Abstract
The invention relates to a constant temperature control technology for a mining wellhead, which is suitable for anti-freezing heat preservation of wellheads of a vertical well and an inclined well in coal, metal and nonmetal mines. At present, a boiler heating mode is generally adopted for preserving heat of the wellhead by a mine enterprise. The boiler heating mode has the defects that the temperature of the wellhead cannot be automatically adjusted, the energy consumption is higher and the environmental pollution is serious. Compared with the present wellhead heat preservation technology, the constant temperature control technology has the advantages of heat preservation, anti-freezing property and functions of saving energy, protecting environment and saving cost. According to the technical scheme, a heat-preserving fan, a temperature sensor and an automatic control cabinet are arranged at the wellhead; a constant temperature control mode is adopted by the heat-preserving fan at the wellhead; by adopting the heating medium flow control and a multi-level control mode of water flow, natural negative air supply and forced air supply by the heat-preserving fan, the air temperature at the wellhead is kept at a constant temperature which is not less than 5 DEG C but not more than 7 DEG C all the time; and the temperature is adjustable, so as to meet the anti-freezing requirement of the wellhead and avoid energy waste caused by ultrahigh temperature. The constant temperature control technology for the mining wellhead is mainly used for keeping temperature of the wellhead for various big extracting enterprises of coal, mine, and the like, solving the wellhead heat preservation problem of the enterprises, lowering the operation cost of the enterprises and reducing the environmental pollution.
Description
Technical field
The present invention relates to mine well head insulation energy-saving environment-protective technical field, particularly a kind ofly make the constant well head heat-preserving constant-temperature control technology of wellhead temperature 5-7 ℃ (adjustable) through temperature inductor and automatic control switch board are set at well head.
Background technology
The mode that present bargh generally takes boiler to heat to the insulation of mine well head, it is terminal that wellhead temperature can not be realized automatic adjusting through pipeline, warm-air drier or radiator warming and heat insulation, it is bigger to consume energy.This invention technology is compared with existing mine well head heat preserving mode, can realize well head insulation demand, and energy-conserving and environment-protective save money again, make enterprise when cutting operating costs significantly, can reduce because of boiler heats the environment pollution that causes again, kill two birds with one stone.
Summary of the invention
The present invention is a kind of mine well head thermostatic control system of design.Warm-air drier or common radiator are adopted in the well head insulation, and the heating end can adopt hot water or steam heating.Through adopting the control of current or steam flow; And adopt Multistage Control patterns such as nature induced draft and forced air supply; All the time the wind-warm syndrome of keeping well head is not less than 5 ℃, is no more than 7 ℃ constant temperature, does not promptly allow wellhead temperature low excessively; Do not allow wellhead temperature too high yet, promptly satisfy the antifreeze needs of well head and prevent that simultaneously too high temperature from causing the waste of the energy.Because of well head is the negative pressure air intake, blower fan is not established the current valve, can take away a large amount of heats because of natural air inlet, simultaneously, negative pressure air intake also capable of using, the machine of realizing not blowing in can guarantee that also the part-time wellhead temperature is constant in 5 ℃-7 ℃.
Its technical scheme is: at well head heating combined fan, temperature inductor and automatic control switch board are set, when environment temperature was higher than 7 ℃, well head insulation blower fan did not start, and blower fan current valve closing is to avoid causing energy waste because of the negative pressure funnel draught; When environment temperature was lower than 7 ℃, well head blower fan current valve started one by one, through well head negative pressure transportation heat, to reduce the blower fan electric quantity consumption; When the current valve is all opened, also low 5 ℃ of wellhead temperatures, the insulation blower fan is just opened one by one, send heat with increasing, satisfies the demand that heats; When wellhead temperature surpasses 7 ℃, anti-successively orderly close-down blower fan and current valve.Wellhead temperature is adjustable, is antifreeze simultaneously, sets up defences at current valve place and freezes bypass, guarantees that the damage of current valve can freezing Fan pipeline yet.Can put forward heat with the weary wind of air source, water resource heat pump is proposed heat, municipal thermal source, all kinds of boiler interlock control, the vertical in coal, metal and the non-metal mine, inclined shaft all can be installed.
