At present; the big-and-middle-sized biogas engineering of scale is increasing both at home and abroad; particularly high concentration material intermediate temperature anaerobic fermentation is the trend of scale biogas engineering development; if make the long-term stable operation of high concentration material biogas mesophilic digestion engineering; keep constant, efficient gas production; with regard to needing a large amount of heats to heat fermentation tank, fermentation temperature is not changed with ambient air temperature.
The combustion gas Biogas Generator Set that big-and-middle-sized biogas engineering is supporting, more than the power ratio useful work of exhaust heat and cooling water loss. The exhaust heat and the cooling water heat resource that account at present nearly 55% heat energy of gas engine fuel are wasted substantially, and energy-conservation, consumption reduction improves energy utilization rate and more and more comes into one's own at home, and the utilization of combustion gas biogas generator fume afterheat is inexorable trend.
At present the supporting Biogas Generator Set of biogas engineering is also supporting, and waste heat boiler reclaims heat in unit exhaust, waste heat boiler is heated to be steam water interface by the saturation water of steam-water separator and gets back to steam-water separator and carry out carbonated drink separation and produce the saturated vapor amount (184 DEG C of saturation temperatures) of 1.0MPa, the hot user of steam supply. Fermentation tank normally moves the hot water that needs a large amount of 70 DEG C of left and right, and the situation variation with input and output material in tank with hot water time and consumption, so anaerobic fermentation system has configured large-scale hot water storage tank. Hot water in hot water storage tank is produced by vapor heat exchanger, and according to the operation of hot tank temperature control system control vapor heat exchanger with stop.
There is following shortcoming in above-mentioned prior art:
(1) in biogas engineering, need to configure independent vapor heat exchanger, utilization rate of waste heat is low, and increases construction costs;
(2) biogas engineering need to configure large-scale hot water storage tank, and cost is high, and floor space is large, safeguards that use is more complicated.
Summary of the invention
The present invention is directed to above-mentioned technical problem, design a kind of biogas engineering fast-module-packaging blocking residual heat using device, without configuration hot water storage tank, reduce construction costs, improve fume afterheat utilization rate.
To achieve these goals, the present invention adopts following technical scheme:
A kind of biogas engineering fast-module-packaging blocking residual heat using device, comprise fermentation tank and biogas generator, the flue outlet of described biogas generator is connected with the input of heat exchanger, the hot water outlet of described fermentation tank is connected with the input of described heat exchanger, and the output of described heat exchanger is connected with the input of fermentation tank.
Further, described heat exchanger is needle-tube afterheat heat exchanger.
Further, described needle-tube afterheat heat exchanger is fast-module-packaging blocking needle-tube afterheat heat exchanger.
Further, the flue outlet of described biogas generator is connected with the input of described fast-module-packaging blocking needle-tube afterheat heat exchanger by gas bypass pipeline valve, and described fermentation tank is connected with the input of described fast-module-packaging blocking needle-tube afterheat heat exchanger by hot water circulating pump.
Further, also comprise waste heat boiler; The input of described waste heat boiler is connected with the flue outlet of described biogas generator.
The present invention introduces fast-module-packaging blocking needle-tube afterheat heat exchanger in big-and-middle-sized biogas engineering, adopt fast-module-packaging blocking UTILIZATION OF VESIDUAL HEAT IN technology, not only greatly promote biogas engineering overall technology level, and be a kind of a kind of approach and practicable method that solves fermentation tank heating and heat preservation, expends energy problem. The present invention has following beneficial effect:
(1) optimize form anaerobic fermentation methane engineering process;
(2) adopt the high pin type heat exchange of heat pipe of novel heat exchange efficiency, improve fume afterheat utilization rate;
