Description

Anti-pollution infectious disease isolation ventilation equipment

Technical Field

The invention relates to an air purification treatment system, which belongs to the technical field of air treatment equipment; in particular to an anti-pollution isolation ventilation device special for a negative pressure isolation ward.

Background

The negative pressure isolation ward refers to a ward with air pressure inside the ward lower than air pressure outside the ward. This is also an important condition that has been particularly emphasized by the WHO when prescribing a rescue to a sars patient, which is difficult to achieve in many hospitals in the country.

The negative pressure ward is under the special apparatus, the air pressure in the ward is lower than the air pressure outside the ward, from the circulation of the air, only the fresh air outside can flow into the ward, the air polluted by the patient in the ward will not be leaked out, but is discharged to the fixed place in time through the special channel, so the place outside the ward will not be polluted, thereby reducing the chance that the medical staff is infected in large quantity, and the ward is most suitable for rescuing the respiratory infectious disease patient like SARS.

The negative pressure isolation ward generally comprises an isolation room (buffer room), a ward (patient room) and a toilet, which are isolated from each other by an isolation door, and adopts a negative pressure isolation technology, so that the discharge amount is larger than the air intake amount, the external negative pressure value of the ward is ensured to be more than-10 pa, and high negative pressure is formed.

The negative pressure isolation ward adopts one set of special ventilation equipment to realize negative pressure isolation to handle business turn over air, the following problem of prior art's ventilation equipment ubiquitous: 1. because ventilation equipment needs to handle exhaust waste gas, kill the infectious source virus in the waste gas, therefore, pipeline layout structure is complicated, bring inconvenience for transformation and maintenance, and it is many to leak the source, overhaul the investigation extremely troublesome, and ventilation equipment's air equipment is because need handle waste gas and new air that advances, therefore the structure is more complicated, bulky, and still need regularly change to this structure of exhaust-gas treatment, in order to guarantee effective exhaust-gas treatment, but because its structure is complicated and the accessory is more, it is very inconvenient to change, and many treatment equipment can only change on the spot, the inside remaining virus of equipment can reveal and lead to the virus diffusion, the security is relatively poor. 2. In the past, the pipeline system of the ventilation equipment, particularly the waste gas recovery pipeline system, is used for a long time, and the environment in the pipeline is dark and moist, viruses can be remained in the pipeline or bacteria can be bred, so that the cleanliness in the pipeline is extremely poor, the partial bacteria viruses can not only prolong the service life and the sterilization workload of subsequent waste gas treatment equipment, but also can cause the variation of the viruses infected in the pipeline to generate novel viruses, so that the subsequent waste gas treatment equipment can not be treated and discharged, the pollution is caused, and the viruses in the pipeline can enter a ward along with the air from an air inlet due to the suspension work of the waste gas recovery pipeline, and the secondary infection is caused to. 3. No matter whether new trend or waste gas, just directly let in indoor or discharge outdoor through handling the back, do not detect its gas quality, can't guarantee whether new trend and waste gas satisfy the requirement. 4. The isolation ward is required to guarantee indoor temperature and humidity besides meeting negative pressure conditions, previous ventilation equipment cannot be adjusted mostly, other temperature and humidity adjusting systems are required to be matched, and complexity of the structure is increased. 5. Waste gas is directly discharged, and fresh air is not pre-cooled or preheated, so that the power consumption of the temperature adjusting system is large, and the requirement of low energy consumption cannot be met.
