Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to a high-efficiency and energy-saving flue gas drying device. Background Art

[0002] To achieve gas-liquid separation in flue gas, the water in the flue gas must first be liquefied, and the flue gas temperature must be reduced to the liquefaction temperature. The pressure of the drying box is about 0.2Mpa-0.3Mpa, and the temperature is maintained at 0-5℃. Therefore, to liquefy the water in the flue gas, a lower temperature cold flow liquid must be used for cooling; the main heat exchanger and condenser evaporator in the drying device play a key role in the production of liquid. The main heat exchanger uses the low-temperature and low-pressure gas after expansion as the counterflow gas of the heat exchanger to cool the high-pressure positive flow flue gas, so that its temperature before expansion is gradually reduced; at the same time, the temperature after expansion is gradually reduced until it finally reaches the temperature required for liquefaction.

[0003] The current gas drying methods are divided into: adsorption drying, membrane separation drying, chemical drying, compression drying, etc.; the drying equipment is large in size, high in energy consumption, and high in cost; there is a high probability of leakage or blockage during the gas drying process, which not only affects the production quality but also causes serious air pollution to the production environment. The detection process is cumbersome and difficult to detect. It is difficult to fully detect the pipelines inside the equipment, which is prone to safety accidents caused by missed detection and false detection. For this reason, we propose an energy-saving flue gas drying device. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide an energy-saving flue gas drying device with the advantages of large drying capacity and energy saving, which solves the problems of high energy consumption and unstable drying performance of previous flue gas drying equipment, which easily lead to the pollution of the environment by smoke and water vapor carried in the flue gas, including: air quality, climate change, soil and water pollution, corrosion of buildings and materials, destruction of ecosystems, etc.; for this reason, we provide an energy-saving flue gas drying device with a new structural configuration, which is mainly composed of a wind-driven engine, a process-oriented module, an intelligent foam-breaking matrix, a thermal engine device and a cloud and mist disperser. The various devices are interconnected by corresponding pipelines to improve the working efficiency of the drying system.

The first inlet of the intelligent temperature-controlled drying cabinet is connected to a wind-driven engine fixed to the input end of the intelligent temperature-controlled drying cabinet and connected to the chimney pipe. The intelligent temperature-controlled drying cabinet is provided with a secondary process guide module in the intelligent temperature-controlled drying cabinet at the wind-driven engine outlet.

In view of the above requirements, the present application provides an energy-saving flue gas drying device. The specific steps of the intelligent temperature-controlled flue gas drying cabinet process are as follows: Step 1: To meet the above requirements, the flue gas enters the temperature-controlled drying cabinet from the air inlet through the high-pressure pipeline under the impetus of the wind-driven engine. Temperature and humidity sensors are provided before and after the wind-driven engine.

When the valve is fully opened, the flue gas passes through the thermal engine device for 0.1 minutes. The thermal engine is started. When the temperature of the thermal engine is lower than -3°C, the heater stops running. When the temperature of the thermal engine is lower than 0°C, the heater starts heating. Step 4: To meet the above requirements, the flue gas is connected to a mist disperser after passing through the heat engine device, and a temperature and humidity sensor is provided in front of the mist disperser; Step 5: To meet the above requirements, the flue gas is provided with a rich liquid guide groove in the secondary process guide module, and converges at the bottom of the temperature-controlled drying cabinet; Step 6: To meet the above requirements, the flue gas is provided with temperature and humidity detection sensors and a rich liquid confluence trough in the intelligent foam breaking matrix system; Step 7: To meet the above requirements, the flue gas is provided with a rich liquid introduction pipeline and an energy artery pipe on the heat engine; intelligent detection pressure sensors are provided at both ends of the pipeline; Step 9: To meet the above requirements, the smoke is provided with an ice crystal collection device on the cloud and mist dispersal device, and is also equipped with a DC temperature controller; Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an energy-saving flue gas drying device. Through the pressure detection mechanism, when the air pressure in the gas pipeline is too high or too low, the wind-driven engine automatically performs the conditions after receiving the instruction sent by the pressure detection mechanism; The present invention discloses an energy-saving flue gas drying device, which obtains accurate data of flue gas dryness by analyzing and processing the collected gas pipeline pressure data and combining the data fusion comparison of the database, and utilizes the combined advantages of multiple information sources to improve drying efficiency and data accuracy.
