Chain track enterclose type anoxia ebb fried drying, burning and burningcandle decomposition apparatus

Abstract

The invention discloses to a chain way dividing wall type anoxia weak explosion drying, incineration and ablative pyrogenation device which comprises a heat generation system, a constant temperature space and a mechanical and electrical integration complete equipment of control system, wherein, the constant temperature space is a closed shell formed by vertical walls, an upper end cap and a low end cap, the average temperature in the constant temperature space is between 80 DEG C and 1000 DEG C, the shell a cylinder around which a heat-resistant thermal insulating layer is arranged; each chain way heat exchanger comprises a cable chain, a cable chain driving device and a dividing wall chamber; the raw materials pass through a up-chain way and a down-chain way taken as a moisture evaporation section, a pyrogenation gas evaporation section and a high temperature section to continuously finish the evaporation and the pyrogenation of the moisture as well as the pulverization and the drying or the incineration of the charcoal. The invention meets the requirements of drying and manufacturing combustible gas and charry or liquid fuel on the basis of the principles of the dividing wall, the radiation, the constant weak and general explosion of anoxic/anaerobic explosion water and ablation heat transfer principle. The invention has higher ability of heat and mass transfer, the volume of the system is greatly decreased, all the energy can be supplied by the raw materials, the treatment cost is greatly decreased, and the invention is particularly suitable for sludge minimization treatment in sewage treatment plants.

Description

technical field [0001] The invention relates to a highly water-containing, extremely viscous and fine-grained material chain-channel partition wall type anoxic weak frying drying, incineration and candle pyrolysis device, which belongs to the fields of energy chemical industry, renewable resources and environmental protection; the device is especially suitable for sewage Mud treatment, river dredging mud treatment, drilling mud treatment, coal washing slime treatment, biomass liquefaction and livestock and poultry breeding pollutants treatment and other projects. Background technique [0002] In the process of urbanization, with the improvement and deepening of sewage treatment rate and treatment degree, the output of sludge as biomass has greatly increased. How to make these sludge harmless and resourceful is a problem that all countries in the world pay attention to. In my country, a large country with less abundant funds, lower agricultural production efficiency, more pre...

AI Technical Summary

Problems solved by technology

The organic matter in the sludge is about 50%, and the calorific value of the dry mixed sludge is 24-29MJ/kg. Theoretically, the calorific value held by itself can only be burned when the water content is lower than 70%. Moisture is a better fuel and can generate sufficient heat; however, existing sludge drying or incineration equipment such as rotary kiln, rotary furnace, spouted bed, etc., due to the high water content, high viscosity and solidification of sludge Severe fouling characteristics, low efficiency of equipment, because of large volume, heavy equipment is not easy to move; complex process, high investment, and need to remove a lot of water to be used as raw materials for treatment, and the sludge dust that is inevitably generated during the drying process easy to explode

In the published technical data of the chain-type drying and pyrolysis oil production device and system, only the application numbers 200610159744
