Waste heat utilization cyclone separator

Abstract

The invention provides an afterheat utilization cyclone separator, which comprises a casing, a dust-containing gas inlet, a gas inlet distributor, a dust discharging opening and a clean gas outlet, wherein the dust-containing gas inlet is formed in the lateral part of the casing; the dust discharging opening is formed in the lower end of the casing; the clean gas outlet is formed in the top of the casing; a group of spiral pipelines are arranged in the casing; the upper end of the group of the spiral pipelines is communicated with the dust-containing gas inlet in a sealed way; the lower end of the group of spiral pipelines is communicated with the dust discharging opening in a sealed way; the dust discharging opening is communicated with the clean gas outlet in a sealed way through a gas ascending pipe; the dust discharging opening is isolated from a shell space of the casing; the upper side and the lower side of the casing are respectively provided with a heat exchange medium inlet and a heat exchange medium outlet of the shell space. The dust-containing high-temperature gas enters the dust discharging opening through spiral pipes; gas in the spiral pipes flows at high speed, and performs heat exchange with heat exchange media of the shell space through the pipe wall; the heat exchange efficiency is improved; the heat exchange area is increased; the integral size is smaller; the integration degree is high.

Description

technical field [0001] The invention relates to a cyclone separator, in particular to a waste heat utilization cyclone separator. Background technique [0002] At present, China's industrial development has entered a new stage, and environmental problems such as air pollution and water pollution have become increasingly prominent, which have seriously affected people's normal life and health, and have attracted more and more attention. A large amount of organic gases harmful to the environment are produced in the industrial production process. In this case, it is necessary to increase the research and development of organic waste gas treatment technology, and reduce the harm to the atmospheric environment by improving waste gas treatment technology. In the chemical industry, solid-gas separation devices are often used to remove impurities such as dust particles in the gas. Cyclone separators are the most widely used, but a single cyclone separator cannot solve the problem o...

Problems solved by technology

Both methods have certain disadvantages: the first method is that the smoke and dust in the flue gas will block the flue gas channel of the heat exchanger, and after a long time, the high-temperature smoke and dust adhering to the heat exchange surface will increase the thermal resistance of the heat exchange surface , so the heat transfer efficiency is reduced, which affects the heat transfer effect of the equipment; and, for the waste heat recovery of high-temperature gas, it is easy to cause thermal stress corrosion

If the second method is used, the temperature of the flue gas will be reduced during the dust removal process in the dust removal equipment, resulting in a certain amount of waste heat loss

[0004] In addition, since the viscosity of high-temperature flue gas is higher than that of low-temperature flue gas, the resistance loss of flue gas in the dust collector increases, which requires more power consumption, resulting in waste of energy
