Product introduction

Rising film evaporator and climbing film evaporator, it is based on the principle of siphon pump operation, according to the steam bubbles in boiling process of the lift, at the same time, flow, liquid and steam flow and steam production increase, thus, to produce a flow film on the tube wall, the liquid upward climb". And flowing upward, with ribs, producing a high degree of turbulence in the liquid.

Spiral plate heat exchanger is a kind of high efficiency heat exchanger. It is equipped with practical steam, steam, steam, liquid, liquid and liquid. Spiral plate heat exchanger, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries. According to the layout situation, it can be divided into no detachable type (type I), spiral plate type and detachable type (type II, III type) spiral plate heat exchanger.

Layout performance

1, This set of equipment deployment consists of two roll to form two symmetrical spiral channel, two kinds of heat transfer medium at full countercurrent activities, greatly enhance the heat transfer results, even small temperature difference between two kinds of medium, can achieve the ideal heat transfer.
2, On the shell accept tangential layout, local resistance, due to the curvature of the spiral channel is symmetrical, the liquid in the set equipment deployment activities without large steering, the total resistance is small, thus the progress plan flow which has high heat transfer capability.
3, I type can not remove type spiral plate heat exchanger spiral end of the channel to accept welding sealing, so it has higher sealing. Layout principle diagram.
4, II type detachable spiral plate heat exchanger layout principle and not demolition type heat exchanger is similar, but in this one channel can be opened to wash, especially practical, sticky, with precipitation liquid heat exchange.
5, III type detachable spiral plate heat exchanger layout principle and not remove the same type of heat exchanger, but its two channels can be opened for washing, practical range of wider.

Anti blocking principle

Spiral plate heat exchanger and usually tubular heat exchanger is not easily blocked, especially in sediment, small shells and other suspended particles impurities deposition within the spiral channel, an important table now:
1. Because it is the deposition of single channel impurities in the passage formed turnover flow also will progress to flush it out;
2. Because the helix channel does not have the dead angle, the impurity is easy to be rushed out.

Product features

1, High efficiency heat transfer (performance):
As the heat transfer usually think of the spiral plate heat exchanger to heat exchanger is tubular 1-3 times. There is no uniform single channel activities of death area, distance and column spiral channel low Reynolds number fluid of active disturbance, water water heat when the spiral plate heat exchanger heat transfer coefficient up to 3000W/ (m.K).
2, Accept useful low-temperature heat
The spiral plate heat exchanger is made up of two coils, and the waste heat is accepted to make full use of the low temperature heat energy.
3, The operation reliability is strong, can not remove type spiral plate heat exchanger spiral Channel end face accept welding sealing, and thus have higher sealing, ensure two things medium is not confused.
4, Small resistance of
Acceptance, acceptance, tangential layout on a shell. Relatively low pressure loss, large capacity steam or gas disposal punishment; self cleaning ability, because of its medium spiral type, no dirt deposition; easy washing, steam or lye washing, simplicity, proper placement of the washing device; the media channels, other than the allowable velocity of heat exchanger is high.
5, The use of multiple
When a single set of equipment deployment can not be satisfied with the use of requirements, multiple units can be used together, but the group must meet the following requirements in a timely manner: parallel combination, series combination, set up, equipment deployment and channel spacing similar. Confusing combination: one channel in parallel, one channel in series.

Use clarify

1, The establishment of equipment deployment, should be familiar with the system process engineering skills staff guide, according to the book of instructions and product quantity certificate and its system, process characteristics, determine the placement process plan. In the arrangement, should consider, just to facilitate the use of the pipeline to absorb thermal expansion, and installation to level, right, and can not produce additional stress, so as to avoid the unfortunate impact of the deployment of equipment. The two coordinate combined pipe flow are the current state, in order to improve the results of heat transfer.
2, Should be installed before washing the pipeline system, shall not be mud, sand, debris, etc., remain here; check whether the heat exchanger in transit damage, whether there are large debris falling into the pipe mouth.
3, The establishment of equipment deployment, resettlement, equipment deployment and system should be held hydrostatic test.
4, After the hydrostatic test, the equipment should be installed to hold thermal insulation.
