Description
Technical field
The utility model relates to a kind of industrial tolerance compensation arrangement, is particularly suitable for but is not limited only to solve the tolerance compensation arrangement of yellow phosphorus furnace gas filtration system low tolerance running temperature rapid drawdown problem.
Background technology
The furnace gas produced during existing phosphorus production adopts dry filtration technique, containing a large amount of carbon monoxide and phosphorus steam in furnace gas.Because the blower fan dissipated heat in yellow phosphorus furnace gas filtration system is large, temperature will rapid drawdown after entering blower fan for furnace gas, and be ensure system cloud gray model safety, each node temperature of system needs to be greater than dew point.Operationally, for ensureing that gas temperature is greater than dew point, make chuck by e-quipment and pipe and be incubated gas, in chuck, medium is generally safe gas (being generally nitrogen) to current technique.But conduct heat because chuck belongs between gas, nitrogen, to the thermal Finite of material gas transfer, is not enough to the dissipated heat compensating non-chuck position, causes system external loses heat, gas temperature reduces.When the low tolerance of system is run, because gas flow is low, the temperature impact of loses heat on material gas is larger, causes the rapid drawdown of fan inlet gas temperature.If low tolerance is longer for running time, gas temperature will be caused lower than freezing point, material sticks blower interior, and then blower fan operation irregularity may be caused, cause security incident.For making up existing technique solving the deficiency in yellow phosphorus furnace gas filtration system low tolerance running temperature rapid drawdown problem, need a kind of structure simple, the tolerance compensation arrangement with the yellow phosphorus furnace gas temperature rapid drawdown problem when low tolerance well can be solved with low cost.
Utility model content
The utility model provides a kind of furnace gas filtration system tolerance compensation arrangement, for solving the problem of yellow phosphorus furnace gas filtration system low tolerance running temperature rapid drawdown, by the low tolerance problem of Inner eycle loop compensation tolerance resolution system, thus ensure the security of operation of whole filtration system.
The utility model provides a kind of furnace gas filtration system tolerance compensation arrangement, be there is the furnace gas generator and filter element that are connected by inlet channel, described filter element is also connected with scrubbing tower by exhaust passage, and inlet channel is communicated with by circulation canal with exhaust passage.The Inner eycle loop be made up of inlet channel, filter element, exhaust passage and circulation canal is formed by this structure.When the low tolerance of furnace gas filtration system, furnace gas after filtration unit enters exhaust passage after filtering, inlet channel is entered again by circulating line, finally again get back to filter element by inlet channel, complete cyclic process, a part of gas in exhaust passage can be diverted to inlet channel by circulation canal by this process, thus compensates tolerance during low tolerance, solves the temperature decrease exception because low tolerance causes thus.
Further, described inlet channel is provided with the heating unit be connected and the first isolating valve.First isolating valve, controls furnace gas and enters system, and heating unit makes furnace gas temperature in system all the time higher than dew-point temperature, prevent the security of system problem caused because of low tolerance temperature decrease from occurring by the heater heating furnace gas that it contains.
Further, described exhaust passage is provided with the fan unit, monitoring regulon and the second isolating valve, that are connected.Fan unit provides power for furnace gas circulates, monitoring regulon can the throughput of furnace gas or temperature in monitoring system, and control the second isolating valve, slows down furnace gas by reducing opening outflow when the low tolerance of system, more furnace gas is compensated in inlet channel through circulation canal, thus the indirect problem of temperature decrease that causes of the low tolerance of alleviation system internal cause.
Further, described circulation canal is provided with adjusting control valve; One end of circulation canal is connected between monitoring regulon and the second isolating valve, and the other end is connected between the first isolating valve, and heating unit.Such syndeton is adopted to make inlet channel, filter element, exhaust passage and circulation canal form Inner eycle loop, simultaneously by the adjustment to system intrinsic parameter, pipe pressure in guarantee circulation canal is higher than the pipe pressure in inlet channel, the part furnace gas that is filtered can be got back in inlet channel again through circulation canal by this Inner eycle loop when the low tolerance of system and increase tolerance in whole system, thus the problem of temperature decrease that the low tolerance of resolution system internal cause causes.The effect of adjusting control valve is throughput in controlled circulation passage, and the tolerance can coming inner loop loop by increasing or reduce opening carries out control and compensation.
Optionally, adjusting control valve selects intelligent butterfly valve, Intelligent ball valve and intelligent gate valve, and it is large that above structure has capacity, precision high, can reduce in industrial production because of exception that problems with valves causes.
Optionally, circulation canal selects diameter to be more than or equal to the pipeline of 200mm, and owing to may there is dust or the waste liquid dust mixture of larger particles in furnace gas in the industrial production, the pipeline selecting diameter to be more than or equal to 200mm can reduce the exception blocking and cause.
Preferred a kind of structure is, peripheral circuit and the sensor of PLC processing controller and described PLC is provided with in monitoring regulon, by the parameter in sensor real-time monitoring system, the parameter gathered is through the process of PLC processing controller, can the opening and closing of Intelligent adjustment second isolating valve, and adjusting control valve, thus the mechanical intelligent improving whole system reduces cost of labor.
Optionally, fan unit selects frequency conversion fan, in yellow phosphorus furnace gas filtration system during tolerance change, blower fan frequency can be regulated according to actual conditions, when making furnace gas enter blower fan, within the scope of security management and control, (management and control temperature is more than or equal to 190 DEG C to temperature, yellow phosphorus furnace gas dew-point temperature 180.7 DEG C), thus reduce potential safety hazard.
Structure of the present utility model is simple, easy to operate and usage monitoring regulon can reach intelligence control system tolerance, the Inner eycle loop structure consisted of inlet channel, exhaust passage and circulation canal can when the low tolerance of system, tolerance in system is compensated, thus solves the problem of yellow phosphorus furnace gas filtration system low tolerance running temperature rapid drawdown.
Below in conjunction with accompanying drawing, the utility model is further illustrated, realize the utility model to enable those skilled in the art.
