Description

Evaporation device and dual-mode evaporation device

Technical Field

The utility model relates to a disinfection evaporation technology field, more specifically relates to an evaporation plant and double mode evaporation plant.

Background

The frequent occurrence of various air pollution events has caused air cleaning equipment with the capability of killing bacteria and viruses to be of great interest. The indoor air and goods sterilizing equipment on the market at present can be divided into air sterilizing machines depending on physical factors and chemical factors. The physical factor sterilizer utilizes electrostatic adsorption, filtration technology, ultraviolet rays and other methods to kill or remove microorganisms, such as an air purifier (based on high-efficiency air filtration HEPA or electrostatic dust collection), an ultraviolet ray disinfection device and the like. The chemical factor sterilizer uses the generated chemical factors to kill microorganisms, such as an ozone sterilizer and a hydrogen peroxide dry fog sterilizer.

The main part of the air purifier in the market is HEPA composite filter screen or electrostatic precipitator, most products do not contain special modules for disinfection and sterilization, microorganisms in the air are removed only through a filtering technology, the microorganisms are not killed (the survival time of certain bacteria and viruses on the surface of a dry inanimate object can be up to 2-16 months), and the risk of secondary release exists. The ultraviolet disinfection is sterilization through the action of light wave radiation, the disinfection effect is related to the irradiation position and the irradiation intensity, and the ultraviolet disinfection can only be used under the unmanned condition because the ultraviolet is harmful to human bodies. Ozone disinfection is mainly to convert oxygen in air into ozone through an ozone generator and release the ozone to a space needing to be purified so as to play a role in killing bacteria, but ozone has strong stimulation, the ozone concentration needs to be more than 10ppm (higher than the safety limit value which can be borne by ordinary people by 0.1 ppm) during disinfection, and the ozone disinfection needs to be carried out under the closed and unmanned condition during use. The hydrogen peroxide disinfection machine atomizes high-concentration hydrogen peroxide solution into fog drops smaller than 10 mu m by an ultrasonic atomization method and a mechanical atomization method, and the fog drops are uniformly released into a target disinfection space. The purification efficiency of the similar technology is high, but hydrogen peroxide vapor with the concentration of 200-1000 ppm needs to be released in the target disinfection space, so that personnel can not enter the target disinfection space during disinfection, and ventilation is needed until the hydrogen peroxide concentration is lower than 1ppm after disinfection.

The material of the evaporation fabric is a material which is resistant to the corrosion of the disinfectant.

Next, a dual-mode evaporation apparatus according to an embodiment of the present invention is described with reference to fig. 3.

As shown in fig. 3, a dual-mode evaporation device includes: a first evaporation device and a second evaporation device, wherein the first evaporation device is disposed upwind of the second evaporation device, and wherein the first evaporation device comprises: a cavity with hollowed side surfaces; the atomizing devices are arranged in the cavity with the hollowed side surface and are used for atomizing the liquid into small liquid drops and quantitatively releasing the small liquid drops onto the evaporation fabric; the one or more evaporation fabrics are arranged at the hollow parts of the cavities with the hollow side surfaces and are used for enabling effective components in the liquid to enter a target space along with air flowing through the evaporation fabrics; wherein the plurality of nebulization devices ensure, in cooperation with one or more of the evaporation fabrics, a uniform distribution of the active principle in space and time, and wherein the second evaporation device comprises: the bottom hollow cavity body is positioned in the downwind direction of the hollow cavity bodies on the inner side surface and the outer side surface; the inner side surface and the outer side surface of the cavity are hollow; the atomizing devices are arranged at symmetrical positions on the side surface of the bottom hollow cavity body, are communicated with the inside of the bottom hollow cavity body and are used for atomizing the liquid into small liquid drops and quantitatively releasing the small liquid drops onto the evaporation fabric; the liquid enters the evaporating fabrics in the cavities with the inner side surface and the outer side surface hollowed out through the evaporating fabrics at the bottom of the bottom hollowed-out cavity, so that active ingredients in the liquid enter a target space along with air flowing through the evaporating fabrics; wherein the manner in which the plurality of atomization devices cooperate with the plurality of evaporation fabrics ensures that the active ingredient is distributed evenly in space-time.

This requires the disinfecting liquid to evaporate at a very low evaporation rate and to be distributed uniformly in space-time. The high-disinfection-component-concentration disinfection mode is used for quickly disinfecting and disinfecting an unmanned space, and the effective disinfecting and disinfecting component concentration in the space is required to be very high. This requires that the sterilizing fluid be vaporized at a high rate of vaporization to ensure rapid sterilization and disinfection of the target space.

The low-speed evaporation device, the high-speed evaporation device and the dual-mode evaporation device can be arranged in air ducts with proper sizes such as an air purifier, a fresh air system, an air conditioner and the like for use, and can also be matched with a fan for independent use.

When a low sterilant component concentration mode is desired, the low rate evaporator is operated, keeping the high rate evaporator off. The low-speed atomization device is started, and the hollow cavity on the side surface of the low-speed evaporation device is filled with atomized disinfection liquid drops. Part of the liquid drops are adsorbed on the side wall evaporation fabric, the air flow flows through the side wall of the low-speed evaporation device, the disinfectant on the side wall evaporation fabric is volatilized, the disinfection components enter the air flow, and the air flow enters the disinfection space after passing through the high-speed evaporation device.

When a high sterilant component concentration mode is desired, the high rate evaporator is operated, keeping the low rate evaporator off. The high-speed atomization device is started, and the atomized disinfection liquid drops enter the bottom hollow cavity body. The disinfectant entering the hollow cavity at the bottom enters the evaporation fabric in the cavity with the hollow inner side surface and the hollow outer side surface through the evaporation fabric at the bottom of the cavity. The air flow enters the cavity from the hollow-out part on the outer side surface of the cavity with the hollow-out inner side surface, passes through the evaporation fabric and then flows out from the hollow-out part on the inner side surface, and the disinfection component on the evaporation fabric enters the disinfection space along with the air flow.

The evaporation method achieves the aim of disinfection by quantitative constant-speed evaporation, gasification and release of disinfection components. The evaporation method changes the disinfection components into atomized liquid drops through the atomizer, transfers the atomized liquid drops onto the evaporation fabric, soaks the evaporation fabric, the atomized liquid drops are not directly released into flowing air, and the disinfection components enter a target space along with the air flowing through the evaporation fabric for disinfection. Quantitative constant-speed evaporation and gasification of the disinfection components and a low-disinfection-component concentration mode with people or a high-disinfection-component concentration mode without people are realized through mutual matching of different atomizer specifications, evaporation areas, thicknesses and the like of evaporation fabrics. The mode that the atomizer is matched with the evaporation fabric ensures that the effective components for sterilization and disinfection are uniformly distributed in space and time.
