Description

Stove is used heat exchanger

Technical field

The utility model relates to the technical field of heat exchanger, more particularly relates to the technical field of combustion furnace with heat exchanger.

Background technology

The casting industry smelting furnace is one of a kind of main equipment, no matter be that aluminium ingot or ingot iron all need place it in earlier to be smelted in the smelting furnace and liquidly cast again, at present; The needed energy of smelting furnace work on the market mainly contains four kinds of liquefied gas, natural gas, electricity and fire coals etc., no matter use which kind of energy, the consumption performance of its energy is very big; And rate of energy is also lower; The chimney that mainly shows body of heater directly effluxes the heat energy in the stove, and the heat at its exhaust opening place is very high, and the heat of this part has just been wasted; Not only polluted the environment in operation workshop; Unfavorable environmental protection, and caused the significant wastage of the energy, strengthened production cost of products.

The utility model content

The purpose of the utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and cost of manufacture is lower, helps environmental protection, can the stove that heat energy carries out recycling be used heat exchanger.

The technical solution that the utility model adopts in order to solve the problems of the technologies described above is following:

Stove is used heat exchanger; It mainly is made up of shell, flue tube, air inlet pipe and blast pipe, and said shell is the tubulose of closed at both ends, offers corresponding hole at the two ends of this shell; Said flue tube is positioned at shell; And its two ends communicate with the external world through the hole at shell two ends respectively, also offer air inlet and exhaust outlet respectively in the both sides up and down of shell, said air inlet pipe and blast pipe respectively with shell on air inlet and exhaust outlet be connected.

Said flue tube is parallel shape and gathers in the enclosure.

It also includes water tank, water inlet pipe and drainpipe; Said water tank is positioned at the upper end of shell; And its set inside has the smokejack that is connected with flue tube; Both sides up and down at this water tank offer water inlet and discharge outlet respectively, said water inlet pipe and drainpipe respectively with water tank on water inlet and discharge outlet be connected.

Be installed with heat exchanger fin on the smokejack lateral wall in the said water tank.

The top of said water tank offers relief hole.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model is simple in structure; Low cost of manufacture, utilize smoke exhaust pipe with the temperature exchange of flue gas in the air of shell, utilize blower fan that the hot-air of shell is blasted in the body of heater again; Thereby realized the recycling of heat energy; So not only can protect the environment in operation workshop, and well realize the recycling of the energy, practice thrift the energy greatly; The hot cigarette of discharging from flue tube absorbs heat through the heat exchanger fin of water tank more once more; Thereby the water in the water tank is heated; Realized the absorption once more of heat energy, the fume afterheat that effluxes at last reduces greatly, and the hot water in the water tank can also be used to preheating liquefied gas bottle or shower.
