The invention relates to the technical field of rainwater resource collection and utilization, in particular to an energy-saving rainwater collector. The energy-saving rainwater collector comprises a rainwater collecting groove, a water guide hose and a water accumulating tank. The energy-saving rainwater collector is characterized in that the water collecting groove is a disc-like rainwater collecting plate; a water guide hard pipe consisting of a branch pipe and a horizontal pipe is arranged between the rainwater collecting plate and the water guide hose; the device is adsorbed to window glass by a suction plate arranged at the tail end of the horizontal pipe; a water outlet hole is formed in the lower end of the horizontal pipe at the position, corresponding to a dripping groove, in the water guide hard pipe, and is connected with a sucker placement pipe; a groove is formed in the upper end of the horizontal pipe corresponding to a water outlet; a sucker placement opening is formed in the groove; the lower end of a sucker is matched with the sucker placement pipe; and the upper end of the sucker pipe is led out through the horizontal pipe and the sucker placement opening in sequence and is propped against the inner wall of the dripping groove. The dripping groove is fully filled with rainwater under the condition of a heavy rain or a storm; and the rainwater can flow along the sucker, so as to enter the water accumulating tank along the water guide hose, so that the energy-saving rainwater collector has the advantages of simple structure, energy conversation, portability, low cost, good water collecting effect and the like.

The invention relates to a method for high temperature and high pressure production of sodium methoxide and a device thereof. The production method comprises the steps of alkali dissolution, synthesis and drying. The main device comprises an alkali dissolution liquid tank, a clear liquid tank, a reaction tower, a rectifying tower and a vacuum drier. The reaction is performed under the conditions of high temperature and high pressure to produce sodium methoxide, alkali in raw material methine liquid is in a supersaturated state, the reaction is full, the yield is improved to 99.5% from about 98% compared with a conventional process, and the content of free alkali in sodium methoxide is smaller than 0.4%. For the production of each ton of sodium methoxide product, the power consumption is reduced by 18 KWh, and steam is reduced by 2.5 tons. According to the method, continuous industrial production controlled by a distributed control system is implemented, workers' labor intensity is reduced greatly, materials are all conveyed in a sealed space, environmental pollution caused by harmful gas is avoided, the method and the device save energy and are good in consumption reduction, and the product competiveness is high.

The invention discloses a high-density fish and vegetable co-existing system which comprises fish tanks, a planting system and a water storage tank, wherein the planting system comprises hydroponic vegetable breeding grooves and river stone breeding beds; the fish tanks are connected with flow diversion tanks and a solid sewage separation tank; the solid sewage separation tank is connected with a bacterial sewage decomposition tank; the bacterial sewage decomposition tank is connected with the water storage tank; the water storage tank is connected with the flow diversion tanks through a water pump; the flow diversion tanks are connected with the planting system; the other end of the planting system is connected with the water storage tank through a pipeline. A fish breeding system is adopted for generating nutritional water, and the nutritional water is diverted into the planting system through the flow diversion tanks and provides normal nutrition for plant growth; large-scale high-density production can be realized and the efficiency is high; water subjected to multiple purification is relatively good in quality; breeding and planting system structures are independent; the co-existing system is simple in structure and convenient to manage and maintain; the breeding system is low in operation cost, low in energy consumption and environment-friendly; the co-existing system has the characteristics of simple structure, stability and convenience for mounting, maintenance and operation; diversity of culture of leaf vegetables and melon and fruit vegetables can be realized.
