Abstract
The utility model discloses a protective gas's system that recycles in bell -type furnace belongs to metalworking and thermal treatment technical field, including the low pressure gas holder that communicates in proper order, pressure balance jar, cooling water set, level filtering ware, compressor unit, high pressure gasholder no. 1, secondary filter, oxygen -eliminating device, heat exchanger, sorption drying regenerator, tertiary filter, high pressure gasholder no. 2, distributor, the air inlet of its middle and low voltage gas holder and the exhaust port of bell -type furnace intercommunication, the gas outlet of distributor and the protective gas air inlet of bell -type furnace intercommunication, the distributor still is connected with hydrogen nitrogen blender simultaneously. The utility model discloses carry out purification treatment to discharged waste gas, wherein active ingredient retrieves, through the distribution and detect after qualified, carry the bell -type furnace again as the qualified protective gas of cleaning in to realization protective gas's cyclic utilization, the consumption and the energy consumption of reduction raw and other materials, the product reaches heat treatment's quality standard requirement simultaneously.
Description
Technical field
This utility model relates to the circulating-use equipment of protective gas in bell furnace, belongs to intermetallic composite coating and technical field of heat treatment.
Background technology
At present at metallic article, as in the heat treatment process that copper strips, steel band are processed, general employing bell furnace carries out heat treatment process to copper strips.Traditional technique is the nitrogen hydrogen hybrid protection gas in single use bell furnace, and waste gas directly to airborne release by pipeline, is not only increased production cost, and pollutes atmospheric environment.
Summary of the invention
For solving the problems referred to above, this utility model provides a kind of can carry out the recycling system of protective gas in purified treatment, and the bell furnace of recyclable recycling to the waste gas of bell furnace discharge.
For achieving the above object, the technical scheme that this utility model is used is:
The recycling system of protective gas in a kind of bell furnace, including the low pressure gasholder being sequentially communicated, pressure balancing tank, handpiece Water Chilling Units, first order filter, compressor bank, high pressure tank one, second level filter, oxygen-eliminating device, heat exchanger, adsorption dry regenerator, third level filter, high pressure tank two, allotter；Wherein the air inlet of low pressure gasholder connects with the Waste gas outlet of bell furnace, and the gas outlet of allotter connects with the protective gas air inlet of bell furnace, and allotter is also associated with hydrogen nitrogen blender simultaneously.
Wherein, pressure balancing tank scalable pressure inside the tank and bell furnace exhaust velocity.Hydrogen nitrogen blender can according in copper strips, steel band or other metal product heat treatment processes to protection gas different demands, it is provided that fresh hydrogen or hydrogen nitrogen mixed gas.Gas recovery composition is adjusted by this utility model by supplementary fresh process gas, reaches to produce by the mixed gas of required ratio.
This utility model is for bell furnace equipment, the feature of protective gas; use gas purge system and distinctive recovery technology; discharge waste gas is carried out purified treatment; to wherein reclaim by effective ingredient; through distribution and detect qualified after, be re-delivered in bell furnace as clean qualified protective gas, thus realize recycling of protective gas; reducing raw-material consumption and energy consumption, product reaches the quality criteria requirements of metal heat treatmet simultaneously.
Accompanying drawing explanation
Fig. 1 is system structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1; the recycling system of protective gas in this utility model bell furnace, including the low pressure gasholder 1 being sequentially communicated, pressure balancing tank 2, handpiece Water Chilling Units 3, first order filter 4, compressor bank 5, high pressure tank 1, second level filter 7, oxygen-eliminating device 8, heat exchanger 9, adsorption dry regenerator 10, third level filter 11, high pressure tank 2 12, allotter 13.Wherein, the air inlet of low pressure gasholder 1 connects with the Waste gas outlet of bell furnace 14, and the gas outlet of allotter 13 connects with the protective gas air inlet of bell furnace 14, and allotter 13 is also associated with hydrogen nitrogen blender 15 simultaneously.
In this utility model bell furnace, the operation principle of the recycling system of protective gas is as follows: the waste gas of bell furnace 14, after low pressure gasholder 1, pressure balancing tank 2, after delivery temperature is reduced by entrance handpiece Water Chilling Units 3, enters back into first order filter 4；Through the gas of first order filter 4, enter compressor bank 5, after pressurization, by high pressure tank 1, enter second level filter 7；Gas after double-filtration, through oxygen-eliminating device 8 and heat exchanger 9, enters adsorption dry regenerator 10, enters back into third level filter 11；Gas through three-stage filtration is stored in high pressure tank 2 12; gas in high pressure tank 2 12 enters back into allotter 13; carry out being mixed to form qualified protective gas with the new hydrogen supplemented or hydrogen nitrogen mixed gas; this protective gas is transported in the protective gas air inlet of bell furnace 14 (protective gas can be simultaneously dispensed in multiple bell furnace 14 by allotter 13 according to being actually needed of producing) the most again by allotter 13.The new hydrogen supplemented or hydrogen nitrogen mixed gas, provided by the hydrogen nitrogen blender 15 being connected with allotter 13.
This utility model is simple to operate, and security reliability is good, and the surface of product and performance reach the quality criteria requirements of metal heat treatmet, can reduce raw-material consumption and energy consumption simultaneously, reduces cost, and reduces the gas discharge pollution to environment.
Above-described embodiment is only used for illustrating inventive concept of the present utility model, rather than the restriction to this utility model rights protection, all changes utilizing this design that this utility model carries out unsubstantiality, protection domain of the present utility model all should be fallen into.
