Odor heat exchange condensation system and method

Abstract

The invention discloses an odor heat exchange condensation system and method. The system comprises a heat exchange condenser, a temperature sensor, a biological deodorization device, a detection control device, an odor collection pipeline and an odor exhaust pipeline. The heat exchange condenser comprises an upper end cover, a tank body and a lower end cover. The odor collection pipeline is fixedly connected with the upper end cover. The lower end cover is fixedly connected with the odor exhaust pipeline. The odor exhaust pipeline is connected with the biological deodorization device through an induced draft fan. A bypass branch and a bypass branch solenoid valve are further connected between the odor collection pipeline and the induced draft fan. A fresh air inlet flange and a hot air exhaust flange are arranged on the side wall of the tank body, and hot air is connected with a heat energy load. An air heat exchanger is mounted in the tank body. The temperature sensor mounted at an odor exhaust opening of the heat exchange condenser is connected with the detection control device. The detection control device controls an odor inlet solenoid valve or the bypass branch solenoid valve. According to the odor heat exchange condensation system and method, microorganism dormancy and death are avoided, the deodorization effect is guaranteed, and heat energy can be provided.

Description

technical field [0001] The invention belongs to the technical field of pollution control, and in particular relates to a heat exchange and condensation system and method for organic waste fermentation odor. Background technique [0002] In the process of industrial and agricultural production, sewage treatment, garbage disposal and composting, a large amount of odor and organic waste gas will be produced, which not only pollutes the surrounding environment, but also causes serious harm to human health and the ecological environment. Governance is getting more and more attention. [0003] During the fermentation process of organic waste, microorganisms oxidize part of the organic matter into simple inorganic matter through metabolic activities to provide the energy required for biological life activities, and the other part of the organic matter is converted into the nutrients required by the organism to form new The cell body makes the microorganisms proliferate continuousl...

Problems solved by technology

[0004] Mineral raw materials such as coal, diesel oil, etc. will inevitably produce soot and other particulate matter, carbon monoxide (CO), sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) and other toxic and harmful gases. At the same time, the combustion tail gas will also take away a large amount of heat, and this part of the heat will not be used, resulting in waste of heat energy and aggravating environmental pollution.

[0005] There are many technologies for controlling odor and organic waste gas, such as absorption and adsorption, incineration, chemical conversion, condensation and biological methods, but among these methods, the most economical and effective is the biological deodorization method, which is A deodorizing and harmless process method, that is, using microbial flora with deodorizing function to transform hydrogen sulfide, reduced sulfide and other odorous substances in waste gas, with high removal rate, low operating cost, and simple operation and management , no secondary pollution, etc., but the deodorization effect of the biological deodorization method depends on the activity of deodorizing microorganisms. Too high or too low air intake temperature will affect the growth and reproduction of microorganisms, thereby reducing the deodorizing effect. When the odorous intake air temperature is higher than 40°C or lower than 15°C, the growth and reproduction of deodorizing microorganisms will be inhibited; when the deodorizing intake air temperature is higher than 60°C, a large number of deodorizing microorganisms will die, and the deodorizing effect will be lost
