Embodiment 1

[0052] The present invention is described in detail as follows in conjunction with accompanying drawing:

[0053] Such as figure 2 As shown, the biomass pyrolysis device of the present invention for preparing smoked liquid and co-producing activated carbon comprises a feed hopper 1, a drying chamber 3, a pyrolysis furnace 5, an activation furnace 7, a discharge sealing tank 9, a 14, exhaust fan 15, three-stage condenser 16, gas cabinet 17, liquid collector 18, burner 19, low temperature flue gas pipeline 4, high temperature flue gas pipeline 6, pyrolysis gas pipeline 11, flue gas channel 13, activation Gas pipeline 20, normal temperature water cooling pipeline 21, normal temperature air cooling pipeline 22, high temperature water vapor pipeline 23, high temperature air pipeline 24, flue gas outlet pipeline 25, the feed hopper 1 passes through the material inlet of the drying chamber 3 and the pyrolysis furnace 5 The semi-coke outlet of the lower part of the pyrolysis furnace...

Embodiment 2

[0060] The device described in Example 1 was used to realize biomass pyrolysis polygeneration.

[0061] Step 1, the hawthorn core (moisture content is 15%) is sent into the pyrolysis reaction furnace 3 through the hopper 1, and the feed rate is 500kg / h;

[0062] Step 2. Control the reaction temperature of the drying furnace to be 200° C., the solid phase residence time to be 20 minutes, and the dry material to fall vertically into the pyrolysis furnace, and the feed rate is about 400 kg / h (moisture content is 5%);

[0063] Step 3. Control the pyrolysis reaction temperature to 500°C. The high-temperature pyrolysis gas phase product is passed into a three-stage condenser, and after condensation, a liquid product and a non-condensable combustible gas are obtained. The yields are 160kg / h and 80kg / h respectively, and the combustible gas The flow rate entering the burner is 80kg / h, and the combustible gas of 80kg / h is burned in the burner under the working condition of excess air co...

Abstract

The invention discloses a device and a method for preparation of liquid smoke and co-production of activated carbon by pyrolysis of Chinese hawthorn seeds. The device comprises a feed hopper, a drying chamber, a pyrolyzing furnace, an activating furnace, a gas condensation system, a gas cabinet, a combustor, an activated carbon cooling discharge system and a tail gas treatment device. According to the device, co-production of activated carbon can be realized while the liquid smoke is prepared, comprehensive utilization of the resources is realized, the phenomenon that attention is only paid to production of single product while the economic value of byproducts is neglected is avoided, pollution to the environment is avoided while energy is saved, heat required for the processes of drying, pyrolysis, carbonization, activation and the like of the Chinese hawthorn seeds is supplied by combustible gas of non-condensable gas, activating reaction gas and the like obtained by pyrolysis of the Chinese hawthorn seeds, self-sufficiency of the heat can be realized; according to the system, heat exchange is realized by low temperature air used for combustion of the combustor, vapor required for activation and high temperature activated carbon, each takes what it needs, at the same time, high temperature flue gas is exhausted after passing by the high temperature section and the low temperature section sequentially, gradient utilization of different layers of energy is realized, and the energy utilization efficiency is high.

Description

technical field [0001] The invention relates to the resource utilization of biomass, in particular to a pyrolysis polygeneration device and method for granular biomass (such as hawthorn core). Background technique [0002] In recent years, more and more attention has been paid to the edible and medical value of hawthorn seed smoked liquid. The smoked spice made from hawthorn core smoked liquid is a nationally recognized food additive, which is used to make food. It has a strong smoke aroma and a long-lasting fragrance. Hawthorn seed smoked liquid has obvious bactericidal, disinfecting and antibacterial effects. It is used to prepare ointments and creams to treat eczema, neurodermatitis, burns, etc., and has no irritation to the skin and mucous membranes, and has no toxic side effects. Hawthorn smoked liquid has a good market prospect both in food and medicine. [0003] The production of smoked liquid on the market mostly adopts static still retort equipment, and the static...
