Temperature monitoring and energy saving control system of closed coal bunker

Abstract

The invention relates to a closed coal bunker temperature monitoring and energy-saving regulating controlling system, and particularly temperature energy-saving regulating controlling is conducted through a ground source heat pump, and the problem of bunker temperature regulating controlling is solved through a sustainable and environmental protection method. The closed coal bunker temperature monitoring and energy-saving regulating controlling system comprises a water pump, a pressurizing device, a valve, a temperature measuring device, a cooling device, heat exchanger pipe network hoisting protective devices, coal bunker internal heat exchanger pipe networks, a heating device and a coal bunker outlet heating pipe network. The internal temperature of a coal bunker can be effectively reduced, and the situation that the water content of a coal body is greatly increased through a watering cooling method does not occur. The water content of the coal body in a coal bunker outlet can be effectively reduced, the temperature of the coal bunker in the coal bunker outlet is increased, the probability of blocking in the coal bunker outlet is reduced, and the possibility of freezing in winter is avoided. Groundwater is adopted to serve as a cold and heat source, the production cost of enterprises is not significantly increased while the functions of energy saving and environmental protection are achieved, better universality is achieved, and the system can be expanded to be used in other enterprises apart from the coal bunker.

Description

technical field [0001] The invention relates to a temperature monitoring and energy-saving control system of a closed coal bunker, in particular, a ground source heat pump is used for temperature energy-saving regulation, and sustainable environmental protection means are used to solve the temperature control problem of the coal bunker. Background technique [0002] Coal bunker is the main coal storage equipment for coal enterprises and thermal power plants, and the temperature parameter of its internal coal body is an important indicator to measure its safety. On the one hand, the location near the center of the coal bunker will cause heat accumulation due to its airtight environment and coal’s spontaneous combustion characteristics, which will accelerate the oxidation of scattered coal and even lead to coal bunker fire accidents. On the other hand, after the coal is mined from the ground, it needs to go through a series of processes such as washing, desulfurization, etc., ...

Problems solved by technology

[0004] The invention relates to a closed coal bunker temperature monitoring and energy-saving control system. The system uses groundwater as a cold and heat source, and solves the problem of coal bunker temperature and heat regulation through heat exchange; On the other hand, increase the temperature of the raw coal at the exit of the coal bunker to solve the problems of high moisture content in the coal and freezing at the exit in winter
