Abstract
The utility model discloses a kind of energy-saving ammonia raw material moulded coal drying system, solve the problem that energy resource consumption is many and potential safety hazard is large that existing moulded coal drying system exists.Comprise air blast (2) and drying furnace for formed coal (3), the air intake vent of air blast (2) is connected with boiler flue intake line (6), the air outlet of air blast (2) is communicated with the air intake vent of drying furnace for formed coal (3), the air outlet of drying furnace for formed coal (3) is connected with air-introduced machine (4), the air outlet of air-introduced machine (4) is connected with the chimney (5) with deduster.The utility model utilizes the flue gas low-grade remaining heat of boiler to dry moulded coal, gets final product fuel saving coal, turn eliminates the natural potential safety hazard of moulded coal.
Description
Technical field
The utility model relates to a kind of drying system of moulded coal, particularly a kind of drying system of the gas-making type coal as Ammonia Production raw material.
Background technology
With adhesive, anthracite fine coal is processed into moulded coal, substitutes anthracite block coal and be widely used as Ammonia Production raw material.Generally coal-fired hot-blast stove is all adopted to be that thermal source is dried after briquette molding, the bunker coal that moulded coal per ton consumes about 40 kilograms.This furnace drying method, not only lot of energy, and Mars is easily brought in drying oven by coal-fired hot-blast stove, and cause the moulded coal in drying oven to catch fire, potential safety hazard is larger.
Summary of the invention
The utility model provides a kind of energy-saving moulded coal drying system, solves the technical problem that energy resource consumption is many and potential safety hazard is large that existing moulded coal drying system exists.
The utility model solves above technical problem by the following technical programs:
A kind of energy-saving moulded coal drying system, comprise air blast and drying furnace for formed coal, the air intake vent of air blast is connected with boiler flue intake line, the air outlet of air blast is communicated with the air intake vent of drying furnace for formed coal, the air outlet of drying furnace for formed coal is connected with air-introduced machine, the air outlet of air-introduced machine is connected with the chimney with deduster.
The air intake vent of air blast is connected with hot-blast stove.
The utility model utilizes the flue gas low-grade remaining heat of boiler to dry moulded coal, gets final product fuel saving coal, turn eliminates the natural potential safety hazard of moulded coal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of energy-saving moulded coal drying system, comprise air blast 2 and drying furnace for formed coal 3, the air intake vent of air blast 2 is connected with boiler flue intake line 6, the air outlet of air blast 2 is communicated with the air intake vent of drying furnace for formed coal 3, the air outlet of drying furnace for formed coal 3 is connected with air-introduced machine 4, the air outlet of air-introduced machine 4 is connected with the chimney 5 with deduster.
The air intake vent of air blast 2 is connected with hot-blast stove 1.Synthetic ammonia feedstock gas-making type coal is all generally in hot-blast stove 1, produced the hot-air of 130 degree by bunker coal and air blast, then sends into drying furnace for formed coal 3 by air blast 2, is dried by the moulded coal containing 10% moisture of having an appointment, makes briquette strength reach 60-65N requirement.The general ton moulded coal of the method needs about 40 kilograms, consume fuel coal.And the boiler flue of Ammonia Production device of the present utility model will after electric cleaner dedusting meet the requirement of environmental protection, for preventing the moisture in flue gas from separating out in low temperature, damage deduster, General Requirements deduster inlet flue duct temperature degree is at 150 degree.Have the flue gas of the low temperature exhaust heat reaching 130 degree to pass through smoke stack emission through deduster rear pass gas.The utility model is the hot-air utilizing the low temperature exhaust heat of the boiler flue intake line 6 emitted to substitute hot-blast stove 1 generation, dries moulded coal.A moulded coal factory year producing 100000 tons per year can about 4000 tons, fuel saving coal.
Claims (2)
1. an energy-saving ammonia raw material moulded coal drying system, comprise air blast (2) and drying furnace for formed coal (3), it is characterized in that, the air intake vent of air blast (2) is connected with boiler flue intake line (6), the air outlet of air blast (2) is communicated with the air intake vent of drying furnace for formed coal (3), the air outlet of drying furnace for formed coal (3) is connected with air-introduced machine (4), the air outlet of air-introduced machine (4) is connected with the chimney (5) with deduster.
2. one according to claim 1 energy-saving ammonia raw material moulded coal drying system, is characterized in that, the air intake vent of air blast (2) is connected with hot-blast stove (1).
