Abstract
The utility model relates to a residue recovery device for pumping with the ethanol method, belonging to the technical field of the paper pulping device, which is mainly characterized in that a liquid tank and a flash tank are connected with tubes, the upper and lower ends of the flash tank are separately connected with a heat exchanger and a distillation tower with tubes, and the other ends of the heat exchanger and the distillation tower are respectively connected with a storage tank with tubes; a tube, positioned at the bottom of the distillation tower, connects with the multiple-effect evaporator, the upper end of the multiple-effect evaporator is provided with a tube to connect with the heat exchanger and the lower end is provided with a tube to connect with a spray drier. The utility model has simple structure, low cost, convenient installation and service, can fully recover ethanol and lignin in pulping residue, improves the utilization factor of chemical feedstock, effectively reduces environmental pollution in the paper-making industry, really realizes non-pollution discharge in the pulping steaming procedure and has high economic and social benefits.
Description
One, technical field
The utility model relates to a kind of recycling and processing device of paper-making pulping gained raffinate, relates in particular to a kind of ethanol pulping raffinate retracting device, belongs to technical field of papermaking and pulping equipment.
Two, background technology
In traditional chemical pulp or the semi-chemical pulp manufacture process, all to use a certain amount of inorganic chemical under High Temperature High Pressure, plant fiber material to be carried out chemical action, so that fiber separation is come out.Yet the waste liquid waste gas that it produced causes severe contamination to environment.For addressing this problem, self-catalysis ethanol pulping technology and device have appearred, contain a large amount of ethanol and other organic substance in the ethanol pulping raffinate, if can not effectively reclaim to these materials, the one, can not reach and eliminate the ethanol pulping pollution on the environment, the 2nd, waste of raw materials is big, and the economic feasibility of this method and apparatus also is a problem.The ethanol pulping technology is in the experiment trial production stage always, and the one of the main reasons that can not apply is exactly that effective recovery problem of raffinate is not well solved.
Three, summary of the invention
The utility model is to reclaim the problem that difficulty can not be applied in order to solve the ethanol pulping technology because of raffinate, and environmental pollution is serious, the big and a kind of new technical scheme that proposes of wastage of material.
The utility model is achieved in that a kind of ethanol pulping raffinate retracting device, the recovery of its ethanol and lignin is by realizing with lower device: it is to be formed by connecting by pipeline by fluid reservoir, flash tank, heat exchanger, destilling tower, storage tank, multi-effect evaporator and spray dryer, fluid reservoir is connected by pipeline with flash tank, the two ends up and down of flash tank respectively with heat exchanger and destilling tower mutually pipeline be connected, the other end of heat exchanger and destilling tower is managed mutually with storage tank respectively and is connected; Be provided with a pipeline in the bottom of destilling tower and be connected with multi-effect evaporator, the upper end of multi-effect evaporator is provided with pipeline and is connected with heat exchanger, the lower end is provided with pipeline and is connected with spray dryer, the upper end of spray dryer is provided with pipeline and is connected with heat exchanger, and the other end of heat exchanger is connected by pipeline with storage tank.Be provided with pipeline at the two ends of heat exchanger and be used to carry out heat exchange.
The utility model has the advantages that: the equipment combination is simple, cost is low, easy to install, can fully reclaim ethanol and lignin in the slurrying raffinate, improved the utilization rate of fibrous raw material and chemical raw material, reduced the pollution of paper industry effectively, really realized the non-pollution discharge of pulping and digesting operation, had very high economic benefit and social benefit environment.When organic matter reclaims, realized energy recovery, improved the service efficiency of the energy.
Four, description of drawings
Accompanying drawing is the utility model overall structure schematic diagram.
Five, the specific embodiment
Cylindrical seal fluid reservoir (1) is used to store the High Temperature High Pressure slurrying raffinate that ejects from the paper-making pulping cooking pot, fluid reservoir (1) is connected by pipeline with flash tank (2), lignin liquor is pressed into the flash tank (2) from fluid reservoir (1), the two ends up and down of flash tank (2) are connected by pipeline with destilling tower (4) with heat exchanger (3) respectively, and the other end of heat exchanger (3) and destilling tower (4) is connected with storage tank (5) by pipeline respectively; Be provided with a pipeline in the bottom of destilling tower (4) and be connected with multi-effect evaporator (6), the upper end of multi-effect evaporator (6) is provided with pipeline and is connected with heat exchanger (7), the lower end is provided with pipeline and is connected with spray dryer (10), the upper end of spray dryer (10) is provided with pipeline and is connected with heat exchanger (9), and the other end of heat exchanger (7,9) is connected by pipeline with storage tank (8).Be provided with pipeline at the two ends of heat exchanger (3,7,9) and be used to carry out heat exchange, so that fully effectively utilize heat energy in the slurrying raffinate removal process.
Claims (2)
