Technical Field

The utility model relates to a be used for static absorbent heat-retaining device, especially relate to a magnetic particle multilayer structure heat-retaining device for static absorption.

Background

In many industrial processes, harmful gases are often generated, and most of the gases contain organic substances which threaten human health, such as toluene, xylene, ethyl acetate, butyl acetate and the like. In the treatment of these gases, adsorption is often carried out using suitable adsorbent materials, and the adsorption effect of such materials is examined by static adsorption experiments.

Static adsorption experiments are adsorption methods corresponding to dynamic adsorption. Static adsorption experiments refer to the use of a specified amount of an adsorbent material and a fixed amount of solution, followed by a long period of sufficient contact to reach equilibrium. The static adsorption equilibrium determination method comprises the following steps: (1) volumetric method of measuring the gas volume reduction value after a period of adsorption while keeping the pressure of the gas phase constant; (2) a gravimetric method of determining the weight gain of the adsorbent by contacting the adsorbent with a gas; (3) the magnitude of the change in gas pressure (volume unchanged) or solution concentration change was determined. Static adsorption experiments are typically performed in a negative pressure environment, which ensures that the boiling point of the solution is below the boiling point of normal atmospheric pressure. When the corresponding temperature condition is reached, the solution can be quickly vaporized to fill the whole vacuum drying dish, so that the absorption of the adsorption material is facilitated. The existing static adsorption heat storage device is a flat plate supporting plate generally, a tray for containing a solvent needs to be heated in advance during use, the solvent is injected after vacuumizing is finished, and the solvent is dripped into the tray at the moment, so that the solvent can be rapidly vaporized and volatilized because the temperature of the tray is higher than the theoretical boiling point temperature of the solvent. However, the heat source of the method is only the tray, the heat source is single, and the effective contact area is small.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1 and 2, in the heat storage device with a magnetic particle multilayer structure for static adsorption according to the present embodiment, an open rectangular box-shaped container 1 made of an aluminum alloy material is selected, and the size of the container 1 is generally 6 to 8cm in length, 4 to 5cm in width, and 2.5 to 3cm in height. In this example, the length of the inside of the container 1 is 6cm, the width thereof is 4cm, and the height thereof is 3 cm. Through holes 1a are formed in the bottom of the open rectangular container 1 in a matrix arrangement mode, and the diameter of each through hole 1a is slightly smaller than that of each first magnetic sphere 2. The first magnetic ball 2 is made of neodymium iron boron magnetic material, the first magnetic ball 2 with the diameter of 1cm is placed at the position where the through hole 1a is drilled, and at the moment, the first magnetic ball 2 protrudes downwards out of the bottom surface of the container 1. A magnetic sphere layer composed of the same magnetic spheres 2 is laid above the first magnetic sphere 2, and the magnetic sphere 2 is made of neodymium iron boron permanent magnet and has large magnetism, so that the connection between the magnetic sphere 2 and the first magnetic sphere 1 is very tight and is not easy to slide or generate a fault phenomenon.

The device is put into an oven to be heated and kept at a preset temperature (considering that the device loses part of heat when being taken out of the oven, so the preset temperature is slightly higher than the theoretical boiling point of a solvent), the expansion coefficient of the first magnetic sphere 2 is larger than that of the aluminum alloy open rectangular container 1, so the first magnetic sphere 2 is in interference fit with the through hole 1a on the bottom surface of the open rectangular container 1 during heating and is not easy to fall off, the first magnetic sphere is quickly put into a vacuum drying dish after being taken out, then an acrylic plate is covered on the vacuum drying dish to be vacuumized, the vacuumization is stopped when the pressure in the vacuum drying dish reaches a preset negative pressure condition, the solvent is injected to drop into the heat source device, and at the moment, the solvent firstly contacts the magnetic sphere, then contacts the bottom of the device and absorbs heat from the magnetic sphere and the. Because gaps exist among the magnetic spheres, the whole structure is porous, so that the contact area with the solvent is increased, the number of heat sources is large, and the solvent is effectively ensured to absorb sufficient heat to volatilize. After the experiment is finished and the temperature is cooled to the room temperature, the first magnetic sphere 2 contracts and can be conveniently taken out from the open rectangular container 1, and the cleaning is convenient.
