Description
Technical field
The utility model relates to a kind of gas cleaning unit, is specifically related to a kind of aldehyde vapour wash mill.
Background technology
Furfural (furfural) has another name called furtural, is a kind of light yellow or amber sparkling and crystal-clear transparency liquid, does not have mechanical impurity, physical property: colourless oil liquid has the special odor of similar benzaldehyde.Be exposed to that color becomes rufous very soon in light and the air, inflammable, easily and steam together volatilize.Its steam and air form explosive mixture, are slightly soluble in water, are soluble in ethanol, ether.Furfural is a kind of important organic chemical industry's product, and it has purposes widely in fields such as synthetic resin, petroleum refining, fuel, medicine and light industries.Furfural mainly is to utilize the pentosan in the plant fiber material to produce, and all plant fiber materials that is rich in pentosan all are applicable to furfural production, as corncob, cotton seed hulls, oil tea shell, sunflower pericarp, bagasse and rice husk etc.
Plant fiber material is under the effect of acidic catalyst during the preparation furfural, and through the pressurization that heats up, pentosan wherein is hydrolyzed and generates pentose earlier, and dehydration makes furfural then.At present, traditional furfural production technology is as follows substantially: acid, hydrolysis are pulverized, mixed to plant fiber material, and the aldehyde vapour that hydrolysis produces is made the furfural finished product through subsequent handling.Owing to contain the solid impurity of furfural dregs class in the furfural gas that hydrolysis produces, enter subsequent handling again after these solid impurities need being removed.The solid impurity of removing aldehyde vapour at present is to connect the cyclone dust removal scummer to remove behind hydrolysis kettle, also need to increase cleaner, and the impurity of this method to remove rate low, at 80% time, increase the distillation load and the cleaning frequency (1 time/20 days) of subsequent processing primary distillation tower like this, increased the production cost of furfural greatly.
The utility model content
The purpose of this utility model provides a kind of simple in structure, aldehyde vapour wash mill that use cost is low, can remove the solid impurity of aldehyde vapour in carrying effectively.
For achieving the above object, the utility model is by the following technical solutions:
A kind of aldehyde vapour wash mill, comprise tank body, the sidewall of tank body is provided with air inlet, the inner tank wall at air inlet place is provided with baffle plate, and the upper end of baffle plate is higher than air inlet, and the lower end of baffle plate is lower than air inlet, the baffle plate place that is lower than air inlet is provided with a poroid plate, tank body top is provided with the gas outlet, and the tank body bottom is provided with water inlet pipe, and tank base is provided with blow-off pipe.
Described gas outlet is positioned at the top of tank body, is provided with demister in the tank body of baffle plate top.
Described baffle plate is folding shape.
Described poroid plate level setting.
Described tank body is provided with liquid level gauge, is convenient to observe water level in the tank body.
Described tank body is provided with visor, observes water level in the tank body when losing efficacy in order to liquid level gauge.
The utility model is provided with the flow direction that baffle plate makes aldehyde vapour and changes into downwards at the air inlet place, thereby goes into the aldehyde vapour pressure under water, makes aldehyde vapour clean wherein entrained solid impurity through washing; Poroid plate is set prevents that aldehyde vapour from directly spraying the water surface, lose the effect of washing, aldehyde vapour is evenly distributed in water; Demister is set is used for removing the drop that aldehyde vapour carries; Liquid level gauge is set, is convenient to observe the water level in the tank body, can control the height of water level at any time, easy and simple to handle, use very conveniently, when losing efficacy in order to liquid level gauge, observes visor the interior water level of tank body.
When using, the utility model in tank body, adds entry by water inlet pipe, the height that guarantees the water surface is between air inlet and poroid plate, both prevented that liquid from discharging by air inlet, also brought into play the due effect of poroid plate, aldehyde vapour flows downward under the effect of baffle plate and enters under water like this, makes aldehyde vapour clean wherein entrained solid impurity through washing, and aldehyde vapour leaving water is removed the drop that wherein carries towards last through demister then, finally discharge, become clean aldehyde vapour from the gas outlet.
The utility model making reasonable in design, simple in structure, easy, easy to operate, cost is lower, the rate of removing height to solid impurity in the aldehyde vapour, reach more than 99%, protected the still-process of the primary distillation tower of postorder effectively, reduced the distillation load of primary distillation tower, reduce cleaning frequency (1 time/180 days), reduced production cost, improved the business economic benefit; And the utility model need not periodic inspection and need not regularly replace part of appliance, and it is applied widely, has good economic and social benefit after the popularization.
