The invention discloses a siphon circulation, contraflow heat regeneration and vapor compression distillation device, which utilizes siphon circulation to replace a circulation pump so as to drive feed liquid, and condensation latent heat can be cyclically recovered, so that the investment and the power consumption of the circulation pump are saved; contraflow heat regeneration and climbing-film evaporation of the feed liquid are commonly driven by the siphon circulation and outer pressure of a pipeline, so that evaporation latent heat is provided for generating secondary steam; large-temperature rise and small-temperature difference contraflow heat regeneration is adopted, so that not only is shell-pass evaporation pressure increased to a large extent, but also tube-pass condensation pressure is reduced to a large extent, the pressure difference, the emission and the power consumption of a water vapor compressor are reduced to a large extent, and the power consumption per ton water is reduced to 5 to 8 kW*h/t to a large extent; the falling head of the siphon circulation, contraflow heat regeneration and vapor compression distillation device is fully utilized, so that a condensed water discharging pump and a feed liquid discharging pump are omitted.

The invention relates to a tube-shell type heat exchanger which used the U-shaped cross-helical tube, involving an engine exhaust recycle heat exchanger. For improving the engine exhaust recycle system, accelerating the exhaust cooling and increasing the heat exchange efficiency. The heat exchanger includes the heat exchange tube, shell and the tube board, the heat exchange tube is the U shaped siphon, whose two ends fixed on the same tube board, the heat exchange tube is the stainless steel tube which has the entad raised cross-helical groove on the surface, the cross is the 'X'-shaped, the section shape of the stainless steel pipe is a special flat shape, and the height and width of the section shape in the flat shape heat exchange tube are unlikeness. Because of the application of the cross-helical heat exchange tube, the tube inside and outside produce the turbulent flow, not easy to dirty and increase the heat exchange efficiency. The heat exchanger has a compact structure, is particularly suitable for the exhaust gas recycle coolers of a vehicle engine, reduce the discharge of the nitrogen oxygen compound and enhance the exhaust discharge performance indicators, at the same time, the invention can also be used as the mid cooler of a turbocharger system to improve the engine performance.

The invention relates to an electric cooker. In order to improve the production efficiency by a simple structure even when the starch content of an object to be cooked is reduced during cooking, the present invention provides an electric cooker comprising: an inner container in which an accommodation space is formed; a separation plate which is attached to and detached from the interior of the inner container so as to divide the accommodation space into an upper side cooking area for accommodating an object to be cooked and a lower side water storage area for storing heated water, and has a siphon tube immersed in the heated water in the water storage area on the lower surface part so as to form an opening part in a way of connecting the siphon tube and the cooking area; a perforated platewhich is disposed at a distance from the opening part to the upper side and on which the object to be cooked is placed; and a separation plate gasket. When the inner container is heated, steam pressure of the water storage area is increased so as to arrange the heated water on the edge of the separation plate in a way of rising along the siphon tube to seal the space between the separation plateand the inner container.

The invention relates to a rubbish treatment system and method in order to solve the problem that low-cost rubbish treatment cannot be effectively conducted easily in the prior art. When the rubbish treatment method is used for treating rubbish, the rubbish manufactured by citizens is directly discharged into a municipal sewage pipe network after being smashed and is further scoured continuously by an intermittent siphon scouring and silting device, and accordingly pipeline silting can be prevented. The smashed rubbish is mixed into original municipal sewage and then is conveyed to a service reservoir through the municipal sewage pipe network, the rubbish is matched with farmer market rubbish collected to be made into sewage with the COD content and power of hydrogen being suitable for meeting the growing requirements of methane bacteria, part of organic matter in the sewage can be decomposed into biogas quickly after the sewage passes through a fast biogas digester, and biogas slurry which is not decomposed in the fast biogas digester is then conveyed into a low-speed biogas digester to be fully decomposed to produce a large amount of biogas in the low-speed biogas digester together with collected food waste. By means of the rubbish treatment system and method, the municipal rubbish and sewage can be recovered and treated to the greatest degree, and meanwhile the blocking problem of city sewer lines can be solved.
