Room as with materials such as reinforcing bars being built into house using sandstone cement.There are Yishanmen and a fan window in room.Room Between the thick insulation sponges of 5CM are sticked on wall (window does not have to patch insulation sponge, but is thermally shielded insulation by multilayer heavy sheet glass).This Sample is just by insulation sponge row into a closed keeping warmth space, referred to as moist closet 10.And spread iron on floor in moist closet 10 Plate, to increase the hardness on ground and wearability.

The 2nd, facilities control console 62 is installed：

Heat exchanger is fixed on the wall, and heat energy dispatch tube is connected to outdoor.Blower fan or fan 622 are hung up properly on the wall, And connect power line.Camera 623 is hung up properly on the wall, and connects signal wire and power line.Power-supply controller of electric is connected to outdoor Facilities control console 62, when can manually or automatically control various equipment by facilities control console 62, and operate, manually be more than from Dynamic priority.The electric former line of the signal wire of all devices is all summarized in facilities control console 62, equipment corresponding to another termination.If All signal wires of standby console 62 access supervisory control desk 61 indirectly again, pass through the data of reception and corresponding by supervisory control desk 61 Set and carry out software control.

The 3rd, security control console 63 is installed：

The signal wire of all sensors is all summarized in security control console 63, sensor corresponding to another termination.Safety control All signal wires of platform 63 processed access supervisory control desk 61 indirectly again, by data of the supervisory control desk 61 by reception and corresponding setting Carry out software control.Temperature before being read such as Temperature Humidity Sensor 634 is 36 degree, now sets the operating temperature of moist closet 10 as 35 Degree, positive and negative 1 degree of deviation.The signal wire that so current actual temperature value first passes through sensor passes to security control console 63, then from Security control console 63 passes to supervisory control desk 61, and the CPU of supervisory control desk 61 has read multichannel (raising accuracy in detection) temperature as 36 Degree, then compared with 35 degree of the benchmark of setting, and deviation has had 1 degree, just stops heat pump work at once, stops heat energy and is sent into Heat exchanger 621.When sensor detects that actual temperature is less than 34 degree, it is low that the CPU of supervisory control desk 61 has read multi way temperature In 34 degree, restart heat pump work, heated to moist closet 10.

The 4th, gas console 64 is installed：

Primarily to ensure the normal collection of gas.The blowing mouth of fermentation tank 21 is directly or indirectly connected to gas console 64.Such as flowmeter 642 of having been connected among the airway tube 51 of every fermentation tank 21, the methane quantity with detection outflow is how many.Stream For the can of scale 642 on gas console 64, operating personnel can easily see each hair in gas console 64 The traffic conditions of fermentation tank 21, if wherein one is broken down, as air guide tank blocks.The flowmeter 642 on so this road does not just have Or only very little flow.Moreover, can also cause the pressure anomaly in fermentation tank 21 simultaneously, the CPU of supervisory control desk 61 detects this After a little abnormal datas, alarm will be started.Remind staff.

The 5th, supervisory control desk 61 is installed：

Facilities control console 62, security control console 63, the data wire of gas console 64, signal wire or power line, all directly Or supervisory control desk 61 is connected to indirectly.In order to maintain normal work, operation condition of work is first set to system.The parameter of setting can With by mouse, keyboard, button, touch screen input, by LCD, LED output signals or display data and image.Pass through relay Device or controlling switch control the automatic work of each equipment, set judgement and treatment conditions by special-purpose software, pass through acousto-optic Alarm to remind staff's timely processing failure；Sensing data, flow number are preserved by storage mediums such as hard disk, USB flash disks According to various beneficial datas such as the, working conditions of time data, each fermentation tank 21.And can by the comparison of these data, analysis, Count, so as to be handled and improved accordingly, collecting methane system is worked in the best condition.

6th, set during work and automatically control parameter：

For example the biogas of how many flow is set, just start work, be just stopped less than how many flow.And all numbers According to being associated, intellectual analysis can be carried out by software.So as to realize that system is automatic, intelligently works.

7th, load fermentation raw material and enter fermentation tank 21：

Biogas slurry raw material is pumped into fermentation tank 21 with excrement machine is taken out.Cover the inner ring of lid 213.Fermentation tank 21 is loaded vapour in batches Car, it is transported to outside moist closet 10.

8th, the blending raw materialses of fermentation tank 21：

The inner ring of lid 213 on each fermentation tank 21 is opened, fermenation raw liquid is blent, such as adds other a certain amount of raw materials Such as green grass, a certain amount of zymophyte etc. is added.Fermenation raw liquid is namely set to be in preferable yeastiness.

9th, fermentation tank 21 is installed on fixed mount 41, the inner ring of lid 213 (being free of agitator 30) is covered again, with fork truck handle Fermentation tank 21 is transported on fixed mount 41 and fixed.

10th, push away fixed mount 41 and arrive moist closet 10, then be fixed on agitation platform 40, can so better profit from space.

11st, airway tube 51 in connection, and make safety test：

The delivery outlet of every fermentation tank 21 is transferred on corresponding airway tube 51, while connects safety valve 22, airmeter, Air gauge etc..Safety test before being produced again.The seal of airway tube 51 and fermentation tank 21 is such as tested, checks various sensings The working condition of device, check the arrange parameter of supervisory control desk 61.This is the preparation before production.

12nd, startup heat pump works to heat and enter to moist closet 10 and automatically controlled：Work as everything in readiness, close good insulation The door and window of room 10.Operating switch is opened, formally into working condition.

13rd, aerogenesis and in real time dynamically recording various parameters are started：When various equipment all enter working condition, sensor detection To data be constantly sent to host CPU.CPU is tested by running special-purpose software, record, analyzing and processing data.

If the 14, midway wherein certain fermentation tank 21 break down, directly closing corresponding to switch valve 53, connect standby lead Tracheae 51, either directly change the faulty component of fermentation tank 21 or the fermentation tank 21 of failure is moved out to outside moist closet 10.

15th, after the completion of collecting biogas, to waste heat recovery, can be raised with normal temperature coolant-temperature gage to absorb the heat in moist closet, Fermentation tank 21 is removed outside moist closet 10 again.Collecting methane through excessive day, collecting methane time are over.So it is shut off All working switchs, and cuts off working power, stops collecting methane process.Airway tube 51 is pulled out, fixed mount 41 is released insulation Room 10.

16th, fermentation tank 21 is moved on carrier by fork truck again.

17th, directly applied fertilizer in farmland：

Automobile transports the fermentation tank 21 equipped with biogas residue near farmland.Open the slag notch 219 of a fermentation tank 21 Sealing plate, the valve of deslagging flexible pipe 216 are opened, force (forcing) pump in concatenation, then concatenate slag-discharging device 23, and the opposite farmland in outlet. Automobile is started, opens force (forcing) pump, automobile side opens side to farmland fertilization, while also gradually empties fermentation tank 21.

18th, after emptying fermentation tank 21, then automobile with reaching marsh gas raw materials charging feedstock.

19th, so circulation.Complete industrialization collecting methane process.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
