Abstract

The utility model discloses a waste heat recycling system of circulating water of a marsh gas generating set, comprising an engine, water mixing valves, a hot water pool, a hot water pump, a cold water pump and a water return pool. The waste heat recycling system is structurally characterized in that cooling and circulating hot water of the engine is connected to the hot water pool; the hot waterin the hot water pool and the cold water in the water return pool are respectively pumped by the hot water pump and the cold water pump, are connected to the water mixing valve for mixing, and then are conveyed to the facilities needing to be heated by pipelines, and the cooling water is discharged after passing through the facilities needing to be heated and then backflows to the water return pool; and the cold water in the water return pool and the hot water in the hot water pool are connected to another water mixing valve for mixing and then enter into the engine. The waste heat recycling system solves the problem that the temperature-rising work of the marsh gas engine is not stable, ensures the requirements of heat balance when the marsh gas engine is in work, simultaneously and fullyutilizes large amount of heat energy when the engine is in work, provides insulation for the piglets in a piggery, increases the survival rate of the piglet, fully recycles the waste heat of circulating water of the generating set and achieves the purposes of energy recovery and resource recycling.

Description

Marsh gas power generation unit circulating water waste heat utilizes system again
Technical field:
The utility model belongs to marsh gas power generation unit circulating water application, especially belongs to a kind of marsh gas power generation unit circulating water waste heat and utilizes system again.
Background technique:
Usually small power generation unit engine cooling is a pump circulation water cooling system, promptly utilize water pump to improve the pressure of cooling liquid, force the radiator of cooling liquid, under the cooling fan positive action through front end, air passes through outside radiator core, and the cooling liquid of heat is owing to turning cold to the air heat radiation.Because methane fuelled engine temperature rise when work is very high, adopts enclosed pump circulation water cooling mode, this just essential volume that strengthens radiator.Just can reach the cooling effect of expection.And the open type water-cooling pattern, the difficult control of temperature of engine cooling water, this has also influenced the motor proper functioning.The a large amount of heat energy that produce in the thermal process that motor looses are not well utilized simultaneously.In order to satisfy the national environmental protection and the requirement of renewable sources of energy policy, reach the purpose of energy-saving and emission-reduction.The waste heat that makes full use of engine cooling circulating water heats to other facility, has improved utilization efficiency of energy and comprehensive benefit.It is problem to be solved in the utility model.
Summary of the invention:
The purpose of this utility model is, overcome the shortcoming of prior art, provide a kind of marsh gas power generation unit circulating water waste heat to utilize system again, it is very high to have solved the temperature rise of marsh gas power generation unit methane fuelled engine when work, the problem of job insecurity, the flat demand of filling weighing apparatus of heat when guaranteeing methane fuelled engine work, a large amount of heat energy that produce when making full use of engine operation simultaneously; Reach the purpose of energy recovery and resource reutilization.
The purpose of this utility model is achieved in that described marsh gas power generation unit circulating water waste heat utilizes system again, comprise motor, mix water valve, hot-tub, hot water pump, water supply pump and back pool, its structural feature is that the cool cycles hot water of motor is received hot-tub, the hot water of hot-tub comes out by water supply pump by the cold water in hot water pump and the back pool, receive mix water valve mix the back by line transportation to needs heating facility, be back to back pool through the cooling water that needs to come out behind the heating facility; Cold water in the back pool is received with the hot water of hot-tub and is entered motor after another mixed water valve mixes.
Advantage of the present utility model: the utility model has solved the problem of methane fuelled engine temperature rising job insecurity, thermally equilibrated demand when guaranteeing methane fuelled engine work, the a large amount of heat energy that produce when making full use of engine operation simultaneously reach the purpose of energy recovery and resource reutilization.Because for motor provides good heat radiation cooling system, thereby thermally equilibrated demand when having satisfied engine operation, make engine operation more stable, biogas output through the mathane generating pool after the heating of engine cycles water obviously increases, for generator set provides more sufficient fuel, guaranteed the uninterrupted continuous operation of generator set.For the pig house piggy provides insulation, increased the survival rate of piggy simultaneously, made the circulating water waste heat of generator set obtain utilizing again fully.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: motor 1, mix water valve 2, hot-tub 3, hot water pump 4, water supply pump 5, back pool 6, mathane generating pool 7, pig house piggy heat insulating bed 8.
Embodiment:
Below in conjunction with drawings and Examples structure of the present utility model is elaborated:
As shown in Figure 1, marsh gas power generation unit circulating water waste heat described in the utility model utilizes system again, by motor 1, mixed water valve 2, and hot-tub 3, hot water pump 4, water supply pump 5, back pool 6 several sections such as grade are formed.Deleted the radiator that former engine cooling is simultaneously, cooling fan.The hot water storage that the circulatory system utilizes motor to produce arrives hot-tub, hot water by hot water pump be transported to lead to need the heating facility as: after mathane generating pool and pig house piggy are heat insulating bed, cooling water is back to back pool, enter motor more again with after the hot water of hot-tub mixes, finish a circulation, its structural feature is that motor 1 cool cycles hot water is received hot-tub 3, the hot water of hot-tub 3 comes out by water supply pump 5 by the cold water of 6 li of hot water pump 4 and back pools, be adjusted to 55 ℃ hot water through overmulling water valve 2, by line transportation to needs heating facility as: mathane generating pool 7 and pig house piggy heat insulating bed 8 are heated; Give mathane generating pool and the pig house piggy is heat insulating bed after heating cooling water is back to back pool 6, another mixed water valve of hot water process with hot-tub 3 outflows, mixing enters motor 1 after regulating and becoming 50 ℃ water again, provide good heat radiation cooling to motor, thereby thermally equilibrated demand when having satisfied engine operation, make engine operation more stable.
Whole workflow explanation:
1. after the engine start, motor is heating up gradually, and cooling water is along with the temperature of motor has been raised to the unlatching temperature (this temperature is after 80 degrees centigrade usually) of thermostat, and cool cycles hot water comes out to enter hot-tub 3 from motor 1.
2. the hot water of 3 li of hot-tubs comes out by water supply pump 6 by the cold water of 5 li of hot water pump 4 and back pools, is adjusted to 55 ℃ hot water through overmulling water valve 2, heats to mathane generating pool 7 and pig house piggy heat insulating bed 8 by line transportation.
3. give mathane generating pool and the pig house piggy is heat insulating bed after heating cooling water is back to back pool 5, with the hot water of hot-tub through the overmulling water valve, mix to regulate entering motor 1 again after becoming 50 ℃ water.Finish a work cycle.
