Abstract
Boiler heating and anti-freezing system for tunnel fire-fighting, comprise fire-fighting looped network, cistern, two outlet pipes of cistern are by a cross current, a water pipe is provided with No. two water pipes and connects fire-fighting looped network single tube formation circulation line, on a described water pipe, be provided with hot-water boiler, water circulating pump, thermocouple, magnetic valve and stop valve, on described No. two water pipes, be provided with stop valve, on two outlet pipes of described cistern, be provided with magnetic valve, described hot-water boiler, water circulating pump, thermocouple, magnetic valve, stop valve is all connected with intelligent controller signal, described intelligent controller signal connects low-voltage distribution cabinet.Good freezing protection effect, not waste water resource, automaticity is high.
Description
Technical field
The utility model relates to tunnel fire-fighting winterization system.
Background technology
Extremely frigid zones winter temperature is low, and freeway tunnel fire demand water easily freezes and be ineffective.The freeway tunnel fire demand water of prior art does not generally all arrange watertight conduit, even if be provided with the also outer variations in temperature of nernst cell and waterproof automatically of fire-fighting guard tube, thereby it is antifreeze effectively to carry out tunnel, if moreover the rare employing of the regional water resource adjutage having discharges water and can cause great lot of water resources waste, be further improved.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of good freezing protection effect, not waste water resource, the boiler heating and anti-freezing system for tunnel fire-fighting that automaticity is high.
For realizing the utility model object, provide following technical scheme: tunnel fire-fighting boiler heating and anti-freezing system, comprise fire-fighting looped network, cistern, it is characterized in that two outlet pipes of cistern are by a cross current, a water pipe is provided with No. two water pipes and connects fire-fighting looped network single tube formation circulation line, on a described water pipe, be provided with hot-water boiler, water circulating pump, thermocouple, magnetic valve and stop valve, on described No. two water pipes, be provided with stop valve, on two outlet pipes of described cistern, be provided with magnetic valve, described hot-water boiler, water circulating pump, thermocouple, magnetic valve, stop valve is all connected with intelligent controller signal, described intelligent controller signal connects low-voltage distribution cabinet.
As preferably, hot-water boiler comprises cylindrical shell, flue, base, and flue is arranged in cylindrical shell, and described flue is followed successively by upper furnace, fire tube, lower furnace from top to bottom, and upper fire tube is communicated with upper furnace and lower furnace, and fire tube is set at least one.
As preferably, described intelligent controller comprises PLC, touch-screen and control room, tunnel management station computer, uses EPA communication between three.
As preferably, thermocouple is stainless steel armour formula RTD.
The beneficial effects of the utility model: the utility model is applicable to water resource desert, greatly reduces water resource waste, and automaticity is high, can be to the antifreeze Real-Time Monitoring that carries out of tunnel fire demand water, and antifreezing effect is good.
