Abstract
The invention discloses a heating device special for a compressed natural gas decompression pry and relates to a heating device. The heating device special for the compressed natural gas decompression pry comprises a box body. A triangular reinforcing rib is arranged on the outer surface of the box body. An electric heater, a heat exchanging medium and a gas way pipeline are arranged in the box body. The heat exchanging medium is anti-freezing rust-proof liquid. The two ends of the gas way pipeline are connected with a gas inlet and a gas outlet respectively. The gas way pipeline does not make contact with the electric heater. A liquid inlet and a liquid outlet are formed in the box body. A liquid level sensor and a temperature sensor are arranged on the top of the box body. The liquid level sensor, the temperature sensor and the electric heater are electrically connected with a control display box though an anti-explosion electrical pipeline. A temperature adjustor is arranged in the control display box. The heating device special for the compressed natural gas decompression pry is small in size, stable in temperature and high in efficiency. By the adoption of the heating device special for the compressed natural gas decompression pry, the phenomenon of ice blockage can be effectively eliminated, the pressure of an outlet is stable, and the use demand is met.
Description
Technical field
The present invention relates to a kind of firing equipment, relate in particular to a kind of Special heating device for compressed natural gas pressure reducing pry.
Background technology
Compressed Gas, in decompression pressure regulation process, because gas volume changes, produces heat absorption phenomenon, easily produces " ice is stifled " phenomenon at the relief pressure valve cartridge position of pressure regulator.Making to work off one's feeling vent one's spleen to press produces fluctuation, even makes depressurized system decompression lose efficacy.Existing settling mode is on pipeline, to install hot water circuit water jacket additional, is gas-heated.Circulating hot water adopts boiler or other water heaters to heat.The method equipment volume is large, and heating-up temperature is unstable, inefficiency, and energy consumption is high.Inadaptable especially for the compressed natural gas that thermal capacitance value is higher.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of Special heating device for compressed natural gas pressure reducing pry, and equipment volume is little, temperature stabilization, and efficiency is high.Can effectively solve " ice is stifled " phenomenon, make outlet pressure stable, meet and use needs.
Technical scheme of the present invention is: a kind of Special heating device for compressed natural gas pressure reducing pry, comprise casing, box outer surface is provided with triangle ribs, in casing, be provided with electric heater, heat transferring medium and gas path pipe, described heat transferring medium is antifreezing and anti-rust liquid, the two ends of gas path pipe connect respectively air inlet and gas outlet, and gas path pipe does not contact with electric heater; On casing, be provided with inlet and liquid outlet, casing top is provided with liquid level sensor and temperature sensor, and liquid level sensor, temperature sensor and electric heater are electrically connected with controlling show case by explosion-proof electrification pipeline, control in show case and are provided with thermoregulator.
As preferably, described casing is carbon steel incubator, is provided with Pressure gauge on air inlet, and described gas path pipe is Stainless Steel Coil, is provided with discharging valve on liquid outlet.
As preferably, described explosion-proof electrification pipeline installing is in the anti-explosion terminal box of wall box, and wall box is provided with liquid level gauge and thermometer, and thermometer stretches in heat transferring medium.
The invention has the beneficial effects as follows: the present invention uses electric heater heat exchanging dielectric heating in casing, makes gas path pipe preheating, while making it pass through pressure-reducing valve, can not make pressure-reducing valve freeze, equipment volume is little.Casing is carbon steel incubator, saves the energy, improves the thermal efficiency.Gas path pipe adopts Stainless Steel Coil, improves heat exchange efficiency.Heat transferring medium is antifreezing and anti-rust liquid, can prevent at temperature lowlyer, and device is not when used, and the icing situation of heat transferring medium occurs; Casing is steel construction in addition, adopts antifreezing and anti-rust liquid can prevent the generation of iron rust.Whether liquid level sensor can be monitored heat transferring medium in real time enough, lower than lower, prescribes a time limit, and is controlling show case alarm.Temperature sensor can be monitored the temperature of heat transferring medium in real time, and can, by controlling show case set temperature, make heating-up temperature constant.It is safer that explosion-proof electrification pipeline and anti-explosion terminal box allow the present invention use, and avoids the generation of accident.Thermometer and liquid level gauge are convenient for people to externally confirm temperature and the liquid level of heat transferring medium, very convenient and practical.
