Problems solved by technology

[0003] The experimental waste gas purification device used in the existing laboratory air supply and exhaust system often cannot purify the waste gas efficiently, and the waste gas discharge is not up to standard, causing environmental pollution. In addition, the heat generated by the waste gas purification cannot be effectively used, resulting in waste of resources
Especially in winter, the indoor heat and exhaust gas purification heating heat are discharged into the room with the exhaust gas. If no heated fresh air is sent into the room, the indoor temperature will drop sharply and affect the indoor comfort. If the outdoor lower temperature air is directly heated to the required temperature, will consume a lot of heating energy

Abstract

The invention provides an air supplying and exhausting system capable of realizing waste gas purification and heat recovery. The air supplying and exhausting system comprises a waste gas purificationdevice, an air exhausting fan, a hot air heat exchanger, an air inlet fan, air inlet shutters, a water storage box and air exhausting shutters; a waste gas inlet of the waste gas purification device communicates with the air exhausting fan; the waste gas purification device is used for catalyzing oxidation waste gas; the hot air heat exchanger is provided with a hot gas inlet, a hot gas outlet, anair inlet and an air outlet; the hot gas inlet communicates with a waste gas outlet of the waste gas purification device through a gas delivery pipeline; the air inlet communicates with the air inletfan through a gas delivery pipeline; the air outlet communicates with the air inlet shutters through a gas delivery pipeline; a heat exchange pipe is arranged inside the water storage box; the two ends of the heat exchange pipe communicate with the hot gas outlet and the air exhausting shutters; waste gas exchanges heat with water in the water storage box; and the heated water can be supplied forindoor use. According to the air supplying and exhausting system, the indoor experimental waste gas can be exhausted after being subjected to catalytic oxidation treatment, the air and the water areheated by heat of the waste gas, the heat of the waste gas is recycled effectively, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of exhaust air purification and air supply in chemical laboratories, and in particular relates to an air supply and exhaust system with exhaust gas purification and heat recovery. Background technique [0002] During the chemical laboratory, organic and / or inorganic waste gas will be generated along with the experiment. The waste gas needs to be discharged to the outside through the exhaust air purification device, and the fresh outdoor air is sent into the room by the air supply device. [0003] The experimental waste gas purification device used in the existing laboratory air supply and exhaust system often cannot purify the waste gas efficiently, and the waste gas discharge is not up to standard, causing environmental pollution. In addition, the heat generated by the waste gas purification cannot be effectively used, resulting in waste of resources. Especially in winter, the indoor heat and exhaust gas pu...
