Embodiment 1

[0030] First add 2 parts by weight of dilute hydrochloric acid (concentration: 10%) to the sludge, and stir evenly; then add 8-12 parts by weight of coalification agent, 3 parts by weight of calcium chloride, and 0.2 parts by weight of amylase, and stir evenly ; After aging and aging for 26 hours, granulate and serve.

[0031] The production process of the coalification agent is: put 65 parts by weight of waste rubber into the mixer, heat it to 140°C, add 3 parts by weight of coal tar, keep the temperature at 165°C, add 2.5 parts by weight of sodium alkylbenzene sulfonate; 20min Then add 5 parts by weight of polyethylene and stir. After 25 minutes, heat up to 182°C and then add 0.3 parts by weight of polypropylene. After stirring for 20 minutes, lower the temperature to less than 24°C, then add 8 parts by weight of sodium chloride and 5 parts by weight of Iron oxide, the product was obtained after stirring for 20 minutes.

Embodiment 2

[0034] First add 0.5 parts by weight of acetic acid to the sludge, and stir evenly; then add 8 parts by weight of coalification agent, 4 parts by weight of sodium lignin xanthate, and 0.1 parts by weight of cellulase, and stir evenly; aging and slaking for 24 After 1 hour, granulate and serve.

[0035] The production process of the coalification agent is as follows: 75 parts by weight of waste plastics are put into a mixer, heated to 160°C, 5 parts by weight of coal tar is added, the temperature is kept at 170°C, and 5 parts by weight of dodecylbenzene polyoxyethylene is added. Ether; after 30 minutes, add 15 parts by weight of polyethylene and stir, then add 0.5 parts by weight of polypropylene after heating up to 190°C after 30 minutes, and after stirring for 30 minutes, lower the temperature to less than 22°C, then add 15 parts by weight of sodium carbonate and 15 parts by weight Parts of iron oxide, the product was obtained after stirring for 30 minutes.

[0036] The poly...

Embodiment 3

[0038] First add 1 weight part of acetic acid to the sludge, and stir evenly; then add 10 weight parts of coalification agent, 5 weight parts of sodium lignin xanthate, and 0.1 weight part of cellulase, and stir evenly; aging and slaking for 28 After 1 hour, granulate and serve.

[0039] The production process of the coalification agent is as follows: put 70 parts by weight of waste rubber into a mixer, heat to 150°C, add 4 parts by weight of coal tar, keep the temperature higher than 160°C, and add 2 parts by weight of sodium alkylbenzene sulfonate; After 25 minutes, add 10 parts by weight of polyethylene and stir. After 25 minutes, heat up to 186°C and then add 0.4 parts by weight of polypropylene. After reducing the stirring speed for 24 minutes, lower the temperature to less than 24°C, and then add 11 parts by weight of sodium chloride and 6 parts by weight of iron oxide were stirred for 26 minutes to obtain the product.

Abstract

The invention relates to a method for producing a biomass fuel by utilizing paper-making sludge and domestic sludge. The invention aims at enabling the provided method to have the characteristics of simple process flow, convenience and safety in operation and capability of reducing environmental pollution and enabling the prepared fuel to be high in combustion value and be capable of replacing coal. The technical scheme is as follows: the method for producing the biomass fuel by utilizing the paper-making sludge and the domestic sludge sequentially comprises the following steps of: 1) firstly adding 0.5-2 parts by weight of acid into the sludge and uniformly stirring; 2) then adding 8-12 parts by weight of coalification agent, 3-5 parts by weight of water-reducing agent and 0.1-0.5 part by weight of biomass enzyme and uniformly stirring; and 3) aging and curing for at least 24h, and then performing granulation.

Description

technical field [0001] The invention relates to a method for producing biomass fuel, in particular to a method for producing fuel by using papermaking sludge and domestic sludge. Background technique [0002] Papermaking sludge is the mixed sludge obtained in the primary settling tank and secondary settling tank during the biochemical treatment of paper mill wastewater; domestic sludge is the sludge deposited in urban sewage treatment plants. With the development of economic construction and the general trend of urbanization, the output of papermaking sludge and domestic sludge is increasing day by day. [0003] The traditional treatment methods for the above sludge are mainly incineration and landfill. However, landfill not only takes up valuable land resources, but also pollutes soil, groundwater and air; incineration requires large investment and operating costs, and also pollutes the air. Contents of the invention [0004] The technical problem to be solved by the pr...
