Description
Technical field
The utility model relates to a kind of heat recovery system, particularly a kind of heat recovery system of marsh gas power generation unit.
Background technique
Biogas be organic substance under uniform temperature, humidity, pH value and anaerobic condition, through various microbial fermentations and decomposition and produce a kind of be the mixed combustible gas body of main component with methane.The content of its methane can reach 50%-70%, and methane is a kind of good clean fuel, compares with other combustion gas, and its capability of antidetonance is better.Yet the generation of biogas but needs certain temperature, and its temperature generally is to be controlled between 28 ℃-60 ℃, therefore in the ordinary course of things, particularly winter, just need heat the biogas jar.On the other hand, diesel-electric efficient is generally 30%-40%, and the energy of all the other 60%-70% has all lost with the form of heat, and wherein the heat taken away of the high-temperature flue gas of engine exhaust and inner cooling water has good use and is worth.
Summary of the invention
The purpose of the utility model just is to provide a kind of heat recovery system of marsh gas power generation unit, and the heat recovery utilization ratio is high, has overcome the inadequate problem of marsh gas power generation using energy source, has solved the heat supply problem of biogas retort simultaneously.
The technological scheme of the utility model is: a kind of heat recovery system of marsh gas power generation unit; Comprise motor, circulating water outlet and circulating water inlet; The circulating water inlet is through being connected with circulating water pump by ball valve, and circulating water pump is connected with water-to-water heat exchanger, and said water-to-water heat exchanger is connected with the motor water outlet with the motor water inlet respectively; Also comprise flue gas heat exchange device, exhaust outlet and swelling water tank; Said flue gas heat exchange device is through being connected with circulating water outlet by ball valve, and the flue gas heat exchange device also is connected with water-to-water heat exchanger, engine exhaust pipe and exhaust outlet, and said swelling water tank is connected with the motor water inlet.
As preferably, said circulating water pump is two.
As preferably, each parts all connects through water pipe, and the water pipe joint is welded to connect head through detachable bulk and connects.
Compared with prior art; The beneficial effect of the utility model is: the use of water-to-water heat exchanger, flue gas heat exchange device; Add circulating water pump, form a simple circulatory system, make the heat recovery utilization ratio high; Overcome the inadequate problem of marsh gas power generation using energy source, solved the heat supply problem of biogas retort.Swelling water tank is connected with the motor water inlet, guarantees engine interior circuit pressure and quantity of circulating water, makes the engine reliable operation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the process flow diagram of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Heat recovery system like Fig. 1 or a kind of marsh gas power generation unit shown in Figure 2; Comprise motor, circulating water outlet 10 and circulating water inlet 9; Circulating water inlet 9 is through being connected with circulating water pump 5 by ball valve 4, and circulating water pump 5 is connected with water-to-water heat exchanger 6, and said water-to-water heat exchanger 6 is connected with the motor water outlet with the motor water inlet respectively; Also comprise flue gas heat exchange device 1, exhaust outlet 11 and swelling water tank 8; Said flue gas heat exchange device 1 is through being connected with circulating water outlet 10 by ball valve 4, and flue gas heat exchange device 1 also is connected with water-to-water heat exchanger 6, engine exhaust pipe and exhaust outlet 11, and said swelling water tank 8 is connected with the motor water inlet.As preferably, said circulating water pump 5 is two; Each parts all connects through water pipe, and the water pipe joint is welded to connect 7 connection through detachable bulk.
The utility model adopts double water pump, a water pump commonly used and a reserve pump, the reliable operation of the assurance circulatory system.Swelling water tank 8 is connected with the motor water inlet, guarantees engine interior circuit pressure and quantity of circulating water, makes the engine reliable operation.The whole system parts are integrated to be installed on the support 2, makes installation and keeps in repair convenient.
Outer loop water flow to water-to-water heat exchanger 6 through circulating water pump 5, with the high temperature coolant generation heat exchange of engine interior cool cycles.Hot water after the exchange flows in the flue gas heat exchanger 1 again, carries out heat exchange with the engine high-temperature flue gas, thereby the biogas jar is heated to the user from circulating water outlet 10 water outlets at last.The gas of engine interior can directly be discharged through exhaust outlet 11.
