Abstract
A kind of methanol evaporator applied to high-concentration formaldehyde production system of the utility model, including sequentially connected upper tube box, tubular heat exchanger and lower tube box, the upper tube box upper end opens up air inlet exhaust gas, and methanol spray tube is installed in upper tube box, several spray heads are set on the methanol spray tube, the tubular heat exchanger includes cylinder, on cylinder, in lower setting, lower perforated plate, on, lower perforated plate is separately connected upper tube box and lower tube box, on, heat exchanger tube is connected between lower perforated plate, heat exchanger tube is connected to upper tube box and lower tube box, it is placed outside the cylinder, under be respectively set formaldehyde outlet and formaldehyde import, methanol mixed gas outlet is arranged in the lower tube box lower end, the methanol evaporator applied to high-concentration formaldehyde production system generates methanol gaseous mixture by the heat of vaporization of formaldehyde finished product, methanol and air, tail gas good mixing effect, and it steams It is few to send out device energy consumption, and the temperature of formaldehyde gas can be reduced.
Description
Technical field
The utility model relates to formaldehyde production equipment more particularly to a kind of methanol applied to high-concentration formaldehyde production system
Evaporator.
Background technique
Need to consume methanol gaseous mixture in formaldehyde production, methanol gaseous mixture is mixed simultaneously by methanol, air and tail gas
It evaporates, the mixed effect in traditional evaporator is undesirable with air, tail gas for methanol, and evaporation process energy consumption is larger.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of applied to high-concentration formaldehyde production system
Methanol evaporator.
Technical solution used by the utility model is as follows:
A kind of methanol evaporator applied to high-concentration formaldehyde production system, including sequentially connected upper tube box, tubulation change
Hot device and lower tube box, the upper tube box upper end opens up air inlet exhaust gas, and methanol spray tube, the methanol are installed in upper tube box
Several spray heads are set on spray tube, and the tubular heat exchanger includes cylinder, and upper and lower tube sheet, upper, lower tube is arranged in cylinder above and below
Plate is separately connected upper tube box and lower tube box, and heat exchanger tube is connected between upper and lower tube sheet, and heat exchanger tube is connected to upper tube box and lower tube box,
Formaldehyde outlet and formaldehyde import is installed above and below in the tank body periphery, and methanol mixed gas outlet is arranged in the lower tube box lower end.
As a further improvement of the above technical scheme:
The upper tube box side also sets up venting, and mounting base is arranged in the lower tube box two sides.
The beneficial effects of the utility model are as follows: the methanol evaporator applied to high-concentration formaldehyde production system, empty
Gas and tail gas enter upper tube box from upper end, while misty methanol and air are sprayed from spray head for methanol spray tube and tail gas is mixed
It closes, good mixing effect, exchanges heat by the formaldehyde gas in heat exchanger tube and shell side, evaporation can be heated and generate methanol gaseous mixture, benefit
Most of methanol evaporation is mixed with air, tail gas with the heat of formaldehyde gas, reduces evaporator energy consumption, while formaldehyde is so incensed that drop
Temperature.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figure 1, the methanol evaporator applied to high-concentration formaldehyde production system of the present embodiment, including be sequentially connected
Upper tube box 1, tubular heat exchanger 2 and lower tube box 3,1 upper end of upper tube box opens up air inlet exhaust gas 11, and installing in upper tube box 1
Methanol spray tube 4, several spray heads 41 are arranged on methanol spray tube 4, and 1 side of upper tube box also sets up venting 12, tubulation heat exchange
Device 2 includes cylinder 21, and cylinder 21 is arranged upper and lower tube sheet 22,23 above and below, upper and lower tube sheet 22,23 be separately connected upper tube box 1 and under
Bobbin carriage 3 connects heat exchanger tube 24 between upper and lower tube sheet 22,23, and heat exchanger tube 24 is connected to upper tube box 1 and lower tube box 3, outside cylinder 21
It encloses and formaldehyde outlet 25 and formaldehyde import 26 is installed above and below, methanol mixed gas outlet 31, lower tube box 3 is arranged in 3 lower end of lower tube box
Mounting base 32 is arranged in two sides.
The methanol evaporator applied to high-concentration formaldehyde production system in use, air and tail gas from air tail gas into
Mouthfuls 11 enter upper tube box 1, while methanol spray tube 4 sprays misty methanol by spray head 41, by misty methanol and air and
Tail gas mixing enters heat exchanger tube 24 after mixing, while formaldehyde gas enters the cylinder 21 of tubular heat exchanger 2 from formaldehyde import 26
It is interior, 25 discharge of formaldehyde outlet after formaldehyde heat exchange, while the interior evaporation of heat exchanger tube 24 forms methanol gaseous mixture and enters lower tube box 3, finally
It is discharged from methanol mixed gas outlet 31, into methanol cold mixture heater, preheating is used.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
