At first, this product generally is to be used as the byproduct of firing bamboo charcoal, therefore exist the firing time long, technological process is loaded down with trivial details, the equipment requirements complexity because the fuel of firing in the bamboo charcoal process is timber, is not only destroyed ecotope again, and generation wood vinegar, because wood vinegar is difficult to separate with bamboo vinegar liquid, directly influences the component and the character of bamboo vinegar liquid, thereby influences the effective ingredient of bamboo vinegar liquid.Patent " preparation method of bamboo charcoal liquid " (02142381.4) has proposed use bamboo wood tankage and has done fuel, solved bamboo wood vinegar blended problem, but also exist collection effciency not ideal enough in process of production, ash content is many, problems such as component instability, in addition, routine techniques is according to measuring the opportunity that temperature decides the collection flue gas to carry out condensation in the stove, because temperature fall is bigger in the stove, the reasons such as difference of different body of heater specifications aspect, decide the operation of throat to be inaccurate with temperature in the stove, also untimely, the original liquid component that causes thus gathering differs greatly, and concentration and stability are all not satisfactory; The destructive distillation flue gas condensing is being become in the liquid process, routine techniques is to use the metal condensation device in the majority, because of metallics very easily with bamboo vinegar stoste in multiple organism generation chemical reaction, cause ash content and throw out to increase and the effective constituent minimizing, even metal condensation device through corrosion-resistance treatment, also can only play reduction effect to a certain degree, and can not avoid the problems referred to above, moreover dustiness is big in the flue gas, complicated component, the metal condensation device is easy to stop up, if improve bore and other corresponding component specifications of change of its prolong in order to improve stopping state, can cause this condensation vessel volume huge, make troubles, and manufacturing cost will be far above conventional chemical industry condensing equipment to operation and maintenance.

Summary of the invention

The present invention mainly is that solution existing in prior technology collection effciency is undesirable, ash content is many, the technical problem of component instability, easy obstruction etc., it has not only reduced the ash oontent in the bamboo vinegar stoste, when enhancing productivity with the product yield, also reduced device fabrication cost and maintenance cost, because of collecting omnidistance no metal material, its product stability, effective ingredient are higher.

Above-mentioned technical problem of the present invention mainly solves by following technical proposals: at chimney outlet temperature measuring equipment is set, when reaching 60 ℃ of left and right sides, temperature begins to gather the destructive distillation flue gas, this moment flue gas be thick black or brownish black, smell is pungent, flue gas is imported collection tube, and flue gas enters container by collection tube; Container top is the water of condensation bogey, and its contained condensation depth of water is not less than 10cm, has some apertures on the water of condensation bogey, and bamboo matter prolong is installed in the hole, and with cemented; Bamboo matter prolong one end feeds container one end and air communication; Because the effect of the temperature difference and pressure reduction, flue gas rises along prolong, walks to the water of condensation section, has partial fume to condense into liquid, falls into container bottom along bamboo matter condensation tube wall; The flue gas that carries waste heat continues to rise, and by bamboo matter condensation tube wall and extraneous air heat-shift, mostly forms lime set until effective constituent, falls into container bottom along bamboo matter condensation tube wall; Throat has the sorrel fluent meterial to occur in the time of about 260 ℃, fragrant odour, and stop to gather the destructive distillation flue gas this moment, and the lime set of compiling enters hold-up vessel by the liquid discharge pipe that is located at container bottom, finishes the collection of bamboo vinegar stoste.

As preferably, described temperature measuring equipment is mounted in the chimney, be not less than 10cm with the distance of throat, be subjected to cause influences such as outside atmosphere and weather because of the throat temperature, 10cm is bigger with interior temperature fluctuation, being difficult to as the control foundation of gathering flue gas, is accuracy and the stability that guarantees temperature parameter, and temperature measuring equipment must be not less than 10cm with distance with throat.

As preferably, the quantity of bamboo matter prolong is preferably in 2～5/m2; Perhaps bamboo matter condensation section length preferably is not less than 1 meter; Or bamboo matter prolong bore is preferably between 1cm～20cm, and wherein the enforcement of arbitrary measure all can improve heat exchanger effectiveness, keeps the uniform and stable of bamboo vinegar stoste quality content.

Therefore, the present invention has that product composition is stable, and ash content is low, enhance productivity and the product yield in, also reduced device fabrication cost and maintenance cost, because of collecting omnidistance no metal material, its product stability, effective ingredient are higher.
