Description
Technical field
The utility model belongs to heating agent source hot air heating system technical field, and what relate generally to is a kind of coal mine well port storage heater, is applicable to all heating agent sources hot air heating system.
Background technology
Energy Management Contract (EPC-Energy Performance Contracting) is a kind of novel market-oriented power-saving mechanism.Its essence is exactly the energy-conservation trafficwise that the energy cost that reduces is used for paying Energy-saving Projects complete cost.Energy-saving and emission-reduction, reserved resource is the inevitable direction of enterprise development.Coal mining is an industry consuming the energy, a lot of equipment of its configuration are (as air compressor unit, gas electricity unit etc.) being in operation to produce a large amount of high-temperature residual heats---i.e. heating agent, these heats effectively being used by saving very large cost, such as these heats being used coal mine well port and can solve winter or the antifreeze problem of cold district pithead low temperature.At present, the antifreeze problem of coal mine well port adopts electrical heating blower fan mode mostly, direct electricity consumption drive electric heater adds hot air and then blows to well head by blower fan, prevent well head freezing, the subject matter of this mode is: waste a large amount of electric energy and the application life of electric heating tube low, add cost of production.In order to can allow produce in the high-temperature residual heat that generates effectively utilize and save electric energy, original electrical heating unit is changed to heating medium for heating air, make wellhead temperature remain at 2 ° of more than C, prevent from well head from freezing or fall ice etc. hindering safe accident generation.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to propose a kind of coal mine well port storage heater.Better solve the problem that existing hot blast electric heater unit cost of production is high, reach and increase coal mine well port heat exchange area, improve heat exchange efficiency, save energy consumption, reduce use cost and the object making wellhead temperature constant all the time.
The technical scheme that the utility model realizes above-mentioned purpose employing is: a kind of coal mine well port storage heater is primarily of PLC, frequency conversion fan, hot blast unit leaving air temp sensor, well head mixing air temperature sensor and heat medium temperature control valve composition, described hot blast unit leaving air temp sensor is arranged on the air outlet position of hot blast unit, described well head mixing air temperature sensor is arranged on coal master's well head position, described frequency conversion fan is arranged on hot blast unit air intake position, heat medium temperature control valve valve body with enter heating agent pipeline and be connected, the electric executing agency of heat medium temperature control valve is connected with PLC, PLC respectively with hot blast unit leaving air temp sensor, well head mixing air temperature sensor, frequency conversion fan, heat medium temperature control valve connects.
What hot blast unit leaving air temp sensor described in the utility model adopted is PT100 thermal resistance.
What well head mixing air temperature sensor described in the utility model adopted is PT100 thermal resistance.
The utility model is owing to arranging storage heater at coal mine well port, by carrying out stepless time adjustment control to blower fan, realize running at low ambient temperatures heating, and the frequency conversion fan of hot blast unit is run between a minimum value and a maximum value, ensure that wellhead temperature controls (to remain at 2 ° of more than C) in a rational temperature range, effectively increase heat exchange area, improve heat exchange efficiency, reduce energy consumption, save the energy.Solve the antifreeze problem of cold district pithead low temperature, making ice or pendant ice etc. hinder safe accident and occur.

Detailed description of the invention
Composition graphs 1, provides embodiment of the present utility model as follows:
As shown in Figure 1, the novel described coal mine well port storage heater of this enforcement is arranged in the main shaft mouth of mine and the hot blast machine room of auxiliary shaft mouth.It forms primarily of PLC 1, frequency conversion fan 2, hot blast unit leaving air temp sensor 3, well head mixing air temperature sensor 4 and heat medium temperature control valve 5.What hot blast unit leaving air temp sensor 3 adopted is PT100 thermal resistance, and it is arranged on the air outlet position of hot blast unit, and what well head mixing air temperature sensor 4 adopted is PT100 thermal resistance, and it is arranged on coal master's well head.Frequency conversion fan is arranged on hot blast unit air intake position, heat medium temperature control valve valve body with enter heating agent pipeline and be connected, the electric executing agency of heat medium temperature control valve is connected with PLC.Be widely used in the electronic product in the automatic control of various manufacturing machine and manufacturing process at present for controlling the PLC 1 of frequency conversion fan 2 and heat medium temperature control valve 5.It adopts the memory that can program, be used for storing the instruction of the operations such as actuating logic computing, sequential operation, timing, counting and arithmetical operation therein, and by digital or analog input and output, control various types of machinery or manufacturing process.Be connected with hot blast unit leaving air temp sensor 3, well head mixing air temperature sensor 4, frequency conversion fan 2, heat medium temperature control valve 5 respectively.And the leaving air temp detected and design temperature are compared, and judge difference, regulated by PID proportional integral, electrical network is inputted the alternating current of the 50Hz of hot blast unit, inversion is the alternating current of spatial load forecasting requirement frequency, frequency conversion fan 2 is run between a minimum value and a maximum value, when the minimum air quantity of frequency conversion fan, when still can not satisfy the demand, the open degree of automatic adjustment heat medium temperature control valve 5, control heating agent supply, thus control wellhead temperature, wellhead temperature is made to control (to remain at 2 ° of more than C) in a rational temperature range, the air quantity reduced is exactly the electricity that variable-frequency motor is saved.
