Fertilizer cake contg. full combustion coke for producing carbon dioxide

Abstract

A fully combustible coke-CO2 cake for generating gas fertilizer used in the plastic film shed in the winter is prepared from charcoal powder, desulfurized coke powder, gelatinized branch-chain starch, perchloric acid and kaolinite through proportional mixing, adding water, stirring, die pressing and drying.

Description

technical field [0001] The invention belongs to the field of carbon dioxide gas fertilizer, and in particular relates to an all-combustion coke carbon dioxide gas fertilizer cake and a special burner thereof, which are used for agricultural production in winter protection facilities such as plastic greenhouses to supplement the lack of carbon dioxide in the greenhouse. Background technique [0002] Carbon is an important raw material for the formation of photosynthetic products. Atmospheric and soil respiration is the uptake of CO by crops 2 The main source of CO, while atmospheric CO 2 The content has a certain range, and the CO released by soil respiration 2 It is affected by factors such as soil organic matter content, soil temperature, and microbial community. Winter and early spring heat preservation is an important task in the production of facility agriculture, and the heat preservation process affects the CO inside and outside the greenhouse. 2 AC, CO in greenhou...

Problems solved by technology

However, the photosynthetic CO of solanaceous fruits and legume vegetables in protected areas 2 The saturation point is at 1000-1500ppm. From November to March, the vegetable greenhouses in protected areas cannot communicate with the outside world due to the flow of thermal insulation air, and the green vegetables in the greenhouses grow rapidly. CO 2 The consumption is large, and its concentration is less than 300ppm, which is less than 60% of the concentration required for normal growth of vegetables. CO2 in the shed 2 Insufficiency seriously affects its photosynthesis, and the yield is difficult to further increase

[0004] Combining the above methods, each has its advantages and disadvantages. The traditional method takes up a lot of space, wastes the limited space in the greenhouse, is unsanitary, and has an initial odor; in the chemical method, it is difficult to control the amount of acid, and excessive or insufficient acid will cause waste of resources. Or environmental pollution, the cost is relatively high, and the direct combustion method does not burn completely; the engineering physics method not only concentrates equipment investment, but also uses CO 2 of vegetable plots and CO emissions 2 The distance between factories should not be too far, and the promotion limitations are large. The bioreactor method is very scientific in theory, but it is greatly affected by ground temperature and miscellaneous bacteria in practice, and the labor intensity is also relatively large, so it is difficult to promote

At the same time, due to the slow gas production, the instantaneous gas production at 8-10 o'clock every day still cannot meet the needs of normal growth of vegetables
