Abstract

The utility model belongs to the field of energy utilization and discloses a closed type large-scale straw gasification system for producing charcoal. The closed type large-scale straw gasification system for producing the charcoal adopts the scheme that a plurality of purifying devices and filter devices are serially connected in a carbonization chamber in sequence, and combustible gas is stored in a gas storage tank for a user to use. As the combustible gas is produced by adopting the thermal cracking technology, no gasifying agent is needed, the heating value of the produced combustible gas is higher, and combustible matters which can not be gasified can be carbonized when the combustible gas is produced. Therefore, high-grade charcoal is produced, the utilization ratio of straw resources is greatly improved, and the economic benefit is improved.

Description

A kind of closed large-scale stalk produces the charcoal gasification system

Technical field

The utility model relates to the energy utilization technology field, especially is that a kind of closed large-scale stalk produces the charcoal gasification system.

Background technology

Gasifying stalk central gas supply technology is the new technology that the fuel in China's rural areas construction is released.It is to be raw material with the abundant abandoned biomass in rural area such as stalk, corn cob, rice husk, peanut skin etc., generates inflammable gas through pyrolysis and reduction reaction, delivers in the man of peasant household by pipe network, uses for cooking, heating.After this technology implementation, can reduce the direct great amount of carbon dioxide that is produced of burning of stalk and cause environmental pollution, reduce because the environmental pollution that the sulfurous gas of coal-fired generation causes.

The gasifying stalk central gas supply technology prematurity of promoting still at present, have following technical deficiency: at first, stalk only utilizes partial gasification in gasification, and the solids that contains combustiblecomponents of gasification is not handled as refuse, and stalk can not get utilizing fully; Secondly, large-scale gasifying stalk station administration, running cost height are difficult to extensive popularization; And there are shortcomings such as aerogenesis is of poor quality, calorific value is lower in the gasifying stalk central gas supply station of now building, and heating up water cooks needs overlong time.

The utility model content

For overcoming the deficiency of existing gasifying stalk technology, a kind of high heating value combustion gas that provides is provided the utility model, and the closed large-scale stalk that can produce charcoal again produces the charcoal gasification system.

For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions: a kind of closed large-scale stalk produces the charcoal gasification system, it is characterized in that: coking chamber connect successively tar settling chamber, spray column, solid cleaner, cooling purifier, high-power roots blower, eddy flow cleaner, water purifier, solid cleaner, the output terminal of solid cleaner connects large-scale gas-holder, and gas-holder is connected by gas line network with the user; Above-mentioned described tar settling chamber, spray column, solid cleaner, cooling purifier, eddy flow cleaner, water purifier, solid cleaner all are linked in the tar pond for recovering by pipeline.

Described coking chamber is made of the seal bootr of coking chamber pond and top, and the coking chamber bottom is provided with bottom lining and some gas collection small transfer lines, and some gas collection small transfer lines connect coking chamber rear portion equipment by the gas collection main pipe line.

Described closed large-scale stalk produces the charcoal gasification system and can insert a plurality of coking chambers.

The utility model is compared with conventional art, has following beneficial effect: adopt pyrolysis technology to produce inflammable gas, need not vaporized chemical, the inflammable gas calorific value of generation is higher, can reach 10-15mj/m3; Agriculture waste deposits yields inflammable gass such as the stalk while, the combustiblematerials that can not gasify carries out charing, produces the high-quality charcoal, has improved the utilization ratio of stalk resource greatly, has improved economic benefit.

Embodiment

Referring to accompanying drawing, coking chamber 1,2 connects

tar settling chamber

15,12 by air delivering pipeline, tar

settling chamber

15,12 connects integrated cleaner 14 inlets by air delivering pipeline, and integrated cleaner 14 delivery ports are successively by air delivering pipeline series connection spray column 3, solid cleaner 4, cooling purifier 5, high-power roots blower 11, eddy flow cleaner 6, water purifier 7,

solid cleaner

8,9; Spray column 3, solid cleaner 4, cooling purifier 5, eddy flow cleaner 6,

water purifier

7,8,9 solid cleaners,

tar settling chamber

12,14 integrated cleaners 15 all connect tar pond for recovering 13; The output terminal of solid cleaner 9 connects gas-holder 17, and gas-holder 17 is connected to the user by pipe network, has been equipped with spark arrester 10 near the user's gas output terminal.

Described gas-holder 17 is 800 cubic metres of underground type gas-holder.

Described coking chamber 1,2 is made of the seal bootr 18 of coking chamber pond 19 and top, and coking chamber 1,2 bottoms are provided with bottom lining 21 and some gas collection small transfer lines 20, and some gas collection small transfer lines 20 connect the equipment at coking chamber 1,2 rear portions by gas collection main pipe line 22.

Described closed large-scale stalk produces the charcoal gasification system and can insert a plurality of coking chambers 1,2.

Working mechanism of the present utility model is: agroforestry wastes such as stalk, corn cob, rice husk, peanut skin are joined in the coking chamber 1, by controlling the best carbonization temperature in the high-power roots blower 11 adjusting coking chambers 1, biomass are stored in 800m after the multiple processing that the inflammable gas that charing under the high temperature anaerobic environment, cracking produce precipitates, cools off, purifies by air delivering pipeline process successively ³Gas-holder in, use in order to the user, the tar that produces in the processing links of inflammable gas is recycled in the tar pond for recovering.After the charing solids buildup in the coking chamber 1 arrives to a certain degree, open coking chamber 2 and put into material and gasify, stop the operation of coking chamber 1, after the cooling charcoal is taken out.

The 1000m that adopts present technique to build ³Closed large-scale stalk produces the charcoal gasification station, but 1 ton of indefinite form charcoal of 3 tons of biomass material outputs every day, 3000 cubic metres of inflammable gass; Replace continuous production if build four coking chambers, produce 6000 cubic metres of inflammable gass every day, use the inflammable gas of energy-saving and environmental protection for peripheral peasant; And can 600 tons of charcoals of annual output, when solving village's domestic gas, create good economic benefit.
