Embodiment 1

[0045] This embodiment discloses a method for temperature-controlled turning and chopping of biomass fuel in an open-air stockyard, such as figure 1 shown, including the following steps:

[0046] Step 1: Monitor and record the entry of fuel, and stack it according to regulations and categories;

[0047] After the fuel supplier transports the fuel to the stockyard, it will monitor the transported fuel and make monitoring records, including fuel type, quantity, calorific value, water content, ash, etc., and make records;

[0048] According to the monitoring data, the newly collected fuel is stacked and stored according to the regulations.

[0049] Step 2: After the stockpile is stable, monitor the temperature and humidity of the center of the stockpile, and monitor the surrounding environmental data at the same time;

[0050]After the stacking is completed and the stockpile is stable, the humidity of the fuel stockpile is measured by air flow drying method, microwave drying me...

Embodiment 2

[0066] The purpose of this embodiment is to provide a system compatible with the temperature-controlled turning and chopping heat dissipation method of the biomass field in the first embodiment.

[0067] As an example to achieve the above purpose, this embodiment provides a temperature-controlled turning and chopping heat dissipation system for a biomass field, including a client, a server, and multiple temperature sensors connected to the server for monitoring the stacking center and the surrounding environment and multiple humidity sensors. The server includes a memory, a processor, and a computer program stored on the memory and operable on the processor, and the processor implements the following steps when executing the program:

[0068] (1) receiving the monitoring data sent by the temperature sensor and the humidity sensor;

[0069] (2) According to the preset estimation model, calculate the estimated time for the stockpile to heat up to the critical carbonization temp...

Embodiment 3

[0079] The purpose of this embodiment is to provide a computer-readable storage medium.

[0080] A computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the following steps are performed:

[0081] (1) receiving the monitoring data sent by the temperature sensor and the humidity sensor, the monitoring data including the stacking center and surrounding environment data;

[0082] (2) According to the preset estimation model, calculate the estimated time for the stockpile to heat up to the critical carbonization temperature;

[0083] (3) Optimizing the monitoring time arrangement of the stockpile center temperature before turning over and chopping according to the estimated time, and carrying out temperature monitoring reminders at the corresponding monitoring time;

[0084] (4) Determine the chopping time according to the acquired monitoring data, and carry out a chopping reminder at the corresponding chopping t...

Abstract

The invention discloses a method and system for temperature control pile overturning and heat dissipation of biomass fuel on an open-air material yard. The method includes step (1) of monitoring and recording fuel entry into a yard, and stacking according to the regulations; step (2) of monitoring moisture, temperature and impurities of a material pile; step (3) of calculating estimated time for the material pile to be heated to a critical carbonization temperature according to a preset estimation model; step (4) of optimizing a time schedule of temperature monitoring of the material pile center before the overturning according to the estimated time; step (5) of determining the pile overturning time according to the monitoring data of the material pile, and performing the overturning during the overturning time; and step (6) of repeating steps (2)-(5) after each overturning is completed until the material pile humidity meets the use requirements. The method and system are suitable forthe management of large-scale open-air biomass fuel, and the problem that all kinds of biomass fuels adopt the same monitoring standard, which wastes time and labor and is not implemented properly issolved.

Description

technical field [0001] The invention belongs to the field of biomass fuel management, and in particular relates to a method and system for temperature-controlling, chopping, and cooling of biomass fuel in an open-air stockyard. Background technique [0002] Using various agricultural, forestry, construction, and industrial waste biomass as fuel, its renewable and low-emission characteristics are very in line with the current environmental protection situation and energy reform situation. As a kind of biomass energy, it has the advantages of wide source of raw materials, renewable, and cleaner than coal. Biomass briquettes are generally not used immediately after production, and need to be stored in the factory for several months or be used after long-distance transportation. During the storage of a large amount of biomass briquettes, a large amount of heat is generated due to oxidation, which increases the storage temperature, and there is a risk of spontaneous combustion. ...
