Description

A kind of aerobic fermentation compost air supply system

Technical field

This utility model relates to a kind of air supply system, particularly relates to a kind of aerobic fermentation compost air supply system.

Background technology

Along with quickening and the expansion agriculture, livestock and poultry cultivation scale of China's city process, the generation amount of the organic waste such as municipal sludge, feces of livestock and poultry increases day by day. It is estimated that the feces of livestock and poultry amount that China produces every year is up to 3,000,000,000 tons, sludge quantity reaches more than 200,000,000 tons. Aerobic fermentation compost treatment be realize that organic waste is innoxious, the effective way of minimizing and resource. In aerobic fermentation composting treatment process, the supply that ventilates is the essential condition realizing organic waste aerobic fermentation compost. There are some researches show, aerobic fermentation compositing system treatment effeciency and quality are had material impact, suitable air quantity and pathogenic wind-warm to not only help shortening composting cycle by ventilation volume and pathogenic wind-warm, and are favorably improved composting production quality.

At present, the following problem of aerobic fermentation compost air supply system ubiquity: (1) only has ventilation volume to control, it does not have pathogenic wind-warm controls. Existing aerobic fermentation compost air supply system is general to be only controlled the air quantity entering fermentation tank, owing to Various Seasonal pathogenic wind-warm changes greatly, and particularly northern area, usually because fermentation temperature is too low, cause that aerobic fermentation compositing system cannot normally start. (2) pathogenic wind-warm and air quantity individually control. Part Experiment room aerobic fermentation compost air supply system first controls pathogenic wind-warm, then regulates air quantity, due to independent control, there is system complex and complex operation problem, and gas volume temperature influence is huge simultaneously, causes that Boiler pressure control precision is low. (3) automaticity is not high. Existing aerobic fermentation compositing system ventilation pathogenic wind-warm and air quantity many employings manual adjustments, and cannot require automatically to adjust according to environmental change or aerobic fermentation compositing system after setting, cause complex operation, control accuracy low and hand labor input amount is big.

Summary of the invention

For the problems referred to above, the purpose of this utility model is to provide a kind of aerobic fermentation compost air supply system, is not only able to be effectively improved automaticity and control accuracy, and can realize aerobic fermentation compositing system pathogenic wind-warm and Boiler pressure control simultaneously.

For realizing above-mentioned technical purpose, this utility model takes techniques below scheme: a kind of aerobic fermentation compost air supply system, and it includes a source of the gas, a flow regulator, a gas flowmeter, a gas heater, a temperature sensor and a controller;Described source of the gas connects an aerobic fermentation tank by a trachea, and described trachea is sequentially connected in series described flow regulator, gas flowmeter, gas heater and temperature sensor; The input of described controller connects described temperature sensor and gas flowmeter respectively, and the outfan of described controller connects described flow regulator and gas heater respectively.

Described source of the gas adopts air pump.

Described flow regulator adopts ball valve.

Described controller adopts the controller with man machine interface.

This utility model is owing to taking above technical scheme, it has the advantage that this utility model is owing to arranging gas flowmeter and the endotracheal gas flow of temperature sensor Real-time Collection and gas temperature, and control flow regulator and gas heater in real time so that endotracheal gas temperature and gas flow reach the pathogenic wind-warm needed for aerobic fermentation compost and air quantity by controller, therefore it is not only able to be effectively improved automaticity and control accuracy, and is capable of control realization pathogenic wind-warm and air quantity simultaneously. This utility model disclosure satisfy that organic waste aerobic fermentation compost requirement under low temperature environment, there is simple in construction and the low advantage of cost simultaneously, it is possible to be widely used in carrying out in the aerobic fermentation composting test research of the organic waste such as municipal sludge, feces of livestock and poultry and industrial processes.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is principle schematic of the present utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is described in detail.

As it is shown in figure 1, aerobic fermentation compost air supply system of the present utility model includes source of the gas 1, trachea 2, flow regulator 3, gas flowmeter 4, gas heater 5, temperature sensor 6 and a controller 7;

Source of the gas 1 connects one end of trachea 2, and trachea 2 is sequentially connected in series flow regulator 3, gas flowmeter 4, gas heater 5 and temperature sensor 6, and the other end of trachea 2 connects aerobic fermentation tank 8;

The input of controller 7 connects temperature sensor 6 and gas flowmeter 4 respectively, and the outfan of controller 7 is connection traffic actuator 3 and gas heater 5 respectively.

In a preferred embodiment, source of the gas 1 can adopt air pump.

In a preferred embodiment, flow regulator 3 can adopt ball valve.

In a preferred embodiment, controller 7 can adopt the controller with man machine interface, in order to user's input gas temperature and gas flow parameter value.

The use procedure of aerobic fermentation compost air supply system of the present utility model is described in detail below in conjunction with specific embodiment:

As in figure 2 it is shown, first, source of the gas 1 is opened so that the gas that source of the gas 1 produces enters in aerobic fermentation tank 8 by trachea 2; Then, according to environmental change, it is judged that aerobic fermentation compost desired gas temperature and gas flow, and required gas temperature and gas flow parameter value are inputted to controller 7 by man machine interface; Meanwhile, the gas flow signals in the trachea 2 that the gas temperature signal in the trachea 2 of its collection and gas flowmeter 4 are gathered by temperature sensor 6 is transferred to controller 7 respectively; Finally, controller 7 distinguishes corresponding adjustment gas heater 5 and flow regulator 3 according to the gas temperature needed for the aerobic fermentation tank 8 of input with gas flow parameter value gas temperature signal and the gas flow signals that gas flowmeter 4 transmits in conjunction with temperature sensor 6 transmission so that gas temperature and flow in trachea 2 reach the pathogenic wind-warm needed for aerobic fermentation compost and air quantity.

Above-described embodiment is merely to illustrate this utility model; wherein the structure of each parts, connected mode and processing technology etc. all can be varied from; every equivalents carried out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
