Novel draught fan with gas information feedback function used for power plant

Abstract

The invention discloses a novel draught fan with a gas information feedback function used for a power plant. The novel draught fan comprises a novel draught fan body, an air inlet, a return air inlet, a low efficient filter, a high efficiency filter, a gas monitoring chamber, a monitor, an information feedback device, a signal transmission hole, a pressurizing chamber, a pressurizer, an electromotor box, an electromotor rotating wheel, a driving belt, a draught fan rotating wheel, a draught fan, an air outlet, an evaporator and a draught fan fixing device, wherein the air inlet is formed in the left side of the novel draught fan body; the gas monitoring chamber is arranged on the right side of the high efficiency filter; the monitor is mounted in the gas monitoring chamber; and the air outlet is formed in the right side of the draught fan. According to the novel draught fan with the gas information feedback function used for the power plant, not only is the structure firm and steady, but also the draught fan operates more smoothly, the information of a gas in the gas monitoring chamber is fed back to an external indicator through the signal transmission hole, so that monitoring and feedback of a gas in the draught fan are more direct, exhausted gas is purer and cleaner, and the impurity removing efficiency of the high efficiency filter is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a novel gas information feedback fan for power plants. Background technique [0002] With the improvement of people's living standards, the requirements for quality of life and health are also increasing. In order to ensure that the indoor air is fresh and pure, a blower with purification function is usually installed. However, in the existing structure, the air inlet and outlet process of the blower In the process, the outgoing airflow and the supplementary airflow will interact, which will cause the newly supplementary airflow to be polluted by the airflow to be sent out, thus making it impossible to maintain the purity of the indoor air. [0003] At present, the fresh air ventilators provided on the market can be divided into two categories, one is only for the introduction of fresh air and the removal of dirty air after the primary filter, without the function of energy recovery...

[0002] With the improvement of people's living standards, the requirements for quality of life and health are also increasing. In order to ensure that the indoor air is fresh and pure, a blower with purification function is usually installed. However, in the existing structure, the air inlet and outlet process of the blower In the process, the outgoing airflow and the supplementary airflow will interact, which will cause the newly supplementary airflow to be polluted by the airflow to be sent out, thus making it impossible to maintain the purity of the indoor air

[0003] At present, the fresh air ventilators provided on the market can be divided into two categories, one is only for the introduction of fresh air and the removal of dirty air after the primary filter, without the function of energy recovery, and the other is based on the former type The energy recovery function of fresh air and exhaust air is added. The above two types of fresh air ventilation units can only initially filter large-diameter suspended particles in the air. Second, they do not effectively remove PM2.5, formaldehyde, benzene, and ammonia in the fresh air. , TVOC, nitrogen and sulfur compounds and other pollutants, the fresh air is not completely purified
