirement.
