Description
Technical field
The utility model belongs to chemical plating plant field, especially relates to a kind of primary heater unit of chemical plating plant.
Background technology
In electroless plating, produce in the process of welding wire, need to provide a large amount of tap water to electroless plating production line, and heat simultaneously, each supplementary cold water needs a large amount of thermals source just can reach the temperature needing, and can expend the more energy.In the production plant of welding wire, have coal furnace thermal source is provided, lead to interior can the discharge by a large amount of high-temperature gas of generation of chimney of atmosphere, atmosphere is caused to thermal pollution, cause tropical island effect.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of primary heater unit of chemical plating plant, can make full use of the heat of stack gas, and electroless plating water bath water is carried out to preheating.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of primary heater unit of chemical plating plant, comprise flue, be located at flue inside interchanger, connect the electroless plating water bath and the tank from the beginning that is connected interchanger downstream of interchanger upstream, between described interchanger and electroless plating water bath, by supply pump, be connected, the two ends of supply pump are respectively equipped with variable valve.
Further, described interchanger is shell and tube heat exchanger, and its inside is provided with some tubulations along flue direction, and in flue, waste gas enters shell and tube heat exchanger by the inlet mouth of tubulation, and enters flue by the air outlet of tubulation.
Further, described shell and tube heat exchanger and be provided with from the beginning variable valve between tank.
Further, described tubulation outside parcel one deck fin, plays the effect of heat radiation to a greater extent.
Further, described fin is spirrillum, is wrapped in tubulation outside, and fin thickness is 2mm, can reach optimum radiating effect.
Further, described tubulation outside is provided with some baffles, and tap water flows between tubulation outside and baffle, and baffle forms around labyrinth type, and water is tortuous mobile inside, the heat in can more large-area reception tubulation.
Further, the inlet mouth of described shell and tube heat exchanger and place, air outlet are equipped with a cavity, the size of cavity cross section and the cross section of shell and tube heat exchanger are wide, between cavity and tubulation, establish a baffle plate with the hole communicating with tubulation, baffle plate is fixed on the inwall of shell and tube heat exchanger, and fixes with some tubulations, cavity can collect the hot gas in flue, enter each tubulation, and then be pooled to the cavity of air outlet, enter flue.
Advantage and the positively effect that the utlity model has are:
1. for water on electroless plating production line carries out preheating, for production line provides a certain amount of and with the hot water of certain temperature, can reduce the waste of the energy;
2. can make full use of hot gas in flue with heat, to tap water, heat;
3. reduce smoke stack emission temperature, to reach discharging standards;
4. interchanger internal structure is reasonable in design, and tap water can absorb the heat of waste gas greatly.
